Abstract:
A neutrally buoyant airship, such as a blimp, contains a lifting body which allows the airship to remain neutrally buoyant in air and a fuel cell located in the airship. A method of generating power in the neutrally buoyant airship, comprising providing a fuel and a oxidizer to a solid oxide fuel cell to generate power, and providing heat from the fuel cell to a remotely located lifting body, wherein the lifting body allows the airship to remain neutrally buoyant in air.
Abstract:
An airship system according to the invention has an airship (110), a base station (120), and at least three measurement points. The airship (110) emits ultrasonic waves upon receiving an instruction from the base station (120). Measurement point units (S1-S3) receive the ultrasonic waves, and thereby measure distances from the airship (110) to the respective measurement points. An MPU that is incorporated in the base station (120) calculates a position of the airship (110). The base station (120) controls a route of the airship (110) based on the calculated position by sending a flight instruction to the airship (110). In this manner, an airship system can be provided that makes it unnecessary for an operator to pilot the airship and that can reduce the load weight and the power consumption of the airship.

Abstract:
An airship has a generally spherical shape and has an internal envelope for containing a lifting gas such as Helium or Hydrogen. The airship has a propulsion and control system that permits it to be flown to a desired loitering location, and to be maintained in that location for a period of time. In one embodiment the airship may achieve neutral buoyancy when the internal envelope is as little as 7% fall of lifting gas, and may have a service ceiling of about 60,000 ft. The airship has an equipment module that can include either communications equipment, or monitoring equipment, or both. The airship can be remotely controlled from a ground station. The airship has a solar cell array and electric motors of the propulsion and control system are driven by power obtained from the array. The airship also has an auxiliary power unit that can be used to drive the electric motors. The airship can have a pusher propeller that assists in driving the airship and also moves the point of flow separation of the spherical airship further aft. In one embodiment the airship can be refuelled at altitude to permit extended loitering.
Abstract:
A hybrid airship such as an unmanned drone or UAV (10, 110, 210) capable of significantly extended flight times can use one of two technologies, or both together. The first technology uses a combination of a lifting gas (such as hydrogen or helium) in a central volume (12) or balloon and multirotor technology (13. 14) for lift and maneuvering powered by batteries (25). The second technology equips the airship with an on board generator (30) to charge the batteries (225) during flight for extended flight operations, with an internal combustion engine, such as a high power to weight ratio gas turbine engine (32), driving the generator. A quadcopter or other multicopter configuration is desirable.
Abstract:
According to embodiments described in the specification, a hover attachment includes a housing operable to receive a mobile device having a processor, a memory, and a display, at least one sensor operable to detect a position parameter of the mobile device relative to an object under tracking, and a regulator operable to maintain, responsive to the detecting, the mobile device in a hover relation to the object under tracking, wherein the display of the mobile device is a situational display. An exemplary method includes providing a situational display interface on a display of a mobile device mounted in a hover attachment, detecting a movement of an object under tracking in hover relation to the mobile device, and when the detected movement is associated with a position change function, controlling the hover attachment to maintain the hover relation between the mobile device and the object under tracking.
Abstract:
The disclosed embodiments include a trailer for an autonomous vehicle controlled by a command and control interface. The trailer includes a trailer body configured to retain the autonomous vehicle in an undeployed configuration. The trailer also anchors the autonomous vehicle in a deployed configuration. A tether is provided having a first end coupled to the trailer body and a second end that is configured to couple to the autonomous vehicle. A winch is utilized to adjust a length of the tether to move the autonomous vehicle between the undeployed configuration and deployed configuration. Further, a communication system communicates with the command and control interface and the autonomous vehicle to control movement of the autonomous vehicle between the undeployed configuration and deployed configuration.
Abstract:
A hybrid VTOL vehicle having an envelope configured to provide hydrostatic buoyancy, a fuselage attached to the envelope and having at least one pair of wings extending from opposing sides thereof to produce dynamic lift through movement, and a thrust generation device on each wing and configured to rotate with each wing about an axis that is lateral to a longitudinal axis of the envelope to provide vertical takeoff or landing capabilities. Ideally, the envelope provides negative hydrostatic lift to enhance low-speed and on-the-ground stability.
