Abstract:

This report summarizes the performance technology developed during the DOT phase II task III program. Thrust performance design guidelines are established within mechanical constraints and acoustic criteria for low noise multitube-suppressor exhaust systems. Model-scale tests were conducted that investigated detailed performance interactions and overall performance for multitube suppressorejector exhaust systems. The effects of geometry, jet pressure and temperature, and external velocity on performance are analyzed. A concurrent program for the development of acoustic technology is reported upon in volume II.
