Abstract
A dynamic cavity air flow system reduces the highly unsteady flow over exposed aircraft cavities by incorporating a series of microjets proximate the leading edge of a cavity. The microjets, which may articulate, issue a supersonic jet flow toward the rear or trailing edge of the cavity whenever the cavity is exposed during flight. The microjets receive the air for the flow from either a dedicated pressurized gas source aboard the aircraft or from bleed air taken from an engine of the aircraft. Appropriate sensors and controllers are provided for control of the system.
