The effectiveness of extended plug nozzles in reducing jet engine exhaust noise was investigated on small scale laboratory nozzles at ITT Research Institute and on a small turbojet engine at Williams Research Corp.
The geometry of the nozzle was optimized on the basis of noise reduction versus thrust loss. The extended plug reduced noise on both laboratory nozzles and the turbojet engine for pressure ratios above critical.
The use of a small turbojet engine for evaluating noise suppression devices is described.
