  • Patent number: 10669031
    Abstract: A method for supplying pressurized air to an aircraft includes that bleed air is bled from a portion of a turbomachine of the aircraft and a thrust output of the turbomachine is increased to increase a pressure of the bleed air in a predetermined environmental condition. The method also includes that modes of an environmental control system (ECS) are switched from a first operating mode configured to receive bleed air from each engine of the aircraft in a first environmental condition to a second operating mode configured to receive bleed air from at least one engine of the aircraft in a second environmental condition. The method further includes that engine thrust is increased in at least one engine and engine thrust is reduced from at least the other engine to maintain a constant total thrust when the ECS is in the second operating mode.

  • Patent number: 10634065
    Abstract: 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.
