MTL - Comeback 1992-Chapter 1221 Dijiang 300
Chapter 1221 Dijiang 300
Before school officially started, Han Xuan had already moved out, or was kicked out by Tang Yan. Tang Yan was very angry about her son's behavior of not wanting a mother after having a wife.
It is simply unreasonable.
Get kicked out early, so as not to be upset.
Han Yufei always felt that Auntie was happy in her heart!
When Xingchen University started military training for freshmen, Han Songlin was standing in the control room of Xinghai Exploration Company in Jianzhou to watch the rocket engine experiment.
Dijiang 300 rocket engine.
This is a rocket engine with a maximum thrust of 300 tons, and it is also the rocket engine with the largest thrust in Huaguo today.
It will be used as the main engine for future space station launches.
In order to develop the Dijiang 300 rocket engine, countless scientific researchers across the country are working on it.
Let’s talk about the material of the engine.
The position of the nozzle requires high temperature resistant materials, and the Materials Research Institute of Xingchen Institute organized personnel to carry out scientific research.
The laboratory has been completed, and it has to be produced in industry.
Many laboratory technologies have not been applied to industrial production. There is a problem with the transformation mechanism of achievements, and there is also a cost problem.
The cost is too high, and the market cannot accept it.
For most of the results, with the advancement of technology, the cost will be directly reduced.
After the cost is reduced, the public will be able to enjoy the convenience brought by this technological advancement.
"Now, can this engine be officially applied?"
Han Songlin was concerned about one thing, whether the engine could work or not.
The rocket bundled with five Dijiang 300 rocket engines can have a huge thrust of 1,500 tons.
What if the engine is being added?
Directly use eight Dijiang 300 rocket engines, then the thrust will reach 2400 tons.
Of course, the rocket does not mean that the more engines, the better, and some strict design considerations have to be carried out.
If there are too many rocket engines, there will be problems such as coupled vibration, a decrease in the thrust-to-weight ratio of the rocket, and a decrease in system reliability.
Therefore, the number of rocket first-stage engines is usually controlled within 10.
But on the other side of the Pacific Ocean last year, a private rocket company released a picture of a Falcon Heavy rocket.
Also announced some situations, 27 Merlin 1D engines will be used.
The thrust will reach an astonishing 2,280 tons, making it the rocket with the largest carrying capacity of active rockets in the world.
The low-earth orbit is 63.8 tons, and the synchronous orbit is 26.7 tons.
Compared to the 120-ton low-Earth orbit carrying capacity of the Saturn 5 rocket back then, it is still a lot worse, but this rocket can be regarded as quite ruthless.
The other side of the Pacific Ocean has now lost the manufacturing capacity of the Saturn 5 rocket, and even the blueprint has been lost in rumors.
But I have to say one thing, in terms of strength in the aerospace field, the other side of the Pacific Ocean is still quite strong.
If it hadn't been for choosing the wrong technical route and embarking on the path of the space shuttle, I don't know what level the rocket technology on the other side of the Pacific will reach.
Although the Falcon Heavy rocket on the other side has not yet conducted a test launch, the media hype has already begun.
Since 2013, it has been said that it will be launched, but tickets are skipped again and again.
According to the information obtained from Star Sea Exploration, the Falcon Heavy rocket, which has bounced tickets many times, is really coming.
The other side brought out such a powerful thing, Xinghai Exploration also had to respond.
Dijiang 300 rocket engine is the strongest proof.
The success of the Dijiang 300 rocket engine means that the next generation of heavy rockets will have a strong power source guarantee.
"The new generation of rockets and rockets has been completed, and we plan to launch them on the South China Sea Island in December."
This kind of experimental rocket launch, the things that are brought into space are usually cement blocks or the like.
But this time, Han Songlin decided to bring something different.
car?
Bring more expensive things, forget it.
no need.
Experimental launch, to be honest, the possibility of failure is quite high.
Han Songlin: "Okay, I will go to watch it live."
After returning to Rongcheng, Han Songlin sat in the office and looked at the funds spent in exploring Xinghai over the years.
More than 30 billion yuan was spent just to study rocket engines.
This does not include rocket development.
Fortunately, Star Sea Exploration can also make some money.
In the international space launch market, Xinghai Exploration has received a lot of orders.
Xinghai Exploration is on the space launch, the price is quite low, and the accident rate is also low.
The decrease in the accident rate is not only due to the rigorous scientific attitude of Xinghai exploration engineers, but also the continuous progress in material technology.
What to do, the material is really critical, it can be said to be the key to success or failure.
A lot of money has been invested in material research and development over the years.
"Allocate another 10 billion research and development funds to Xinghai Exploration."
Zhu Xiangping hesitated for a moment. There is nothing strange about the additional research and development funds.
But Xinghai Exploration belongs to the kind of big family that can't create profits, it only consumes money but doesn't make money.
As for the launch orders that Xinghai Exploration received, the profit is indeed quite high.
If you succeed, you can earn tens of millions or hundreds of millions of dollars in one order.
Can it fail?
In order to reduce the risk, Xinghai Exploration also bought insurance.
The insurance premium is quite high anyway.
Few insurance companies dare to take orders.
"Boss, the money comes from the reserve fund, or..."
In other words, squeeze some funds out of other projects.
Xinghai Group currently holds more than 400 billion cash in hand.
The money is used as a reserve fund to deal with some sudden use of money.
"Out of reserves."
Zhu Xiangping pursed her lips and said with a smile: "You have to talk to Mr. Zheng personally."
In the Xinghai Group, no one knows that Zheng Lin and Mr. Zheng are becoming more and more like an iron rooster.
It is difficult to apply for some money outside the plan.
Han Songlin: "OK, I'll talk to Zheng Lin."
Han Songlin naturally knows why Zheng Lin is like an "iron rooster".
Zheng Lin This is to prevent everyone from spending money indiscriminately.
Especially guard against Han Songlin.
Han Songlin is really too extravagant. According to Han Songlin's way of spending, no amount of money will be enough.
Fortunately, the profitability of the companies under the Xinghai Group is really super strong, otherwise they would not be able to support the Xinghai Group to spend money.
Xinghai Group spends more than one trillion yuan on research and development every year.
Yes, trillions.
accounts for forty percent of the national research and development (R&D) funding.
The highest proportion of Xinghai Group reached 60%, but in recent years, the proportion has dropped relatively quickly.
The main reason is that other companies have stepped up their research and development investment.
There is no way not to strengthen the strength, if you don't strengthen it, there will be no business for them in the future.
In terms of scientific research investment, the other side of the Pacific Ocean invested 496 billion U.S. dollars last year.
There is still a certain gap with its investment, but according to the current growth rate, in 2019, it will surpass the other side of the Pacific Ocean and become the country with the highest investment in research and experimental development (R&D) in the world. (In fact, it is predicted that in 2022, the investment in scientific research will surpass.)
