Patent number: 11401889Abstract: A method of managing a gas turbine engine includes the steps of detecting an airspeed and detecting a fan speed. A parameter relationship is referenced related to a desired variable area fan nozzle position based upon at least airspeed and fan speed. The detected airspeed and detected fan speed is compared to the parameter relationship to determine a target variable area fan nozzle position. An actual variable area fan nozzle position is adjusted in response to the determination of the target area fan nozzle position and at least one threshold.Type: GrantFiled: September 30, 2020Date of Patent: August 2, 2022Assignee: RAYTHEON TECHNOLOGIES CORPORATIONInventors: Geoffrey T. Blackwell, William J. McVey, William G. Tempelman

Patent number: 10578053Abstract: A method of managing a gas turbine engine variable area fan nozzle includes the steps of operating a variable area fan nozzle according to a first operating schedule. An icing condition input is evaluated to determine the likelihood of ice presence. The first operating schedule is altered to provide a variable area fan nozzle position if ice is likely present or actually present to provide an icing operating schedule different than the first operating schedule. The first operating schedule corresponds to the flaps at least partially open at air speeds below a first airspeed. The altering step includes closing the flaps below the first airspeed as part of the icing operating schedule. The variable area fan nozzle position is adjusted according to the icing operating schedule. A fan is arranged in a fan nacelle that includes a flap configured to be movable between first and second positions. An actuator is operatively coupled to the flap.Type: GrantFiled: January 27, 2017Date of Patent: March 3, 2020Assignee: United Technologies CorporationInventors: Geoffrey T. Blackwell, William G. Tempelman, William J. McVey

Patent number: 10267326Abstract: An example variable vane scheduling method includes adjusting variable vanes from a position based on a first schedule to a position based on a different, second schedule in response to a control feature. An example method of controlling flow through a compressor of a turbomachine includes moving variable vanes to positions that allow more flow into the compressor in response to bleed air being communicated away from the compressor.Type: GrantFiled: November 6, 2012Date of Patent: April 23, 2019Assignee: United Technologies CorporationInventors: Matthew D. Teicholz, Paul H. Spiesman, Kerri A. Wojcik, John R. Gendron, Glenn D. Bartkowski, Sean D J Blake, William G. Tempelman
