摘要： In a fuel control system (10) for a gas turbine engine (1) having a gas generator (4) and a turbine (6) driven by the gas generator (4): a main fuel regulator (12) determines a demand (W f dem) of fuel flow (W f ) to be introduced in the gas turbine engine (1), based on an input request (PLA); and a first limiter stage (14), operatively coupled to the main fuel regulator (12), causes an adjustment of the fuel flow (W f ) based on engine safety operating limits. The first limiter stage (14) is provided with a Ngdot limiter (20) to cause an adjustment of the fuel flow (W f ) when the gas generator speed rate of change (Ngdot) is determined to overcome acceleration/deceleration scheduled safety limits; the Ngdot limiter (20) implements a predictor (23), to perform a prediction ( W f dot ) of the fuel flow rate of change (W f dot), or fuel flow (W f ), allowing the gas generator speed rate of change (Ngdot) to track a scheduled reference value (Ngdot ref ).

摘要： A power conversion system (10) of the modular type for an electromagnetic device (1) is described, provided with a plurality of modules (2) having a reversible operation, operable either as a generator or as an electric motor. The power conversion system has a modular structure, with a plurality of converters (12), each connected to an assignable number of modules (2), and is provided with a control module (20; 21), to reconfigure the system, even during its operation, by defining an assignment between converters (12) and a respective number of modules (2), and/or the operation as a generator or as an electric motor of the same modules (2).

摘要： The present disclosure is directed to a system and a method for determining an aircraft (10) minimum low pitch setting for a propeller assembly (30) and minimum gas generator idle speed for a gas generator (100), in which the propeller assembly (30) and the gas generator (100) together comprise a gas turbine engine. The method comprises determining, via one or more controllers (210), an operating condition of the aircraft (10) based at least on a weight on wheels (WoW) signal and a throttle lever (22) position. The WoW signal produces a first mode or a second mode different from the first mode, and the throttle lever position defines at least a takeoff position and an idle power position.

摘要： A method (600) for testing control logic for a propeller driven by a gas turbine engine of an aircraft includes overriding a signal indicating the aircraft is operating in a ground mode (602); testing minimum pitch protection logic when the signal is overridden (604); determining the gas turbine engine is operating at a ground fine setting (606); restoring the signal to an original state in which the signal indicates the aircraft is operating in the ground mode (608); modifying propeller overspeed protection logic (610); determining the propeller is operating at a low pitch (612) and at an overspeed (614) condition; and testing the propeller overspeed protection logic (616). In addition, the method also determines that the propeller is operating at a low pitch condition when the gas turbine engine is operating at the ground fine setting.
