Mathematical Modeling of Operating Process Parameters of a Mixed-flow Turbofan Engine with an Afterburner

Abstract

The article provides a brief analytical review of mathematical models of the working process used to study the parameters and characteristics of a gas turbine engine at all stages of its creation and operation. It is shown that the first-level mathematical model can be used for the estimation of parameters and characteristics under real operating conditions that differ significantly from the calculated ones. A mathematical model of a mixed-flow turbofan engine with an afterburner is proposed in the article; the construction principle and structure of the mathematical model of the engine are given. The model allows solving various problems associated with calculating the performance of a mixed-flow turbofan engine with an afterburner in a wide range of external conditions and engine operating modes.
