APPLICATION OF THE METHOD OF SMALL ALTERATIONS TO ANALYSE THE FUNDAMENTAL PARAMETERS OF A SMALL TURBOJET ENGINE MPM-20

Abstract

The presented article describes a mathematical method which analyses the relationship of the thermodynamic parameters of each flow section of a turbojet engine. By using the relations for the jet engine thermodynamic cycle it is possible to determine equations for computing small alterations. These equations can be defined as linear functions that describe particular thermodynamic processes. The method can be used for various purposes e.g. the engine design or diagnostic of engine technical condition.
