Identification of Noise Sources During Launch Using Phased Array Microphone Systems

Identification of Noise Sources During Launch Using Phased Array Microphone Systems Every part of a launch vehicle, launch pad, and ground operation equipment is subjected to the high acoustic load generated during lift-off [1]. Therefore, many extreme measures are taken to try to suppress this acoustic environment by damping with a water deluge system and diverting engine plumes away from the vehicle via flame trenches. Even single decibel re…
