Active Flow Control for High-Speed Weapon Release from a Bay

Abstract

In recent years work at the Air Force Research Laboratory Air Vehicles Directorate has focused on pursuing active flow control (AFC) devices for achieving better weapons bay control with regard to acoustic loads reduction and weapon separation characteristics than the control offered by passive devices (spoilers). This paper describes the Long Range Strike Aero Experiment which was a systematic study that pursued AFC actuators integrated in a 10%-scale weapons bay model representative of a Long Range Strike Aircraft configuration. Results are presented from acoustic testing, grid testing with force-balance and pressure instrumented weapon models, and drop testing. Based on these measurements, conclusions are drawn with regard to the physical processes that characterize high-speed weapon release from a bay without and with active flow control.
