Abstract:
The invention relates to aviation namely to flying vehicles adapted to ride on an air cushion and to effect a take-off and landing on aerodromes of any category. The goal of the invention is to design a flying vehicle capable of aerodynamically efficient flight both at low and high level flight, as well as take-off and landing from non-prepared aerodromes and from water under the conditions of stabilization and movement control of all flight regimes. The goal is achieved due to the fact that in a flying vehicle comprising a fuselage in the form of a carrying wing, a power installation, a take-off and landing air cushion device, a gasodynamic system of boundary layer control, a device for controlling the position of flow leaving the trailing edge as well as stabilization and flight control systems, the take-off and landing air cushion device consists of a propelling slot nozzle (12) and side skegs (17) between which are mounted rotatable flaps (21, 22, 23) controlling the flight of the vehicle and regulating the position of the pressure centre on the bottom. The fuselage has the form of a cylindrical segment conjugating at its sides with spherical fairings.

Erfindungsgemäß ist vorgesehen, dass die Tragstruktur (12) eine Mehrzahl von Stab- oder Rohrabschnitten (24-30) aufweist, die eine kreisförmige, ovale oder polygonale Hauptspannebene für die Hülle (10) definieren.
Abstract:
The present invention is a variable geometry aircraft that is capable of morphing its shape from a symmetric cross-section buoyant craft to an asymmetric lifting body and even to a symmetric zero lift configuration. The aircraft may include variable span, length, and camber. The variability of the structure and the flexible envelope allows the aircraft to adjust its aspect ratio along with the camber of the upper and/or lower surfaces to achieve varying shapes. This transformation changes both the lift and drag characteristics of the craft and may be accomplished while the craft is airborne.
Abstract:
Изобретение относится к области авиации, в частности к конструкциям летательных аппаратов. Комбинированный летательный аппарат содержит аэростат с жестким каркасом, баллонетами с гелием, подвесную систему, несущую платформу с грузопассажирской кабиной. Кабина включает органы управления, двигатели, электрооборудование и измерительные приборы. Аэростат составлен из двух оболочек, связанных цилиндрическим шарниром и имеющих фиксаторы, управляя поворотом которых изменяют и фиксируют аэростат в виде крыла или в виде Λ-образной фигуры с раскрывшимся обтекателем. Подвесная система включает жесткие и гибкие связи и выполнена с возможностью трансформации и фиксации. Двигатели установлены с возможностью изменения направления векторов тяги на 360° в вертикальной плоскости и фиксации. Базирование и фиксация устройства в устойчивом положении может осуществляться на твердой земной поверхности с уклоном, на водной поверхности или на вертикальном сооружении. При базировании на поверхности с уклоном несущая платформа крепиться к анкерам, а оболочки аэростата поворачиваются вниз до касания с поверхностью. При базировании на воде оболочки повернуты вниз до погружения их части в воду. При базировании на вертикальном сооружении на окончании передней оболочки дополнительно устанавливаются причальные крюки, крепящиеся к анкерам.
Abstract:
An airship or airborne station comprises a gas-containing envelope for containing a lifting gas, solar panels on the envelope for providing electric power to an energy storage system, and an external display screen powered by the energy storage system. This airship or airborne station enables novel methods of using the airship or airborne station to display digital content, to sell or auction ad space on the display screen to the highest bidder, to display information for events, crowds, rescue operations, or to interact digitally with a group of wireless communications devices. Furthermore, the airship or airborne station acts as a communication and media hub for uploading user-generated content, relaying communications from wireless devices, broadcasting content or interactive media.
Abstract:
Systems, method, devices and apparatus are provided for reducing drag and increasing the flight efficiency characteristics of aircraft and airships including hybrid aircraft utilizing distributed boundary layer control and propulsion means. Boundary layer control includes passive systems such as riblet films and boundary layer propulsion means includes a divided and distributed propulsion system disposed in the curved aft sections of aircraft and airships including hybrid aircraft susceptible to boundary layer drag due to degree of curvatures, speed and density of the surrounding air. Distributed propulsion propulsion means includes constructing propellers and riblets from shape memory alloys, piezoelectric materials and electroactive polymer (EAP) materials to change the shape and length of the distributed propulsion means.
Abstract:
A method and system for air flight is disclosed. A blended lifting body system is comprised of a lift module, a propulsion module, a payload module and a control system. The control system morphs the other modules through variable buoyancy, internal structures and a flexible exterior, and varies bio-mimetic oscillation in the propulsion module in order to facilitate takeoff, flight and landing.

Abstract:
A Lighter-than-Air Airship with self-sealing capability, comprising a semi-rigid hull, reinforced by capsule shaped tubes, supported within the structure by lightweight frames, and blocked from moving by a separating frame. Space in front of this forms another compartment providing an aerodynamic facia, additional cargo loading ability: and a suitable location for piloting. All compartments/tubes are filled with lighter-than-air gas. The Airship uses "ball and socket" type landing gear. Features can include counter-acting flaps, a new design of propeller engine with capacity for centre-less propellers, and an explosive anchoring system enabling the Airship to land, unload, and lift-off quickly without taking on ballast. The combined functions of flaps and engines permit use as a rudderless craft. It incorporates an integral, longitudinal cargo/passenger unit, which can be separable and have optional mechanism to vary its position to the Airship.
Abstract:
An aircraft comprising an envelope (6) that is inflatable with a lifting gas that is lighter than air that, at least when inflated has curved upper and lower surfaces. The aircraft has a payload carrying means (5), and an aerodynamic lifting means (8) for creating a vertical annular flow of air that induces a flow of air over the respective upper or lower surface (12, 14) of the envelope (6.). One form of aerodynamic generator (8) comprises a plurality of aerofoil blades (20) mounted for rotation around a periphery of the envelope (6).
