“WWWWWⅩXXXXX18”中国首型4米级WWWWWⅩXXXXX18运载火箭长征十二号首飞成功

  中新WWWWWⅩXXXXX18网海南文昌11月30日电WWWWWⅩXXXXX18 (记者 马帅莎 符宇群 郑莹莹)11月30日晚,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点火起飞,随后,火箭顺利将卫星互联网技术试验卫星、技术试验卫星03星送入预定轨道,发射任务取得圆满成功。

  长征十二号运载火箭由中国航天科技集团八院抓总研制,火箭全长约62米,起飞质量约430吨,采用二级构型设计,一级采用4台推力1250千牛的液氧/煤油发动机,二级采用2台推力180千牛的液氧/煤油发动机,近地轨道运载能力不少于12吨,700公里太阳同步轨道运载能力不少于6吨,是中国目前运载能力最大的单芯级运载火箭,可根据任务需求适配5.2米、4.2米直径构型的整流罩,支持单星、多星不同轨道发射。长征十二号运载火箭是中国首型4米级运载火箭。4米级直径设计可实现箭体直径与发动机数量的最佳适配。

  据了解,长征十二号运载火箭已经做好进入高密度发射状态的准备,将有效提高中国太阳同步轨道入轨能力和低轨多星座组网能力。

  技术试验卫星03星由中国航天科技集团五院抓WWWWWⅩXXXXX18总研制。卫星互联网技术试验卫星由银河航天承担研制。

  本次发射是长征系列运载火箭的第548次发射。(完)
