The original design for the JUMO 022 turbo prop engine was started in the early part of 1948 by order of the Soviet War ,Ministry. Prior to the order, some theoretical work was per- formed under the direction of Dr __V__o__g~t__s__. The first engine was fabricated by the fall of 1949 andtotal of ten were com- pleted by the time of my departure in September 1950. Each engine was numbered,,one through ten consecutively. The first three engines were designed as the 022 and the engines from four through ten were d.esignat-ed, as 022A. The variations in the ten engines were those found necessary through tests. All engines were built at Zavod No 2, including the standard hard- ware-such as nuts and bolts, normally supply items. Engine models that were contemplated but never built were the 022C and D. The 022C was planned by the design department and worked out by Dienhardt, Chief of the Compressor Group, It was to have only eight stages. The 022D was planned by the Experimental Department. 50X1-HUM 5, an 022F engine was In the stage of construction, This was to be an improved model and its 50X1-HUM objective was to achieve a specific fuel consumption of less than 300 hr. The specifications or the 0 2F called f'or a maximum power of 5000 hp with a specific fuel consumption of 320 g/hp/hr, ~ngines numbered eight and nine were set aside or a state acceptance run Leading Particulars and Performance: } 7.

Before assembly of the rotor, each wheel was balanced separately by drilling away material, A final balance was made on assembly. There were no particular pro- blems involved in assembly and balance, The"rotor blades were, made by stamping and final machining. The blades of the first six or eight stages were made of an aluminum alloy called Pantal, while the blades mf the last stages were made of a steel similar to 3OX rCA . The pr . files of the rotor blad s were taken from th Go ppingen series 50X1-HUM Herr Steudel, an still in Kuybyshev, knew the composition of the 50X1-HUM material used since he was head of the materials laboratory. The compressor rotor was supported in the front by means of a roller bearing that permitted a 3 -.5 mm axial movement of the rotor. The rotor shaft was attached to the propeller reduction gearing by means of a splined joint. The rear of the compressor rotor was supported by a radial bearing and was attached to the turbine shaft by means of a splined joint. In addition a through bolt from the turbine assembly was fixed to the compressor rotor, flee Enclosure (D) showing the turbine Assembly. The rear compressor bearing carried an axial thrust load of 1000kg as a result of the difference in the axial forces on the turbine and the compressors. 11. Two air release valves not shown on Enclosure (A7 were located at the fifth an sixth stages of the stator rings, 'Surge and stall difficulties were encountered within the compressor at low speed of the engine. These valves relieved the pressure build-up until the engine surpassed the 'critical speed. The power absorbed by the compressor is not known 50X1-HUM Turbine Assembly: 12.

The outer casing of the turbine consisted of two solid rings that bolted to each other and in turn bolted,to the com- bustion casing fors support, . They, were made of steel material designated by the Soviets as 9A/71. The second and third stage stator blades were welded to the rings and could only be removed with the individual rings,. The three turbine wheels butted each other at the hub and in turn were anchored to the turbine shaft by six through stud bolts that screwed into the turbine shaft., Two look nuts on each stud were used to pull the wheels into place and secure them. ?The'individual blades were attached to the wheels by means of a conventional fir cone profile. At first the blades were pressed into the rotor wheels with a drive fit, Later they were inserted with a sliding fit. When blade shifting occurred, safety plates were added. The turbine shaft was supported by a roller . bearing and the shaft extended through the combustion assembly to connect to the compressor rotor by means of a splined joint, .Two adjustable retaining nuts at the splined end of the shaft SECRET .

An axial movement of the wheels was used to set the desired clearance between the turbine rotor blades and the tapered walls,. Axial movement of the turbine' wheel assembly and shaft with respect to compressor was pre- vented by a ,single through bolt that extended through the center of the turbine wheels and shaft and screwed into the compressor rotor, the axial load of the turbine wheels was approximately 12,000 kg. This load was transmitted by the through bolt to the compressor rotor that produced a compensating load of 8000 kg, The 4000 kg difference was taken up by the radial thrust bearing supporting the,compres.sor 50X1-HUM 14. The 022F which was in the design stage and partially con- structed was to incorporate changes in the turbine assembly [ss shown on Enclosure (F. These changes were as follows:; The abrupt angles of the turbine casing walls were. eliminated and a smooth flow transition provided be- tween stages, The outer wall casing flanges were out down by about 5 mm, to reduce weight, a, The flanges were reworked so that the hexagon nuts were locked in place by the flange itself, d. The flange bolts were reworked as sheer bolts as well and tension bolts so that stress and strain from temperature differences around the casing could be equalized, e, Due to pressure losses between turbine wheel stages, a flange was added to the downstream side of the rotor wheels of the first and second stages. In addition, a copper or bronze ring was added to the inner stator rings of the second and third stages. The copper or bronze ring was so placed that an air seal was formed this innovation was to be used on engines ,or 50X1-HUM the State Acceptance Test. Reinforcing rings were added to the turbine casing to prevent warpage. Design Procedure on Turbine Assembly: 15. The initial design and layout of the 022 engine was based on the specification set down by the thermodynamic department. From the specifications the thermodynamic department received,,,. calculations Were made which established the condition entering and leaving the..compressor, combustion chambers, turbine and exhaust nozzle, The, original specifications that started the project called for a turbo prop engine that would produce; 4,500 HP with a residual thrust of 90 kg. The take-off speed would be 7,700 rpm, and the airflow through the compressor would be 29 kg/sec., The calorific valve of the fuel to be used would be 10,.000 k cal/kg. The engine was to have a maximum diameter of 1,050'mm, The resulting data which the turbine design group received from the thermodynamic department and on which the.-initial design for the turbine assembly was based was as follows for maximum powero SECRET Sanitized Copy Approved for Release 2011/02/25: CIA-RDP82-00457RO12900210007-3 Sanitized Copy Approved for Release 2011/02/25: CIA-RDP82-00457RO12900210007-3 SECRET/SECURITY INFORMATION 7 50X1-HUM t4 - Static temp. at turbine entrance 8500 Celsius P4 - Static press. at turbine entrance - 4.8 atmospheres' 04 - Static velocity at turbine entrance - 120 m/ssee P6 - Static press.at turbine exit - Atmospheric C6 - Static velocity at turbine exit - 200 11/see The turbine outlet conditions were based. on the assumption that .an adiabatic turbine efficiency 77,.c 7-=.85 .

With experimental values available for the contraction factor of single stages, efficiencies of guide bladesq and rotor blades X , and angular deviations of flow leaving the blades E , and with a fixed maximum diameter given, the preliminary design of the turbine flow channel, stages, etc, was aecom- plisshed by calculating the flow at the mean diameter of the channel. The turbine was designed as a reaction turbine with the degree of reaction increasing from the first to the third stage. At every point of the turbine, the condition that the design measurements times the prevailing gas condition be equal to the gas weight had to be fulfilled. -That is, Darcy r C' 9 where D - diameter, 1 - length,Y ='ratio of specific heat, and C ='velocity, Later, more exact calculations took into con- sideration the.ratio of the flow at the tip and root of the blades, For the guide vane rings the following was valid: At foot ci _ YM ) Z401, X At tip Ca = Cm Y. 2ices +'t where r f radius andQ( ? angle between direction of fluid velocity and peripheral-velocity. For the stator assembly LQ was assumed as .97 and the contraction f.ACtor.. ( .. was between .88 and .92 a b .88 - .92 17. At first, all guide blades of the three stages were constructed with the same profile. The thickness of the trailing edge out .off $ was 2.5 mm. To reduce outlet losses, the trailing edge of the second and third stage stator blades was reduced to 32 ^ S 1.5 mm,. However, Sl was maintained at 2.5 mm to prevent cracks from appearing, The cracks caused by heat appeared at the tip and progressed from the trailing edge to the leading edge of the blades. The trailing edge from root to tip was maintained constant for the stator blades. The trailing edge of the rotor blades was tapered from S - 2 mm at the root to S = .5 mm at the tip. At first rotor blades of the second stage were used to provide blades for the first stage by reducing their length. Later the first stage rotor blades were fabricated separately so as to reduce their weight. The area ratio of the; root profile to the tip profile was of'= .' the magnitude of 1:3 to 1:4,. The contraction factor for the rotor blades.was .85 at the root and .97 at the tip. 18.. The frictional flow losses of the rotor blades resulted in )4- fluctuating between .93 and .955.

Angular deviations E were not considered for the stator blades until 1949. A deviation of 20 was then used.

When the design work was performed on the 022F,.past experience was utilizdd in an attempt to produce a more efficient turbine unit. An attempt was made to avoid stage-jumping and to match the flow well between stages. Wall friction and zones of turbulence, which could by that time be determined, were considered. Tests made with adjustable stator blades pro- duced valuable information on the ideal angle settings that could be used. The final outcome was bound to be an improved turbine unit for the 022F. In regard to the 022F, a difference of opinion existed between.Dr Cordes and Kuznetsov , Chief of the Design Unit. Dr Cordes beTieve?d that or the rotor and stator blades a larger ratio of t/i (t ? grid division and 1 = blade chord) should be used. He wanted to achieve a better flow friction factor with less blades and wide grid divisions and obtain the required efficiency through a larger angle deviation. On the other hand,K etsov believed that the flow should be well led and this could be achieved best by narrower grid divisions, 23. In 1949 a project was started'to design an 022 turbine assembly composed of two stages. To do. this it was found necessary to assume flow conditions above critical,.M greater than 1., at various points within the rotor and stator stages. Since there was not enough available experience in this field, the project was given up for the time being. Enclosures (R) and (L) are the basic velocity diagrams for the two-stage projeetj Fabrication of the Turbine Rotor Blades: 2*. The turbine rotor blades for the JDMO 012 and the early 022 could only be made by a series of turning, milling, planing, and hand operations. Amilling cutter in the shape of a truncated cone with a radii of 11"4. and Y,. was fed in a manner perpendicular to the blade base profile. The cutter was fed several times. to approximate the shape of the profile, Finally the blade was hand-filed to match a pattern n.nd polished. This was a time-consuming operation and limited the form that the blade could take. ee Enclosure (M), Sketch No 1j Later a Sanitized Copy Approved for Release 2011/02/25: CIA-RDP82-00457RO12900210007-3 Sanitized Copy Approved for Release 2011/02/25: CIA-RDP82-00457RO12900210007-3 SECRET/SECURITY INFORMATION - 9 50X1-HUM completely new method of fabrication of blades was developed in the workshops. at Zavod No 2. The method permitted a blade to be produced with any desired form necessary to obtain success- ful flow conditions. Dr Bredendieck, still in the USSR, de- veloped the method for the nn'l`er side of the blade. With his method, the entire inner side of the blade from leading edge to trailing edge was formed in one operation, He proposed using a cylindrical face milling cutter with a radiusT . ,`ee Sketches 2 and 3 of Enclosure (M),7 The blank-blade was mounted horizontally with inner side up on a balancer set at some desired drift correction "a". The predetermined contours of the root and tip profiles were projected and duplicates or copy curves were worked up as guide tracks. With the cutter in a fixed position, the balancer was fed horizontally and vertically following the contoured guide tracks. The single operation for the inner side which produced a blade requiring a minimum of hand work took approximately 45 minutes. A later, innovation provided for a balancer that could be rotated and thus vary the degree of drift "a" during the process. The process not only provided the desired contours over the entire inner blade surface but also permitted the center of gravity of the individual profiles to be located so that movements resulting from centrifugal and gas forces were a minimum. The system used for milling the outer contour was proposed by Mr Singer, one 50X1-HUM of thirty engineers to the USSR again, a copy milling machine was used and several operations 50X1-HUM were involved. result of fabrication were not excessive.

However, during the drive to reduce the overall engine weight, the outer casings were eliminated and the. exhaust nozzle shown ~Fn En- closure (0),7 was developed.

The whole unit was promising but it was 50X1-HUM dropped by the Germans because it was more com or able to do so. Should any difficulties have arisen, it would have meant trouble with the Soviets. One way of avoiding trouble was to refrain from having new ideas.. One of the peculiarities of this engine was the vibration set up on the last stage of the rotor blades, if the leading edge of the six support struts of the nozzle was located within 120 mm of.the trailing edge of the blades. The vibration would cause severe cracks in the rotor blades.. 27,, The velocity entering the exhaust nozzles of the A engine was approximately 200 m/sec and leaving was 195 rn/sec?

The test was discontinued and not completed, The German per- sonnel were of the opinion that the Soviets did-this purposely in order to prevent a successful test and thus avoid paying the Germans a promised bonus. They were told that the.engine was not'a success and that work would not continue, since there was no plane that could use the JUMO 012.

The group leader was responsible for the accuracy of all details within the group, The construction office had a fixed budget which paid for-little errors in construction. Major mistakes in drawings,. which led to faulty fabrication,'- had to be paid for by the responsible group leader (sometimes one-third of one's monthly salary). All drawings had to be submitted to the group leader.. The group leader in turn had to submit all drawings to the de- partment chief and his Soviet deputy. Afterwards, all drawings were channeled to the norm control office, the chief metallur- gist, and the chief for work planning or their deputies. The drawings were then submitted to the chief construction eng-' ineer and his deputy for approval. Only when all these offices had no further objections against the design ,and the fabri- cation procedure and each chief had signed approval could the group leader dare to present the drawings to the chief tech- nical designer or to his deputy. And only after their signa- ture were the workshops allowed to work with these drawings, The complexities of the organization are hard to imagine. However, the greatest difficulty for the group leaders was the fact that all work and running around had to be accomplished in an incredibly short time. In many oases, the deadlines were in practice impossible. Furthermore, all necessary work in the sheet metal shop, turning section, milling shop, assembly and test stand, had to be co-supervised by the group leader because he was also responsible in the event of failures. Generally speaking, the employee in the USSR had many duties but no rights. Some of the leading personnel were as follows:1' Kusn (Soviet) .- Chief Technical Designer.
