摘要： A method for controlling thermal conductivity between two thermal masses includes thermally contacting a first conduction body with a heat source, thermally contacting a second conduction body with a heat sink, and thermally contacting the second conduction body with the first conduction body by moving the first conduction body between a first position and a second position with a thermal expansion component. The thermal expansion component moves the first conduction body between the first position and the second position at a predetermined temperature and heat is conducted from the heat source to the heat sink through the first and second conduction bodies.

摘要： A heat exchanger manifold configured to receive or discharge a first fluid includes a primary fluid channel and a plurality of secondary fluid channels. The primary fluid channel includes a fluid port and a first branched region distal to the fluid port. The plurality of secondary fluid channels are fluidly connected to the primary fluid channel at the first branched region. Each of the plurality of secondary fluid channels includes a first end and a second end opposite the first end. Each of the plurality of secondary fluid channels extends radially from the first branched region at the first end and has an equal length from a center of the first branched region to the second end.

摘要： A system for cooling a motor operating within an aircraft system includes an enclosure receiving ram air from a first ram air duct and discharging ram air to a second ram air duct to form a cooling path. The second ram air duct is discrete and independent from the second ram air duct. The system can discharge ram air between a heat exchanger and a fan within the second ram air duct that define a reduced or negative pressure region within the second ram air duct.

摘要： A method for monitoring degradation of at least one component in a power system comprising a motor drive circuit configured to provide AC power from a power source to power a motor. The method includes isolating the motor drive circuit from the power source; injecting a test signal to at least one component of the isolated motor drive circuit; and measuring a propagated signal resulting from the injected test signal propagating through the at least one component. The propagated signal may be compared to a test signal and, if the propagated signal differs from the test signal by a threshold, then degradation of the at least one component may be identified.

摘要： A single stage servo valve assembly includes a drive assembly and a valve body assembly. The valve body assembly defines: a valve body extending along a valve body axis between a first valve body end and a second valve body axis: a supply port; a control port; and a return port formed through the valve body each defining a respective fluid flow channel, having a fluid flow axis, providing fluid communication between an interior of the valve body and an exterior of the valve body. The drive assembly operates to control the flow of fluid between the supply port, the control port and the return port, via the interior of the valve body, in response to an electric command signal. Each of the supply port, and the return port includes a tapered nozzle at an interface between the interior of the valve body and the respective port fluid flow channel.

摘要： An environmental control system for a vehicle includes an environmental control system pack including a ram air circuit and a thermodynamic device. The ram air circuit includes a ram air shell having a ram inlet and a ram outlet and at least one ram air heat exchanger arranged within the ram air shell. A ram air fan is fluidly coupled to the ram air shell. A bypass conduit is fluidly connected to a source of compressed medium. The bypass conduit has an outlet end positioned adjacent to a surface of the ram air fan for delivering a compressed medium to the surface.

摘要： An air processing system for an aircraft comprising a hydrogen fuel cell. The air processing system includes an input airflow; a first and a second compressor, wherein each compressor is configured to compress the airflow in a compression stage; a first and a second turbine, wherein each turbine is configured to decompress the airflow in a decompression stage; and a first and a second shaft each configured to independently rotate. Each shaft mechanically couples one of the compressors and one of the turbines, such that torque can be transferred between the compressor-turbine pair.

摘要： An annular water removal system (AWRS) for an air cycle environmental control system (ECS) includes a line replaceable unit (LRU) configured to output air flow, and a water collector coupled to the LRU. The water collector includes an upper portion and a lower portion. The upper portion includes a coalescing unit having a collector inlet to receive the air flow and configured to coalesce moisture from the air flow output from the LRU. The lower portion includes a collection unit in fluid communication with the coalescing unit. The collection unit is configured to collect the moisture coalesced by the coalescing unit.

摘要： A pressure vessel includes a first component, a second component, and a bonded lap joint between the first and second components. The bonded lap joint includes a portion of the first component which extends about a circumference of the pressure vessel, a portion of the second component which extends about the circumference of the pressure vessel and partially overlaps the portion of the first component, an adhesive bond connecting the portion of the first component to the portion of the second component and thereby joining the first and second components, and mechanically interlocking structures connecting the portion of the first component to the portion of the second component. The adhesive bond forms a primary retention mechanism. The mechanically interlocking structures are situated at least partially within each of the portion of the first component and the portion of the second component, and form a secondary retention mechanism.

摘要： An environmental control system includes a rotary machine, a first bypass duct, and a first check valve in the first bypass duct. The rotary machine includes a compressor section and a first turbine section. Each section of the rotary machine includes an inlet, an outlet, a duct extending between the inlet and the outlet, and an impeller in the duct. The rotary machine also includes a tie rod mechanically connecting the compressor impeller and the first turbine impeller. The first bypass duct is between the compressor section and the first turbine inlet. The check valve opens the first bypass duct when an air pressure in the compressor inlet is higher than an air pressure in the first turbine inlet.
