Chapter 267: Engine Boosting Technology
The news that the Ministry of Education wants to engage in business soon spread, and there have never been state-owned enterprises in East China before, but now the Ministry of Education wants to engage in enterprises, which is basically the first batch of state-owned enterprises after the establishment of the empire.
This is completely a state-owned enterprise in disguise.
The only difference is that the Ministry of Education does not involve those industries that are too profitable, but from the perspective of education spending.
In addition, it is also a company set up to provide an internship environment for students, and the enterprises of the Ministry of Education will recruit a large number of interns.
However, the advantages of the Ministry of Education are also obvious, that is, there are many talents, and they are all enterprising young people, and major universities are also engaged in scientific research, so they also have advantages in technology.
The Ministry of Education can be one step ahead of others in this new industry by seeing some potential industries.
Students also often engage in technological inventions, which can be described as a precursor to enterprises in the Ministry of Education.
The first step of the Ministry of Education aimed at the vegetable market, and at this time, the technology of planting vegetables in the greenhouse out of season was not yet popular, and this technology happened to be in the hands of agricultural universities.
As soon as Zhang Taiyan's idea was passed on, the students selected from the following business management colleges and universities immediately realized the value.
First of all, this vegetable sales platform, can attract customers through cheap and multi-selling, the reason why you can sell vegetables at a low price is to cut off those small vendors, those small vendors can't sell much vegetables a day, their personal output value is very low, and they want to increase their personal output value, they can only increase the price of vegetables, which undoubtedly brings a burden to the citizens. If the profits of ten or twenty small vendors are concentrated on one sales platform, or even more, then the profits are considerable.
Although it is cheap and expensive, it does not make much money, but it is worth it on this platform, and the Ministry of Education can develop special breeding, raise some wild boars and other such gimmicky things, or what special breeding varieties such as Wang Ba and pheasant, and then sell these special breeding agricultural products through this platform.
If there is a concept of 'organic vegetables' in this era, you can move in, but there are out-of-season vegetables.
To set up such an agricultural product sales platform, first of all, there must be enough funds to form a scale, otherwise there will be no profits, and then a perfect cargo allocation system is needed, as well as a good image of the platform itself.
The student group responsible for planning soon came up with a perfect planning plan, and the sales platform can play the slogan of 'the same food safety testing as the school', and put the school's food safety testing system on the sales platform, and the relevant food testing departments to form a double test, in order to gain the trust of consumers, and now people know that the school's food safety testing is the most stringent in China.
In terms of service, you must be smiling and welcoming, and the employees who buy groceries can choose high-quality graduates from those low-end schools to take on the role.
In the supply of vegetables, you can build vegetable planting bases in various places, with the Ministry of Education can use funds and talents, technical advantages, the development of vegetable planting bases is very simple, it is very easy to beat competitors, and can even evolve into a monopoly system of vegetable supply.
After the plan was submitted to the Bank of East China, the Bank immediately released 100 million yuan to the Ministry of Education.
As soon as the Ministry of Education got into business, it was really amazing, and soon the Ministry of Education set up a foundation to provide funds for those students to start their own businesses.
If students have any good entrepreneurial ideas, then they can find a foundation, and if the foundation thinks the idea is feasible, it will give money to help start a business.
It's certainly not a free lunch, and the Foundation is going to have a stake.
There are also such foundations in East China Group, Zhongsheng and Huasheng Group, and those young people who want to start a business can try their luck with these foundations, and if they are valued by the foundation, funds are not a problem.
At present, these foundations have a common standard, that is, entrepreneurs must have national consciousness, because the foundation wants to support national capital businessmen.
The existence of these foundations can help many young people realize their dreams.
The profits of the foundation are used to continue to provide entrepreneurial funds to other entrepreneurs, thus forming a cycle of good surnames.
Whether the foundation can make a profit mainly depends on the strength of the gatekeepers, but sometimes it seems that the idea is not very potential, and the foundation will also give some money for young people to try. It's good to succeed, but it's not a big deal not to succeed. It would be a mistake for the Foundation to be a for-profit organization if it is to make a profit, and the purpose of the Foundation is to help young people achieve their dreams.
At this time, the empire's commercial system was relatively perfect, and the number of foundations like this was still increasing.
The Ministry of Education's foundation is just one of them, but it has a great deal of significance, and it provides a path to heaven for many students.
When the occupation of capital in various fields reaches a certain level, it is the era when creativity is king, the times are changing, new needs and problems are also increasing, as long as we can adapt to the development of the times, come up with good ideas, meet the market demand, and solve the problem, then not only entrepreneurs can make money, but also a supplement to the social system.
The Ministry of Education provides funds for students to start their own businesses, and after these students succeed in starting their own businesses, they will also give back to the education system to thank the school for nurturing them.
At this time, there were many businessmen, although they did not come out of school, but they were also keen on education and often donated money to schools in their hometowns.
China's business has gradually become its own system, no longer lagging behind Europe and the United States and other countries, and many business ideas are more advanced than those of Europe and the United States.
However, creativity is a thing that can be copied in addition to one's own thoughts, and business ideas between countries are often copied and copied. If you see a good project in another country today, you can learn it, and tomorrow you will see it again and continue to study.
The state-owned enterprise model of the Ministry of Education belongs to a model that can operate more healthily, first of all, it is a new system, there are no stereotypes, and then the main employees in the future are students, these students can bravely pick out the existence of various problems, and young people are always not lacking in enthusiasm and enthusiasm, as long as the problems are seen above, they will be solved, and it is difficult to form any dark corners.
Moreover, there is no bureaucracy in such state-owned enterprises, because the enterprises of the Ministry of Education do not have policy advantages, and if they want to survive in the market, they must be able to withstand market competition.
The Ministry of Education's engagement in business has also attracted widespread attention in society, but many people have a wait-and-see attitude towards the Ministry of Education's involvement in business, some in favor and some against.
Opponents argue that money cannot be allowed to disrupt the education system.
However, this problem is considered by the Ministry of Education, and basically it will not disrupt the normal order of education.
…… Imperial Academy of Science and Technology, Engine Research Group, this is a research group with sixteen researchers, and the leader of the research team is named Zhou Chunhai.
The Imperial Academy of Science was formerly known as the East China Academy of Science and Technology, but it was just a different brand.
The institute is home to some of China's most high-end scientific researchers, and although it seems that there are still very few personnel, the engine research team has made great breakthroughs recently.
"Team leader, the supercharged engine is ready for inspection." Deputy team leader Su Jinwen said to Zhou Chunhai.
"Has the heat dissipation problem been solved?" Zhou Chunhai asked.
Su Jinwen said: "The heat dissipation group has solved the problem of heat dissipation, and the supercharger uses coolant cooling, and there is no problem in heat dissipation. ”
"Okay, let's start the inspection right away." Zhou Chunhai said excitedly.
Su Jinwen nodded, and soon an aircraft engine was lifted up, and after it started, the engine began to run.
The engine that just runs is no different from an ordinary engine, Su Jinwen said: "This exhaust gas turbocharging technology needs the engine to run fast in order to have a supercharging effect, the faster it turns, the higher the supercharging, but usually if the aircraft is driving at low speed, it is not very easy to use, and there are some lag surnames, if we combine mechanical supercharging with turbocharging, use mechanical supercharging at low speeds, and turbocharging at high speeds, we can solve this problem." ”
"It's a good idea, but this complex booster system can be a little complicated." Zhou Chunhai nodded, "However, even if our exhaust gas boosting technology is not combined with mechanical boosting technology, it can increase the power of the aircraft engine by at least 30%, and theoretically it can even be 50% higher, but the fuel consumption is not much higher than that when it is not supercharged, that is, it increases the power and is more fuel-efficient. ”
The so-called exhaust gas boosting technology is to increase the air intake of the engine with a supercharger.
As we all know, the engine is not completely used for fuel, in terms of the current engine technology of the Chinese Empire, although it is the world's leading, but the diesel engine can only use 29% of the fuel, and 71% of the fuel is wasted.
The main reason why fuel is wasted is incomplete combustion, which is due to a lack of oxygen. In this case, a supercharger can be used to blow air into the engine.
The supercharger has no mechanical connection to the engine and is actually an air compressor that compresses air to increase the air intake. It uses the exhaust gas exhaust gas of the engine to drive the turbine in the turbine chamber, and the turbine drives the coaxial impeller, and the impeller presses the air sent by the air filter pipe to pressurize it into the cylinder. When the engine speed increases, the exhaust gas discharge speed and the speed of the wheel also increase, the impeller will compress more air into the cylinder, the pressure and density of the air can increase to burn more fuel, and the corresponding increase in fuel can increase the output power of the engine.
That is, the larger the exhaust gas, the more efficient the supercharger.
Using this principle, Zhou Chunhai and Su Jinwen led the engine research team to conduct dozens of experiments, and because the direction was correct, the results were quickly obtained.
The engine has been successfully supercharged.
However, the supercharger is installed on the exhaust side of the engine, so the working temperature of the supercharger is very high, and the speed of the rotor is very high when the supercharger is working, which can reach more than 100,000 revolutions per minute, and the temperature is so high that it can directly catch fire.
The problem of heat dissipation is not a problem that Zhou Chunhai's group specializes in, so this problem was left to other professional teams for more than a month and finally got results.
The engine spun faster and faster, making a tooth-souring spinning sound, and under the effect of the supercharger, the power of the engine skyrocketed.
"I don't know if I can pass this time." Zhou Chunhai looked at the running engine and prayed not to catch fire.
After about two minutes, the engine finally reached its maximum power, that is, the supercharger was running at its maximum speed.
Three-minute ...... Four minutes ...... Five minutes...... Six minutes ...... "It's like we've made it." Zhou Chunhai said happily, but as soon as his words fell, the supercharger that was still running suddenly 'crackled'.
Then it just stuck there, but the engine continued to run, but the speed immediately decreased.
"What's going on?"
Zhou Chunhai and Su Jinwen, as well as the researchers on the side, all widened their eyes, not understanding what was going on.
"Turn off the engine." Su Jinwen instructed the staff.
When the engine was turned off, the research team immediately surrounded it, and when they removed the supercharger for inspection, they found that the ball bearings were badly worn, and the mechanical needle rollers were broken.
"How so? It's new! Su Jinwen looked at the broken mechanical needle rollers and the badly worn ball bearings in disbelief.
"It may be that the temperature is too high, causing the metal to expand, and the speed is too high for ordinary bearings and needle rollers to withstand." Zhou Chunhai said.
"How can this be done?"
"We have to find a research group on alloys to study special bearings."
"Don't be discouraged, this is the last hurdle, as long as we solve the supercharger problem, the exhaust gas turbocharging technology will be mature." Zhou Chunhai encouraged the members of the research team.
"Team leader, we're running out of money." Su Jinwen reminded.
"Both the Army and the Air Force are very interested in supercharging technology, and our supercharging technology is mainly used in diesel engines, and the engines currently used in the Army's combat vehicles and the Air Force's aircraft are diesel engines, which is completely different from other countries." Zhou Chunhai said: "I don't have the money to go to the army and the air force, they have money." ”
"Then let's make a detailed report?"
"Definitely."
...... "Exhaust gas turbocharging technology, this thing ......" Xia Jun looked at the report submitted by the Science and Technology Research Institute below, and was startled after reading it: "The engine team has actually begun to study this kind of thing." I'll check ...... first."
Xia Jun opened the exchange platform and looked for the exhaust gas turbocharging technology, and immediately found the corresponding technology.
After reading the detailed information, Xia Jun was overjoyed, and this supercharging technology is a good way to solve the current lack of diesel engine power.
At present, most of the combat vehicles of the Chinese Army and the aircraft of the Air Force use diesel engines, but high-efficiency diesel engines only appeared in the 50s.
The diesel engine used in the Soviet tank is also a relatively backward diesel engine, but the diesel engine has many advantages, first of all, it is not easy to be frozen in cold climates, and then the diesel will not be ignited when it encounters an open flame, and the gasoline is a little bit.
In the future, if China wants to fight in the cold Siberian region, it is obviously not possible to use a gasoline engine for combat vehicles, and the diesel engine has a higher power than a gasoline engine, which is more suitable for heavy vehicles such as combat vehicles.
Engine supercharging technology, the first use of this technology in military aircraft was the United States during World War II, but the aircraft built is easy to catch fire, obviously the heat dissipation problem has not been solved.
