摘要：<p>The part i.e. fan (1), has blades (6) fixedly jointed on a disk (4) and circumferentially spaced with one another, and platform forming sectors (10) fixedly formed on the disk between the blades. The platform forming sectors partially define an inter-blade surface (12) that is adapted by an annular flow of air traversing the part. Each blade has a circumferential projection (40) detected in a continuity of the adjacent platform forming sector. The circumferential projection equally participates in the definition of the inter-blade surface. An independent claim is also included for a method for manufacturing a rotating part.</p>
