Definitions
- the invention relates to the field of combustion chambers of aircraft turbomachines, of the constant volume combustion type.
- turbomachine in particular turbojet engines, turboprop engines, and turbomachines with unducted fans, also known by the Anglo-Saxon term "Open Rotor”.
- the combustion chamber of a conventional aircraft turbine engine operates according to a so-called Brayton cycle, that is to say a constant pressure combustion cycle. Nevertheless, to obtain specific consumption gains, it has been envisaged to replace the combustion chamber operating on a Brayton cycle with a combustion chamber operating on a Humphrey cycle, that is to say a combustion cycle with constant volume or "CVC".
- the document FR-2945.316 describes an exemplary embodiment of an HVAC combustion chamber.
- the chamber comprises at the inlet a compressed gas inlet valve composed of two rotary elements of substantially ovoidal section which are rotatably mounted along axes parallel to each other and perpendicular to the axis of the chamber, said elements being able to determine when they are disjointed an open position of the valve and when they are joined a position closing the valve.
- the chamber likewise has at its exit a similar exhaust valve capable of oscillating between an open position and a closed position.
- the positions of the valves are controlled in a synchronized manner to implement the three successive phases of the Humphrey cycle, namely admission / sweep - combustion - exhaust.
- the design of the intake and exhaust valves is perfectible, particularly in terms of robustness and sealing, the latter can be problematic especially during the high pressure observed during the phase of combustion, because of the perfectible sealing of the ovoid section elements.
- an HVAC combustion chamber comprising spherical valves comprising spherical rotors rotatably mounted about axes perpendicular to the axis of the chamber and combined with spherical shells of these rotors, said rotors and said shells having alignable channels and lumens with each other and with combustion chamber exit inlet channels for selectively determining the opening or closing of corresponding intake and exhaust valves.
- Each chamber has a spherical valve at each end thereof, and said valves are synchronized with each other to implement the three successive phases of the Humphrey cycle.
- the design of the intake and exhaust valves is greatly improved, particularly in terms of sealing, but nevertheless has many disadvantages.
- each chamber requires an intake valve and an exhaust valve which are its own, so that a turbomachine comprising several chambers comprises as many intake valves and exhaust valves as chambers .
- DE-10.347.588-A1 has also been proposed a turbomachine comprising a compressor and a turbine connected by a common shaft, and a single combustion chamber CVC which is arranged on the periphery of the turbomachine around the shaft and between the compressor and the turbine.
- the HVAC chamber is capable of admitting intake gases via an intake rotary valve and discharging the exhaust gases to the turbine via a rotary exhaust valve.
- the rotary intake and exhaust valves each consist of two concentric rings provided with vanes, the vanes of the two rings being spaced at the same angular spacing. The vanes of each ring thus delimit a plurality of passages which are each arranged between two consecutive vanes of the ring.
- the vanes of each inner ring are thus capable of closing or releasing the passage between two vanes of the corresponding outer ring, depending on whether the vanes of the inner ring seal the passages between the vanes of the outer ring, or that they are aligned with the vanes of the outer ring and thus release the passages between the vanes of the outer ring.
- the blades of each inner ring aerodynamically extend those of the outer ring in a position of alignment of the blades corresponding to the full opening of the rotary valve.
- the sealing proposed by the rotary valves is imperfect because, in the closed position of the valve, the vanes of each inner ring can not cover angularly those of the corresponding outer ring at the risk of not prolong that imperfectly the blades of the outer ring in the alignment position of the blades corresponding to the open position of the valve, and thus constitute an obstacle to the flow of gases.
- the seal at the junction of the edges of the vanes of the inner ring and the edges of the vanes of the inner ring is therefore actually performed only at the edge of said blades, along an extremely thin sealing line, and is therefore therefore precarious.
- the invention therefore aims to overcome the disadvantages mentioned above, relating to the achievements of the prior art.
