The present invention relates to a glide bomb and methods of use thereof for use with an unmanned or manned aerial vehicle or for operative deployment. In one form, the glide bomb is configured to be carried and released by an unmanned aerial vehicle (“UAV”) for flight towards a selected target. The glide bomb includes an elongate body having a nose and an opposed tail aligned along a longitudinal axis; a payload; a pair of wings extendable from opposed sides of the body for producing lift, said wings configured to be selectively moveable between a retracted position and an extended position; and two or more tail control surfaces operatively associated with the tail of the body for at least pitch and yaw control.

An example of an aerial vehicle includes a rudder removably connected to the aerial vehicle by a twist lock mechanism. The twist lock mechanism is biased in a locked position by an elastic member.

A foldable aerial vehicle may take the form of a flying wing. The flying wing includes port and starboard wings having port and starboard root and tip portions. The port and starboard root and tip portions are hinged one to another so that the span axes of all of the root and tip portions are parallel in the stowed condition and so that the tip portions are separated by the root portions in the deployed condition to define the flying wing. The wings are not symmetrical about the longitudinal axis of the vehicle, with the span axes of the root and tip portions being stepped from one wing tip to the other. Folding winglets are disposed on opposing wing tips, with the higher winglet extending in an upward direction and the lower winglet extending in the downward direction.

Towed aerodynamic platforms approach the behavior of flat plate airfoils to achieve high lift-to-drag (L:D) performance when operated at low pitch angles. A lead aircraft may tow multiple platforms to form train units. Low form drag and high L:D enable solar aircraft that are more robust and faster than approaches extending wingspan rather than extending the length of the aerial train. Applications extend beyond solar aircraft and include vehicles towed along an overhead monorail system and aerial drones.

A vertical take-off and landing (VTOL) unmanned aerial vehicle having a foldable fixed wing and a twin-ducted fan power system (7) arranged at a tail portion of a fuselage in a transverse and tail propulsion arrangement provides lift for vertical take-off and landing and propulsion for horizontal flight. By means of deflection of a control servo plane arranged at a duct exit, a vectored thrust is provided to enable a fast attitude change. When the aerial vehicle takes off and lands vertically/flies at a low speed, the wing is folded to reduce the frontal area exposure to crosswind. When the aerial vehicle is flying horizontally, the wing is expanded to obtain larger lift. A Coanda effect is created at a trailing edge of the wing by suction of the duct to improve performance.

An expanding pin system is described that can provide automated and/or power controlled locking and unlocking of an expanding pin assembly in a mechanical joint. For example, the expanding pin system can include an actuation assembly that includes a single actuator (e.g., motor) to control an expanding pin assembly for locking and unlocking a mechanical joint.

Disclosed is an aircraft and a method of controlling an aircraft. The aircraft comprises a continuous wing assembly extending from port to starboard sides of the aircraft. The aircraft is controlled partially by flexing portions of the wing, and partially or totally by mechanical systems that alter the position of a fuselage with respect to the wing. The fuselage is attached to the wing by a wing/fuselage joint structure that permits at least two mutually orthogonal axes of rotation of the fuselage relative to the wing. The aircraft includes a sensors, a telemetry system linked to a remote server, and a control system for programming flight information and aircraft control instructions and a plurality of actuators responsive to the control system for rotating the fuselage relative to the wing and flexing the wing for controlling the flight of the aircraft in response to instructions from the control system.

A rigid-flexible coupled unmanned aerial vehicle (UAV) morphing wing and an additive manufacturing method thereof are disclosed. A shape memory alloy (SMA) strip/wire for controlling the wing upward deformation and an SMA strip/wire for controlling the wing downward deformation are arranged alternately, and a plurality of reinforcing ribs are arranged at intervals on the SMA strips/wires for controlling the wing upward deformation and the SMA strips/wires for controlling the wing downward deformation. The SMA strips/wires for controlling the wing upward deformation and the SMA strips/wires for controlling the wing downward deformation are arranged on a flexible substrate, and are wrapped with an insulating covering. The SMA strips/wires for controlling the wing upward deformation and the SMA strips/wires for controlling the wing downward deformation each are provided with an electric heating element.

An electric VTOL aeronautical apparatus is disclosed that has folding wings each having an inboard wing portion coupled to an outboard portion via a hinge. Folding wings are known to be used during flight, although using a motor to fold and unfold the wings. In the present disclosure, the motor with its concomitant weight and complication is obviated or reduced by making the rotational axis of the hinge such that end of the hinge on the leading edge of the wing is displaced more outboard and lower than the end of the hinge on the trailing edge to allow the wing to fold and unfold passively. When in forward flight, a folded wing has more of the underside of the wing facing the flow, which pushes the wing upward, i.e., unfolding the wing. When the aeronautical apparatus transitions to vertical flight, gravity pulls the wings downward into the folded position.

An unmanned aerial vehicle launch tube that has a tube, a sabot disposed in an interior of said tube, said sabot having a first clasp tab, and a clasp detachably coupled to said first clasp tab and contacting an inner circumferential wall of said tube so that said clasp is rotationally constrained by the inner circumferential wall and said first clasp tab.
