- the present invention relates in a in the field of combustion chambers turbomachine rings, and more particularly to that of means for thermally protecting these combustion chambers.
- a combustion chamber annular turbomachine comprises an axial wall external and an inner axial wall, these walls being arranged coaxially and interconnected by through a chamber floor.
- the combustion chamber is provided with injection ports each intended for receive a fuel injector to allow combustion reactions inside this chamber of combustion. It is further noted that these injectors can also be used to introduce least part of the air intended for combustion, this occurring in a primary zone of the combustion chamber, located upstream of a zone secondary called dilution zone.
- the chamber floor is provided with a plurality of passages allowing to pass cooling air inside the chamber of combustion. It is stated that these passages may be practiced on deflectors equipping the bottom of chamber, these deflectors, also called cups or heat shields, being provided for the purpose of generate protection against thermal radiation.
- passages are usually designed from to allow the initiation of an air film of cooling along the warm inner surface of the outer axial wall, as well as the initiation of a cooling air film along the surface hot interior of the inner axial wall.
- the air films of Initiated cooling at the bottom of chamber are relatively circumferential homogeneity mediocre, especially when this chamber background is equipped with baffles.
- the characteristics of these films are highly likely to evolve course of time, mainly because of the progressive deformation of the constituent elements of bedroom background.
- the object of the invention is therefore to propose a turbomachine annular combustion chamber, at least partially overcoming the disadvantages mentioned above relating to the achievements of art prior.
- the purpose of the invention is to present an annular combustion chamber of turbomachine, whose design allows particular to get more axial wall temperatures homogeneous than those encountered in the realizations of the prior art.
