摘要:

Jet aircraft and engine test facilities are being designed to operate using air cooling only in the exhaust system. Many of these facilities are experiencing low‐frequency noise due to aerodynamic instability. The presentation will include a discussion of low‐frequency noise generation in jet engine test facilities and measured data. Data are measured down to 2 Hz since much of the noise energy is in the infrasonic frequency range.
