Project 5.6 = In-Flight Participation ef an F-l01A —- Capt. M. B. Lewin The objective of Project 5.6 is to determine the responses of an ineflight P-l01A airqraft to the thermal blast and gust effects of « nuclear detonstion, A correlation of the responses, combined with known character- istios of any weapon, will be used to define the maximm safe delivery capability of the aircraft, IESTRRGETATION : The airereft was instrumentad vith radiometers, eslorineters ani pressure transévcers to measure the ‘hermal and blast inputs and with streia gages, thermocouples and various other instruments to measure the aircraft response to the inputs, For this shot, the alroreft was positione! to theoretically receive a AT of 350°F on the 0,020" skin covered honeyooud warfaces based on the positiening yield and the on-time position. afreraft was to be flewn at supersonic speed. The It was expected that it weuld out run the shook, thus gathering no gust date, AXRCRAPTIs The aircreft was to fly at 21,500 feet absolute altitude on an inbound heading of 040° at a ground epeed of 1170 fps. It was planned that the air- ereft would be beyond groun! sero at a distance of 8500 feet at time sero, Aotual shot position was 470 feet short and 260 feet to the right of the Planned position, The aircraft out ran the shock, “itDanese BEST AVAILABLE COPY Bavdeme Semple: The black rain erosion coating wes scorched corEeD'ock a cps OA 4 EZ
