    摘要:

    为完成飞机飞行参数实时测量系统供电,研究了一种由柔性太阳能薄膜、超薄锂电池和电压变化及充放电管理电路组成的自主供电系统,完成了系统性能测试。测试结果表明,光照充足时,自主供电系统可在296 min内将1 800 mAh无电状态超薄锂电池充电至满电,光照稍弱时则需要386 min;超薄锂电池单独给柔性复合传感测量模块供电时,可使模块满负载工作约625 min;太阳能薄膜+超薄锂电池组合式供电经两个晴天两个阴天测试后锂电池电压由4.15 V降至3.51 V,柔性复合传感测量模块满负载工作1 678 min,可见研究的自主供电系统满足飞行参数测量系统长时间稳定供电的需求。

    Abstract:

    In order to accomplish the power supply for aircraft flight parameters real-time measurement system, an autonomous power supply system, which composed of flexible solar film, ultra-thin lithium battery and voltage change with charge-discharge management circuit, is studied. The system performance test is also completed. The test results show that the autonomous power supply system can charge 1 800 mAh ultra-thin lithium battery from no power to full power within 296 minutes, when the light is sufficient. And it would take 386 minutes when light get weaker. When the ultra-thin lithium battery supplied power to the flexible composite sensing and measuring module alone, it could work at full load for about 625 min. When the power supply came from flexible solar film and ultra-thin lithium battery, the lithium battery voltage decreased from 4.15 V to 3.51 V, after two sunny days and two cloudy days, and the flexible composite sensing and measuring module worked at full load for 1 678 min. It is concluded that the autonomous power supply system meets the demands of long-term stable power supply for flight parameters measurement system.
