ABSTRACT:
An airplane having a number of airfoils including a delta nose wing, a winglet, a midspan wing, a V-tail delta wing without an upswept fuselage, a vertical tail and upper body stabilizer. These airfoils are coupled with a system of four jet engines and an aft center of gravity. Full control of the airplane is possible under high maneuverability conditions, extremely high accelerations and at large angles of attack. The delta nose wing creates swirling vortices that contribute substantially to the lift of the nose section. The winglet, an extension of the delta nose wing, allows the turbulent wake from the leading edge of the delta nose wing to flow over its upper surface to create additional lift while the midspan wing causes the turbulent flow over its upper surface to form a turbulent wake at its leading edge. The V-tail delta wing with a V-shaped underside and blunt leading edge gives additional lift and control to the airplane. A flow regulator helps to direct and control the flow field to the underside of the delta nose wing and nose strake. There are eight pairs of control surfaces including an upper body stabilizer system for the control and stability of the airplane. The design and locations of the airfoils and jet engines provide rising hot air (exhaust) over the top, inner portion of the midspan and tail wings, a low pressure region over the top of the airfoils, and a higher pressure region on the airplane underside to create the necessary lifting forces. The center of gravity is located aft of the airplane between the exit nozzle of the forward engines and forward of the transverse centerline of the aft landing gears.
