A controllable-strake concept for alleviating the adverse effects of strake vortex breakdown and asymmetry on the longitudinal and lateral aerodynamics of strake-wing configurations at high angles of attack is presented. The concept aims to control the strake load independently of angle of attack and sideslip by varying the anhedral angle of strakes hinged along the root chord. The strakes may be deflected in a symmetrical or nonsymmetrical mode for a variety of control functions. Results are presented of an exploratory wind-tunnel investigation to evaluate the potential of the hinged-strake concept for enhancing the three-axis controllability in post-stall flight.
