AXIAL TURBINE Russian patent published in 2021 - IPC F01D5/03 F01D5/28 F01D5/30 

FIELD: turbine production.

SUBSTANCE: turbine assembly is proposed containing an axial turbine containing an axially arranged sequence of rotor sections 10, each of which contains outer ring 14 and rotor blades 2, wherein the outer rings of the rotor sections are connected to form a rotating outer case, and the rotor sections are made of reaction-bound silicon nitride. The turbine assembly contains outer shell 16, which provides a structural support for the axial turbine, wherein the outer shell is made of dense silicon nitride (DSN). In the proposed axial turbine, rotor sections 10 are mounted on the internal part of outer shell 16. Outer shell 16 and rotating outer case (2, 4) are designed to rotate together. The axial turbine contains an axially arranged sequence of stator sections 12 containing internal hub 20 and stator blades 6, while internal hubs 20 of the stator sections are connected to form stationary shaft 8.

EFFECT: invention makes it possible to increase the mechanical strength of the turbine assembly, as well as to increase its operating temperature.
