TURBO MACHINE NOZZLE BLOCK OF WHICH IS INSTALLED ON COMBUSTION CHAMBER WITH WALLS MADE FROM COMPOSITE MATERIAL Russian patent published in 2010 - IPC F01D9/02 

FIELD: engines and pumps.

SUBSTANCE: turbo machine includes annular combustion chamber with internal and external walls made from composite material with ceramic matrix, and nozzle assembly of high pressure turbine, which is rigidly attached to rear edge of combustion chamber. Nozzle assembly of high pressure turbine includes wings of guide blades, which are located between internal wall and external wall of annular channel of gas flows coming from combustion chamber through nozzle assembly. Rear edges of internal and external walls of combustion chamber are continued to rear edge of nozzle assembly and form internal wall and external wall of annular channel of gas flow though nozzle assembly. Wings of guide blades are made from composite material with ceramic matrix and attached by applying the method of brazing to walls of annular combustion chamber.

EFFECT: invention allows simplifying turbo machine design, as well as decreasing its weight.
