I have opened a new book: Global Apocalypse: My house can be upgraded. Brothers, please help me collect it and give me some recommendations!

However, although the material problem has been solved, we are far from finishing.

Especially things like horizontal shaft engines are more complicated to process than fighter aircraft aircraft.

Because it is based on the turbofan engine, it adds a rotor, that is, the horizontal shaft.

While the engine is required to inject airflow backward to generate thrust, it also needs a rotating bearing that can drive the propeller on the aircraft.

This pays great attention to processing accuracy.

In the past, the difference between the Black Hawk helicopters we imitated was the final finishing process.

It can even be said that this one alone makes us want to die of ecstasy.

Because the processing tolerance does not meet the requirements, the engines made seem similar to others.

But the performance is far inferior. Whether it is lifespan, durability, maximum thrust and lift, it is not a little worse than the original ones.

It has been used by other people for fifty or sixty years, but there is still no problem at all when going to the plateau.

But the black eagle we imitated, let alone the Himalayas, even if we go to Qinghai, will have serious problems of panting.

It is caused by insufficient finishing accuracy.

Although we also had the Z20 helicopter in the past two years, it seems that we have successfully imitated it.

However, due to the problem of finishing, the production capacity is only 20 to 30 per year.

If you want to fight violently, then don’t think about it at all.

If this wants to explode production capacity, the aerospace production capacity of J20 and Y20 will not keep up.

There is no way, who can only use a few five-axis linkage machine tools?

Moreover, these machine tools also have to undertake processing tasks in the Navy and Rocket Force.

In addition, in terms of aerospace, our rockets and space stations also need such machine tools to process.

Therefore, the production capacity of our helicopters and fighter jets has never been increased.

Another thing is our designers. After studying the engine for so many years, they have also had many of their own ideas.

Especially in recent years, we have built the largest wind tunnel and we have many supercomputers.

Our aerospace engineers have designed a lot of their own based on experience and Western theories.

It is not that a brand new engine was designed, but that some parts have been optimized on aircraft engines.

To put it bluntly, changing the shape of these workpieces can affect the aerodynamic performance of the entire engine.

However, it was also simulated on a supercomputer, and the simulation results were considered successful.

But when you want to conduct wind tunnel experiments, it won’t work.

Why? Because the shape of the workpieces you designed is too complicated and cannot be produced using existing machine tools.

At this time, six-axis or nine-axis linkage machine tools are really needed to process them.

But let alone six-axis and nine-axis, we have worked hard to get these five-axis linkage machine tools, like breaking layers of blockades, and then getting them back.

Therefore, many wonderful ideas can only stay in the theoretical stage, and in the end, the actual production and processing cannot be completed.

Although I have said before, most workpieces can be met by using five-axis linkage machine tools.

But at that time, once the civilian level reached the military level, the required specifications were immediately increased by several levels.

Many workpieces are required to be formed in one piece.

To put it bluntly, it is like putting on a piece of iron, and it will be formed at once and not removed from the stage.

As for five-axis machine tools, it is indeed impossible to do some complex surface processing...

However, these problems were solved immediately after the flexible processing machine tools provided by Xinghuo Technology.

The production capacity that has plagued us in the past is no longer a problem now.

In the past, our J20 production capacity was 20 aircraft a year. Foreign media estimated that our production capacity was limited and we couldn't increase it even if we wanted to speed up.

The most important thing is that the production capacity of Aerospace Engine is limited, and they actually guessed it right.

However, our official has never given any response, but some people who are proud of their face have given explanations.

What to say, we don’t fight, so there is no need to produce so much.

Besides, there is so much production, isn’t it expensive to keep it there?

So our strategy is to produce slowly, improve while producing and upgrading...

In fact, those who know how to be aware of this is to gild their faces...

If the quantity is really not important, why do you have to put dumplings on your warship?

Originally, the performance of our fighter jets was not as good as the F22. The quality could not keep up, so why didn’t the quantity keep up?

Especially in such extremely complex surrounding environments now...

Unfortunately, the military does not want to do so, but the production capacity is really not up to the point.

Now that we have a flexible machining machine tool, we have only given it to the Air Force for a week.

In the Air Force, J20 alone has achieved a monthly production capacity of 20 aircraft.

This has been keeping a close eye on the data given by the media in some aspects of our latest fighter jets.

These guys want to know our military strength more than they themselves.

I follow the satellites in the sky every day, counting our planes and warships with my eyes, and I am even more afraid of making mistakes in terms of quantity.

Recently, our fighter jet production capacity has increased sharply, which has made them puzzled.

Issue the solution? Why? Can't figure it out!

We are clearly in the precision processing area, and we are clearly grasping it!

Why did their production capacity increase?

In fact, as long as you can build aircraft engines, you know what is the difficulty of aircraft engines in this fighter aircraft.

The first is the material, but after you overcome the manufacturing of nickel-cobalt-chromium alloy, the manufacturing materials of Aerospace Engine are basically fine.

Then there is the start-up design. To put it bluntly, the layout of the airways and blades in the turbojet engine.

This is one of the three key difficulties in Aero Engine manufacturing, and countless designers have racked their brains for these layouts.

Just to slightly change the shape or layout of the blades on the rotor to improve the performance of the aircraft engine.

Then there is finishing, which can be said to account for 50% of the difficulty of aircraft aircraft production.

Because your previous designs, even if the creativity is fantastic, they must be implemented in the end.

You have to produce your creativity and put it on the engine for actual testing.

Only after the actual test is passed can it be loaded onto the plane for use.

So in the end, this finishing is the key.

As for the technological progress we have over the years, the West can be said to be a tracking understanding.

Moreover, through bribery and other means, they have also mastered a lot of progress in the development of our fighter jets.

I know that we are stuck in the finishing process now.

Because of this, they are so stuck in high-precision machine tools.

In the early years, we had obtained a batch of Siemens' high-precision five-axis linkage machine tools through certain channels.

Unfortunately, when it was transported back to China, it was intercepted and detained in the waters of South Africa.

This is a secret battle, both sides have never been in size to open.

But that incident really made us vomit blood.

The money was spent, and not only did not mention the things were taken back in the end, but it also disrupted the pace of our military industry research and development and processing.

And now the processing part can no longer lock our shackles.

Some relevant parties were even more stunned after seeing the surge in our output J20.

Although they said that this is not a fifth-generation machine, there is a big gap between them and the F22.

But in fact, if you want them to really fight with J20, they may not dare.

Why?

This is because when it comes to combat effectiveness of fighter jets, it can be counted not just by advanced aircraft engines.

The key performance of the fifth-generation aircraft is stealth, and another point is speed.

In this regard, the Eagle Kingdom is indeed doing a good job. Their F22's stealth coating can deceive most of the radars in the world, and their F22 can also cruise at supersonic speed when it starts a critical strike.

But one problem is that once the F22 enters the supersonic cruise stage, its stealth performance will not be maintained.
