7月24日下午3时8分,我国在研的长征五号运载火箭在北京成功进行了芯二级首次动力系统试车。此次试车是我国迄今为止开展的最长时间系统级火箭动力试车,也是长征五号运载火箭转入发射场合练阶段的重要前提,对于按期实现成功首飞具有重要意义。

用于此次试验的长征五号运载火箭芯二级产品,直径5米,总长约11米,使用无毒无污染的液态氧和液态氢作为火箭发动机推进剂。点火后,火箭芯二级动力系统按照真实飞行时序,圆满完成了两次启动点火,考核验证了芯二级模块设计方案的正确性和工作协调性。

长征五号运载火箭不仅是我国首型全新研制的新一代运载火箭,也是我国目前运载能力最大的运载火箭,承担着后续探月工程三期、载人空间站等多个国家重大科技专项发射任务。长征五号运载火箭计划于2016年进行首次飞行试验,目前已进入工程研制决战决胜阶段。
