Abstract
A KNOWLEDGE OF THE VELOCITY DEPENDENT GAS SURFACE ACCOMMODATION BEHAVIOR OF AMBIENT SPECIES IMPACTING HIGH PERFORMANCE AEROSPACE MATERIALS IS CRITICAL FOR THE PROPER DESIGN OF HYPERSONIC VEHICLES WHICH OPERATE IN RAREFIED ATMOSPHERES. WE PROPOSE TO EMPLOY A UNIQUE BEAM SOURCE WHICH CAN PROVIDE HIGH FLUXES OF OXYGEN ATOMS AND MIXTURES OF N/N2 AT HYPERSONIC VELOCITIES OF INTEREST, 4 TO 12 KM/S TO INVESTIGATE SURFACE ENERGY AND MOMENTUM ACCOMMODATION OF THESE HIGH VELOCITY GASES ON SELECTED MATERIALS. THE RESULTING DATA BASE WOULD FIND DIRECT APPLICATION FOR PERFORMANCE PREDICTIONS FOR FLIGHT VEHICLES SUCH AS AFE AND NASP.
