A turbine engine system utilizes one or more augmented combustion modules to produce an exhaust that is fed into the turbine portion of the engine and wherein power is produced by the augmented combustion module for use to drive the main shaft and/or for auxiliary purposes. An augmented combustion module is configured between the compressor and the turbine of the engine and receives compressed air from the compressor and ignites an air/fuel-mixture to turn a shaft that can be used to produce power. The shaft may be coupled with an electrical power generator, a pump, a hydraulic or pneumatic power generator and/or power conversion or transmission devices and/or coupled with the main shaft of the turbine engine. The power from a power generator may be stored in a battery, hydraulic accumulator or pneumatic accumulator and may be used to power auxiliary electrical, hydraulic or pneumatic devices.

A constant-volume combustion system for a turbomachine includes a plurality of combustion chambers distributed in an annular manner about an axis defining an axial direction, each combustion chamber including an intake port and an exhaust port; a selective closure member rotationally movable about the axis with respect to the combustion chambers, the selective closure member including a ferrule facing the intake and exhaust ports of the combustion chambers, the ferrule containing at least one intake aperture intended to cooperate with the exhaust port of each chamber and at least one exhaust aperture intended to cooperate with the exhaust port of each chamber. Each intake aperture and each exhaust aperture are segmented by at least one segment extending in each aperture in the axial direction.
