This activity aims at studying the feasibility of predicting acoustic loads on the structure of a space vehicle originating from the supersonic exhaust plume of a thruster rocket engine, including prediction of the aero-elastic response of the structure. The following objectives are foreseen: (1) Develop and assess the modelling capability to predict the jet acoustic loads on launch vehicles by computing the generation of sound by the supersonic jet of a launcher engine and the propagation of sound to the launcher body. (2) Develop and assess the modelling capability to predict the influence of the jet acoustic loads on the dynamic aeroelastic analysis of structural components. Procurement Policy: C(3) = Activity restricted to SMEs & R&D Entities.
