Abstract

The invention discloses a turbine movable blades cooling structure of marine gas turbine, and belongs to the field of gas turbine. The turbine movable blades cooling structure comprises a blade root,a blade type pressure surface, a blade type suction surface, a blade leading edge and a blade tail edge; the front part of the blade body is provided with an S-shaped cooling channel with ribs, gas film holes communicated with the S-shaped cooling channel with ribs of the front part is distributed at the front edge of the blade, a middle S-shaped cooling channel with ribs is arranged in the middleof the blade body, a turbulent flow column cooling channel is formed in the tail edge of the blade, and the middle S-shaped cooling channel with the ribs is connected with the turbulent flow column cooling channel; more than three air inlet holes are formed in the bottom of the blade root, more than three air outlet holes are formed in the bottom of a H-shaped groove, and a middle split seam is formed in the tail edge of the blade. The turbine movable blades cooling structure has the advantages that the structure is simple, the machining and manufacturing are convenient, the cooling effect isgood, and the manufacturing cost of the blades is reduced.

Description

technical field [0001] The invention belongs to the field of gas turbines, and in particular relates to a cooling structure for turbine blades of a marine gas turbine. Background technique [0002] With the development of modern gas turbine technology, the inlet temperature of gas turbine turbine continues to increase, and the high temperature resistance of the latest superalloy materials can no longer meet the requirements of turbine blades. In order to ensure the normal operation of the turbine blades in a high-temperature environment and achieve the design life, advanced and efficient cooling technologies must be used to reduce the temperature of the turbine blades. Blade cooling technology can be divided into two types: internal cooling and external cooling. Internal cooling means that the cooling air flows in the inner channel of the blade to absorb the heat of the blade. External cooling means that the cooling air covers the surface of the blade body to isolate the dir...
