摘要:
A method for operating an unmanned aerial vehicle (UAV) system includes directing a first, multi-rotor carrier aircraft (101) to carry a second, carried aircraft (121) aloft, and release the second aircraft for flight, while powering the first aircraft with an on-board battery, directing the first aircraft to position a capture line (106) in a flight path of the second aircraft and capture the second aircraft.
摘要:
A flight control apparatus for fixed-wing aircraft includes a first port wing and first starboard wing, a first port swash plate coupled between a first port rotor and first port electric motor, the first port electric motor coupled to the first port wing, and a first starboard swash plate coupled between a first starboard rotor and first starboard electric motor, the first starboard electric motor coupled to the first starboard wing.

摘要:
An aircraft is provided with a gas turbine engine having a plurality of shafts. A first shaft provides power to an electrical generator and a propeller, while a second shaft provides power to a refrigeration system. The refrigeration system may be integrated to the propeller, like a ducted fan, or on the outer skin of the aircraft.
摘要:
A control system configured to control an acceleration of an air vehicle which comprises a tiltable propulsion unit that is tiltable to provide a thrust whose direction is variable at least between a general vertical thrust vector direction and a general longitudinal thrust vector direction with respect to the air vehicle, the control system comprising: (a) an input interface for receiving information indicative of a monitored airspeed of the air vehicle; and (b) a control unit, configured to issue controlling commands to a controller of the tiltable propulsion unit for controlling the acceleration of the air vehicle
摘要:
An unmanned high altitude aircraft, in particular a stratosphere aircraft, comprising at least one fuselage (10), wings (13, 14), control surfaces (13", 14", 20', 20", 21', 21") and at least one drive device (15, 16, 17) that has at least one drive machine and at least one propeller (15', 16' 17'), is characterised in that each wing (13, 14) has a plurality of tubes (40, 41, 42, 43, 44) and wing spars (46' 46") that extend in one direction transversally, preferably perpendicularly, to the longitudinal axis of the fuselage (Z) and are surrounded by a skin that forms a wing covering (45) and defines the cross-sectional contour of the wing, the cross-sectional contour forming a laminar profile that generates high lift when there is low flow resistance. Each wing (13, 14) is provided with a winglet (13', 14') that extends transversally to the longitudinal axis of the wing on its free end which faces away from the fuselage (10), and the winglet (13' 14') is provided with a movable control surface (13", 14") that enables an aerodynamic side force to be generated in order to bring the aircraft into an oblique bank position.
摘要:
Die Erfindung betrifft einen Bausatz (104) und ein Herstellverfahren zum Herstellen eines unbemannten Luftfahrzeugs (10) mit einem maximalen Startgewicht von wenigstens 250kg, wobei der Bausatz (104) eine Rumpfstruktur (13) mit einer Auftriebserzeugungsstrukturbefestigungsschnittstelle (24) zur Befestigung einer Auftriebserzeugungsstruktur (14) und weiter eine erste Auftriebserzeugungsstrukur (14a) und eine unterschiedliche zweite Auftriebserzeugungsstruktur (14b) aufweist, wobei die erste und die zweite Auftriebsstrukturerzeugungsstruktur (14a, 14b) jeweils eine gleich ausgebildete Rumpfstrukturbefestigungsschnittstelle (25) zur Befestigung an der Auftriebsstrukturerzeugungsschnittstelle (24) der Rumpfstruktur (13) aufweist.
