Nozzle Guide Turbine Vane

Product name：Nozzle Guide Turbine vane special parts for aircraft engines

The gas turbine guide blade/vane, including the blade body, is also provided with a single inner cavity in which an impact tube connected with the cold air circuit is installed. A jet slit through the leading edge of the impact tube is provided on the leading edge of the impact tube, and the jet slit is used for jet impact cooling on the inner wall of the leading edge of the blade after the cold air in the inner cavity passes through it. The outer wall of the leading edge of the blade is also provided with multiple groups of cross gas film holes through the leading edge of the blade. The first gas film hole in the cross gas film hole group is perpendicular to the outer wall of the leading edge of the blade in the blade section, and has an Angle of 30° ~ 60° with the blade section. The gas turbine guide blade can greatly reduce the casting difficulty of the guide blade, have better cooling effect, more uniform temperature field, and reduce the divergence of cold air flow, so that under the same gas volume and cold air volume, the gas film covering effect formed by cold air flow on the outer wall of the leading edge of the blade is better and the cooling effect is better.
