Chapter 356 The test is completed (first update)
The distance from Kyoto to Southwest is about 1500 kilometers. However, since this is the first long-distance flight experiment, it must fly over a city with an airport. This will avoid problems along the way and enable emergency landing.

The entire flight lasted about seven hours, with two pilots, one correspondent, and two ground crew members in the cargo hold. Sufficient quilts and earplugs were prepared.

Prevent the temperature inside the cargo compartment from falling. In fact, the temperature inside the cargo compartment of this kind of aircraft is not very low.

As the altitude rises by 1000 meters, the temperature drops by about 5 degrees.

The cruising speed of the aircraft is about 300 kilometers. Generally, there is no need to drive the maximum speed, which can reach about 440 kilometers.

The two pilots felt very excited. It was the first time to fly an aircraft we built ourselves, although the engine was more than 20 years ago.

But it had no impact on the two test pilots. The only transport aircraft our country can manufacture independently is the Y-5, and the rest are all purchased from abroad.

If you buy foreign products, you need to buy foreign parts, so when you are training to fly, your time is limited, and parts must be replaced once they reach the end of their lifespan, which costs money.

Moreover, this aircraft is easier to operate, and the rudder operation is not difficult at all. More importantly, when looking at the Chinese characters on the instrument panel, the two of them felt two words - Dejin.

Behind this word are light-emitting diodes, which made the two pilots and one correspondent feel excited. Although they have been test flying for several days, they feel that the aircraft is becoming more and more comfortable as it flies.

The communicators were in constant contact with the ground tower. In addition, the army's radar also paid close attention to the position of the aircraft.

“I didn’t expect this plane to have a de-icing device!”

"I was also surprised when I saw it for the first time."

"With this de-icing device, we no longer have to worry about encountering ice at high altitudes."

"I've long heard that motorcycle factories are very powerful, but I didn't expect them to be so powerful. Such a simple method of de-icing could be thought of."

The de-icing device mentioned by the two test pilots is actually an inflated rubber strip just above the front end of the wing. Once the wing freezes, de-icing measures are directly initiated. When the strip inflates, it will blow the wing. The ice above breaks.

And when the plane flies at such a high speed, these ice blocks are directly blown away by the wind.

This is the simplest way to remove ice, but as long as the flight altitude is not too high, there will be no ice at all.

As for de-icing on the ground, at this stage we can only use manual labor and take protective measures.

"This kind of aircraft is much more maneuverable than the aircraft we flew before, which is conducive to our pilots flying for a long time."

"This time we plan to have a total voyage of about 20 hours and a total distance of more than 5000 kilometers. I feel there is no problem at all."

“The hydraulic control system is just comfortable.”

The correspondents constantly reported various situations to the ground, and the ground reported to Kyoto layer by layer.

The plane flew through one city after another in the air. The two test pilots were very excited and kept paying attention to the instruments.

But here in Kyoto, the department leaders gathered together, everyone was waiting for the good news. As the plane flew over each city, everyone became more and more happy.

As for why Liu Hai was not asked for the project that failed, that is because even if someone was looking for it, they would be blocked.

Generally speaking, others will not let others see the reason for this kind of failed project, because this kind of project can be allocated 1000 million, and it has been studied for such a long time, and it is unknown how many people are working hard behind it.

Now, if we rashly find an outsider to analyze the reasons, what will these people think?
Moreover, even if someone wants to ask Liu Hai to analyze the reason, find the reason or continue to do it, they will be blocked by people like Sun Aiguo.

Other project teams couldn't do it, but you just came here and did it. What does this mean?
In the system, this kind of situation is absolutely not allowed to happen, because other project teams were established through the efforts of many leaders. Others have failed, but you succeed, isn't this a slap in the face?
From a purely technical point of view, bangs should be used to see why?
But it is impossible to say that it is pure technology. Sometimes technology is just a service.

At this time, some people do not understand technology, but they talk a lot about catching up with Europe and the United States. If we directly imitate other people's aircraft, the success rate is higher, but it is obviously not the technicians who have the final say to change this or that. s things.

Liu Hai will not participate in this kind of large-scale team research. Some people don't understand anything, but they just know that exaggerating in it will interfere with the design.

You open your mouth to catch up with this and catch up with that. How dare you say that you don't listen to others?Immediately put a big hat on you!
"Where is the plane?" The superior leader just finished smoking a cigarette, stood up and took two steps to ask.

"The leader has entered Sichuan."

"Sure enough, it has been several hours. It's time to eat. Let's eat first and wait for the good news while eating." The superior leader then looked at the time and found that it had been six hours.

So several department leaders had dinner with their superiors.

There is nothing more to say about airplanes. Although engines are a technology developed more than 20 years ago, as long as you can build your own airplanes, transport cargo, and transport people in the sky, then it is a good airplane.

The airports along the way did not know what kind of aircraft was flying in the sky, only the airports in the southwest.

The leaders of Southwest Airport were like ants on a hot pot, constantly calling to ask where the plane was.

When I heard that the plane had arrived in Sichuan, I felt relieved. After all, it had been flying for six hours, so there should be no problems.

In the southwest airport, the service staff looked at the airport leaders walking back and forth, as well as the leaders of the troops here and whispered: "Leader, it's time to eat!"

"Don't panic, let's eat together when the plane comes!"

"This is our hero. We must take a closer look. What kind of plane is this?" the leaders in the room all said.

"Yes!" The orderly saluted immediately.

The two test pilots on the plane felt very relaxed. In the past, flying a plane was more tiring than working in the countryside. You would be so tired after flying for an hour that you would collapse.

This flight lasted more than six hours, and the two test pilots were not tired yet.

It was already afternoon at this time, and the sun shone on the skin of the aircraft. It could be clearly seen on the ground, because this first aircraft had not been painted yet, and it was the color of rivets and aluminum alloy.

There is no protective paint or the like. The yellow leather aircraft that everyone sees in modern times is because the aircraft flies very fast, and this yellow paint is used to protect the aircraft. In addition, it can also be seen from this layer of yellow paint. The friction is greatest in the air.

There is no need for such a speed of 300 kilometers at all.

When the person in charge of Southwest Airport heard that the plane had arrived, everyone immediately ran out.

The telescope looked at the direction of the plane from a distance. The plane was so shining in the sunset.

"It seems like this type of aircraft has never been seen before?"

"The superior said it was a completely new design, but it doesn't look big?"

"It's very reliable to be able to fly such a long distance!"

Many leaders looked at the appearance of the plane and commented one after another.

When the plane slowly stopped, the leaders took a closer look at the plane. All the rivets on the plane were brand new.

The two test pilots looked relaxed, and the person in charge of the airport asked in surprise: "It seems you are not very tired?"

"Leader, the aircraft uses advanced hydraulic control technology, so we are very relaxed." The two test pilots, the communications officer, and the two ground crew members immediately saluted and replied.

"Regardless of whether you are tired or not, let's eat first!" The leader here said directly without asking more questions.

"Thank you, leader. Let's check the plane first, then refuel it, and take off to the plateau in an hour." One of the two test pilots said.

"Then it's up to you." The airport leader and several other leaders did not force it. They saw two ground staff moving a ladder out of the warehouse and began to inspect it.

The correspondent took the maintenance card at this time and carefully checked each item.

The airport leader and several other leaders looked at the plane carefully, and the more they looked at it, the more they liked it.

"I didn't even hear in the meeting last month that which department's aircraft was going to be successful?"

"Two months ago I heard that the last project failed!"

"Which factory made this? The design is very strange. The engine is placed on the wing?"

The leaders were puzzled as they watched. The leaders present were all related to the army, either the person in charge of the airport or the leader of the army.

After 20 minutes, the ground crew completed the inspection and then refueled.

After the refueling was completed, it was another 20 minutes, and there was only 20 minutes left for the crew to eat.

Pilots are very particular about what they eat when flying for a long time and cannot eat anything that contains too much water.

But this time it was a straight line from the southwest to the plateau, and the distance was only a few hundred kilometers.

"Which factory made this aircraft?" Some things on the phone were unclear. During the meal, the troop leader asked the pilot.

"Kyoto Heavy Industrial Equipment Factory!" the pilot leading the team replied immediately.

The leaders present felt a little confused when they heard this. Fortunately, one leader slapped the table: "Is it a motorcycle factory?"

"The leader is right. We also received an emergency mission a few days ago. The motorcycle factory had already built the aircraft, so we were allowed to go on a test flight." The pilot leading the team nodded while eating.

"What is the configuration of this aircraft? How come the engine is placed in the middle of the wing?" a troop leader asked in confusion.

"The engine of this aircraft is the P51 Mustang engine, which has been optimized and improved."

"I heard from people at the motorcycle factory that the reason for this design is to facilitate the installation of machine guns in the cabin. Two machine guns or heavy machine guns can be installed in the current hatch and the hatch behind."

"It is said that bomb racks can also be set up for bomb delivery."

"Originally, the motorcycle factory was planning to imitate the C46 transport aircraft. Later, it was discovered that the C46 transport aircraft was a bit outdated and could not install weapons." "So it was changed to this." The pilot leading the team had to answer, because the opponent was of high level and could appear in the air. Nothing here needs to be kept secret.

"C46?" Most of the leaders present know C46, ​​but does this aircraft have anything to do with C46?
Not even the engine?
"The people at the motorcycle factory said they would change it, so it became like this."

"The load capacity is 4.5 tons. In addition, a set of combined fuel tanks can be installed in the cabin, allowing the maximum range to reach 4000 kilometers."

"We are conducting a long-range heavy-load test this time. If it succeeds, the motorcycle factory will mass-produce this aircraft, but their factory is already continuing production." The pilot leading the team actually knows the military leaders here, so he can He is said to be an old leader.

There is no way, the military circle is so big now, everyone knows each other when going back and forth.

"Leader, we are about to set off!" The pilot leading the team saw that the time was almost up and immediately stood up and saluted.

"Okay!" Other leaders also stood up and saluted.

Originally, these leaders wanted to ask for credit from the other party, but they were not in charge and had no choice.

Before taking off, I did a general inspection, that is, opening each inspection port and taking a look.

Then the plane began to take off in the last light of sunset. Taking off at night tested the pilot's experience. The two pilots were experienced and would be well prepared on the plateau.

"Hurry up and call the leader. We need this kind of aircraft here. The ones produced by the motorcycle factory should be given priority to us."

"Yes, it's best for us to deliver supplies to the plateau in winter."

"This aircraft has good low-altitude flight performance and can be airdropped."

"It's also good for training airborne troops!"

"I want to call and go to Kyoto in person to report to the leaders." After the plane took off, these leaders chatted briefly for a few words on the way back, and then left separately.

Everyone at the airport who knows about this keeps it a secret, but the pilots can't keep it secret. There are more pilots now, but there are not enough planes. Even the Y-[-] planes don't have enough, let alone imported planes.

The best ones went to fly fighter jets, but you can't fly the fighter jets at this time because the engine life of the fighter jets at this time is too low. It is said that it only has a little more than 100 hours.

The small planes that have been equipped since last year require pilots to take turns flying. The pilots fly small planes to patrol the border, and they feel happy in their hearts. It is better than watching others fly.

Nowadays, this twin-engine aircraft is so big, it will definitely fly without any disadvantages.

After the plane landed in the southwest and took off successfully, the news was reported to Kyoto.

The leaders applauded. It was not easy to fly to the southwest in one go. It took a detour of nearly 2000 kilometers and covered a distance of nearly 2000 kilometers in one go.

This aircraft can carry 4.5 tons or 40 people. At critical times, 100 such aircraft can quickly gather 4000 people.

So what if there are 200?

300, 500, 500 for each unit.

As long as you can make it yourself, the more the merrier.

The superior leaders enthusiastically discussed with other leaders how much of this aircraft should be produced, and then who should be given priority.

Liu Hai didn't go home tonight. He just had dinner and received good news shortly after. The plane landed in the southwest. Half an hour later, another news came. After the ground crew inspected it, everything on the plane was normal.

After another half an hour, the plane took off from the southwest and headed for the plateau.

Liu Hai knew that there was nothing wrong with the plane. The probability of problems with such a low-speed plane was not very high.

Liu Hai knew he couldn't sleep, so he drew pictures in the office. These were drawings for preparing a passenger plane.

To talk about the image, a passenger plane is like a finely decorated house, and a cargo plane is like a rough house.

The factory leaders did not go back tonight. When the plane landed in the southwest and then took off in the southwest, the leaders in the factory also slapped the table in excitement.

In the past, the leaders of the factory did not know the situation of domestic aircraft research and development, but now they know that the aircraft manufactured by their factory is a single seedling in the field of transport aircraft, and it will soon produce passenger aircraft, which is also a single seedling.

As for saying that the engine is backward and other things, no one dares to say it. If anyone says this, a group of sub-factory leaders will tear him up.

This is designed and manufactured by our factory ourselves. Anyone who looks down on our aircraft is looking down on us, so let’s mess with him!
Of course, it is inevitable that some people will feel uncomfortable. They are also modifying the aircraft, so why have others succeeded in modifying it?I spent 1000 million here, but the change failed!
In less than three hours, the plane successfully landed on the plateau again with a load of 4.5 tons. Although the fuel tank was not full this time, everyone was still very excited.

The Plateau Airport had also received news a long time ago. When the plane successfully landed at the airport, a large group of leaders were also here.

The pilots and ground crew leading the team completed the inspection and then refueled. This time it was about 1200 kilometers to the Yellow River.

An extra 200 kilometers of fuel will be added to the fuel volume for this distance.

This time it took off in just half an hour. The leaders on the plateau also hurriedly called Kyoto in private. We are in need of this kind of aircraft. This kind of low-altitude aircraft is suitable for airdropping supplies to border posts and border camps. .

You must know that it is very difficult to resupply on the plateau, and not all aircraft can fly to the plateau.

It was only in the 70s that the third brother next door asked Big Brother to develop an aircraft that could land at the border airport, which was the An-32.

Of course, other people's data is too good, with a maximum load capacity of 6.7 tons, a cruising speed of 470 kilometers, a maximum speed of 530 kilometers, and a maximum altitude of 9600 meters.

It’s a grade higher than this one with bangs.

Of course, the cost of use and maintenance is much more economical with Liu Hai's design, and it is equipped at least many years earlier than the third brother.

Moreover, this kind of propeller aircraft can take off and land as long as the ground is flat and solid, that is, it can land at a field airport.

It is estimated that it will not be long before the third brother next door will scold the two elder brothers sourly again, why don't they give me a plane?

Look at the poor man next door. The plane is flying over the border again.

The department in charge of aircraft equipment was particularly busy on the phone tonight, first from the southwest, then from the plateau, and then from the Yellow River in the early morning.

They all came to complain, saying they wanted planes and so on. The leaders stayed up all night.

For these leaders, it is perfectly fine to stay up all night. During a war, it is okay to stay up for several days and nights.

The plane took off after 12 o'clock yesterday. It flew to the southwest. It took seven hours. It repaired for an hour and then took off. It arrived at the plateau at close to 11 o'clock. It took off from the plateau at 11:[-] and flew for more than four hours to reach the edge of the Yellow River. , refueled at five o'clock and took off for Kyoto.

The distance from the Yellow River to Kyoto is less than 1200 kilometers. Many people at the motorcycle factory have no idea that a transport aircraft was manufactured in the factory.

"Xiao Liu, hurry up and get ready. The leaders are coming to the factory and the plane will land in 40 minutes." After seven o'clock, Sun Aiguo hurried to the maintenance department and found that Liu Hai had already started to wash up. Just one word and he left quickly.

Sun Aiguo stayed up all night, but he almost jumped when he walked. He was so excited.

This time, the superior leader postponed the morning's work and brought a group of people here to wait for the aircraft's heavy load test to be completed.

This flight lasted 20 hours and covered a distance of more than 5000 kilometers, which was enough to explain all the problems, that is, there was nothing wrong with the aircraft.

As a motorcycle factory that manufactures aircraft, it is definitely worthy of the attention of superior leaders.

After seven o'clock in the morning, when the road was busy, the traffic police immediately blocked the traffic, and several minibuses behind the police car passed through the intersection quickly.

Many people are curious, which leader travels so early?So anxious?
The minibus arrived at the entrance of the motorcycle factory, where all the comrades from the armed forces department of the motorcycle factory were already in place.

Even the people working at the steel rolling mill opposite were surprised to see what kind of leader was coming.

When the superior leaders stepped off the minibus and waved to everyone, everyone cheered excitedly.

Those who were about to enter the steel rolling mill quickly waved. The superior leaders waved around before entering the motorcycle factory surrounded by other leaders.

Then everyone looked at each other and laughed, because it was obvious that no one had slept well, and they all had red circles under their eyes.

Then we got on the bus again, because it was several kilometers from the motorcycle factory gate to the motorcycle factory test track. If we walked there, we really wouldn't be able to catch the plane landing.

"You, old comrade, did a great job." The superior leader looked at the runway that was several kilometers long and 100 meters wide. Instead of blaming Sun Aiguo, he shook hands with Sun Aiguo and praised Sun Aiguo for his good work.

Sun Aiguo smiled so hard that his molars almost came out, and he was so excited that he could not speak.

Then a group of deputy factory directors shook hands with the superior leaders one by one. After the superior leader shook hands with the factory director, deputy director and secretary, he asked: "Is there another person?"

"Leader, I'm here." Liu Hai was behind a group of leaders, because when he was getting on the bus at the gate just now, he was grabbed by the leader of the First Machinery Department, and then he kept following the team.

"Young comrade, are you very good? You gave me, an old uncle, another surprise." The superior leader looked at Liu Hai and said with a smile.

Liu Hai only smiled and scratched his head without saying anything, and it was hard to say anything at this time.

Leaders in several other ministries also liked Liu Hai more and more. The long-range and heavy-load test of the aircraft proved that it was a very successful aircraft.

Although it is not as good as foreign advanced aircraft, one thing is that this is an aircraft that can be manufactured and designed by oneself.

Although there are many shortcomings in the aircraft parameters compared to the previous project, the last one failed after all. No matter how high your goal is, as long as it fails, it will be a failure.

Moreover, there are not many planes that can reach the plateau, and the runway of the motorcycle factory is only four kilometers long. The leaders present knew that the factory was going to do something big.

"Leader, the plane has entered the sky over Kyoto!" Sun Aiguo said immediately after receiving the report, so everyone in the group took out binoculars, and even Liu Hai had one stuffed in his hand.

　The second update will be at [-] o'clock at the latest.
