据中国载人航天工程办公室消息,9月12日,我国在文昌航天发射场成功组织实施长征十号系列运载火箭第二次系留点火试验,按计划完成了全部预定系留点火试验。
当天15时00分,随着试验指挥中心下达点火指令,火箭一子级试验产品7台发动机同时点火,按预定程序完成多项试验流程,试验总时长320秒,重点考核了火箭一子级7台并联发动机低工况工作和二次点火启动工作能力,获取了完整的试验数据,试验取得圆满成功。截至目前,计划进行的两次系留点火试验已全部完成,全面检验了火箭一级七机动力系统性能和回收段工作程序设计的正确性和可靠性,标志着长征十号系列运载火箭初样研制工作取得阶段性突破。
长征十号系列运载火箭系留点火试验,按照循序渐进、逐步验证的思路,围绕一级七机并联发动机动力系统性能验证、回收及重复使用验证两个目标分步推进实施,目的是获取一级七机并联工作状态下的真实载荷环境特性,并对回收段工作程序进行验证,是释放首飞风险的重要手段。
目前,我国载人月球探测工程研制工作进展顺利。今年6月中旬以来,相关试验工作多线并举、密集实施,梦舟载人飞船、揽月着陆器、长征十号系列运载火箭等接连取得进展,文昌航天发射场相关配套设施设备建设正在稳步推进。后续,长征十号系列运载火箭将陆续开展飞行试验验证工作。(记者 甘晓)
