PERFORMANCE PREDICTION OF A TURBOSHAFT ENGINE THROUGH THE USE OF LOSSES MODELS

The aim of present research is performance simulation of axial flow turbine by using of onedimensional modelling method. As respects the importance of modelling for performance prediction and optimization in initial designs level, in following work, that is based on one-dimensional modelling method, after the presentation of solution algorithm by trial and error method and introduction of different loss models for modelling, this method were examined for a turbo shaft engine and compared with experimental results. Comparison of the results with experimental data shows so good adaptation. Also according to these results, Kacker and Okapuu’s developed model gave the closest results to the reference data.
