HIGH-TEMPERATURE TURBINE OF GAS TURBINE ENGINE

摘要

FIELD: engines and pumps. ^ SUBSTANCE: high-temperature turbine of gas turbine engine comprises turbine disks and spaces between them. The said spaces are sealed by the front and rear intermediate disks with cooling holes arranged at the front intermediate disk rim. There are recesses making axial ribs with holes arranged on the inner side of the front intermediate disk rim. The recess surfaces are formed by circumference arcs, while the number of recesses is equal to that of the holes. ^ EFFECT: lower weight, higher reliability. ^ 3 dwg
