“gogogo大但人文艺术正道”哈工大助力长征十gogogo大但人文艺术正道二号成功首飞

  中新gogogo大但人文艺术正道网哈尔滨12月1日电 (李双余gogogo大但人文艺术正道 刘伟)哈尔滨工业大学12月1日对外发布,该校材料科学与工程学院苑世剑教授团队超低温成形整体箱底技术助力长征十二号火箭实现首飞。

  11月30日22时25分,我国首型4米级运载火箭长征十二号火箭在海南商业航天发射场成功发射,将卫星互联网技术试验卫星和技术试验卫星03星送入预定轨道。这是我国新型商业火箭长征十二号的“首秀”,也是海南商业航天发射场建成以来执行的第一次飞行试验任务,标志着中国商业航天发射场实现了从0到1的突破。

  长征十二号火箭燃料贮箱箱底直径4米级,超出国内现有最大流体成形机的制造能力,成为型号研制的瓶颈难题。材料科学与工程学院苑世剑教授团队利用发现的铝合金超低温“双增效应”的反常现象,发明了超低温成形变革性技术,相比流体成形技术,可大幅降低成形载荷。苑世剑教授带领团队与上海航天设备制造总厂紧密合作,仅用5个月时间突破了梯度温度场和壁厚均匀性等关键技术,采用较低载荷成形出国内最gogogo大但人文艺术正道大直径整体薄壁箱底,各项性能指标均优于设计要求,打通长征十二号火箭研制的“卡点”,保障长征十二号火箭按预定进度成功发射。

  长征十二号火箭是目前我国运载能力最大的单芯级运载火箭,首次将中国单芯级火箭近地轨道运力提升至10吨以上,是中国近地轨道运力最强的单芯级火箭,也是我国可重复使用运载火箭原型火箭。长征十二号运载火箭的首飞成功,开启了我国商业火箭新技术、新产业、新模式、新业态的发展新篇章,推动我国商业航天发展战略和航天强国战略,为推进中国式现代化贡献航天力量。(完)
