Modeling and computer-aided design of combustion chambers for aircraft engines and gas turbine plants using an expert system

Abstract

The modeling issues of the working process and the design of combustion chambers for aircraft engines and gas turbines are considered. The developed modeling tool is shown: the “AM” expert decision-making system. A brief description of the expert system and module aimed at modeling and designing of the combustion chamber structures is given. The results of the computer-aided design of combustion chambers for the AL-31F aircraft engine and the AL-31ST gas turbine engine are presented. The results obtained are verified on the basis of the basic design and the values obtained using three-dimensional models of the real structure. A comparison of materials selected by an expert system with those used in a real design is performed. The parametric studies results of the various parameters influence of the combustion chambers working process on their design are also shown.
