rie £2 (HURON) Project 5.8 - In-Flight Participation of the A3D-1 Aircraft - LCDR P.S. Har -—-—# Objective The objective of this test was to investigate the A3D-1 aircraft capa-~ bility for the delivery of high yield nuclear weapons by the measurement ar correlation of the in-flight effects of a nuclear detonation. Instrumentation Instrumentation of the A3D-1 aircraft consisted of 96 oscillograph recording channels, one photo recorder, four GSAP (Gun Sight Aiming Point) cameras, and three dosimeters. The data recorded included temperature rise thermal input, rate of thermal input, overpressure, gust loading, aircraft response, engine response, and gamma radiation, Aircraft Position in Space 7€ : The A3D-1 aircraft was flying at an absolute altitude of 12,050 feet with no offset. zero time. Aircraft was on a heading of 286°T in a tail-on position ¢ Approximate horizontal ranges at Ty to Tg were 16,800feet and 48,000 feet respectively. Time of shock arrival was was approximately 4000 feet beyond planned position.
