wal : @ 200 4h ‘ = TCA) Project 5.6 - In-Flight Participation of an F-1ClA Aircraft = Capt KH. Levin OBJECTIVE The objective of Project 5.6 is to determine the responses of an in~flight F-101A eireraft to the theraal blast and gust effects of a nuclear detonation. A correlation of the responses, combined with known character- istics of any veapon, will be used to define the maximum safe delivery capability of the aircraft. ROM Tre aircraft was instrupented with rediometers, caloriasters and pressure transducers to seasure the therma) and blast inpute ead with streis gages, tPermocouples and various othexy at responses to the inputs. Fa » instruments to seasure the eircreft (Inca), the aircraft was positioned to receive maximm gust inputs consistent vith ainim nuclear radiation. By positioning to theoretically reosive 3.6 M, the maximum expected gust Tespense was about 75%. POSITION The aircraft was to fly at 9,000 feet absolute altitude on an inbound heading of 040° at « ground speed of 920 feet per second. It was plaaned that the aircraft would be 5800 feet short of ground sero at sero time with shook arrival occuring 0,3 seconds later directly over ground sero. Actual shot position was on time and 120 feet to the right of the planned ground sero position with the ehock erriving o.4 seconds later 550 feet beyond ground sero and 200 feet to the right of the desired position at time of shook arrival BEST AVAILATLE Copy HG
