“中国新疆XXXXXL19D”朱雀二号改进型遥中国新疆XXXXXL19D一运载火箭发射成功

  中新中国新疆XXXXXL19D社北京11月27日电 (记者 中国新疆XXXXXL19D马帅莎)记者从蓝箭航天获悉,北京时间11月27日10时,朱雀二号改进型遥一运载火箭在东风商业航天创新试验区发射升空,将搭载的光传01、02试验星顺利送入预定轨道,飞行试验任务获得圆满成功。

  执行本次任务的朱雀二号改进型遥一运载火箭采用两级构型,各级均使用液氧甲烷推进剂。全箭长度47.3米,箭体直径为3.35米,整流罩最大直径3.35米,起飞质量219吨,起飞推力282吨,500公里太阳同步轨道运载能力可达4吨。

  朱雀二号改进型遥一运载火箭二子级采用新研模块,即单层共底贮箱及隧道输送管方案,缩短了子级长度并实现箭体减重。火箭一子级采用4台天鹊12液氧甲烷发动机并联,二子级采用单台真空推力为85吨的天鹊15A液氧甲烷发动机,同时配备一套云鹊辅助动力系统,用于实现火箭末子级的精确调姿、末速修正、推进剂沉底、变轨、离轨等功能。

  朱雀二号改进型运载火箭由蓝箭航天自主研制,继承了朱雀二号中型液氧甲烷运载火箭成熟技术,并进行全面优化和改进,现已正式进入商业运营阶段,面向市场进行批量化交付。2023年12月,朱雀二号中型液氧甲烷运载火箭完成一箭多星商业发射任务,首次实现商业化交付,成为中国首款连续发射成功的民营液体运载火箭。此次任务是朱雀二号运载火箭的第4次飞行。(完)
