Abstract

The accuracy of performance data obtained from instrumentation associated with a wind tunnel test facility is determined by a comparison of empirically and analytically determined performance data associated with a combustorless gas turbine engine reference model. The reference model includes a housing (30) terminating in an exhaust nozzle (85) of standard geometry for which empirical performance data exists. A plurality of apertured plates (130-145) spaced from each other and other reference model components by spacer rings (165-185) adjust airflow through the reference model to correspond to that encountered in the actual wind tunnel testing of a combustorless gas turbine engine simulator.
