国内民营航天企业“零壹空间”第二次开展单级固体火箭飞行试验

太空来电2018/09/07 23:16:58太空来信

综合北京零壹空间科技有限公司（以下简称“零壹空间”）近期发布的消息，该司研制的亚轨道商用火箭OS-X1，于2018年9月7日12时10分03秒在酒泉卫星发射中心的戈壁中发射成功。

OS-X1火箭又名“重庆两江之星”，是OS-X系列的第二发火箭。全箭总长10.2m，箭体直径0.85m，起飞重量8.1t，起飞推力35t，飞行速度4.5马赫。该火箭全程大气层内飞行，最大飞行高度约35km，飞行时间200秒，飞行距离169km。

据悉，本次飞行试验验证了电气系统和控制系统的关键技术的正确性与可行性，该司即将首飞的主力商用载具OS-M运载火箭将采用与本次飞行试验相同的综控机、惯组、伺服、电池等核心产品技术状态，导航、制导、控制的算法及飞控软件也将在此基础上进行进一步创新设计。本次试验进行了热防护材料进行搭载验证，通过飞行试验的仿真，考核热防护方案的正确性和可靠性。OS-M运载火箭地面转运、吊装、起竖设备与OS-X1火箭一致，在本次试验中得到进一步验证。

据长光卫星公司相关人士发布消息，该司与零壹空间合作，协调发射时刻和卫星过境时间，首次从太空中拍摄了火箭发射升空的视频。

我去！卫星拍摄，这么牛。感觉好想很快就开始转弯，为啥呢，其他运载火箭没看过这么快转弯的，倒是有点像导弹了
