The responses of a B-36 aircraft to the effects of a nuclear detonation at levels approaching the thermal and blast limitations of the aircraft were determined. A B-36D aircraft was instrumented and flown in the vicinity of each of the six shots of the CASTLE sequence. Time-history input and response measurements constituted the main instrumentation mentation effort. For the first five shots, the aircraft was positioned at predicted near-limiting inputs in a simulated delivery configuration, that is, flying away from the explosion. On Shot 6, the aircraft was headed toward the explosion to obtain initial experimental data for this orientation. In addition to the measured data, together with photographs and descriptions of the damage, this report contains pertinent observations as reported by the flight crew. Sufficient are obtained to fulfill the specific objective of the project. A comparison between the experimental data and theoretically-predicted responses is made.
