“7x7x7x任意槽2023官方进口”日本“埃普西隆S7x7x7x任意槽2023官方进口”火箭发动机再次在燃烧试验中爆炸

  中新7x7x7x任意槽2023官方进口社东京11月26日电 (7x7x7x任意槽2023官方进口记者 朱晨曦)日本新型固体燃料火箭“埃普西隆S”26日在鹿儿岛县种子岛宇宙中心进行发动机燃烧试验时发生爆炸。

  据日本广播协会电视台报道,当地时间26日8时30分左右,日本新型固体燃料火箭“埃普西隆S”第二级发动机在日本鹿儿岛县种子岛宇宙中心进行燃烧试验时发生爆炸。报道称,燃烧试验原计划约为120秒,“埃普西隆S”火箭第二级发动机在试验开始49秒后发生爆炸并引发火灾。相关部门对现场开展了灭火7x7x7x任意槽2023官方进口行动,目前尚未发现有人因这起爆炸伤亡。

  这是“埃普西隆S”火箭第二级发动机第二次在燃烧试验中发生爆炸。去年7月,由于火箭内部点火装置的金属部件发生部分熔融,“埃普西隆S”火箭第二级发动机在日本秋田县能代火箭试验场进行燃烧试验时发生爆炸。

  据《朝日新闻》报道,“埃普西隆S”火箭原计划在本年度进行发射,本次爆炸将导致发射计划受挫,并对日本宇宙开发造成影响。

  日本内阁官房长官林芳正当日在记者会上表示,包括“埃普西隆S”在内的火箭研发对日本宇宙开发至关重要,日本宇宙航空研究开发机构将就此次燃烧试验中发生的异常展开调查。

  “埃普西隆S”是小型固体燃料火箭“埃普西隆”的改良版。“埃普西隆S”全长约27米,太阳同步轨道发射能力超过600千克,近地轨道发射能力超1.4吨。(完)
