摘要： An over-pressure vent (OPV) system is provided for a fuel tank of an aircraft. The OPV system includes an OPV valve configured to be coupled in fluid communication with a supply line of a nitrogen enriched air distribution system (NEADS) such that the OPV valve is configured to vent pressure from the supply line. The OPV valve is configured to be coupled in fluid communication with the supply line upstream from an outlet of the supply line from which the NEADS delivers nitrogen enriched gas to the fuel tank. The OPV valve is configured to sense a pressure within the supply line upstream from the outlet of the supply line.

摘要： An aircraft fuel system including at least one fuel tank, a source of inerting gas, an inlet for introducing the inerting gas into the at least one fuel tank, and a vent system arranged to allow the inward and outward venting of air from the fuel tank. In embodiments, the vent system includes a vent, an inward vent pressure valve disposed between the vent and the at least one fuel tank and configured to enable the at least one fuel tank to increase by a predetermined pressure over ambient air pressure, and an outward vent pressure valve disposed between the at least one fuel tank and the vent and configured to enable the at least one fuel tank to decrease by a predetermined pressure below ambient air pressure.

摘要： Fuel tank inerting systems and methods for aircraft are described. The systems and methods include controlling of (i) a first reactant control element, (ii) a second reactant control valve, (iii) a ram air control valve, (iv) a driving mechanism, and (v) a flow control valve, to control a state of a fuel tank inerting system. The states of the fuel tank inerting system include an OFF state, a CIRCULATE state, a PRIME state, a CATWARM state, an ON state, a DEPRESSURIZE state, and a COOLDOWN state, wherein the states are determined in part by a prior state and/or a position/actuation of a given element of the system.

摘要： A liquid tank system comprises a main liquid tank, an outlet communicating between a fluid circuit and the main liquid tank, an inlet communicating between the fluid circuit and the main liquid tank, and an auxiliary cavity. First vent passage and second vent passage(s) communicate between the main liquid tank and the auxiliary cavity and allows liquid and gas to flow from the main liquid tank to the auxiliary cavity. The second vent passage has a flow control device regulating flow through the second vent passage and having a set point at which it allows liquid and gas to flow from the main liquid tank to the auxiliary cavity only when a pressure in the main liquid tank is beyond a threshold. The liquid tank system has an attitude envelope in which the liquid tank system is configured such that, in use, the flow control device blocks flow through the second vent passage when an end of the first vent passage in the main liquid tank is above a liquid level, and the flow control device allows gas and/or fluid flow through the second vent passage when main fluid tank pressure is above the threshold and the end of the first vent passage in the main liquid tank is below the liquid level.

摘要： Methods and systems for distributing an inert gas to an aircraft fuel tank are provided herein. The method includes channeling the inert gas in a first direction via a first distribution line and channeling the inert gas in an opposite second direction via a second distribution line. The second distribution line is concentrically aligned with and circumscribes the first distribution line. The second distribution line includes a termination point within the aircraft fuel tank. The second distribution line defines a plurality of distribution orifices that release of the inert gas into an ullage space of the fuel tank.

摘要： A hydraulic damping apparatus comprising a conduit for a hydraulic fluid having a port in a wall of the conduit; a resonator having a chamber and a neck, the neck being arranged to provide fluid communication between the chamber and the port. The apparatus further comprises a first pressure sensor arranged to sense pressure in the conduit upstream of the port, a second pressure sensor arranged to sense pressure in the conduit downstream of the port, and a controller configured to determine the amplitude of a pressure fluctuation sensed by the first pressure sensor and the amplitude of a pressure fluctuation sensed by the second pressure sensor. The controller is further configured to vary a resonant frequency of the resonator in accordance with a difference between the amplitude of the pressure fluctuation sensed by the first pressure sensor and the amplitude of the pressure fluctuation sensed by the second pressure sensor.
