TURBO-MACHINE Russian patent published in 2012 - IPC F01D5/02 

FIELD: machine building.

SUBSTANCE: turbo-machine comprises a housing provided with guide vanes. In the housing cavity with an option of rotation of bearings a rotor is located, provided with means for fixing the vanes. The rotor includes a coaxial shaft and a cowling, which are is rigidly fastened to each other, by at least two crosspieces equidistant from each other. The crosspieces are made in a shape of plates, either of equal thickness, either with thickness gradually increasing in the direction of contacting surfaces on the interfaces with the shaft and the cowling. The length of the plates corresponds to the length of the cowling. The plates are oriented along the longitudinal axis of the turbomachine rotor. The gaps formed by the facing surfaces of the rotor and the body of the bearing are designed with an option of connection of the turbo-machine working body. The rotor is made with an ability of rotation with angular velocity, which is determined by the relation of peripheral speed of the rotor spinning to the radius of the rotor.

EFFECT: invention allows to increase peripheral speed of the rotor spinning, axial and radial stiffness of the rotor when a minimum mass is ensured.
