长寿可靠的电力系统电力系统是飞船核心组成部分,它们必须能够在极端环境条件下仍然保持极高的可靠性,因而随着现代飞船的发展,对其电力系统的要求越来越苛刻。尽管脆弱性是现代电子设备的通病,但是,航天器的耐用性往往会让人感到震惊:38年前发射升空的旅行者号飞船至今仍在工作,向我们传回关于太阳系边缘的重要信息。这艘飞船每秒钟能够有效处理81000条指令,而相比之下,
Longevity Reliable Power Systems Power systems are at the heart of the spacecraft and they must be able to maintain extremely high levels of reliability under extreme environmental conditions. As modern spacecraft evolve, its power system requirements are becoming more demanding. While fragility is a common problem with modern electronic equipment, the durability of the spacecraft can often be alarming: the spacecraft launched 38 years ago is still working, sending us back important information about the fringe of the solar system . The spacecraft can effectively handle 81,000 instructions per second, while in contrast,
