Abstract:
An autonomous stratospheric unmanned airship with an operating altitude from 5-22 km and with a multi-month operational cycle. Spheroid rigid geodesic frame of constant volume formed by a multitude of struts, with an outer envelope enclosing the frame defining the eigenfrequency spectrum of the airship above 20 Hz, with vibrational amplitudes between 0.1 and 1 cm. Independently controllable electrical propulsion units, attached to the frame in the horizontal plane passing through the center of mass, can change the direction and value of the thrust vector. Buoyancy is controlled with a system integrated inside the geodesic frame including buoyant fluid pressurized tanks, valves for the release of the buoyant fluid through the buoyant fluid conduit into the buoyant gas cell which fills the geodesic frame. Valves at the subsystem support platform enable ambient atmosphere to fill the internal volume of the frame not occupied by the buoyant gas cell.
Abstract:
Disclosed embodiments relate to a combined shipping container and balloon deployment system for deploying balloons into a balloon network. Such a shipping container may allow one or more balloons to be transported to a desired launch location, and then launched directly from the shipping container.
Abstract:
An automated mobile vehicle configured to autonomously provide coverage for inoperable infrastructure components at various locations. A plurality of automated mobile vehicles may be deployed to provide emergency lighting, a wireless network, audio, video, etc., at an event area. The event area may be indoors and/or outdoors.
Abstract:
Embodiments include one or more high altitude, long endurance (HALE) unmanned aircraft (110) capable of persistent station-keeping having one or more electromagnetic (IR/Visual/RF) sensor elements or suites (112, 337) for purposes of survey and/or signal gathering. Embodiments include one or more high altitude, long endurance (HALE) unmanned aircraft (110) capable of persistent station-keeping having a directable laser (331). Embodiments include a group of four or more high altitude, long endurance (HALE) unmanned aircraft (611-614) configured as GPS repeaters.
Abstract:
A sonar buoy includes a fuselage having a tube-like shape, one or more wings coupled to the fuselage, an engine coupled to the fuselage and operable to propel the sonar buoy through flight, and a guidance computer operable to direct the sonar buoy to a predetermined location. The sonar buoy further includes a sonar detachably coupled to the fuselage and forming at least a part of the fuselage, and a rocket motor detachably coupled to the fuselage. The one or more wings are operable to be folded into a position to allow the sonar buoy to be disposed within a launch tube coupled to a vehicle and to automatically deploy to an appropriate position for flight after the sonar buoy is launched from the launch tube. The rocket motor propels the sonar buoy from the launch tube and detaches from the fuselage after launch.
Abstract:
A lightweight, man-portable weapon delivery system includes a fuselage, and first and second wings mounted to opposing sides of the fuselage. The system includes an electric motor for driving a propeller for providing thrust to propel the system. The electric motor is mounted to the fuselage, and configured to be remotely started by a user. The system includes an imaging device mounted to the system and configured to capture images of a theater of operations of the system. The system includes a communication circuit in communication with the imaging device and configured to transmit the images from the imaging device to the user for viewing the theater of operations of the system for remotely steering the system. The communication circuit is configured to receive commands from the user for steering the system into the target. The system includes a payload configured to store the ordnance.
Abstract:
The invention relates to an autonomous stratospheric aircraft which is lighter than air, and to a method for providing radio and optical communication, television broadcasting and monitoring with the aid of communication equipment arranged on the aircraft. The present invention can be used for producing lighter-than-air aircraft as well as global and regional communication and television broadcasting and multi-aspect monitoring systems and networks.
Abstract:
A span-loaded, highly flexible flying wing, having horizontal control surfaces mounted aft of the wing on extended beams to form local pitch-control devices. Each of five spanwise wing segments of the wing has one or more motors and photovoltaic arrays, and produces its own lift independent of the other wing segments, to minimize inter-segment loads. Wing dihedral is controlled by separately controlling the local pitch-control devices consisting of a control surface on a boom, such that inboard and outboard wing segment pitch changes relative to each other, and thus relative inboard and outboard lift is varied.
Abstract:
A flying micro-rotorcraft unit is provided for remote tactical and operational missions. The unit includes an elongated body having an upper and a lower end. The body defines a vertical axis. The unit further includes a navigation module including means for determining a global position of the elongated body during flight of the unit. Rotor means of the unit is coupled to the upper end of the elongated body for generating a thrust force that acts in a direction parallel to the vertical axis to lift the elongated body into the air. The rotor means is located between the elongated body and the navigation module.
