Patent ID: 6923051

Claim:
A method for evaluating a gas flow characteristic of a gas path component for a gas turbine engine, comprising: providing a source of gas, a chamber including a support member for supporting the component, and a rotatable measurement section located downstream of the component and having therein at least one flow-responsive measurement device; mounting the component with the support member; placing the measurement device at a first location downstream of the component; directing a flow of the gas from the source into the chamber and through the component; flowing the gas exiting the component proximate to the measurement device; making a first measurement of a property of the gas with the measurement device placed at the first location; rotating the measurement device to a second location downstream of the component; directing a flow of the gas from the source into the chamber and through the component; flowing the gas exiting the component proximate to the measurement device; and making a second measurement of a property of the gas with the measurement device placed at the second location.
