Modeling of power system plays an important part in modeling of helicopter dynamics system. The precision of turbo-shaft engine model affects directly the fidelity of power system model in process of modeling and simulation on helicopter. Modeling techniques of turbo-shaft engine are studied first, secondly, engine control system model based on main rotor load feedback is proposed and an inner-outer series-wound control loop to adjust engine output power based on feedback control is developed. The control law of turbo-shaft engine power adjustment is designed. Consequently, integrative model of turbo-shaft engine and main rotor on helicopter power system is realized. A simulation example for helicopter power system is given in this paper to validate the integrative model.
