Theoretical and experimental research was conducted to investigate the geometrical and fluid mechanical parameters important in the acceleration of solid particles to hypersonic velocities. A combination-heated erosion-ablation facility providing flows with reservoir enthalpies up to 2000 Btulb was assembled and techniques for injecting well-controlled amounts of silicon dioxide particles into the nozzle flow were developed. A laser doppler velocimeter was at the nozzle exit. A digital signal processor capable of measuring particle velocities up to 8000 ftsec was designed and assembled. Performance characteristics of the various system components are discussed. Author
