“黑人巨大BBBBBVBBBBB”首次亮相 黑人巨大BBBBBVBBBBB看长征十二号运载火箭“小传”

  中新黑人巨大BBBBBVBBBBB社上海12月1日电 (记黑人巨大BBBBBVBBBBB者 郑莹莹)北京时间11月30日22时25分,作为中国首型4米级运载火箭,长征十二号运载火箭在海南商业航天发射场成功发射。首飞的长征十二号运载火箭这是第一次亮相,它有自己的特别“箭”术。

  用途:商业火箭。

  优点:中国低轨运力最强的单芯级运载火箭。

  “腰围”:中国首型4米级运载火箭,具体直径为3.8米。而传统的中国长征系列中型运载火箭直径为3.35米。

  “身高”:全箭总长约62米,属于细长“身材”。

  “体脂率”:长征十二号运载火箭不仅“身材”细长,还是“体脂率低”的“健身达人”。依靠新材料的应用、新工艺的升级等,长征十二号运载火箭的贮箱既减重又扩容。

  “骨骼”:长征十二号运载火箭是中国首个应用铝锂合金的运载火箭,其二级贮箱采用了世界先进的第三代铝锂合金材料,不仅重量轻还特别强韧,相较采用第二代铝合金材料的常规长征系列运载火箭,有关结构的重量减轻了10%至15%。

  “发射新招”:长征十二号运载火箭采用新研的牵制释放系统,实现了该系统的中国首次工程应用。具体来说,就是火箭在点火起飞前,牵制释放系统先将火箭牢牢固定在发射台上,当发动机到达75%工况时,系统实施故障检测并在0.3秒内进行快速检测诊断。确认一切正常后,牵制释放系统可靠释放火箭,让其正常起飞。(完)
