Abstract : This report details an experimental program developed to demonstrate that the combined effect of nuclear thermal/blast loading is significantly greater than either of these types of loading acting alone. The report covers the experiments and the preliminary computer simulation used in the design of the experiments. The experimental program was designed to study the effects of thermal/blast loading on a generic aircraft structure. The structure used was a hollow, circular cylinder with clamped ends representing a bay in a missile body. The experiments were conducted in the BRL Thermal/Blast Simulator. The nuclear loading simulation produced in this facility consists of a thermal radiation pulse from a controlled aluminum/oxygen burn followed by a shock wave from the shock tube. During the program instrumented target cylinders were exposed to three types of loading: blast loading, thermal loading and combined thermal/blast loading. By comparing the results of the three types of experiments it was demonstrated that the structural response to the combined loading was different in both magnitude and character from the response to either blast or thermal loading.
