"I'm sorry, we really don't have financing needs for the time being, and commercial aerospace can't make any money, I'm afraid you will lose money!"

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

"Not really."

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

“……”

Lin Ju has been annoyed by a number of investment groups for several days, but these capitals are all predators, and he has not yet reached the point where he can lose his face.

In particular, foreign capital is very interested in China's private aerospace industry, and the lowest investment has been given 10 million US dollars.

Of course, their purpose is not so noble, once they accept financing, they will definitely go public, and then speculate on the concept to cut the leeks of shareholders all over the world.

This is the same as when a grassroots Internet team could casually invest tens of millions of dollars, and people didn't care whether the company made money or not, and they didn't rely on this to make a profit.

What Capital Group is best at is to speculate on the company's concept and then make money through the stock price, which is much faster than the hard work of running the company to make profits.

But the consequence of this is that the company's life and death are not cared about, and the operation will be interfered with.

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

In addition to dealing with chores and changing the management structure during the few days of the plant upgrade, it was also up to the system engineers to decide how to choose system assistance.

Theoretically, a traditional spaceship is better, but、But the space shuttle is really cool!

"Lifting body, which means that the wing surface is small, the volume is small, the wing surface is lightweight, and the space utilization is very high."

"The second-level spacecraft is also very advanced! It does not need the escape tower to have its own escape ability, it can be reused, and only need to change the propulsion compartment each time...... It's not expensive compared to the whole launch project. ”

"But, but that's a space shuttle!"

The four system engineers could certainly discuss both options with confidence and work together in the evening for several days on end.

In the end, the answer they gave Lin Ju was: if the two schemes are technically complete, the space shuttle is slightly inferior in performance, but the potential is higher, and the two-stage multiplexing spacecraft is safer, but the upper limit is here.

In the engineers' research room, Lin Ju stared at the analysis drawings and blackboard handwritten notes scattered everywhere for a long time, pinched his chin and slowly spoke:

"As an aerospace company, prudence and safety are the first elements."

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

"So we chose the space shuttle."

"Uh...... Yes? ”

The four engineers were all swept away by Lin Ju's sudden turn, didn't they say steady?

"Look at what, we are open, of course it is common sense!"

Lin Ju is very natural, since the difficulty of the two is about the same, it is a space shuttle! He wants to go against the tide.

In the system panel, the institute added a second task - the first is the renovation project of Xinyuan-1.

[According to technical assistance, at least 5 astronauts or 2 astronauts and 3600 kg 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 task has been established, Guo Shen and the other three looked at each other and shrugged, and it was right to carry it out.

Lin Ju took out the rocket recovery technology of the system's assistance and mission rewards, and put the hard disk on the table:

"Guys, we only have 359 days, please use your potential!"

After 3 days, the engineers of the institute combed through the obtained technology.

3D rocket engine additive printing is a good thing, which can greatly shorten the manufacturing time of rocket engines, basically reaching the speed of the empty fork production engine of the old horse in later generations, and the manufacturing time of K120 can be cut in half.

The RX01 data bus is a software standard that supports the C-class rocket recovery technology, making the control of the rocket more refined and reliable.

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

It contains a fairly rich attitude database when the rocket is recovered, so that the automatic control system can predict the action of the rocket in advance, so that the attitude can be adjusted in time to avoid loss of control, and the overall reliability reaches 97%.

Finally, and most importantly, the technical indicators of the Space Shuttle, the H-1 type of internal code name.

The moment the technical data was interpreted, Guo Shen shouted that he had picked up the treasure.

The biggest trouble with the shuttle is not safety, but that it is too expensive.

The cost of a simple flight is not expensive, but the expensive thing is the external heat insulation tile and ceramic insulation board.

It sticks to the exterior of the shuttle like a brick, allowing it to travel through the atmosphere with a hundred-ton body without being burned.

Every flight mission has to be re-pasted, and the number is tens of thousands of yuan, and the cost of pasting heat insulation tiles alone can make the old beauty at its peak extremely painful.

Too many of them can also lead to safety hazards, and if a piece falls off, it may hit a certain part of the entire rocket, causing an accident.

The H1 space shuttle also has thermal insulation tiles, but its thermal insulation tiles are much more advanced.

Larger, lighter, and better-performing, the entire aircraft only used a few hundred pieces, which is a world away from the original space shuttle.

Moreover, 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 forward-thinking and bold, and the shape almost integrates the wing with the fuselage, so that the fuselage can also generate lift, making it look round as if there are no wings.

If you are a layman, you may suspect that this plane cannot fly at all.

The interior space has also changed compared to the traditional space shuttle, with better ergonomics and better maneuverability, and the first glance at it can give people the feeling of the future in a sci-fi blockbuster.

There is also a matching in-cabin spacesuit in the document, and the exterior design is also very simple, which is much lighter than that of today's countries.

After Lin Ju saw the renderings drawn by the computer, he couldn't wait to let it fly immediately, and even made a small model to be placed in the office as an ornament.

After being excited for a while, Lin Ju sounded the last question: Although this space shuttle is small, it is also a full 20 tons, what kind of rocket will be used to send it into the sky?

The system engineers certainly have their own solutions, and they come up with both.

"Boss, if we are more stable, we will directly use all the existing technology:

Develop a 3.5-meter diameter rocket body, install four K120 engines, and then 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 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 capacity will be 30 tons.

The advantage of this scheme is that the only technical difficulty is only 3.5 meters in diameter, but this diameter is not difficult, and the rest do not have any new technology, which is very reliable and extremely mature. ”

"What about the more radical ones?"

"This ...... I'm more inclined to be forward-looking. Anderov took over and pulled out a hand-drawn drawing of a rocket.

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

And this configuration can realize the recycling of the rocket stage, the structure is simple, and has the potential of CBC. ”
