A major impediment to the development of component–based engine models is the lack of available component data. These data are usually proprietary of the engine manufacturers and the normally available information is scanty. The estimation suitable component performance map remains, at best, a difficult task. When component performance is not available the nearest method, of estimating compressor performance such as the scaling technique have been used successfully to model the turbine and compressor. In using scaling technique, the difficulty of simulating existing gas turbine is lack of design data available to the researcher, as the manufacturer gives only the bare minimum data required for safe operation of the plant. Without design data it is very difficult to mathematically model the plant. Therefore; this study illustrate how to find the design data with the minimum available information using the basic thermodynamic laws and use of scaling method to produce a new detailed performance map from a known map with their design data.
