  • Patent number: 10569887
    Abstract: A system and method onboard an aircraft includes a ram air temperature sensor, a bleed air temperature sensor, a valve, and a controller. The ram air temperature sensor is positioned to sense a ram air temperature of a ram air flow. The bleed air temperature sensor is positioned to sense a bleed air temperature of a bleed air flow, wherein the bleed air flow is cooled by a heat exchanger using the ram air flow. The valve is configured to control the bleed air flow upstream of the heat exchanger. The controller is configured to determine a bleed air threshold based on the ram air temperature, and control the valve to reduce the bleed air flow in response to the bleed air temperature reaching the bleed air threshold.

  • Publication number: 20190291876
    Abstract: An aircraft includes one or more engines configured to generate high-pressure bleed air and low-pressure bleed air. An aircraft environmental control system (ECS) is in fluid communication with one or more of the engines to receive the high-pressure bleed air and the low-pressure bleed air. The ECS calculates a synthesized low-pressure value associated with the low-pressure bleed air while still providing bleed air using the high pressure bleed air. The ECS further switches from the high pressure bleed air to the low-bleed pressure air through the ECS while blocking flow of the high-pressure bleed air through the ECS based on the synthesized low-pressure value.

  • Publication number: 20190291872
    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.

  • Publication number: 20190293204
    Abstract: An aircraft environmental control system (ECS) includes a first valve that is adjustable between a plurality of first positions to open or shut-off a bleed air flow that flows from an inlet of the first valve to an outlet of the first valve. A second valve includes an inlet in fluid communication with the first valve outlet, and is adjustable between a plurality of second positions to throttle the bleed air that flows from the inlet of the second valve to an outlet of the second valve. A valve position sensor outputs a position signal indicating a measured position among the plurality of second positions. A controller is in signal communication with the valve position sensor. The controller is configured to determine a primary effective area of the second valve based on the measured position, and to diagnose operation of the first valve based on the primary effective area.
