In Wenchang Aerospace launches in Wenchang in my country

Consultation on time

About 495 seconds

Ask the Tianjin Experimental Cels and the Rockets to successfully separate

And enter the scheduled track

The launch has achieved a complete success

Chinese space station

The first scientific experimental cabin

This is the 24th flight mission since the implementation of the manned space projects. The launch of the questioning compartment of the launch is the second cabin section of the China Space Station and the first scientific experimental cabin. Asked about the working cabin, the air gate, and the resource cabin, the take -off weight is about 23 tons. It is mainly used to support astronauts' residence, outlet activities, and launching space science experiments. Manage the space station.

In the follow -up, the test compartment will be met with the core compartment combination in accordance with the predetermined procedure. The Shenzhou No. 14 Aerospace Worker's multiplication group will enter the Qi Tian experimental cabin to carry out the work.

Ask the "Hubei made" on the experimental compartment

"Hubei made" sealing parts make the experimental cabin safe and reliable

In this launch mission, the 42 House of Fourth House of China China Aerospace Technology Group provided all the cabin movement and static sealing products for the "Ask Sky Experiment Crystal". A fire "" Ask the sky "smoothly to the" Tiangong ".

It is understood that all these cabin movements, static structures, and institutional sealing products developed by 42 are resistant to the various rigorous tests of the spatial environment, and also ensure that astronauts live in life and work in space. The normal operation of the instrument and instrument provides reliable long life seal protection, and all performance meets the design indicators.

This time, 42 provided the door of the cabin and the static sealing parts of the "Ask Sky Experimental Cels". These sealing products can provide a strict sealing system for the cabin structure of the spacecraft and space stations. Layer space and supporting cabin's environment plays a vital role. In terms of materials, through the selection of special polymer materials, its abrasion resistance and gas density are dozens of times the ordinary rubber material. Their life expectancy is higher. The reliability is higher. The sealing parts made of this material can withstand the test of strict environment such as the high and low temperature changes of -90 to 200 ° C, and can be used safely for 25 years.

Song Dan, one of the person in charge of the sealing parts, said: "The composition of the cabin and the space stations are independent rooms. It is required that the dense seals of the cabin must be strictly sewed, but also durable, and put forward extremely high requirements for the sealing performance and durability of the cabin door. The styling products must be excellent, 100 % perfect, and care for the safety of the spacemen with heart. "The largest diameter of these sealing products is close to 3 meters and 9 meters per week, but it cannot exceed 0.01 mm errors, which is equivalent to a hair hair. The accuracy of 1/5 of the silk.

The hydrogen consumer ignition device once again ignited the "first fire"

"Long March 5 B" Yao San Lai Rockets successfully sent the space station to the space station to space, and successfully completed the most important part of the "three steps" strategy of my country's manned space project. Construction provides reliable support. This is the third time of the "Long March 5 B". The hydrogen -eliminating ignition device developed by 42 Aerospace Fourth Courtyard. As always, the "Long March 5 B" was fully escorted and the mission was successfully completed and the mission was successfully completed.

The "Long March 5" hydrogen discharge combustion system of the "Long March 5" at 42 can ignite the "first fire" emitted by the rocket emitter within 2-3 seconds before the rocket hydrogen and oxygen engine work. Metal particles flow to eliminate a large amount of low -temperature hydrogen excreted before the rocket launch to ensure the safety of the launch of the carrier rocket.

This device uses high safety pharmaceutical materials and advanced accurate control technology to ensure that it can ignite "on time and accurate". After the hydrogen is eliminated, it can "turn off" in time. Through the implementation of the double -layer protection design, it can not only withstand the high -heat flow shock caused by the launch of the carrier rocket, but also has explosion -proof function, which can avoid safety accidents such as casualties and equipment damage in the device.

"Hubei made" to a comfortable home for astronauts

With the launch of the launch of the experimental compartment of the sky, successfully connects the China Space Station, and the gas flow regulating valve produced by Hongfeng Company of China Aerospace Sanjiang Group in E Central Enterprise Enterprise is equipped with the Askuman Experimental Crystal to take off smoothly. Play an important role in the task.

Hongfeng Company has undertaken the production and production tasks of manned space engineering, which has a history of more than 30 years. Products supported by "space kitchen", "space air conditioning" and "space hospital", starting from God's five, it has been tested and runs normally.

The gas flow regulating valve carried this time is a component of "space and air conditioning". Its main function is to adjust the proportion of cooling gas flow by controlling the amount of mouth of the valve, thereby changing the temperature and humidity of the air in the cabin to ensure aerospace The staff work in the appropriate work environment.

Tang Hui, deputy director of the Aerospace Sanjiang Hongfeng Company, told reporters that the weightless environment in space is very different from the ground, and the reliability of the air -conditioning system is very high.

"Heaven" product reliability requires high requirements, and it is crowded. The plane accuracy of the fan blades of the gas flow regulating valve is a key indicator. With high accuracy, it is also necessary to ensure smooth rotation under the premise of ensuring accuracy. Responsible for processing is Li Gang, the winner of the National May Day Labor Medal. He adjusts the corrected blade errors by hand to ensure that each installation surface of the product meets the design accuracy requirements at the same time. Li Gang used his hard work to ensure the "accuracy of the sky". Let's take Chinese space
