Rebirth: I carry a desktop computer inside me

After several months of research and development, coupled with the guidance of experts from the China Space Center, Deng Lian and the entire R&D and design team initially designed the large-scale space launch vehicle "Fengyun" 1.

The engine is commercially available in China Aerospace and can be used directly to save time and cost.

Of course, in order to meet my own needs, I have also made some improvements.

A liquid hydrogen engine is used.

Since the orbit of the electromagnetic ejection is still not long enough, after de-orbiting, it reaches supersonic speed, so it also needs a powerful engine of the carrier to continue accelerating.

In order to reach the first cosmic speed.

As for the satellite, it is customized to the Hua National Space Center, and the relevant chips and systems are modified and optimized by the artificial intelligence Xiaofeng in Jiang Cheng's body.

The chips used are carbon-based chips and resistive storage.

"Jiang Dong, look, this is our space launch vehicle." Zheng Mo, the chief designer of the carrier next to Deng Lian, said.

In front of him was a large launch vehicle similar to a space shuttle, with a huge belly, like a wide-body airliner.

However, the tail is composed of four huge engine columns, plus the three engines that come with the carrier, which makes it a total of seven engines.

Zheng Mo continued, "In order to ensure stability, our dimensions are as follows, 89 meters long, 32 meters wide (excluding wingspan), 83 tons empty, and 135 tons when loaded with fuel.

Jiang Cheng nodded, "How much can the maximum load reach?" "

55 tons."

Jiang Cheng calculated it, and it was not bad.

In fact, a lot of the weight of the entire carrier here is used to load fuel, and it is impossible to achieve such a high load according to calculations, but because it is an electromagnetic ejection, the maximum load is effectively increased after the acceleration of the most difficult section is solved by electromagnetism.

Deng Lian said, "However, this is theoretical, and we still need to test the specific situation."

"Well, if it is indeed feasible, then our future satellites and even the space bases that need to be built can carry larger space combinations."

"For example, squares, ovals, etc."

Jiang Cheng thought for a while and said, "When I look back, I will carry out the advance design according to the space situation of our carrier load and the plan for future base construction."

"Okay." Deng Lian responded, "I will communicate with the aircraft department at that time." At present, they are also in the preliminary design.

Zheng Mo sighed with some emotion, "With the guidance of Academician Jiang and the China Aerospace Center, I think our commercial aerospace dream will not be too far away."

"That's thanks to your team with sufficient experience in aerospace design and development." Jiang Cheng smiled slightly.

The Zheng Mo in front of him is 66 years old, but he was once a big designer-level figure in the China National Space Center and has experience in the design of the entire rocket.

Therefore, when getting Jiang Cheng's requirements, the design was relatively smooth.

After all, compared to the rocket, Jiang Cheng's launch vehicle requirements are more extensive.

Of course, there is also difficulty.

But Jiang Cheng's side gave space company researchers permission to use the artificial intelligence "Xiaofeng" and Pangu-1 supercomputers, which accelerated the overall design by several times.

"By the way, Deng Lian, quickly make a one-to-one model of the launch vehicle, and conduct a pilot test at the Nanhai Maple Fire Launch Center." Jiang Cheng reminded.

"Okay, I'll arrange that." Deng Lian immediately answered.

He knew that Jiang Cheng was in a hurry and needed to test the battery ejection system built by Haoyan Heavy Equipment Company with a model as soon as possible to see how the effect was.

Under Jiang Cheng's guidance, the entire ejection system was significantly improved.

The ejection is divided into manned and unmanned, and there are two catapult systems, configured with different parameters.

Among them, manned ejection, will carry out certain restrictions, so that the ejection acceleration is controlled within 4 G, but for unmanned vehicles, then the ejection overload can reach 6 G, and the tail speed can be greatly improved.

This is one of the important reasons why the load can be up to 50 tons.

Immediately afterwards, Jiang Cheng simulated the entire vehicle into the virtual laboratory in the body and began to desperately create it.

However, because of the particularity of the atmosphere, Jiang Cheng has no way to simulate it realistically, and can only assist in simulated atmospheric calculations through the powerful Hualong 1 supercomputer.

"Unfortunately, at present, our biofuel engines, it is really not easy to make the launch vehicle go to the sky." Jiang Cheng suddenly sighed, "Engine technology, let's see if there is room for improvement."

Zheng Modao, "At present, our rocket engine technology in China has improved rapidly, but there is still a gap with foreign advanced rocket and space shuttle engine technology, and here is more of a material gap."

"Regarding the material, I'll come and think of a way to do it then."

"Whenever I reach a bottleneck, I think that the huge earth protects us, but also restricts us from going out well." Zheng Mo said, "It would be great if one day, we humans can develop a powerful engine that does not rely on fossil energy, so that the aircraft can easily take off and land on any planet!"

The corners of Jiang Cheng's mouth raised slightly, "Whether it is liquid hydrogen or oil and coal engines, although they are used normally, the specific impulse is too low." I think our own research department should start from the direction of plasma engines.

"Plasma engines, now some countries are also studied, but the problem is that the thrust generated by this thing is too small, only suitable for propelling vehicles in space, not suitable for propelling our rockets, or launch vehicles." Zheng Mo shook his head.

"So our research never ends." Jiang Cheng said with emotion.

However, at this stage, although Jiang Cheng will study, he also understands that he will not be able to find a better way for a while, and before that, building his own space factory is the right way.

When the factory is built in the future, some new technologies and creations may be better developed.

After keeping the matter of this engine in mind, Jiang Cheng continued to stay at Maple Fire Aerospace Company to jointly improve the relevant chips and systems inside the first satellite that was about to be launched.

At that time, Jiang Cheng needs this satellite to help him always grasp the flight attitude and position information of the vehicle.

Otherwise, what you launched yourself, whether it succeeded or not, there is no liaison to report to yourself.

And this satellite, for Jiang Cheng, is also an experiment, if the artificial intelligence operation in the carrier can perfectly achieve its own launch mission, then the future manned launch will have greater certainty.

At that time, many operations do not need to be carried out on the ground, there is a "small maple" to control, when the engine can be started, thrust calculation and control combustion and so on.

These require artificial intelligence control.

Xiao Feng may still be the first time, but if you shoot back and forth a few more times, you will have experience.

By November, the satellite was fully ready.

The model machine of the launch center has also been tested several times, and basically meets the requirements.

Jiang Cheng then set the first launch mission of the launch vehicle experiment on November 11, and if the experiment goes well, then after the vehicle is returned for maintenance, at the end of November, the first satellite of Fenghuo, "Fengxin-1", will be launched.

In 2020, Maple Group's aerospace dream officially set sail.
