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

Chen Jun expressed this idea tactfully, and Lin Ju said he fully understood.

I just want to spend less money and act like a big B.

This is simple, just paint the already fourth-generation Xinyuan-1B first-stage rocket, install a new second-stage rocket, and launch any gadget.

The price is also cheap. As long as the recycling is successful, the cost will be less than 5 million, so the quote is 10 million.

This price is completely within Chen Jun's acceptable range. 10 million for a rocket is regarded as a public investment. It is simply too cheap.

The two parties hit it off immediately, and with the production capacity of Xinyuan No. 1B, it can be delivered in one month, and it can be launched before the Chinese New Year, which is also a blessing to the group's senior management.

The cooperation was simply finalized, but Lin Ju did not see the guests off and Chen Jun was not in a hurry to leave.

The latter wanted to see more about Xinyuan Aerospace and understand the operation of private aerospace.

Lin Ju was thinking about how to continue taking money out of Nanfang Auto's pocket.

Nowadays, Southern Auto is a great company. It has sales volume, technology, capital and connections.

If they are allowed to purchase Xinyuan's BMS and join the smart driving plan in the future, they can afford research funds and don't have to worry about opening up the market.

I spent half a day wandering around insensitive areas with Chen Jun. The latter kept admiring all the novel things.

Lin Ju pretended to be casual and said:

"Now the country seems to be promoting new energy vehicles, and Southern Motor should be doing the same."

"Yes, but now is not the time." Chen Jun looked uninterested:

"Both the market environment and technology are immature now. Have you seen those braggarts? They are all cheating on subsidies. They produce dozens of cars and then work with dealers to forge tens of thousands of them. They can just get 700 to 800 million. subsidies are obtained.

There are no real technical people. We are doing research. Technical people have said that electric vehicles are a new standard system. It is better to think about hybrid vehicles now. "

Chen Jun was probably quite happy. He told Lin Ju several examples of insurance fraud and subsidy fraud in the industry. Manufacturers in the industry seemed fishy at first sight, but the amazing thing was that these loophole-filled operations actually succeeded.

It was also the first time that Lin Ju learned so many secrets and gradually came up with his own ideas.

The battery technology of BYD and Zhude does not yet have the same performance as later, and there is no mature BMS system on the market. New energy vehicles are still in the growth stage.

Although Chen Jun said that it was not the right time in many aspects, in fact the biggest problem is the performance of new energy vehicles and the intelligent driving that future generations will rely on.

Solving these two problems, new energy vehicles will still unstoppably encroach on traditional market shares.

Moreover, there is a first-mover advantage in entering the market now. In the era of chaos in a few years, especially when a number of Internet companies have withdrawn their capital, tram technology has advanced so rapidly that it will be difficult for traditional manufacturers to catch up.

But now Lin Ju keeps these things in his heart. He has to wait for Xinyuan's BMS to have results before discussing cooperation. Now he first builds relationships.

+1 for potential partners.

…

From the end of November to the whole of December, Xinyuan finally calmed down in the eyes of the outside world, and there was no big news anymore.

The only launch disclosed to the outside world has not yet started. Xinyuan purchased a tugboat and converted it into a sea take-off and landing platform. Now it is rushing to the South China Sea to prepare for a sea rocket recovery test.

But in fact, Xinyuan Aerospace was extremely busy during this period.

The R\u0026D department is sorting out the system technologies obtained one by one, adjusting them to specific projects, and modifying the rocket configuration.

In addition, it will recruit 100 more employees and use upgrade cards to upgrade the skills of those with potential.

Due to the acquisition of a lot of new technologies, the rocket Xinyuan 2 prepared for the H1 space shuttle was basically overturned.

The new parameters are as follows:

The entire arrow has a diameter of 6 meters and a height of 75 meters. It adopts a two-stage rocket design.

The first level will be equipped with 7 220-ton liquid oxygen and methane engines, 6 in the outer ring and 1 in the center, with a ground thrust of 1,540 tons. The second level will be equipped with a 50-ton liquid oxygen and liquid hydrogen engine, with a low-Earth orbit carrying capacity of up to 45 tons. , and the first level will be designed to be recyclable.

The methane engine series starts with M and focuses on low cost. The M220 is simplified from the system's 300-ton staged combustion liquid oxygen methane engine, reducing the weight and volume, allowing it to fit seven units into a 6-meter-diameter rocket body. .

The reason why we chose a methane engine instead of a kerosene engine is because the staged combustion high-thrust methane engine is technically simpler and faster to produce than the K series full-flow kerosene engine.

The institute decided to complete the research and development in only 4 months, which is not a lack of confidence.

Xinyuan-2 is expected to be recyclable thirty times. After five reuses, the cost of each launch will be 30% of that of a one-time launch, requiring only 130 million yuan. The average launch cost per kilogram is less than 4,000 yuan.

Even including measurement and control, transshipment and other expenses, it will not exceed 4,200 yuan.

And the biggest cost is the two-stage hydrogen-oxygen rocket engine. The hydrogen-oxygen engine and liquid hydrogen fuel are really expensive.

Xinyuan-3 was changed into a giant rocket:

The first stage has a diameter of 11 meters, the second and third stages are also 11 meters in diameter, and the height is 116 meters. It adopts a three-stage rocket design.

There are 19 380-ton liquid oxygen and kerosene rocket engines installed on the first stage, arranged in a 12+6+1 layout from the outer ring inward. Four 240-ton liquid oxygen and liquid hydrogen engines H240 are installed on the second stage, with a total ground thrust of 7,300 tons. , the low-Earth orbit carrying capacity is 270 tons, the lunar orbit carrying capacity is 130 tons, and the Mars orbit carrying capacity is 60 tons.

This is a rocket prepared for landing on the moon. It can also be recycled 20 times, but the average launch cost has still soared to a full 400 million yuan. The three-stage rocket will be replaced by the H2 space shuttle when landing on the moon.

There is also a draft of the moon landing plan. The H2 with a maximum take-off weight of 100 tons has an empty weight of only 40 tons. The cargo compartment of the moon landing version will be added with a living module and a lunar lander. The total weight will be controlled at about 95 tons and can carry 7 astronauts.

There is a cost for such a heavy space shuttle to fly completely and return to the earth. The traditional engine consumes too much fuel and is not feasible. It is expected to be equipped with a 10-ton nuclear thermal rocket engine with a unit price of more than 300 million yuan, which is very fuel-saving.

It can only be said that engineers with money and skills have begun to let themselves go, but Lin Ju still approved it, because the research plans of the latter two have a two-year deadline and have time to adjust.

The other is the turbofan part removed from the 90KN combined power engine. After evaluation, it is believed that two modifications can be developed.

The best modification is to be used as a fighter or bomber engine, because this turbofan engine, tentatively named XW-9, according to the system introduction, can propel the aircraft to an altitude of 33,000 meters, with a Mach number of 3.4.

After being taken out separately and made into a small-bypass-ratio aviation engine, the thrust is as high as 13.9 tons in the afterburner state, the thrust-to-weight ratio is 10.6, and it can last for 40 minutes. Fighters with a take-off weight of less than 40 tons can easily fly to Mach 3 when used.

The second is to increase the bypass ratio and cut off the afterburner at the expense of reducing the maximum speed. As a technology or transport aircraft engine, a single unit has a thrust of 15 tons and a fuel consumption rate of 0.52, which is relatively fuel-efficient in the same class.

The manufacturing cost of both engines is between 15 million and 25 million each. The former is about 5 million US dollars and the latter is less than 20 million US dollars for engines of the same level. Obviously, the profits are extremely high.

The BMS battery management system has also been modified and the original plan has been issued. The research team is selecting the automotive platform and choosing an opportunity for testing.
