ABSTRACT:
The present invention provides a system, including apparatus and method, using a National Bureau of Standards (NBS) traceable laser velocimeter for in situ calibration of a traversing static pressure probe used to determine a velocity distribution in an air metering bellmouth for testing aircraft gas turbine engines. The invention is particularly useful for large fan-jet engines may be used to calibrate rake mounted probes capable of wall-to-wall stream static pressure survey measurements.
