  • Patent number: 7618008
    Abstract: Nowadays in aircraft on-board inert gas generation systems (OBIGGS) are used to generate inert gases. Cooled bleed air of engines or auxiliary turbines is fed to said OBIGGS systems. According to an embodiment of the present invention, an air supply device for an OBIGGS system in an aircraft is proposed that comprises a bleed position (1,2). By way of the bleed position (1,2), air from an air conditioning unit (4,5) on board the aircraft can be bled and can be fed to the OBIGGS system. There is thus no need for an additional heat exchanger and an additional ram-air channel. Maintenance expenditure and air resistance are thus reduced.

  • Patent number: 7546981
    Abstract: Drain masts of commercial aircraft need to be heated in order to prevent freezing caused by the low outside temperatures when the aircraft travels at a corresponding altitude. An exemplary embodiment described in the application pertains to a drain system for an aircraft that can be used for draining liquids or gases from the aircraft or for drawing air into the aircraft. In this case, the liquids or gases are heated by means of a coolant that receives its thermal energy from a thermal or electrochemical process being carried out on board the aircraft. Consequently, the waste heat produced by the thermal or electrochemical process being carried out on board the aircraft, for example, a fuel cell process, can be carried off outboard via the drain system. In addition, the coolant can be advantageously utilized for cooling the thermal or electrochemical process.

  • Patent number: 7407131
    Abstract: The present invention blocks and/or attenuates the upstream travel of acoustic disturbances or sound waves from a flight vehicle or components of a flight vehicle traveling at subsonic speed using a local injection of a high molecular weight gas. Additional benefit may also be obtained by lowering the temperature of the gas. Preferably, the invention has a means of distributing the high molecular weight gas from the nose, wing, component, or other structure of the flight vehicle into the upstream or surrounding air flow. Two techniques for distribution are direct gas injection and sublimation of the high molecular weight solid material from the vehicle surface. The high molecular weight and low temperature of the gas significantly decreases the local speed of sound such that a localized region of supersonic flow and possibly shock waves are formed, preventing the upstream travel of sound waves from the flight vehicle.

  • Patent number: 7395761
    Abstract: The Variable-Force Payload Ejecting System, residing within an air vehicle, utilizes multiple pressure generators, one or more of which may be activated, to produce variable levels of force. A controlling computer within the air vehicle determines when and how much pressure needs to be generated to eject a given item, such as a submunition, from the vehicle. In its determination, the computer factors in the vehicle's forward velocity and height over the intended target at the time of ejection and the characteristics of the particular submunition to be ejected. An activating mechanism activates one or more pressure generators to produce the determined amount of pressure. The pressure thusly generated acts on an inflatable tube that inflates and expels the selected submunition. The result is a more precise delivery of the submunitions onto the intended targets.

  • Publication number: 20020088901
    Abstract: A drainmast (10) for discharging liquid from a moving aircraft (12). The drainmast (10) includes a fairing (20) having a mounting flange (24), a flow-controlling cap (26), and an aerodynamically advantageous mast (28) extending therebetween. The flow-controlling cap (26) has a lower surface defining an airflow-redirecting zone, a liquid-release zone, and a liquid-recirculation zone. The redirecting zone is shaped to redirect airflow (A) into the release zone in a direction parallel to the discharge direction (D) of the drain tube (22). The release zone is shaped to encourage the redirected airflow (Aredir) to sweep a substantial portion of the released liquid away from the fairing in a primary flow path (L). The recirculation zone captures escaped liquid from the release zone and recirculates this escaped liquid back into the release zone in recirculation flow path (Lrec1). The rear and side surfaces of the cap (26) may include a continuous groove (66) aligned with the airflow direction A.

  • Patent number: 6264142
    Abstract: The improved helicopter anti-icing and deicing system and method includes mounting an airfoil shaped manifold transversely of the helicopter and filling the manifold with anti-icing or deicing fluid which is not under sufficient pressure to spray outwardly from the manifold. Instead, the rear edge of the manifold is provided with small, spaced openings which cause fluid droplets to form along the rear edge of the manifold and to then drop downwardly by gravity. The helicopter is positioned above a power line with the power line extending in the direction of the helicopter longitudinal axis and droplets are caused to exit the manifold as the helicopter flies along the power line.

  • Patent number: 6192990
    Abstract: In one aspect, the invention is directed towards a helicopter-carried firefighting device including a valve. The valve has an outer assembly and an inner assembly in which the outer assembly has a reduced surface area on those surfaces which are disposed normally to a direction of movement. The outer assembly therefore may be less affected by hydrostatic and hydrodynamic forces directed so as to oppose its movement. The valve may be located in a reservoir of fluid, and controlled by a control head operated remotely from the helicopter so as to release fluid from the reservoir over a fire. The valve may be symmetrical about a longitudinal axis of the valve, such that transversely directed fluid flows through the valve may be cancelled, producing a coherent, longitudinal fluid flow. The valve may be opened partially so as to operate as a metering valve. The valve may be closed relatively rapidly to retain fluid in the reservoir so as to permit multiple dumps from a single reservoir if so desired.

  • Patent number: 6125942
    Abstract: A fire fighting system uses a bucket suspended from a helicopter to deposit fire retardant onto a fire from an opening in the bottom of the bucket. The bucket has a predetermined configuration and a valve for controlling the area of an opening through which the retardant is deposited when the bucket is suspended from the helicopter. A suitable mechanism, such as an electrically driven valve actuator, varies the area of the opening to deposit the retardant at a volume flow rate as a desired function of time while the helicopter flies along a drop line. The mechanism varies the area of the opening in accordance with a schedule determined before discharge is begun according to the configuration of the bucket, the flow characteristics of the opening as the valve changes the area thereof, and the initial amount of the retardant material in the bucket.

    Abstract: An apparatus and method are disclosed for the aerial spraying of agricultural chemicals with improved spray deposition and reduced drift. The spraying apparatus includes two oppositely charged sets of spray nozzles which may be fitted onto an aircraft. Both sets include one or more nozzles having spraying tips which produce a hollow cone spray pattern, and at least the tips of these nozzles are constructed of a substantially non-conducting material. Cylindrical electrodes are positioned concentric to the nozzle tips for inducing an electrostatic charge upon liquid spray emitted from the nozzles. The electrodes are in turn connected to high voltage power supplies, with the electrodes corresponding to the first nozzle set being connected to a power supply of opposite potential than the electrodes corresponding the second nozzle set. Consequently, the spray issuing from the nozzle sets will be oppositely charged.
