Levin QBIECTIVE The objective of Project $.6 is to determine the reaponses of an ineflight F-lOlA aircraft to the thermal, blast and gust effects of a nuclear detonation. The aircraft was instrumented with radiometers, calorimeters and Preamina tranducera tn mananee she theme) ani? blact nae strain gages, thermocouples ani various other instruvents to measure the aircraft responses to the inputs, For thie shot, the aircraft wae positione? to theoretically receive 308 design limit distrituted up load on the stabdlator based on the positioning yieli, AIRCRAST POSITION IV SPACE The alreraft was to fly a: 12,7O feet absslute on an inbound heading cf A60°T at a TAS of 8X fps. It was planned that che af-craft would be 7,Y° feet short of ground rero at T, with shock arrival occurring 8.75 secovis later with the aircraft over ground zero. Actual shot day position showed the aircraft to be 7,540 feet short of ground Bero at T, with shook arriving 3.833 eeconds later with the aircraft being 30 fet short of ground zero.
