Abstract:

Turbine tip clearance design and prediction techniques have been limited to analytical methods for lack of an accurate direct measurement device. It was the purpose of this program to substantiate prediction correlations utilizing direct measurements from a laser-powered miniaturized turbine tip clearance device MTCMD previously developed under Applied Technology Laboratory support. The resultant comparisons of measured versus analytically determined clearances based on measured temperatures would be used to verify or to improve the analytical techniques.
