Exploratory Investigation for Reducing Labyrinth Seal Leakage in High Pressure Ratio Gas Turbines.

Abstract

The attendant problem of labyrinth seal air leakage in current and advanced high pressure ratio gas turbines is directly related to the limitations of current gas turbine dynamic seal technology. A method of improving the efficiency of labyrinth seals which does not violate mechanical design constraints involves increasing the internal cavity turbulence of the seal. Therefore, an exploratory investigation was undertaken to conceive, design, fabricate, and test several unique labyrinth seal configurations. (Modified author abstract)
