"Shen 9" multiple parts manufactured and produced by Jiangxi enterprises

The successful flight of Shenzhou 9 attracted the attention of the world. The reporter learned from relevant departments on the 17th that space accessories, such as the space precision slip rings, transmitters, and astronauts' seats on the Shenzhou 9 were manufactured by Jiangxi enterprises.

Space precision slip ring: Central nerve Shenzhou No. 9 has a core component developed and produced by Jiujiang's China Shipbuilding Industry Research Institute No. 634, which is the "space precision slip ring." It is understood that this accessory is used at the junction of the spacecraft's battery flap and the spacecraft's hull, and plays a control signal and transmission function in the rotating state of the spacecraft. It is a precision power transmission device that realizes the signal and current transmission of two spacecraft relative rotating mechanisms. Can provide a steady stream of energy for the entire spacecraft.

In the past, it took four years for precision conductive slip rings to go from initial research and development to the delivery of finished products. After receiving the task of developing a precision conductive slip ring for the important parts of Shenzhou No. IX 4, the researchers took pains to work day and night and eventually adopted a new high-voltage transmission technology, which greatly reduced the conductivity. The geometry of the slip ring saves transmission energy losses.

It is understood that the 6354 Institute has a lot of innovations on this Shenzhou 9 and has made significant improvements in terms of technology and performance.

The receiver: The ear of “Shenzhou Jiu” began with the Shenzhou-3 spacecraft. Jiangxi Lianchuang Electroacoustic Co., Ltd. (State-owned No. 4380 Factory) located in the outskirts of Ji’an City accepted the development of the production and transmission device group for China’s manned space flight. Glorious and arduous task. The spacecrafts Shenzhou-3, Shenzhou-4, Shenzhou-5 and Shenzhou-6 all use the dedicated set of telephones developed by the company.

In the Shenzhou V spaceship, Yang Liwei, China’s first "space hero" who flew into space, wore the company's production of a microphone set to send clear and loud sounds from space and send back valuable scientific research information. Shenzhou 6 spaceship astronauts Fei Junlong and Nie Haisheng wear a microphone set that is more advanced in quality and performance. This "Shenzhen Jiuji" also uses the state-owned No. 4380 factory's transmitter, but the technology of the receiver is even higher and more exquisite.

Astronaut Seat: The astronaut seat on the Shenzhou 9 spacecraft with high technological content embodies the intelligence and hard work of all the staff of the China Helicopter Design Institute (602 Institute) in Jingdezhen. The astronaut seat is an important device used to carry astronauts in manned spacecraft man-machine engineering. The sliding slider can be connected with the buffering energy absorbing mechanism to adjust the astronaut's supine posture and the shock absorption function, so as to ensure the safety and comfort of the astronaut under the sports state.

In order to test the anti-seismic capacity, the seat has undergone several high-altitude drop tests. There is also a pad outside the seat, which can be continuously adjusted according to the human body and can play a buffering role. Because of the high technological content of the seats, the entire seat is sometimes obsolete because of deformation and riveting deformation of the weldment. Through technological research, researchers have overcome key problems.

It is understood that 602 also contributed to the "Shenzhou" 5 and "Shenzhou" manned spacecraft No. 6 and took on the astronaut's overweight training equipment. This equipment is a key equipment for selecting astronauts and conducting ground training. one.

Propellant: The propellant that was emptied is located at the Jiangxi Xinghuo Chemical Plant in Yongxiu County, Jiujiang. It is one of the main sources of power for the launch of the carrier rocket to help Shen Jiu. Jiangxi Xinghuo Chemical Factory is one of the key manufacturers of China's propellants. Before 1990s, various types of missile propellants used by the state were shipped from here. Most of the Asian satellites, Long March carrier rockets, and Shenzhou series were added. The injected propellants are from the plant.

The term "raise", a unique term in the space field, means the addition of propellant (or fuel). Refueling often has very strict requirements on accuracy. The amount of propellant added will determine whether the rocket can be accurately put into orbit and whether the spacecraft can operate normally. Without a propellant rocket, there is no space left. If the propellant is not added enough, the rocket will not be able to lift or reach the required altitude. In the mid-air explosion, too much propellant will deviate the rocket from its intended orbit. The launch failed, so the amount of propellant added must be calculated very accurately.

Field Effect Transistors: Indispensable Components Following the successful application of the Shenzhou-1 to Shenzhou-6 and “Chang'e-1” lunar exploration project, the reporter learned from related departments yesterday that the field effect of Jiangxi Lianchuang Special Microelectronics Co., Ltd. Transistors have also been successfully applied to "God 9".

As a voltage-controlled semiconductor device, a field effect transistor is like a human nerve cell or a screw on a car. It is distributed throughout the entire Shenzhou launch system, from ground launch equipment to remote sensing telemetry satellites, ships to spacecraft, and distribution. In various parts of the launch system, it is an indispensable component of spacecraft and satellites. Although people can not intuitively see it, but it dozens of parts of dozens of varieties together, we can ensure the safety and smoothness of spacecraft, remote sensing, telemetry, remote control.
