Abstract
A turbine engine compressor, including a first housing for supporting injectors, a second housing arranged around the first housing while forming with the first housing an annular space therewith, and a plurality of air injectors each mounted in recesses. Each air injector includes at least one inner air injection channel which leads, on one side, into an outflow jet of the gas stream and, on the other side, into the space formed between the recesses, and, at an upstream end, an upstream rim having an inner surface radially bearing against an upstream rim of the corresponding recess of the first housing and an outer surface radially bearing against an inner surface of the second housing. A mechanism clamping the upstream rim of the air injectors between the housings enables the air injectors to be held in position in the recesses of the first housing.
