A variable area nozzle assembly for a gas turbine engine includes a fixed structure surrounding an exhaust duct extending along a nozzle centerline. The fixed structure further includes a first lateral side and a second lateral side opposite the first lateral side. The variable area nozzle assembly further includes a nozzle. The nozzle includes a nozzle outlet including a nozzle outlet cross-sectional area. The variable area nozzle assembly further includes a thrust reverser system including a first thrust reverser door and a second thrust reverser door. The first thrust reverser door is pivotably mounted to the fixed structure at the first lateral side. The second thrust reverser door is pivotably mounted to the fixed structure at the second lateral side. The first thrust reverser door and the second thrust reverser door define a portion of the nozzle outlet of the nozzle.

A vertical take-off and landing aircraft is provided. The aircraft comprises a fuselage which has a nose end, a tail end, and a plurality of seats disposed in the interior. A pair of rear wings extend outwardly from opposing sides of the fuselage between a cockpit and the tail end, and a pair of front wings extend outwardly from opposing sides of the fuselage between the cockpit and the nose end. Each of the pair of rear wings and front wings includes an adjustably mounted turbine which comprises a statically mounted fan pod, a duct rotatably connected to the fan pod, and an adjustable nozzle rotatably connected to the duct. The nozzle can be adjusted to a variety of configurations ranging between a vertical position and a horizontal position via the duct. The adjustably mounted turbine enables the aircraft to adjust thrust through vectors ranging between horizontal and vertical.

A system and method for vectoring the thrust of a supersonic, air-breathing engine. A thrust vectoring mechanism uses two asymmetrically staggered ramps; one placed at the throat, the other positioned at the exit lip of the nozzle of the engine to re-direct exhaust flow off-axis with the nozzle.

A thrust unit for a propulsion device includes a thrust engine, arranged to provide a thrust force oriented in a direction so as to provide substantially vertical take-off and landing capability, and a deflector assembly comprising a pair of deflecting elements arranged to selectively divert the ejected fluid and movably mounted in the fluid outlet path. In order to reduce the bulk of the thrust unit and improve reliability and responsiveness, the invention relates more particularly to the positioning of the deflecting elements opposite the ejected fluid.

A fuselage for an aircraft. The fuselage has a control element with an integrated engine outlet. The control element is integrated at a rear end of the fuselage, so that the control element terminates flush with an outer skin of the fuselage in a circumferential direction of the fuselage. An outer wall of the control element surrounds the engine outlet wherein the engine outlet is directed towards an open rear side of the control element. The control element is connected to the fuselage such that the control element jointly the engine outlet is pivotable about a rotation axis with respect to the fuselage. The rotation axis runs transversely to a longitudinal direction of the fuselage and the control element functions as a tailplane when pivoting about the rotation axis.

A thrust reverser for an aircraft propulsion assembly, this reverser including an outer structure movable between a closed position and an open position of two primary latches configured to lock the movable outer structure in the closed position. The movable outer structure includes an output end that is oblique with respect to the longitudinal central axis so as to orient the thrust laterally. In order to compensate the tilting moment of the movable outer structure, which results from this lateral orientation of the thrust, the primary latches are offset with respect to a median longitudinal plane passing through the longitudinal central axis of the reverser.

A ducted-fan unmanned aerial vehicle (UAV) capable of low-energy high-rate maneuvers for both vertical roll control and horizontal pitch control. The UAV includes ducted fans which are with respective piezoelectric-actuated thrust vectoring flaps. Thrust vector control is achieved by controlling the angular positions of a plurality of thrust vector flaps pivotably coupled at respective outlets of a plurality of ducts having fan rotors at the inlets. Each thrust vectoring flap has only one degree of freedom in the frame of reference of the UAV, namely, rotation about a single axis that is perpendicular to the axis of the duct. The angular position of the flap is controlled by sending electrical signals to a piezoelectric actuator (e.g., a piezoelectric bimorph actuator) having a voltage sufficient to cause the piezoelectric actuator to bend.

A flow vectoring turbofan engine employs a fixed geometry fan sleeve and core cowl forming a nozzle incorporating an asymmetric convergent/divergent (con-di) and/or curvature section which varies angularly from a midplane for reduced pressure in a first operating condition to induce flow turning and axially symmetric equal pressure in a second operating condition for substantially axial flow.
