Modeling and Closed-Loop Transient Analysis Method of Large Bypass Ratio Turbofan Engine
Abstract
As the core aerospace power unit, the high-bypass two-spool separate-exhaust turbofan engine, a typical aerothermodynamic coupling system, exhibits strong nonlinearity within the flight envelope due to dynamic changes in environmental parameters and operating modes, with transient control being a research difficulty for involving multi-steady-state switching and fault risks. This paper built its component-level model via the analytical method based on aerodynamic/thermodynamic principles, solving nonlinear common working equations with the Newton-Raphson method; validated against GasTurb, 6 key steady-state parameters had relative errors
