摘要: An electric machine control system includes a control unit (102), wherein the control unit includes inputs for a POR voltage feedback (106), an electric machine current feedback (108), a PMG feedback (110), and an input speed feedback (112). A protection unit (104) includes inputs for: the POR voltage feedback, the electric machine current feedback, the PMG feedback, and the input speed feedback. At least one trip connection (134) connects between the control unit and the protection unit. A method of generator control includes receiving an input speed feedback, a generator line contactor (GLC) auxiliary feedback, a generator control switch (GCS) feedback, and the weight on wheels feedback in a control unit. The method includes determining within the control unit if voltage regulation and/or frequency regulation should be enabled independent from a protection unit operatively connected to the control unit.

摘要: A microprocessor-PLD hybrid architecture includes an IPC microprocessor (102) and a PLD (150) in signal communication with the IPC microprocessor (102) via an IPC interface (104). The IPC microprocessor (102) outputs a data read command to initiate a data read operation or a data write command. The PLD includes a plurality of PLD modules (154a-154n) that store data and a bus controller (152). The bus controller (152) communicates with the plurality of PLD modules (154a-154n) via a plurality of PLD interfaces (170) and is configured to sequentially execute a set of bus controller instructions (166). The bus controller (152) reads data from a target PLD module from among the plurality of PLD modules (154a-154n) in response to receiving the data read command, and transfers the data to the IPC microprocessor (102). The bus controller (152) receives data from the IPC microprocessor (102) and stores the data in a target PLD module from among the plurality of PLD modules (154a-154n) in response to receiving the data write command.

摘要: A valve includes a housing (102). A stroking valve (104) is operatively connected to the housing for valve stroking movement relative to the housing in a direction of a longitudinal axis of the housing. The stroking valve has an open position for flow through the housing and a closed position for blocking flow through the housing. The stroking valve is configured to make sealing contact with a second face seal (114) between a seal block (108) and the stroking valve after a first portion of a stroke from the open position to the closed position prior to making sealing contact with a first face seal (112) between the stroking valve and the housing.

摘要: An environmental control system for a vehicle includes a source (24) of a first medium, a cabin air compressing device (30a, 30b) including a compressor (32) having a compressor inlet (36) and a compressor outlet (59), and a conduit (37) fluidly coupling the source of the first medium to the compressor inlet. The first medium provided to the compressor inlet is output at the compressor outlet as a compressed first medium. An environmental control system pack is located downstream from and is fluidly coupled to the compressor outlet. The environmental control system pack includes a ram air circuit (42) having at least one ram air heat exchanger. Another conduit for providing a second medium to the compressor fluidly couples an outlet of the at least one ram air heat exchanger and the compressor inlet.

摘要: A heat exchanger includes a first header (20), a second header (22), and a core (24). The first header includes a fluid inlet (28). The second header is positioned downstream of the first header with respect to a first flow path of a first fluid. The second header includes a fluid outlet (30). The core extends from the first header to the second header. The core includes a plurality of tubes (32). The heat exchanger also includes a first region (60) which is at a higher temperature than regions adjacent to the first region. The first region is made of a first mixture of materials in a first ratio. The first mixture of materials causes a coefficient of thermal expansion in the first region to be lower than coefficients of thermal expansion in the regions adjacent to the first region.
