Abstract: The invention relates to a combustion chamber module for an aircraft turbine engine, comprising a combustion chamber defined by an internal annular wall and an external annular wall provided with air intake openings, the module further comprising an internal housing and an external housing. According to the invention, at least one of the internal and external housings has, on the surface thereof facing the combustion chamber, a marking system comprising a plurality of different marks angularly spaced apart from each other, each mark being produced facing one of the air intake openings in order to be visible from inside the combustion chamber and each indicating the angular position of a zone of the combustion chamber comprising the air intake opening.

Abstract: An assembly includes an injection system and an injector for an aircraft turbomachine combustion chamber. The system includes an aerodynamic bowl including a first end widening toward the downstream end and centered on a central axis of the injection system, this also including a central body along which a film of fuel is intended to flow in the downstream direction. The central body includes a second end widening toward the downstream end, the first and second widening ends between them delimiting an air through duct and the system includes motion inducing a device allowing a relative movement between the first widening end which is stationary and the second widening end, along the central axis of the injection system, by moving the central body relative to the injector.
