Project 5.8 = In-Flight Participation of an A3D-] Aircraft ~
LCdr. P, S. Harward
Objective
The objective of this test was to investigate the A3D-1 aircraft
capability for the delivery of high yield nuclear weapons by the measurement and 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 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
The A3D-1 aircraft was flying at an absolute altitude of 14,050 feet,
heading 124°T in a tail-on position at H # 0,
Slant range to Ground Zero
at H # O was 18,425 feet, (Aircraft TAS 768 ft/sec) aircraft position at
time of shock arrival (H ¢ 27.2 sec.) was 35,300 feet slant range on a
heading of 124°T at 14,050 feet absolute altitude,
