Chapter 1189

After listening to Gu Jingyou's words, Wahid and Suharto didn't say anything, but they were honest and went straight into the new factory.

I can't help it. What Gu Jingyou said is too amazing.

The heavy fighters of the Soviet Union series are very good in all aspects, and can be regarded as the model among the three generations of fighters. However, like all the models produced in the Soviet Union, this type of fighter has obvious shortcomings in service life.

In general, the life span of the body structure is less than half of that of the American F-15 series of the same level, not to mention the latest F-15E, which is even less than one third of that of others.

The explanation given by the former Soviet Union and Russia is that this is based on the summary of their practical experience in war, which is reflected in the military industry, because in their view, large-scale war is a super consumption, and it is useless to make expensive aircraft strong and durable, because no matter how good the aircraft is in the face of large-scale war, it is also a consumable, and the scrapping is very fast, so it is difficult for them It's useless to maintain so much service life. As long as the performance can be maintained, thousands of hours is enough. Moreover, the difficulty of research and development is lower, and the production cost is not too high.

But in fact, it's not the case at all. It's true that the Russians boast low production costs, but they are a bit of a hooligan when they don't talk about the high maintenance costs of high-value equipment.

It is necessary to know that the maintenance cost of combat aircraft, especially the heavy combat aircraft with excellent performance, is usually 3 to 4 times of the purchase cost in the later stage, which is still common. It is not uncommon to pull the crotch a little bit or more than 5 times.

The former Soviet Union and Russia, because of their own life problems, invested a lot in the later maintenance of equipment, which was more than six times as much as the purchase.

In other words, it's true that the former Soviet Union and Russia's aviation equipment procurement cost is low, but in the future maintenance, one by one the low-cost procurement will be replaced intact, not to mention, even higher than the total life cycle cost of some western high price aviation equipment.

The former Soviet Union and Russia are not clear about their own aviation equipment?

Of course, we know better than anyone else. Not only that, the former Soviet Union and Russia know that the probability of large-scale war in the world is very low, so the old theory of the former Soviet Union and Russia is out of date.

With the development of technology, the asymmetric operation mode has become the mainstream, which requires the equipment to have higher and higher technical level. However, the production cost and later maintenance of technical equipment are very high, which does not mean that it can be consumed.

Because of this, the former Soviet Union and Russia also want to learn from the west, and make some new equipment with high production cost, longer life and more convenient maintenance, so as to change their increasingly high equipment maintenance expenses.

However, the idea of the former Soviet Union and Russia is good, but in terms of materials, technology and manufacturing equipment, the former Soviet Union and Russia have completely lagged behind the west, and there is no way to further improve the service life of aircraft.

But what if we have to point to these so-called Soviet heritages and sell them for life? Naturally, the old military theories of the former Soviet Union and Russia should be moved out in order to deceive the buying countries. The problem of the service life of our aviation equipment is not a technical problem as the Westerners say, but a problem of concept. In fact, our level is not inferior to that of the West. I don't believe you can buy it back and touch the Western products to see if you can kill them.

Not to mention that the Russian trick has really made some countries dizzy. For example, in New Delhi, as soon as his head was hot, he bought more than 100 SU-30MKI, which was still on the drawing. He did not hesitate to be a mouse of Russian experience.

But there are also many countries that remain basically sober, such as Indonesia.

If not, Indonesia will not try to get Russian origin Su-30 parts from New Delhi Stan airlines, in order to reduce the cost of future maintenance.

To put it bluntly, it is totally helpless.

Just as they chose the su-30mk fighter, if the United States could sell the F-15, Indonesia would not buy the su-30mk, because the F-18 equipped by neighboring Australia has already formed an aviation advantage in the region. If they want to offset it, they can only use heavy fighters.

However, out of their care for Australia, the Americans did not buy the F-15 from Indonesia at all. In desperation, Indonesia could only choose Russia. If the jisu-30mk was no longer a heavy aircraft, it would be no problem to suppress the F-18.

As for the short service life of su-30mk It can only be put in the future.

Anyway, the Russians have been improving their Su series heavy fighters, and they claim that they will launch the most perfect Su series heavy fighters in the near future, so that this model can really reach the top.

If that's the case, it's OK for Indonesia to wait a few more years.

But I didn't expect that Russia's so-called most perfect Soviet heavy fighters didn't wait, but met the key ultra long life parts of China's Tengfei group's Soviet heavy fighters.

This made it impossible for Wahid and Suharto not to go in and have a look. One of the major problems of the Soviet heavy fighters is the service life of a series of structural frames and girders between the 64th and 82nd near the engine, even the skin on the body surface.This section is the main bearing structure of Soviet heavy fighters. If there is any problem in this section, please dismantle it for overhaul, or discard it directly.

In this regard, Russia is also very headache, think of a number of ways can not solve, so that the entire series of combat aircraft life is affected.

Because of this, Wahid and Suharto want to see how Tengfei group can do things that Russian manufacturers can't do.

So they followed Gu Jingyou and several other company members of Tengfei group to an open product exhibition workshop. Immediately Gu Jingyou pointed to one of the large structural parts, which is nearly two meters high and four meters long, with two circular holes in the middle: "here are some of the large structural parts that we copied from the bearing frame of the 75th structure of Su series heavy fighters, I wonder if you can see the difference between this structural part and the original product? "

After hearing this, Wahid and Suharto and others almost didn't scold each other. Their eyes are not microscopes. How can they see the difference.

Fortunately, Gu Jingyou didn't show off. He pointed to the surface of the structural frame and said, "we have laid a layer of silicon carbide ceramic coating on the structural frame, so that the overall thermal expansion and contraction level of the frame can be kept at a minimum constant value, and the overall structural strength can be increased by three times."

"Silicon carbide ceramic coating?" After listening to Gu Jingyou's words, Wahid didn't say anything, but Suharto frowned and questioned: "if I remember correctly, the adhesion of this coating is very low, right? Especially in the metal material, once the fighter plane vibrates, it should be easy to fall off, right

"Mr. Suharto was right, so we applied a new process to the structural frame to ensure the adhesion of the SiC ceramic coating."

"What craft?" Suharto asked

GU Jingyou confidently replied: "electron beam texturing!"
