Abstract:
An aircraft 1, 101 capable of thrust-borne flight can be automatically retrieved, serviced, and launched using equipment suitable for a small vessel. For retrieval, the aircraft hovers over a base apparatus 6 having one or more rails 5, 105 which bound a space into which the aircraft can safely descend. When the aircraft's measured position and velocity are appropriate, the aircraft descends promptly such that a spanwise component 4, 104 on the aircraft engages the rails. The teeth 8, 108 restrain the aircraft in position and orientation, while the rails bring the aircraft to rest. Articulation of the rails is used to park the aircraft in a servicing station 14. Connections for refueling, recharging, and/or functional checks are made in preparation for launch. Launch is effected by removing connections and restraints and articulating the rails to put the aircraft in an appropriate position and orientation. The aircraft uses its own thrust to climb out of the apparatus into free flight.
Abstract:
An aircraft (10) takes off, lands, or hovers with at least one wing-mounted thrust-producing device (12) attached to at least one wing (16) of the aircraft and at least two fuselage-mounted thrust-producing devices (18) attached to a fuselage of the aircraft both providing vertical thrust. The aircraft (10) is flown while the at least one wing-mounted thrust-producing device (12) provides horizontal thrust and with the at least two fuselage-mounted thrust-producing devices (18) not providing any thrust.

Abstract:
An unmanned aerial vehicle (UAV) capable of vertical and horizontal flight modes, a method for assembling a UAV, and a kit of parts for assembling a UAV. The UAV comprises a wing structure comprising elongated equal first and second wings; a support structure comprising first and second sections coupled to a middle position of the wing structure and extending in opposite directions perpendicular to the wing structure; and four propellers, each mounted to a respective one of the first and second wings, and first and second sections, for powering the UAV during both vertical and horizontal flight modes.
Abstract:
An aircraft for use in fixed wing flight mode and rotor flight mode is provided. The aircraft can include a fuselage, wings, and a plurality of engines. The fuselage can comprise a wing attachment region further comprising a rotating support. A rotating section can comprise a rotating support and the wings, with a plurality of engines attached to the rotating section. In a rotor flight mode, the rotating section can rotate around a longitudinal axis of the fuselage providing lift for the aircraft similar to the rotor of a helicopter. In a fixed wing flight mode, the rotating section does not rotate around a longitudinal axis of the fuselage, providing lift for the aircraft similar to a conventional airplane. The same engines that provide torque to power the rotor in rotor flight mode also power the aircraft in fixed wing flight mode.
Abstract:
A ducted fan core for an unmanned aerial vehicle is provided that accommodates a wide variety of payloads. The ducted fan core comprises a frame (190), attached to which are an engine (120), gearbox assembly, fan, and a plurality of control vanes (130). A first surface on the frame comprises a plurality of connects or electrical traces. The plurality of connects are used to removably attach a variety of pods (240) carrying various payloads. Thus, a wide variety of payloads may be delivered using the same unmanned aerial vehicle, simply by removing and attaching different pods to a fixed vehicle core. These pods may be shaped so as to form part of the vehicle exterior, and when the pods are attached to the frame, they enhance the aerodynamics of the vehicle.
Abstract:
A VTOL flying-wing aircraft has a pair of thrust-vectoring propulsion units (2, 3; 4, 5) mounted fore and aft of the aircraft pitch axis (PA) on strakes (6, 7) at opposite extremities of the wing-structure (1), with the fore unit (2; 4) below, and the aft unit (3; 5) above, the wing-structure (1). The propulsion units (2-5) are pivoted to the strakes (6, 7), either directly or via arms (56), for individual angular displacement for thrust-vectored manoeuvring of the aircraft in yaw, pitch and roll and for hover and forward and backward flight. Where propulsion units (52-55) are pivoted to arms (56), the arms (56) of fore and aft propulsion units (52, 54; 53, 55) are intercoupled via chain drives (57-60) or linkages (61). The wing-structure (1; 51; 78) may have fins (47;84), slats (81) and flaps (82) and other aerodynamic control-surfaces, and enlarged strakes (84) may incorporate rudder surfaces (80). Just one propulsion unit (21) may be mounted at each extremity of the wing-structure (22), and additional fan units (48, 83) may be used for augmenting lift and for yaw control.
Abstract:
The Spring flying device (1) preferably of circular, oval or polygon shape, capable of vertical take-off and landing, comprises the source (5) of flowing medium (6), which flows through chamber (2) consisting of curved bottom face generating buoyancy during flow (3) and curved top medium attracting face (4). The faces (3) and (4) making up chamber (2) have adequate spacing from each other which allows their interaction still; control is provided by deflection (9) and swivelling (10) flaps, pivot-mounted in chamber (2) and acting upon the flowing medium (6). The device (1 ) may carry missile ramp (18) with protective guide shield (14) with horizontal (15) and radial (16) deflection flaps which streamline the missile exhaust gases (17) to outer top buoyancy face (12), while the missile exhaust gases (17) may be streamlined to apertures (19) of the chamber simultaneously.

Abstract:
Takeoff and landing modes are added to a flight control system of a Vertical Take-Off and Landing (VTOL) Unmanned Air Vehicle (UAV). The takeoff and landing modes use data available to the flight control system and the VTOL UAV's existing control surfaces and throttle control. As a result, the VTOL UAV can takcoff from and land on inclined surfaces without the use of landing gear mechanisms designed to level the UAV on the inclined surfaces.
