A part or an assembly of parts of a splitter stage of a turbofan, including a plurality of obstacles including at least one a blade and at least one arm, and a platform from which the obstacles extend, wherein the arm is defined by a skeleton angle having a trailing value on the trailing edge of between 3&#xb0; and 15&#xb0;.

Dimensioning of the skeleton angle of the trailing edge of the arms crossing the by-pass flow of a turbofan

The invention relates to an intermediate housing hub () comprising a discharge stream conduit () having a given length (L), and discharge fins () extending in the discharge stream conduit () and having a given chord length (L), the chord length (L) of at least one of the discharge fins () being at least equal to 50% of the length of conduit (L).

Intermediate housing hub comprising discharge flow guiding channels formed by the discharge fins

A disclosed propulsion unit includes a pylon having a blade presenting a chord Cx and a downstream arm having a structural arm. The pylon has a first distance D between a trailing edge of a fan blade and a leading edge of the fan blade, a second distance d between said trailing edge of the blade and a leading edge of the structural arm, and a third distance L between the trailing edge of the blade and a mark located at a maximum thickness of the downstream arm. The pylon is dimensioned according to: a first quotient between D and Cx between 2.2 and 2.6, a second quotient between d and Cx between 1 and 1.2, and a third quotient between L and Cx between 4 and 7.
