Vortical Flow Management for Improved Configuration Aerodynamics - Recent Experiences
Abstract
This paper reports recent progress in vortex-control applications for alleviating the adverse consequences of three-dimensional separation and vortical interactions on slender body/swept wing configurations. Examples include: helical separation trip to alleviate the side force due to forebody vortex asymmetry; hinged strakes to avoid vortex breakdown effects; compartmentation of swept leading-edge separation to delay the pitch-up instability; under-wing vortex trip and vortex flaps for drag reduction at high lift; and an apex-flap trimmer to fully utilize the lift capability of trailing- edge flaps for take off and landing of delta wings. Experimental results on generic wind-tunnel models are presented to illustrate the vortex-management concepts involved and to indicate their potential for enhancing the subsonic aerodynamics of supersonic-cruise type vehicles.
