Abstract
A rotary assembly includes a fan disk including a tooth with an upstream face; a platform mounted on the tooth; and a shroud mounted at the upstream end of the disk. The platform, at its upstream end, includes a step with a radial portion that is extended by an axial portion to form a substantially L-shaped longitudinal section. The axial portion radially retains the platform against the tooth. The radial portion extends along the upstream face of the tooth and includes an opening for having a fastener element passing axially therethrough to mount the shroud on the disk. A face of the shroud includes an element that projects and passes through the opening and comes into contact with the upstream face. The element extends from the face of the shroud over a length that is longer than a thickness of the radial portion of the step of the platform.
