— MARRcs: Project 5.5 - In-Flight Participation of an F-84F Aircraft - Lt J.A. Sabatella OBJECTIVE Waiter (Capabilities F-84F) - This participation was an attempt to determine tke capability of tre F-84F 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; accelerations, overpressure, temperature, thermal strain, and aircraft attitude. Out of these channels there were four channels that failed. Barley - Out of the 100 channels available to record essentially the same information as above, there were no channel failures. AIRCRAFT PCSITION IN SPACE Weiter - At time zero, the aircraft was flying at an altitude of 19,920 feet on an inbound heading of 070.8°, 52 feet offset, The horizontel range was 3,729 feet and The shock arrival position was 20,129 feet altitude, 19,532 feet horizontal range and 2,566 feet offset to the right. Barley - At time zero, the aircraft was flying at an altitude of 23,318 feet on an inbound heading of 060.4°, The horizontal range and offset were 16,653 feet and 22,237 feet respectively. At shock arrival, the aircreft wes at 23,075 feet altitude, 22,443 feet offset, and 3,757 feet horizontal range. - 39 - al Qp seme
