Abstract (en)
[origin: EP0709549A1] The assembly consists of a disc which turns about an axis of rotation and has a series of peripheral recesses for the roots of the blades (5), each of which has a platform (6) with two axial rails and a partition (7). Each of the blades has two reinforcing members (9) which extend in planes perpendicular to the disc's axis of rotation between the platform and blade root and on both sides of the partition, forming cavities (10) to receive two adjacent blades. Each cavity contains a seal element (12) and inertia weight (13).
