Technique of representation and use of the multidimensional characteristic turbopropfan engine at automated designing GTD and it SAU

Abstract

There was shown author’s method of linear interpolation propfan’s multidimensional characteristic using for modeling turbopropfan engine in a total range of flight conditions and for reduction of environmental tests costs. The offered method considers requirements to mathematical models for the seminatural modelling stand – simplicity, ensuring of sufficient accuracy of result and work, functioning engine’s mathematical model in a mode of real time.
