It stands to reason that these systems should be provided by the unit providing the system before they are assembled, but there is no way, this is all manufactured by the motorcycle factory itself.

Liu Hai is ready to end this large aircraft manufacturing, so let the motorcycle factory side of the aircraft manufacturing workshop to formulate a safety standard, and then this standard is the standard for supporting factories to provide aircraft parts in the future, and then extend to the aviation department.

In order to escort our own aircraft in the future, it is also to set up some fences to prevent foreign aircraft from setting up some fences .......

Large aircraft manufacturing has attracted the attention of all parties, after all, this is a large aircraft made in China, although it is a piston engine, but don't forget, this is only ten years behind the world, after all, the DC7 aircraft is only ten years.

As for large jet aircraft, I don't dare to think about this for the time being, after all, the technical difficulty is not a level.

The large aircraft manufacturing has not yet come out, and the cement tankers, pump trucks, and mixing plants of the motorcycle factory have passed the acceptance of the superior departments, and the acceptance standard is the manufacturing standard of the motorcycle factory.

The demand for special vehicles in our country is still very large, and the motorcycle factory has established three workshops, one for the production of various equipment for the mixing plant, and the other two are cement tankers and pump trucks.

In addition, you can also build a ground pump, which is already being done, and Liu Hai is still a project team leader.

This set of equipment, the railway department at a glance, with this thing, is it much faster to build bridges or something.

The most important thing is that the materials can be managed in a unified manner, and the quality of concrete can be controlled in a unified manner, which is not too good for the project.

However, this achievement in the face of the upcoming large aircraft, did not bring up any waves, the motorcycle factory just silently added three workshops, and then the relevant departments hurriedly formulated relevant standards according to the test data of the motorcycle factory.

In mid-May '68, the test results of the large aircraft were completed, and the final skin coverage began, mainly in the belly of the aircraft, and the reason for the final coverage was because it was convenient for maintenance and inspection changes during the test.

After the skin is covered, the large aircraft begins to roll off the assembly line, the prototype is yellow, this is used to protect the aircraft skin in flight, and the surface can be sanded and painted after the test.

If it's an aluminum alloy, then it is possible that sanding before painting will make the skin thinner.

When the entire plane was slowly dragged out of the manufacturing workshop, Sun Aiguo looked at the huge plane, and everyone was drunk.

Ten meters high, with a wingspan of 40 meters and a length of 35 meters, the four huge propeller engines look so domineering.

There are also photos and videos on the spot, which is the propaganda department of the factory, and expensive film is nothing in the motorcycle factory.

It is said that the most advanced film production technology of Chick has been introduced, and anyway, now there are people on the pole to sell our respective technical equipment, as long as it is not military-sensitive technology.

Aircraft ground test test, bangs to develop the test content, and then the following people to execute, the first is to carry out the start test, good guys, when it starts like a tractor starts, it spews out black smoke, first start an engine, then the second, the third, the fourth.

When the engine was started, everyone was at a safe distance and communicated with the pilot via radio.

Liu Hai began to command on the test tower next to him, and there was a rescue team next to him, mainly because he was afraid of any accidents.

The amount of refueling at one time during the test is related to the content of the test, and some tests do not require a lot of oil.

Then there is the ground taxiing test, which is to start the continuous test on the runway of several kilometers, the bangs are commanded while the pilot is controlled, and the outside observers observe the various parts of the aircraft, simulating the linkage of various aircraft controls, tails, flaps and so on.

This is repeated not only once or twice, but countless times, and the data for each test is recorded.

Don't underestimate these test processes, which are the foundation for the future aircraft industry.

"Xiaohai, how long will it take for this plane to fly?" When Zhu Haiyang heard that the big plane was being tested, he also came to see the excitement.

"A week after a week of ground trials, test flights began." Liu Hai watched his subordinates busy, after all, the ground test is not a tall thing, and the work that should be done for the people below will be done by the people below.

The testing of large aircraft is more complicated than that of twin-engine aircraft, and the relevant systems are checked after each test, etc.

In fact, 99% of the inspections will not have any problems, the data is very stable, but the data needs to be stable.

Once something goes wrong with the data, it's troublesome...... Even if it is ten times, hundreds of times the data is the same, it must be checked and tested.

"How many people can be seated on this airliner in the future?" Zhu Haiyang looked at the huge yellow plane and asked again.

"About a hundred people, it depends." The seating layout changes according to different situations, for example, there are fewer first-class cabins, and there are more non-cabins.

And at this time, the demand for civil aviation tasks is not very large, at least ordinary people have little opportunity to take a plane, only official business, and a certain level is needed.

The largest demand in China is cargo aircraft, and the number of passenger aircraft is limited.

"Enough, enough." Zhu Haiyang nodded, it is enough for more than a hundred people to sit on a single route, and it is estimated that there are not so many people.

In fact, now most of the routes are enough twin-engine transport planes, twenty or thirty people or something.

Zhu Haiyang's ability to bangs is simply indescribable, a little perverted, the key to this one is so young.

Less than thirty years old has this kind of achievement, this kind of ability, more than many big people I have heard, and I have brought myself out.

Several department leaders pay close attention to the large aircraft, when the large aircraft is going to be flight tested, the superior leaders led the team to inspect the motorcycle factory again, the superior leaders looked at our own large aircraft, led a group of leaders around the aircraft is very walked a few laps, and then entered the wide aircraft inside, looking at the wide aircraft cargo warehouse, the relevant technical personnel are introducing to the superior leaders, what is this for, what is that for.

When the tail hatch is closed, there will be a screeching sound to remind this side to close the hatch, mainly because some of the two goods will be clamped silently.

As for anti-pinch measures, this ...... It's difficult, because even when the bangs are crossing, the so-called anti-pinch measures are more difficult to use.

In this way, it is not strange to have bangs in the future with accidents, as long as it is something that people do, there are times when there are accidents.

Liu Hai didn't go to explain it in person, Liu Hai was outside the plane, Zhu Haiyang also came this time, looking at the superior leaders and a group of big leaders, his mouth cracked with laughter.

is talking to the factory director, and the factory director doesn't need to join in the fun, just these big leaders, Sun Aiguo sees them several times a week.

It is more conducive to the development of the factory to let the following technical personnel contact the superior leaders.

From the beginning of entering the aircraft door, the superior leader took a step to look around, looking at the inside of the wide aircraft cargo compartment, you can clearly see the aircraft beams, longitudinal beams, and various control pipelines sprayed with anti-rust paint, and the aircraft ground is also made of metal.

The superior leaders were very emotional, this is our own big plane, thinking of the most difficult time in the past, when I couldn't eat enough, and I was chased everywhere.

Now it is possible to produce such a large aircraft, although it is said to be an imitation, but as long as you can make it yourself, it is a good thing.

Touching the hot metal, this can't be helped, it's almost June, the outside of the plane's skin has not been painted, and the temperature inside the cabin is not much lower.

The interior of the cabin is dozens of meters long, and the cockpit is in front, and the test pilots are very excited to salute the superior leaders.

The superior leaders also came to the cockpit, but the line of sight in the cockpit of the aircraft was not very good, looking at the dazzling array of various instruments and meters, which were all Chinese characters, and the test pilots next to them introduced them one by one.

The superior leader watched for more than an hour, just inside the cabin, Liu Hai came to the tower side, ready to command the first test flight, the superior leader went out of the cabin, took a photo with the big plane, and then asked other leaders to take a group photo, and he came to the tower again.

"Leadership."

"Leadership." The staff on the tower hurried to greet them and applauded one after another.

The superior leader waved his hand, glanced at the bangs more, and then shook hands with the others.

After the group photo of the other side, all the people were emptied to safety, and then they began to prepare for the first test flight.

"Take off." Liu Hai asked the superior leader to give the order, and the superior leader gave the take-off order here.

The four-engine transport plane began to run on the runway, and then soared into the sky under the eyes of everyone.

The superior leader picked up the binoculars and looked at the big plane flying up, and his heart was surging.

For some time before the test flight, the landing gear will not be retracted, and then it will be five minutes, and after five minutes, it will land .......

On May 28, 1968, the first flight of the four-engine transport aircraft made in China was successful, which represented a new level in the field of aircraft manufacturing in China.

This aircraft is a medium and long-range transport aircraft researched and manufactured by China itself, with a maximum cargo capacity of 30 tons and a maximum flight distance of 9,000 kilometers, which provides a stronger guarantee for China's national security and is another monument in China's aviation history.

Superior leaders lead the .......

The next day, Liu Hai got up in the courtyard and heard the impassioned voice of the host in the loudspeaker.

However, people here in Kyoto understand that this is made by that factory, although it is not said on the radio, but the residents of the east side of Kyoto, when they go to other places, they say, "We can see a lot of planes flying every day, and I have seen dozens of times in the sky, do you know which plane flies how low......

Today is Wednesday the 29th, Liu Hai finally returned to the maintenance department, the test flight will take a short time, there is no need to stare at it every day, there is a problem and someone will naturally report it.

Bangs to design the airliner, that is, to decorate the interior of the cargo plane, remove the rear hatch to add sealing and pressurization settings, air conditioning, lighting, seat layout and so on.

In the past few months, Liu Hai has too little time in the maintenance department, so he comes to change his clothes every day, and first comes to the place next door to breed the king eight, only two of the basins are the size of the basin, which has been placed outdoors, and the outdoor has made a pool, and the room is empty.

The number of mice is relatively large, and the mice have successfully grown tumors, and the bangs are ready for a comparative test.

After returning to the office, as soon as he took out the drawings or something, Sun Aiguo came in.

"Everyone is relieved that the large plane has successfully flown this time, and we will look at the test results." Sun Aiguo saw Liu Hai pouring tea for himself, and he didn't stop him, and said.

Bangs nodded: "Yes, I'm also worried about something wrong." ”

Liu Hai must be worried in his heart, design is design, and the real thing is to see the result of flying, after all, whether it is a mule or a horse depends on taking off.

"How's the data now?" Sun Aiguo blew the foam on the tea water and asked.

At this time, making tea is not so particular, at least the bangs are not exquisite, and it is not good to be stared at in this era if you are too particular.

"The fact that I'm here proves that everything is going well, and when I'm not in the maintenance department...... Bangs said with a smile.

"How soon do you expect to be ready for mass production?" Sun Aiguo is anxious about mass production now, and we have a relatively large demand for this thing.

Bangs think that it can be mass-produced more, the service life of this aircraft can reach several decades, and there are many fields of application in the future, besides, there are many underdeveloped countries, and when the time comes, it will be the same as a new aircraft?

"For three months, the test flight must be carried out in strict accordance with the process, which is a smooth situation, and there must be problems in the middle of the process, and the time must be extended." This time, bangs are not allowed to casually skip the test, last time the twin-engine transport plane could, which thing was not big, even if there was a problem, the danger was not very great.

"This transport plane is not good, it is too big, it must be tested step by step, the take-off weight reaches more than 50 tons, and if you don't test it little by little, you are afraid that it will be troublesome if something goes wrong." Bangs explained.

Sun Aiguo expressed his understanding and asked, "Next, you are going to design a passenger plane?" ”

"Well, let's get out of the drawings in two months, I have a few ideas here now, and I don't know which one to choose." Bangs don't know how to choose in the seating layout, whether it is better to have more seats or fewer seats.

Sun Aiguo listened to Liu Hai's detailed explanation, and then said: "Write a rough plan, and I'll submit it." ”

Sun Aiguo also knows that there are not too many seats on the plane at this time, so it is necessary to pay attention to comfort

"Did you say you could fly abroad?" Sun Aiguo is thinking about international routes, and there has been no break between domestic and foreign countries, third world countries participate in various activities, participate in academic conferences, and some calligraphers and artists go to sea for exhibitions.

In addition, I go to the United Nations for meetings and so on, international routes have a lot to do, and my own plane feels more comfortable to use, every time I take someone else's plane, this is a bit .......

"Well, of course you can ......." Liu Hai didn't know what to say, because at this time, he didn't understand what kind of regulations were in the world.

"I'll ask my superiors to see if there's anything to be done by the dealer." Sun Aiguo asked Liu Hai what he thought.

Bangs nodded: "This is okay, but maybe you have to take the plane to test, right?" ”

"I'll ask this first, anyway, it won't delay things, but Her Majesty's yacht, can you put it on the agenda, with this thing, it is estimated that those dealers will be easier to talk to." Sun Aiguo spoke again.

Liu Hai nodded: "I'll start thinking about it first, and then start designing." ”

"Actually, you should find a life that takes care of you, it's still hard to be alone." Sun Aiguo looked at the bangs and felt sorry for the bangs alone.

"Factory director, if I find one, I won't have so much time to work overtime, and I'll tell you when I have an idea in the future, I don't have to worry about eating and drinking now, and I can arrange it casually." Liu Hai hurriedly stopped, what is the matter with this factory director.

Although it is common for superiors to care about the lives of their subordinates at this time, you are such a big factory director, you have nothing to worry about your own affairs.

"Will you go to see the location of the TV tower?" Sun Aiguo asked again.

Liu Hai shook his head: "No, I have a lot of things to do here." ”

Kyoto TV Tower is still in the old position.,Bangs made a rendering.,Copy the Oriental Pearl.,As for the TV station building.,I haven't figured out who to copy yet.。

Anyway, I will produce a rendering by myself, and the rest of the specialized architectural designers will design, and I will not have time to design.

"The houses facing the street here are going to be built into six storeys high, and all of them are set back to be used as office buildings, shopping malls, etc., and I am going to build an exhibition hall to show the development history of our factory and the products produced, just like the prototype aircraft of this test flight, which can be placed in it." Sun Aiguo said here.

"Of course you can, but there's no need for the plane to be indoors, it's too big." Bangs asked.

"Of course, and we must protect it, and wait for a hundred years, two hundred years later, there will still be people who can remember, be able to see the efforts of our people from these things, and also witness the development of society." Sun Aiguo doesn't care about what land is occupied, what is not there in the place?

"There's no need for renderings for this."

"Of course we want it, our own home, but also to do a good job, and when we make a sports car or something in the future, we can put it in, don't make a better place, it looks bad."

"Okay then." Liu Hai knew that he was famous in the design circle, and he also knew that the dealers who designed sports cars and other things in the past were given money, but the money was not given to himself personally, nor to the motorcycle factory, and was handed over.

Of course I don't care about bangs, I won't want this thing for myself, it's millions of pounds bigger before and after, it's ...... I can't afford it, the key is that it's useless, converted into mainland currency, tens of millions...... At this time, there is no place to use a thousand, let alone tens of millions, it is better to give it where it is needed.

If you really take it, which is the target ...... come out?

"The credit for the equipment of the pump truck has changed the wine for you and put it in the back, as for the big plane, I don't know what to reward you anyway, and the higher departments will definitely arrange it when the mass production is completed."

"Leader, these credits are not my ...... alone."

"I know that the people in these project teams of pump trucks and so on have been rewarded, not only have money but also certificates, and they will be given priority ...... house or something."

Two more and 10,000 words completed.
