Chapter 1539

No wonder Mr. Tian Changmao was so surprised. Zhuang Jianye was really dressed in casual clothes. There were more than ten rocket engines behind him. That's all. The key is that Mr. Tian has never seen the style of those rocket engines.

The shiny pipeline, even the outer wall of the tail nozzle of the bell mouth, is also shiny and emits metallic luster.

That's all. The key is that there is a small nozzle next to the tail nozzle, which looks a little strange but integrated.

Because the structure of the whole rocket engine is very compact, not to mention, the key is that it should be very light in weight, because more than a dozen are combined and easily lifted to the other end of the plant by a 20 ton gantry crane. Obviously, its lightness has reached an amazing level.

You should know that the same number of rocket engines produced by other long-term Aerospace Manufacturers in China need at least 50 ton gantry crane to barely lift.

However, this is not the focus of Mr. Tian's attention. The main reason for his surprise is that Xikang factory produces the rocket engine itself.

You should know that although China Tengfei is involved in aerospace business, its business scope is limited to the body and fuel tank of some launch vehicles and long-range missiles. Even if it undertakes the project of developing solid launch vehicles, the core solid rocket motor and overall control system are provided by other aerospace system manufacturers.

This is not to say that China Tengfei doesn't want to do this business, but something related to the army. The threshold of access is very high. With the details of China Tengfei, there are bad hardware that can't meet the standard. Because of this, up to now, the domestic rocket engines are still controlled by several large factories in the system.

This is also an important reason why Zhuang Jianye will abandon China's booming aerospace business and start a new business to establish ztm-nb space exploration company.

If you want to do it or not, just get rid of the burden and do it yourself.

The entry threshold involving the army is not high, so ztm-nb space exploration company is simply cut off from the army business and enter the head office as a purely civilian Aerospace start-up company.

Yes, of course. After all, with the support of China's take-off, the purely civilian Aerospace access threshold is still good to cross. However, in addition to crossing this minimum threshold, the industry is not optimistic about ztm-nb space exploration's business model of the whole industry chain.

You should know that the technical difficulty of aerospace is not much lower than that of aviation, especially several key components, which are the optimal solutions accumulated by mankind in the past half a century.

If China wants to take off on its own, it is ready to finish the road of those domestic aerospace giants for more than half a century. It is a joke anyway.

Moreover, the input-output ratio of aerospace is notoriously low. More than 90% of the weight of a launch vehicle is fuel and oxidant, and less than 10% is used for payload. It can be said that every cubic centimeter on the spacecraft really exudes the smell of money.

Because of this, the general space launch can earn money as long as it can ensure the balance of revenue and expenditure. If the spacecraft can play the design level, it will make a lot of money. As for the cost of launch vehicle R & D, manufacturing and launch, it is a confused account and can't be calculated at all.

If not, why is the aerospace industry operated by the national team? There is no way. Only the country and a powerful country can play such a national important weapon. It is estimated that if ordinary enterprises make a sounding rocket, it will be quickly dragged down by huge investment, let alone normal Aerospace Launch.

When Kezhuang Jianye founded ztm-nb space exploration company, he issued a plan to realize the launch of the first carrier rocket within 5 years, make a profit within 8 half a year, and reduce the current domestic space launch cost by 50% within 10 years.

It's very heroic to say this, but the industry scoffs at it. You know, the domestic aerospace production cost is the lowest in the world. On this basis, it's almost impossible to reduce it by 50%. You know, which aerospace products are not piled up with money, Ztm-nb space exploration company can maintain the existing cost without rising. Do you want to reduce it?

Either Zhuang Jianye dreamed, or Zhuang Jianye made a model, or there is no possibility at all.

It is precisely because ztm-nb space exploration company is not optimistic about all kinds of things. During the preparation of Xikang plant, a group of old leaders and authoritative experts in the aerospace field, including Tian Changmao, did not pay much attention.

Later, it was said that Xikang factory had chaotic management and loose organization, and Tian Changmao and others didn't care more.

However, just when Tian Changmao and others were about to forget Xikang plant, the live broadcast of CCTV not only brought it back into people's sight, but also found that Xikang plant actually got out the most critical rocket engine of the launch vehicle.

How many years?

It seems that Xikang factory will build its own rocket engine in about three years?

Apart from others, this speed alone is enough to shock Tian Changmao.

"Grandpa ~ ~ grandpa ~ ~ grandpa?"

When Tian Changmao was stunned, Tian Lu suddenly shouted a few times, bringing Tian Changmao's thoughts back to reality: "I think Zhuang Jianye's ztm-nb space exploration company still has something. After all, not every aerospace enterprise has the ability to produce rocket engines. Even if it is only a low-end engine for small launch vehicles, it is also a great breakthrough."

After listening to his grandson's words, Tian Changmao was stunned. He narrowed his eyes and looked carefully at the rocket engine being hoisted behind Zhuang Jianye. In terms of size and weight, it was really not a powerful thing, so he nodded: "Indeed, it is a miracle that a small thrust rocket engine can be produced within three years. It can be seen that Zhuang Jianye is still very capable, but the small thrust is simple, and it is difficult to go up. After all, the larger the thrust of the rocket engine is, the harder it is. Now, except Russia and the United States, no one in the world can produce a large thrust rocket engine of more than 300 tons, even 5 There are only four or five countries in the world with a capacity of 0 tons. They are all countries and Zhuang Jianye's enterprises... "

Mr. Tian didn't say any more, but shook his head slightly. It is obvious that he is still not optimistic about the follow-up development of ztm-nb space exploration company.

However, when Mr. Tian sighed and was ready to say something, Zhuang Jianye had completely become a live show of Zhuang Jianye's monologue. After making a general introduction to Xikang factory, Zhuang Jianye suddenly waved to a forklift master not far away. The forklift master immediately drove the loaded rocket engine together with the forklift.

Zhuang Jianye pointed to the nearly 3M high rocket engine that had just been boxed, photographed the highly glossy tail nozzle below, smiled and said to the camera: "This is the first practical rocket engine developed by ztm-nb space exploration company, dpz-2d liquid oxygen kerosene rocket engine, with a total weight of 547 kg, a sea-level thrust of 66.5 tons, a sea-level specific impulse of 282 seconds and a thrust weight ratio of 150..."

Before Zhuang Jianye finished his words, old man Tian Teng in front of the TV bounced up from the sofa. A pair of old eyes stared at the dpz-2d liquid oxygen kerosene rocket engine in the TV and said in an incredible whisper: "liquid oxygen kerosene... 66.5 tons of thrust, how is this possible, how is it possible..."
