Model based simulation and analysis of energy optimization characteristics of more-electric aircraft

More-electric aircraft is an aircraft that uses electric energy to replace the hydraulic energy and air pressure energy, and its secondary energy system is mainly composed of electric energy. To obtain the optimal design of the more-electric aircraft energy system, the generation, distribution and power consumption of aircraft are integrated into a unified system to implement unified planning, unified management, and centralized control of power generation, distribution and consumption. To analyze the optimization characteristics of the more-electric aircraft energy system quickly and effectively, this paper uses the model-based system engineering methodology to study the more-electric aircraft energy optimization simulation platform. A multi physical domain modeling method for electrical equipment is proposed to realize large-scale integrated simulation of the airborne system. The simulation models for energy utilization, energy transmission and energy transformation equipment of the more-electric aircraft flight control system and the traditional aircraft flight control system are established. The energy application characteristics of the two flight control systems are analyzed. Our study can provide effective support for optimization of the energy system of more-electric aircraft.
