Even Western countries have not mastered the essence of the eleven-bladed large-bladed propeller technology. In fact, the propeller can be regarded as a perfectly round metal sheet, and it is necessary to manufacture this metal sheet into eleven blades.
There are countless possibilities and solutions, but just like the golden cutting point, there is only one point that is truly just right. If you miss this point, it may be counterproductive. Even if the effect is good, it is still far from this perfect point, and a
For a propeller with a diameter of more than four meters or even five meters, there is a perfect point for the propeller area, a perfect point for the side angle, and there are countless possibilities for subtle changes in the shape. But to master that perfect point, I am afraid there are hundreds of possibilities.
After thousands of experiments and calculations, it is difficult to find this unique and perfect point in the overall sense.
The most important reason is that in addition to the design plan, there is also the manufacturing process. The manufacture of propellers with large side slopes requires a very high level of curvature manufacturing process. This point must be extremely precise, otherwise, once
There is a problem with the precision tolerance, which not only affects the manufacturing of other blades, but also affects the actual performance of the entire propeller.
The Soviets at that time did not have the ability to do such detailed work. Later, it was because of Toshiba's illegal operations that the Soviets and later the Russians made great progress in the manufacturing process of submarine propellers. It can even be said that China
A considerable part of the current propeller manufacturing technology and CNC machine tool technology also passed through the Soviet Union, indirectly taking advantage of Toshiba.
High-level multi-blade and large-skew propeller processing must be supported by sufficiently abnormal precision machine tools to truly realize it. Unfortunately, Dongchen is definitely the most abnormal in the world in the field of rice manufacturing.
of...
In addition, the waiter has a complete set of advanced design solutions. Coupled with the abnormal strength of Dongchen's high-precision machining center, Zhang Wenhao dare not say anything else, creating the world's best, with the highest technological content, the best silent effect, and the best utilization of thrust.
The submarine propeller with the highest efficiency is still a piece of cake. Although this alone cannot make up for the fundamental shortcomings of China's nuclear submarines. But at the very least, it can give China's nuclear submarines the ability to enter the Pacific.
Although Director Liu is very easy to communicate with and does not show any official airs in front of Zhang Wenhao, he has always been vigorous and resolute in his work routine. Whatever Zhang Wenhao needs, he will prepare it as soon as possible, including the hoisting equipment used to process large-diameter propellers and fixing them.
The equipment and corresponding materials were all installed within two days. In addition, the interior of the entire high-precision machining center was covered with the best sound-absorbing materials at present. The deafening sound of cutting and grinding inside was heard outside.
You can't even hear the walls.
Zhang Wenhao and Xiaoer agreed on the most suitable design plan, and Xiaoer was full of confidence in this seemingly extremely difficult precision processing. Only he himself could bring out the maximum potential of the machine tools he designed and modified.
potential, and every detail of the design plan is in Xiao Er's "super brain". The combination of these factors makes him do things with ease.
The eleven-blade large canted propeller started work quietly on a sunny noon. In the entire high-precision machining center, apart from the complete set of equipment controlled by the waiter, there was only Zhang Wenhao wearing noise-proof earmuffs, goggles, and a mask.
The waiter wants to use the machine tool to perfectly embody the excellent engineering mechanics, physics and high-precision large-curvature processing technology. Sparks fly throughout the machining center, and the large piece of copper alloy that is cut will be immediately taken care of by a mobile robotic arm.
The fine metal chips that are picked up, transferred, and polished are all sucked in by the huge vacuum device to avoid any unnecessary impact.
In addition, when this factory was built, it adopted a dust-free design, ensuring that the waiter has an absolutely ideal processing environment.
Ultra-high-precision processing technology, mature manufacturing technology, and unparalleled operational fit made the entire project progress very quickly. The first eleven-blade large side-inclined propeller was completed in less than five days.
Processing completed!
The entire propeller is polished as smooth as a mirror. Every curve and every curved surface is natural. There are almost no rigid lines. There is not a single extra line or a piece of extra metal on the entire propeller. It is perfect.
Like exquisite industrial handicrafts.
Even the Americans have no way of mastering the processing technology of such an eleven-blade large side-inclined propeller. Zhang Wenhao has no doubt that the real value of this propeller is that if someone takes a high-definition photo from the front, it will only be the perfect dynamics in the photo.
The shape, in the eyes of Americans, is at least more valuable than an Ohio-class strategic nuclear submarine worth US$2 billion. If Americans were asked to bid for this propeller, they would even be willing to spend the price of five Ohios to buy it.
The technology contained in this propeller cannot be measured in terms of money. It has enough capabilities to affect a country's national defense strength.
Although the Americans promote the China threat theory on the surface, in fact, they are quite disdainful of China's nuclear strike capabilities. China's strategic nuclear missiles are far less deterrent than Russia's Topol M. Whether launched from a silo,
Whether it is a land-based mobile launch, it is difficult for the missile to break through the US missile defense system, and the sea-based nuclear strike force is even more weak in the eyes of the Americans.
There are two most critical reasons. First, China's submarine-launched nuclear missiles have a maximum effective range of only about 8,000 kilometers. They cannot cover the entire United States in China's offshore waters. Only by entering the Pacific Ocean can they have the capability to cover the entire United States.
However, here comes the second key reason, which is: under the supervision of the Americans, it is very difficult for China's strategic nuclear submarines to enter the Pacific Ocean.
Among them, the biggest problem is noise!
It is noisy. In the face of the anti-submarine technology of the United States and Japan, Chinese submarines cannot quietly break through the U.S. and Japanese blockades and enter the Pacific. However, if the noise problem can be solved, everything will be different! The United States and Japan will soon
It is difficult to capture the movements of Chinese submarines, and the discovery rate will be greatly reduced. As a result, the probability of Chinese submarines carrying nuclear bombs into the Pacific Ocean will also greatly increase. As long as they enter the Pacific Ocean, they may penetrate deep into the throat of the United States.
National defense technology sometimes undergoes earth-shaking changes due to the improvement of one component.
It took Zhang Wenhao ten days to complete the manufacture of two eleven-blade large side-inclined propellers. After the completion of the two propellers, Zhang Wenhao immediately informed Director Liu and brought submarine experts to Dongchen for inspection and acceptance, and prepared complete transportation
method, transport these two propellers away.
Since Zhang Wenhao did not open the high-precision machining center to anyone during the manufacturing process, nor did he tell Director Liu that what he wanted to manufacture was not a seven-blade propeller, but an astonishing eleven-blade propeller. Therefore, Director Liu
When they came with four core experts and a senior military officer, they didn't know what was waiting for them inside until they reached the door.
Several people were arranged to enter the high-precision machining center late at night. The door was opened and they first entered an isolation room. After everyone entered the isolation room, the door was closed and the isolation door slowly opened. However, at this time, the high-precision machining center had stopped working.
The entire machining center seemed extremely quiet. The most important thing was that there were no lights on, so no one knew what kind of surprises were waiting for them in the dark factory building in front of them.
Director Liu was in the dark, looking in the direction of Zhang Wenhao, and said with a smile: "Comrade Zhang, it's already this time, why are you still playing mystery with us?"
Zhang Wenhao smiled slightly and said: "I'm afraid of scaring you, so I have to prepare you mentally in advance. No matter what you see later, remember to stay calm as the first priority."
Officer Liu couldn't help but urged, smiling and urging: "Okay, okay, I've never seen big winds and waves, so stop being pretentious and quickly turn on the lights so we can see!"
Zhang Wenhao said to the waiter in his heart: "Xiao Er, are you ready? Let some people have their eyes opened!"
The waiter laughed and said: "Boss, don't you trust me when I do things? I'm afraid they may have a bad psychological quality and have a heart attack because of these two things!"
Zhang Wenhao said happily: "Okay, let's stop talking nonsense and let's power the lighting system!"
"Okay!"
In an instant, the surrounding high-power lighting systems were activated instantly. The moment the lights came on, two extremely bright propellers were hung in the air, and the refracted light almost blinded everyone for a short time.
Luckily for Director Liu, when the other four top experts saw the two suspended 11-blade large side-inclined propellers, they shouted wildly and rushed over immediately.
The eleven-bladed large-bladed propeller technology is a cutting-edge technology that is coveted by countries with nuclear submarines around the world. Even China has designed theoretical drawings, but because it does not have the processing capabilities, this design can only stay at
At the drawing stage, however, they are all experts and can see at a glance the characteristics of the curvature, curve, accuracy and overall coordination of these two propellers. Although they do not know how this thing will perform after it is launched into the water, just this
This unparalleled manufacturing process has already made them wildly excited!
The four experts circled around the two propellers and watched non-stop. Some couldn't help trembling and stroking the smooth surface of the propellers. Others couldn't control their emotions and kissed the cold surface of the propellers, excited.
His eyes were filled with tears.
"Awesome!" A gray-haired old man said with tears streaming down his face: "Such a perfect manufacturing process is something I have never dreamed of. This manufacturing process has definitely surpassed any other country in the world.
No country in the world has the ability to manufacture such a perfect propeller. It is so powerful and it is so gratifying!"
"Old Qu!" A slightly younger middle-aged man on the side supported the old man who was crying and extremely unable to control himself, and said with tears: "With this manufacturing technology, the actual combat capabilities of our submarines will be greatly improved.
Promotion, now you finally get what you want!"
"It's more than just my wish!"
The old man kept shaking his head and sighed: "My lifelong dream is to hope that the propeller technology of Chinese submarines can reach the level of the American Ohio-class submarines. Even the early technological level of Ohio is enough. But what I didn't expect is that we
Now, there is such a powerful manufacturing process, and it is not just a manufacturing process! Xiao Zhao, look at the shape design of this propeller, the large side angle of each blade, even more exposed than in the United States
The Ohio-class is deeper, and the blades seem to be more streamlined than the Ohio-class, and every curve is perfectly designed. Not to mention the manufacturing process, the shape design alone is definitely the best in the world!"
Another expert blurted out: "This is just right. Our new submarine has already tested the previous three seven-blade propellers, and the results were not satisfactory. Now, we should transport these two propellers back as soon as possible and try them out immediately after installation.
Look how powerful it is!"
Officer Liu looked at Zhang Wenhao in astonishment and blurted out: "Comrade Zhang, tell me the truth, how much improvement can this propeller design bring?"
Zhang Wenhao smiled and said: "The so-called improvement here is only at the level of simulation testing. The specific actual use effect still needs to be tested by facts. You should quickly arrange to pack these two propellers and use special
The container truck will be transported away. If the senior management is willing, I would like to go there to see the actual experimental results. For this, I would also like to trouble you to apply for it with the above."
"No problem!" Director Liu blurted out: "This is all my responsibility. I will contact the leaders now to report the good news, and then ask the leaders what they want. I think they will not reject you."
Director Liu couldn't help his joy and used a satellite phone to contact the senior management through a dedicated line. At the same time, those experts were still in a state of madness. The eleven-blade large side-inclined propeller technology was completely different to China's seven-blade propeller technology.
For a country that is not fully mature, its significance cannot be described in words. How can this not be exciting?
Perfect design and perfect processing are destined to achieve excellent results in practical applications. Even if Zhang Wenhao is rich, he does not have the ability to build a submarine by himself. He is looking forward to seeing with his own eyes what this propeller can do.
What kind of breakthrough will it bring to China's submarines?
Soon, Director Liu came back excitedly, shook hands with Zhang Wenhao tightly, and said excitedly: "The leader asked me to convey their gratitude to Dongchen, to you, and to the team behind you. You have done everything for us.
The national rejuvenation of Dongchen has made a huge contribution to our national security. Regarding all subsequent tests of new submarines, you are free to decide whether to participate. If Dongchen has other advanced technologies in other aspects, the leaders are very welcome to Dongchen to take them.
Come out and contribute to national defense construction. Even if you don’t, you still have the qualification to watch every link of the entire experiment!”
