摘　　要：航空蓄电池在飞机地面装载与准备、启动发动机以及应急状态下是飞机电气系统的直流电源,在整机电源容量分析(ELA)时需要进行容量分析。在其他飞行状态下,蓄电池由飞机电网充电,是飞机电源系统的重要负载,需要对其进行负载分析。分析了飞机蓄电池ELA稳态计算原理;结合实测飞机电气系统实验模拟设备运行数据,完成了飞机航空蓄电池在不同工作状态下的ELA计算研究。研究表明,正确的蓄电池ELA分析可为飞机电气系统设计中蓄电池选型或机载电子电气设备加改装提供必要技术支撑。Battery was the power supplier of the aircraft during the loading ＆amp; preparing or engine starting,as well as the emergency situation.During these periods,the battery was the direct current power source,and its capacity should be analyzed.During other operating conditions,battery was charged by the aircraft electrical web,and was the essential load of the aircraft electrical system.The electrical load analysis should be carried out.Firstly,the aircraft battery steady ELA theory was analyzed.Secondly,aircraft electrical system simulated equipment in the laboratory was operated,and the test data were collected.At last,the ELA calculation of the aircraft battery was made based on different flight conditions.The study shows that correct battery ELA analysis method can be used as the technology basic not only for battery configuration choosing during the period of aircraft design,but also for aircraft electrical system＇s addition or modification.
