Summary
A launch vehicle company, developing a range of small launchers, is looking for an acoustic attenuation system for its fairing to reduce the acoustic environnement seen by the satellite during its launch phase.
Description
During the flight, the spacecraft is exposed to a variety of mechanical, thermal, and electromagnetic environments. In particular, the acoustic pressure fluctuations under the fairing are generated by engine operation and by unsteady aerodynamic phenomena during atmospheric flight, which are transmitted through the upper structure of the launch vehicle. The satellite, in general, can only withstand a reduced environment in terms of acoustics. Most often, to reduce this environment, the two half-fairings of the launcher use acoustic attenuators
