Abstract
A gas turbine engine having self-cooling seals and methods thereof are provided. The engines include a first component exposed to a high temperature environment, a second component that is not exposed the high temperature environment, and a seal between and in contact with the first and second components to separate a cavity therebetween to define a higher pressure region and a lower pressure region. The seal includes an annular body encircling a longitudinal axis of the gas turbine engine. The annular body has an S-shaped cross-section biased to apply forces against the first and second components, a first and second contact portions in contact with the first and second components, respectively, and holes extending through the annular body that provide passage for fluid flow therethrough and direct the fluid flow toward the first contact portion for cooling thereof.
