推进舱

飞船由轨道舱、返回舱和推进舱组成。

The unmanned spacecraft consists of orbit , descent and propulsion modules .

测试表明：该系统点位测量不确定度可达0.05mm，并介绍了系统在某航天器推进舱检测中的应用。

Tests show that the system measurement uncertainty can reaches 0.05 mm . A real application example in aerospace is given .

除此之外，推进舱两侧装有20多平方米的主太阳能电池阵。

In advancement spacecraft has two solar cell wings , attached to the outside of the instrument propulsion module below the descent cabin .

为进一步提高卫星的性能，将蜂窝夹层结构用于“风云三号”（FY3）卫星推进舱和服务舱的承力筒。

The honeycomb sandwich cylinder is applied in the thrust and service cabin to improve the performance of FY-3 satellite in this paper .

下午12时43分，神舟12号在距离地面400公里处进行了首次姿态调整。半小时后，神舟12号返回舱与推进舱分离。

At 12:43 p.m. , Shenzhou-12 performed its first attitude adjustment while 400 kilometers above earth . Half an hour later , its re-entry module separated from the propelling module .

飞船中部的返回舱是飞船的指挥控制中心，航天员乘坐其上天和返回地面。推进舱位于飞船的后部，主要用于飞船的姿态控制、变轨和制动。

It is a airtight structure with a hatch on the top for astronaut to get in and out of the descent cabin and enter the orbital module , and it is the only landing part of the spaceship to return into the air and to land on the earth .
