My Strength Does Not Allow Me to Low-key

When it comes to the engines used by fighter jets and helicopters, there is actually a difference, and the difference is not small.

The fighter jet uses a turbofan engine. The working principle of this engine is turbines of different grades at the front end.

At work, a large amount of air is inhaled, and then a part of the air will be sent to the combustion chamber through the compressor, through the internal duct.

After combustion, it is ejected from the nozzle.

The other part of the air is ejected directly from the outer duct.

The fighter jet also relies on these two jets of airflow to obtain a reaction force, thereby gaining forward power in the air.

The helicopter is another matter entirely.

The helicopter uses a turboshaft engine, and the working principle is probably similar to that of a turbofan engine.

It's just that the helicopter does not need to be as fast as a fighter jet, so the concept and design of the helicopter's engine is different from that of the turbofan engine.

Because of the connotation of the helicopter, the emphasis is on improving the unevenness of the air flow so that the air can be fully burned in the combustion chamber.

In addition, a multi-functional air inlet must be designed to prevent dust and gravel in the air from entering the combustion chamber and directly destroying the combustion chamber.

And at the tail of the turboshaft engine, there is an output shaft, which is also linked to a bearing.

And above this bearing, the propeller is linked.

In this way, the turboshaft engine is working, so that the helicopter obtains a forward flight power, and at the same time, it will drive the propeller to rotate through the output shaft, so that the helicopter can obtain an upward lift.

This is how the turboshaft engine works!

As for turbofan engines, we have gradually caught up, but in turboshaft engines, we are still far behind.

For example, after we first introduced the Black Hawk, we borrowed the engine of the Black Hawk and wanted to copy it.

Unfortunately, the final result was that I was dumbfounded as soon as I opened it, and I didn't understand the principle of this engine at all.

What's even more exaggerated is that in the end we actually wanted to restore and put it back, and we couldn't put it back.

Later, we simply dissected the engine and conducted research, but we only discovered that the distance between the Americans and us is really desperate.

For example, the bearings used in the civilian version of Sombra can have an accuracy of up to 6 threads.

In the severe cold area at high altitude like the Qinghai-Tibet Plateau, it can work continuously for thousands of hours without deformation.

It does not affect the performance of the helicopter at all, but our copycat version, let alone working for thousands of hours.

After working for more than 100 hours, he was sent directly to the factory for overhaul.

The gap in materials alone is enough to make people desperate.

Later, we also worked **** the materials, and finally figured out what alloy the Americans used, and then made this kind of bearing.

But with the materials, this processing is starting to make people difficult again.

As far as the accuracy of these 6 wires is concerned, we can't do anything about it.

You must know that the bearing itself is a titanium alloy mixed with chromium and nickel. This special alloy is very hard.

Using an ordinary five-axis linkage machine tool, your tool is not hard enough, and it can't be machined at all.

Even if you buy a hard enough tool, the benches and fixtures of ordinary machine tools cannot withstand the huge stress brought about by high drilling speeds.

The most popular and even caused accidents involving machine damage and injury due to excessive use of machine tools.

In the end, we had to suspend the research and development in this area, after all, it is really impossible!

But looking at the Zhi20 over there, there are also the next generation of gunship helicopters, which are still waiting to be fed.

In the end, we had no choice but to endure it and started a ‘cooperation’ with the French again.

To be honest, since then, our military has also changed its mindset.

After all, for the helicopter, the technological gap between us and Russia and the United States is too great.

If we bite the bullet and continue to do it, it is very likely that in the next few decades, we will always be behind others.

So let’s just work **** the tank, as for the helicopter horse...

The big deal, let's not use it in large quantities on the battlefield.

After all, when a general helicopter appears on the battlefield, it is basically a situation where one party has already obtained absolute air supremacy.

And with our current strength, even if our current fighter strength is very average, there is no country that dare to say that it can obtain absolute air supremacy in a contest with us.

After all, there are too many long-range strike weapons now, our planes are not good, but we have missiles!

And in recent years, the sudden emergence of drones has provided a new development idea for our army aviation.

With the popularization of network intelligent mobile terminals, with the completion of our Beidou navigation system.

Future wars are destined to be intelligent and unmanned as the leading one.

And drones will be destined to take on more and more extensive roles on the battlefield in the future.

So although we can't make a very good helicopter, we can make more drones!

So in recent years, our military's drone technology has made rapid progress.

It can even be said that the Teddy Bear has been completely thrown away, and it has become one of the few countries in the world that can compete with the United States.

Moreover, our drones have been exported to the Middle East in large quantities, and they have performed very dazzlingly in the various conflicts that have erupted in the Middle East in recent years.

The military also attaches great importance to this new type of weaponry.

But that's because there is no hope of catching up in the helicopter field, and now the emergence of Spark technology. ,

Suddenly the military discovered that they had found a tool that would allow them to quickly get closer to the US and Russian helicopters.

Do you think they are very excited?

After all, you have a helicopter, and you don’t have that.

And the role of helicopters in modern battlefields, especially street fighting, is basically irreplaceable.

This weapon can transport soldiers to a strategic node at the fastest speed in street fighting, and can also be used as a firepower output platform.

Provide the soldiers with maximum firepower support, and basically do not challenge the field.

It is a very good all-weather combat weapon platform, so the military actually favors helicopters very much.

Only in the past, we have been unable to make breakthroughs in the field of helicopter aviation, so we have slowed down the speed of development.

The gap between us in the field of helicopter aviation is not just the inability to make high-precision bearings.

The inner processing of this helicopter is also very special.

Different from the connotation channel of fighter aircraft development, although the connotation channel of fighter aircraft development is also a workpiece of curved surface processing, it does not require much radian.

After the air is drawn in, it must pass quickly and then enter the compressor. After the internal passage and fuel atomization are mixed, it is injected into the combustion chamber and pressurized.

The turboshaft engine of a helicopter is a completely different set of working principles.

Because it is necessary to ensure that the helicopter can fly stably at subsonic speeds, the connotation of the helicopter adopts a convergent shape.

The convergent shape actually makes the inner tract more spacious and curved.

The main purpose is to ensure that the airflow can be accelerated uniformly in the duct, and to ensure that the airflow is at the inlet of the compressor to avoid airflow turbulence, so as to cause airflow isolation and cause problems such as engine surge.

Therefore, the requirements for processing tools are very high. It is necessary to process a very large arc of the endotrache, and the strength and air tightness of the workpiece must be ensured.

The reason why the engines of the United States and Teddy Bear can do it is purely because of the strength of their hard processing.

Years of technology accumulation, and have very advanced processing tools.

In this regard, we are far from it.

It doesn't need to talk about the transmission shaft and the bearing, just talk about the processing of this large arc-shaped inner channel, which will make our project worrisome.

Because we really don’t have qualified processing equipment...

Later, why we "cooperated" with France, because of the many key parts, we can only commission other French people to produce them.

In this way, this engine is actually shared between us and France.

The technical parameters of the engine will definitely face a very large risk of leakage.

And France is a traditional ally of the Americans.

Really, if one day, if we have a conflict with the United States, then if the Americans force the French to speak up.

There is no doubt that the French must stand on the side of the Americans.

And maybe they will get us involved in a certain part of our straight 20 engine.

You must know that the French have a consistent record of not being glorious in this regard.

The reason why Iraq’s Sa Mou was beaten in the first Gulf War was helpless.

It is because the computer he bought from France was opened by the French before the war began.

As a result, the entire Iraqi prevention and control command system was paralyzed by the virus.

Because of this, American talents easily opened up an air corridor over Iraq...

So the military also knows that the French can't believe it, but with the current situation, we really don't have a choice.

But with the emergence of Spark Technology's industrial robots~www.ltnovel.com~ we have a choice.

That's why there is a question from the boss before.

Of course Xiao Feng didn't dare to answer indiscriminately at this time.

It's easy to be regarded as a liar.

So even though he already had the bottom line in his heart, he still chose to answer the boss's question carefully.

Then he pulled out the engineers around him, let the military technicians come up with requirements, and let these engineers try to give answers.

Not to mention, when the engineers listened to the military's request and made simulation graphics on the computer.

All the problems are solved...

The big guys were happy, because a heart disease that bothered them was solved with exceptions in this way, so everyone gradually let go. Everyone was very happy to drink this evening...
