四、关于航空火箭的作文?
托举着“神舟”五号载人飞船的“长征”二号F型运载火箭在轰鸣声中直冲蓝天,把一条巨龙般的橘红色烈焰留在秋日的戈壁长空。
乳白色的“长征”二号F型火箭起飞重量479。8吨。它是在“长征”二号E型火箭基础上研制的以发射飞船为主要任务的运载火箭,1992年开始研制,1999年首发成功。此前,这种火箭已经成功地将4艘无人飞船送入太空。
作为中国火箭家族中最重、最长的成员,“长征”二号F型火箭采用了55项新技术,使它同时成为中国航天史上技术最复杂、可靠性安全性指标最高的火箭。
这枚火箭首次采用了垂直总装、垂直测试和船、箭、塔组合体垂直运输的“三垂”测试发射模式,改变了过去水平总装、水平运输的模式;首次采用远距离测试发射控制技术,其中先进的光电技术、自动控制技术和弱信号的远距离传输技术均达到国际先进水平。
为了进一步增大飞行中的安全性,它配置有专门的故障检测处理系统和逃逸系统。火箭在待发段和上升段发生故障时,能够自检测、自诊断,发出故障信息给逃逸系统,逃逸系统随即带飞船离开箭体,从而保障航天员的安全。
“长征”二号F型火箭还首次研制了全冗余的控制系统,实现双套制导与稳定控制技术,其中双CPU计算机、三余度伺服机构和双回路稳定平台技术均达到国际先进水平。从发射“神舟”三号开始全面覆盖系统的冗余控制大大提高了运载火箭的可靠性,为实现载人奠定了基础。
为保证火箭高可靠性和高安全性,火箭电器系统就有近4万个元器件。所有元器件都经过了筛选和40多个回合的增长试验,不仅要在模拟飞行环境下达到设计指标,而且在此基础上要有裕度。比如,从火箭发射到飞船入轨只有短短的600秒,但火箭的可靠性增长试验却达到了546小时。这样,就使“长征”二号F型火箭的可靠性指标达到0。97,这就是说发射100发火箭只能有3次出现问题。同时,火箭的安全性指标达到0。997,意味着1000次故障所采取的救助措施只有3次是不成功的。
总之,长二F型火箭是我国设计制造的世界最先进的运载火箭之一。
