A P-I01 FLIGHT TEST
TE.E.
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.

MODIFICATIONS AND GROUND TESTS
Transmitter and Transmitter Servo
Servo lock--up problems were encountered with transmitter 001.
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.

Antenna
An antenna pressure failure on flight 177 caused a pressure
window burn-out. 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.

B FIELD FUGI.T TEST
Understanding that the SOAR) radar may be tested in the
western area this fall, a proposal is being prepared for the
reactivation of the Field Flight Test. 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

altitude line. 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

gations.

t Polyimide High temperature binder solutions have
been evaluated. 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.

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. There is a low margin between
the chart value melting point of the solder 314?) and the m:a.xlw=

which often requires resoldering. 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.

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.

An Omega D6 Englarger has been received and installed in
the darkroom with the Log-E-Tronic dodging printer.. 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

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. The aspect ratio is very
close to 1. to 1,
