GAS TURBINE Russian patent published in 2007 - IPC F01D1/10 

FIELD: mechanical engineering; gas turbine.

SUBSTANCE: proposed gas turbine has casing closed by covers, shaft installed in bearings of covers whose free end gets out through hole of one of covers, wheels secured on shaft, and intake outlet and middle spaces. Turbine wheels of similar designed are installed on shaft at distance from each other being made in form of disks, each provided with through channel arranged over concentric circles. Inlet hole of each channel opens to end face side of disk coupled with intake space. Outlet hole of each through channel opens to opposite end face. Each through channel is made in form of de Laval nozzle longitudinal axis of each of which in each concentric circle is tilted to side opposite to direction of rotation of disk and is arranged at angle to end face surface of disk to which intake holes of through channels open. Diameter of each through channel decreases in direction to center of rotation. Front, rear and middle shells are installed inside casing and provided with round slots on end face sides into which round sealing rings are fitted being pressed to end face sides of turbine wheels by springs.

EFFECT: increased efficiency.
