Abstract : The maximum thermal radiation load to which the cockpit of a fighter-bomber may be safely subjected was determined experimentally. Fighter-bombers delivering nuclear weapons under cloud conditions may encounter these thermal radiation loads. A static F-100C cockpit was the test vehicle and four human subjects dressed in full flying equipment were exposed in it to thermal pulses simulating those of nuclear detonations. An unprotected cockpit and pilot can be safely subjected to a range from 3 to 5 cal/sq. cm. if the yield of the weapon is approximately one megaton. This limit assumes adequate protection for the pilot's eyes. Materials in an unoccupied, unprotected cockpit will smoke profusely and char (but not flame) under a load of approximately 10 cal/sq. cm. Partial cracks will form in the plexiglass canopy under an absorbed load of approximately 11 cal/sq. cm. (Author)
