Abstract:
The jet noise and specific sound field produced by a rocket engine on the ground test stand were measured, and the vibro-acoustic model was built based on statistical energy analysis to predict the noise environment of the rocket engine. During the test, the sound pressure levels around the engine nozzle and the payload cabin were measured. The result can support the noise spectrum prediction of the key rocket part.
