MODELING OF A HIGH PRESSURE TURBINE DISC FOR THE AL-31F JET ENGINE

Abstract

This article deals with a description of the creation of a mathematical model for high pressure turbine disc for Saturn-Ljuka AL-31F turbofan jet engine. The Creating a mathematical model is based on modeling in CAD software. Mathematical model was carried out on the bases of dimensional, shape and material disc characteristics, which are available for the particular high pressure engine turbine. The method described below enables relatively fast model creating for the other usage, which enables the counting of critical stress or low cycle fatigue etc. The value of mathematical model depends on the accuracy of required input data for the particular investigated object.
