(When Object "K" was undertaken there were two test stands erected at Zavod II and later four more were shipped in from LENINGRAD. 50X1-HUM high altitude test chamber from the Junkers Plant was brought to Zavod II in disassembled pieces. It was never erected and was later sold to another plant near MOSCOW in a corroded condition. 4. In 1947 the test stand erection had progressed sufficiently and testing began on components of the BMW-003 and the JUM0-00h. Development work was also started on the JUM0-012. These then were the first powerplants of German origination to undergo development at Zavod II and had become an important function of the experimental phase within the Ministry for Air. Later, in the spring of 1952, these older test stand Units were com- pletely dismounted and a new one consisting of six units constructed. One of the units from the old test stands WAS used as No. 7 and mounted perpendicular to the others and at one corner of the building. ? ?

The chief Soviet designer KUZNITZOR, who came from MOLOTOV, once made A trip to MOSCO and shortly after returned. BLADE and a 50X1-HUM General LIN came to Germany to see about starting a new industry within UK Vf the DDR. The ';oviets then were telling the Germans at Zavod II about re- building PIRNA, DESSAU, etc. They were promising them that some day they would all go back to Dermany and work on aircraft again within this industry.. They were even given an allocation of quarters as commensurate with their position. About the end of 1352 they heard that much building was going on in DESSAU due to the influence of SAADE and that they would be re-situated in this center of the new industry. 50X1-HHUM 6. About MAY of 1953 DIM was in a state of collapse. fl 7. all work in DESSAU. PIRNA and SOUS. many specialists at Zavod // seemed ,50X11-IUM think that EDC had an effect on this industry collapse. There were no publications in the newspapers about the uprisings but within the UTIR it was known. The Russians openly blamed the Americans for it. Although they were publicly blaming the Americana for it they griped at the Germans there in YTJTRYSWEII for it also. 50X1-H UM From about December 1952 through June 1953 the ?;oviets seemed to ignore the German specialists and didn't so much as try to obtain any assistance in learning anymore about the various projects. These Soviet workers did their job alone more and more until they were self-sufficient. They would work alone and do their job over and over until they understood how. 50X1 HUN this was a dictated policy from the Ministry fot Air. The Germans were told in 1952 they were to be repatriated and most of the workers seemed to develop a passive resistance and steadily in- creasing loss of interest in their work. They were afraid that in enter- ing new projects they may be kept there longer. It was noticeable by the Germans that the Soviets in charge didn't like the idea of their not going home either. luring 1952 and 1953 tension increased and VOGEL once ap- proached a Soviet by the name of SEMENOFF, who was always present at the Official State Test runs, and who came from the Ministry for Air. He asked, "117 can't we go home?" SENENOFF answered this by saying that it had all been discussed within the Ministry and everything was cleared for this move, but that something within security that he didn't know about came up and had hindered its progress, there seemed to be a definite change taking place in the security phase of events there due to the BER/A complex. 50X1- NOTE: 7141S DOCUMEN T CONTAINS INFORMATION AP EECTING Frit ICNAL 1:1,E1:44:.1 OE THE UNIT' .)

OBJECT.00,2 As 09flerkil 50X1-HUM \ PAGE OF PAGES 1, The BMW 003C was being developed by the BMW Plant in the Soviet Zone of Germany. The 003-42 had some slight external changes made in East Germany in 1966. A working model was taken along with plant and test stand facilities as reparations in 1946 to the USSR. The 003C underwent development from summer 1947 through minter of 1948. The "C" model 42 it was produced had different combustion chambers which were a development of the "A2" model. This was meetly in re-routing of the cooling air to produee greater volume. There were also changes in the turbine bbuket design. There were some changes made here too, to pass a greater volume of air for cooling the turbine buckets. The A-2 model had 800 kg thrust, the same as the A-1 model, but the 0030 had 1000 kg thrust. (Natal This is quite low for the 003 models. It should be closer to 1800 kg and 2000 kg.) 2. There were various material tests being run on the turbine buckets of the pre-production models of the 0030. Sone changes occurred in bucket ma- terials and shapes. A newer type fuel regulator was also used. This newer regulator had an accelerator valve that was built externally into the system. It was mounted on the compressor section and connected to th regulator. Its function was designed to squirt more fuel into the burners through separate jets to the spray nozzles for quicker accelerate. tien. This was essentially based on the carburetor acoelerator pump con- Aeption. (Note: This system was later built integral into the regulator and used on Objeot A-022).

Special Tests (1) Special Tests were run for special experimental testing to solve a particular problem) or to test a particular component such as .compressor tests, or limit load tests, etc. The first series of tests were compressor tests. Here there were readings of all stages of the compressor., This was to cross check pressure rises against theoretical rises in blade designs and to facilitate the ' completed compressor developments. Then, there were oil circu- lator tests along with fuel system pressure checks. Here the fuel pressure was read before the pump (at pump inlet) and after the pump (pump outlet) And in front of the injection nozzles. The oil pressure and temperature readings were taken also at various places, mum liii. 191.11141 NI oNIAlpe. op/IAA:P w All11.11tp. lilt NA iuNAL 1,111.NGA. 01 1111 IINIII WO A II '? WIIII1N MI ANUS.

These Prandtl tubes were linked to manometers using mercury and some using kerosene. Generally there were two types of readings taken One measurinv, ( 4.) dynamic, and (-) static pressures to- gether. And the other taking only static pressure readings. The Prandtl tubes could be adjusted to various depths into the slipstream by merely sliding in and out to adjustment by clamping tight with ring clamps. There were special tests run with these tubes at various depths. For the endurance tests the position selected was halfway between the outer engine air intake ducting ring and the intake spinner dome. Reading pick-off points P, P2, and P6 were used to take static pressures only and consisted of a one millimeter hole in three places spaced evenly around the cir- cumference and all leading to a single manometer. These mano- meters were made of a "U" tube holding kerosene. Sometimes with the Prandtl tubes, pitot pressures were plotted against the static pressure at the same point and the difference was recorded as the differential pressure. The manometers were of flerman de- sign and manufacture. Later) as some were brokon, they were re- planed by Soviet manufactured manometers. These Soviet pressure gages were of ,theial indicating type similar to the German de- si 'ed ones. Nowak/or, these did not work well and so the mercury were reverted' to. At first all manometer tubes were read by ratans andinotehl on a NORFORY sheet. /n addition to this th? were photdgraphed. later all readings were photographed cagy. This wasi. done by the Soviets. ;. There was no p4e-determined time allocated to the special test runs. They woUld run as long as required for the tests and then be 'shut down. There would sometimes be long periods that the engines would be left at on a pre-determined setting. This was to let all readings steadily settle down. Temperature readings were taken in. three different places. (4 Ta (atmosibere) was read somewhere near the intake ducting. (b) T2 was taken directly behind the compressor. (o) Temperature readings were taken in the combustion chamber at the head of the chamber near the intake guide vanes. (d) T6 was the tailpipe temperature readings taken in the tail- pipe. T2 and 16 while being taken were done at various depths from the outside surface. Veasurements were recorded by thermocoupling. Temperature readings were sometimes read near the turbine instead of at the head of the combustion chanter, but this was never at maximum parer output. Tachometer readings during all special test rims were always cross checked for calibration. Other checks were' Accessory checks, generator checks, including checks on generator cooling efficiency. ? ?, .?, ?... ..1:1.,?.41 IIIIN.I t.i .1hri I. ..V11:104 MI 4t.t114.

The enduran e tests on the 003C began in 1948 with the first powerplants undergoing special attention in the preliminary in- specticns. The first hour of the test running was along the following pattern: ( f ) ( g) The engine is brought up to starting RPMes (about 800 RPMks by an electric pendulum type motor and the ignition plugs activated. Gasoline els pumped into the starting manifold which leads to the four starting injection spray nozzles which in turn sprays fuel into the burner near the ignition plugs. After atomization and ignition, and when a fire is burning evenly around the annular cam, the speed is brought up to 1100 RPMIs by the throttle controlh Here kerosene is in- jected into the burners by the normal manifold and the gaso- line is simultaneously stopped. The RP)'s are then increased to 2000 and steadied momen- tarily while the idnition plugs are shut off and the start- ing motor is disconnected. The RPM1s are again increased to around 3000 to 4000 and held constant. Here a check is made on: (1) Tailpipe temperature .(2) Oil temperature (3) Oil pressure (L) Fuel pressure (5) Leaks for fuel and/or oil (6) General inspection by mechanic for loose connections, etc., on the external part of pcwerplant If all appears satisfactory the engine is then slowly ad- vanced to maximum take-off poser of 10,000 RPM1s. Here it is steadied again and the (variable tail cone outlet) ex- haust ncezle area is adjusted to obtain 1000 kgt (thrust). Here the first hour of testing begins. For the first five minutes the engine is run at full power and all measurements are carefully taken at the beginning and again at the end of this period. Exhaust gas velocities are measured by a tri-hole tube called a "measuring cylin- der", (see Sketch No. 8 )0 This cylinder has three holes drilled in it and could be rotated by a control linkage from the test control room. The cienter hole would be directly into the slipstream when the cylinder is rotated so that the two outer holes have their pressures equalized. At various RPM's this direction would change and the system was desi.sied to obtain a more accurate pitot pressure read- ings. These tubes have five levels of holes and sometimes for special tests all levels are linked to manometers. But for the endurance tests the middle depth is used. OH l?

This scrapping was on a general basis and other older powerplants were also scrapped at that time There was a large number of cans to the 012 burners manufactured and when the project was halted they became surplus. They were later used as waste baskets. The man who suggested the cans be used for this purpose received a 6 month's pay increase bonus. 2. In the spring of 1953 an 012 Was used to assist in the air flow calibra- tion for the intake ducting for Objects "K" and "D". This was ac- complished by connecting an aluminum tubing from the intake ducting of th "K" to the intake of the 012. Then, by running the 012 they passed the air mass through the "K" ducting and could thus take readings which were used for calibration. B.

In 11-stage axial flow compressor of welded steel plate co struction with a stator blade ring welded integral. The stator ring consisted of the two rings, an outer ring and an inner ring. The stator blades were welded to the outer ring and then inner ring alternately, The inner ring formed the static part of the bullet housing to the drive- shaft. Then, at intervals of about every 12 inches around the outer ring, a lock pin was installed to hold the whole stator ring on and to keep it from rotating about the in- side of the casing plate. The rotors were of solid aluminum alloy in the first half section and of steel in the latter ha F of the assembled section. There were air pressure relief valves on the compressor section housing which were hydraulically operated in the 0128 models and mechanically operated in the earlier 012 engines. Those were to relieve compressor surges at lot RPMts and in starting and during acceleration. Combustion., ,,, ** 6 interconnia;ted,tUbular Steel combustion chambers of the straight through flow type with two fuel injection nozzles. One injection nozzle was for normal running and one for starting only, Turbine 2-stage axial flan turbine consisting of solid steel alloy construction, (Note: On one test a turbine flew apart and one turbine blade penetrated the walls and entered the next test stand d, it was solid steel), fthaust Nagle Variable adjustable type with steel outer casing and meohanioally adjustable inner cone. Fuel System Fuel system of dual manifold type,. The starting fuel system was separated from the running fuel system,? Both manifolds were controlled from a single fuel control unit ' and the switch from gasoline to kerosene was made at the regulator when engine reaches sufficient Mrs. The fuel pump. was a Soviet manufactured copy of the BAFOL40 German designed pump. Of this, there were two types: 1. Rated at 1400 ltr/min. 2. Rated at 1600 ltr/min. The 1600 ltr/Min capacity pump was used on the 012 and the 11400/1tr/min pump was used on the BMW 003C and JUMO 004 powerplants. (Notes These pumps ,were series produced in the USSR).

OBJECT 018 A. General 1, Di 19146 within the Soviet Zone of Germany, the BMW group had under development the BMW-018. This was constructed and brought to the test stand for testing but was never run. It was motored over for compressor and turbine blade checks but never fired up. Although the 018 was in the project stage of development in 19145 it was mostly developed by the BMW plant after occupation and until late 19/46? 2, Late in 1914 and early 19)47 the test stand was erected at Zavod /I to test the 018. This was the same stand 'that this powerplant was suspended on in Germany. it was merely reconatructed in the USSR? However, the powerplant suspension was changed. in Germany the suspension was over- head, but at Zavod II it was from below. This one engine that *as brought from.Germany was the only 018 that was pro-50X1-HUM ducede it was the only one that underwent testing at Zavod II, 3. About the end of 1947 this powerplant was put on the test stand and ignited, for the first time. The primary tests were a failure. It was not run to very high Mita because the turbine buckets expanded due to excessive heat and cut into the outer shroud ring housing. This made a very loud scraping noise and also began to deform the outer housing. The en4ne was immediately shut dom. It was then taken from the stand) dismantled and sent to the disassembly section and scheduled for various design changes. 4. During the time this powerplant was in disease:ably a new policy change was issued Fran higher authority to give this project up and concentrate on the 003C. Also..;during this time the design department was working on the BMW-028 project and the JUM0-022 and seemed pre-occupied. This was in the winter of 1947-4%. 50X1-HUM the BMW-018 Idesign features were adapted to Object A-022, 50X1-HUM B. Specifications 1, The Ingr-i01.8 was a turbojet engine with a 12-stage axial compressor and a single annular combustion chamber. It had a 3-stage turbine fabriciated of steel and hollow alloyed guide vanes that were air-cooled in the 1st and 2nd stages. The first stage turbine rotor was hollow steel and was air-cooled, while the second and third stage had root-cooled solid steel buckets. The exhaust nozzle was variable and electrically operated by an automatic control. The general construction pattern of this engine was the direction in which all later and more successful engines went and is described in more detail later in Object A-022. The BMW was never run to maximum paver output but was said to have well over 3000 kg of thrust. 011 THIS DOCUMENT CONTAINS INFORMATION AFFEETINH11111 NATIONAL, 00 t tvii or i It UNI1LI) SIAFLLi WITHIN THE MI ANING 01 11H lliPIONAGE AC ISO II S.C.- 3) AND a AS AMENDED.

The same type checks as previously completed were accomplished here also. But in addition, there were checks on the waterbrake and couplings. (The waterbrake was new and needed com- putation checker also.) F. Firing up the Burners 1. At the completion of the 2800 RPM break in.tests and when all seemed to be well and ready the combustion chambers were fired up. This was at 800 RPMfe and with gasoline having about a 5% 'oil addition. The fuel pressure used for this start was supplied by a special electric pump of 2 stn. Miring these first rune there was considerable difficulty in ignition. /t was thought that an improper mixture of fuelo-mir was the cause, There followed, of course, changes in the ignition plug types, fuel pressure changes, and later, changes in the fuel jet nozzle types. Then some starts from 430 to 800 RAM's were tried. Various combinations were tried and the best combination was found to bet a. At 400 Mite the ignition plugs came on b. At 800-1100 the fuel was turned at' into the burners 2. During the first series of start toots, "hot starts" were frequently ex- perienced (7004006 measured at T6). Whenever the engine west peyond 700-400" C they would nearly always shut the engine dawn and inspect it. Sanitises temperatures would go to 1000? C and this would always be cause for a shut down. Later normal starts were being made at WO? C. 3. Good starts were taken up to 3500 RFMIs. The starter motor was then out out and the engine left to idle on its me All measurements were taken here. These idling runs were sometimes up to an hour, and then again sometimes only 10 minutes. When the engine VAS shut down again, sometimes it was taken to disassembly and cheeked for turbine, compressor and in- ternal material failure. /his type of testing extended over a period of about 2 to 3 months. They were also having difficulty with the waterbrake coupling (Dwg. No. 5 ). The waterbrake mounting, the pendulum motor, and the engine were all mounted on separate stands. The tolerances were too difficult to maintain and considerable instability in proper alignment was plagueing the suooese of this series of tests. The turbine break-in period was included in this 3500 RPM test.

Here they found that the tailpipe temperature rose dorrespondingly to the RPhits, but by too large of increments. At the 6500 RPMts they started experimenting with the hydraulically controlled air bleed valves. These were remotely controlled from control room. They tried various settings to determine how many needed and how much to open, and at what RPIlts necessary to maintain a desired temperature. 2. The correct amount was done finally by a Characteristic curve of the compressor which predicted that at a setting of 6500 RPMts there would be a compressor stall and a small vibration would take place within the compressor. This would result in a consequent rise in tailpipe temperer- tures. this proved out in practice as was predicted in theory. In addition, though, in practice it was noted that if the holes closed too soon a stall also occurred. 50X1-HUM 3. They tried stopping up the air holes used for cooling the turbine in engine #104 which was in preparation for Object 11-022. The specific fuel consumption dropped noticeably but the temperatures rose too rapidly. They tried various systems here until they reached the compromise they wanted. Engine #104 also was run at an overload condition for 50 hours; small changes were always being made during construction on the "next to be run" powerplant. Later they all had more power. H. Plotting the Characteristic Curve 1. 50X1 -HUM The next series of testa were to plot a characteristic curve for engine. Under 3500 RPMts it was difficult to maintain a constant and so the plot- ting was done from 3500 RPUte up. This was then considered idling, burners would stay lit back to 2000 RPMte, but then the tail- pipe temperature starts to rise rapidly and shuddering would take place. This was from a compressor stall, but it also would sometimes flame out here without a stall. 2. At each 200 RPM increments from idling to 7700 RPM (maximum), the various engineering groups took their respective readings to plot against their theoretical curves. These tests were re-run, and each time, with in- creased loads. This continued until the engineering group considered everything satisfactory. This testing period consumed about 2-1/2 to 3 months. During this time, one powerplant was assembled with gear reduc- tion housing and propeller. The propeller pitch change was operated by a manual hydraulic control, remotely from the control room. 3. After a curve test on each engine produced, the engine is either selected for flight testa or it is used for endurance testing. When it is te be flight tested, it receives an additional 5 hours run for an endurance test, It is then pickled and shipped. During this curve testing phase, some engines were purposely overloaded and over-run to determine some of the ultimate limits. Ultimate temperature limits were also determined by cutting holes into turbine bucket roots and filling with various metals of knowh melting temperature points. Sometimes holes were drilled in the turbine wheel between the "X-mas Tree" bucket retainers.

At various times instruments were re-checked and re-calibrated and at the end of each calibration run the measuring instruments were always re-checked and re-calibrated.

All endurance tests were run with propellers, with the exception of a few that were to be run with overloading conditions. These tests were run (minus propellers) on the waterbrake test stand with a controlled amount of overloading. The endurance tests were the same in principle as the 003C in that there were similar types of inspections prior to running and the five-hour phases were run in the same manner. However, in the A-022, all phases were worked out in more detail and closer tolerances were held, And while the Official State Test of the 003C was only 50 hours, the A-02 was 100 hours. 2. After 5 hours of testini; (Phase I) the prop pitch and feathering was tested. In peneral, there were more external loads put on this engine than on the 603C such as generators, compressor, hydraulic pump loads, etc. There was also an air bleed from the compressor section that was used for cabin pressurization. During each 5 hour stage of testing, this air was analyzed for its gaseous contents. The greatest difference in the A-022 endurance tests was that no output was measured on the propeller stand. These newly constructed test stands for props were erected differently and a groove was cut into the flooring wide enough for the blade tips to pass. The blade tips passed below the horizontal level of the flooring. NOTE. i DOC -Mt ct et. ? iI AM- 12 II ???? ? ? -II t ? INIL..11.t ? MAlNiNitIt ("TING THE NM IONAt OFFEN'yl OF THE.

The starting motor utilized was the TS-1 also known in the project listings as "Skject_00 2. There were start tests to test the endurance of the TS-10 The first phase consisted of 150 starts, which later was considered a standard. There was one special test that ran to 200 starts. During these tests they would sometimes let the engine set until cooled down to the winter's temperature to simulate settin7. over night, Then re-starting was accomplished. These tests took weeks to rune 3. In cold weather tests kerosene was mixed with oil at various percents to determine how much dilution was necessary in utilizing the 15-1 for start- ing. This was done at -30? C to -40? C temperatures, and up to 75% kero- sene was tried. All regulators and accessories using oil were diluted with kerosene in the same manner in order to insure fluid conditions and not have failures of an important regulator control due to congealing of the oil. L The starting procedures were as follows: a. An electric motor was started by a switch in the control room. This started the TS-1 gas turbine starter engine which then accelerated to maximum RPM. Starting igniter plugs were also in this circuit. b. Th.? maximum RPM's acceleration is timed, and when reached, an electric timer relay shoots an oil pressure that hydraulically couples the TS-1 to the engine for starting torque rotation. c. At hn0-500 RPM's the "stop-start" sensitizer sends an impulse to the igniter relay which in turn starts the igniter plugs? d. At 800 RPM's the operator in the control room starts handling the throttle to keep fuel pressure correct and thus tailpipe temperatures within limits. e. When the powerplant has reached 2000 RPM's the "stop-start" sensitize actuates an oil pressure that ties into the accessory section idler gears, and thus hydraulically disengages the 15-1. f0 At the same time the 1S-1 is disengagedp'an oil hydraulic impulse is sent to a relay that turns off the fuel and thus shuts down the TS-14 The turboprop engine is then accelerating on its awn. ge Also, at 2000 RPM's a starting sequence light in the control room that is tied into the TS-1 relay circuit would go "out". ho A second light tied into the sensitizer relay circuit would go out also. i0 Then the operator would be free to increase the RPM's by the throttle control to 3500 which was considered idling.

During the experimental phase of testing, there were different types of blades tested. For same of these tests there were thermodynamic instruments set at different planes on the blades. This was accomplished by cutting channels into the solid aluminum blades. These channels were then filled with a plastic substance with thermo?elements running between the plastic and aluminum. On later blades (which were wider) there was a collector ring at the tip of each blade for all these thermal elements and then this was funneled up the back to a master distributing ring, (Note: probably meant strain gauges). 50X 50X1-HUM 2.

This secondary piston) which was within the fuel regulator, was in turn activated and regulated fuel flow. 5ource knows nothing of inside of fie' regulator (KTA). (later, there was in instrument called "Temperature Measuring Instru? ment", which was on the right side of all engines. This instrument had a metal covered shielded cable leadin.: to the regulator (Km) and having a male plug. The cable was about 1 cm in diameter and carried electrical wiring. There were always electric wiring leads coming from Ti and 120 but only for 6 months at DS. (A pressure line also led to the (Mm) from behind the last (1)4th) stage of the campressir.) A b. The propeller regulator was tied directly to the fuel regulator by an oil pressure line. Its operation was dependent on an oil pressure impulse from the fuel regulator. This pressure was at 20-25 atu maximum. c. The governor itself incorporated a booster pump within itself that operated the blade pitch angle changes. This was from the signal of the fuel regulator pressuresj (20-25) atii. There were three pumps in all for the propeller pitch change: (1) The normal pitch angle pump (explained above) (2) A separate system pump for the reverse pitch control (3) A separate system pump for feathering. d. The only control of the RPM's was through the fuel regulator itself. When the throttle is advanced, the pitch an2;le is flattened out to Increased RPM's by an impulse sent from the regulator. e. The fly weights within the governor itself, and which operates the pitch angle change also, then have only two functions: (1) To maintain a constant RPM's in various densities (2) Prohibit an over speed condition during maximum RPM's and in? flight pitch changes and during engine acceleration. won. us DOCumt NT t OS I AINS INFORMATION Ar!

At first the tachometer was diroctly connected to the engine by a driveshaf t that operated a set of contact points which opened and closed. A 2/LV D.C. current was fed into this counter and by a return line passed through a junction box that also utilized a 220V A.C. power fed into it from the city. This junction bout also contained a counter and a stop watch. To read the RPM,s0 a button is pushed and the counter window is zero,d. Then when the button is released the counter system runs for exactly one minute. The number of times the circuit breaker !.s actuated is recorded thus giving RPM'S. Note : A curve for this apparatus also had to be calibrated for the Calibration and Official State Tests to compensate for pulse changes i n the ci ty s 5)-cycle AC current). Later an aircraft type tachometer system was used. This system in- corporated two separate aircraft type tachometers. (Note: A curve plot was also made to check the accuracy of these tachometers during calibration and official state tests. A hand strobe-light system was also used for counting the RPM'S). 2. Turbine Failures: a. In the testing of the A-022 and AF-2 there was one failure where the wheel came off. (AF-2 was a version of the A-022 before 100 Series and only one was built. It failed at turbine). b. There were about two other failures: one where two. stages of turbines flew off and one where a single stage disentigrated. c. Many times blade failures occurred and blades flew off. Most of these failures were where the blades broke off at the roots. 3. Combustion chambers up to engine #18 did not incorporate the short combus- tion chambers. Engine #25 did but these ire.Tre only for special tests and were not continued in production. No short burner engines were flight tested. Li. Graphite seal rings came into production engines only after engines in the 100 series.

OBJECT M-022 A. General 1. Object !!-022 was a powerplant made up of two A-022's and coupled together by a reduction gear housing. In the 14-022 configuration two A-022 engines were coupled to a dual leiblade contr50X1-HUM rotating propeller a coMbination of planetary and spur gears (Planetengetriebe und Strinvardergetriebe). 50X1-HUM 2, For Object M-022 a newer test stand was built. This was also used for Official State Tests. It was 10m x 10m inside dimensions. The M-022 never underwent the Official State Tests but the stand was later used for Object "K". There were more test stands for the 14-022 built at Zavod II. These were shipped out disassembled along with a full set of drawings fez' each stand. There were also three stands left there at Zavod II for testing Object "Ir and later all of these stands were re-built into "Object K" test stands. 50X1-HUM 3, somewhere near went with some craft airfield near MOSCOW. an aircraft had crashed near MOSCOW withean Object 'WI powerplan the reason for the crash was some fault with the mountings. and "" 50X1-HUM the engine had torn itself out of the mounts. there was much talk of a Special Commission from the Ministry for Air. They did visit Zavod II and came only to check the dampers and suspension mounting of the engine test stands on Object M-022. As this happened the OTK men had to rush around the plant and stamp ore- inspection dates on all parts making up the suspension units. 50X1-HUM 50X1-HUM the Object 14-022 engine had been flight tested MOSCOW.

Then the plane- tary gears that rotated about the spur gear had the same thickness but were about 150 mm in diameter. The gear teeth were straight. (However, angle teeth gears were tried also but not for long.) 50X1-HUM could not give any information about gear reduction but gave a hazy version of the propeller diameter. This was About 6.E meters.

Both engines were right hand rotation and the rear propeller was also right hand rotation. The contra-rotating arrangement was accomplished by a50X1-HUM hollow shaft. One powerplant was to one propeller and the second was to the other. 2. On earlier mounting systems although when one engine would be partly or fully shut down that engine would not be disengaged but no longer would be engaged and other engine swung both props. 50X1-HUM 36 The propeller was eight blade contra-rotating with the first croup having rounded tips and a slight taper from the shank toward the tip. Those were later cut off to square tips. Then newer blades came with square tips. These were very wide blades and these props were later used on Object "K". L. There was one ,overnor mounted on each engine for each propeller. The fuel regulator for each engine was connected to the governor for that propeller and operated the blade pitch angle booster pump within that governor. There was also an equalizing line connecting both lines from regulator to governor. This was tied in to each pulse line to the governo at the governor inlet. Alongside the fuel regulator was a control box that had a mechanical linkage to the regulator. An oil hydraulic line ran from this box to the governor in parallel to the line from the fuel regu- lator. ( 5. (Note: Here there were two lines coming into each governor but only the lines from the regulator had an equalizing line.) 50X1-HUM The small differences in RPMIs that would arise in each engine would be compensated for in the propeller pitch angle change by this equalizing line and the separate control box. The box was know ctric ulse Producing control and operated from a 24V current. if the propeller governor lines were criss-cross not too much effect was noticeable, there were some small differences but mostly in the test readings. Although the ent:ines ran almost the same, the manometer readings in the control room were all off. 50X1-HUM 6. The feathering was a separate system. A single pump was mounted on each engine, one for each individual propeller. Later on there was a_single pump designed and built to feather both sections of the propellor'. This was mounted independent of the engines and operated by an electric motor driven hydraulic pump. A separate tank was incorporated in parallel to the oil system. This was so that the feathering pump would not be putting too much drain on the normal oil system. D. Testin& 1. Testing of Object M-022 was much the same as the Object A-022. In the M-022 the fuel regulators were coupled by mechanical linkage to a single throttle. A single oil circulation and cooling system serviced both en- gines.
