Chapter 393 Test Flight (Second Update)

Logically speaking, these systems should be provided with test reports by the system provider before assembly, but there is no way, these are all manufactured by the motorcycle factory itself.

Liu Hai plans to ask the aircraft manufacturing workshop of the motorcycle factory to formulate a safety standard after the completion of this large aircraft manufacturing. This standard will then be the standard for the supporting factories to provide aircraft parts in the future, and then extend to the aviation department.

To protect our own aircraft in the future, we also set up some fences to prevent foreign aircraft...

The manufacturing of large aircraft has attracted attention from all parties. After all, this is a large aircraft manufactured in China. Although it has a piston engine, don't forget that it is only ten years behind the international market. After all, the DC7 aircraft is only ten years old.

As for large jet aircraft, I dare not think about this for the time being. After all, the technical difficulty is not at the same level.

Large aircraft manufacturing has not yet come out, but the cement tank trucks, pump trucks, and mixing stations of the motorcycle factory have passed the acceptance inspection of the superior department. The acceptance standards are the manufacturing standards of the motorcycle factory.

There is still a huge demand for special vehicles in our country. The motorcycle factory has established three workshops, one to produce various equipment for mixing stations, and the other two are cement tank trucks and pump trucks.

In addition, ground pumps can be built, which is already under way. Liu Hai is still the leader of the project team.

This set of equipment caught the eye of the railway department at a glance. With this equipment, building bridges and other tasks would be much faster than before.

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

However, this achievement did not bring any excitement in the face of the upcoming large aircraft. The motorcycle factory just silently added three workshops, and then the relevant departments quickly formulated relevant standards based on the test data from the motorcycle factory.

In mid-May of 68, the test results of the large aircraft were completed, and the final skin covering began, mainly on the belly of the aircraft. The reason why the final covering was done was because it was convenient for maintenance, inspection and changes during the test.

After the skin is covered, the large aircraft begins to roll off the production line. The prototype is yellow. This is used to protect the aircraft skin during flight. After testing, the surface can be polished and then painted.

If it is an aluminum alloy, grinding it before painting may make the skin thinner.

When the entire aircraft was slowly dragged out of the manufacturing workshop, Sun Aiguo looked at this huge aircraft and was almost 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 were people taking photos and video recordings at the scene, which belonged to the factory's publicity department. Expensive film was nothing in a motorcycle factory.

It is said that the most advanced film production technology of Xiaoji has been introduced. Anyway, now someone is selling us our own technical equipment, as long as it is not military sensitive technology.

During the ground test of the aircraft, Liu Hai formulated the test content, and then the people below carried out the test. First, the startup test was performed. Good guy, when it started, it was just like starting a tractor, spewing out streams of black smoke, first starting an engine, and then The second, the third, the fourth.

When starting the engine, everyone communicates with the pilot via radio from a safe distance.

Liu Hai started to direct from the test tower next to him, and there was a rescue team nearby, mainly because he was afraid of any accidents.

The amount of oil refueled at one time during the test is related to the content of the test. Some tests do not require a lot of oil.

Then comes the ground taxiing test, which is a continuous test on a runway of several kilometers. Liu Hai directs, the pilot controls, and observers outside observe various parts of the aircraft, simulating various controls of the aircraft, tail, flaps, etc. Linkage situation.

This should be repeated not just once or twice, but countless times, and the data of each test must be recorded.

Don't underestimate these test procedures, they are the foundation for the future aircraft industry.

"Xiao Hai, how long will it take for this plane to fly?" Zhu Haiyang heard that the large plane was undergoing tests and came to watch the fun.

"The ground test will begin in one week." Liu Hai watched his subordinates busy. After all, the ground test is not a high-level thing. Let the people below do the work that should be done by the people below.

The test of a large aircraft is more complicated than that of a twin-engine aircraft, and relevant systems must be checked after each test.

In fact, 99% of the inspections will not cause any problems. The data is extremely stable, but the data must be stable.

Once there is a problem with the data, it will be troublesome... Even if the data is the same ten or a hundred times, checks and experiments must be carried out.

"How many people can this passenger plane carry in the future?" Zhu Haiyang looked at the huge yellow plane and asked again.

"About a hundred people, it depends on the situation." The seat layout changes according to different situations. For example, if there is first class, there will be less, and if there is not, there will be more.

Moreover, the demand for civil aviation tasks at this time is not very high. At least ordinary people have little opportunity to fly, only official business, and a certain level is required.

Cargo aircraft are currently in high demand in China, and the number of passenger aircraft is limited.

"Enough, enough." Zhu Haiyang nodded. It is enough to accommodate more than 100 people on a single route. It is estimated that there are not that many people.

In fact, twin-engine transport aircraft are enough for most routes now, with twenty or thirty people on board.

Zhu Haiyang's ability with bangs is simply indescribable. He is a bit perverted. The key to his success is that he is still so young.

He is less than 30 years old and has such achievements. This kind of ability is better than many great people he has heard of, and it has brought him out.

Several department leaders paid close attention to the large aircraft. When the large aircraft was about to undergo flight tests, the superior leaders led a team to inspect the motorcycle factory again. The superior leaders looked at our own large aircraft and led a group of leaders around the aircraft. After walking around for a few times, we entered the large aircraft interior. Looking at the large aircraft cargo compartment, the relevant technicians were explaining to their superiors what this one was for and what that one was for.

When the tail hatch is closed, a harsh sound will be made to remind the other side to close the hatch. This is mainly because some second-hand goods will be trapped silently.

As for the anti-pinch measures, this... is difficult, because even when the bangs are crossing, the so-called anti-pinch measures are often ineffective.

Just like this, it won't be surprising at all if there are accidents with bangs in the future. As long as people do anything, accidents will happen.

Liu Hai did not go to explain it in person. Liu Hai was just outside the plane. Zhu Haiyang also came this time. Looking at the superiors and the big leaders, his mouth broke with laughter.

He was talking to the factory director, and there was no need for the factory director to join in the fun. Sun Aiguo saw these big leaders several times a week.

It is more conducive to the development of the factory to let the technical staff below have contact with the superior leaders.

The superior leaders started looking around after entering the aircraft door. Looking inside the large aircraft cargo compartment, they could clearly see the aircraft beams, longitudinal beams, various control pipelines, and the aircraft ground sprayed with anti-rust paint. Also made of metal.

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

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

Stroking the hot metal, there was nothing I could do. It was almost June, the outside of the aircraft's skin had not been painted yet, and the temperature inside the cabin could not be much lower.

The interior of the cabin is tens of meters long, with the cockpit in front. The test pilots excitedly saluted their superiors.

The superior leaders also came to the cockpit, but the view from the aircraft cockpit was not very good. Looking at the dazzling array of various instruments and instruments, all of which were written in Chinese characters, the test pilot next to them introduced them one by one.

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

"lead."

"Leader." The staff at the tower rushed to greet him and applauded one after another.

The superior leader waved his hand, glanced at Liu Hai one more time, and then shook hands with others.

After the group photo on the other side was over, everyone was cleared to a safe area, and then preparations for the first test flight began. "Take off." Liu Hai asked his superiors to give the order, and the superiors gave the order to take off right here.

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

The superior leaders picked up their binoculars and looked at the flying big plane, feeling very excited.

During the first period of the test flight, the landing gear will not be retracted, and then it will only last for 5 minutes, and the landing will take place after 5 minutes...

On May 1968, 5, the four-engine transport aircraft manufactured in my country successfully made its first flight, which represented a new level in my country's aircraft manufacturing field.

This aircraft is a medium- and long-range transport aircraft independently researched and manufactured by our country. It has a maximum cargo capacity of 30 tons and a maximum flight distance of 9000 kilometers. It provides a stronger guarantee for our country’s national security and is another monument in the history of our country’s aviation. .

Superior leaders lead...

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

But people here in Kyoto all know that this is made by that factory. Although it was not mentioned in the broadcast, residents in the east side of Kyoto will say when they go to other places, we can see many planes flying every day. I have seen I have seen it dozens of times. Do you know how low the plane flies?

Today is Wednesday the 29th. Liu Hai has finally returned to the maintenance department. The test flight will take a long time. There is no need for him to keep an eye on it every day. If there is any problem, someone will naturally report it.

Liu Hailai designed the passenger aircraft, which meant renovating the interior of the cargo aircraft, removing the rear hatch and adding sealing and pressurization settings, air conditioning, lighting, seat layout, etc.

Liu Hai has spent too little time in the maintenance department in the past few months. He comes here every day to change clothes and other things. First, he goes to the place next door where the giant tortoises are bred. There are only two big ones with basin sizes. They have been placed outside. I made one outside. The pool and the room are empty.

The number of mice has increased, and some mice have successfully grown tumors, so Liu Hai is ready to conduct comparative experiments.

After returning to the office, just as he took out the drawings and other things, Sun Aiguo came in.

"Everyone was relieved that the big plane had a successful test flight. Let's take a look at the test results next." Sun Aiguo saw Liu Hai pouring tea for himself and did not stop him. He said.

Liu Hai nodded: "Yeah, I'm also worried about something going wrong."

Liu Hai must be worried in his heart. The design is a design, and the real result depends on the flying result. After all, whether it is a mule or a horse depends on how it takes off.

"How is the data now?" Sun Aiguo asked while blowing the foam on the tea.

There is not so much particularity in making tea at this time, at least there is nothing particular about bangs. If you are too particular about it, it will be bad for people to stare at you in this era.

"The fact that I am here proves that everything is going well. When I am no longer in the maintenance department..." Liu Hai said with a smile.

"How long do you expect it to be for mass production?" Sun Aiguo is now anxious to mass produce it. We have a relatively large demand for this thing.

Liu Hai actually thinks that more can be mass-produced. The service life of this kind of aircraft can reach decades, and it will be used in many fields. Besides, there are many underdeveloped countries. When the time comes, a new engine will be the same as a new aircraft. Already?

"For three months, the test flight must strictly follow the process. This is a smooth situation. If there is a problem in the middle, the time will be extended." This time Liu Hai is not allowed to conduct leapfrog tests casually. Last time, a twin-engine transport aircraft was allowed, but what the hell? It's not big in the first place, and even if there is a problem, the risk is not very big.

"This transport plane is not good. It is too big. It must be tested step by step. The take-off weight reaches more than fifty tons. If we don't test it bit by bit, we are afraid that something will go wrong and we will be in trouble." Liu Hai explained.

Sun Aiguo expressed his understanding and asked, "Are you going to design a passenger plane next?"

"Well, we'll have the drawings out in two months. I have a few ideas here, but I don't know which one to choose." Liu Hai didn't know how to choose the seating layout. Is it better to have more seats or fewer seats?

After listening to Liu Hai's detailed explanation, Sun Aiguo 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 comfort must be paid attention to.

"Do you think we can fly abroad?" Sun Aiguo is thinking about international routes. There is no interruption between domestic and foreign countries. Third world countries participate in various activities and academic conferences, and some calligraphers and artists go overseas for exhibitions.

In addition, when traveling to the United Nations for meetings, etc., international routes are very promising, and it feels more comfortable to use my own plane. Every time I fly on someone else's plane, it's a bit different...

"Of course you can..." Liu Hai didn't know what to say, because he didn't understand what the international regulations were at this time.

"I'll ask my superiors for instructions and see if the dealer can do anything." Sun Aiguo asked Liu Hai what he thought.

Liu Hai nodded: "This is possible, but maybe we need to use a plane to test it?"

"Let's ask first. It won't delay things anyway. But can you put Her Majesty the Queen's yacht on the agenda? With this thing, I think those dealers will be easier to talk to." Sun Aiguo said again.

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

"Actually, you should find someone to take care of your life. It's still difficult to live alone." Sun Aiguo looked at Liu Hai and felt sorry for Liu Hai alone.

"Director, if I find someone, I won't have so much time to work overtime. I'll let you know when I have an idea in the future. I don't have to worry about food and drink now. I can make arrangements by myself." Liu Hai quickly stopped, what is this factory director like? Something happened.

Although it is very common for superiors to care about the lives of their subordinates at this time, you are a big factory manager after all, so you should worry about your own affairs when you have nothing to do.

"Are you going to see the location selection of the TV tower?" Sun Aiguo asked again.

Liu Hai shook his head: "I won't go, I have too many things to do here."

The Kyoto TV Tower is still at its old location. Liu Hai made a rendering and copied the one from the Oriental Pearl Tower. As for the TV station building, I haven’t decided who to copy this one from.

Anyway, I will produce a rendering myself, and the rest will be designed by a specialized architectural designer. I don’t have time to design it.

"The house facing the street here is going to be built to six stories high and set back to be used as an office building, shopping mall, etc. In addition, I plan to build an exhibition hall first to show the development history of our factory and the products it produces, like The prototype aircraft for this test flight can be placed inside." Sun Aiguo said here.

"Of course you can, but there's no need to put the plane indoors. It takes up too much space." Liu Hai asked.

"Of course, and we must protect it well. In 100 or 200 years, there will still be people who can remember it, and we can see the efforts of us people from these things, and we can also witness the development of society." Sun Aiguo doesn't care about occupying land. , the place is not available?

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

"Of course it is necessary. We need to make it better for our own house so that the sports car we make can be put in it. If we don't make a better place, it will look bad."

"Okay then." Liu Hai knew that he was well-known in the design circle, and he also knew that the dealers paid him money for the sports cars he designed in the past. However, the money was not given to him personally, nor to the motorcycle factory, so he turned it over.

Of course Liu Hai doesn't care. I wouldn't want this thing for myself. It costs millions of pounds. This... I can't afford it. The key is that it's useless. When converted into mainland currency, it's tens of millions... this There is no room for a thousand dollars at a time, let alone tens of millions, so it is better to give it to where it is needed.

If you really take it, who will be the target...

"I'll give you the credit for the equipment on the pump truck and put it in the back. As for the big plane, I don't know what to reward you anyway. The higher-level department will definitely arrange it when it is mass-produced."

"Leader, these achievements are not mine alone..."

"I know that people in project teams such as pump trucks and other projects have received rewards. They not only have money but also certificates. They have priority in allocating houses and so on..."

　Two updates and [-] words completed.
