摘要

The blade (2) is connected to a blade foot (3) which in relation to the rotary axis of the turbine disc (1)is radially extended and has a joining surface at its radially inner side for connecting with the joining surface (6) of the disc. The blade foot seen circumferentially in relation to the disc is formed as a circle segment. Independent claim describes compactor or turbine disc with radially aligned joining faces for fixing blades.
