Reborn Xiangjiang Tycoon Growth

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, and if I celebrate my mother's birthday with great fanfare, I will inevitably be remembered by some desperadoes. If the gain is not worth the loss, it is better to send some money.

Make it more affordable for 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 the professors are here

This student will be spared in every aspect, and Harry Rowland has made it clear that he will be given a postgraduate quota in computer science. He can directly enter the computer science major to continue his studies in September.

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 is possible to take advantage of the opportunities to study and work in the United States. At least, the Chinese technologists

Bringing talents to Xiangjiang is one of his goals, no matter how much it costs.

At present, the talent pool of science and engineering in Xiangjiang cannot support the establishment of a professional college of science and engineering at all. Then we can only rely on our own efforts to make these people willing to teach in Xiangjiang on the grounds of high welfare, salary and support for their scientific research projects.

and engage in scientific research.

The direction of the thesis is clear this time. In his previous life, Bao Zixuan worked at Rolls-Royce to develop 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 previous research results, he solved some key technical problems and successfully developed the first rotary engine. The rotary engine uses a triangular rotor to rotate

Movement to control compression and emissions is very different from 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 air-fuel mixture to obtain rotational force. The mechanical difference between the two engines lies in the way the expansion pressure is used. In the 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 to drive the crankshaft to rotate. For rotary engines, for rotary engines, the expansion pressure acts on the sides of the rotor. Thus, the three faces of the triangular rotor are

One is pushed to the center of the eccentric shaft. This movement is carried out under the action of two component forces. One is the centripetal force pointing to the center of the output shaft, and the other is the tangential force that rotates the output shaft.

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 just imagines the three-rotor engine rather than researches it. After all, the research and development of aero-engines cannot be done with a little money. It may require billions of dollars and take decades.

And the results may not necessarily be seen. Many companies are unwilling to invest money in this area, which means that there are only a few aircraft manufacturing companies in the world, 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 the subsequent supercharging stage is large, and the rotation speed cannot be too high. A multi-pole low-pressure turbine has to be matched behind the engine to reduce the fan rotation speed to the optimal level as much as possible.

Speed. One solution to this problem is to use a three-rotor engine.

At the same time, you can also understand that the fan is equipped with a turbine drive, so that the three rotors of low pressure, medium pressure and high pressure can work as much as possible to the optimal speed. But this will also cause other problems. One more shaft will

One more bearing will pose challenges to the reliability, size, layout and weight of the engine.

It can be said that Rolls-Royce's three-rotor engine was forced out by competitors in the previous life. Because the scale of the military product market is limited, the North American partners of civil aviation are now considering General Motors and Pratt & Whitney in their own countries. Faced with this embarrassing situation, Rolls-Royce decided to rely on

My real ability is to hold back the big move - the three-rotor engine. Of course, one more rotor means one more core engine, which makes it more difficult to grasp the difficulty of matching.

When Rolls-Royce completed its privatization in 1987, under the competition from its rivals General Electric and Pratt & Whitney, although it already owned the RB211 series engines, it still only accounted for 8% of the entire large civil aviation engine market. At that time,

Aircraft manufacturers are developing new wide-body twin-engine aircraft that can be equipped with high-thrust engines, such as the Boeing 777 and Airbus A330, to ensure that they meet etops standards when they are put into service.

After acquiring the technology and experience of the RB211, Rolls-Royce announced its decision to enter the large civil aviation engine market at the 1988 Air Show in order to strengthen its own competitiveness and allow airlines to have more choices when choosing engines for their aircraft.

Subsequently, Rolls-Royce submitted a plan to the British government. In 1997, the development cost of the Trent 800 series was 200 million pounds; in 2001, the development cost of the Trent 500, 600, and 900 series was 250 million pounds, while the Trent 1000 series was

No government funding is required.

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 invested approximately 500 million pounds in the three-rotor engine project. Bao Zixuan specially prepared for this

1 billion US dollars is to acquire this technology and patent ten years in advance.

Without the three-rotor engine, it remains to be seen 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.

Combining his previous experience and current mature scientific and technological achievements, Bao Zixuan began to write a paper on the three-rotor turbofan engine. Once the paper is completed, he will also apply for a patent simultaneously. After all, such important scientific research results cannot be cheap for others, so Bao Zixuan began to work at MIT.

The library carefully prepares graduation thesis.

Although he understands all the working principles and technical features, regarding the three-rotor engine, the most complex machine in the world, Bao Zixuan cannot write the entire industrial production process alone, let alone manufacture it.

It is a system engineering that requires materials, aerodynamics, mechanical processing and other disciplines to cooperate with it. Bao Zixuan can only write out the concepts and working principles now, and this is enough.

The rest requires the cooperation of other engineers and the use of Soviet material science. Bao Zixuan is already preparing to go to Inner Mongolia, Jiangxi, Guangdong and Sichuan to purchase rare earth mineral deposits as soon as China agrees to the entry of Hong Kong capital.

, but it can’t be cheaper for rb, Korean and American companies. These are industrial gold. It seems that you can ask Mr. Huo to introduce it in advance, otherwise there is really no way.

Once rare earth resources are available, combined with Soviet titanium alloy processing technology, then the basic conditions for aircraft manufacturing have been solved, and all that is left 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 needs to print three copies of his thesis, one will be sent to the Massachusetts Institute of Technology for review, one will be sent to the University of Oxford in the UK, and one will be kept by himself for his defense.
