    摘要: A system is disclosed for actively controlling combustion in a gas turbine engine (10), which includes a fuel injector (110) for issuing fuel into a combustion chamber of the gas turbine engine. The fuel injector has a dynamic pressure sensor (130) for measuring acoustic pressure within the combustion chamber and a flame sensor (140) for observing flame characteristics within the combustion chamber. The system further includes a high speed valve assembly (112) for controlling flow of fuel to the injector and an electronic controller associated with the fuel injector for commanding the valve assembly to deliver fuel to the fuel injector at a commanded flow rate, based upon input from the sensors in the fuel injector.

    摘要: A method of controlling combustion stability in a turbine engine having combustion stability control capability includes the steps of providing at least one pair of pulsating valves, mutually arranged in parallel with respect to fuel flow provided to a combustor of the turbine engine, detecting an amplitude and frequency of a pressure wave of at least one periodic combustion instability, selecting an amplitude, frequency and first phase shift, with respect to the pressure wave, of resultant fuel pulsations to reduce the amplitude of the pressure wave, translating the selected amplitude into a second, relative phase shift between each pulsating valve of at least one pair of pulsating valves, and commanding each pulsating valve of at least one pair of pulsating valves to operate at the selected frequency and a relative second phase shift with respect to one another, to yield a resultant fuel pulsation at the selected amplitude, frequency and first phase shift, with respect to the detected pressure wave of combustion instability.
