A number of Hubei creates "asking the sky" to the "Tiangong"

At 14:22 on July 24th, the Long March 5 Yao Three Load Rockets equipped with the Tiantian Experimental Cels was launched at the Wenchang Aerospace launcher in my country. Ask the Tianjin experimental compartment and the Rockets to be separated and entered the scheduled track, and the launch was successful. In the follow -up, the questioning compartment will be met with the spatial station combination in accordance with the predetermined procedure.

Two years ago, on July 23, 2020, the "Long March 5 Yaoyao" launch vehicle took off from the Wenchang Aerospace launcher, holding the "Tianwen No. 1" Mars detector and embarked on the neighbor of the nearby on the earth -Mars The long road.

Two years later, on July 24, 2022, the "Long March 5" carrier rocket sent the "Ask Sky" experimental compartment into space.

The first experimental cabin of China Space Station

In this launch mission, 42 Aerospace Technology Fourth Hospital provided all the cabin movement and static structure sealing products for the "Ask Sky Experiment Cels". "The fire", the aerospace Zhixin Kongtian team helped the space station to achieve a minute -level task plan, and many "Hubei made" smoothly escorted the "Ask Heaven" to the "Tiangong".

Hydrogen consumer ignition device ignite the rocket

Fire "the first fire"

The hydrogen -eliminating ignition device developed by 42 Aerospace Courtyard, as always, escorted the "Long March 5 B" as usual and successfully completed the mission.

In order to ensure that the launch was unattended, Yang Yuwen, a 42 system center developer, settled in the launch base one month in advance to escort the launch task.

"Long March 5 B" will discharge low temperature hydrogen to the environment around the launch platform before the engine ignition. "The combustible gas group formed by these hydrogen and air mixed with air, when the concentration reaches a certain range, once it encounters electrostatic or bright fire, it will explode or blast. Serious consequences. "Yang Yuwen introduced.

The hydrogen -consuming ignition device can ignite the "first fire" launched by the rocket within 2 to 3 seconds before the rocket engine work. Ensure the safety of the launch of the carrier rocket.

This device uses high safety pharmaceutical materials and advanced precise control technology to ensure that it can be "on time and accurate" to fire. After the hydrogen is eliminated, it can "turn off" in time.

"This device implements a double -layer protection design, which 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." Yang Yuwen said.

It is reported that the research and development technology of hydrogen anti -demand and ignition device is the core technology conversion of solid propulsion agents that have been precipitated for more than 50 years. Relying on independent innovation and production, breaking through many key technologies. At present, this technology has reached the world's forefront and domestic leading level. The development of the space industry provides motivation.

42 Instant sealing safety protection for the questioning compartment of the sky

In order to ask the sky experimental

Provide seal security protection

The 42st Hospital 42 provides the cabin and door -to -door sealing products for the test cabin, which can provide a sealing system with a strict seal for the cabin structure, which plays an important role in the isolation cabin and the outer space and the inside environment. "These sealing products can not only prevent radicals outside the cabin, tolerate various rigorous tests of the space environment, but also ensure that astronauts live in life and work during space and the normal operation of the instrument instrument instruments in the cabin." Four Wang Jiang, deputy chief president of the 42 insulation layers and sealing rubber series in the hospital.

According to reports, this product uses special polymer materials. The abrasion resistance and gas tightness are dozens of times the ordinary rubber material. The service life is longer and the reliability is higher. The sealing parts will not generate electrostatic adsorption during use. The product successfully undergone 80,000 fatigue tests on the ground, and passes environmental tests such as low voltage (vacuum), high and low temperature, and weight loss.

Ask the Tianjin Experimental Class to implement a fast meeting with the core compartment, and form a two -cabin and one -sharing structure combination with the core compartment docking.

"The cabin combination and the cabin of the space station are independent rooms. The cabin door is an important institution connecting and isolated space stations. Song Dan, one of the heads of the development of the seal, said Song Dan, one of the heads of the sealing part.

The maximum diameter of this sealing product is close to 3 meters, the perimeter length is 9 meters, and the error does not exceed 0.01 mm. It is equivalent to the accuracy of 1/5 of a hair shit. The test of the rail use is expected to be more than 25 years.

Since the Shenzhou manned spacecraft flight in 1999, 42 four houses have provided tens of thousands of sealing products for the overall unit unit of the spacecraft, with a one -time inspection rate of 100%.

Aerospace Intelligence Assist Space Station

Realize the minute -level task planning

What experimental equipment can be transported in the test compartment? When is the best time to launch? When is the best docking time with the space station? How to reasonably arrange the space staff's outlet maintenance, rail training, space teaching, space experiments, etc.?

The launch of the test compartment and the connection with the space station need to coordinate hundreds of thousands of resources, which is completed by multiple technology centers. Not only the task is huge, arduous and complicated, but also has mutual impact and restrictions between tasks.

How to quickly find the optimal solution at the limited condition restriction and the shortest time, which is inseparable from the space station operation "big steward" -the space station operation planning comprehensive management system.

The empty team of the Aerospace Science and Advanced Institute of Institute of Intelligence and Information Security (Wuhan) Co., Ltd., as an important supporting unit for the construction of space station operation planning system, supports the development of comprehensive management system in the domestic space station operation planning plan, and realizes the task planning of my country's space station mission planning. Manual planning to automatic planning milestone leaps.

The person in charge of the team introduced that the tasks that had been completed several weeks, and now they can allow dozens of to hundreds of users to submit the task requirements, and the task planning scheme can be generated within the minute level. The system effectively solves the technical problems of the rapid solution of complex tasks and achieves efficient synergy of multi -users.

Early task planning was manually arranged by the designer. The space station planning comprehensive management system developed by the Aerospace Smart Sky Team can not only automate the arrangement tasks, but also greatly improve the efficiency and accuracy of the arrangement. The team innovatively developed software interface, which is convenient for astronauts to quickly read the specific requirements and resource needs of the task when performing the task in accordance with the timeline.

At present, the space station operation planning management system will continue to ensure the future space journey of astronauts.
