摘要:
Methods, apparatus, and articles of manufacture to control and monitor a folding wingtip actuation system are disclosed. An example apparatus includes a collection module to obtain flight stage information of an aircraft. The example apparatus further includes a sequence and control module to calculate a first position of a folding wingtip assembly operatively coupled to a wing of the aircraft, determine actions during a first stage and a second stage to complete in sequence to move the folding wingtip assembly, determine a status of a component of the folding wingtip assembly based on a measurement of a sensor, and control a movement of the folding wingtip assembly in accordance with the actions and based on the status.

An unmanned aerial vehicle with deployable components (UAVDC) is disclosed. The UAVDC may comprise a fuselage, at least one wing, and at least one control surface. In some embodiments, the UAVDC may further comprise a propulsion means and/or a modular payload. The UAVDC may be configured in a plurality of arrangements. For example, in a compact arrangement, the UAVDC may comprise the at least one wing stowed against the fuselage and the at least one control surface stowed against the fuselage. In a deployed arrangement, the UAVDC may comprise the at least one wing deployed from the fuselage and the least one control surface deployed from the fuselage. In an expanded arrangement, the UAVDC may comprise the at least one wing telescoped to increase a wingspan of the deployed arrangement.

A vertical take-off and landing aircraft with tiltable power for use on land and in the air includes: a body (3) provided with a drive device; wheels (8) being controlled to make the body move on the ground; and a front thruster (1) and a rear thruster (2) controlling the body to fly or take off/land, wherein transmission brace rods (5) are arranged on both sides of the body, and a first pivot (9) passes transversely through the body and is connected to the transmission brace rods on both sides of the body; wherein the front thruster is fixed on front ends of the transmission brace rods, and the rear thruster is fixed on rear ends of the transmission brace rods; wherein the central axes of the front and rear thrusters are perpendicular to the plane formed by the two transmission brace rods. By controlling a tilting angle of the front/rear thrusters, this aircraft has two basic functions of vertical take-off/landing and horizontal flight, so as to facilitate conversion between land travel and air flight. During flight in the air, the aircraft body always remains in horizontal state, thereby making the occupants feel comfortable and providing them with broad vision so as to operate the aircraft safely.

An apparatus and methods for changing the shape of a wing using a plurality of morphing structures. One example method includes coupling a plurality of morphing structures to each other. Each morphing structure includes an anchor, a plurality of hinges, a plurality of shape-memory alloy members wherein each shape-memory alloy member extends from the anchor to a different hinge, a plurality of springs wherein each spring extends from the anchor to a different hinge, and a plurality of rigid members wherein each rigid member extends between two hinges. The method further includes actuating the plurality of shape-memory alloy members in at least some of the morphing structures wherein the shape-memory alloy members contract when actuated to pull against the hinges and anchors within the actuated morphing structures to rotate the rigid members and change the shape of the actuated morphing structure.
摘要:
A solar powered aircraft having segmented wings that can be reconfigured during flight to optimize collection of solar energy are described. The aircraft have rigid construction that is resistant to inclement weather and is configured to rely on free flight control at high altitude and under conventional conditions, thereby providing flight duration in excess of 2 months. The aircraft is particularly suitable for use as part of a telecommunications network. A telecommunications network incorporating such aircraft is also discussed.
