Effects of a Generic Store on Cavity Resonance at Supersonic Speeds

What is it about?

Supersonic flow over a cavity such as the open internal bay of a tactical aircraft involves a variety of fluid dynamics mechanisms and different types of instabilities, including those associated with the shear layer, flow-induced resonance, and turbulence. The current study presents experimental data on the response of cavity dynamics to the introduction of various store configurations mounted at different locations within the cavity. Results show that the presence of a store and its location with respect to the cavity shear layer plays an important role in the cavity acoustics.
