Abstract:
A helium assisted kite system is a kite having an inflatable gas chamber that is attached to the perimeter of the kite cover fabric and outlines its shape. The cover fabric has at least one sleeve that a perimeter rail slides into to provide rigidity and shape to the kite. A frame having a spine, a top spreader, and a bottom spreader are attached to the cover fabric by a series of nocks. The inflatable gas chamber is filled with helium which provides lift for the kite on windless days and is able to lift the kite to a height where it reaches the higher elevation winds.
Abstract:
An air vehicle has a gas-filled hull of a flexible sheet material. Strakes extend along an exterior of the hull, each strake comprising a gas-filled tube of a sheet of a flexible sheet material. A rigid board extends outwardly from the gas-filled tube and away from the vehicle. A further sheet of a flexible sheet material extends from one side of the strake over the board to another side of the strake, to provide a strake that is generally triangular in cross section.
Abstract:
An aerial vehicle comprises an elongate envelope within which are at least one first compartment for holding a lighter than air gas and at least one second compartment for holding atmospheric air and said at least one second compartment having an inlet and an outlet and at least one pair of wings extending laterally from the envelope; said wings being planar units with a leading and trailing edge, the width of the wings from their leading edges to their trailing edges being substantially less than the length of the envelope with airfoil portions fitted between the leading and trailing edges of the wing: the top and bottom of the wings are mirror images of one another; in which forward motion of the vehicle is obtainable without trust through alternate diving and climbing motion.

Abstract:
Systems, method, devices and apparatus are provided for reducing drag and increasing the flight efficiency characteristics of aircraft and airships including hybrid aircraft utilizing distributed boundary layer control and propulsion devices. Boundary layer control includes passive systems such as riblet films and boundary layer propulsion devices having a divided and distributed propulsion system disposed in the curved aft sections of aircraft and airships including hybrid aircraft susceptible to boundary layer drag due to degree of curvatures, speed and density of the surrounding air. Distributed propulsion devices include constructing propellers and riblets from shape memory alloys, piezoelectric materials and electroactive polymer (EAP) materials to change the shape and length of the distributed propulsion device.
Abstract:
An unmanned aircraft, unmanned aviation system and method for collision avoidance during the flight operation of an unmanned aircraft are provided. The unmanned aircraft includes a lift and propulsion system and a flight control system having a flight control unit, a navigation system and an actuator system. The flight control unit has an autopilot unit. The flight control unit calculates control commands using data from the navigation system and/or the autopilot unit, which can be conveyed to the actuator system for actuating the lift and propulsion system. A collision warning system is connected with the flight control system, the collision warning system detects a collision situation and makes collision avoidance data available. A connection between the collision warning system and the autopilot unit is provided, in order to initiate an obstacle avoidance maneuver by the autopilot unit with the help of the collision avoidance data.
Abstract:
Provided is a positive-pressure floating type airplane comprising an airfoil portion, left-right fuselages, a central fuselage, an elevator and a rudder disposed at the back of the airfoil portion, a thruster disposed at the back of the central fuselage, and a horizontal stabilizer disposed at the rear ends of the left-right fuselages. The individual front ends of the airfoil portion, the left-right fuselages and the central fuselage are formed into arcuate shapes in longitudinal sections. On the lower side of the airfoil portion, a recessed air capture is formed from the front end to the rear end. As a result, the positive-pressure floating type airplane is floated by the reaction from the air at the time when the air to pass the air capture through the airfoil portion is pushed by the thrust of the thruster, and is propelled forward by the component of that thrust.
Abstract:
An airship comprises a shell having a bi-convex shape, wherein the shell encompasses a volume, and a gas storage system located within the volume.
Abstract:
