  • Patent number: 8317126
    Abstract: An aircraft having a lift/propulsion unit which includes a power unit such as a turboshaft engine which drives a fan through a transmission mechanism. The fan discharges to vectoring nozzles which can be independently swivelled to provide lift or propulsion thrust. An output shaft of the transmission mechanism serves as the main shaft of a motor/generator of modular form. The motor/generator can act as a generator to charge an electrical storage device such as a battery, or as a motor to drive the fan, either alone or to supplement the output of engine. Reaction control nozzles are provided at extremities of the aircraft to provide stabilizing thrust. The aircraft is capable of vertical take off and hovering, with the vectoring nozzles swivelled to a lift position, and forward thrust with the vectoring nozzles swivelled to a propulsion position.

  • Patent number: 8251308
    Abstract: Conventional bottom blade type trefoil flight vehicles have composite structures wherein a plurality of pairs of fixing plates, forward/backward adjustment blades, and left and right rotation adjustment blades are separately mounted and adjusted, and thus have difficulties in scouting and surveillance in an indoor area due to the heavy weights and the large volumes of the flight vehicles. Another conventional flight vehicle has drawbacks in that flight in the left and right directions is difficult, and an adjustment blade and a fixing plate are arranged adjacent to each other to cause mutual influences of wind and non-uniformity in the flow of wind. The present invention provides a flight vehicle characterized in that three pairs of fixing plates with fixed pitch propellers and adjustment blades are installed at an angle of 120 degrees.

    Abstract: A module (10) for use with a bypass turbofan engine. The module comprises a hot flow channel through which the hot gas flow generated by the engine can flow and a bypass flow channel (14) through which the bypass air generated by the engine can flow. Part of the bypass air may be re-directed to be exhausted from the module at an angle relative to the longitudinal axis of the module so as to create vertical thrust. The hot flow channel may be separated from the bypass flow channel by a porous separator (12) that allows a degree of mixing between the hot gas flowing in the hot gas flow channel and the cold gas flowing in the cold gas flow channel.

    Abstract: An aircraft with this VTOL technology (the Invention) (6,7,8,9,10,18,19,20) can achieve VTOL even its thrust-to-weight ratio is smaller than 1. It is impossible for an aircraft with a thrust-to-weight ratio smaller than 1 to take off and land vertically with traditional technologies. The present invention, however, can achieve VTOL on these aircraft (6,7,8,9,10,18,19,20) by generating another lift force for VTOL by horizontally setting a Thin Wing (2) at the middle of the perpendicular line of the horizontal section inside the Air Intake Duct (5,6) in addition to the lift force obtained by traditional ways. This invention can be used to retrofit an existing aircraft to achieve VTOL or manufacture a VTOL aircraft with a thrust-to-weight ratio smaller than 1.

  • Patent number: 7823838
    Abstract: An aircraft has a wing 10 supporting at its underside a gas turbine engine 13. A jet pipe 14 of the engine has an exhaust nozzle 15 of rectangular flow area defined by upper and lower panels 16,17 and end walls 18. The upper panel, which is a part common to the nozzle and to a trailing edge portion of the wing, comprises a pair of flaps 20,21 which are pivotal between a position of alignment with the wing 10 and a position in which they are inclined to the wing. A part of the gas flowing through the jet pipe is diverted through a passage 25 into a passage 26 defined between the flaps 20,21 so as to entrain and accelerate air 26A flowing over the wing 10. This increases the lift of the wing at the rear thereof and also increases the thrust developed at the nozzle 15.

    Abstract: An aircraft having a gas turbine engine with vectorable cold and hot nozzles. The aircraft is provided with a ducting in the wing which extends from an inlet facing downwards to an outlet in the upper surface of the wing directed rearwardly. The cold vectorable nozzles of the engine are designed so that they can be swung from a vertical downward position to provide vertical lift to a horizontal position directed rearwardly to produce forward thrust, to a position where they are directed upwardly and discharged into the ducting 24. In this way, the air discharged through the outlet of the ducting 24 enhances the aerodynamic lift produced by the wing at slower speeds by inducing the air flow over the wing. In addition, the forward component of the thrust produced in the ducting provides a forward thrust on the aircraft, whilst additional forward thrust is produced by swiveling the hot nozzles.

    Abstract: A balanced thrust vectoring system for an aircraft designed to provide even weight distribution, simple thrust vectoring, and hover stability. The system includes a main diverter that connects to a jet output port. Located inside the diverter is a 4 way splitter that divides the diverter into four equal volumes. Attached to the diverter and adjacent to the two upper volumes are two front upward extending ducts. Attached to the diverter and adjacent to the two lower volumes are two rear upward extending ducts. Each duct includes an upper bend that and diagonally aligned nozzle opening. Each duct has only two bends which help vector the exhaust downward in an efficient manner. The diameter of each duct is consistent to allow their entire length to maximize air flow.

    Abstract: A module (10) for use with a bypass turbofan engine. The module comprises a hot flow channel through which the hot gas flow generated by the engine can flow and a bypass flow channel (14) through which the bypass air generated by the engine can flow. Part of the bypass air may be re-directed to be exhausted from the module at an angle relative to the longitudinal axis of the module so as to create vertical thrust. The hot flow channel may be separated from the bypass flow channel by a porous separator (12) that allows a degree of mixing between the hot gas flowing in the hot gas flow channel and the cold gas flowing in the cold gas flow channel.

  • Patent number: 7281680
    Abstract: The aircraft incorporates a single ducted propeller. The fuselage Bridges over the ducted propeller assembly, and is shaped in a way that the incoming air can smoothly flow into the propeller area. The duct has an aerodynamically shaped frontal area, and an aft extension, which forms the tail section. The wings are attached to the side of the duct. The ducted propeller assembly also contains louvers, which run span wise, to redirect the outgoing air in horizontal direction. During vertical take-off or landing, the propeller has a horizontal plane of rotation, after take-off the whole craft entirely tilts forward approximately 26 degrees to transition into horizontal wing born flight. During vertical flight, the aircraft is controlled by control louvers installed inside the ducted propeller assembly in the propeller slipstream.

  • Patent number: 6926229
    Abstract: Aircraft having thrust vectoring for switchably providing upper surface blowing. The aircraft generally includes a wing and an engine. The engine can be rotatably supported to supporting structure to allow the engine to be controllably rotated relative to the wing, and/or the engine can include a thrust vectoring nozzle. The engine's thrust vectoring capabilities allow the exhaust flow to be controllably vectored to switch on or off upper surface blowing depending on the aircraft's phase of operation. During a first phase, the exhaust flow can be vectored to flow across the upper wing surface to provide upper surface blowing to augment lift. During a second phase, the exhaust flow can be discharged generally downstream or rearwardly. The engine is positioned relative to the wing such that the exhaust flow does not provide upper surface blowing during the second phase.
