I ask you to build tractors, but you build rockets?

"Sorry, we really don't have financing needs at the moment, and commercial aerospace doesn't make much money. I'm afraid you will lose money!"

"Mr. Lin, aerospace is the future. What we at LDG Capital never care about is how much money we make, we just want to contribute more to the cause of human progress!"

"No need really."

"This is for the noble ideal of all mankind!"

"..."

Lin Ju has been annoyed by a group of investment groups for several days, but these capitals are all giants. He has not yet been able to show off his face and disappear.

Foreign capital, in particular, is very interested in China's private aerospace industry, with the lowest investment being US$10 million.

Of course, their purpose is not that noble. Once they receive financing, they will definitely go public, and then speculate on the concept to cut off the leeks of investors around the world.

This is just like the time when a start-up Internet team could invest tens of millions of dollars casually. They didn't care whether the company made money or not, and they didn't rely on it to make profits.

What Capital Group is best at is speculating on company concepts and then making money through stock prices, which is much faster than working hard to manage a company to earn profits.

But the consequence of this is that the company's life and death will not be cared about, and its operations will be interfered with. The Internet is okay, but physical companies are especially taboo about this, so Lin Ju will never be like this.

Even the shares distributed to employees only have dividend benefits and do not have decision-making power. The entire factory is firmly in the hands of Lin Ju.

In the few days of the factory upgrade, in addition to dealing with chores and changing the management structure, the system engineer decided how to choose system assistance.

In theory, traditional spaceships are better, but, but, the space shuttle is really cool!

"Lifting body, which means the airfoil is small, small in size, light in weight, and very efficient in space utilization."

"The secondary spacecraft is also very advanced! It does not need an escape tower to have its own escape capability, it can be reused, and only the propulsion module needs to be replaced each time... It is not expensive compared to the entire launch project."

"B-but that's a space shuttle!"

Four systems engineers could certainly discuss both options safely and spend several nights working on them together.

In the end, the answer they gave Lin Ju was: If both solutions were technically complete, the performance of the space shuttle would be slightly inferior, but the potential would be higher. The two-stage reusable spacecraft would be safer, but the upper limit would be here.

In the engineers' research room, Lin Ju stared at the analysis drawings and blackboard handwriting scattered everywhere and struggled for a while. He held his chin and spoke slowly:

"As an aerospace enterprise, prudence and safety are the top priorities."

Seeing that the boss finally made a decision, Guo Shen, who was also struggling, breathed a sigh of relief: "Yes, so plan one..."

"So we choose the shuttle."

"Uh...huh?"

The four engineers were all stunned by Lin Ju's sudden turn. Didn't they say they were steady?

"What are you looking at? We are cheating. Of course it is in line with common sense!"

Lin Ju took it for granted. Since the two are about the same difficulty, it would be the space shuttle! He decided to go against the trend.

In the system panel, the institute added a second task—the first one was the Xinyuan-1 renovation project.

[Based on technical assistance, at least 5 astronauts or 2 astronauts and 3,600 kilograms of scientific payload will be sent into low-Earth orbit and returned safely to complete a rocket recovery experiment. 】

[Current progress: 0%]

【Investment: 0】

Yes, the mission has been established. Guo Shen and the other three people looked at each other and shrugged, just execute it.

Lin Ju took out the system's assistance and the rocket recovery technology for mission rewards, and placed the hard drive on the table:

"Everyone, we only have 359 days, please realize your potential!"

Three days later, engineers from the institute reviewed the obtained technology.

3D rocket engine additive printing is a good thing. It can greatly shorten the manufacturing time of rocket engines. It has basically reached the speed of the air-fork production engine of later generations, and the manufacturing time of K120 can be cut in half.

The RX01 data bus is a software standard supporting C-class rocket recovery technology, making rocket control more precise and reliable.

C-class rocket technology refers to the recovery technology of the first stage of a 5-meter-diameter rocket, which uses its own tripod and vertical landing.

It contains a fairly rich attitude database during rocket recovery, which enables the automatic control system to predict the rocket's movements in advance and adjust the attitude in time to avoid loss of control. The overall reliability reaches 97%.

Finally, and the most important is the technical specification of the internally coded H-1 space shuttle.

The moment the technical information was interpreted, Guo Shen said he had found a treasure.

The biggest problem with the space shuttle is not its safety, but its high price.

The cost of a simple one-time launch is not expensive, but the expensive ones are the external insulation tiles and ceramic insulation panels.

It is attached to the exterior of the space shuttle like bricks, allowing the latter to travel through the atmosphere with a 100-ton body without being burned.

Every mission has to be re-attached, and the amount is tens of thousands of dollars. The cost of insulating tiles alone would make even the United States in its peak period extremely heartbroken.

Too many can also cause safety hazards. If one piece falls off, it may hit a certain part of the entire rocket, causing an accident.

The H1 space shuttle also has insulation tiles, but its insulation tiles are too advanced.

It is larger in area, lighter in weight, and has better performance. The entire aircraft only cost a few hundred yuan. It is completely different from the original space shuttle.

And according to the design, it can be reused at least three times, and the cost of each launch can be reduced a lot.

The overall design is also very advanced and bold. In appearance, the wings and the fuselage are almost integrated into one, allowing the fuselage to generate lift, making it look round and round as if it has no wings.

If you are an outsider, you may suspect that this plane cannot fly at all.

The internal space has also changed compared with the traditional space shuttle, with better ergonomics and better maneuverability. The first sight of it gives people the feeling of the future in a science fiction blockbuster.

There is also a matching in-cabin spacesuit in the information, and the exterior design is also very simple, much lighter than those in other countries today.

After seeing the computer renderings, Lin Ju wanted to make it fly right away. He even made a small model to put in the office as a decoration.

After being excited for a while, Lin Ju asked his last question: Although this space shuttle is small, it still weighs 20 tons. What rocket was used to send it to the sky?

Systems engineers certainly have their own solutions, and they came up with two.

"Boss, if you are more prudent, we will just use all existing technologies:

Develop a 3.5-meter-diameter rocket body, install four K120 engines, and bundle two existing 2.5-meter-diameter boosters, each equipped with a K120 engine, with a take-off thrust of 732 tons, a load factor of about 3%, and a low-Earth orbit transport capacity of 21.5 tons, just enough for the space shuttle.

If four are bundled, the take-off thrust will be 976 tons and the low-Earth orbit transport capacity will be 30 tons.

The advantage of this plan is that the only technical difficulty is the 3.5-meter-diameter rocket body, but this diameter is not difficult. There are no other new technologies. It is very reliable and extremely mature. "

"What about the more radical ones?"

"This... I prefer a long-term plan." Androv took over and took out a hand-drawn rocket drawing.

"Develop a new engine based on the K120 to increase the thrust to about 150 tons; develop a 5-meter-diameter rocket body equipped with 7 new engines, with a take-off thrust of 1,050 tons and a progress orbit carrying capacity of about 31 tons.

Moreover, this configuration can realize the recycling of the rocket stage, has a simple structure and has CBC potential. "

The contract has been signed, so now it’s time... Readers, please give Mengxin a monthly pass
