Abstract : An experimental program was conducted to assess the feasibility of simulating the peak thermal environment encountered by a hardened structure exposed to a nuclear blast. An earlier study (DASA 253) indicated the potential capability for explosive shock tubes to simulate nuclear fireball environments from 10,000 K to 100,000 K. Tasks in the present study included experimental verification of the structural and gasdynamic aspects of the simulator operation and verification of the thermal environment produced using high temperature radiometry. An additional task included in the program was an attempt to calculate fireball ablation using a sophisticated boundary-layer code. (Author)
