| Abstract | ||
| This paper presents a physics-based, detailed nonlinear dynamic mathematical model (MTCturb) of a micro SR-30 gas turbine engine (GTE) using a component matching method. The model integrates individual component of the gas turbine engine capturing thermodynamic and aerodynamic interactions through nonlinear dynamic equations. MTCturb is designed to predict the engine shaft speed (RPM) response with fuel flow as the primary input, accurately simulating both transient and steady-state performance under varying operating conditions. The model is validated against experimental data and high-fidelity simulation results from GasTurb 10, demonstrating strong agreement and confirming its accuracy and predictive capability. Additionally, a graphical user interface (GUI) is developed in MATLAB to enhance model accessibility, enabling users to interactively visualize simulations, adjust input parameters, and analyze system responses. This work provides a valuable tool for control design, optimization, and further research on gas turbine dynamics. | ||
