Patent number: 11180259Abstract: 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.Type: GrantFiled: March 21, 2018Date of Patent: November 23, 2021Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Jeffry K. Kamenetz, Erin G. Kline, Jeffrey Ernst, Bruce R. Schroder, Kevin R. DeRoy, Vince Vessella, Darragh McGrath, Adam Fagnani, Michel Labrecque

Patent number: 11008948Abstract: A system includes a venturi duct, a first delta P sensor, a second delta P sensor, and an ECS controller. The venturi duct is configured to receive a first bleed air flow or a second bleed air flow. The first and second delta P sensors are configured to sense a first and second pressure difference between a first point and a second point of the venturi duct. The first and second delta P sensors are configured to sense pressure difference over different pressure ranges. The ECS controller is configured determine a flow rate of an ECS air flow based upon the first pressure and/or second sensed pressure differences.Type: GrantFiled: September 13, 2018Date of Patent: May 18, 2021Assignee: Hamilton Sundstrand CorporationInventors: Robert M.

Patent number: 10926883Abstract: 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.Type: GrantFiled: March 21, 2018Date of Patent: February 23, 2021Assignee: HAMILTON SUNSTRAND CORPORATIONInventors: Jeffry K.

Patent number: 10711916Abstract: 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.Type: GrantFiled: March 21, 2018Date of Patent: July 14, 2020Assignee: HAMILTON SUNSTRAND CORPORATIONInventors: Jeffry K.
