I have a little black hole

As with all kinds of ships navigating at sea, it is more important to have a strong enough structure for a ship to be able to navigate safely at sea, even in the face of severe weather and sea conditions such as tornadoes, in addition to the fact that the ship's tonnage is large enough.

And to do that, it would be very demanding on the very foundation of the ship —— the keel. Contemporary boat keel refers to a longitudinal member connecting the bow and stern columns in the middle of the base of the hull, which is located at the bottom of the boat.

On the top of the keel are transverse ribs reinforced. Forward and aft, the keel bypasses the columns. The keel is usually the first part of the hull to be built.

The main role of the ship's keel is load bearing, which is the most important load bearing structure of the ship, especially small ships, which bears the longitudinal bending torque of the hull and ensures the strength of the ship's structure.

Together with the support of the various load-bearing and stable structures that connect the keel, this makes it possible to have a sea vessel that can cross all seas, so that it can support the functions required by the vessel itself.

For example, cargo, passenger and even combat functions. If the keel is broken during these missions, the whole ship will burp. This is similar to a spacecraft going to space for missions.

The breakdown of the oil tanker of the tourist island country that occurred a while ago is the best proof of this. The cargo ship of the Yaga country suddenly approached the shallow water area in order to find a better network signal, thus causing the bottom keel to break into the reef, which has very serious consequences.

If the structural strength of the keel of this ship is high enough, it may be that even if it hits the reef, the whole ship will be grounded at most, and there will be no such serious environmental crisis. From this point of view, the advantages of high structural strength can be seen.

The second effect of the keel is to expand the side area of the boat, increase the parallel impedance of the boat in the water, and prevent the side wind from turning. This is particularly important for anti-wind navigation. A keel on a sailboat is supported by a central or lateral skeleton.

Likewise, spacecraft will encounter a variety of very harsh environments and tests in space, such as gravitational crises of megaplanets like Jupiter, as well as dangers such as avoiding debris impacts from asteroid belts in space, which require a very good maneuverability.

In addition, the keel also plays an important role in the weight stability of the boat, reducing the boat's tilt or reverse rotation. This point is also needed for spacecraft. If the structural strength of the spacecraft is insufficient, the spacecraft may be in danger of losing control when it is heavily manoeuvred. If it encounters such problems in a dangerous environment, it is easy to destroy the ship.

So just like these ships sailing at sea, spacecraft do have very high requirements for the structural strength of the main body. He Xingxin, the second-generation spacecraft they designed, will raise this demand and the company's senior management will be able to accept it.

“Money is not a big problem, the key is that the company's million-ton mold forging hydraulic machine now has this capability. The 500,000-ton mold forging hydraulic machine is less than a year old. Director Chen, what does your lab say?"

Lei Tiantang waved his hand to stop the discussion and ask Chen Shuiqing, chief engineer of the mold forging hydraulic machine. He was the party involved in this matter, and he was the only one who could answer this question.

“Problem-free boss! Our laboratory has already completed the design work of the 1 million tons of mold forging hydraulic press six months ago, and there are complete solutions to the problems that may be encountered in manufacturing, which can be started at any time.

After all, we started our scientific research on 500,000 tons and 1 million tons of mold forging hydraulic presses as early as the construction of 250,000 tons of mold forging hydraulic presses. If we can't complete this research and development progress node by now, we can't afford the company's strong support for our laboratory!

We have even started the design and development of 2 million tons of mold forging hydraulic machines, and have made some progress. We have also carried out relevant technical research on 3 million tons of mold forging hydraulic machines with higher tons, to ensure that we will not delay the company's demand for higher forging pressure!

The main reason why the company did not start construction of the 1 million tons of mold forging hydraulic machine is that the previous 500,000 tons of mold forging hydraulic machine has exceeded the company's actual demand for forging pressure, and the construction of 1 million tons of mold forging hydraulic machine is a waste of money and resources. After all, it is a very large expense for the company to build such a big guy. ”Chen Shuiqing introduced himself very quickly to completing the work for which he was responsible.

He and some of the company's other heads of laboratories involved in basic equipment research usually meet in the same way as little transparency. In addition to understanding the company's various related R&D progress, the main thing is to listen to these laboratories that may be involved in their responsible laboratories to put relevant demands on them.

Maybe they're not as interesting as the big star labs of companies like Fighter Labs, Rocket Labs, Missile Labs, Spacecraft Labs, etc., but those who know a little bit about them won't ignore their usual very low-key labs.

Not high profile does not mean it is not important. Thinking low profile is often the more important thing. Previously, the company made high-profile publicity in the manufacture of 100,000 tons and 250,000 tons of mold forging hydraulic presses.

But last year, after the company built a 500,000-ton die-forging hydraulic press, the company just announced a very discreet piece of tofu on the official website.

Even Lei Tiantang's favorite event to forge the Yayi gold hoop stick was no longer as advertised as before. It was only to create a smaller yayi gold hoop stick that was forged and left in the square.

Because of the 500,000 tons of mold forging hydraulic machine, the Infinite Gravity Group family now has this demand, which is used in high-end construction fields such as spacecraft and airports. Only such tons of mold forging hydraulic machines can forge components that meet the performance requirements.

But this tonnage of mold forging hydraulic press is not without demand market, but both the national side and the company side open its application channel to use in a short period of time, which is the company's dominant advantage in the high-end field, before other countries catch up, it is absolutely impossible to enter the market.

The company's 250,000 tons of die-forging hydraulic presses and the 100,000 tons of die-forging hydraulic presses below this level are enough to bring a rich profit to the company. Before there are not many competitors in this market, there is no need to invest in products with better performance.
