Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a turbine engine combustion module (10), in particular for an aircraft turbine engine, designed to carry out constant-volume combustion, comprising: at least two combustion chambers (12A, 12B) arranged about an axis, each chamber (12A, 12B, 12C) comprising a compressed gas intake port (16) and a burnt gas exhaust port (18); and an ignition means that triggers combustion in the combustion chambers (12A, 12B, 12C). The module (10) comprises at least one duct (80) which establishes a communication between a first combustion chamber (12A) and at least one second combustion chamber (12B) in order to inject burnt gases from the first combustion chamber (12A) into the second combustion chamber (12B) so as to trigger combustion in the second combustion chamber (12B).

Abstract: A constant volume combustion system includes at least one combustion chamber having at least one admission port and an exhaust port. The system also includes at least one elastically deformable tongue made of ceramic matrix composite material forming an air admission valve, the tongue being present inside the chamber and being positioned facing the admission port, the tongue having a first end that is stationary relative to an inside wall of the chamber and a second end, opposite from the first end, the second end being free and movable relative to the inside wall.
