Six radar flights were flown in August, five of wh produced useful data. Three of these missions were flown over Baltimore Harbor- to obtain target signature data on a merchant ship.. Specific information on all six flights is tabulated in Appendix A. Aircraft rework performed by an Air Force team fry Hill APB, Utah, was completed and an aircraft functional check flight on August 3. This rework satisfies the current repair requirements in lieu of IRAN. An, overboost on the right hand engine in after-burner operation above 30#000 feet altitude has prevented super-sonic flights for almost five months. After many unsuccessful parts replacements and tests, the right engine was replaced this month. The functional check flight on August 18 showed satisfactory after burner operation. A Tech Order concerning inspection of after-burner sections of all F-101 engines was received and complied with after the engine change.

Both the original set of servo printed circuit boards and the replacement set were defective. Satisfactory operation was obtained with the third set of boards, filtering was added to improve per- formance. The two defective sets are being repaired. Receiver and Frequency Generator Video noise level decreased during the course of flight An intermittently open inductor in the Frequency Generator caused a 3 db decrease in the Video local oscillator voltage. addition, a defective transistor was found in the Frequency Generator circuit for the DFT local oscillator. This undoubtedly caused the loose; DFT control of the past few flights and will be checked further on the next f l i.gh orde ation to the electronic package, recorder 007 was installed in the F-101 prior to flight 1=,91. Operation with type 2401 film (mylar, 4 nil thick base) was satisfactory. Since the supply of type 2401 film was exhausted type 5401 (acetate, 512 mil thick base) was substituted. Normal film transport could not be obtained. Recorder 005 worked properly with type 5k01 and was reinstalled on the aircraft to minimize system down-time.. Recorder 007 was returned to the lab for repair.

The antenna was repairedby replacing two modules and sealing leaks In the manifold., Linear Motion Ccpensation Ground tests indicated good Linear Notion Compensation system operation Network null voltage, resonant time, and transient response were all satisfactory. A new flight procedure for the Linear Motion Compensation was used on flight 182. This procedure was: 1. start erection of roll table 5 seconds later, connect a:cceler, ter integrating network 0 5 seconds later, switch roll table to Reset, which refines the roll table position with the accelerometer mounted on the table 20 seconds later, unground the integrator input and switch network gain from low to high 25 seconds later, with a total elapsed time of 55 seconds, roll table is returned from Reset to Normal, which connects accelerometer to the network. The radar operator was satisfied with the operation, but film and instrumentation data have not been analyzed. KA- Camera After repair and adjustment of the KA-45A camera at the manu- facturer, the camera was re-installed In the aircraft. Initial ground checks were acceptable. However, on flight 178 the film transport ed. Operation was satisfactory on 179 but a jam occurred again on flight 180. Cause of the failures is being Investigated.

First flight is tentatively set for 1 November 1965. C SYSTEM Two technical memorandums were recently released. STM-170 ', ed "Pulse Narrowing 'Investigation`* summarizes the narrow pulse work on the transmitter, including the effect on overa system resolution. "Effect of Temperature and Humidity on Aerial Filmst*, STM-171, reviews the general environmental effects on aerial films as they are used in the SOARD recorder. tions to the second electronic package are now complete. Work on the last package Is well underway and, when complete, wil allow full interchange of recorders or their sub-assemblies AUTOMATIC GAIN CONTROL fiver gain has sometimes varied between the pre-flight checks and the mapping runs, because of changes in voltage, temperature, or component tube gains. The recorded signal level significant effect on the quality of map, causing changes in target signatures. Automatic gain control AOCO has been proposed as a minor modification to the F-lO1 system to provide more uniform gain. Noise is used as an indicator of receiver gain, as shown In the block diagram of Figure 1. The noise is gated during the no- 1 period between the time of the transmitted pulse and the AL HANDLING Sanitized Copy Approved for Release 2010/12/09: CIA-RDP67B00657R000200210009-4 Par Anp i co Sanitized Copy Approved for Release 2010/12/09: CIA-RDP67B00657R000200210009-4 I.

The gate width is adjustable to acoomodate various altitudes, with 30 microseconds being sufficient for 20,000 and 4o,ooa feet. When the "second-time-around-return" is used on the Field Flight Test (4 kc recorder operation), the AOC as mechanized is not usable. The gated noise is detected and sensed by a differential amplifier. The differential output is isolated with a common emitter amplifier, which matches the impedance to the grid circuit of the I.F. amplifier. The differential amplifier tends to maintain its input at a fixed 3 volt level by adjusting the L.F. gain:. The output noise level of the Video Amplifier is set by adjusting the gain of the first amplifier in the AGC loop. The proposed AGC scheme has proved to be feasible in a laboratory set-up. Work is underway to adapt this circuit to a flyable breadboard for the F-101. After test flights with the AG its performance will be evaluated to determine it additional units are desired for the deliverable systems. Little modification is required to incorporate the ACC in the present system. The R.F. failure connector on the Video Amplifier can be used to provide the input signal with no additional loading on. the CRT grid. A connector on the I.F. amplifier is already avat3.able for the gain control. ANTENNA Study of the bonding problem at Westinghouse Research Labs is complete, except for the writing of a report on their investi- gations.

Type PI-1101 failed to hold air at room temper ature. P1-12E produced a good bond, but no additiona are planned since this material is similar to the 10 resin ady tested and the reccmmended cure temperature exceeds av, able oven temperatures. Tests showed no significant advantage of cleaning with. Freon as canpared to Trichloroethylene now used. No chemical deterioration of bond was noted with either material hour soak at 5500 F. 30 The most significant result was that sticks on which mylar tape was not used to mask the slots had no areas of poor adhesion. It is felt that the adhesive on the my1ar tape previously used has caused the spots of poor adhesion. With this problem corrected with a change in tape, repair of the antennas can continue. Using the resin and fabric from the same batches as will be used for the final units, eight sticks were bonded In accordance with the latest revision to the process specification. All eight irks held air at room temperature. Three of the sticks are being tested at 550?F and 30 psi& pressure. By, the end of August, the three were holding pressure after 100 hours testing. The array sticks are presently joined to the manifold with a 95% le,14-5% indium solder as a pressure seal covered with an el.ectro- ormed wall for mechanical strength.

Higher temperature solders are improvement. A high temperature local heating method, such as electron beam welding, may be more desirable. This process would perform the functions of the solder, etching, and electroforming.. Disassembly and repair would be more difficult. Additional in- vestigation is underway to select the best procedure. SPARES No Items were added to either the system or ground support equipment spares.

E CQRR ATOR OPERATION Flight 182 was correlated on August 31, the first high altitude flight since April. Data was good, but the near range was very light. It appears that alignment was incorrect on the .050 inch upper slit recently added. A test will be made with various positions of the slit.

Various films were tested with the dodging printer. Type 8430, an aerial duplicating film, was too slow and had insufficient dynamic range. Although 5427 has better dynamic range than 8430, it is still slow. Kodalith Ortho Type 3 proved to lack the tonal qualities needed Panatomic X was found to be the best, with sufficient speed and resolution. The Panata is X is developed by hand in DK50 diluted l to 1. Resolution and grain structure are fine enough using BBL 50. Contrast is higher and development times shorter than for a fine grain developer such as Microdol-X, exposure for an intermediate positive appears to be one p greater than for a normal print at maximum dodging. This intermediate positive is then dodged to make a negative for final paper prints. The diverger for the laser was received for the Beta Correlator. Since the laser was not centered with respect to the diverger mount., the beam was driven off at about a 100 angle. was then. decided to use the microscope objective in conjunction with the pin-hole from the diverger. This. provided a cone with few of the dark rings inherent with a larger pinhole. The spare optics for the dynamic Correlator just received from Xtek were then set up in the Detail Correlator. A six inch enlarging lens is used to bring the output azimuth image to the same separation as on the input film.
