I Have a Little Black Hole

He Chengxin was also speechless when asked by this question. In addition, he was stared at by everyone with this kind of eyes, and he quickly explained: No boss! Our spaceship laboratory thought about this when we put forward this demand. That's it!

After the completion of the construction of the 1 million-ton hydraulic die forging press, it can at least guarantee the high-end forging needs of our company within 5 years, because even if we have completed the final design draft of the second-generation spacecraft, construction has begun. , that does not mean that we have the ability to start the design and construction of the third-generation spacecraft.

Not to mention that we have only just completed the preliminary overall design of this second-generation spacecraft, and it will take at least a year before the actual construction can begin.

And the related technologies used on the second-generation spacecraft are already approaching the company's technical upper limit for a while now. Before a qualitative breakthrough has been made in the related technologies, we will be able to carry out the third-generation spacecraft. The design work is only design, and the construction work does not know when it will start.

In fact, the pressure demand of our current second-generation spacecraft for the die forging hydraulic press is only 850,000 tons, which is enough for our company to build a 1 million-ton hydraulic die forging press. considered.

Even if we upgrade the size and technology of the second-generation spacecraft in the later stage, it will never exceed the pressure demand level of 1 million tons. After all, the related technology has limits.

Before we break through to the technology of the third-generation spacecraft, there is no such demand on our side, and we just don't know whether other laboratories will have such a need.

What are you thinking! Your spaceship laboratory has the highest pressure requirement on the hydraulic press for die forging in the whole company. As long as you don't need it on your side, then other laboratories definitely don't need it! Kong Yuxiao couldn't help laughing Tucao loudly.

Everyone, including Lei Tiantang, was amused by his statement, but what he said was also true. Even in the nuclear fusion reactor laboratory, which requires the same high strength of the main structure, the company's existing 500,000 tons A high-grade die forging hydraulic press is absolutely sufficient.

The company's other products generally use 250,000-ton hydraulic presses for special performance. It does not mean that the pressure is better when forging. You also have to consider the difficulty and cost of subsequent processing of parts. of.

Therefore, it is true that only the spaceship laboratory with the highest performance requirements will the pressure demand for die forging hydraulic presses grow particularly fast, and other departments do not have such a particularly strong demand.

That's not only our company's own second-generation spacecraft that needs this level of die forging hydraulic press, the military spacecraft research project that the company cooperates with the country also needs this tonnage of die forging hydraulic press!

After all, the military's requirements for military-grade spacecraft are different from our own civilian spacecraft. Even our company has very strict performance requirements for its own spacecraft, but fundamentally we still use the Civil Standard.

For us, if the military standard is adopted, the manufacturing cost and the cost of using the spacecraft will increase, and if we design the spacecraft according to the military standard, such a spacecraft will be inconvenient for civilian use.

Because the space utilization and comfort of the spacecraft manufactured with such design standards will be very different, such standards are obviously not suitable for our company, especially the company's space tourism projects.

But for the military, the requirements for the strength and performance of the spacecraft must be very strict, and it is obviously impossible to use our own standards to manufacture the main structure.

If the main structure of the spacecraft is to be strong enough, it must be forged by a hydraulic press with a higher tonnage. Therefore, the big country that the company plans to build in the future is also in demand.

At that time, we will definitely be able to earn back this investment! He Chengxin throws out a new explanation.

Everyone in the conference room can accept his statement. The company has cooperated with the military to develop various military equipment many times. Everyone knows the requirements and standards of the military. He Chengxin's reason There is no problem.

The requirements for military products and civilian products are absolutely different, and civilian products can be directly connected and used. But for military equipment, it is necessary to consider many physical problems such as shock resistance, shock resistance, overload resistance, electromagnetic radiation resistance, electronic interference resistance, fire prevention...etc.

Let's take the more familiar marine ships for comparison. Civilian ships and warships have very different hull requirements.

Warships generally use relatively thin high-strength low-alloy steel, but the price of this steel is not only particularly high, but also difficult to weld, so civilian ships generally use thicker plates to ensure sufficient rigidity and reduce costs.

Therefore, the steel used by civilian ships and warships is different. The yield strength of steel for ordinary civilian ships is 200-300 MPa, while the destroyer class will reach 500-600, and the aircraft carrier submarine will be higher.

Similarly, if it is replaced by a spacecraft, even if the main structural material of the spacecraft is the same, the military spacecraft must use stricter standards for forging strength. Only in this way can the performance of the spacecraft meet the military standards.

I believe everyone knows that an oil tanker with hundreds of thousands of tons has only a few dozen crew members, while a Navy destroyer is less than 10,000 tons, and the crew is only a few hundred people. The speed of merchant ships is generally not high, about 14-17 knots. , and during World War II, the vast majority of battleships to destroyers had a speed of more than 30 knots.

In order to make the boat sail faster, both the structural strength of the hull and the structural strength of the power system must be strong enough. And military-grade spacecraft also have particularly high requirements for flight speed and stability, which are also inseparable from more powerful manufacturing processes.

In terms of the manufacturing accuracy requirements of warships, the dimensional accuracy of warships is at least an order of magnitude higher than that of civilian ships. The rotor imbalance of warship engines is designed according to the standard of aero-engine, and its allowable amount accuracy is 4-5 orders of magnitude higher than that of civilian ships!

Moreover, the warship has to integrate a large number of equipment in a very narrow space: machinery, weapons, control systems, radar, damage control, circulation, communication, living equipment and many other problems, the difficulty is obvious.
