Liu Xinyu was about to stand up, but Yang Dongsheng waved at him, "Let them drink! One piece and one piece are the way of civil and martial arts."

"But..." Liu Xinyu was still worried.

Yang Dongsheng smiled, "Don't worry, this is our own hotel, as long as you don't book the hotel!"

As soon as Yang Dongsheng finished speaking, he heard a bang from outside, followed by someone yelling.

A group of people rushed out, only to find that a wine bottle had been broken in the corridor, a fire was burning, and two shirtless men, one tall and one short, were trying to stamp it out.

But the alcohol got on the shoes, and soon even their army boots were on fire.

The two stomped their feet like they were tap dancing.

Yang Dongsheng thought, are these two guys here to slap him in the face?
Everyone stepped forward to help, and first used a dry powder fire extinguisher, but it didn't work at all.

Fortunately, the fire was not big, and the people from the hotel rushed over with fire blankets, and finally put out the fire.

Liu Xinyu yelled at the two old men.

"Send them to the hospital and treat their wounds!" Yang Dongsheng saw that the trousers of the two old men were burnt, so he gave instructions to the hotel manager.

Liu Xinyu said, "This group of old men, everything else is pretty good, but they are addicted to alcohol! And they are very tasteless. After drinking, they go crazy with alcohol. I heard that after entering the Winter Palace, XX's first order It is to destroy all the wine in the cellar of the Winter Palace, otherwise the October Revolution may be over!"

Yang Dongsheng said, "Send them to the vacation villas in Qiong Province. Even if the houses over there are on fire, at most one will be burned."

After the talks, Yang Dongsheng moved all kinds of resources in Siberia to the country as much as possible.

Although there are many mines, such as lignite, the lignite stored in his hand is enough to burn until the sky is old.

But even if he can't use it, the mine must be removed, and the one that cannot be removed must be destroyed.

Moscow will not allow a foreign company to occupy so many Siberian minerals, and they may find some excuse to take them back someday, especially if most of these minerals are still robbed.

The resumption meeting of People's Bank's first listing ended in a complete failure, and the opinions could not be unified, especially because there was Yang Dongsheng who didn't want to go public at all.

After finishing the business in Huajing, Yang Dongsheng returned to Shanghai.

As soon as he returned to Shanghai, Yang Dongsheng took a look at the latest progress of Dongsheng Chemical's carbon fiber.

Under the guidance of Nobuyoshi Hosokawa, whom Yang Dongsheng "poached" from Toray, Dongsheng Chemical's first PAN-based carbon fiber expansion test production line was completed and put into operation. According to the design, it can produce 350 kg of carbon fiber per month.

This level is considered very good. In 1976, the first PAN-based carbon fiber expansion test production line of the Northwest Coal Chemical Industry Institute had a monthly production capacity of less than 200 kg.

In the 70s, Toray's first T300 carbon fiber production line produced only 1 ton per month.

After the first batch of carbon fibers were produced, the tested strength reached 3900MPa, and the tensile modulus reached 240GPa.

According to the data released by Toray, the performance of their batch of carbon fibers has exceeded the level of T300 strength of 3530MPa and tensile modulus of 230GPa.

This is due to the higher raw silk they produce than T300, and the carbonization process accumulated by Toray for many years.

The manufacturing process of carbon fiber is basically the same. …

The raw silk is produced, and then carbonized, so that the nitrogen and hydrogen elements in the raw silk are released to form ammonia and hydrocyanic acid. During this process, the raw silk will gradually crystallize, and finally a fibrous graphitized carbon product is obtained.

To produce higher performance carbon fiber, first of all, it is necessary to prepare the raw silk with the highest purity possible to reduce the impact of impurities on the finished carbon fiber;

Secondly, during the carbonization process, it is necessary to remove the components other than carbon in the raw silk as much as possible, and provide a suitable temperature to gradually crystallize the carbon that has removed other components.

Yang Dongsheng can boldly guess that the end of the carbon fiber is likely to be graphene.

According to the calculation of the graphene research team of Dongsheng Semiconductor, the strength of graphene can reach 130GPa, and the tensile modulus can reach 1.0TPa.

Even better is Toray's M-series high-modulus carbon fiber, which is further carbonized on the basis of their T-series high-strength carbon fiber.

This means that on the basis of high-strength carbon fibers with better performance, they can further carbonize high-performance high-modulus carbon fibers.

350 kilograms per month, this output does not need to be exported at all, and Dongsheng Group can digest it by itself.

Not long after returning to Shanghai, Yang Dongsheng welcomed another group of guests.

The "Yangtze River" high-bypass ratio aero-engine has been approved by the military after repeated tests by the Air Force and will be applied to domestic large-scale strategic transport aircraft.

"Yangtze River" also received its official number - WS-20.

The Air Force ordered 280 turbofan-20 aero engines in the first batch. According to the fact that each strategic transport aircraft is equipped with four engines, even if several prototypes and spare engines are to be manufactured for the flight test, the Air Force will also order 50 in the first batch. The above large strategic transport aircraft.

It seems that the Air Force is very satisfied with this strategic transport aircraft with a higher degree of localization!
According to the original calculation of Dongsheng Heavy Industry Vice President Wang, they can fully recover the cost as long as they sell 300 engines.

After completing this order, they have basically recovered the cost.

In addition, the Air Force also asked them whether they could shrink the fan and compress the engine diameter to 1.4 meters.

The Air Force is preparing to improve a certain domestic bomber.

Along with the Air Force are the Rongcheng Aircraft Manufacturing Plant, which manufactures fighter jets, and the Zhucheng Aero Engine Research Institute, which develops engines.

Another high-thrust and low-bypass ratio aeroengine "Yellow River" manufactured by Dongsheng Heavy Industry has entered the list of alternative engines for a key domestically produced single-engine fighter and the next-generation twin-engine heavy fighter of the Rongcheng Aircraft Manufacturing Plant.

In addition, Dongsheng Heavy Industry also signed a contract with Zhucheng Aero-Engine Research Institute to jointly develop a medium-thrust small-bypass ratio aero-engine, which is temporarily named "Wujiang" internally.

Among them, Dongsheng Heavy Industry is responsible for the core engine part, and Zhucheng Aero Engine Research Institute is responsible for the front end part of the engine.

The prototype of Dongsheng Heavy Industry's high-thrust and small-bypass ratio aero-engine "Yellow River" was originally General Electric's high-thrust engine F110.

The F110 has the same core engine as General Electric's medium-thrust engine F404. When the F110 engine was developed, it also borrowed a lot from the fan, afterburner and nozzle technology of the F404.

However, they did not get the F404 sample after all, and this medium-thrust engine was obviously developed for an export-oriented fighter, and the output would not be very high.

With this energy, it is better to focus on the development of the next generation of engines.

After the signing ceremony, a middle-aged man with a golden pine branch on his shoulder asked, "I heard that Mr. Yang is building drones?"
