URANS Analysis of a Launch Vehicle Aero-Acoustic Environment

Predicting and mitigating acoustic levels become critical because of the harsh environment during space vehicle lift-off. This paper aimed to study aero-acoustic a rocket The sound propagation within launch event was studied using dedicated computational fluid dynamics (CFD). resolution all phenomena that occur is unfeasible. We discuss turbulence simplification propose feasible simulation through an unsteady Reynolds-averaged Navier–Stokes (URANS) model. results were validated with experimental data showing good correlation near fairing surface improvable accuracy in far field. To assess noise generation, main shock waves identified, evolution generated pressure assessed. Moreover, vertical directivity revealed by analysis field surrounding fairing.
