A retractable chine assembly includes at least one chine which is hingebly mountable to a surface such as of an aircraft having a wing. The chine is preferably configured to be movable between stowed and deployed positions. The aircraft may include an engine nacelle which may be mounted on an underside of the wing. The nacelle may generate a nacelle wake that passes over the wing upper surface at high angles of attack and induces flow separation. The chine is preferably configured such that a vortex generated thereby interacts which the nacelle wake to d...


1. A retractable chine assembly for an aircraft including an engine nacelle and a wing having a wing upper surface, the chine assembly comprising: at least one chine hingedly mounted on an inboard side of the engine nacelle;wherein:the chine is configured to be movable between stowed and deployed positions;the chine generating a vortex passing over the wing upper surface and interacting with a wake generated by the nacelle in a manner increasing wing lift. 2. The retractable chine assembly of claim 1 wherein: the chine is disposable against the engine na...
