Take Off My Aviation Era

Micro-precision, not only small but also precise, it is equivalent to a dojo in a snail shell, and a large amount of things can be accommodated in a square inch.

The manufacture of chip circuits is a typical micro-precision process, and it is also nano-level super micro-precision that is difficult to see with the naked eye.

In the field of aerospace manufacturing, although it has not reached the nano-level metamorphosis of the chip, there are also many parts that have reached the level of micro-precision, such as the film cooling holes of the turbine blades, and the front and back of the palm-sized blades. After that, nearly a hundred small holes will be made.

Although the size of these small holes is visible to the naked eye, the precise, stable, and one-time molding of these holes requires extremely precise micro-manipulation, so this type of process holes are also classified as micro-precision.

At this moment, the flame tube in the hands of the middle-aged aviation expert from Algeria is full of such small process holes like the film cooling holes of turbine blades, like tiny honeycombs, and like a marching array, dense and organized. Are distributed around the flame tube, giving a unique industrial beauty.

But the middle-aged expert holding the flame tube did not want to appreciate this unique beauty, but stared at these small holes. There is no way that these holes are made too fine, although there is no metallographic analyzer and electron microscope, but Middle-aged experts rely on years of experience to judge that the equipment for making these holes is definitely not simple.

"I don't know the effect of the hole array using this micro-precision process?"

Just when the middle-aged experts and others around were inspecting the craft holes on the flame tube, and exclaiming loudly and marveling at the distribution and beauty of these holes, Aziz, who had never spoken, suddenly mentioned it to Tengfei Group. The key question.

Hearing that, Abdullah and Mahmoud looked at Zhuang Jianye at the same time, but Zhuang Jianye smiled slightly, and directed at a few laboratory technicians in white coats not far away: "Make the same model of the test bench The combustion chamber is opened, allowing experts from both countries to guide and guide."

Several technicians responded, and immediately walked to the console, and after a little preparation, they turned on the switch, and with a beep, one of them was in the hands of the middle-aged expert on the experimental platform not far from everyone. The interior of the same product with the same combustion chamber was immediately shrouded in flames.

At the same time, the two rear-projection color TVs on the side immediately displayed relevant pictures, one is the infrared imaging picture in the combustion chamber flame tube and the internal gas flow dynamic picture generated by the computer according to the combustion situation and airflow distribution; the other It is the external monitoring of the test bench and the temperature changes in the center of the combustion chamber, the inner wall of the flame tube and the outside.

At first, Aziz and others didn't feel much about it, but when the center temperature of the combustion chamber reached 1832 degrees Celsius, Aziz's old face became unstable.

It should be known that this core temperature has reached the maximum temperature of the flame tube of the M88 small bypass ratio turbofan engine used by the French Rafale fighter.

And this temperature has only been reached once in the European Aerospace Agency’s laboratory, because this kind of extreme temperature test is enough. After all, the combustion chamber is not a casual firewood. It is known that the M88 combustion chamber can have an extreme temperature of 1832 degrees Celsius. Value will do.

After all, in actual use, the temperature of the flame tube of the M88 can only be maintained at 1587 degrees Celsius at most, no matter how high it is, there will be problems.

But now, the center temperature of the combustion chamber of Ascendas Group can not help but reach the extreme value of the combustion chamber of the French M88 engine at 1832 degrees Celsius, and it is even more pressureless by one degree Celsius, and a steady rise of one degree Celsius.

This has made people uncomfortable. As a result, after looking at the computer-generated gas flow dynamic graph on another screen, Aziz was even more surprised.

Most of the red heat flow in the middle is wrapped in a layer of shallow light blue air current, spinning like a tornado in the flame tube. The so-called wind borrows the power of the fire, and the fire borrows the wind. This is the case for the outside forest fires. The same is true for combustion heat flow.

In addition to the oxygen brought by the compressed air of the compressor, combustion-supporting oxygen is also provided in the cooling air model. Coupled with the internal rotation, not only the fuel and oxygen are fully mixed and burnt, but the combustion is completely isolated from the inner wall of the flame tube. , So that the temperature of the flame tube always stays at a constant value.

From the result that the detection temperature of the inner wall is 1189 degrees Celsius, the outside is only 800 degrees Celsius, and the two sets of numbers are very constant at 3 degrees Celsius, the efficiency of the internal rotating gas film of the flame tube is quite high.

Yes, it is really quite high, because the core temperature of the combustion chamber has reached 2057 degrees Celsius at the moment.

"This...this...this..."

At this time, Aziz was completely shocked. It hasn't happened for a long time. It's no wonder that the UAE prince who has been in the European aviation technology industry for most of his life will be like this. This value is really amazing. In his entire life, he had only listened to his American colleagues at a certain academic exchange meeting, but he had never seen a combustion chamber that could withstand high temperatures above 2000 degrees Celsius.

Because of this, when Aziz witnessed the miracle with his own eyes, the whole person was as if living in a dream, and his consciousness was completely tranced, only feeling that all of this was not real.

Where is this place? Is it China? Has the Chinese taken down the key components of the next-generation fighter jet?

You know that the Europeans are still rubbing in this field; the Russians are still pooling money in this area; the Chinese have already achieved results?

"Gentlemen~www.readwn.com~This is the WC-6 "Honeycomb Combustion Chamber" developed by Ascendas Group for the third generation core machine of HX-25-17. The internal flame tube adopts the original creation of Ascendas Group. The gas film cooling hole array, as shown on the screen, the entire combustion process is violent and stable, and the key rotating gas film can completely protect the inner wall of the flame tube from high temperature erosion.

This technology currently has two companies in the world with independent R&D and production capabilities. One is Pratt & Whitney in the United States. They used this in the combustion chamber of the F-119 high-thrust turbofan engine produced for F-22. This technology; the other is our Ascendas Group, and we will also be equipped with this technology on the WD-80S high-thrust turbofan engine that we are equipped with for the next-generation combat aircraft Zhenlong MAX..."

At the moment when Aziz was in a trance, Zhuang Jianye's unhurried voice came faintly, so that Aziz finally recovered, and Zhuang Jianye framed the topic on the True Dragon MAX next-generation fighter plane and WD-80S. The engine did not say anything about the sale of equipment or the transfer of the production line. After all, Zarif’s news was secretly given. Zhuang Jianye could not dispel the careful thinking of Abdullah and Mahmoud, so he could only fight for the next generation. The aircraft cooperation is unfolding, and what is the core of the next-generation combat aircraft?

Of course it’s an aero engine, so Zhuang Jianye is unambiguous. He brought out the key technical achievements of the next-generation engine and directly compared the standard F-22 F-119 engine. If this is not a king bomb, what is it? !
