Abstract:
An aerial delivery system including a ram-air parachute, one or more recovery parachutes, a mantle removably attached to a cargo, and a controller operably connected to the mantle, the ram-air parachute, and the one or more recovery parachutes. The controller may be configured to receive location information associated with a target, receive information related to an ambient condition, determine a recovery parachute opening point based on the target information and the ambient condition, and cause a navigation of the aerial delivery system to the determined recovery parachute opening point.
Abstract:
The proposed UUAV provides a small, agile vehicle that leverages the unique principals of remote controlled model aviation. The UUAV also encompasses an aerodynamically shaped, gas filled wing that can be used to provide buoyancy for lift assistance both through the use of the lighter than air gas and by its aerodynamic shape in forward flight.
Abstract:
A novel design and construction method for an inflatable, rigidizable wing for a terrestrial or planetary flying vehicle. The wing is caused to deploy from an initially packed condition and to assume its functional shape by means of an inflation gas. After inflation, the wing is rigidized by any of several means, such that the inflation gas is no longer required. The composite wing is fabricated from a base reinforcement material, often a fabric, which is coated with a polymer resin that hardens when exposed to a curing mechanism. Several activation mechanisms exist by which to initiate rigidization of such a structure, including elevated temperature, ultraviolet light, and chemical constituents of the inflation gas. The resultant wing has fundamental advantages compared to existing inflatable wings, including improved stiffness, and reduced susceptibility to structural failure in response to puncture.
Abstract:
A hollow elliptical-cylindrical hull conformingly houses a hollow rectangular-prismatic cabin whereby the four longitudinal parallel outside edges of the latter make contact with the inside surface of the former. The fully constructed aircraft (either non-powered or powered) includes the integral hull-plus-cabin structure along with nose, tail and airfoil structures that are coupled therewith. The cabin conformingly accommodates hollow rectangular-prismatic modules useful for cargo storage. While the nose and/or tail structure is uncoupled from the integral hull-plus-cabin structure, the modules are inserted into the cabin and the cabin is sealed. The aircraft is lifted (e.g., via airplane, helicopter, rocket or balloon) to a particular elevation and released, whereupon the two wings fully emerge and the aircraft effects controlled flight until reaching its destination. After landing, the nose and/or tail structure is uncoupled from the integral hull-plus-cabin structure, the cabin is unsealed, and the modules are removed from the cabin.
Abstract:
The Duffel Bag Airplane is an inflatable flying wing unmanned airborne vehicle (UAV). The fuselage will house everything but the wings. The wing can be rolled up around the fuselage into a small package when deflated for easy transportation, such as by being carried in a duffle bag. Fabric construction, a small internal combustion engine with cooled exhaust, and wing warping controls combine to make the airplane inexpensive and extremely stealthy. All the usual signatures have been suppressed, which allow it to be used to make observations from close range under combat conditions. Control of this airplane is accomplished by warping the wings and is supplemented with stability augmentation.
Abstract:
A powered remotely piloted vehicle which is not controllable at the low landing speeds necessary for landing on a platform of small area is provided with a para-foil type wing deployable at the beginning of a recovery sequence, and is further provided with a rocket ejectable line which is passed to the landing platform and winched in so that the composite flight vehicle and deployed para-foil wing is drawn towards the platform after the manner of a kite.
Abstract:
Die Erfindung betrifft ein Luftfahrzeug (1), umfassend eine Rumpfeinheit (2) und zumindest eine aufblasbare Tragflächeneinheit (3), welche im nicht aufgeblasenen Zustand in der Rumpfeinheit (2) angeordnet ist und durch Aufblasen aus der Rumpfeinheit (2) heraus in eine Tragflächenstellung positionierbar ist. Erfindungsgemäß ist die zumindest eine Tragflächeneinheit (3) im nicht aufgeblasenen Zustand in die Rumpfeinheit (2) eingerollt und durch Aufblasen aus der Rumpfeinheit (2) ausrollbar.
Abstract:
L'invention concerne un procédé de transport pendulaire aérien sécurisé par un aéronef téléporteur. Il se caractérise en ce qu'on choisit ledit aéronef (1) téléporteur équipé d'une voilure souple (2) et conçu apte au décollage et à l'atterrissage sur des terrains non aménagés, qu'on prépare une mission comportant au moins un cheminement entre un point de départ et un point d'arrivée, qu'on charge sur un support de mission les paramètres géographiques de ladite mission dans les trois dimensions de l'espace, et qu'on effectue, par des moyens de lecture conçus aptes à communiquer avec un calculateur autopilote embarqué conçu apte à agir sur des actionneurs de commandes de vol que comporte ledit aéronef (1), la lecture des paramètres de ladite mission sur ledit support de mission, et qu'on procède au démarrage dudit aéronef (1) pour l'exécution de ladite mission. L'invention concerne encore un aéronef (1) téléporteur pour la mise en oeuvre de ce procédé.
Abstract:
An orientation system is disclosed for a lighter-than-air aircraft having a lower stage suspended from an envelope. The orientation system includes cords interconnecting the envelope and the lower stage and means for adjusting the length of at least one of the cords between the lower stage and the envelope. Adjusting the length produces a shift in the angle of attack of the envelope with respect to the lower stage.
