Identification of noise sources during launch using phased array microphone systems
Los Angeles CA (SPX) Apr 26, 2024
Every part of a launch vehicle, launch pad, and ground operation equipment is subjected to the high acoustic load generated during lift-off. 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 reductions of the acoustic levels can tra
