Chapter 500 Headache (first update)

The helicopter workshop is always the top priority, and Liu Hai is holding the responsibility card made in the workshop yesterday.

Carefully examine the various things done yesterday in the helicopter workshop.

Everyone else was waiting nearby. After Liu Hai checked it, he signed: "Well done. It doesn't matter if you do it a little slower. You must not make any mistakes. You must follow the process."

A precision and expensive thing like a helicopter really requires attention to every detail, even a rivet or a screw.

If you think that one rivet or one screw is not a big problem at the beginning, it will have no impact on the whole.

So once this kind of dangerous thought spreads or stays in the mind for a long time, there will be a second rivet or a second screw.

The production progress of several sample helicopters in the helicopter workshop is very slow, but Liu Hai never rushes them.

Because on the one hand, this is to train technical workers, and on the other hand, it is to lay the foundation for the subsequent mass production process.

Now when laying the foundation, we don’t seek speed, but stability and quality.

I won’t say much about bangs. Anyway, if it doesn’t fit, I’ll have to dismantle and reinstall it.

Of course, the yield rate of parts is now horribly low, with some complex parts being less than 50%.

This is something that can't be helped. After all, these skilled workers have only been exposed to helicopters for a few months.

However, despite making mistakes again and again, the growth rate of these skilled workers is still very good.

"Thank you Liu Gong for the compliment." Li Dali and others also breathed a sigh of relief. It is a great honor to be praised by Liu Hai.

"You guys go ahead." Liu Hai signed the responsibility card and handed it to Li Dali, and then went to do his own thing.

This is how Liu Hai spends his time every day. In the morning, he basically walks around each workshop and the time passes.

In the afternoon, Liu Hai made drawings. After the drawings came out, they were sent to the equipment department.

Liu Hai gave the drawings to the equipment department and the manufactured parts had to undergo secondary finishing on his own side before continuing with heat treatment.

This will greatly reduce your future labor intensity and save time.

In fact, the processing speed of CNC machine tools at this time is not comparable to that of a skilled senior technical worker.

Especially in the conversion of fixtures and other aspects, the current processing speed of CNC machine tools cannot match that of senior skilled workers.

But it has an obvious benefit, allowing ordinary skilled workers to use CNC machine tools to produce finishing parts that only advanced skilled workers can produce.

If it is just a CNC machine tool, it certainly doesn't make much sense. It cannot be as fast as a machine with a level 6 or 7 skilled worker.

But there are one hundred or two hundred CNC machine tools, and the operators only need simple training to process parts with high precision.

This is the meaning of the existence of CNC machine tools. Of course, each component has its own processing program.

This is also the reason why some people are not optimistic about CNC machine tools in the early days.

Because comparing just one machine is not of much value. Even at that time, some master craftsmen still exceeded CNC machine tools in terms of processing speed.

The development of CNC machine tools abroad is related to the social system at home and abroad.

From the perspective of foreign capitalists, if a low-level skilled worker can make parts that can only be processed by a high-level skilled worker, the labor wages alone will be much lower.

In other words, the cost will be reduced a lot, so of course capitalists will vigorously develop CNC machine tools.

And our current one is still a planned economy, which is actually not sensitive to labor costs and industrial costs.

Of course, the reason why we have not developed in history has a lot to do with the lack of money and the lack of technical sources for reference.

Occasionally, one or two CNC machine tools are produced. When the leader takes a look, that's it? It's not as fast as a high-level skilled worker can produce.

Because our labor costs are almost negligible at this time.

This is not the case abroad. As long as foreign capitalists can reduce costs, they will vigorously develop it.

To put it bluntly, the dynamics of the two are different.

The three-axis CNC machining equipment manufactured by Liu Hai can be said to be the simplest CNC machining equipment among them.

A single one makes no sense, but if a huge motorcycle factory equips one or two hundred units, it will show different effects.

The first snowfall of 1972 came, and overnight, the sky and the earth turned white.

If nothing else, snow clearing will start again. There are already snow clearing machines on the streets here in Kyoto.

It is a machine similar to a forklift that collects snow while shoveling it and transports it away with a tractor.

However, everyone still needs to clean the alley together, because large machines cannot enter the alley.

Snow must also be removed from the roofs of each household to prevent the house from being crushed.

Of course bangs are unavoidable, so work hard to clear the snow.

While Liu Hai was clearing snow here in Kyoto, the third prototype helicopter produced by the motorcycle factory started from Kyoto to the plateau airport to conduct the first helicopter test on the plateau.

The current helicopter sample can only be tested during the day, because the various equipment on it is not complete, and there is no possibility of taking off and landing at night.

The third prototype helicopter rolled off the assembly line at the motorcycle factory twenty days ago.

Then depart from Kyoto, fly across the Central Plains, then fly to Chang'an, fly from Chang'an over the Qinling Mountains, and then arrive at the capital of Shu.

Immediately afterwards, maintenance was carried out in Shudu, and the test flight personnel formulated a detailed flight route here.

This is the first helicopter to go to the plateau. The light helicopters produced before have no ability to fly on the plateau.

It’s just that the imitation Gazelle helicopter cannot fly on the plateau because of the design of its own power system.

In addition, it is a single shot, so the importance of this test is self-evident.

Moreover, it is winter now, and the environment on the plateau is even more terrible and terrible.

However, the test pilots are confident in conducting the test flight, because the test pilots have one month of driving experience and do not know everything about the performance of the helicopter, but they have a lot of understanding.

Because this sample helicopter does not have a pre-installed weather radar, it needs to continuously report local conditions from the ground.

A strict flight plan was developed and several contingency plans were developed.

The main thing is to open up different emergency landing locations on the flight route.

Thanks to the continuous road construction of Route 318 over the years, tunnels have been opened with shield machines in many places, coupled with a large number of mechanized operations, the road condition of Route 318 from Shudu to Plateau is now considered good.

There are many military stations along the way. Originally, the straight-line flight distance of the helicopter should be the shortest, but in order to ensure the safety of the test and test pilots, as well as the property safety of the aircraft itself.

The helicopter flew along Route 318, and various units along the way were ready for emergency rescue. In the past, Route 318 was a nightmare for all car owners in winter. It was one thing to have bad road conditions and often encounter various extreme conditions.

In addition, the cars of the past were not that good, so if something broke down on the road, it could easily cause casualties.

However, when cars and four-wheel drive vehicles can be mass-produced in China, the probability of accidents will be very small.

In addition, each military station has its own mechanical equipment, so even if there is an emergency, it is easy to rescue. Of course, the ease mentioned here is relative.

Shudu has received rare sunshine today. From the airport, you can see the snow-capped mountains in the distance, which are so beautiful under the sunshine.

However, the crew in charge of the test flight was no longer in the mood to watch this. Although the aircraft was inspected every day, inspection before takeoff was necessary.

After the inspection was completed, the test flight crew members received the order for the test flight.

"If this big guy successfully completes the plateau test flight, it will be easy for us in the future."

"Yes, if anything happens on the road in the future, a helicopter can be dispatched for emergency rescue."

"Although fixed-wing aircraft are good, they are greatly reduced in terms of rescue. Fixed-wing aircraft need a runway." Several middle-aged men in military uniforms who watched the helicopter start from a distance said.

"This motorcycle factory is so awesome, it actually installed such a big satellite."

"Not to mention the technical strength of their factory, their factory not only has excellent technology, but also has excellent management. The quality of the same cars produced by their factory is better than other factories."

"If you ask me, I still haven't gone to court. If not, I might just shoot him. If there is a problem with military equipment on the road, what a disaster it will be."

"Just be content. When we bought foreigners' cars to go to the plateau, we had to leave a letter home every time we set off."

"That's right, it's much better than the imported ones before."

"The main reason is that the previously imported cars on the plateau could not carry as much weight as marked, and no one specially produced cars for us on the plateau."

The helicopter produced by the motorcycle factory is much larger than the several small helicopters on the tarmac. The helicopter produced by the motorcycle factory has been here for several days, and several leaders have already had a preliminary understanding of the performance of this helicopter.

The ease of crossing the Qinling Mountains has proven his reliability.

The overall color of the helicopter is yellow, which is helpful for ground personnel to observe the helicopter.

Several leaders returned to the tower, and then there was a long wait.

The 318 line from Shudu to the plateau is about kilometers. Of course, helicopter flight will save a lot of time. They only need to fly through the sky and do not need to climb mountains and ridges to calculate the mileage.

Several leaders waited silently inside the tower, and finally good news came from the first location.

The ground personnel there reported that the helicopter passed through the area smoothly, and the leaders breathed a sigh of relief.

At the same time, the helicopter was also reporting on the situation, constantly climbing over mountains one after another.

The crew members were no longer nervous. They could only fly according to the radio positioning route.

The radio positioning system here actually used to serve fixed-wing aircraft.

That is to say, radio transmitting stations were established on the plateau, in the middle, and in the capital of Shu.

The aircraft determines its altitude and position based on two or three radio transmitting stations.

The helicopter set off at eight o'clock in the morning, and good news kept coming out along the way, climbing over mountains one after another.

On these flight routes, ground personnel are also constantly reporting that the helicopter passed their observation points safely.

The helicopter flew to its destination on the plateau before noon.

There are also many leaders in green military uniforms here at the Plateau Airport. They almost jumped with joy when they saw the large helicopters we designed and manufactured landing at the airport.

Although fixed-wing aircraft are not problematic when used on plateaus, they have great limitations.

It is obviously much better to use helicopters on plateaus, especially at various outposts or other places.

"Welcome!" Several leaders watched the crew members get off the plane and quickly came over to shake hands with the crew members while looking carefully at the yellow helicopter.

These leaders have long known about the existence of this type of helicopter, and they are eagerly looking forward to the helicopter being able to soar on this plateau.

Transportation on the plateau is underdeveloped and many places are no-man's land. Sometimes something goes wrong and ground rescue is very difficult, especially in winter.

"This plane can carry four tons?" Several leaders asked about the specific situation while shaking hands with the crew members.

"When tested in Kyoto, it could lift four tons."

"Can a machine gun be mounted on this?"

"You can also install a cannon down here."

"Can it hold a dozen people?"

"Yes."

The helicopter produced by the motorcycle factory set off from Kyoto and successfully crossed the Qinling Mountains, then landed in Shudu, and successfully reached the plateau from Shudu.

The news reached Kyoto at noon.

"Okay, that's great." The superior leader looked at the report below and said, "Okay."

"The Zero-3 helicopter will conduct a series of tests on the plateau. According to the crew members, there should be no problems. The helicopter is still very powerful." The leader of the department responsible for the helicopter reported below.

"With this helicopter, we can be more convenient on the plateau."

"When we open up all the tunnels above Line 318, the plateau will become a smooth road."

"Comrade Xiao Liu has written a management method for rare minerals. Several of our leaders discussed it and felt that this management method is very good." The department leader said again.

No one said a word against the management methods Liu Hai came up with. How many department leaders benefited from these things Liu Hai came up with.

In fact, our country is a society of favors. If you help me, I will help you.

No one will say that Liu Hai's management method is not good. If anyone says that this management method is not good, believe it or not, others will stand up and criticize.

How much contribution has Comrade Liu Hai made? Can Comrade Liu Hai's vision be matched by ordinary people?

"Then follow the method he wrote. We don't need to export rare minerals now." Of course, the superior leaders know that if we dig more of these rare minerals, we will get less, but there was no way before, and there was nothing that could be exchanged for money.

"Okay, but Comrade Xiao Liu has made great achievements again this time, and his share of overseas profits this year has reached more than 400 million US dollars." The department leader reported again casually.

When the superior leader heard this, he rubbed his forehead and said: "Comrade Xiao Liu is good at everything, but his achievements are too fast and his achievements are too great. Let's ask him what he thinks."
