The UAV having a collapsible wing section which can be easily removed from the fuselage, allowing for quick assembly and disassembly and ease of portability. The unmanned aerial vehicle includes a primary wing assembly, a fuselage, a means for propelling the unmanned aerial vehicle, and means for remotely controlling the unmanned aerial vehicle. The primary wing assembly includes a wing having a center spar and two outwardly diverging side spars. The wing also has a pliable flexible material supported by the center spar and the at least two outwardly diverging side spars. The pylon is connected to the wing and supports the wing. The fuselage is connected to the pylon such that the pylon extends away from the fuselage and spaces the wing a distance from the fuselage. The fuselage includes a tail having a rudder located along a trailing edge and elevators located along the trailing edge.
Abstract:
An aircraft which is designed for remote controlled slow flight, indoor or in a small outdoor yard or field. The aerial lifting body is defined by a series of lightweight planar or thin airfoil surfaces (A1, A2, A3, A4) arranged in a radially symmetrical configuration. Suspended within the cavity (O) formed by the thin airfoil surfaces (A1, A2, A3, A4) is a thrust generating propeller system (C) that is angled upwardly and that can be regulated remotely so as to change the angle of the thrust vector within the cavity (O) for steering. Lifting, stability, turning, and general control of the direction of motion in flight is accomplished without any formal wings, rudder, tail, or control surfaces.
Abstract:
A remote-control powered parafoil aircraft has an aircraft body (1) that is engine powered and hung with lines (2) from an air-expandable wing (3, 30). The lines include control lines (15) with which air flow and aerodynamic shape of the air-expandable wing are variable selectively from a foil controller (18, 19, 20) on the aircraft body for flight-mode control. Sight from a television camera (8) on the aircraft body is televised to a control unit (9) from which control data is transmitted selectively from proximate the control unit to the foil controller (14) with a multi-axis joystick or similar control, to an engine (6) on the parafoil body from an engine controller (24) and to an item servo (29) for control of optional items (45) on the aircraft body.
Abstract:
Apparatus and method for recovering and arresting an aircraft or other vele. A boom is swivelly connected to a support structure via braking mechanism. The boom is pivotally connected to the brake mechanism such that it can also pivot in a second, different plane intersecting the plane of rotation of the brake mechanism. A shear pin prevents pivoting of the boom in the second plane until the boom has experienced a predetermined load in that plane. The distal end of the boom distant from the brake mechanism is provided with structure for engaging the aircraft. When the aircraft is flown at and captured by the boom, the weight and motion of the aircraft breaks the shear pin, causing the boom to move in the second plane until engaged by a stop. This rapid change in position of the engaging end of the boom in the second plane prevents the aircraft from pendulating about the boom. Forward motion of the aircraft also causes movement within the brake mechanism in the first plane which absorbs the kinetic energy of the aircraft as the boom swivels against the brake mechanism, so that the aircraft is slowed and arrested.

Abstract:
An aerial surveillance device (100) is provided, comprising an image capturing device (150.) capable of being supported by an airframe structure (200) above the ground. The airframe structure includes a body portion (300) defining a longitudinal axis and configured to support the image - capturing device. A tail portion (400) having control surfaces (425,450) is operably engaged with the body portion along the axis. Transversely- extending wing portions (800, 850) are directly engaged with the body portion. Each wing portion is defined by longitudinally-opposed spars (800A, 800B, 850A, 850B) extending from a spaced-apart disposition at the body portion to a common connection (800C, 850C) distally from the body portion. The spars have a fabric extending therebetween to provide a wing surface. A support member (900, 950) extends along an aerodynamic center, transversely to the body portion, of each wing portion, to tension and rigidify the wing portions so as to provide a positive camber for the wing portions and to form an airfoil.
Abstract:
The invention provides a system, method and landing device for landing an aircraft (50) with respect to a predetermined landing location (P). The aircraft is configured for powered flight at least when the parafoil (60) is deployed, and includes an automatic landing system for controllably executing a landing approach maneuver for the aircraft while in free powered flight with the parafoil deployed to enable the aircraft to be brought into overlying proximity with the landing location. A landing device in the form of an energy absorbing landing net arrangement (20) is provided at the landing location for enabling the aircraft to be landed thereon at least partially vertically when in overlying proximity, and for dampening the landing impact of the aircraft.
