Abstract
In a turbofan engine, particularly of the type in which the front end of the fan frame (26) is separate from the air inlet (24), the seal between the said two structures is provided by an elastic sleeve (32) fixed to the air inlet and fitted onto the front part of the fan frame. The diameter of the part of the sleeve before it is mounted onto the frame (26) is smaller than the external diameter of the front part of the latter. The sleeve (32) has an internal fitting preventing any relative circumferential displacement between the two ends thereof. An inflatable member (46) can be placed about that part of the sleeve which is fitted into the frame.
