Corebreaker and Blockage Evaluation Test in the AEDC Aerothermal Mach Number 4 Wind Tunnel.

Abstract

Tests were performed in the AEDC Mach number 4 wind tunnel to determine corebreaker effectiveness for reducing pressure fluctuations in the stilling chamber. Basic blockage data were also obtained using blunt and conical models to determine maximum model size for the facility. Another test objective was to confirm that the upper operating temperature limit of 1900 R could be achieved. The stilling chamber pressure ranged from 15 to 100 psia, with temperatures from ambient to 1900 R. (Author)
