Abstract: A tether system for providing thrust to or power subsystems of an artificial satellite in a low earth orbit. The tether has three main sections, an insulated section connected to the satellite, a conducting section connected to the insulating section for drawing in and releasing electrons from the space plasma and a non-conducting section for providing a tension to the other sections of the tether. An oxygen resistant coating is applied to the bare wire of the conducting section as well as the insulated wires of the insulated section that prevents breakdown during tether operations in the space plasma. The insulated and bare wire sections also surround a high tensile flexible polymer core to prevent any debris from breaking the tether during use.

Abstract: An arrangement and a method are proposed for the generation of water on board an aircraft with the use of one or more fuel cells, whereby low-temperature fuel cells are provided as fuel cells. It is proposed that several single-cell or few-cell fuel cells may form a fuel-cell panel or cell array and several cell panels or cell arrays may be arranged close to the inside of the aircraft fuselage and the cathode side of the at least one fuel cell has a chamber pointing to the exterior of the aircraft for the condensation of the water contained in the air and the anode side has a chamber carrying a combustion gas, for example hydrogen. With the proposed solution, a reduction in the storage capacity for drinking water and its quality-assured provision may be enabled and moreover, with the use of fuel cells as a virtual power station, the energy demand on engine generators, auxiliary power unit (APU) or ram air turbine (RAT) may be reduced.

Abstract: This disclosure relates to a method of limiting the yawing motion on the trajectory of an artillery shell during the firing phase using a sliding driving band and completely folded-in guide fins. The shell is converted as soon as possible outside the mouth of the barrel of the firing piece by fold-out of the guide fins into a fin-stabilized artillery shell. Any form of non-uniform fin fold-out is avoided by virtue of all the guide fins being interconnected to form a system which gives all the fins the same movement pattern and the same fold-out speed in each phase of fin fold-out. This disclosure also includes a shell in which synchronization of fin fold-out includes a rotatable control ring that is arranged around the axis of the shell and is connected to the rotation spindles of all the fins.

Abstract: A method of launching and retrieving a UAV (Unmanned Aerial Vehicle) (10). The preferred method of launch involves carrying the UAV (10) up to altitude using a parasail (8) similar to that used to carry tourists aloft. The UAV is dropped and picks up enough airspeed in the dive to perform a pull-up into level controlled flight. The preferred method of recovery is for the UAV to fly into and latch onto the parasail tow line (4) or cables hanging off the tow line and then be winched back down to the boat (2).

The hybrid airship may function as an airborne military communications relay platform.

Abstract: A retaining clamp for alignment of risers when packing a parachute is disclosed. The retaining clamp comprises a base with three prongs defining bores for receiving and engaging large rings of three-ring release assemblies (three-ring release assemblies are used for cutting off the main parachute canopy in the event of malfunction before deploying the secondary parachute in order to avoid entanglement between the main and secondary parachutes). The large rings are inserted in the bores, turned and engaged with the bores by way of force of friction. An alternative embodiment of the retaining clamp comprises a base with two prongs defining a bore for receiving and engaging large rings of three-ring release assemblies. Both embodiments can be used in combination with a parachute folding mat.

Abstract: A system and process for countering the vibrations induced in an aircraft by the windmilling of an engine fan may produce a first electric flight control command for a servocontrol to use in actuating a control surface of the aircraft. The servocontrol is slaved to the first electric flight control command, and the servocontrol's operation is limited to a reduced frequency band. Vibrations induced by the windmilling of the engine fan are monitored, and, when the monitored vibrations exceed a threshold, a second electric flight control command for application to the servocontrol is computed to oppose the induced vibrations. Also, the first and second electric flight control commands are summed to produce an overall control command for the control surface, and the servocontrol is temporarily slaved to the overall control command for operation in a widened frequency band.

Abstract: A hybrid airgun includes a compressed gas chamber; a barrel; a firing valve between chamber and barrel; a secondary cylinder divided into front and back volumes by a secondary piston, the front volume connected to the chamber; a liquefied gas chamber connected to the back volume; a valve for transferring liquefied gas into the liquefied gas chamber; a cocking mechanism; and a firing mechanism. The cocking mechanism fills the compressed gas chamber with a compressed first gas, and/or transfers a liquefied second gas into the liquefied gas chamber. The firing mechanism opens the firing valve. During flow of the first gas into the barrel, pressure exerted by the second gas in the back volume moves the secondary piston and partially disengages it from the secondary cylinder, thereby enabling the second gas to flow into the compressed gas chamber, through the firing valve, and into the barrel.

In particular, the novel arrangement allows passengers to easily and comfortably switch between sitting and sleeping positions. The arrangement provides for multiple compartments arranged transversely with respect to the longitudinal dimension of the aircraft. Each compartment includes a stair and multiple, individual passenger accommodation units arranged one above another on each side of the stair. Each unit contains structure which allows a passenger to switch between a sitting position, in which the passenger is supported on a seat surface, and a fully reposed position in which the passenger is supported on a substantially flat, horizontal sleeping surface.

Abstract: This invention relates to a parachute supported aircraft having a frame and a seat for supporting at least a pilot. A parachute is coupled to the frame by a plurality of riser lines for allowing the parachute to inflate and form a wing for lifting the frame. A pair of upwardly extending masts are coupled to the frame. Each mast supports a vertically displaceable sleeve receiving a group of riser lines. Control cables connected to a winch raise and lower the sleeves to allow the pilot to selectively collapse and inflate the wing in a controlled fashion. A wing elevating cord can be used by the pilot to help pull the parachute from a generally vertical, partially inflated, lockout position into a generally horizontal, more inflated, flight position.
