The Peculiarities of Applying CAD/CAE Systems for the Primary Combustion Chamber Flame Tube Cycle Life Prolongation of the Tactical Military Aircraft Afterburning Turbofan Jet Engine

Abstract In this article, the computational simulation of workflow in primary combustion chamber flame tube afterburning turbofan jet engine (ATJE) on tactical military aircraft was carried out. The geometric model a created and adapted to perform interrelated calculation thermal stress-strain behaviour walls influenced by operational loads during workflow. Quantitative qualitative analysis results conducted, connection between peculiarities characteristic damage tubes, detected operation, established. possibility using modern CAD/CAE systems solve scientific tasks towards maximizing cycle life potential main primarily important components ATJE assessment basis their exhaustion degree determined.
