L'invention concerne un drone volant (1) comprenant : - un fuselage (2) ; - des moyens de propulsion alimentés au moins par des accumulateurs électriques et/ou des cellules photovoltaïques (3) ; - une première aile portante (4) définie par une envergure et par une superficie de face supérieure, la face supérieure de la première aile portante étant essentiellement recouverte de cellules photovoltaïques, caractérisé en ce qu'il comprend une deuxième aile portante (5) présentant une envergure et une superficie de face supérieure sensiblement identiques à celles de la première aile portante, la deuxième aile portante étant décalée le long du fuselage et en hauteur par rapport à la première aile portante, la face supérieure de la deuxième aile portante étant essentiellement recouverte de cellules photovoltaïques.
Abstract:
An aircraft, in particular an unmanned aerial vehicle with wing-borne flight mode and hover flight mode, comprises a wing structure (4) having a left (6), middle (7), and right wing section (8). A support structure extends from the wing structure (4), and has an upper and lower support section. Each one of the left and right wing section (6, 8), and upper and lower support section (18, 20) has a thrust unit (10, 12, 22, 24). Left and right wingtip sections are rotatable relative to a left and right wing base section, respectively, around an axis extending substantially in a lengthwise direction of the wing structure. The thrust units (10,12) of the left and right wing sections(6, 8) are provided at the respective wingtip sections, in particular at the extremities thereof.
Abstract:
The invention discloses a hand-launched unmanned aerial vehicle, and belongs to the technical field of unmanned aerial vehicles. The hand-launched unmanned aerial vehicle comprises a body, a tail, at least one power source and a lens bin, wherein the body comprises a middle section, a first side section and a second side section; two sides of the middle section are respectively detachably connected with the first side section and the second side section correspondingly; the tail is fixed to the middle section; the power source is fixed to the middle section; and the lens bin is fixed to the middle section and provided with a flexible cushion. The invention overcomes the technical defects in the prior art that the body maintenance cost of the hand-launched unmanned aerial vehicle is high and the lens bin is very likely to be damaged due to collision between the lens bin of the hand-launched unmanned aerial vehicle and the ground.
Abstract:
Die Erfindung betrifft ein senkrechtstartfähiges Fluggerät (10) mit einem Schubantrieb (31) zum Erzeugen einer in eine Horizontalrichtung (1) wirkenden Antriebskraft und einem Hubantrieb (32) zum Erzeugen einer in eine Vertikahichtung wirkenden Auftriebskraft. Das Fluggerät weist ferner einen Motor (12) zum Bereitstellen von mechanischer Energie für den Schubantrieb (31) und einen ersten Generator (11) zum Bereitstellen von elektrischer Energie für den Hubantrieb (32) auf. Zudem weist das Fluggerät einen Abgasturbolader (40) für den Motor (12) mit einer von einem Abgasstrom (44) des Motors (12) angetriebenen ersten Turbine (41) auf, die dazu ausgeführt ist, mechanische Energie für den Schubantrieb (31) bereitzustellen.
Abstract:
A hybrid VTOL vehicle having an envelope configured to provide hydrostatic buoyancy, a fuselage attached to the envelope and having at least one pair of wings extending from opposing sides thereof to produce dynamic lift through movement, and a thrust generation device on each wing and configured to rotate with each wing about an axis that is lateral to a longitudinal axis of the envelope to provide vertical takeoff or landing capabilities. Ideally, the envelope provides negative hydrostatic lift to enhance low-speed and on-the-ground stability.
Abstract:
The present invention relates to an aircraft comprising a fuselage (100) comprising a fuselage axis (101), a first wing arrangement (110) and a second wing arrangement (120). The first wing arrangement (110) is mounted to the fuselage (100) such that the first wing arrangement (110) is tiltable around a first longitudinal wing axis (111) of the first wing arrangement (110) and such that the first wing arrangement (110) is rotatable around the fuselage axis (101). The second wing arrangement (120) comprises at least one propulsion unit (122), wherein the second wing arrangement (120) is mounted to the fuselage (100) such that the second wing arrangement (120) is tiltable around a second longitudinal wing axis (121) of the second wing arrangement (120) and such that the second wing arrangement (120) is rotatable around the fuselage axis (101). The first wing arrangement (110) and the second wing arrangement (120) are adapted in such a way that, in a fixed-wing flight mode, the first wing arrangement (110) and the second wing arrangement (120) do not rotate around the fuselage axis (101). The first wing arrangement (110) and the second wing arrangement (120) are further adapted in such a way that, in a hover flight mode, the first wing arrangement (110) and the second wing arrangement (120) are tilted around the respective first longitudinal wing axis (111) and the respective second longitudinal wing axis (121) with respect to its orientations in the fixed-wing flight mode and that the first wing arrangement (110) and the second wing arrangement (120) rotate around the fuselage axis (101).
Abstract:
The self-sustaining drone aircraft freight and observation system (5) comprises a fleet of jet-powered drone aircraft (10) designed to carry freight (12) only. The drones (10) operate from a separate airfield in outlying areas to decrease land costs and to avoid disturbing residential and business areas. Navigation is automated using guidance from GPS satellites (16), and the aircraft (10) can be assisted by a hydraulic catapult (13) during takeoff to reduce the fuel payload. The observation component (18) includes sensors that can observe weather conditions and emergency signals from boats, ships and other sources. The system (5) may include a large-scale energy production center and multi-acre vegetable, herb and flower production center (26). The energy production center includes solar panels (30), fuel cells (38), and batteries (44). Thus, the system (5) does not need to be connected to the public utility electrical grid.
Abstract:
Packaging (10) for consumer goods having a discontinuous tactile coating (16) is provided. The discontinuous tactile coating (16) is formed by applying one or more varnishes (18) to the outer surface of the packaging (10) in a pattern comprising a plurality of raised features having a height of at least about 10 microns and a separation of at least about 20 microns. In a preferred embodiment, the discontinuous tactile coating is formed by applying one or more tinted varnishes to the outer surface of the packaging.
