Air intake for large-size nacelle with enhanced transportability

An air intake to the fan of a turbofan engine, which intake can be fixed to the front of an engine casing enclosing said fan, and comprises an annular internal wall (6), an annular external cowl (5) spaced radially away from the internal wall (6), an annular rear partition (2) connecting the rear ends of the internal wall (6) and of the external cowl (5), an annular front partition (3) connecting the front ends of the internal wall (6) and of the external cowl (5), an annular rear flange (1) situated in the continuation of the internal wall (6) and intended for securing said air intake to the front of the engine casing and an annular front lip (4) which, with the front partition (3) forms an annular de-icing chamber (3, 4) which can be connected to a de-icing system, said air intake being made in at least two separable parts,

• characterized in that the plane (P1) of separation of the two parts passes on the outside of the de-icing chamber (10), of the internal wall (6) and of the rear flange (1) and cuts a cap (9) from the external cowl (5) and a crescent (8) with a straight edge (12) from the rear partition (2) so as to form a structural main part which wholly comprises the rear flange (1), the internal wall (6) and the de-icing chamber (10) and comprises most of the external cowl (5) except for the cap (9), and most of the rear partition (2) except for the crescent (8), means being provided for fixing the cap (9) and the crescent (8) to said main part later.
