System Dynamics of a Single-Shaft Turbojet Engine Using Pseudo Bond Graph

The system performance of a single-shaft turbojet engine is modelled with the pseudo bond graph approach in this paper. This theory is implemented in the in-house software tool ASTOR (AircraftEngine Simulation of Transient Operation Research) to simulate the overall dynamic of the turbojet model engine P200SX. In ASTOR, the transient performance is calculated with dynamic and individual control volumes to determine the three conservation equations.
