    Abstract: An environmental control system includes an environmental control system pack having a trim outlet and a primary outlet. A trim medium is output from the trim outlet and a first medium is output from the primary outlet. An inlet of a mixing manifold is connected to the primary outlet of the at least one environmental control system pack. A trim heat exchanger is connected to the trim outlet and the at least one inlet of the environmental control system pack. Within the trim heat exchanger, the trim medium is arranged in a heat exchange relationship with a second medium. From the trim heat exchanger, the second medium is provided to an inlet of the least one environmental control system pack and the trim medium is mixed with a flow output from an outlet of the mixing manifold.

    Abstract: A method for providing inert gas to a protected space. The method includes: providing air having a pressure greater than or equal to 2 atmospheres absolute pressure to a chemical inert gas generator; producing an inert gas in the chemical inert gas generator; providing the inert gas to a condenser at an elevated pressure; reducing the water content of the inert gas in the condenser; and providing the dried inert gas to a protected space.

    Abstract: A compressing device for use in an environmental control system includes at least one turbine configured to provide energy by expanding one or more mediums. The one or more mediums provided at an outlet of the at least one turbine form a heat sink within the environmental control system. A compressor is configured to receive energy from the one or more mediums expanded across the at least one turbine. During a first mode of the compressing device, energy derived from a first medium and a second medium of the one or more mediums is used to compress a second medium at the compressor. During a second mode of the compressing device, energy derived from the first medium, the second medium, and a third medium of the one or more mediums is used to compress the second medium at the compressor.

    Abstract: A motor drive system includes a MUX circuit, a DC voltage scaling circuit, a fault detection circuit, an ADC, and an FPGA. The MUX circuit selectively establishes a MUX input signal path and a MUX output signal path. The DC voltage scaling circuit measures a DC link voltage. The fault detection circuit receives the output DC link voltage and outputs one of a normal operation signal or a fault signal in response to comparing the DC link voltage to one or both of a U/V reference voltage and an O/V reference voltage. The ADC converts one or more input analog voltages into respective corresponding output digital voltages. The FPGA is in signal communication with the ADC output (ADCOUT) and the MUX circuit, and is configured to control the motor drive system based on a comparison between one or more of the output digital voltages.

    Abstract: An environmental control system of a vehicle includes a first inlet configured to receive a flow of a first medium, a second inlet configured to receive a flow of a second medium, and a thermodynamic device including a compressor and at least one turbine operably coupled by a shaft. The compressor and the at least one turbine are fluidly coupled to the first inlet. The compressor and the at least one turbine are arranged in parallel relative to the flow of the first medium such that a first portion of the first medium is receivable at the compressor and a second portion of the first medium is receivable at the at least one turbine.
