Abstract
A turbomachine rotor wheel includes a disk carrying blades having roots engaged and held in an annular recess of the disk. The roots are connected to platforms for co-operating with an annular gasket mounted in an annular groove of the disk. The annular sealing gasket exerts a resilient force on the blade platforms holding the blades in a proper position for operation while the turbomachine is at rest.
