20180010517 · 2018-01-11 · ·

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).

Constant volume combustion system

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.

Pulse Detonation Wave Generator
20230147062 · 2023-05-11 ·

A device and assembly for reliably generating supersonic detonation waves in a fuel and air or fuel and oxygen mixture. The device uses a hemispherical detonation chamber into which reactants, consisting of a fuel and air or oxygen mixture are injected and ignited by a laser to initiate a detonation wave. The wave is reflected by the hemispherical geometry of the detonation chamber and exits the device through a fast-acting valve. The detonation chamber is then purged and the cycle is repeated many times per second. The device can be used for various applications which include but are not limited to a stand-alone intermittent combustion engine, a pre-detonator for an intermittent combustion engine, a projectile launcher, a cleaning device, acoustical energy generation, pressure energy generation, various manufacturing processes and electric power generation. The device may use liquid, gaseous, or solid fuels, depending on the application.

Standing detonation wave engine

A detonation engine can detonate a mixture of fuel and oxidizer within a cylindrical detonation region to produce work. The detonation engine can have a first and a second inlet having ends fluidly connected from tanks to the detonation engine. The first and second inlets can be aligned along a common axis. The inlets can be connected to nozzles and a separator can be positioned between the nozzles and along the common axis.
