Abstract: An environmental control system of a vehicle includes a first inlet for receiving a first medium, a second inlet for receiving a second medium, and an outlet for delivering a conditioned medium to a load. A first compression device is configured to receive and compress the first medium and a second compression device is configured to receive and compress the second medium. The first medium and the second medium are mixed together at a mixing point such that a mixture of the first medium and the second medium is the conditioned medium provided at the outlet.

Abstract: An aircraft includes a first engine that generates first bleed air flow and a second engine that generates second bleed air flow. The aircraft further includes an aircraft environmental control system (ECS) with a bleed manifold to collect the first bleed air flow and the second bleed air flow, and one or more air cycle machines to perform air conditioning consuming bleed air flow from the bleed manifold. The ECS balances the first bleed air flow and the second bleed air flow output from the first engine and second engine, respectively, based on a bleed manifold pressure of the bleed manifold.

Abstract: A valve control system includes a valve connected to regulate flow of a medium provided to an output and a sensor connected to monitor a feedback value associated with the medium. A controller modulates the valve based on a comparison of a reference value to the feedback value provided by the sensor. The controller detects saturation of the valve if the error between the monitored feedback value and reference value exceeds a threshold. In response to detected saturation, the controller reduces the reference value to a value less than the monitored feedback value.

Abstract: An environmental control system of an aircraft includes a ram air circuit including a ram air shell having a plurality of heat exchangers positioned therein, the plurality of heat exchangers including a first heat exchanger, a second heat exchanger, and a third heat exchanger. The ram air circuit is configured and arranged so that a first medium received at the first heat exchanger passes through the first heat exchanger and then through the third heat exchanger and so that a second medium received at the second heat exchanger passes through the second heat exchanger. A compressing device is arranged in fluid communication with the ram air circuit.

Abstract: A system and method includes a heat exchanger, a ram inlet actuator, and a controller. The ram inlet actuator is configured to control ram air flow from a ram air inlet to the heat exchanger, and the heat exchanger is configured to provide cooling for a bleed air flow. The controller is configured to determine a predicted ram flow based on a bleed air temperature drop across the heat exchanger, a flow rate of the bleed air flow, and a ram air temperature at the ram air inlet. The controller is configured to control the ram inlet actuator based on the predicted ram flow.

Abstract: A system for controlling bleed air flow in an aircraft is described herein. High-pressure compressor bleed air is regulated in a stepped manner with a bleed full open/full closed valve and a second, bleed half open/full open valve, or with a complex multi-step valve. This mitigates severe pressure transient conditions and results in a less drastic pressure differential across a downstream pressure or flow control valve before the bleed air is repurposed for other uses in the aircraft. The system allows for better downstream system stability across the aircraft operational envelope.

Abstract: An airflow control system includes a valve including a valve disk rotatable within a flow control duct and a valve actuator connected to the valve disk. The valve actuator is operable to adjust a position the valve disk. A pneumatic controller is configured to regulate a pressure within the flow control duct downstream of the valve disk by adjusting the position of the valve disk when the pressure within the flow control duct downstream of the valve disk exceeds a regulation pressure set point. A torque motor is fluidly connected to the valve actuator and a digital controller is operably coupled to the torque motor. The digital controller is configured to regulate the pressure within the flow control duct downstream of the valve disk independently from the pneumatic controller.
