Although I felt a little sorry for my mother in my heart, I understood a lot after Li Yulin's persuasion. The Black Cloud Group is now making a big splash, and if he celebrates his mother's birthday with great fanfare, he will inevitably be remembered by some outlaws. Some of the gains outweigh the losses, or send some money to employees to be more affordable.

Bao Zixuan returned to MIT to defend his dissertation and was out these days. He didn't look like a student at all, but he did contribute enough to the school that he could live and work freely. All the professors will be open to this student at this point, and Harry Rowland has made it clear that he will be offered a graduate slot in computer science. It can go directly to the computer major in September to continue its studies.

On this point, after careful consideration, Bao Zixuan still agreed. Many of Heiyun's scientific research projects have not yet been completed, and Yulin Institute of Technology has not yet recruited teachers, so it can now take advantage of the opportunities to study and work in the United States. At least to bring Chinese scientific and technological talents to Xiangjiang, this is one of his goals, and he will not hesitate to spend any cost.

At present, with the talent pool of science and engineering in Hong Kong, it cannot support the establishment of a professional college of science and engineering. Then they can only rely on their own efforts to make these people willing to go to Xiangjiang to teach and engage in scientific research on the grounds of high benefits, treatment and support for their scientific research projects.

The direction of the paper has been clear this time, Bao Zixuan has developed an engine that took nearly 10 years to succeed in Rolls-Royce in his previous life - the three-rotor turbofan engine.

In the previous life, this was an engine developed by Rolls-Royce in order to break the monopoly of North American airlines in the engine market, and it is an industrial pearl in the aviation industry.

The rotary engine was invented by the German Figarz Wankel, who solved some key technical problems and successfully developed the first rotary engine on the basis of summarizing the research results of his predecessors. Rotary engines use a triangular rotor rotational motion to control compression and emissions, as opposed to the linear motion of a traditional reciprocating piston engine.

Comparison of rotary engines with conventional reciprocating engines: Both reciprocating engines and rotary engines rely on the expansion pressure generated by the combustion of an air-fuel mixture to obtain rotational power. The difference in the mechanism of the two engines is the way in which the expansion pressure is used. In a reciprocating engine, the expansion pressure generated on the top surface of the piston pushes the piston downward, and the mechanical force is transmitted to the connecting rod, which drives the crankshaft to turn. Rotary engines, for rotary engines, the expansion pressure acts on the sides of the rotor. This pushes one of the three faces of the triangular rotor towards the center of the eccentric axis. This movement is carried out under the force of the two components. One is the centripetal force pointing towards the center of the output shaft, and the other is the tangential force that makes the output shaft turn.

In the following days, engineers developed twin-rotor engines on the basis of rotary engines, but twin-rotor engines have certain defects in aircraft, and now major aviation power companies are expecting such as three-rotor engines.

The difficulty of each additional rotor of the engine increases exponentially, and everyone only thinks more about the three-rotor engine than the research. After all, the research and development of aero engines can not be done with a little money, it may take billions of dollars, spend decades, and may not see the effect, many companies are unwilling to invest money in this regard, which causes only a few aircraft manufacturing enterprises in the world, and aircraft engine manufacturing enterprises are even fewer.

In the field of aero engines, the disadvantage of the twin-rotor engine is that the diameter of the fan and the subsequent booster stage is large, and the speed cannot be too high, and the multi-pole low-pressure turbine has to be matched behind the engine to reduce the fan speed to the optimal speed as much as possible. One solution to this problem is to use a three-rotor engine.

At the same time, you can also understand that you are equipping the fan with a turbine drive, so that the three rotors of low, medium and high pressure can work at the optimal speed as much as possible. However, this can also lead to additional problems, as one more shaft requires one more bearing, which can challenge the reliability, volume, layout and weight of the engine.

It can be said that the three-rotor engine of Rolls-Royce was forced out by competitors in the previous life. Due to the limited size of the military market, the North American partners of civil aviation are now considering the universal and inclusive nature of their countries. Faced with this embarrassing situation, Rolls-Roy decided to rely on his real skills to hold back the big move, that is, the three-rotor engine. Of course, one more rotor indicates one more core machine, which is more difficult to grasp in terms of matching difficulty.

When Rolls-Royce was privatized in 1987, it still accounted for only 8% of the overall large civil aircraft engine market, although it already owned the RB211 series engines, despite the competition from rivals General Electric and Pratt & Whitney. At that time, aircraft manufacturers were developing new wide-body twin-engine aircraft, such as the Boeing 777 and Airbus A330, that could be equipped with high-thrust engines, in order to be ETOPS-compliant by the time they entered service.

Leveraging the technology and experience of the RB211, Rolls-Royce announced at the 1988 Airshow that it had decided to enter the large commercial engine market in order to strengthen its competitiveness and give airlines more choice when choosing engines for their aircraft.

Subsequently, Rolls-Royce submitted a "development investment" proposal to the UK government. In 1997, the development of the Trent 800 series was £200 million, and in 2001, the development of the Trent 500, 600 and 900 series was £250 million, while the Trent 1000 series did not require government investment.

In his previous life, Bao Zixuan participated in the upgrade and transformation of the entire Rolls-Royce three-rotor engine, and was very familiar with the engine performance and structure. The British have invested around £500 million in the three-rotor engine project. Bao Zixuan specially prepared $1 billion for this purpose, which is to get this technology and patent ten years ahead of the curve.

Without the three-rotor engine, it will be only the first step in revenge to see when Rolls-Royce will rise. There will be many surprises waiting for the aviation power giant in the future.

Bao Zixuan combined the experience of his previous life and the current mature scientific and technological achievements to write a paper on the three-rotor turbofan engine, and once the paper was completed, he would also apply for a patent at the same time. After all, such an important scientific research achievement cannot be cheapened by others, so Bao Zixuan began to seriously prepare his graduation thesis in the MIT library.

Although I understand all the working principles and technical characteristics, I am the most complicated machine in the world about the three-rotor engine. It's not that Bao Zixuan can write the entire industrial production process alone, let alone make it by one person.

It is a systems engineering that requires a series of disciplines such as materials, aerodynamics, and machining. Bao Zixuan can only write out the concept and working principle now, and this is enough.

The rest will require other engineers to work with, and Soviet materials science will also be used. Bao Zixuan is already preparing to buy rare earth deposits in Inner Mongolia, Jiangxi, Guangdong and Sichuan as soon as China agrees to enter Hong Kong. These are all industrial gold, it seems that you can ask Huo Lao to introduce them in advance, otherwise there is really no way.

Once there are rare earth resources, combined with the Soviet titanium alloy processing technology. Then the basic conditions for aircraft building have been solved, and all that remains is to purchase machinery and equipment around the world and recruit talent.

Yulin Institute of Technology will set up a special aviation power major at that time, which is to recruit the best aviation talents in the world.

After a month of hard work, Bao Zixuan's paper was finally written. He now prints three copies of his dissertation, one for review at the Massachusetts Institute of Technology, one for sending to the University of Oxford, England, and one for his defense.
