Embodiment Construction

[0046] The particle trap according to the invention has the general reference numeral 2 .

[0047] like figure 2 As can be seen in , the device 2 is designed to be positioned in the bypass region 17 of the combustion chamber 13, more precisely outside the wall 131 of the combustion chamber 13 and inside the outer casing 18 of the turbine.

[0048] However, the exact position of the device will be determined by calculation from the trajectories of the particles contained in the air flow circulating inside the bypass area 17 . This calculation also takes into account the corresponding shapes of the wall 131 and the portion of the wall 180 of the outer casing 18 situated towards the rear end of the combustion chamber 13 .

[0049] Thereby, the trapping means will advantageously be positioned at a position which will allow the greatest amount of particles to be collected before the particles reach the holes 130 in the wall of the combustion chamber.

[0050] will now refer to ...

Abstract

The invention relates to a particle-trapping device (2) for a turbo machine, said particles being contained in an air stream flowing inside a turbo machine, in particular the air stream flowing in thebypass region (17) of the combustion chamber (13) of said turbo machine. The device is characterized in that it comprises: at least two particle deflectors (3, 3a, 3b, 3c), a member (5) for collecting and storing the particles deflected by said deflector, and means (6) for attaching said trapping device (2) to a part of the turbo machine.

Description

technical field [0001] The invention relates to the field of turbines equipped in particular aircraft or helicopters. [0002] The invention relates more precisely to a particle trap for a turbomachine, especially sand or dust particles contained in the air flow circulating inside said turbomachine. The trapping device is more particularly designed to be arranged in the bypass region of the combustion chamber of the turbomachine. [0003] The invention also relates to a turbine equipped with such a capture device. Background technique [0004] as attached figure 1 As can be seen in the schematic diagram of , the turbine 1 generally comprises, from upstream to downstream in the direction of air flow, an air inlet 11, one or more compressor stages 12 (such as a single compressor stage in this figure), an annular combustor 13, one or more turbine stages (such as a high-pressure turbine 14 and a low-pressure turbine 15 ) and the final exhaust nozzle 16 . [0005] Hereinafter...
