antl> x —_ FLATHEAD) Project 5.5 - In-Flight Participation of F-S4F Aircraft - lst Lt. R. F, Mitchell Objective Waiter (Capabilities F-48F) - This participation was an attempt to determine the capability of the F-S4F aircraft by subjecting it to both thermal and symmetric blast loads. Barley (Sideloads F-84F) - The objective of this participation was to study the dynamic response of fighter structures to anti-symmetric blast loads, Instrumentation « Waiter - 100 data channels were available to record moment, shear, and torsion loads; thermal strain; temperature rise; overpressure; accel~ erations; and aircraft altitude. that failed. Of these channels, there were 2 channels In addition, a flap camera and an NRDL camera were inoperat= ive. Barley - Out of the 100 data channels available to record essentially the same information as above, there were 3 channels that failed. Aircraft Position in Space Waiter - At time zero, the aircraft was flying at an absolute altitude of 21,000 feet on an inbound heading of 1259, was -740 feet with zero offset. The horizontal range The shock arrival position (at H¢18.99 sec) was 21,000 feet altitude and 10,900 feet horizontal range. The true air~ speed was maintained at 800 ft/sec. Barley - At time zero, the aircraft was flying at an absolute altitude of 18,000 feet on an inbound heading of 0979, The horizontal range and off- set were -22,400 feet and 34,400 feet respectively, .
