Noise Mitigation of a Supersonic Jet Using Shear Layer Swirl
Abstract
Explore a promising technology of using swirl inducing vanes to achieve significant engine noise reduction levels (3+ dB) for legacy engines. Test influence of vane location, swirl angle, and blockage effect on jet flow-field and acoustic signature. Validate and verify computational and experimental testing procedures to ensure high confidence in results. Establish thrust differentials for the vaned nozzle configurations. The ultimate objective is to achieve substantial noise reduction at full-scale, at full power
