A power distribution network system of an electric propulsion aircraft belongs to the field of aircraft power distribution. The direct-current generator power supply serves as main power supply equipment of an aircraft, is arranged in the center of the aircraft and is connected with an engine and a nearest distribution box. All the power distribution boxes are arranged in a multi-step ring shape from the center to the edge of the airplane, the adjacent step rings and the power distribution boxes located in the same step ring are connected with one another, meanwhile, the power distribution boxes need to be arranged nearby according to distribution of loads on the airplane, and a spider net-shaped structure with the center power distribution box as the net center is formed; each distribution box is connected with an energy storage power supply or a direct-current generator power supply which is configured with the distribution box, one distribution box is selected to be connected with a ground direct-current power supply, and the distribution box is connected with a load close to the distribution box. The method has the advantages of higher system redundancy, higher reliability and higher safety.
一种电推进飞机的配电网络系统,属于飞机配电领域。直流发电机电源作为飞机的主要供电设备,设置于飞机的中心位置,与发动机及其最近的配电盒相连;所有的配电盒从飞机的中心至边缘呈多阶梯环状布置,且相邻阶梯环以及处于同一阶梯环的配电盒之间相互连接,同时配电盒的布置位置需要根据飞机上负载的分布进行就近布置,构成以中心配电盒为网心的蜘蛛网状结构;每个配电盒均与各自配置的储能电源或直流发电机电源相连,选择其中一个配电盒与地面直流电源连接,配电盒与与之相近的负载相连。本发明具有更高的系统冗余,更高的可靠性和安全性。
