Patent
CA 2168631
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 inoperative state diameter of that part of the sleeve which is fitted 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 circumfer- ential displacement between the two ends thereof. An inflatable member (46) can be placed about that part of the sleeve which is fitted to the frame.
