Analysis of IXV Space Hardware Exposed to Acoustic Diffuse Random Field

Reusable launchers are recognized as one of the solutions to lower launch costs. Contrary to more traditional expendable launchers, the reusable launchers are able to launch a payload and return part of the structure on the Earth surface. In 2015, ESA launched the Intermediate eXperimental Vehicle (IXV). This vehicle was developed by Thales Alenia Space …
