  • Patent number: 10450957
    Abstract: A gas turbine engine includes a rotor section proximate to a combustor section, where the rotor section is subject to bowing effects due to thermal differences and heat transfer at engine shutdown. The gas turbine engine also includes a heat pipe system. The heat pipe system includes one or more heat pipes installed between an upper portion of the rotor section and a lower portion of the rotor section. The heat pipe system is operable to accept heat at a hot side of the heat pipe system at the upper portion, flow heat from the hot side to a cold side of the heat pipe system, and reject heat from the cold side of the heat pipe system at the lower portion to reduce a thermal differential between the upper portion and the lower portion at engine shutdown.

  • Patent number: 8336610
    Abstract: A device for temperature control in an aircraft cabin includes a first supply control arrangement and a first pressure control arrangement. The first supply control arrangement includes an air duct and a valve arrangement that controls a supply of heated air delivered to a first temperature area of the aircraft cabin such that a first specified temperature for the first temperature zone is achieved. When the valve arrangement fails, the first pressure control arrangement operates to control a pressure of heated air supplied into the first temperature area such that the first specified temperature for the first temperature zone is achieved.

  • Patent number: 8201775
    Abstract: The invention relates to a decompression element for pressure equalization in a cabin of an aircraft, with a decompression element frame, a flap, and a hinge element or at least one bearing element for fitting the flap to the decompression element frame. The hinge element or the bearing element can be produced from a plastics material. A decompression device for decompressing a cabin area includes a decompression device frame, a first opening which enables a flow to take place between a line of an air-conditioning system of the aircraft and the interior space of the decompression device, a second opening which enables a flow to take place between the cabin area and the interior space of the decompression device, and a third opening receiving the decompression element with the flap.

  • Patent number: 7727057
    Abstract: The invention relates to a device (10) for heating an aircraft cabin and comprises a first hot air supply line (12) that leads to an air conditioning unit (14), a flow control valve (16) that is disposed in the first hot air supply line (12) upstream from the air conditioning unit (14), and a second hot air supply line (18) that branches off from the first hot air supply line (12) between the flow control valve (16) and the air conditioning unit (14) and bypasses the air conditioning unit (14). In order to assure air conditioning of the aircraft cabin in the event of a failure of the air conditioning unit (14) a third hot air supply line (20) branches off from the first hot air supply line (12) upstream from the flow control valve (16), which third hot air supply line (20) connects the first hot air supply line (12) to the second hot air supply line (18).

  • Patent number: 7119700
    Abstract: A combined smoke detector and cooling control system for a mobile platform is operable to control multiple electronic units. A smoke detector is connected to the electronic unit and operates to identify a smoke event. A cooling system is connected to the electronic unit. A fan in the cooling system includes a switch which indicates if a cooling system fault occurs. A plurality of relays connect to the electronic unit, the smoke detector and the cooling system. If a cooling system fault occurs, a first relay immediately de-energizes the cooling system. After a fixed period of smoke persistence during a smoke event, a second relay de-energizes the cooling system.

  • Patent number: 6786279
    Abstract: A forward in flight entertainment system (IFE) which allows air to be directed to and exhausted from the IFE equipment in isolation from the cabin conditioned air. Further, potential IFE generated smoke may be kept isolated from the cabin air. The forward IFE equipment is located in forward sections of the aircraft system switching from ground to air mode is accomplished through air/ground signal 10 responsive to landing gear truck tilt. Once the air/ground transition from ground mode to air mode has occurred, ventilation valves 1 and 2 will be closed and the heated air will be exhausted overboard by forward IFE cooling overboard valve 4 whose overboard flow increases with altitude and cabin to ambient pressure differential.

  • Patent number: 6389826
    Abstract: In an air conditioning system for an aircraft, two pre-mixing units respectively mix cold air from two air conditioning units with recirculated fuselage interior air from two recirculation units, to prepare two pre-mixed air flows that are both directed into and mixed together in a common air distribution mixing chamber, from which mixed air distribution lines branch off to respectively associated separate air conditioning zones within the fuselage. Post-mixing units are respectively interposed in the mixed air distribution lines and respectively mix additional quantities of recirculated fuselage interior air into the mixed air distribution lines. Thereby, the admixture of recirculated air is divided into at least two stages, the system provides redundant failure tolerant operation, and the danger of ice formation in the air lines is reliably prevented even while the air conditioning units provide cold air at a temperature below the water freezing point.
