Connecting analyses of installed tactical jet engine noise with simulated and laboratory-scale data
Abstract
Because of warfighter health and environmental impacts, reducing noise from high-performance, tactical jet aircraft continues to be a priority for the Office of Naval Research. Implementing noise reduction technologies at full-scale requires improved knowledge of installed tactical jet noise characteristics and more quantitative connections to laboratory-scale and computational modeling frameworks, where technologies are most efficiently developed and prototyped. The proposed investigations principal goal is to meet these needs. The improvement will be accomplished by analyzing in detail the T-7As F404-103 engine noise source and radiation characteristics, using them to validate matched laboratory-scale measurements and high-fidelity large-eddy simulation (LES) numerical modeling, and then studying the lab-scale and LES data for further insights. The proposed research will elucidate noise generation mechanisms and enable more efficient and complete investigation of noise reduction technologies for full-scale engines. The proposed research will also facilitate in-depth collaboration within the ONR jet noise research portfolio and validate ONR-funded capabilities and facilities.
