  • Method, system, and apparatus for reducing a turbine clearance
    Patent number: 9758252
    Abstract: A method for reducing a turbine clearance gap between a plurality of rotor blades of a turbine engine and a shroud of the turbine engine is provided. The method includes determining that an airplane is in a first flight condition, and adjusting the turbine clearance gap to a first clearance gap distance associated with the first flight condition. The method also includes determining a demand for a second flight condition, and adjusting an engine responsiveness to a first engine responsiveness for a first predetermined change in a power parameter of the engine. The method further includes reducing the engine responsiveness from the first engine responsiveness level to a second engine responsiveness level for a second predetermined change in the power parameter of the engine, and closing a clearance control valve associated with the shroud during the second predetermined change in the power parameter of the engine.

  • Methods for derated thrust visualization
    Patent number: 8977413
    Abstract: Methods of illustrating one or more derated takeoffs of an aircraft on a runway where such illustrations are on a flight display in a cockpit of the aircraft and are based on various information and may allow pilots to make more accurate decisions related to derated takeoffs and full thrust takeoffs of the aircraft.

  • METHOD, SYSTEM, AND APPARATUS FOR REDUCING A TURBINE CLEARANCE
    Publication number: 20140058644
    Abstract: A method for reducing a turbine clearance between a plurality of rotor blades of a turbine engine and a shroud of the turbine engine is provided. Said method includes determining, with a flight operation controller, that an airplane is in a first flight condition, wherein the first flight condition is associated with a first turbine clearance and a first engine responsiveness level, determining, with the flight operation controller, that the airplane is in a second flight condition, adjusting an engine responsiveness level from the first engine responsiveness level to a second engine responsiveness level based on determining the airplane is in the second flight condition, and adjusting the turbine clearance from the first turbine clearance to a second turbine clearance based on the engine responsiveness level.
