Device for tapping off air in a turbojet

摘要

The invention relates to a device for tapping off air in a turbojet, the latter comprising, in succession along its longitudinal axis (10), a compressor and a double-headed annular combustion chamber between which there is a diffuser (2) including an annular flow splitter (3) placed between the internal casing (2i) and external casing (2e) of the diffuser and fixed to the outer casing by a set of hollow radial structural arms (4), the splitter thus creating, from the air flow (F) originating from the compressor, an external air flow (Fe) intended for the idling head and an internal air flow (Fi) intended for the take-off head. Air is drawn off via the internal volume of the arms (4) and orifices (30) and (20), exclusively from the internal flow (Fi). <IMAGE>
