Abstract: An apparatus and method for flight control of an aircraft provides a body with adjustable intake ports ducting air into an internal intake manifold. Adjusting the openings of the intake ports changes the amount of air flowing over the surfaces surrounding the intakes, changing the amount of lift created by those surfaces. The intake manifold feeds air to at least one engine, and an exhaust manifold communicates the exhaust of the engine to exhaust exit ports. The exhaust manifold contains a plurality of moveable components that direct exhaust within the exhaust manifold and to particular exhaust exit ports for producing various levels of force imbalance among the exit ports. A compressor powered by the engine provides air to bleed-air ports on the wings. Varying lift on the forward surfaces with the intake ports, vectored exhaust, and bleed air are used to control and stabilize the aircraft during flight, obviating the need for aerodynamic control surfaces.

Directly below the perimeter of the air duct exhaust are mounted a plurality of trough shaped air deflection assemblies (32) each including a rotatably adjustable half trough (44) for selectively scooping a portion of the drive air, and a stationary adjacent half trough (36) for receiving the scooped drive air and redirecting it outward and upward from the air duct.

Abstract: A high-speed vertical take-off and land (HSVTOL) aircraft includes a disk-shaped fuselage wit a rotatable fan having a nozzle ring driven by hot jet gasses and fan air from jet engines. Feed ducts and an annular plenum, have a composite duct-in-duct configuration to separate the hot gases from the relatively cool fan air. High efficiency air bearings serve to support the rotatable fan assembly on the fuselage in the vertical direction, and rollers around the perimeter provide horizontal support and stability. A bearing and seal interface hub and other components, are isolated from the hot gases. The combined exhaust is ejected downwardly at approximately 15° for maximum fan spin and provide direct reaction lift. The fan blades are angled at approximately 57° with moveable airfoil portions and stationary trailing flap portions to provide maximum lift and down wash. Various diverter valves and bypass doors are provided for hot gas/air control.

Abstract: A mechanism and methods for directing the flow of exhaust gases associated with a V/STOL aircraft. A pair of constant area nozzles are associated with a plenum chamber that receives and contains exhaust gases. The nozzles are independently rotatable within circular exhaust openings in the plenum chamber to direct, or vector, exhaust exiting from the plenum chamber in preselected directions such as vertically downward or directions forward or aft of the vertical plane.

Abstract: In at least one embodiment, the apparatus of the invention is a flight vehicle tail assembly having an exterior surface, at least one first vent in the exterior surface, at least one second vent in the exterior surface, and an air passage connecting the at least one first vent to the at least one second vent allowing air to flow therebetween. Where the at least one first vent is located near a high air pressure area acting on the exterior surface during a range of predefined flight conditions. Further, the at least one second vent is located near a low air pressure area acting on the exterior surface during the predefined flight conditions. So that at the predefined flight conditions adverse loads on the tail assembly are reduced by venting air from the high pressure area, through the tail assembly, to the low pressure area.

Abstract: A thrust directing mechanism to vector thrust and control discharge throat area with a number of vanes mounted across the passage. The mechanism includes a control link pivotally coupled to each of the vanes. The control link is selectively movable to correspondingly pivot the vanes and has at least two degrees of freedom corresponding to a two coordinate position. A desired orientation of the vanes may be determined as a function of the two coordinate position. The discharge exit area is contracted by adjusting convergence of the vanes. During convergence, the vanes are pivoted to various pivot angles selected to optimize thrust efficiency when contracting the throat area.

Abstract: A cascade thrust reverser for use with a mixer/ejector noise suppressor has a set of internal blocker doors controllably moveable between a stowed position, where engine exhaust passes through and out the tailpipe, and a deployed position, where engine exhaust is blocked and redirected out a pair of cascades or louvers. External cascade doors cover the cascades from the outside during flight, but are moved aft, exposing the cascades, when the blocker doors are deployed subsequent landing. In a preferred embodiment, the cascade doors and the blocker doors are interconnected through a pair of actuation mechanisms, whereby movement of the cascade doors is sequenced to the motion of the blocker doors. The blocker doors and the cascade doors are shaped to provide a clean aerodynamic profile when stowed, so that the noise suppressor functions optimally. The actuation mechanisms also preferably include lock mechanisms for only allowing the thrust reversers to be deployed just subsequent landing.

Abstract: A lock for a thrust reverser comprising a retainer member carried by a pivot pin, the pivot pin being angularly moveable between a first position in which the retainer member retains a part of the thrust reverser and a second position in which the said part of the thrust reverser is not retained by the retainer member. The lock further comprises a lock arrangement for retaining the pivot pin in its first position, the lock arrangement comprising a lock member axially moveable between a locked position, in which it cooperates with the pivot pin to prevent movement of the pivot pin from its first position to its second position, and a retracted position, an arrangement for restricting angular movement of the lock member, and a solenoid actuator arranged to control movement of the lock member.

Abstract: An exhaust nozzle includes cascade vanes mounted in a duct for discharging exhaust. The vanes have a dolphin profile which is effective for turning subsonically the exhaust near leading edges of the vanes, and then diffusing supersonically the exhaust downstream therefrom. Thrust efficiency of the vanes is therefore shifted to lower pressure ratios during operation for improving performance of the nozzle.
