mm BBcctwc0 Project 5.6 - In-Flight Participation of an P-lOlA Aircraft - Capt M.H. Lewin SBIECIIYE The objective of Project 5.6 is to determine the responses of an in-flight P-l01a sircraft to the thermal blest and gust effects of a nuclear Getonation, A correlation of the responses, combined with known ebarecteristios of any veapon, will be used to define the maximum safe delivery capability of the aircraft. TESTERS The aircraft was instrumented with redicesters, calorimeters end pressure transducers to measure the thermal and blast inputs and vith strain gages, theraccouples and verious other. {pstruments to measure the aircraft Tesponses to the inputs. PerMI(c1crapo) shot, the airoreft ves positioned to receive aaximm gust inpute consistent with alnimus muclear radiation. By positioning to theoretically receive 3.454 REM, the maximm expected gust respoase vas about %%. POSIT The aircraft was to fly at 7,000 feet absolute on an inbound heeding of 040° at a ground speed of 800 feet per second. It vas planned that the aircraft vould be 1700 feet short of ground sero at sero time with shook arrival ocooursing 5.6 seconds later at a horizontal range of 2600 feet. Actual shot position wes 200 feet beyond and 260 feet to the left of the planned sero time position with shock arriving 6.85 seconds later at a borisontal renge of 4000 feet. BR ST al.
