Analytic model of MPM 20 engine depicted within characteristics of its compressor

Mathematical modeling represents an efficient method allowing us to examine properties of a researched object [1]. Realization of mathematic models has become a fundamental part of design of many complex systems. By use of simulation, we can experiment with mathematical model similarly as with the real object without the risk of critical states and with much lower expenses. Modeling represents experimental process that asserts to the examined original, the real object (or the modeled system) unambiguously another physical or abstract system. The article deals with approach to virtual modeling of a compressor in a small turbojet engine. This article will present design of analytic model of a jet engine (MPM-20 engine in particular) and its graphical depiction into its compressor characteristics.
