Chen Jun euphemistically expressed this idea, and Lin Ju expressed complete understanding.

I just want to spend less money to pretend to be a big B.

This is simple, paint the Xinyuan-1 B-1 rocket, which is already a four-handed rocket, install the new second-stage rocket, and launch a gadget casually.

The price is also cheap, as long as the recycling is successful, the cost is less than 5 million, and the quotation is 10 million.

This price is completely within Chen Jun's acceptable range, 10 million to buy a rocket, just as the publicity and distribution, it is simply too cheap.

The two sides hit it off, and the production capacity of Xinyuan No. 1B can be delivered in one month, and it can be launched before the Chinese New Year, which can be regarded as a joy for the group's senior management.

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

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

Lin Ju was thinking about how to continue to take money out of the pocket of the southern car.

Now the southern car cow, there is sales, technology, capital and connections.

If they are allowed to buy Xinyuan's BMS and join the intelligent driving plan in the future, they can bear the research funds without worrying about opening up the market.

Spend half a day walking around the insensitive area with Chen Jun, who watched all kinds of novelties and constantly admired.

Lin Ju pretended to be casual and said:

"Now the country seems to be promoting new energy vehicles, and Southern Automobile should also do it."

"Yes, but now is not the time." Chen Jun seemed to be in a lack of interest:

"Now that neither the market environment nor the technology is mature, do you see those bragging? They are all cheating subsidies, and when they produce dozens of cars, they will cooperate with dealers to forge tens of thousands of transactions, and they will get a subsidy of seven or eight billion yuan.

There is no real technology, we are researching, people in technology have said that electric vehicles are a new standard system, and it is better to think about hybrid vehicles now. ”

Chen Jun may be more happy, and told Lin Ju several examples of fraud and subsidies in the industry now, and the manufacturers in the industry are tired at a glance, but the magic is that these operations full of loopholes are really successful.

Lin Ju also learned so many secrets for the first time, and gradually had his own ideas.

The battery technology of BIATTI and MAD has not yet had the performance of the latter, and there is no mature BMS system on the market, and the new energy vehicles are still in the growth period.

Although Chen Jun said that many aspects are not timely, in fact, the biggest problem is the performance of new energy vehicles, as well as the intelligent driving that future generations rely on.

To solve these two problems, new energy vehicles will still inexorably encroach on the traditional market share.

And now there is a first-mover advantage in the entry, and in a few years later, in the era of the demons dancing, especially a number of Internet companies with capital down, tram technology is advancing rapidly, and traditional manufacturers are struggling to catch up.

But now Lin Ju first pressed these in his heart, he had to wait for Xinyuan's BMS to have results before he could talk about cooperation, and now he will first wrap up the relationship.

+1 for potential partners.

……

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

The only public launch has not yet begun, Xinyuan purchased a tugboat to convert into a sea take-off and landing platform, and is only now rushing to the South China Sea to prepare for a sea rocket recovery test.

But in fact, during this time, Xinyuan Aerospace was busy flying.

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

In addition, we will recruit 100 more employees and use upgrade cards to upgrade potential employees.

Thanks to a large number of new technologies, the rocket Xinyuan-2 prepared for the H1 space shuttle was basically overturned and restarted.

The new parameters are as follows:

The total arrow has a diameter of 6 meters and a height of 75 meters, and is designed as a two-stage rocket.

The first stage will be equipped with seven 220-ton liquid oxygen methane engines with six in the outer ring and one in the center with a ground thrust of 1,540 tons, and the second stage 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 stage will be designed to be recyclable.

The M220 is a simplified version of the system's 300-ton staged combustion liquid oxygen methane engine, reducing weight and volume, allowing it to fit seven into a 6-meter diameter rocket body.

The reason why the methane machine is chosen over the kerosene machine is because the staged combustion high-thrust methane machine is simpler and faster to produce than the K series full-flow kerosene machine.

The research institute decided to complete the research and development in only 4 months, which can be described as a lack of confidence.

Xinyuan-2 is expected to be recycled 30 times, and the cost of each launch after five reuses will be 30% of the one-time launch, only 130 million yuan, with an average launch cost of less than 4,000 yuan per kilogram.

Even if the cost of measurement and control, transshipment and other expenses is included, it will not exceed 4,200 yuan.

And the biggest cost of this is that the two-stage hydrogen-oxygen rocket engine, the hydrogen-oxygen engine and liquid hydrogen fuel are really expensive.

Xinyuan-3 was changed to a giant rocket:

The diameter of the first stage is 11 meters, the diameter of the second and third stages is also 11 meters, the height is 116 meters, and the three-stage rocket design is adopted.

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

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

The lunar landing plan has also been drafted, the H2 with a maximum take-off weight of 100 tons has an empty weight of only 40 tons, and the cargo compartment of the lunar landing version should be equipped with a living module and a lunar lander, with a total weight of about 95 tons, which can carry 7 astronauts.

There is also a price for such a heavy space shuttle to fly over and return to Earth in its entirety, and it is expected to install a 10-ton nuclear thermal rocket engine with a unit price of more than 300 million yuan, which is very fuel-efficient.

It can only be said that the engineers with money and technology have also begun to let themselves go, but Lin Ju still approves it, because the research plans of the latter two are limited to two years, and there is time to adjust.

In addition, the turbofan part that was removed from the 90KN combined power engine was evaluated and it was believed that two modifications could be developed.

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

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

The second is to increase the bypass ratio, at the cost of reducing the maximum speed, cut off the afterburner, as a technology or transport aircraft engine, a single thrust of 15 tons, fuel consumption rate of 0.52, in the same class is more fuel-efficient.

Both engines cost 15 million to 25 million units to manufacture, while the price of the engine of the same class is about $5 million, and the latter is under $20 million, which is obviously extremely profitable.

The original scheme of the BMS battery management system has also been revised, and the research team is selecting the automotive platform for testing at the right time.
