| 摘要 |
The invention relates to an air supply plenum (12) for an engine, the plenum being disposed upstream of an air intake (2) of said engine, the air intake being provided in a casing (3) of said engine. The air supply plenum (12) comprises a first lateral wall (121) and a second lateral wall (122) which together form a conduit in which an air flow (7) flows as the engine functions. The invention is characterized in that each lateral wall (121, 122) comprises a step (8) which forms a transverse recess relative to the direction of the air flow (7) in the air supply plenum (12), such that an aerodynamic separation (6) occurs in the step (8) when the engine is operating. |
