Patent number: 10634065Abstract: An engine bleed air system having one or more taps in the compressor section of an aircraft engine, for example a low pressure tap and a high pressure tap. The low pressure tap is fluidly connected to the compressor of a turbo-compressor and the high pressure tap is fluidly connected to the turbine of the turbo-compressor. A bypass line connects the high pressure air to the outlet of the compressor, with a heat exchanger used to remove excess heat from the bypass line. An additional heat exchanger is used to remove any excess heat from the compressed air, dumping the heat to a fan stream or to the expanded air exiting the turbine. The system is controlled to minimize the amount of high pressure air extracted from the engine.Type: GrantFiled: September 30, 2014Date of Patent: April 28, 2020Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Louis J. Bruno, Gregory L. DeFrancesco, Thomas M. Zywiak, Diane G. Drew, Harold W. Hipsky, Daniel L. Hughes

Patent number: 9957051Abstract: An environmental control system (ECS) pack is provided including a primary heat exchanger, a secondary heat exchanger, and an air cycle machine. The air cycle machine includes a compressor and a turbine. The compressor is fluidly coupled to an outlet of the primary heat exchanger and to an inlet of the secondary heat exchanger. The outlet of the secondary heat exchanger is fluidly coupled to the turbine. A first conduit connects the outlet of the primary heat exchanger and the inlet of the secondary heat exchanger. The first conduit includes a first valve. A second conduit connects the outlet of the secondary heat exchanger to an air load. The second conduit includes a second valve.Type: GrantFiled: November 25, 2013Date of Patent: May 1, 2018Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Louis J Bruno, Thomas M. Zywiak, Diane G.

Patent number: 5704218Abstract: An integrated environmental control system is disclosed for providing conditioned supply air to loads such as a passenger cabin of an aircraft. The system comprises at least two shafts, each shaft having a fan, compressor, and turbine mechanically secured to the shaft; common heat transfer components including primary and secondary heat exchangers, a reheater, and a condenser with a water collector; lines that deliver the supply air separately through the compressors and turbines of each shaft and deliver the supply air in common through the common heat transfer components to the load; and shutoff valves secured in fluid communication with each turbine.Type: GrantFiled: April 8, 1996Date of Patent: January 6, 1998Assignee: United Technologies CorporationInventors: Douglas L.

Patent number: 5511385Abstract: A dual-pack, aircraft environmental control system has each pack dedicated to providing a temperature-controlled air supply to a corresponding compartment, either the crew or passenger, of the aircraft. Each refrigeration pack is fed hot, compressed bleed air from an associated turbine engine on the aircraft. During normal operation, the pack associated with a particular compartment on the aircraft provides the air supply with independent temperature control to that compartment. However, during failure of one of the refrigeration packs and the resulting operation of the other pack, the environmental control system is able to provide independent temperature control of the air supplied to each compartment.Type: GrantFiled: December 23, 1994Date of Patent: April 30, 1996Assignee: United Technologies Corp.Inventors: Diane G.
