Abstract
In a turbofan engine, the mechanical connection between the pod (12) and the fan stator case (10) is limited to a centering system (22) in the immediate vicinity of the arms (20) by which the fan stator case is mounted on the central portion (16) of the engine. The aerodynamic and inertia loads applied to the pod (12), particularly on take-off and landing, consequently only lead to an acceptable deformation of the fan stator case (10). Thus, the gap between said case and the fan (18) can be kept to a very small value, which ensures maximum engine efficiency. Moreover, the centering system (22) prevents an excessive radial displacement (J') between the front of the fan stator case (10) and the adjacent portion of the pod.
