The Technology Tree of Xueba

On April 18, Zhou Yu led neutrino communication satellite related project personnel to take a plane to Hainan Wenchang Space Base.

Two days ago, the neutrino communication satellite was transported to Jintian Port by a large transport truck, and shipped to Wenchang Aerospace Base in Hainan. It will arrive here today.

The neutrino communication satellite is too large to be transported by train, which is why Xinghuo Technology chose Hainan Wenchang Space Base instead of other space launch centers.

Zhou Yu and the neutrino communication satellite must arrive in advance, and the engineers of Hainan Wenchang Aerospace Base also need to carry out pre-launch preparations and equipment maintenance.

A young man in work clothes, about 35 years old, walked towards Zhou Yu and his party.

After exchanging warm greetings with Zhou Yu, he introduced himself: My name is Li Dongming, and I'm in charge of your Xinghuo Technology project.

Hello, Li Gong, thank you for supporting us at Hainan Wenchang Aerospace Base. Zhou Yu shook his hand politely.

He didn't underestimate Li Dongming at all because of his age.

Huaxia's talent pool is extremely strong, and there is never a shortage of talents, especially Huaxia likes to cultivate talented young people.

The people who are active in the front line of various departments are generally relatively young people. They already have sufficient knowledge and experience, and can accept advanced technology, which is not inferior to older and experienced people in other countries.

Scientific research, technology, engineering and other fields have always been based on level, not qualifications.

Under the guidance of Li Dongming, Zhou Yu walked towards the Hainan Wenchang Aerospace Base.

On the way, he praised: The rocket of Hainan Wenchang Aerospace Base is very advanced. This should be a technological breakthrough of the launch vehicle of Aerospace Science and Technology Group.

Li Dongming introduced with a smile: This is indeed the case. The Long March 10 B rocket was put into use for the first time. It uses a more advanced liquid oxygen and liquid hydrogen engine, and its payload is larger and stronger.

Only the Long March 10B rocket can carry your neutrino communication satellite.

When we were considering what kind of satellite to launch to verify this rocket, it happened that your neutrino communication satellite was very suitable for the delivery requirements of the Long March 10B rocket in terms of mass and volume, so we chose to cooperate with you.

After Zhou Yu learned about the specific situation, he began to visit Hainan Wenchang Space Base, which is the latest of China's four major space launch centers.

It is located in the southern part of China, closer to the equator, so it can use the power brought by the earth's own rotation to make it easier for the launch vehicle to break through the first cosmic speed and save energy.

In this way, the launch vehicle can carry a little more payload, and every gram of payload in the aerospace field is very precious.

The Hainan Wenchang Aerospace Base is located by the sea, where launch vehicles and satellites can be transported by ship.

It is also the only space base that can launch large launch vehicles and satellites.

Engineers at Wenchang Aerospace Base in Hainan received the neutrino communication satellite, and they began to test the satellite and assemble it with the launch vehicle.

In addition to visiting Hainan Wenchang Aerospace Base, Zhou Yu also has his own work here, which is to sign relevant contracts.

Xinghuo Technology purchases satellite launch insurance from insurance companies. After evaluation, the insurance policy is as high as 200 million yuan. If the launch fails, the insurance company will compensate Xinghuo Technology for more than 20 billion losses.

The insurance company is an enterprise associated with Hainan Wenchang Aerospace Base. From the price of this policy, we can see the confidence of Hainan Wenchang Aerospace Base in this satellite launch.

Xinghuo Technology also signed a contract with Hainan Wenchang Aerospace Base. The launch of the neutrino communication satellite is a commercial launch. The cost of sending the neutrino communication satellite into the predetermined orbit is as high as 800 million yuan.

The cost of a neutrino communication satellite is 20.2 billion yuan, and the biggest cost is 20 billion yuan for a particle battery.

The particle battery of the entire neutrino communication satellite is the most expensive, and Liu Jing was a little reluctant to install a parachute for the neutrino communication satellite.

When the neutrino satellite life critical point is reached, the particle battery can be recycled.

Time passed quickly, and the engineers at Hainan Wenchang Aerospace Base meticulously checked the condition of the launch vehicle.

At 7:45 am on April 20th, one hour before the launch of the launch vehicle, the tower carrying the launch vehicle, which hugged the launch vehicle and the satellite tightly, was moving slowly along the track from the factory to the launch pad.

Only Hainan Wenchang Aerospace Base has such an advanced means of translation of the launch vehicle, allowing the launch vehicle to move towards the launch pad in the best state.

At 8:40 in the morning, there are still 5 minutes before the launch of the launch vehicle.

Holding a telescope, Zhou Yu stood far away from the launch site and looked at the Long March 10B launch vehicle.

The fat carrier rocket stands on the launch tower, and inside the fairing at the top of it is the neutrino communication satellite.

The time is coming to the launch window of the launch vehicle, all personnel have been evacuated, and the launch tower is slowly opened, no longer supporting the launch vehicle.

In the base control center, Li Dongming looked at the perfect data of the Long March 10B carrier rocket, and he confirmed that the launch project was going on normally.

Ten, nine, eight, seven, six, five, four, three, two, one, light the fire.

Li Dongming pressed the launch button of the launch vehicle.

The liquid oxygen and liquid hydrogen engine of the Long March 10B carrier rocket started to ignite. It sprayed out a huge tongue of flame, which quickly vaporized the water in the water tank under the carrier rocket, and a mushroom cloud composed of water vapor rose.

At the same time, the strong recoil force generated by the engine pushed the nearly 100-ton carrier rocket into the air.

Zhou Yu saw the launch vehicle rising rapidly, and soon turned into a small dot and disappeared from sight.

The control center of Hainan Wenchang Aerospace Base kept reporting the situation of the launch vehicle.

Hainan's radar tracking is normal, and the telemetry signal is normal.

Hainan infrared radar tracking is normal, and the telemetry signal is normal.

Qingdao's radar tracking is normal, and the telemetry signal is normal.

The booster is disengaged, and the flight attitude of the Long March 10B carrier rocket is normal.

...

The Yuanwang 5 radar has captured the Long March 10B carrier rocket, the radar tracking is normal, and the telemetry signal is normal.

The Long March 10B carrier rocket has flown out of the radar range of Wenchang, Hainan, and the radar on Yuanwang 5 has taken over control.

The third-stage carrier rocket of the Long March 10 B carrier rocket separated, the second-stage carrier rocket engine ignited successfully, and the flight attitude was normal.

The fairing of the Long March 10B launch vehicle was successfully separated.

The Long March 10B carrier rocket has left the atmosphere, and it has passed the most difficult hurdle.

Long March 10 B carrier rocket, the second-stage carrier rocket was successfully separated, and the first-stage carrier rocket engine was successfully ignited.

The Long March 10B carrier rocket ignited the last stage of the carrier rocket engine, and flew towards the established orbit at a height of 20,000 kilometers above the ground at high speed.

The Long March 10B carrier rocket arrived at the designated position, and the satellite and rocket were separated successfully.

The people in the control hall immediately became excited and kept shouting.

The Long March 10B launch vehicle was successfully launched, and we Huaxia have successfully developed another highly efficient launch vehicle.

When Zhou Yu heard that the neutrino communication satellite had entered the predetermined orbit, he showed a relaxed smile.

Zhou Yu is very confident in the neutrino communication satellite developed by Xinghuo scientists. As long as it can reach the predetermined orbit correctly, it will be able to operate successfully.
