  • Patent number: 10544705
    Abstract: A system and method of using the system includes an open-loop path and a closed-loop path. The open-loop path is configured to extract bleed air from a compressor section of a gas turbine engine through a bleed air port and discharge bleed air to an ambient environment. The closed-loop path is configured to circulate a working fluid through a heat exchanger, a turbine, and a condenser with a pump. The heat exchanger is fluidly coupled to the bleed air port and configured to extract heat from the bleed air to boil the working fluid for driving the turbine and a component rotationally coupled to the turbine.

  • Publication number: 20200010203
    Abstract: An environmental control system (ECS) for an aircraft includes at least one cooling turbine, and a turbine bypass valve disposed fluidly upstream of the at least one cooling turbine. The turbine bypass valve is configured to direct a first portion of an ECS output airflow to a first air load at a first pressure via a first outlet passage, and direct a second portion of the ECS output airflow across a cooling turbine of the at least one cooling turbine and to a second air load at a second pressure lower than the first pressure for cooling thereof.

  • Publication number: 20200002007
    Abstract: An environmental control system of an aircraft includes at least one heat exchanger and a compression device arranged in fluid communication with the at least one heat exchanger. The compression device includes a plurality of components including a first component and a second component coupled by a shaft. A first bleed port is arranged in fluid communication with the first component and a second bleed port, distinct from the first bleed port, is arranged in fluid communication with the second component.

  • Patent number: 7533313
    Abstract: A method for converting data includes generating a first data vector of data measurements related to processing of at least one workpiece. Each element of the first data vector is associated with at least one of a plurality of positions on the workpiece. A cumulative distribution of the elements in the first data vector is generated. An outlier region of the data measurements is identified based on the cumulative distribution. A binary outlier data vector is generated from the first data vector by assigning a first binary value to the data elements in the first data vector in the outlier region and assigning a second binary value to the remaining data elements in the first data vector.
