中国商业卫星发射将首次实践“星座快速构建”模式

2017-04-24 21:36:24   中国青年网

新华社武汉4月24日电(记者黄艳、胡喆)24日,第二个“中国航天日”,中国首家按商业模式开展研发和应用的专业化火箭公司——航天科工火箭技术有限公司与国内客户一次性签订四发快舟一号甲(KZ-1A)固体运载火箭发射服务合同,将在一周之内连续发射4颗卫星,在国内首次实践遥感星座的快速构建,进一步彰显快舟火箭的快速发射能力,标志着中国航天科工快舟系列运载火箭进入批量生产、批量发射阶段,将大大降低生产和发射成本。

这是记者从在武汉市举行的“中国航天日”活动现场了解到的情况。中国航天科工集团第四研究院副院长、航天科工火箭技术有限公司董事长张镝接受记者采访时介绍,这次发射服务采用的KZ-1A运载火箭是一型低成本、高可靠性的通用型运载火箭,采用国际通用接口,主要为300千克级低轨小卫星提供发射服务,具有发射成本低、飞行可靠性高、入轨精度高、准备周期短、保障条件少等特点。KZ-1A运载火箭系统主要由快舟一号甲运载火箭、地面发射系统以及相关配套设备组成。

张镝说:“星座快速构建模式就是短时间内快速发射多颗卫星,让卫星在太空快速组建网络,实现技术应用目标;另一个好处就是可以大幅降低商业发射成本,提升国内商业卫星发射的竞争力。因为现在卫星越做越小、数量越来越多,所以提高发射效率是卫星发射技术竞争的关键之一。”

目前,在国际商业发射中,小型运载发射报价一般为每公斤2.5到4万美元,“而快舟1A运载火箭的报价不到2万美元,快舟11型运载火箭报价不到1万美元,价格极具竞争力。”中国航天科工四院相关负责人介绍说。

中国航天科工集团公司董事长高红卫在24日的航天日活动上表示,在商业航天领域,中国航天科工四院瞄准新一代航天发射与应用的巨大市场,按照“社会性总体院、社会性总体部、社会性总装厂”的发展模式,以武汉国家航天产业基地为依托,通过引入社会资本,探索研发投入资本化的新途径,开创了航天项目商业化的新模式。

据美国航天基金会发布的《航天报告》显示,2015年全球航天经济总量达3353亿美元,其中商业航天占76%。可以预见,未来商业航天将成为我国航天事业发展的新动力,也必将成为建设航天强国的重要推手。
