PROBLEM TO BE SOLVED: To provide an unmanned rotary wing vehicle in an unmanned air transportation vehicle. SOLUTION: A rotary wing vehicle includes a body structure having an elongated tubular backbone or core, and a counter-rotating coaxial rotor system having rotors with each rotor having a separate motor to drive the rotors about a common rotor axis of rotation. The rotor system is used to move the rotary wing vehicle in a directional flight. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
Drohnen benötigen für die Durchführung von Betriebs- und Flugphasen einen Start- und Landeplatz. Bedingt durch die Leichtbauweise sind Drohnen zudem empfindlich gegen äußere Einflüsse wie z.B. extreme Wetterschwenkungen und Verschmutzungen. Ein Bediener ist für den Betrieb und den Schutz der Drohne erforderlich. Die neuartige Vorrichtung bietet neben einem sicheren Start- und Landeplatz auch Schutz vor äußeren Einflüssen ohne dass ein Bediener anwesend sein muss. Die Vorrichtung verfügt in ihrem Inneren über eine Plattform (Fig.1./Nr.3.), auf der die Drohne (Fig.2./Nr.4.) aufsetzen und parken kann. Zur Freigabe der Plattform öffnet die Vorrichtung die Dachkonstruktion (Fig.l./Nr.l) mit einer 180° Drehung um die Unterschale (Fig.1./Nr.2.). Auf der so freigegebenen Plattform kann die Drohne aufsetzen und bis zum nächsten Start parken. Nach Landung schließt die Vorrichtung die Dachkonstruktion durch eine weitere 180° Drehung der Dachkonstruktion. Die Drohne kann selbsttätig mit der Vorrichtung kommunizieren, um Start- und Landevorgänge durchzuführen. Die Vorrichtung ist vor allem dort von Vorteil, wo Drohnen ohne Anwesenheit eines Bedieners Betriebs- und Flugphasen absolvieren sollen, wie z.B. in abgelegenen oder gefährlichen Gebieten. Zudem besteht der Vorteil, dass Drohnen neue Einsatzgebiete anfliegen können und vor Ort eine geeignete Lande- und Versorgungsmöglichkeit vorfinden.
Abstract:
A transportable ground station for a UAV includes a container in which the UAV may be transported and housed. The container includes a wireless or contact-based recharging station that recharges the UAV's batteries or other power sources after the UAV returns from a mission. The recharging station may be directly or indirectly connected to one or more solar panels that generate energy to power the recharging station. The ground station may be deployed virtually anywhere, from any vehicle (e.g., plane, train, boat, truck, etc.), and may operate over an extended period of time without human intervention.

Abstract:
A vehicle, especially a maritime vessel, is provided with an autogyro drawn by a tether. The tether contains mechanical strengthening components that enable it to securely retain the autogyro to the vehicle. The tether also contains two electrical conductors carrying different phases of AC power to the autogyro, and four optical fibers carrying optical data signals to and from the autogyro electronic payloads and avionics control circuitry. Signal converters at ends of the tether convert a wide range of electrical or wireless signals to optical data signals for transmission along the tether, and then back into the original electrical signal format for use by the autogyro or vehicle electronics.
Abstract:
Line capture devices for unmanned aircraft, and associated systems and methods are disclosed. A system in accordance with a particular embodiment includes a line capture device body having a line slot with an open end and a closed end. A retainer is positioned proximate to the line slot and has a rotor with a plurality of rotor arms positioned to extend at least partially across the line slot as the rotor rotates relative to the body. A joint rotatably couples the rotor to the body, and a ratchet device is operably coupled to the rotor to allow the rotor to rotate in a first direction and at least restrict the rotor arm from rotating in a second direction opposite the first. In other embodiments, the retainer can include other arrangements, for example, one or more wire-shaped elements.

Abstract:
Methods and apparatuses provide surveillance of a convoy. At least one unmanned aerial vehicle (UAV) obtains images around the convoy's position to provide information about potential hostile activity while the UAV follows a generally curvilinear path around the convoy as instructed by one of the convoy vehicles. Path planner algorithm software is executed by the controlling convoy vehicle in which position and velocity information regarding the unmanned aerial vehicle and the convoy are processed to determine values of control variables. The determined values are sent to the unmanned aerial vehicle over a wireless communications channel. The path of the surveillance vehicle may be changed in order to provide evasive measures to avoid an attack on the surveillance vehicle by an adversary.
