The Shenzhou spacecraft is self-developed by China, has completely independent intellectual property rights, and is equivalent to or superior to international third-generation manned spacecraft technology.

The Shenzhou spacecraft uses a three-chamber section, which is composed of a return capsule, an orbital capsule, a propulsion module and an additional section, and is composed of 13 subsystems.

Compared with the third-generation foreign spacecraft, the Shenzhou spacecraft has the characteristics of a high starting point and the ability to stay in orbit and utilize it.

The Shenzhou series of manned spacecraft were launched by the Long March 2F rocket specially developed for it. The launch base is the Jiuquan Satellite Launch Center and the recovery location is on the grassland in central Inner Mongolia.

: China’s first manned spacecraft structure. The spacecraft structure is divided into four parts: orbital module, return module, propulsion module, and additional section.

The orbital module is in the shape of a barrel and is where astronauts work, live and rest.

The interior layout design of the orbital module has been adjusted to facilitate the installation of application system equipment and astronaut food and drinking water devices.

There is a hatch at the bottom of the rear end of the orbital module through which astronauts can enter the return capsule.

There are two solar cell wings that look like bird wings on both sides of the outer surface of the orbital module. The electrical energy required by the orbital module is provided by these two battery wings.

The return capsule is the only section of the manned spacecraft that returns to Earth. The astronauts are in the return capsule when the spacecraft takes off, ascends to orbit, and returns for landing.

The return capsule of Shenzhou 6 is shaped like a bell, and its hatch is connected to the orbital module. Astronauts can enter the orbital module through this hatch.

The return capsule is the command and control center of the spacecraft, and the astronaut's seat is installed in the capsule.

The astronauts lie on the seats when the spacecraft takes off, ascends and returns to the ground.

The return capsule is also equipped with instruments and equipment that need to be monitored and operated by astronauts during flight. Through these instruments, astronauts can judge and understand the working conditions of the spacecraft at any time, and can also manually intervene in the work of the spacecraft's systems and equipment when necessary.

The propulsion cabin is also called the instrument cabin or equipment cabin.

The propulsion cabin is 3.05 meters long, 2.50 meters in diameter, and 2.80 meters in diameter at the bottom.

Install propulsion systems, power supplies, orbital braking, and provide oxygen and water to the astronauts.

It is cylindrical in shape and carries the engine and propellant of the propulsion system inside, which provides the spacecraft with the power needed to adjust its attitude and orbit and brake and decelerate, as well as some equipment for power supply, environmental control and communication systems.

There is a pair of solar wings on each side. Excluding the triangular part, the area of ??the solar wings is 2.0×7.5 meters.

Combined with the battery wing of the front orbital module, the power generated will be three times that of the Soyuz, with an average of more than 1.5 kilowatts, which is almost equivalent to the power provided by the power supply of the Fukang AX new wave car.

In addition to providing a large amount of power, these battery wings can also rotate around the connection points. In this way, no matter how the spacecraft moves, it can always maintain the best direction to obtain maximum power, eliminating the need to "tilt towards the sun".

A large number of maneuvers can be carried out to ensure the orientation of the solar array to the sun and at the same time conduct uninterrupted observation of the earth by the spacecraft.

The tail of the equipment compartment is the propulsion system of the spacecraft.

The main propulsion system consists of four large main engines, which are located in the middle of the bottom of the propulsion cabin.

Four pairs of small thrusters for attitude correction are arranged around the side skirt of the propulsion cabin. They are smaller than the main thrusters, but are much larger than other auxiliary thrusters.

In addition, there are small auxiliary thrusters outside the side skirts of the propulsion cabin.

The additional section is also called the transitional section. Shenzhou-1 launch time: November 20, 1999, 6:30 minutes, 7 seconds. Shenzhou-2 launch time: January 10, 2001, 1:00:3 seconds. Shenzhou-3 launch time: 2002

The "Shenzhou-1" spacecraft was launched from the Jiuquan Satellite Launch Center at 6:30 on November 20, 1999 by a new Long March launch vehicle. The spacecraft's return capsule successfully landed in the central area of ??the Inner Mongolia Autonomous Region at 3:41 the next day.

For the first time, this launch adopted a new model of vertical assembly and testing of the spacecraft and rocket complex in the technical factory, and vertical transportation of the entire assembly to the launch site for long-distance testing of launch control.

Our country's newly built land and sea-based aerospace measurement and control network that complies with the international standard system based on the original aerospace measurement and control network was also put into use for the first time in this launch test.
