GAS TURBINE ENGINE

摘要

FIELD: engines and pumps. ^ SUBSTANCE: proposed gas turbine engine features turbine first-stage nozzle vanes arranged on combustion chamber gas collector outlet. Gas collector inner wall rear part is perforated and arranged on first-stage nozzle vane outer part. Its is limited by front and rear circular grooves arranged to receive nozzle vane radial ledges. U-like section compensator is arranged between perforated wall and read circular groove. Perforated wall outer surface is made equidistant from cooled surface of first-stage nozzle vane lower shelf. ^ EFFECT: higher reliability. ^ 2 dwg
