But before that, bangs have an extremely important thing to do.

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

Now the turboprop engine made by Bang Hai is not too large, and if a larger turboprop engine is to be built in the future, a more professional test site will be required.

And it can't be tested indoors like it is now, because turboprop engines are not big now.

The turboprop engines used today have a dry weight of only a few hundred kilograms.

More jet engines will be developed in the future, so a professional test site is also needed.

As an aircraft practitioner, Liu Hai is of course more aware of the test site, and there are many equipment involved.

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

Liu Hai picked up a pen and began to write a plan for the test site, which 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 exhaust the engine exhaust.

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

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

A thrust sensor system used to measure the thrust generated by the engine.

A measuring system for measuring the flow of fuel.

A sensor system for monitoring the operating status of the engine and other parameters.

Acquisition module for collecting and processing test data.

The power system that provides electrical support to the test site also has adequate safety measures in place to ensure that the power can be cut off at any time.

Infrastructure for mounting and fixing test equipment.

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

A system of matching tools for maintenance and testing of equipment.

It is also equipped with rescue systems, such as a fire fighting system, and a medical aid system.

By the time the bangs crossed, the number of sites in the world that could test large jet engines could be counted on one hand.

This is also graded, and different engines are tested according to different grades, which can be said to be less important in the aircraft engine manufacturing process than the status of wind tunnels.

In the process of testing, it is necessary to test not only the performance of the aircraft engine itself, but also the waterproofness, impact resistance and lightning protection.

Water resistance means the degree to which water is sprayed directly into the engine fan mouth, directly how many tons of water per second.

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

Someone has to say that it is impossible to spray many tons of water per second in a heavy rain.

You should know that the compressor fan in front of the jet engine has a lot of suction power.

Someone used to be sucked in, and then it was a pile of minced meat.

Combined with the speed of the jet engine, and the range of its inhalation, the maximum rainfall of water is quite a lot.

In addition, there is anti-collision, as if there is a laboratory behind Europe, and it is a joke.

When aircraft laboratories in Europe and North America conducted crash avoidance experiments, the two came to very different conclusions.

It is to use chickens sold in supermarkets to simulate birds hitting aircraft engines, and every test in North America has been successful, but it seems to have failed several times in Europe, and finally the senior engineers of the North American laboratory were privately bought.

The senior engineer looked at their experimental process and seemed to ask them for a large sum of money, and the final solution was to let them thaw the chickens and then come back to the test.

The jet engine laboratory in Europe directly took the frozen hard machine in the supermarket for testing, and each time the engine was broken.

In addition, there is lightning protection, so let's not talk about this.

Therefore, a professional jet engine test site must be established.

Bangs are written and drawn on the book,Of course, there are some things that bangs can't be realized now,For example, the real-time high-definition dynamic monitoring system when the bangs cross,There is also an intelligent fire protection system,Intelligent alarm system。

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

Of course, the water cannon is not necessarily sprayed with water, it may be a variety of fire-fighting foam or water-based fire-fighting materials.

So this kind of test system is usually in a separate area, and it is usually in the valley, because it is convenient to collect contaminated water, which is not easy to spread in the event of a major accident or leakage.

Even if it causes some fuel leaks, it can be contained in a small area.

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

These are lessons learned, and testing these things with aero engines is dangerous.

After all, with such a high rotational speed, once there is a slight problem, maybe the whole experiment will blow up.

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

As for the transport plane, the bangs are still ready to copy the C130,

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

The C130 uses T56-A-15, with a single thrust of 4200 shaft horsepower and a blade diameter of 4.1 meters.

The maximum payload of the Greyhound 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 ranking, 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.

Bangs also wanted to redesign a big plane in our own country, but then again, these classic designs were not copied, but had to go to great lengths to make other designs, and Bangs felt that he was not a fool.

Although from the bottom of my heart, Liu Hai also wants to independently design and manufacture a transport aircraft belonging to our own country.

However, in the current domestic scientific research and design environment, there are no such conditions.

Liu Hai felt that if he was alone, it would take at least 5~10 years to get this project out.

And it's not that you think that a successful design is a success, just like when the bangs are crossed, the famous 737max, you say that it is not successful, this is what the company thinks is the most successful design, but in fact?

And Liu Hai feels that there are 5~10 years, and he doesn't know how much equipment he can copy.

Liu Hai felt that when he finished copying what he was going to copy, the domestic scientific research environment would be good at that time, and then he would come to meet his own independent design and build his own aircraft.

However, Liu Haijue is very difficult, because for the old plane, especially the transport plane, Liu Hai admits that the big brother next door is the best.

Regardless of the class of transport aircraft, the largest An-225 aircraft, there are also An-124, Tu-160.

No matter from any level, he crushes other countries in the world, so Liu Hai feels that instead of working hard to design for 5~10 years, it is better to plan early to dig the corner of Big Brother when the time comes.

Now I will touch the bald eagle next door to do the design, and then I can wait about 10 years to touch 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 in and take care of something.

To be honest, in my previous life, I slapped my thighs a little when my bangs crossed, and when Big Brother was not good back then, we couldn't sit on the table and share this cake for various reasons.

But we also benefited a lot later, but it's a pity that the younger brother of the fat goose had a good relationship with us, but it ended up like the back.

"Eagle, I'm sorry, who made my aircraft carrier space your best aircraft carrier, I just can't copy it if I want to." As for the bangs, do you feel guilty about copying these things?

Of course, there is no field of military equipment, that is, as long as they can copy it.

"I'm looking for a chance to learn nuclear power!" When are bangs going to start learning nuclear power.

The Bald Eagle first-generation nuclear-powered aircraft carrier Enterprise uses the reactors of eight nuclear submarines, but the combination of various equipment of the eight reactors has allowed the Enterprise to reach the Guinness World Record for the world's longest aircraft carrier.

The combined power of the 8 reactors of the Enterprise. Only 286,000 horsepower.

The Ford in the space of the bangs aircraft carrier can reach 280,000 horsepower alone, and the total horsepower of the Ford reaches 560,000 horsepower.

While bangs were writing about the construction plan of the jet engine test site, he began to think about the future development in his head.

"Xiao Liu." Sun Aiguo has been a little fluctuating when he walks recently, and my country's self-designed and self-manufactured jet transport aircraft have begun mass production, what does this mean? As a senior factory director, Sun Aiguo certainly understands.

The name of the factory mentioned by the superior leader is Dongfang Heavy Industry, which means that the factory will not be split in the future.

In fact, the superior leaders were originally going to write a few words about Huaxia Heavy Industry, but then I thought that Huaxia can only be our country, but the East is different, and the East of the world is a large area.

In other words, the superior leaders expect the motorcycle factory to become a dazzling pearl in the East, not just in China.

"The leader is here?" Liu Hai was about to get up and pour tea for Sun Aiguo.

"You're busy!" Sun Aiguo looked at Liu Hai writing something, and asked as he sat down.

"With the development of aero engines in our country, I feel that a more professional test site is needed, and I will make a plan based on my experience, and I will have to lead the correction when the time comes." Liu Hai nodded and explained, but Liu Hai is an expert in aviation, and no one can refute your plan, because he is the authority, but he still has to be modest.

"You just submit it to me, when the time comes, we will build in the factory, you should supervise and supervise, no one will refute what you take out in our country, and no one has reason to refute." Sun Aiguo took the warm water that his bangs were upside down and said.

"Leader, I admit that my level is very high, but one person is short, three people are long, when the time comes, we still have to brainstorm, check and fill in the gaps, and try to do the best." Bangs don't contribute to this kind of atmosphere, if you feel that you are an authority, others can't change your own things, but often some people think that the things that are authoritative are later proven to be fake.

For example, when the bangs are crossed, the straw is burned in the ground, including small books, but some people have to take out something to enlarge it in order to attract attention.

Of course, the burning of straw should be planned and scientifically burned, not that everyone burned it in a nest of wind, and then caused various accidents.

It is certainly not right to burn straw indiscriminately, because some people in the Central Plains have harvested wheat in front of them, and he burns them, and as a result, he also burns the wheat that has not been harvested next door.

There are also mountain fires caused by some people in the southwest who burn straw and do not have a certain separation zone.

There is no absolute right or wrong in a simple matter, and it should be formulated according to the actual situation, which is more in line with our domestic policies, rather than saying one size fits all.

Of course, one size fits all, this will not be a big deal.

"Okay, when the time comes, I will ask the higher departments to hold an expert meeting to discuss, you want to build a larger and more professional engine test site, is there any new plan?" Sun Aiguo nodded when he heard Liu Hai say this, and then asked.

"I'm going to make a copy of the C130." Bangs smiled.

"So the next step is to ask the leader to help me collect some C130 materials, just need some public photos and data, and then I will make a model 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 separately before?" ”

"That's too difficult, I can solve the power system, but the design of the entire aircraft is related to all aspects, mainly because there is a shortage of domestic talents in this area, and I estimate that it will take 10 years to complete."

"Now I will first solve the problems that we have in China, and in the process lead a group of people to learn, this group of people can learn for five or six years, then we may be able to design a new aircraft faster." Bangs opened his mouth to explain.

"Everything is according to yours, we do need a tactical transport aircraft, and 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 a major good news this time. ”

"Our utility helicopters and gunships are in the limelight at the Gallic Chicken Air Show, but other countries don't believe that these two helicopters are produced by us."

"And the shameless Gallic chicken did not come out to refute the claims of other countries, but proudly felt that they could also make these two planes."

"It seems that these two helicopters, we are only auxiliary, but we have not publicly clarified on our side, after all, the people of Gallic chickens are still very face-saving."

"And recently the three masters are ready to move, and you really said it, the three masters chose to do things, we were prepared last year, but I didn't expect the three masters to give us an extra year, and the three masters 1000 T62 are now only 250 can act, of course, they also have T55/56, we estimate that they will do it when the dry season comes."

"We're not going to do it directly, are we??" Bangs asked when he heard this.

"How is it possible, it is the king's protector army, and it is also using the weapons and equipment of the big brother."

"Some of the big brother's weapons and equipment are still sold privately from the three masters, and even the original packaging of the big brother, and the officers on their side are like the previous warlords in our country, and they can't get something out of the hands of the soldiers below at all, and they are sold by the officers in the middle." When Sun Aiguo said this, the corners of his mouth were about to crack.

Liu Hai could think that after the three masters were violently beaten by the Protector Army, he was probably a little confused when he saw his own equipment, and he also smiled.
