An airfoil for an aircraft system is provided with a pair of airfoil-like primary fluid flow injectors that are rotatable relative to airfoil structure and to positions that develop aerodynamic lift in conventional flight and fluid-reaction lift in vertical/hovering/transitional flight. An actuator connected to the aft airfoil-like injector functions to selectively rotate such injector to positions whereat the injector trailing edge comprises a part of the airfoil cross-sectional profile associated with aircraft system attitude-stabilized flight, is positioned above such profile to reduce airfoil camber and associated aerodynamic lift, or is projected below such profile to define, in combination with the other airfoil-like injector, a lift ejector diffuser section. |
