Visualizing Interior And Exterior Jet Aircraft Noise, Manmohan Singh Moondra
Wayne State University Dissertations
In today's competitive aerospace industry, the quest for quiet has drawn significant attention to both the interior and exterior design of an airplane. Understanding the noise generation mechanisms of a jet aircraft is a crucial first step toward developing the most cost-effective noise and vibrations abatement methods. In this investigation, the Helmholtz Equation Least Squares (HELS) based nearfield acoustic holography will be used to understand noise transmission caused by jet engine and turbulence into the fuselage of a jet aircraft cruising at 30,000 ft.
Modern propulsive jet engines produce exterior noise sources with a high amplitude noise field and complicated …
