This document defines the process steps involved in collecting and processing engine test data for use in understanding engine behavior. It describes the use of an aero-thermal cycle model for reduction and analysis of those data. The analysis process may include the calculation of modifiers to match the model to measured data, and prediction of engine performance based on that analysis
An accurate engine system model is required to support engine and aircraft system development. This SAE Aerospace Information Report (AIR) documents the process of matching an engine cycle model to test data and identifies common terminology to facilitate communication among all interested parties.
