Abstract: An aircraft spoiler mechanism includes a spoiler fore-section, a spoiler aft-section, and a reverse-motion linkage arm. The spoiler fore-section includes a forward end, a hinge end, an actuator coupling, and a pivot coupling to couple to a wing structure of an aircraft to enable rotation of the spoiler fore-section relative to the wing structure. The spoiler aft-section includes a hinge portion coupled to the hinge end of the spoiler fore-section and a crank-arm. The reverse-motion linkage arm includes a first end, a second end, and a pivot point coupled to the forward end of the spoiler fore-section. The spoiler mechanism also includes a first linkage to couple the first end of the reverse-motion linkage arm to the wing structure and a second linkage coupled to the second end of the reverse-motion linkage arm and to the crank-arm on the spoiler aft-section.

Abstract: A method for designing and operating an aircraft nose landing gear wheel-mounted electric taxi system to move aircraft with optimal torque during a broad range of ground travel conditions. Electric taxi system components may be sized to produce optimal ground travel torque to move aircraft during the majority of aircraft ground travel conditions and operated to produce a maximum or breakaway torque to move the aircraft with the electric taxi system when a higher level of torque is required. Turning the nose landing gear wheels to a selected angle or through a range of angles simultaneously as the electric taxi system is operated produces the breakaway torque required to get the aircraft moving. When lower torque is needed, the aircraft may be driven with the nose landing gear wheels parallel to the longitudinal axis to produce optimal torque for electric taxi system-powered aircraft ground travel.

Abstract: The present invention relates to a method, system, and apparatus of flight system for individual users using electric ducted fans. The flight system comprises a modular unit, which comprises a plurality of electric ducted fans, means for connecting electric ducted fans, and a pair of armpit supports. The flight system further comprises means for securing a modular unit around respective left and right shoulders of a user. In one embodiment, the flight system can be controlled to generate a horizontal acceleration of 20 MPH/second and a vertical acceleration of 10 MPH/second.

Abstract: An assembly for deployment and retraction of a panel for outer space environment usage, includes a member secured to the panel with the member having an axis of rotation. Mass component connected to the panel, with panel wrapped about member with mass component positioned a first radial distance from the axis of rotation. Mass component has a mass per unit area greater than a mass per unit area of the panel adjacent to the mass component. With a rate of rotation of the mass component and member being same, the mass component rotates about the axis of rotation at a second radial distance from the axis of rotation, wherein the second radial distance is greater in dimension than the first radial distance. With a rate of rotation of the mass component and the member changed to be different, radial distance of the mass component to the axis of rotation decreases.
