Jet Noise Suppression Systems For High-Speed Aircraft 730897

Jet noise is a major problem for high-speed aircraft. Efficient methods of reduction must be found to have an economically viable and ecologically acceptable airplane. This paper discusses reduction techniques and constraints. Specific suppression systems are presented as an evaluation of current work. An analysis of the effect of suppressors on airplane performance is presented to demonstrate the requirement for step improvements over suppression systems considered previously.
