Chapter 592 Hehe (first update)
But before that, Liu Hai still has one extremely important thing to do.

That is to establish a more professional and larger jet engine test site.

The turboprop engines currently manufactured by Liu Hai are not very large. If larger turboprop engines are to be manufactured in the future, a more professional testing site will be needed.

And it cannot be tested indoors like now, because the current turboprop engines are not large.

The dry weight of each turboprop engine currently in use is only a few hundred kilograms.

More jet engines will be developed later, so professional testing grounds are also needed.

As an aircraft practitioner, Liu Hai certainly has a clear understanding of the test site and the equipment involved.

This kind of testing is usually done in a safe area.

Liu Hai picked up his pen and started writing the plan for the test site. The jet engine test site needs to be equipped with a variety of equipment to ensure the performance and safety of the engine.

The first is the engine bench, which is used to install and test the engine, and the exhaust ejector is used to discharge engine exhaust gas.

A sensor system used to measure the thrust produced by an engine.

Someone once got sucked in, and then there was a pile of minced meat behind.

In addition, it is also anti-collision. It seems that there is a laboratory behind Europe, which makes it a joke.

Sensor system used to monitor engine operating status and other parameters.

This is also divided into levels. Different engines are tested according to different levels. It can be said that its importance in the aircraft engine manufacturing process is lower than that of the wind tunnel.

Some people say that even if it rains heavily, it is impossible to spray tons of water every second.

Everyone should know that the compressor fan in front of the jet engine has great suction power.

Water resistance means that water can be sprayed directly at the engine fan port, directly spraying several tons of water per second.

Infrastructure for installing and securing test equipment.

Coupled with the speed of the jet engine and the range of its suction, there is a lot of water in the maximum rainstorm.

Fuel system, including fuel tank, fuel pump, oil filter, etc.

During the test, not only the performance of the aircraft engine itself was tested, but also the waterproofness, impact resistance, and lightning protection were tested.

Communication systems and monitoring systems for monitoring the test process and data analysis, as well as command systems.

Measuring system for measuring the flow of fuel.

The power system provides power support for the test site, and there must be sufficient safety measures to ensure that the power can be cut off at any time.

Monitoring test system for measuring and monitoring various parameters of the engine.

In order to test the safety of aircraft engines in heavy rain weather.

A companion tool system for maintaining and testing equipment.

Collection module for collecting and processing test data.

By the time Liu Hai crosses over, the number of sites around the world where large jet engines can be tested can be counted on one hand.

It is also equipped with rescue systems, such as fire protection systems and medical rescue systems.

When European and North American aircraft laboratories conducted anti-collision experiments, the two came to completely different conclusions.

They used chicken simulated birds sold in supermarkets to hit the aircraft engine. Every test in North America was successful, but it seemed that it failed several times in Europe. In the end, senior engineers from North American laboratories were bribed privately.

The senior engineer looked at their experimental process and seemed to have asked them for a large sum of money. The final solution was to let them defrost the chicken and then test it.

The European jet engine laboratory directly used frozen hard machines from supermarkets for testing, and the engines were damaged every time.

There is also lightning protection, which I won’t mention.

Therefore, a professional jet engine testing ground must be established.

Liu Hai writes and draws in the notebook. Of course, there are some things that Liu Hai cannot realize now, such as the real-time high-definition dynamic monitoring system when Liu Hai travels through, as well as the intelligent fire protection system and intelligent alarm system.

The intelligent fire protection system is to install automatic fire water cannons at the test site.

Of course, the water sprayed out of this water cannon is not necessarily water, it may be various fire-fighting foams or water-based fire-extinguishing materials.

Therefore, this kind of testing system is usually in a separate area, and usually in a valley, because it is convenient to collect contaminated water. Once a major accident or leak occurs, these things will not spread easily.

Even if some fuel leakage occurs, it can be controlled in a small area.

A dam will also be built in the valley. The water from the dam can not only be used to extinguish fires, but also to intercept polluted water.

These are lessons learned, testing things like aircraft engines is dangerous.

After all, with such a high speed, if there is even the slightest problem, the entire experiment may explode.

Of course, compared to rocket engine testing, jet engine testing is much safer.

As for transport aircraft, Liu Hai still plans to copy the C130.

The Greyhound transport aircraft uses a T56-A-452 engine with a blade diameter of 4.11 meters and 4910 shaft horsepower.

C130采用的是T56-A-15，单台推力4200轴马力，桨叶直径4.1米。

The maximum payload of the Greyhound transport aircraft is 4.5 tons and the maximum payload of the C130 is 19.8 tons.

In 2020, although the C130 transport aircraft is at the bottom of the rankings, it does not prevent it from being the most successful tactical transport aircraft.

As a tactical transport aircraft, it is the most successful, longest-serving and most produced active transport aircraft in the history of Bald Eagle aviation.

Liu Hai also wants to redesign a large aircraft of our own country, but having said that, instead of copying these classic designs, he has to work hard to create another design. Liu Hai feels that he is not an idiot. Although Liu Hai also wants to independently design and manufacture a transport aircraft belonging to our own country from the bottom of his heart.

But the current domestic scientific research and design environment does not have such conditions at all.

Liu Hai feels that if he were to work alone, it would take at least 5 to 10 years to complete this project.

And it doesn’t mean that you think a successful design is successful, just like when the bangs crossed, the famous 737max, you say it is successful or not, this is the design that the company thinks is the most successful, but in fact?

Moreover, Liu Hai feels that in 5 to 10 years, he doesn’t know how much equipment he can copy.

Liu Hai felt that when he finished copying what he wanted to copy, the domestic scientific research environment would be better, and then he would be able to design and build his own aircraft.

However, Liu Hai found it very difficult, because for old aircraft, especially transport aircraft, Liu Hai admitted that Big Brother Next Door is the best.

Regardless of whether it is a transport aircraft of any level, the largest aircraft is the An-225, as well as the An-124 and Figure 160.

It crushes other countries in the world at any level, so Liu Hai feels that instead of working hard on the design for 5 to 10 years, it is better to plan early to poach Big Brother's corner.

Now let’s design based on the bald eagle next door, and then wait about 10 years before we can follow the big brother next door.

I believe that with another 10 years of development, when Big Brother collapses in the future, we can also reach out and do something.

To be honest, my bangs were a bit slapping my thighs when I traveled through time in my previous life. When Big Brother died, we couldn’t sit at the table and share the cake due to various reasons.

But we benefited a lot later, but it was a pity that Fat Goose's younger brother, who had a good relationship with us, ended up like what he did later.

"Yingzi, I'm sorry, who made my aircraft carrier space your best aircraft carrier? Even if I want to copy it, others can't copy it." As for Liu Hai, does he feel guilty for copying these things?
Of course, if there is no field of military equipment, it would be something everyone can copy if they show their special abilities.

"Look for an opportunity to learn nuclear power!" Liu Hai plans to start learning nuclear power.

The Bald Eagle's first-generation nuclear-powered aircraft carrier USS Enterprise uses eight nuclear submarine reactors, but the combined equipment of the eight reactor stacks allowed Enterprise to reach the Guinness World Record for the longest aircraft carrier in the world.

The combined power of the Enterprise's eight reactors. Only 8 horsepower.

The single Ford in the Liuhai aircraft carrier space can reach 28 horsepower, and the total horsepower of the Ford reaches 56 horsepower.

While Liu Hai was writing about the construction plan of the jet engine test site, he began to conceive of the subsequent development in his mind.

"Xiao Liu." Sun Aiguo has been walking a little wobbly recently. Our country's self-designed and self-made jet transport aircraft has begun mass production. What does this mean? As a senior factory director, Sun Aiguo certainly understands.

The name of the factory mentioned by the superiors is Dongfang Heavy Industries, which means that the factory will not be split up in the future.

In fact, the superior leaders were originally going to write the words "China Heavy Industries", but then they thought that China can only be in our country, but the East is different. The East in the world is a very large area.

In other words, superior leaders hope that the motorcycle factory will become the dazzling pearl of the East, not just China.

"The leader is here?" Liu Hai got up and poured tea for Sun Aiguo.

"Are you busy?" Sun Aiguo asked while sitting down while looking at Liu Hai writing.

"With the development of our country's aviation engines, I feel that a more professional testing venue is needed. I will make a plan based on my experience, and the leaders will make corrections when the time comes." Liu Hai nodded and explained, but as an aviation expert, Liu Hai Expert, no one can refute your plan, because he is the authority, but you still have to be modest.

"Just submit it to me. When the time comes, you will supervise and supervise the construction in our factory. No one in our country will refute what you come up with, and no one has a reason to refute." Sun Aiguo took Liu Hai and turned it upside down. of warm water, and said.

"Leader, I admit that my level is very high, but one person is responsible for the shortcomings, and three people are responsible for the strengths. When the time comes, we still have to brainstorm, check for omissions, and try our best to do our best." Liu Hai will not encourage this kind of trend and feels that he is the authority. , others cannot change their own things, but often what some people think is authoritative turns out to be false.

For example, when Liu Hai crossed over, it was about burning straw. In most developed countries around the world, straw was burned in the ground, including small books, but some people had to take out something to enlarge it in order to attract attention.

Of course, straw burning should be done in a planned and scientific way, rather than everyone just burning it all at once, causing various accidents.

It is definitely wrong to burn straw indiscriminately, because in the Central Plains some people harvested wheat in front of them, and they burned it. As a result, they also burned the unharvested wheat next door.

There are also some people in the southwest who burn straw and do not create certain isolation zones to cause wildfires.

There is no absolute right or wrong in terms of something. It should be formulated based on the actual situation, which is more in line with our domestic policies, rather than saying that one size fits all.

Of course, one size fits all, this won't matter.

"Okay, then I will ask the superior department to hold an expert meeting to discuss. Do you have any new plans to build a larger and more professional engine testing site?" Sun Aiguo nodded when he heard what Liu Hai said, and then asked.

"I'm going to imitate the C130." Liu Hai chuckled.

"So the next step is to ask the leader to help me collect various information about the C130. I just need some public photos and data. Then I will make a model first and take it to the wind laboratory for testing."

When Sun Aiguo heard this, he asked, "Didn't you plan to design and manufacture it independently before?"

"That is too difficult. I can solve the power system, but the design of the entire aircraft involves all aspects. The main reason is that there is a shortage of talents in this area in China. I estimate that it will take 10 years to complete."

"Now I will first solve the problems we have in our country, and in the process lead a group of people to learn. This group of people can learn for five or six years. Then maybe it will be faster for us to design new aircraft." Liu Hai said explain.

"Everything is according to your wishes. We do need a tactical transport aircraft. The carrying capacity of the twin-engine turboprop transport aircraft is indeed a bit small." Sun Aiguo understood what Liu Hai said, that is, the current domestic scientific research and technology level cannot keep up with Liu Hai's. level.

Immediately afterwards, Sun Aiguo said: "There is also great good news this time."

"Our utility helicopters and armed helicopters stole the show at the Gallic Air Show, but other countries simply don't believe that these two helicopters were produced by us."

"And the shameless Gallic Chicken did not come out to refute other countries' claims. Instead, he felt proud that they could also manufacture these two aircraft."

"It seems that we are only supporting these two helicopters, but we have not made any public clarification here. After all, the Gallic Chicken people still have a lot of face."

"And recently the Third Master is about to make a move. You really hit the mark. We were prepared last year for where the Third Master chose to cause trouble. Unexpectedly, the Third Master gave us an extra year. Moreover, the Third Master's 1000 T62s are only available now. 250 units are capable of action, and of course they still have T55/56. We estimate that they will take action when the dry season comes. "

"We won't take action directly, right?" Liu Hai asked after hearing this.

"How is that possible? They are the king's national defense army, and they also use Big Brother's weapons and equipment."

"Some of Big Brother's weapons and equipment are sold privately from the third master's house, and they even have the original packaging of Big Brother. Their officers are just like the warlords in our country before. What they send from above cannot reach the soldiers below. The middle part of his hand was sold by the officer." When Sun Aiguo said this, the corners of his mouth almost burst into tears.

Liu Hai could imagine that after the third master was beaten violently by the National Protector Army, he was probably a little confused when he saw the equipment used to beat him, and he also laughed.
