Chapter 310: Many tasks (first update)
Everyone in the maintenance department is very curious. Wood can actually make airplanes. This is beyond everyone's imagination. The main reason is that everyone thinks of airplanes too high.

Now, unlike the people in the back, who can accept any kind of knowledge with the Internet, the people in the maintenance department do not have high cultural knowledge and have basically not received any systematic education.

We only know a few things from meetings and the radio, but many homes don’t even have radios.

Not to mention TV and other stuff.

Therefore, when the aircraft parts were sent to the maintenance department, the employees in the maintenance department were shocked, but they believed Liu Hai.

But believe it or not, I must still be very curious. When assembling the aircraft, everyone was very active.

The first is the entire frame of the aircraft, and then the equipment, engines, and related control systems are installed on it. Liu Hai uses a transmission rod type, which is also the most common operation method before wire-wire and hydraulic control.

It is most cost-effective to use a transmission rod type for this kind of small aircraft. There are usually two sets of hydraulic systems. If one set fails, the other set will be used. When I first watched the movie, the fighter in the aircraft used all his strength to pull the rudder.

It is this type of transmission rod. Even in the earliest days, steel wire transmission was used. However, steel wire has some shortcomings due to its ductility and other characteristics.

This small aircraft can be controlled with brute force and has no problem at all.

The aircraft is mainly controlled by controlling the elevator, aileron, and auxiliary rudder.

After the engine is installed, the transmission equipment and some instrument panels are installed. There is also a radio station inside that can communicate with the ground, as well as supporting batteries and generators.

There are also installed lights. After installing the internal equipment, it is time to install the wings and fuselage.

These are all made of wooden materials, which are actually better plywood. After the corresponding shapes are created, the surface is treated accordingly, and some metal skeletons are filled inside.

After the fuselage is installed, the control system must be tested.

Liu Hai was debugging while controlling it, mainly debugging the transmission rod.

"How's it going?" Sun Aiguo was delayed by something today, so he hurried over at this time and asked anxiously before anyone arrived.

"Director, we are still in the debugging stage." Liu Hai answered while debugging.

It's not that Liu Hai's debugging progress is slow, but that Liu Hai has to explain to the maintenance department how to adjust, which part of the aircraft should be controlled through this, and how to debug.

Employees in the maintenance department do not need to understand the principles of flight, nor do they need to understand various mechanics, aerodynamics, etc. of the aircraft. They are only required to know how to debug and where the parts should be.

Liu Hai has always been like this. Even if the engine is manufactured at the front, Liu Hai will not tell these employees anything about thermal efficiency, high-pressure nozzles, why they are like this, and the mixing ratio of air to fuel, etc., no Needs to be said.

Because this involves such a wide range of knowledge, don’t underestimate this small aircraft. The level of knowledge that can really independently manufacture such a small aircraft is already impressive.

There are many subjects involved.

"That's good!" Sun Aiguo came here. The people in the maintenance department saw the factory director sweating profusely and poured him a glass of water.

Now this plane looks a little strange, very crude and simple.

The first is the front nose position. The outer shell is not installed, and most of the covering parts of the fuselage are not installed either.

Because the transmission system needs to be debugged, the cover cannot be installed.

It looks like an iron frame with a machine on top and then the wings are placed on top.

Although he had seen the renderings, Sun Aiguo still felt a little chilled when he saw the crude appearance of the scene.

This doesn't look as sci-fi as a sports car.

The bangs actually want to copy the kind where the wings are under the belly of the aircraft, and then there is a bubble cockpit above.

But conditions don’t allow it. No one can produce the bubble cockpit now.

Not to mention the small aircraft that use a large number of intelligent systems, chip controls, etc.

Sun Aiguo watched from the side. This kind of small aircraft is very simple to debug and easy to fly.

After debugging, it is time to install the upper cover. After the cover of the fuselage is screwed on, it looks much better. At least there is no exposed metal frame.

After a final check of the engine, it was started.

The bangs are powered by electricity, so there is no need to break the paddle in front.

The engine started smoothly, and after Liu Hai tested it again, he debugged it again.

Then all the covering parts of the aircraft engine are installed. This is of course made of aluminum alloy.

The entire aircraft is orange-red, which is the symbol of a disaster relief aircraft and is also more conspicuous.

"Director? Do you want to find an airport to try?" In theory, the plane can take off right inside the factory, but this is Kyoto.

Who bears the consequences of flying randomly?

"I'll find someone to report here. You can load the car first, and remember to cover the plane with canvas." When Sun Aiguo heard this, he definitely wanted to see the plane fly.

The aircraft was mounted directly onto a flatbed trailer and covered with canvas.

Sun Aiguo acted quickly and reported to the department. The deputy director in charge of military products also reported to the army, and also reported to the Third Machinery Department.

Within 20 minutes, the superiors asked Sun Aiguo to tow the plane to Shahe Airport, and then relevant personnel met there.

Several vehicles, several vans, and a flatbed trailer drove out from the motorcycle factory.

In Liu Hai's car were the deputy director of the military industry and Sun Aiguo, the secretary. Liu Hai was driving.

It was dozens of kilometers away and took more than an hour to arrive. After arriving at the airport, the leaders of the First Aircraft Department, the Third Aircraft Department, and the army all came.

Piston aircraft are not unusual, our Yunwu has been successful for a long time.

But this is an aircraft produced by a motorcycle factory. In the 80s, during our honeymoon period with the United States, they helped us upgrade the aircraft.

They dismantled the parts from our two aircraft and threw them together. As a result, when they were installing them later, they found that parts of the same type and model could not be installed. It was later discovered that the screws of the two aircrafts were used separately.

Of course, it cannot be ruled out that he was hiding his clumsiness in the first place.

The biggest advantage of a motorcycle factory is standardization and generalization.

Nowadays, anything that can fly is a good thing, and as long as the price/performance ratio is high enough, there is absolutely no possibility of rejection.

Looking at the simple small plane being pushed off the flatbed transport truck, the entire plane is small, less than two meters high, and looks a bit mini.

The empty weight is less than 350 kilograms and the take-off weight is no more than 580 kilograms.

The shortcomings are also obvious. The load capacity is very low, and the entire plane can only seat two people.

The take-off distance is less than 250 meters, and the landing distance is even shorter.It uses a fixed landing gear, but the wings of this aircraft are at the top, so the line of sight is particularly good, especially for observing ground targets.

Liu Hai is in charge of flying the plane, and there is a correspondent here at the airport who is in charge of the radio station.

People at the airport control tower were also surprised to see so many leaders.

When a small plane got off the flatbed trailer, many people came to watch the fun.

"What plane is this?"

"Is this too small?"

"I feel like one person can carry this plane."

"With so many leaders coming, it must be something good."

The leaders in the ministry originally planned to let pilots operate it, but Liu Hai said it was just a low-altitude flight and the speed was very low.

The leader had no choice but to let Liu Hai conduct a test flight. This small aircraft has a high safety factor.

The main reason is that the leaders don’t have time. If we delay here, another person would have to explain it again.

Liu Hai received instructions from the co-pilot to take off. The pilot used such instructions as turning and turning.

The plane had already started, and Liu Hai controlled the plane step by step. The plane began to glide slowly, and then increased the throttle.

"The take-off distance is 232 meters." When the plane lifted off the ground, a staff member from the leader's side said, this is the take-off distance.

The plane flew at an altitude of 20 meters for 10 minutes. After everything was fine, Liu Hai landed.

Then he prepared for a second go-around. This time, Liu Hai tested the maximum flight altitude and flew to an altitude of nearly 4600 meters.

After the plane landed this time, the leaders within the ministry did not allow Liu Hai to fly the plane again.

A large group of leaders gathered around the small plane and started asking questions.

"Xiao Liu, is this aircraft expensive to build?"

"It's not as expensive as the 125 motorcycle. These wings and fuselage are all made of wood." Liu Hai knocked on the wings and fuselage.

When the leaders heard this, they also started knocking a few times with their hands.

"Is it really cheaper than the 125 motorcycle?" Some leaders didn't believe their ears.

"That's true in terms of material costs."

"This aircraft can fly at a maximum speed of 210 kilometers per hour and a maximum flight of about 900 kilometers."

"The maximum flight altitude is 4600 meters, with two take-offs, the distance does not exceed 250 meters, and the landing does not exceed 220 meters." Liu Hai introduced carefully.

The key is that the flight cost is very low, and an 80-liter fuel tank can fly 900 kilometers.

Then when we go back, we will definitely not be able to fly the plane back. We will have to put it here for flight tests.

The leaders within the ministry will not say anything until specific data and test results are released.

However, Liu Hai returned to the maintenance department, and Sun Aiguo brought good news.

"They were very satisfied with the sports car we designed for Big Brother last time. We will just give him a prototype within this year." In the maintenance department's office, Sun Aiguo said to Liu Hai.

"I was wasting time earlier to go to the ministry to receive the good news."

"The people in the assault vehicle manufacturing workshop are going to the southwest soon. This time, 2000 workers and their families and children are leaving. They will leave after the children have winter vacation." Sun Aiguo said this, feeling a little uncomfortable in his heart. After all, he is a worker and travels thousands of miles to the southwest.

"It's okay if Big Brother people like us, but Big Brother's attitude towards us is getting worse and worse." Liu Hai was thinking about this year's events in his mind.

This year Liu Hai plans to come up with a decent aircraft piston engine, strive to come up with a slightly larger transport aircraft within two years, and strive to build an aircraft similar to the Constellation transport aircraft within five years.

In terms of automobiles, we are designing a mid-range sedan. The reason why there has been no sedan in the front is because there are now sedans in the mainland, which are Hongqi sedans.

There is also the need to manufacture the shield machine. There are still many things to do this year.

Of course, the most urgent thing is to come up with motorcycle racing, one is off-road racing, and the other is road racing. In July this year, Mr. Huo’s dealer arranged for the Sports Car Association to hold a global motorcycle competition, divided into road racing. racing and cross-country racing.

"Are you ready to continue research on airplanes?" Sun Aiguo was a little regretful today. Although the plane took off, he did not get on it.

Of course, if it goes through the ministry's acceptance and test flight and mass production, it will take more time to fly.

Sun Aiguo still feels a little like he is in a dream. The motorcycle factory can actually manufacture airplanes, even small ones.

It was unthinkable a few years ago. In just a few years, factories can manufacture airplanes. If factories manufacture rockets and the like in the future, Sun Aiguo thinks it is not impossible.

Not to mention manufacturing things like rockets and satellites, Liu Hai is at least better than many big names today.

Liu Hai knows the future development direction of these industries. Just like the TV industry in history, many big-name domestic companies have made mistakes in developing monitors.

At that time, there were liquid crystal displays and plasma displays. Some well-known TV brands placed their bets on plasma displays and spent a huge amount of money to research this.

Just knowing the development direction of Liu Hai can prevent the company from taking any detours in a few decades.

As long as companies do not make detours, they will grow bigger and bigger. Companies that make detours will waste funds and personnel in the wrong direction.

In 2020, Liu Hai knows that many high-tech things in our country cannot be compared with foreign countries.

The first is our traditional radar, laser, and satellite.

Although European and American countries have developed early, by 2020, we will be leading the world in these aspects, including drones.

"We need to continue researching this, but without a wind tunnel, we can only imitate other people's aircraft." Liu Hai nodded and answered affirmatively.

"That's good, how is the design of the motorcycle?" Sun Aiguo nodded. As long as Comrade Xiao Liu continues to study aircraft, he will definitely be able to fly on a large aircraft produced by his own factory in the future.

"The simple design idea for the motorcycle has been prepared, and the renderings have been produced in the past two days."

"You've been working so hard for the Chinese New Year. How about I give you a few more days off to go back to your hometown?"

"It's not necessary during the holidays. I get off work early on Saturday and then come to work on Monday." It's convenient for Liu Hai to have a car now. As long as he is willing to go back to his hometown village after work, he can come to the factory to work the next morning. Anyway, it's okay. No one monitors their commuting time.

However, Liu Hai has been busy digging the basement recently, and the amount of work is still quite large.
