Kathrine J. Clarke has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • ECS with 2-stage water separation
    Patent number: 6381969
    Abstract: A two spool environmental control system includes a low pressure spool subsystem comprising a low pressure turbine and a condenser downstream of the low pressure turbine. A high pressure spool subsystem is in air flow communication with the low pressure spool subsystem and includes the condenser, a first water extractor in air communication with the condenser, a high pressure turbine downstream of the condenser, a second water extractor in air flow communication with the condenser, and a reheater downstream of the high pressure turbine.
    Type: Grant
    Filed: December 17, 1999
    Date of Patent: May 7, 2002
    Assignee: Honeywell International Inc.
    Inventors: George Afeiche, Kathrine J. Clarke, Roger Murry, Michel A. Jonqueres
  • Two spool environmental control system
    Patent number: 5887445
    Abstract: A two spool environmental control system includes a low pressure spool subsystem having a low pressure turbine. A high pressure spool subsystem is in air flow communication with the low pressure spool subsystem, while the high pressure spool subsystem is capable of conditioning compressed air prior to the low pressure spool subsystem conditioning the compressed air. The high pressure spool subsystem includes a high pressure turbine which is mechanically operable independently of the low pressure turbine.

  • Integrated power and cooling environmental control system
    Patent number: 5442905
    Abstract: An environmental control system has an air cycle machine that includes a compressor, a cooling turbine, a motor/generator, and a power turbine all mounted on a single shaft. The power turbine receives bleed air from the aircraft's engine and has a variable geometry inlet nozzle that adjusts the air flow rate therethrough without significant throttling. Downstream of the nozzle the power turbine extracts the expansion energy from the bleed air while cooling it. This is used to drive the other components of the air cycle machine, and in particular the motor/generator which generates electricity.
