Direct Lift Control for Unsteady Maneuvering of Carrier-Based Aircraft using Distributed Aero-Effected Active Bleed
Abstract
A novel approach to aerodynamic control for maneuvering and landing of carrier-based,fixed wing aircraft in the ship~s wind field b"y augmenting and ultimately replacing theaircraft~s conventional control surfaces will be developed in a coupledexperimental/numerical research program at Georgia Tech. The aerodynamic loads on thelifting surfaces will be controlled using distributed air bleed" that is driven through theaerodynamic surfaces by the pressure differences in flight (e.g., between and across thepressure and su""ction surfaces of the wing), and is regulated by low-power, surfaceintegratedlouver valves. Control by active bleed enables conside""rably faster response time,does not require powered air source, is easily airframe integrable and scalable, can be usedto maneuver""s and stabilize the aircraft in complex wind gusts, and mitigate stall duringslow approach. Closely-coupled measurements and simula"tions on static and dynamic 3-D wing configurations will elucidate the receptivity of the flow over the lifting surfacesto manipulation by the bleed flow to yield desired variations in the global aerodynamicloads. Specific attention will be placed on testing active bleed in configurations that arerealizable on Navy aircraft. Detailed experimental data will facilitate the development ofhig"h-fidelity, fully-validated numerical modeling that will help pave the way towardsprediction of bleed-controlled aerodynamic forces" and moments for vehicle maneuveringon full scale platforms.
