The purpose of this facility is to obtain detailed flow field measurements for computational fluid dynamic code assessment and flow physics modeling in support of Army and NASA efforts to advance small gas turbine engine technology. <> <>stream Full-Text for the document if it is not available in the NASA Lewis Research Center is.!
