Chapter 486 Hard work (first update)

The cordon on the ground is a regulation within the factory. During maintenance, no other people are allowed to enter.

The main reason is that it is unclear when something goes wrong, especially for precision and sensitive equipment such as helicopters, and there are also special regulations for ground maintenance, mainly to prevent someone from sabotaging it.

Everything is easy to explain in the factory, everyone basically knows everything, and no one will run around. But once the helicopter arrives, no one can tell what will happen.

Liu Hai knew that there were problems with the wood designers in his previous life, let alone other people.

Now the responsibility lies with people. If something happens, it is your responsibility to protect it and prevent others from making excuses to shirk the responsibility.

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

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

"Leader." Liu Hai had long looked at Sun Aiguo gesturing to him.

"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, but yours is a twin-engine helicopter, but the maintenance time is shorter." The superior department leaders are divided into many departments. A leader is the leader in charge of the aviation industry, so he still knows a lot about aviation equipment.

Of course, there is not much aviation equipment in China now. By the time Liu Hai crosses over, there will be more aviation equipment. When the leader arrives, it will be impossible to know all the aviation equipment.

"The Gazelle Helicopter is just an attempt, but the normal inspection time is a bit long, and the tools are troublesome. Once the tools are missing, it will cause a major accident."

"However, the Gazelle helicopter was not designed by us. During the modification, it became four-dimensional and there are some places where it is impossible to be maintenance-free. It just means that we need to carry fewer tools and the time saved is not too obvious." Liu Hai explained.

To be maintenance-free, the fuselage frame must be designed in place, and bangs cannot be randomly cut into other people's fuselage frames, or do other things randomly.

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

If these screws are removed rashly, the vibration of the fuselage may become unbalanced.

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

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

A helicopter is something that needs to fly, and it runs at high speed, so I don’t dare to change my bangs too much.

If it were to be completely reproduced on the gazelle without maintenance, the amount of calculation would be overwhelming.

"Last time was considered an attempt." Liu Hai concluded.

Before Liu Hai could say anything else, Sun Aiguo said first: "Give our leaders some insights!"

"Right away!" Liu Hai nodded immediately when he heard Sun Aiguo say this.

The leaders of the higher-level departments next to him didn't pay attention to Sun Aiguo's words about gaining a lot of experience. He had a lot of experience in the first place.

So they moved things like auxiliary tools and ladders over, and then Liu Hai took Sun Aiguo and the superior department leaders to climb up in person to demonstrate.

"This is good!"

"In this way, you don't need to carry more tools up and down during normal inspection and maintenance, and you don't have to worry about counting the tools later." The leader of the superior department personally watched the shell of the Liuhai turboshaft engine open, and then pointed out the inspection one by one. parts.

"Comrade Xiao Liu, what do you think about armed helicopters?" The leader of the superior department suddenly asked this question.

"The leader is referring to the old American Cobra model armed helicopter?" Liu Hai asked after hearing this.

"Yes, we used to mount some weapons on ordinary helicopters, but they are still far from professional armed helicopters." The superior department leader nodded.

"I have some thoughts on this in the future, but I'm not very proficient in weapons and radar systems." Liu Hai did not hide his thoughts.

"We have cooperation with Gaul Chicken for the helicopter's radar and weapon fire control system. It's really not possible. We can jointly develop an armed helicopter. We provide the hardware facilities, and they will provide the weapons system and even weapons." The leader of the superior department said this. Bangs was startled.

When did we get so close to the Gallic Chicken?

However, at this stage, the Gallic chicken is still very strong-minded, even when the bangs are crossed, it is considered a breath of fresh air throughout Europe.

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

But this is also possible. After all, our current industrial strength is many times better than in history.

The Gallic Chicken didn't have any teammates in Europe, not to mention the Niu Niu across the sea, they were natural enemies.

As for the Eagle Sauce on the other side of the ocean, it's full of evil and abacus. During World War II, if this bastard hadn't been eating in the middle, the Gallic chicken might not have been so miserable.

As for San Dezi, his bones have been broken, and he will never be able to straighten his waist in this life.

It is impossible to cooperate with the Bear Country. After all, everyone is just making a living in Europe, so look around, who else can we cooperate with?

Of course, it's a big country in the East. Not only does it have strong industrial strength, but all of its export helicopters have been copied by the other side, not to mention that the other side will kill you eight thousand times.

"They cooperate with us in many aspects. The log transport truck we exported for the first time included them." The superior department leader seemed to notice that Liu Hai was surprised, so he explained.

"In addition, they are also the first batch of reservations for convenience medical vehicles, which are mainly used at bases in West Africa." The leader of the superior department added.

Liu Hai nodded when he heard this: "I don't have much news about Cobra gunships here."

"Feel free to express yourself. The science fiction novels you wrote are very good. Give full play to your imagination. We need people to give people and materials to give materials." The superior department leader said in a complimentary tone.

When Liu Hai heard this, he thought of a kind of helicopter, that is, the Comanche.

This is a stealth helicopter, and it looks very sci-fi.

This helicopter is the five-bladed helicopter that some internet experts despise. When some internet experts looked at our own helicopter’s five-bladed helicopter and couldn’t find anything to say about it, they said that this five-bladed helicopter was not good, and they also said so-and-so. All helicopters have four propellers.

There are also the canards of fighter jets, which have also been criticized by some Internet experts. This is not good and that is not good.

"Then I'll work hard." Liu Hai nodded.

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

"But we can produce a prototype by then. From now on, America will just copy our work." Liu Hai thought of something else.

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

Of course, we are already ahead in the field of helicopters, because it will take seven or four years for the other party to finalize its design.

We estimate that we can start mass production next year, mainly depending on the performance of the aircraft itself, as well as the attached radar, fire control system, etc.

Even if we cooperate with Gallic Chicken, it is estimated that it will take some time. After all, cooperation does not mean that it can start immediately. The early negotiations will take a lot of time.

"Okay!" The superior department leader in charge of aviation also said a good word when Liu Hai agreed.

In fact, in the eyes of these superior department leaders, Liu Hai is a genius. Not only is he a genius in mechanical manufacturing, he also has enough imagination in the scientific field.

Otherwise, it would be possible to write such a high-level science fiction novel, which would be discussed all over the world.

Although the superior department also noticed that someone was behind it, the leader of the superior department could not 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 agreed that although he agreed, he would still make the helicopter according to his own plan. After that, he would start making a simple three-axis CNC machine tool.

Three-axis CNC machine tools are now available in China, but no one has yet realized the use of microprocessor chips to realize three-axis CNC machine tools, and may still be researching.

The superior department leaders left with satisfaction.

"Xiao Liu, you should follow your plan here. Building an airplane is not a matter of a day or two." Sun Aiguo knew that Liu Hai had been preparing for this helicopter for a long time. Since the last time he made the Oryx helicopter, Liu Hai Comrades are always preparing.

"Thank you, leader!" Liu Hai smiled.

The helicopter has been undergoing ground testing in the hangar for a week. The main purpose is to observe the control status of each part of the helicopter when it is in operation. Fortunately, there are no major problems.

The flight test will officially begin in the second week. The flight test begins with taking off from the same place, flying at a relatively low altitude, and then moving forward with various actions.

Test slowly one by one, and test each item repeatedly to make sure there is no problem with the operating system.

The height is lowered at first and then gradually raised.

As for doing those cool stunts, we have to wait until the helicopter testing is completed.

The helicopter flight test in the second week went well. After all, it was copied from someone else's classic. If it was designed by oneself, there would definitely be some problems, big and small.

It took several years for the old American Black Hawk to be finalized in 1974 and officially put into service.

Most of the time, various tests are conducted to find bugs. After the bugs are found, they need to be solved, and after the bugs are solved, they need to be tested.

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

There are never shortcuts in R&D. Of course, it is precisely because of the various problems encountered by these foreign companies during R&D that they can avoid such problems when developing the same type of products later.

Of course, if the capitalists have no conscience, there is nothing they can do. For example, a certain passenger plane that has had the most accidents is because the capitalists have modified the original plane and are reluctant to spend money to develop a new aircraft.

The flight test was conducted for two consecutive weeks without any problems.

Even the pilot of the helicopter on the test flight felt a little incredible.

Because the helicopter pilot is always ready for something to happen.

Even the letters home were written. I didn’t expect the test flight to go so smoothly.

Moreover, this helicopter has great power, which is much better than those single-engine helicopters that were flown before.

"As expected of a motorcycle factory!"

"That is, the Gazelle helicopters we manufacture have a longer service life than those imported from Europe?"

"This motorcycle factory is really full of talents. It makes large airplanes and helicopters. The key is that it does it so well."

"Why hasn't there been a test flight today? It should be 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. Has the superior leader come to inspect the work?" At this moment, the person in charge of the test flight ground work hurriedly came in and said.

Everyone in the helicopter test flight project team was stunned, and then hurriedly walked outside.

When Ma Fuqiang arrived at the workshop today, he was asked to clean up first and then put on clean clothes.

Ma Fuqiang is still a little confused. Isn't the turboshaft engine going to be assembled today?

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

After arriving at the place, Ma Fuqiang discovered, isn't this the runway of our factory?

A yellow helicopter is parked nearby, which was produced in our own workshop.

Ma Fuqiang's heart skipped a beat. It wasn't the helicopter that had a problem. Let people like him do the repairs.

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

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

"The superior leaders came to express condolences to us today. This is the result of everyone's hard work. The superior leaders will also give us medals." The person in charge of the security department spoke.

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

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

"Leader!" Sun Aiguo and other factory leaders came up and cordially surrounded their superiors.

"Okay!" The superior leader glanced at Liu Hai among the crowd. He didn't expect that Comrade Liu was so low-key.

Because there were reporters and other entourage, the bangs were not used as a conspicuous bag.

The more achievements the bangs make, the more protection they will have for the bangs.

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

The superior leader looked at the yellow helicopter, and a worker in the assembly technical team introduced it with excitement: "Boss, the helicopter you see now is a new general-purpose helicopter independently developed and manufactured by our factory."

"The yellow color you see on the surface is a coating that protects the fuselage from contamination and also facilitates ground observation of the aircraft's test flights."

"The entire aircraft weighs five tons when empty, and its maximum take-off weight can reach nine tons. It can carry 11 soldiers."

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

Ma Fuqiang was standing next to his superior. Looking at the fat old man in front of him, he was too excited to say anything. As for what his colleagues introduced, he didn't listen to a word.

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