Energy Optimization Characteristic Analysis of Electromechanical Actuator on More Electric Aircraft

As the concept of more electric aircraft is mentioned, electrical power on aircraft can gradually replace hydraulic energy, pneumatic energy and other secondary energy, in order to achieve the purpose of saving energy. This paper is illustrated by the example of electromechanical actuator, analyzes the energy consumption of equipment and power loss of energy transmission. Appling in multi-domain modeling, it compares power loss with the traditional hydraulic actuator. As well as, it analyzes power loss of the secondary energy transformation device system including generator and hydraulic pump. The results of simulation show that aircraft actuator with electrical energy optimize energy utilization, especially for large passenger aircraft.
