The cordon on the ground, this is the regulation of the factory, during maintenance, idle people are strictly forbidden to enter.

The main reason is that it is not clear when something happens, especially the sophisticated and sensitive equipment such as helicopters, and even in the maintenance of ground crew, there are special regulations, mainly to prevent people from sabotage.

Everything in the factory is easy to say, basically everyone knows the roots, and everyone will not run around, but once the helicopter arrives at the place, no one can say what will happen.

Bangs knows that there are problems with log designers in their previous lives, let alone others.

Now the responsibility lies with the person, and it is your responsibility to maintain something that happens, and it also prevents someone from making excuses to pass the buck.

Finally, when the maintenance inspection was completed on Liu Hai's side, Liu Hai signed as the main responsible person.

At this time, Sun Aiguo came here with the department leaders.

"Leadership." Liu Hai had long watched Sun Aiguo gesticulating to himself.

"I remember that the Gazelle helicopter also has maintenance-free measures, but its time is not as short as yours, it is a single-engine light helicopter, and your twin-engine helicopter has a shorter maintenance time." The leaders of the superior departments are divided into many departments, and this leader is the leader in charge of the aviation industry, so he still knows more about aviation equipment.

Of course, there is not much aviation equipment in China now, and when it comes to the passage of bangs, there will be more aviation equipment, and it is impossible for the leader to know all the aviation equipment at that time.

"Antelope helicopter, I just made an attempt, but the usual inspection time is a bit long, and the tools are still more troublesome, once the tools are missed, it will cause a major accident."

"However, the Antelope helicopter was not designed by ourselves, and when it was changed, it became four, unlike some places where there is no way to do maintenance-free, but it is said that there are fewer tools to carry, and the time saved is not too obvious." Bangs opened his mouth to explain.

Maintenance-free must be designed in place when the fuselage frame, and the bangs cannot be made in other people's fuselage frames, or do other things.

Because some fixed screws are pulled directly into the inner frame, reducing the bearing capacity of the whole body.

If you hastily remove these screws, you may cause things like unbalanced vibrations in the airframe.

So the last improvement of the Gazelle helicopter did not have much effect.

This time, the native design is maintenance-free, so naturally these situations do not exist.

The helicopter is something that is going to fly, and it is running at high speed, so the bangs dare not change it drastically.

If you completely reproduce it on Gazelle and are maintenance-free, the amount of computation is simply overwhelming.

"I guess I tried it last time." Bangs summed up at the end.

Without waiting for Liu Hai to continue to say anything, Sun Aiguo first said: "Give our leaders a long insight!" ”

"Right now!" Liu Hai heard Sun Aiguo say this, and immediately nodded.

The leaders of the higher-level departments next to him didn't care that Sun Aiguo said that he had long insight, and he was originally insightful.

So he moved things like auxiliary tools and ladders again, and then Liu Hai took Sun Aiguo and the leaders of the higher departments to climb up and demonstrate in person.

"That's good!"

"In this way, you don't need to carry more tools up and down when you usually check and maintain, and you don't have to worry about counting tools later." The leaders of the higher-level departments personally watched the shell of the bangs turboshaft engine open, and then pointed out the inspection parts one by one.

"Comrade Xiao Liu, what do you think about the helicopter gunship?" The leader of the higher-level department suddenly asked this sentence.

"The leader refers to the old American Cobra gunship?" Liu Hai asked when he heard this.

"Yes, in the past, we used to hang some weapons on ordinary helicopters, but they are still far from professional armed helicopters." The head of the higher department nodded.

"I have ideas about this in the future, but I am not very proficient in weapons and radar systems." The bangs also did not hide their thoughts.

"Helicopter radar and weapon fire control system, we have cooperation with Gallic chicken, it's really not possible, we can jointly develop a helicopter gunship, we will provide hardware facilities, they will produce weapon systems and even weapons." The words of the leader of the higher department startled Liu Hai.

When did we get so close to the Gallic chickens?

However, at this stage, the Gallic chicken is still very backbone, even until the bangs cross, it is a clear stream in the whole of Europe.

Then Liu Hai thought of the fighter he saw last time, and secretly wondered in his heart, could it be that he had increased cooperation in this regard?

However, there is also this possibility, after all, our current industrial strength is many times better than in history.

The Gallic chickens don't have a teammate in Europe, and the cows on the other side of the sea don't talk about them, they are natural enemies.

As for the eagle sauce on the other side of the ocean, the stomach is bad, and the abacus is clanging, if it weren't for this bastard eating in the middle of World War II, the Gallic chicken is estimated to be not so miserable.

As for Sandezi, his bones have been broken, and his waist is not straight in this life.

It's impossible to cooperate with the bear country, after all, everyone eats together on European territory, so looking around, who else can cooperate?

Of course, it is a big country in the East, not only has strong industrial strength, but even a few of its own helicopter exports have been directly copied by the other party, not to mention that the other party still wants your life 8,000.

"They have cooperated with us in many aspects, and they are one of the log trucks we exported for the first time." The leader of the higher department seemed to be surprised when he saw the bangs, so he explained.

"In addition, they are also the first batch of convenient medical vehicles, which are mainly used in bases in West Africa." The head of the higher department added another sentence.

Liu Hai nodded when he heard this: "I don't have a lot of news about the Cobra gunship here. ”

"Free play, the science fiction you write is very good, give full play to your imagination, we want people to give people, and materials to materials." The head of the superior department said in a praising tone.

When Liu Hai heard this, he thought of a helicopter, and that was Comanche.

It's a stealth helicopter, and it's sci-fi in appearance.

This helicopter is the five-oars that some Internet experts despise, and some Internet experts looked at our own helicopter five-oars, and couldn't find a place to say, so they said that this five-oars were not good, and said that so-and-so helicopters were all four-oars.

There are also fighter canard wings, which have also been complained about by some Internet experts, this is not good, that is not good.

"Then I'll work hard." Bangs nodded.

However, the manufacturing level of Comanche is too high, and its fuselage composite material has stealth performance, which is not available at this stage.

"But when the time comes, we can produce a prototype, and Lao Mei will copy our homework in the future." Bangs thought of a little more.

When the United States produces such a helicopter later, we will take out the prototype and slap them in the face.

Of course, now we are already ahead in the helicopter area, because it will take seven or four years for the other side to finalize it.

We estimate that we will be able to carry out mass production next year, mainly depending on the performance of the aircraft itself, as well as the attached radar, fire control system and so on.

It is estimated that it will take a while to cooperate with the Gallic chicken, after all, the cooperation does not mean that it can start immediately, and the preliminary negotiations will take a lot of time.

"Good!" The leader of the superior department in charge of aviation also said a good word when he heard Liu Hai agree.

In fact, in the eyes of these higher-level department leaders, Liu Hai is a genius.

Not only is he a genius in mechanical engineering, but he is also imaginative enough in the field of science.

Otherwise, it can write such a level of science fiction and make the whole world discuss.

Although the higher-level departments also saw that someone was behind the scenes, the leaders of the higher-level departments couldn't understand what the other party was thinking.

But if you don't understand something, stop and wait, and let the bullets fly for a while.

Liu Hai smiled slightly, and promised that although he agreed, he would make a helicopter according to his own plan, and start to make a simple three-axis CNC machine tool after he finished it.

Three-axis CNC machine tools are now available in China, but the use of microprocessor chips to achieve three-axis CNC machine tools has not yet been realized, and may still be researched.

The head of the superior department left satisfied.

"Xiao Liu, you still follow your plan, building an airplane is not a matter of one or two days." Sun Aiguo knew that Liu Hai had been preparing for this helicopter for a long time, and Comrade Liu Hai had been preparing for it since the last time he made the Little Antelope helicopter.

"Thank you, leader!" Bangs smiled.

The helicopter was tested on the ground in the hangar for a week, mainly to observe the state of control of various parts of the helicopter in the operating state, but fortunately, there was no major problem.

In the second week, the flight test will officially begin, and the flight test will start with taking off on the spot, flying at a relatively low altitude, and then moving forward with various maneuvers.

Slowly test one by one, and test each one repeatedly to make sure that the operating system is okay.

The height is lowered at first and then gradually increased.

As for doing those cool stunts, we'll have to wait until the helicopter test is complete.

The second week of helicopter flight tests went well, after all, it is a copy of other people's classics, if it is designed by yourself, there must be some problems, big and small.

It took several years for the old American Black Hawk to be finalized in seven or four years to be officially put into service.

Most of the time it's all about testing, finding bugs, finding bugs, solving bugs, and testing after solving.

Sometimes a small problem can delay for half a year, or even a year.

There is never a shortcut to R&D, of course, it is precisely because of the various problems encountered by these foreign companies in R&D that this kind of problem can be well avoided when developing the same type of products in the future.

Of course, if the capitalist has no conscience, then there is no way, for example, a passenger plane with the most accidents, that is, the capitalist changes the original plane, and is reluctant to spend money to develop a new aircraft.

Flight tests were carried out for two weeks in a row, and nothing went wrong.

Even the test flight helicopter pilot felt a little incredible.

Because helicopter pilots are ready for anything to happen at any time.

Even the family letter was written, but I didn't expect the test flight to go so smoothly.

And this helicopter is very powerful, which is much better than the single-engine helicopters that flew before.

"It's a motorcycle factory!"

"That is, the Little Antelope helicopter we make has a higher service life than those imported from Europe?"

"This motorcycle factory is really talented, and it is making big planes and helicopters, and the key is to do it so well."

"Why haven't there been test flights today? It's time for a test flight? "Two helicopter test pilots are waiting here.

According to the previous timeline, test flights are now about to begin.

"Everyone come with me, the superior leader has come to inspect the work?" At this time, the person in charge of the work of the test flight site hurriedly entered the door and spoke.

The people in the helicopter test flight project team were stunned, and then hurriedly walked outside.

Ma Fuqiang just arrived at the workshop today, and was asked to clean first, and then change into clean clothes.

Ma Fuqiang is still a little puzzled, don't you assemble the turboshaft engine today?

After changing into clean clothes, I took the bus in the factory and drove towards the far side of the factory.

After arriving at the place, Ma Fuqiang found that this is not the runway of our factory?

A yellow helicopter is parked next to it, which is produced in its own workshop.

Ma Fuqiang sighed in his heart, it won't be a problem with the helicopter, let his people repair it.

But after arriving at the place, Ma Fuqiang saw a banner.

The content on the banner stunned Ma Fuqiang, and then he was excited.

"The superior leaders came to visit us today, this is the result of everyone's efforts, and the superior leaders will also give us medals." It was the head of the security department who spoke.

At this time, Liu Hai was pulled by Sun Aiguo to receive the superior leaders in the factory.

The superior leaders came relatively low-key this time and did not get off at the factory gate.

"Leader!" Sun Aiguo and other factory leaders went up and cordially surrounded the superior leaders.

"Okay!" The superior leader glanced at the bangs in the crowd, but he didn't expect this Comrade Liu to be so low-key.

Because there are reporters and other entourage, the bangs are not used as conspicuous bags.

The more achievements that accompany the bangs, the more protection the bangs will be.

Then the group got in the car and went straight to the helicopter test site.

The superior leader looked at the yellow helicopter, and a worker in the assembly technology group was introducing in an excited tone: "Leader, the helicopter you see now is a new type of general helicopter independently developed and manufactured by our factory. ”

"The yellow color you see is a coating that protects the fuselage from contamination and also makes it easier to observe the flight of the aircraft from the ground."

"The entire aircraft has an empty weight of five tons, and the maximum take-off weight can reach nine tons, which can carry eleven soldiers."

"There are also firing windows on both sides of the plane, which can set up two multi-barreled machine guns, and the maximum flight altitude can reach 5,700 meters, and the maximum flight speed is 350 kilometers per hour."

Ma Fuqiang followed next to the superior leader, looking at the old man in front of him, he couldn't say anything excited, and as for the introduction of his colleagues, he didn't listen to a word.

"Comrades, you have worked hard!" After listening to the introduction, the superior leader climbed into the helicopter and looked inside carefully, touched everywhere, and then got off the helicopter and said to everyone.
