Variation of Sound Directivity From a Supersonic Nacelle

Mitchell L. Sugar, Paul E. Slaboch
Proc. ASME. IMECE2022, Volume 1: Acoustics, Vibration, and Phononics, V001T01A002, October 30–November 3, 2022
Publisher: American Society of Mechanical Engineers
Paper No: IMECE2022-96515
https://doi.org/10.1115/IMECE2022-96515
... Abstract The effects of aircraft flight speed and fan face pressure variations on sound propagation from an axisymmetric commercial supersonic engine inlet were studied using numerical methods. A computational fluid dynamics (CFD) model of the inlet was constructed in Ansys Fluent. The results...
