NERVES MUSAPESE2 TEAMATSeeSomesteEES LS 7 ‘ o = EBrice) Project 5.6 - In-Flight Participation of an F-lOlA Aircraft - Capt M, H, Lewin OBJECTIVE The objective of Project 5.6 is to determine the responses of an in-flight F-lOlA aircraft to the thermal blast and gust effects of a nuclear detonation, A correlation of the responses, combined with known characteristica of any weapon, will be used to define the maximum safe delivery capability of the aircraft. INSTRUMENTATION The aircraft was inatrumented with radiometers, calorimetera and pressure transducers to measure the thermal and blast inputs and with strain gages, thermocouples and various other instruments to measure the aircraft response to the inputs. Fer (Apache) shot, the aircraft was positioned to receive a high caloric input, 101 Cal/on’, ata low angle of incidence, At this position the aircraft would theoretically receive aAT of 350°F on the ,020 inch skin covered honeycomb surfaces based on positioning yield and the on-time position, At this position the aircraft would receive 40% design limit load on the stabilator, AIPCRAFT POSITION JN SPACE The aircraft was to fly at 15,000 feet absolute altitude on an inbound heading of 040° at a ground epeed of 950 fps, It was planned that the aircraft would be 19,100 feet beyond ground zero at time zero with the shock orevto at a horizontal range aupuaiiin S Actual shot position was 900 feet beyond and 50 feet to the rirht of planned position at time zero, with shock arriving a ata . vy horizontal range wu SNL -23-
