Abstract:
A ducted fan air vehicle and method of operation is disclosed for obtaining aerodynamic lift and efficiency in forward fliglit operation without significantly impacting hover stability. One or more retractable wings (301) are included on the ducted fan air vehicle and are deployed during forward flight to provide aerodynamic lift. The wing or wings are retracted when the vehicle hovers to reduce the impact the wings have on stability in a wind. Each wing may conform to the curvature or profile of the vehicle when retracted, and may be constructed in one or more wing sections. The wing or wings may be deployed and retracted automatically or at the command of an operator. Each wing and related components may be integrated into the vehicle or may be detachable.
Abstract:
Die Erfindung betrifft ein Verriegelungssystem, insbesondere für Komponenten eines Hubschraubers, das Folgendes aufweist: ein Zentralteil (10) mit mehreren Anschlagselementen (11); zwei oder mehr Ausleger (20), die an dem Zentralteil angelenkt oder mit diesem lösbar verbunden sind; ein in den Zentralteil zumindest teilweise einführbares und von diesem lösbares Verschlussteil (30), wobei Zentralteil und Verschlussteil derart geformt sind, dass bei einer Dreh- und/oder Verschiebebewegung die beiden Teile und die Ausleger mechanisch derart ineinander greifen, dass der Ausleger zwischen dem Anschlagelement des Zentralteils und dem Verschlussteil arretiert werden kann.
Abstract:
An air-launched aircraft (10) includes deployable wings (16, 18), elevons (20, 22), and vertical fins (26, 28) that deploy from a fuselage (12) during flight. The aircraft may include a control system for operating the elevons, a communication system, and batteries for powering the systems. In addition, the aircraft may include a payload module (14) that mates with an interface in the fuselage. The payload module may include any of a variety of payloads, including cameras, sensors, and/or radar emitters. The aircraft may be powered or unpowered, and may be very small, for example, less than on the order of 10 kg (22 pounds). The deployable surfaces of the aircraft may be configured to deploy in a pre-determined order, allowing the aircraft automatically to enter controlled flight after being launched in a tumbling mode.

Abstract:
Methods and apparatuses for assembling, launching, recovering, disassembling, capturing, and storing unmanned aircraft (140) and other flight devices or projectiles are described. In one embodiment, the aircraft (140) can be assembled from a container (111) with little or no manual engagement by an operator. The container (111) can include a guide structure to control motion of the aircraft components. The aircraft (140) can be launched from an apparatus that includes an extendable boom (103). The boom (103) can be extended to deploy a recovery line (853) to capture the aircraft (140) in flight. The aircraft (140) can then be returned to its launch platform, disassembled, and stored in the container (111), again with little or no direct manual contact between the operator and the aircraft (140).
Abstract:
Die Erfindung bezieht sich auf ein Luftfahrzeug mit faltbaren und/oder schwenkbaren Tragflügeln. Eine zwischen den Flügelteilen und/oder dem Rumpf angreifende Gasdruckfeder mit starker Enddämpfung sorgt für eine schnelle und automatische Entfaltung bzw. Schwenkung der Tragflügel.
