I have a little black hole

He Cheng was also left speechless by this question. Plus, he was stared at with this kind of look, and he quickly explained with a voice: "No, boss! Our ship lab took this into account when it asked for it!

After the construction of the 1,000,000-ton mold forging hydraulic machine is completed, it can guarantee our company's high-end forging demand for at least five years, because even if we have now completed the final design draft of the second generation of spacecraft and started construction, that does not mean that we will be able to start the design and construction of the third generation spacecraft.

Not to mention the fact that we are still only just completing the initial overall design of this second generation spacecraft, and it will take at least a year before construction can really begin.

And the technology used on the second generation spacecraft has almost reached the technological limit of the company for a while now. Even if we can design the third generation spacecraft next, it can only be design, before the relevant technology has achieved a qualitative breakthrough, construction work can not know when to start.

In fact, the pressure demand of our current second-generation spacecraft for mold forging hydraulic machines is only 850,000 tons, which is enough. We have already had an advance consideration for the company to build a 1 million tons of mold forging hydraulic machines.

Even if we measure and technically upgrade the second-generation spacecraft at a later stage, it will never exceed the pressure demand level of 1 million tons. After all, there are limits to the technology involved.

Until we can break through to the technology of the third generation of spacecraft, we don't have that need on our side, so we don't know if other laboratories will have that need. ”

“What are you thinking? The company needs the highest pressure on the mold forging hydraulic machine in your spacecraft laboratory. If you don't need it on your side, the other laboratories will definitely not need it!" Confucius can't help laughing and throwing up the channel.

Everyone, including Lui Tiantang, was laughed at by his statement, but what he said was true. Even if the nuclear fusion reactor laboratory required the same exceptionally high structural strength for the main body, the company's existing 500,000-ton mold forging hydraulic machine would definitely be enough.

Other products of the company generally use 250,000 tons of die-forging hydraulic presses to specifically pursue performance, not to say that the better the pressure when forging, the more difficult and costly the subsequent processing of parts must also be taken into account.

So it's true that only the most demanding spacecraft laboratories on this side will have a particularly rapid increase in the pressure demand for mold forging hydraulic machines. There is no such particularly strong demand in other departments.

“It's not just our own second-generation spacecraft that needs this class of die-forging hydraulic presses, the military spacecraft research project that the company and the state are cooperating on, that also needs this tonnage of die-forging hydraulic presses!

After all, the military requirements for military-grade spacecraft are not the same as our own civilian spacecraft. Even our company's performance requirements for our spacecraft are very strict, but fundamentally, we still use civilian standards.

And for us, if we use military standards, the cost of building and using spacecraft would increase, and if we use military standards to design spacecraft, it would not be convenient for civilian use.

Space utilization and comfort of spacecraft manufactured using such design standards will vary greatly. Such standards are clearly not suitable for our company, especially its space tourism projects.

But for the military, the requirements for the strength and performance of the spacecraft are certainly very strict, and it is obviously not possible to use our own standards to make the body structure.

If the main structure of the ship is strong enough, it must be forged by a mold forging hydraulic machine with a higher tonnage, so there is demand on the side of this big country that the company is going to build in the future, and we will definitely be able to earn this investment back then! "He Xingyin throws a new explanation.

This statement is still acceptable to everyone in the conference room. The company has cooperated with the military in the development of various military equipment many times. Everyone understands the requirements and standards of the military. There is no problem with the reason why he is honest.

The requirements for military products and civilian products are absolutely different. Civilian products can be directly connected and used. But for military equipment, consideration must be given to earthquake resistance, shock resistance, overload resistance, electromagnetic radiation resistance, electron interference resistance, fire protection... and many other physical problems.

Let's compare it with the more familiar marine vessels. Civil ships and warships demand hulls differently.

Warships typically use thinner high-strength low-alloy steel, but the price of such steel is not only particularly high, but also quite difficult to weld, so civil ships typically use thicker sheets to ensure sufficient rigidity and reduce costs.

So the steel used in civilian ships and warships is different. The yield strength of ordinary civil ship steel is 200-300 MPa, and the destroyer class is 500-600, and the aircraft carrier submarine is even higher.

Likewise, if the spacecraft is replaced, even with the main structural materials used by the spacecraft, the military spacecraft must use stricter standards in forging strength, which is the only way to ensure that the spacecraft's performance meets military standards.

Believe everyone knows that the crew of a hundred thousand tons of oil tanker is just a few dozen people, while the navy's destroyer is just a few thousand tons, the crew is only a few hundred people, the merchant ship is generally not high speed, it is almost 14-17 knots, and the vast majority of battleships to the destroyer during World War II have been more than 30 knots.

For ships to sail faster, both the structural strength of the hull and the structural strength of the power system must be strong enough. Military-class spacecraft also have very high requirements for flight speed stability, all of which are equally dependent on more powerful manufacturing processes.

In terms of the manufacturing accuracy requirements of warships, the dimensional accuracy of warships is at least one order of magnitude higher than that of civilian ships. The rotor imbalance of warship engines is designed in accordance with aviation engine standards, and its allowable dosage accuracy is 4-5 orders of magnitude higher than that of civilian ships!

And warships have to assemble a lot of equipment in a very narrow space: machinery, weapons, control systems, radars, tube loss, circulation, communications, living equipment and so on. The difficulty is obvious.
