This report contains the results of an investigation as to the feasibility of simulating nuclear gust loading on a B-52 fin or wing by a mechanical dynamic test. The investigation was accomplished by use of a mathematical simulation of mechanical test setup. The results show that a test simulating nuclear gust loads is feasible and the resulting bending moments in the critical areas of the fin a wing compare well with bending moments calculated using the VIBRA-4 computer code. Two possible test setups for a B-52 fin test are described. In one method, the loading is input by fast acting pneumatic actuators attached to the fin main spar. In the other method, the loading is induced by rapid acceleration of the fin support structure. The report also contains a discussion of basic consideration for an aircraft mission completion investigation. Author
