The development of our domestic helicopters can be roughly divided into three stages.

That is, in the initial stage, we learn from Northern Mao and introduce technology, followed by independent research and development.

The symbol of the initial stage is the Z-5 helicopter, which is a copy of the Bei Mao Mi-4 helicopter.

In February 1958, it began to be copied according to the drawings provided by Beimao, and the first test flight was carried out in December of the same year.

This is the beginning of our aviation industry helicopter, and it is a long beginning.

How long is it?

Since 1958, the Z-5 has become the main force of domestic helicopters and has been in production for twenty years.

Yes, the aircraft model has not been changed for twenty years. During this period, the Z-6 and Z-7 were also developed, but due to many problems such as design, the projects were cancelled.

The most core issues of helicopters are lift and gravity.

The Zhi-7 project was rejected because the overall quality was seriously overweight.

So, do we need helicopters in China nowadays? Do we need domestically produced helicopters?

It can be described in four words: eager to see through.

What is the most powerful function of a helicopter?

It is to fight against the torrent of steel, and the anti-tank missile it carries is a can opener.

Our industrial foundation is too weak, even after so many years of belt-tightening.

The aircraft industry really took off after the 1970s, when new technologies were introduced from abroad.

At this time, there are indeed aircraft projects in preparation, such as the 701 aircraft.

However, since the Bell 47 prototype was captured in 1962, mass production has not been achieved until now.

The Bell 47 is still a light helicopter. The prototype can only carry 2 people. Unless a stretcher is tied to the landing gear to transport the wounded, it can only carry 4 people.

In other words, this thing can only be used for reconnaissance, transportation, agriculture, surveying, etc.

Its uses are very broad, but its application is very narrow. So is it important?

It's very important, I want it very much——

Why?

There is an old man in Hong Kong called Cai Lan. He once said that when you have a girlfriend, you should not look at the beautiful or ugly ones.

What is the most important thing about having a girlfriend?

Regardless of whether you are in love or not, you have to have a girlfriend before you can fall in love, so it’s easy to be ugly.

By chance, the Red Star Factory obtained the KH-4 production line and technology from a Japanese company.

This incident was reported internally by the Ministry of Industry and immediately attracted the attention of aviation-related departments.

At the same time, Bingcheng Aircraft Manufacturing Factory also paid attention to the news.

Starting in 1962, it has been five years now, and their 701 aircraft project is almost ready.

As a result, their imitation project collapsed and their hard work was in vain!

There are two situations for imitation.

One is imitation with drawings, just like the Z-5 imitation Mi-4, just take it and copy it.

Of course, the time is very short. It can be tested in ten months, which means that it already has production capacity.

What about Bell 47G?

This is the second situation. It was seized without drawings and measured manually with a tape measure.

Scrap the data from the product, and then figure out the metal properties and production data of the parts.

After all the data is obtained, the production process will be redesigned according to industrial standards.

This procedure often takes a lot of time, manpower and computing power.

Are you talking about future generations of Mishijie?

Stop making trouble, the computers of later generations will be able to match the computing power of tens of thousands of people today.

This is not an equal comparison at all, not to mention that the design of MSJ is also very long-lasting.

The basis for the establishment of Project 701 at Bingcheng Aircraft Manufacturing Plant is that it is currently confirmed that the production data of the aircraft cannot be obtained through normal channels.

Moreover, there is currently no way to obtain replacement products for other aircraft.

There is no introduction and no project development, so imitating the Bell 47 is a helpless move.

Under such circumstances, in five years, this project went from attracting much attention to almost being forgotten now because it took too long.

Compared with the demand for helicopters five years ago, compared with the demand for helicopters now, the international environment has changed, and the development of industry and the military has also changed.

In fact, Bingcheng Aircraft Manufacturing Factory also knows very well that if this project is not taken down, the 701 Project with such a large investment will become a mess.

Well now, there is news from Jingcheng Industrial that Hongxing Steel Rolling Plant will mass-produce KH-4.

Bingcheng Aircraft Manufacturing Factory no longer has the aviation management department to worry about their research and development progress.

Project 701 was directly declared unfinished——

What does that advertisement say in later generations?

Mom no longer has to worry about my studies because I dropped out of school——

Just say, after spending so much budget and so much manpower, can Bingcheng Aircraft Manufacturing Factory be willing to watch the project in hand go to waste?

This was the first time they had heard of the name Red Star Factory. It was located in the far north, at the aviation port, and had no contact with the Red Star Factory.

Looking at the full name of Red Star Factory again, their leader felt even more numb and painful.

Just say, ah——

A steel rolling mill has to produce helicopters, which are more advanced models than their project.

Those who rolled the steel did not roll the steel well, and now they want to go to heaven. Do you think this is irritating or not?

Thank you for not having a steel mill, otherwise you wouldn't be able to produce tanks!

After the detailed information was passed on, their leader asked for clarification and looked at the information again, and was even more dumbfounded.

Hey - don't say it yet!

It’s not that we don’t want to produce tanks, it’s just that there’s no need because they already produce cars.

What the hell - what the hell - ah!

Do you think this is reasonable?

According to the news, it was the leader of their Red Star Factory who told them to get the helicopter production line.

What if you don’t say it?

A year later, I will report the research and development speed of the 701 project, and then ask for a budget.

A piece of material was directly sent to him from above, telling him that the Red Star Factory had already begun mass production for takeout.

Who will be embarrassed when the time comes?

Whoever can’t give birth will be embarrassed!

Originally, Bingcheng Aircraft Manufacturing Factory's suggestion to the higher-ups was to bring over this production line.

After all, the Red Star Factory is just a steel rolling mill and does not have the professional production capabilities for aircraft.

Furthermore, they are an aircraft manufacturer and the research team for this project.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! The whole country is a game of chess, I don’t care where you come from. All industries must carry out their work under the leadership of the organization, and aircraft are under aviation control.

However, this opinion that was submitted immediately fell into disrepair.

There was no reply, no response, just this information was sent back.

It is information about the Red Star Factory and the specific cooperation situation of this aircraft production line.

After reading this, the leader understood that it was not that the aviation department did not want to help, but that it was too busy to help.

If there is just a steel rolling mill across the street, there is no need to mention it. It would be no problem to bring the steel rolling mill over.

But, the opposite is indeed a steel rolling mill, but it will soon be upgraded to a steel group.

Good guy, you want Red Star Factory, and Red Star Factory still wants you!

When an ant swallows an elephant, who will annex whom?

Looking at the materials, Red Star Factory covers many industrial fields such as metallurgy, steel rolling, textiles, chemicals, automobiles, ships, food, and trade.

The leader of the Bingcheng Aircraft Manufacturing Factory was baldly silent. There was nothing more he could say!

How to say?

It's no longer possible to forcefully specify the contract. The explanation of the contract given by others is clear.

This set of aircraft production equipment is a cooperative project industry between Sanhe Co., Ltd. and Hongxing Factory.
