An STOL aircraft structure has a variable-attitude, variable-area wing in addition to a traditional airfoil. The variable wing has an angle of attack that varies from 0° to a predetermined angle far in excess of the stall angle. The variable wing area can be adjusted from 0% to 100% by a roller furling arrangement. The aircraft structure operates during takeoff by deploying the variable wing with an attitude exceeding the stall angle, applying thrust to the aircraft so that the variable wing generates reaction lift and the aircraft attains a predetermine...
1. An aircraft structure adapted for short takeoff and landing performance comprising:a fuselage with a longitudinal axis; a wing extending transversely of the fuselage and attached thereto, having a normal flight position and an area, the fuselage and the wing in the normal flight position having a stall angle; thrust means attached to one of the fuselage and the wing, operable to move the fuselage generally in the direction of the longitudinal axis; a deployable wing with a wing axis, operably connected to the fuselage so that an angle of attack define...
