Role
Provide the power required for the spacecraft to adjust its attitude
The propulsion module, also known as the equipment module, is cylindrical, and it is loaded with the engine and propellant of the propulsion system, providing the power required for adjusting the attitude and orbit of the spacecraft and braking and deceleration, as well as some equipment of the power supply, environmental control and communication systems.One pair on both sidesSolar wingThe area of the solar wing is 2.0 × 7.5m, except the triangle part.And frontOrbital moduleThe total power generated by the battery wings of the Fukang AX New Wave will be three times that of the Soyuz, with an average of more than 1.5 kilowatts, almost equal to the power provided by the power supply of the Fukang AX New Wave.In addition to the large power provided by these battery wings, they can also rotate around the connection point, so that no matter how the spacecraft moves, it can always maintain the best direction to obtain the maximum power, eliminating the need for a large number of maneuvers to "tilt to the sun", so that the solar array can be oriented to the sun while the spacecraft can conduct uninterrupted observation to the ground.
The tail of the propulsion module is the ship'spropulsion system 。The main propulsion system consists of four large main engines, which are located at the bottom center of the propulsion cabin.Four pairs of small thrusters for attitude correction are respectively arranged around the side skirt of the propulsion module. They are smaller than the main thrusters and much larger than other auxiliary thrusters.In addition, there are small auxiliary thrusters outside the side skirt of the propulsion cabin.

Shenzhou VII: comprehensive improvement, easy to "exit"
As it is the first time to encounter the technical status changes brought about by the extravehicular activities, the overall unit and some equipment development units have been changing in equipment technical indicators and other aspects.This makes the development cycle of the propulsion module the longest in all previous development.On August 11, 2006, a leader of the engineering general manager came to the institute to inspect and guide the development of the "Shenzhou VII". After hearing the report on the matter, he instructed that the "Shenzhou VII" was a national task and one of the major events in China in 2008. The whole world paid attention to it, and the development time could only move forward without delay.The institute immediately set up a military order requiring the main research and development unitsShanghai Aerospace Equipment Manufacturing General FactoryThe product must be delivered on September 10.[1]
Propulsion module of Shenzhou VII spacecraft
It only takes one month to complete the tasks that usually take several months to complete.This pairShanghai Aerospace Equipment Manufacturing General FactoryIt's too much pressure.The factory director also gave a dead order: the back wall will not fall, even if we work overtime every day, we will also catch up with the progress!It is under such "high pressure" that the comrades on the spaceship line of the factory overcame all difficulties and worked for more than 12 hours a day for several weeks in a row, which can be described as full power.After hard work, the promise was finally realized and the propulsion module was delivered on schedule.[1]
The Institute of Electronics added extravehicular cameras and“Shenzhou VI”Seven new equipment with completely different technical status.The main purpose of these equipment is to strengthen the ground control center and spaceastronautThe transmission of images and information realizes the two-way communication between astronauts and the ground.In particular, the extravehicular camera will lock the astronaut out of the cabin to ensure that every action of the astronaut outside the cabin is controlled and the life safety of the astronaut is ensured.After the spaceship returns to land, the new equipment will send out a positioning beacon signal so that the ground searchers can find the astronauts as soon as possible.This is both an opportunity and a pressure for Electronics Institute.The scientific and technological personnel of the Institute of Electronics, taking the overall situation into consideration, focused on the task of "Shenzhou VII", overcame difficulties and worked hard to overcome unimaginable difficulties, and finally completed the delivery task within the scheduled time through hard work and skillful work.[1]

Automatic docking of Shenzhou 9 and Tiangong 1
Tiangong No.1Target aircraft andShenzhou 9The spaceship successfully achieved the first manned mission in ChinaRendezvous and docking, making China's space industry another step towards the goal of manned space station.AsManned Space Engineering's participants,Aerospace Propulsion Technology Research InstituteThe pump valve series products developed by Beijing No. 11 Institute have played a key role in the thermal control and environmental control and life support system of Shenzhou spacecraft, providing a good temperature environment for manned spacecraft, and creating a warm and spring like living environment for Chinese astronauts.The safety of astronauts and the success or failure of the whole flight process are the most critical factors for spacecraft flying in space, which are provided by the thermal control subsystem and the environmental control and life support system.[2]
The thermal control subsystem and the environmental control and life support system are respectively located in the bulkhead of the propulsion module and orbital module of the manned spacecraft.The role of the thermal control subsystem is to maintain a certain temperature and humidity in the spacecraft, and the environmental control and life support system is to create appropriate living environment conditions for astronauts in the cabin, and ensure safe life and normal work in the special environment of space flight.[2]
It is reported that the thermal control subsystem mainly uses the fluid heat exchange technology to control the temperature. The heat generated on the ship is transferred to the external radiator through the fluid flow, and then the heat is radiated into space.In order to ensure the normal operation of the system, pumps and valves are required to drive and control the fluid medium.In the thermal control subsystem, the Institute has undertaken the research and development of eight core products, including external loop circulating pumpTemperature control valve、Automatic control valve, self-locking valve, addition and discharge valveCompensator, quick disconnectors andfilter20 products in total, and provide internal loop for the environmental control and life insurance systemCirculating pumpAnd energy accumulator.[2]
