TURBINE OF GAS TURBINE ENGINE

摘要

FIELD: engines and pumps. ^ SUBSTANCE: invention is related to turbines of gas turbine engines of aviation and ground application. Turbine of gas turbine engine includes nozzle vanes installed in external ring arranged on the side of inlet and outlet edges by means of "thorn-slot" joint. Connection from the side of outlet edge is arranged with contact conic surface, external relative to turbine flow path. Thorn of blade with conic surface is aimed to the side of inlet edge, and angle of cone generatrix makes 40Ç80 to turbine axis. ^ EFFECT: increased reliability and efficiency factor of turbine by elimination of parasite leaks of cooling air in zone of nozzle vane outlet edge. ^ 2 dwg
