Chapter 786

Aeroengines are now an important industry of Dongsheng Heavy Industry.

Aviation engines are different from ordinary engines - once the aircraft flies into the air, once the engine fails, it will be a big deal.

Therefore, the manufacture of a new aero engine requires far more rigorous testing than ordinary engines.

Before a new engine is put into use, it needs to go through indoor test bench, open-air test bench, high-altitude simulation test bench, aerial test bench...

It has to go through a series of rigorous tests such as swallowing birds and ice.

Overhauled aero engines also need to be tested for normal operation.

Dongsheng Heavy Industry currently only has an indoor test bench for limited testing.

The previous turbofan-20 engine with a large bypass ratio and the "Yellow River" engine with a small bypass ratio were all tested by the military itself.

The piston-type heavy oil aircraft engine was tested by Dongsheng Heavy Industry in Austria.

Moreover, compared with the turbofan engine, the power of the piston type heavy oil aeroengine is relatively small, and it is currently only applied for use in drones, and the test is relatively simple.

At present, there are no sound regulations in China to follow. We can only get foreign tests, and then rely on foreign standards to force the country.

Fortunately, the Chang'an branch is focused on small bypass than military engines.

But the Shanghai company cannot always rely on the military, let alone foreigners.

They have to perfect their testing system.

The air test bench needs to fly a real aircraft to the sky for testing. The air test bench in our country used to be the H-6. In the past two years, an Il-76 was introduced from the Russian Gromov Test Flight Academy.

The high-altitude simulation test bench has too much investment and too high technical requirements.

Neither of these two test benches can be done in a short while.

What Dongsheng Heavy Industry urgently needs now is an open-air test bench for benchmark performance tests, environmental adaptability tests, swallowing tests, noise measurements, emission measurements, attitude tests, gyro tests, etc.

Shanghai does not allow the construction of open-air test benches.

In the 80s, Shanghai spent huge sums of money to build an open-air test bench for aero-engines with a maximum thrust of 150 kN.

However, due to the noise disturbance during the test, residents complained repeatedly, and finally had to be abandoned.

The open-air test bench cannot be placed on the seaside or on an island. Excessive wind will affect the test results.

It can't be built at too high a place, too high altitude will affect the test results.

The open-air test bench should be constructed in an area close to the standard atmospheric conditions, and the altitude should preferably be below 130 meters.

Cannot be built in the desert, wind and sand will corrode the engine.

It can't be built too far. A new aero engine needs to go through thousands of hours to tens of thousands of hours of testing before it succeeds.

It would be too much trouble if the engine had to be transported one or two thousand kilometers away for each test.

To put it bluntly, several cities around Shanghai are the most suitable.

In addition, housing prices and industrial land prices in Shanghai have become more and more expensive in recent years, and Dongsheng Heavy Industry is also planning to transfer some industries out.

It just so happens that several cities around Shanghai are also very willing to accept this kind of industrial transfer.

After preliminary investigation, Dongsheng Heavy Industry finally selected Nanjiang Xuzhou.

"In the past two years, housing prices in Shanghai have been soaring! A square meter seems to be going up to [-] yuan. Last time I calculated, those newly recruited workers will have to buy a house for more than ten years!" Wang said. The vice president complained.

"Ten years is not bad!" Yang Dongsheng smiled.

The income of Dongsheng Heavy Industry in the industry is considered high, and the front-line workers are higher than the white-collar workers of many foreign companies.

If you enter Fu Xkang, you may not be able to afford a house for the rest of your life.

"I didn't get married until I was in my [-]s, and I'm almost [-] after giving birth to a child. How can I have prenatal and postnatal care?" Vice President Wang shook his head again and again.

When Vice President Wang and his parents first started working, the house was assigned, the partner was introduced by someone, and the medical treatment was reimbursed by the state.

Naturally, I can't imagine what it would be like to spend six wallets for the down payment in order to buy a house, and then spend the next few decades of life on it.

At this moment, Xiao Li's cell phone rang.

After Xiao Li took the phone, after listening to a few words, he turned around and said to Yang Dongsheng, "Mr. Yang, he is from Dongsheng Institute of Technology!"

Calculating the time, it should be time to enroll students. Yang Dongsheng reached out to Xiao Li.

After receiving the phone, Yang Dongsheng said impatiently after listening to a few words, "I repeat, Dongsheng Institute of Technology does not want special sports admissions! What kind of football team do you want? No matter how fast people run, can they outrun cars?"

Every time it comes to the Asian Cup or the World Cup, a bunch of people in China will jump out and say that there are more than one billion people in China, but they can't find eleven who can play football.

Yang Dongsheng is very thankful that our country's football is not good, because it shows that the next generation of our country does not need to rely on sports to achieve class transition.

Let's look at the countries that play football well, not to mention backward regions like South America and Africa.

Europe and the United States are not much better, their class has solidified.

Private elite schools in Europe and the United States have a high enrollment rate, but the tuition fees are skyrocketing.

The tuition fees of public schools are cheap, and they implement the happy education that many education experts respect, but they cannot be admitted to good schools.

Children from the bottom of the class, if they want to achieve a class transition, they can only work hard at sports-entertainment needs to be praised.

So many people ran to play football, so naturally they played well.

Europe and the United States can also alleviate the contradictions of class solidification by absorbing immigrants and wealth from all over the world.

If the children of our country can only achieve class transition by playing football, they will not be far from subjugation!
After driving for more than an hour, the car finally arrived in Xuzhou.

I met the leaders of Xuzhou first.

Everyone introduced them one by one. When Xuzhou introduced a middle-aged man who looked to be in his fifties, he said, "This is Director Xu!"

Yang Dongsheng was taken aback when he heard the words. Xuzhou's surname was Xu, it was not easy.

Such a big matter in the previous life has been stabbed until XX, and I vowed that I will deal with it seriously, but in the end it still doesn't matter.

It can be seen that these people are powerful!
Yang Dongsheng looked Director Xu up and down, "I heard that Ling Qianjin has returned from studying in the United States?"

"Yes!"

"It is said that he changed his name, took the special XX channel, and settled in Shanghai?"

"President Yang knows my daughter?" Director Xu asked.

"It's not just acquaintances, I've admired you for a long time!" Yang Dongsheng saluted with fists in his hands.

"Do you want to report my daughter's changed name?"

"You don't need this, do you? You can find it by searching the Internet!" Yang Dongsheng said.

In the morning, there was a symposium, and in the afternoon, I went to see the place designated for them to build an open-air test bench.

In order not to disturb the people, the open-air test benches of General Electric and Pratt & Whitney both cover an area of ​​tens of square kilometers, but Dongsheng Heavy Industry does not have this condition.

This piece of land is located in the south of Xuzhou, and it can be seen that it should have been a cement factory.

The factory faces the lake on one side and a low hill on the other.

The mountains were dug in a mess, and these mountains were presumably used as raw materials for the cement factory.
