Chapter 1267: Processing propeller

The Scud missile weighs only less than six tons, while the Julang-1 missile weighs a full 15 tons. Under such circumstances, it is obviously impossible to modify it with a simple infantry fighting vehicle with an off-road chassis of the North Industries Corporation. Yes, the gap is huge. When Qin Guan said this, Heribala frowned. According to Qin Guan's meaning, this missile is a heavy type and requires a large launch vehicle. Then, his existing technology is almost They are all unusable.
You know, for a higher level, all of them need to be re-developed, such as the three most important parts, the engine, the gearbox and the rear axle, all of which need to be expanded by one model.
The engine has achieved 400 horsepower at its maximum, and the current demand has to be more than 800 horsepower, and the gearbox and rear axle also need to be thicker and larger. It can be said that it is completely renewed. It's just research and development.
This challenge made Heribala a little excited. For him, what he needed was transcendence time and time again. Only now that he was step by step would not satisfy him. He was eager to explore new things.
Looking at the wheeled infantry fighting vehicle, Qin Guan seemed to be thinking about something.
Now, the SCUD missile is becoming a popular item on the international market. This kind of missile shines in the war between the date palm country and the Shah state.
In the international market, there is also a great demand for such short-range ballistic missiles. Why doesn't China develop a ballistic missile with a range of less than 300 kilometers, specifically for export?
Three hundred kilometers, this is an international regulation. If you want to export ballistic missiles, you must abide by this agreement. In fact, this regulation is just a piece of paper for Han. Han did not sign on it. Han wanted to export. Just export, any range is fine.
However, with the continuous development in the future, it is better to abide by the rules of the international market. Now, in Qin Guan's mind, he thinks of Dongfeng-11. This kind of thing is used to replace Scud, that is the best. Yes, especially, it uses a solid rocket motor, which is much faster than a Scud missile.
These are all lucrative gadgets for arms exports.
"Brother Guan?" Heribala said softly.
Qin Guan came out of his thoughts and said, "Go, let's go and see our machining center."
In North Industries Corporation, it has the world's most advanced CNC machine tools. They not only produce it by themselves, but also process them to the outside world. It has become the most famous processing center in the whole country. Some high-precision processing products come from North Industries Corporation.
When Qin Guan walked in, he saw the largest multi-axis CNC milling machine in the machining center rumbling, and inside, a large copper ingot was being cut.
"Propeller?" Qin Guan asked.
"Yes, required by the Navy, this kind of large seven-blade large skew propeller can only be processed here." Heribala said.
The marine propeller is made by cutting a large piece of copper ingots little by little. It is large in size and requires high precision. In the past, it was impossible to machine in China. Without a multi-axis linkage CNC machine tool, it would not be able to cut. With such a complex geometric shape, without this special shape, the noise of the propeller under water will increase.
Now, domestic 039-class submarines and newly-built nuclear submarines are processed from the processing center of the northern heavy truck factory for them.
Watching the copper ingots rotating back and forth in several axis directions, while the cut copper wires were flying, Qin Guan's eyes slowly lit up.
Now, 1982 is about to pass, 1983 is about to come, and in the spring of 1983, something big will happen.
Qin Guan knew this incident clearly. This was the famous Toshiba machine tool incident in history.
One late night in the early spring of 1983, the 10,000-ton freighter "Old Communist" drove by Xiongguo Shipping Company to the island country departed from Shibaura Wharf in the island country and transported dozens of boxes of parts of the "five-axis CNC machine tool".
Xiong's purchase of these CNC machine tools not only improved the propulsion performance of the submarine, but also improved the propellers of the new aircraft carrier under construction at that time. This is the sensational "Toshiba Company Violated Batumi Export Incident".
Because of Xiong's backwardness in the development of high-tech, especially electronic technology, the processing accuracy has always been behind the Western world. Their submarines cannot use precision-machined propellers. The noise of their submarines under water has always been better than that of Yingguo. An order of magnitude higher.
For island nations, as long as they make money, they dare to do anything. The consequences of this incident are serious: For the first time, the Eagle State Navy loses its advantage in underwater sound detection against Bear State Navy ships, and Xiong State’s submarines have really become The oceanic black hole!
This time, our own drove out of the bear country's submarine from underwater, which must have stimulated the bear country's navy even more. They will definitely import this secret machine tool from the island country.
Hmph, since I'm here, of course I won't let this happen.
For some reasons, Qin Guan has always been dissatisfied with the islanders, especially the ninjas of the islanders. He also wanted to attack Qin Guan. Although this incident has passed, Qin Guan has always been dissatisfied with the islanders. of.
In terms of history, an upright Han national would never really be friends with the islanders. This time, Qin Guan had to do his part and confuse the islanders’ business with Toshiba. The reputation of the company was dissatisfied, and the people of Yingguo were dissatisfied with the island country.
This matter should also be laid out.
Qin Guan thought secretly in his heart that the propeller he was producing was associated with this trade between the bear country and the island country, and now he thought of being able to cheat the people of the bear country and the island country, and smiled on his face.
"This is our most secret place, we must protect the safety here." Qin Guan said to Heribala.
Heribala nodded: "Yes, the security measures here are the strictest. At the same time, our workers here are also censored. They must have good thinking and no family issues before they can enter the processing center."
The arrangement of Heribala made Qin Guan satisfied. The workers here have the highest wages. At the same time, they are exposed to extremely top secrets. It can be said that there must be someone outside who wants to dig them away. If they leave , Will also take away the secrets here.
This kind of loss is not only the loss of the northern heavy truck factory, but also the loss of the entire country, because the digging of them will probably be a foreign company.
