A pulse combustor system for reducing noise and/or vibration levels. The system includes a pulse combustor including a combustion chamber, an inlet pipe, an exhaust pipe, and a first fuel injector for injecting fuel into the combustion chamber. The pulse combustor has a fundamental oscillation mode and one or more additional oscillation modes. The system includes at least one pressure sensor for measuring a pressure inside the fuel combustor and/or a at least one fluid velocity sensor for measuring fluid velocity at the inlet pipe or at the exhaust pipe. A controller adjusts a rate of fuel supply to the pulse combustor if the measured pressure and/or the measured velocity is above a predetermined threshold value to reduce excitation of the one or more additional oscillation modes.

An object of the present invention is to provide a method and a system for implementing the method so as to alleviate the disadvantages of a reciprocating combustion engine and gas turbine when generating power. The invention is based on the idea of arranging a combustion chamber (10) outside a turbine (22) and providing compressed air from serially connected compressors to an air chamber in which the air is heated and then exhausted to the combustion chamber in order to carry out a combustion process supplemented with high pressure steam pulses.

A constant volume combustion chamber for a turbine engine, includes an intake port, an exhaust port, and a first rotary shutter facing the intake and exhaust ports and configured to rotate around an axis in a first direction of rotation, the first shutter including an aperture intended to cooperate alternately with the intake and exhaust ports during the rotation of the first shutter. The chamber further includes at least one second rotary shutter facing the intake and exhaust ports and configured to rotate around the axis in a second direction of rotation opposite to the first direction, the second shutter including an aperture intended to cooperate alternately with the intake and exhaust ports during the rotation of the second shutter, the first and second shutters being synchronized and configured so that their respective apertures intersect alternately when both are facing the intake and when both are facing exhaust ports.
