Eleven-blade large side-inclined propeller technology, even Western countries have not mastered the essence of it, in fact, the propeller can be regarded as a perfect round metal piece, and to make this metal piece, there are countless possibilities and schemes for making eleven blades, but just like the golden cutting point, there is only one point, which is really just right, if you miss this point, it may be counterproductive, even if the effect is good, it is very far from this perfect point, and a propeller with a diameter of more than four meters or even five meters, There are countless possibilities for a perfect point in the paddle area, a perfect point in the side slope angle, and a slight change in the shape, but if you want to master that perfect point, I am afraid that it will be difficult to touch this unique perfect point in the overall sense after millions of experiments and calculations. net

The most important reason, in addition to the design scheme, there is also the manufacturing process, the propeller manufacturing with large side slope, which requires a very high level of curvature manufacturing process, at this point, there must be a very accurate grasp of it, otherwise, once the accuracy tolerance is problematic, it will not only affect the manufacture of other propellers, but also affect the actual performance of the entire propeller.

Later, it was because of Toshiba's illegal operation that the Soviets and even the later Russians made great progress in the submarine propeller manufacturing process, and it can even be said that China's current propeller manufacturing technology and CNC machine tool technology, a considerable part of it, also through the Soviet Union, indirectly took advantage of Toshiba.

The high-level multi-pitch and large-side oblique propeller processing must be backed by a sufficiently metamorphosed precision machine tool to make it truly possible. Unfortunately, in the field of rice polishing, Dongchen is definitely the most perverted in the world

Coupled with Xiao Er's full set of advanced design schemes, coupled with the metamorphosis strength of Dongchen high-precision machining center, Zhang Wenhao dare not say anything else, it is still a piece of cake to build the world's top, highest-tech, quietest and highest thrust utilization rate of submarine propellers. Although this alone cannot make up for the fundamental shortcomings of China's nuclear submarines, at least. It can give China's nuclear submarines the ability to enter the Pacific Ocean.

Although Director Liu is very easy to communicate, he doesn't have any official position in front of Zhang Wenhao. But the routine has always been vigorous and resolute, but everything Zhang Wenhao needs, will be prepared in the fastest time, the hoisting equipment, fixed equipment and corresponding materials used in the processing of large-diameter propellers are all installed in place within two days, in addition, the entire high-precision machining center is attached to the best sound-absorbing materials at present, and the deafening cutting and grinding sound inside can not be heard outside the wall.

Zhang Wenhao and Xiao Er agreed on a most suitable design plan, and Xiao Er was also full of confidence in this seemingly ultra-difficult precision processing. It designs and transforms the machine tool, and only it can give full play to the maximum potential of this set of machine tools, in addition, every detail of the design scheme is in the "super brain" of Xiao Er, several factors add up. It is also very easy for him to do things.

The eleven-blade large side oblique propeller quietly started at noon on a sunny day, and in the entire high-precision machining center, in addition to the whole set of equipment controlled by Xiao Er, there was only Zhang Wenhao with noise-proof earmuffs, goggles and masks.

Xiao Er wants to use machine tools to perfectly reflect the excellent engineering mechanics, physics and high-precision large curvature machining technology, and the sparks of the entire machining center are flying. The large pieces of copper alloy that are cut are immediately picked up and transferred by a mobile robotic arm, and the fine metal chips that are polished are all sucked into it by a huge vacuum cleaner to avoid any unnecessary effects.

In addition, when this plant was built, it adopted a dust-free design, which ensured that Xiaoer had an absolutely ideal processing environment. …,

Ultra-high-precision processing technology, mature manufacturing technology, and unparalleled operation fit make the progress of the entire project very fast, Chapter 323 packing truck is shipped away, if the senior management is willing, I would like to go over to see the actual experimental effect, this, I have to ask you to help me apply with the above. ”

"No problem!" Director Liu blurted out: "This package is on me, I will contact the leader now, report the good news, and then ask the leader what he means, I think, they will not refuse you." ”

Director Liu couldn't help but be happy, and used a satellite phone to get in touch with the high-level line, and at the same time, those experts were still in a state of madness and couldn't extricate themselves, eleven-blade large side-tilting propeller technology, for a country like China where seven-blade propeller technology is not fully mature, the significance can not be described in words, how can this not be exciting?

Perfect design, perfect processing, destined this kind of propeller, will achieve excellent results in practical application, Zhang Wenhao even if he has money, does not have the ability to build his own submarine, he is looking forward to seeing with his own eyes what kind of breakthrough this propeller can bring to China's submarines.

Soon, Director Liu walked back excitedly, shook hands with Zhang Wenhao, and said excitedly: "The leader asked me to convey their gratitude to Dongchen, to you, and to the team behind you, you have made great contributions to the rejuvenation of our nation and our national security. You also have the qualifications to be a spectator of the whole experiment, at any stage! (Your support is my biggest motivation.) )
