Abstract:

Technical issues regarding the aerodynamics and optics of aircraft turrets are of critical importance to the Air Force Weapons Laboratory. Of specific interest are the optical properties of the separated flow over aircraft turrets. Turbulence generated by flow separation imparts significant distortion on laser beams. Control of flow separation from the turret and the resultant development of the turret wake will result in improved energy propagation at aft targets. The paper describes a survey of high-lift airfoil flow-control technology and its application to separation control on aircraft turrets. A flow-control concept screening methodology is developed and applied to conceptual designs. The effectiveness of wind and water tunnel testing for screening flow-control concepts has been evaluated. Flow parameters have been bracketed and the simulation quality of the mechanisms of flow control established for each facility. Water channels are recommended for screening tests for many of the conceptual designs.
