In order to avoid radial pressure gradients in the blade system in turbo machines, it is proposed to change the channel profile such that inside each stage, a cylindrical or conical profile is changed to an essentially hyperboloidal. Hereby, the hyperboloid emerges with a generatrix forming an inflection tangent to the direction of flow in the transition between stator and rotor blades. <IMAGE> |
