Reborn in Hong Kong: The Tycoon Grows Up

Chapter 198 Three-rotor engine concept

Although I felt a little sorry for my mother, I understood a lot after Li Yulin's persuasion. The Heiyun Group is now very popular. If I celebrate my mother's birthday with great fanfare, it is inevitable that some desperadoes will take notice of me. Some things outweigh the gains, so it would be more economical to give some money to employees.

Bao Zixuan returned to MIT for his thesis defense and has been away these days. He doesn't look like a student at all, but he has contributed enough to the school that he can live and work freely in the school. All professors will be open to this student at this point, and Harry Rowland has made it clear that he will be given a graduate spot in computer science. It can be further studied in computer science.

After careful consideration, Bao Zixuan agreed. Many scientific research projects in Heiyun have not yet been completed, and Yulin Institute of Technology has not yet recruited teachers. Now it can take advantage of the opportunities to study and work in the United States. At least bringing Chinese scientific and technological talents to Hong Kong is one of his goals, no matter what the cost.

At present, Xiangjiang’s talent pool of science and engineering talents cannot support the establishment of a professional college of science and engineering. Then you can only rely on your own efforts to make these people willing to go to Xiangjiang to teach and conduct scientific research on the grounds of high welfare, treatment and support for their scientific research projects.

The direction of the thesis is clear this time. In his previous life at Rolls-Royce, Bao Zixuan developed an engine that took nearly 10 years to succeed - a three-rotor turbofan engine.

In its previous life, this was an engine developed by Rolls-Royce to break the monopoly on the engine market of North American airlines. It was an industrial pearl in the aviation world.

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

Comparison between rotary engines and traditional 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 mechanical difference between the two engines is the way in which expansion pressure is used. In a reciprocating engine, the expansion pressure generated on the top surface of the piston pushes the piston downward, and mechanical force is transmitted to the connecting rod, driving the crankshaft to rotate. Rotary Engine, In the case of a rotary engine, the expansion pressure acts on the sides of the rotor. This pushes one of the three faces of the triangular rotor toward the center of the eccentric shaft. This movement is carried out under the action of two component forces. One is the centripetal force pointing toward the center of the output shaft, and the other is the tangential force that causes the output shaft to rotate.

In the following days, engineers developed a dual-rotor engine based on the rotary engine. However, the dual-rotor engine has certain shortcomings in aircraft. Now major aerospace power companies are envisioning three-rotor engines.

Every time a rotor is added to the engine, the difficulty increases exponentially. Everyone only imagines the three-rotor engine rather than researches it. After all, the research and development of aero-engines cannot be done with just a little money. It may require billions of dollars and take decades, and the results may not be seen. Many companies are unwilling to invest in this area, which results in the world's only There are only a few aircraft manufacturing companies, and even fewer aircraft engine manufacturing companies.

In the field of aerospace engines, the disadvantage of dual-rotor engines is that the diameter of the fan and subsequent supercharging stages are large and the rotation speed cannot be too high. A multi-pole low-pressure turbine has to be matched behind the engine so that the fan rotation speed can be reduced to the optimal level as much as possible. Rotating speed. One solution to this problem is to use a three-rotor engine.

At the same time, you can also understand it as equipping the fan with a turbine drive so that the three rotors of low pressure, medium pressure and high pressure can work as optimally as possible. But this will also cause other problems. One more shaft requires one more bearing, which will pose challenges to the reliability, volume, layout and weight of the engine.

It can be said that the three-rotor engine of Rolls-Royce in the previous life was forced out by competitors. Because the size of the military products market is limited, North American partners in civil aviation are now considering their own countries' general and inclusive aviation. Faced with this embarrassing situation, Rolls-Royce decided to rely on his true ability to use his big move - a three-rotor engine. Of course, one more rotor means one more core machine, which makes it more difficult to grasp the difficulty of matching.

When Rolls-Royce came into power, it still only accounted for 8% of the entire large civil aviation engine market despite the competition from its rivals General Electric and Pratt \u0026 Whitney. At that time, aircraft manufacturers were developing new wide-body twin-engine aircraft that could be equipped with high-thrust engines, such as the Boeing 777 and Airbus A330, in order to comply with ETOPS standards when they were put into service.

With the technology and experience of the RB211, Rolls-Royce announced its decision to enter the large civil aviation engine market on January 1 to strengthen its own competitiveness and give airlines more choices when choosing engines for their aircraft.

Subsequently, Rolls-Royce submitted a "development investment" plan to the British government. The 1800 series cost 200 million pounds; in 2001, the development of Trent 500 and 250 million pounds was done, while the Trent 1000 series did not require government capital injection.

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 engine performance and structure. The British have invested approximately 500 million pounds in the three-rotor engine project. Bao Zixuan has specially prepared US$1 billion for this purpose, aiming to acquire this technology and patent ten years in advance.

Without the three-rotor engine, it’s time to see when Rolls-Royce will rise. This is just the first step in revenge. There will be many surprises waiting for this aviation power giant in the future.

Bao Zixuan started writing a paper on a three-rotor turbofan engine based on his previous experience and current mature scientific and technological achievements. Once the paper is completed, he will also apply for a patent simultaneously. After all, such important scientific research results cannot be cheapened by others, so Bao Zixuan began to prepare his graduation thesis seriously in the MIT library.

Although I understand all the working principles and technical features, there is nothing about the three-rotor engine, the most complicated machine in the world. Bao Zixuan cannot program the entire industrial production process alone, nor can he create it alone.

It is a system engineering that requires the cooperation of a series of disciplines such as materials, aerodynamics, and mechanical processing. Bao Zixuan can only write out the concepts and working principles now, which is enough.

The rest required the cooperation of other engineers and the use of Soviet materials science. Bao Zixuan is already preparing to go to Inner Mongolia, Jiangxi, Guangdong, Sichuan and other places to purchase rare earth mineral deposits as soon as China agrees to the entry of Hong Kong capital. He can no longer afford to discount Japanese, Korean and American companies. These are all industrial gold. It seems that you can ask Mr. Huo to introduce them in advance, otherwise there is really no way.

Once rare earth resources are available, combine them with Soviet titanium alloy processing technology. Then the basic conditions for aircraft manufacturing have been solved, and all that remains is to purchase machinery and equipment and recruit talents around the world.

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

After a month of hard work, Bao Zixuan’s thesis was finally completed. He now has to print three copies of his thesis, one will be sent to MIT for review, one will be sent to the University of Oxford in the UK, and one will be kept for himself for defense.
