Parts I and II of this paper report the measurements and analysis of detailed heat flux distributions obtained on the nozzle guide vane (NGV), rotor, and shroud of the full-stage rotating turbine of the Garrett TFE 731-2 engine. Part I includes a description of the experimental apparatus, a discussion of the measurements performed and a discussion of the data analysis procedure. Part II is composed of a presentation of experimental conditions, a discussion of results, and comparison of these results with predictions obtained using a flat-plate technique and with predictions obtained using STAN5. The essential features of the measurement program are that a shock tube is used as a short-duration source of heated air and miniature thin-film heat-flux gages are used to obtain detailed measurements on the component parts. The gasdynamic and physical parameters of the experiment are representative of typical engine operating conditions.
