(2022) Exploring angle-of-attack effects in the aero-acoustic response of a weapons bay at transonic and supersonic Mach number. In: 28th AIAA/CEAS Aeroacoustics 2022 Conference, 14-17 June 2022, Southampton, UK. AIAA 2022-3008https://doi.org/10.2514/6.2022-3008https://dspace.lib.cranfield.ac.uk/handle/1826/18160Numerical aero-acoustic analysis was conducted on a weapon bay model with doors, incorporating radar cross section reduction features. The effect of angle of attack on the aero-acoustic response of the cavity was analysed at a transonic Mach number of 0.85, and at a supersonic Mach number of 1.20. It was found that incidence had influence on both mean-flow features and acoustic response. Further, linear and angular accelerations induced by the flow on doors revealed potential adverse fluid-structure coupling when results were compared with modal analysis. Again, angle of attack did influence the aeroacoustic effects on the cavity door structure.enAttribution-NonCommercial 4.0 Internationalhttp://creativecommons.org/licenses/by-nc/4.0/Critical Angle of AttackFreestream Mach NumberModal AnalysisRADAROverall Sound Pressure LevelSupersonic SpeedStrouhal NumbersPressure CoefficientShear LayersFluid Structure InteractionConference paper9781624106644
