  • Method and system for glow plug operation
    Patent number: 11739693
    Abstract: There are described methods and systems for operating a glow plug. The method comprises monitoring a glow plug current; applying a nominal voltage VN to the glow plug when the glow plug current is between an upper threshold I1 and a lower threshold I2<I1; applying a voltage VH>VN to the glow plug when the glow plug current exceeds the upper threshold I1; and applying substantially no voltage to the glow plug when the glow plug current falls below the lower threshold I2.
    Type: Grant
    Filed: November 18, 2020
    Date of Patent: August 29, 2023
    Assignee: PRATT & WHITNEY CANADA CORP.

  • Methods and systems for operating a gas turbine engine
    Patent number: 11326468
    Abstract: Methods and systems for operating a gas turbine engine are provided. A health parameter for the gas turbine engine is monitored at a health evaluation device via a first instrument, the health evaluation device being communicatively coupled to a communication link established between a controller, associated with the gas turbine engine, and a second instrument which provides the controller with an operation parameter indicative of an operating condition of the gas turbine engine. The health parameter is compared to a predetermined threshold. When the health parameter is beyond the predetermined threshold, a signal is injected into the communication link to produce a predetermined value for the operation parameter to elicit a health response from the controller associated with the predetermined value.
