If Pushlenko's shock to Song Tianming before was a kind of impressive thing to look up to, then the shock to Bai Yi at this moment was equivalent to detonating a super-large bombshell in his mind, directly twisting Pushlenko's entire brain into a pile of paste.

Song Tianming is also a regimental-level military commander of the antiaircraft artillery unit anyway, subordinate to the air force, and is considered a high-tech unit; although he does not have much time to contact aircraft, he is not without opportunities; with a little training, and with the foundation of science and engineering laid in the antiaircraft artillery unit, he may not be unable to master the theoretical knowledge related to the ground maintenance of fighters.

But Bai Yi, who is only in his early twenties, is at best the qualifications of a chief guard, no matter from that point of view, he should be a rookie who doesn't understand half hair, which Cheng wants to be such a rookie, but what he says can throw an old bird like him out of 108,000 miles.

Because Pushlenko clearly remembers that when he was training in Moscow for the maintenance of the MiG-15, the instructor once said:

"Jet engines are still a novelty, and there are many things that even the aeronautical designers of the major design bureaus have not fully figured out, so when it comes to the troubleshooting of jet engines, my suggestions are nothing more than two:

First, return to the factory for maintenance; Second, it is still back to the factory for maintenance! Your job is to check the maintenance manual, and you don't need to know that much else! ”

Because of this, even if Pushlenko wanted to understand the technical principles of jet engines, the core idea of Soviet aircraft maintenance was to be simple and fast, and not to engage in such complicated training at all, because, as the instructor said, it was not the duty of the front-line pilots, but the business of the rear repair shop.

Therefore, although Pushlenko felt that the three MiG-15s with fluttering tails were most likely caused by aircraft engines, he knew a lot about piston engines, but he knew very little about the new jet engines, and in addition, he was in the front line of North Korea, and lacked more professional testing equipment.

Therefore, even if there were doubts in my heart, I could not produce corresponding evidence to prove it, and in the end, I could only temporarily seal the three MiG-15s and prepare to return them to the factory for processing.

But what he never expected was that the young Chinese man in front of him was even more powerful than their training instructors, and he could clearly list the adverse effects of the MiG-15 engine in one mouth; if it weren't for Pushlenko's self-taught theory of jet engines day and night in recent years, he probably wouldn't have been able to understand it.

But Rao is like this, Pushlenko still has a strange thing every year, and today there is a lot of déjà vu, Song Tianming suddenly changed from a gossip man to a technical cow, even if it, a young Chinese soldier in his early twenties can understand so deeply in a field that these meritorious pilots regard as a forbidden area, it is simply incredible.

Truth be told, if you don't see it with your own eyes, Pushlenko guarantees that you will feel like you are living in a fantasy!

However, I have to say that even if Pushlenko is a little arrogant and arrogant, and even a little impulsive, he still respects people who are stronger than his own technical ability, and this is true for Song Tianming and Bai Yi at this moment.

So before Bai Yi's words fell, Pushlenko put away his previous contempt and became extremely deferential, and when Bai Yi finished speaking, he stepped forward with a sincere face to ask for advice: "This little comrade, can you speak more carefully, what you just said is really ...... Some general...... Can you elaborate on that? ”

"Yes, yes, little comrade, you still have to talk about it in detail, this is for us...... Forehead...... It's great for both you and me! ”

Lukotsev on the side also stepped forward at this time, smiling like a teddy bear with a spring hair, he could see that the thin young man in front of him was even more powerful than that Song Tianming, and what was more valuable was that what he mastered was exactly what the 12th Fighter Aviation Strike Group needed most.

Just imagine, if the 12th Fighter Aviation Strike Group takes out the main structure failure caused by the jet engine, this kind of theoretical achievement comparable to the development of a new aircraft by the design bureau will come up with such profound theoretical achievements, and the superior's comment that he will be able to study the main battle equipment technology and dig deep into the combat effectiveness of the equipment in his hands will not be able to run, and then several high-value military merit medals will be certain!

As long as he thought of the sparkling ox fork when he was commended by the whole army, Lukotsev felt that it was very beautiful, and unconsciously took a 180-degree turn towards Bai Yi, how to look at it, how pleasing to the eye, his hand patted Bai Yi's shoulder affectionately, and patted Bai Yi's body so much that Bai Yi's body almost fell apart.

Lukotsev's big paws are full of bear paws, and when they are round, they can break the big tree at the mouth of the bowl, where can Bai Yi eat? Quickly jumped to the side and shouted, "Stop, stop, I said, I'll say it...... Under the influence of high temperature and its changes, the thermal expansion of the inner and outer skin materials is different, and the thermal expansion and contraction of the lower skin structure under the condition of high temperature and drastic temperature changes.

In addition, due to the constraints of the structural connection, the temperature of the inner and outer skin changes unevenly, which causes thermal stress on the components and leads to the structure

The deformation is inconsistent. Structural thermal stress and thermal deformation act on the rivet at the same time.

In the random vibration and noise environment, due to the different rigidity of the components, when the structure with different vibration frequencies is subjected to high-frequency irregular and strong vibration, violent collision and friction will occur between the components, and the rivets as structural connectors are directly affected by it. At the junction of the structure with weak rigidity, thin and not tight connection.

For example, there is a gap between the profile and the skin and between the profile and the rivet that is only connected by two components, or the original gap is accelerated to increase the amount of clearance, and finally the rivet hole is enlarged and the rivet is loosened or falls off......"

Bai Yi almost finished speaking in one breath, but Lukotsev and Pushlenko listened to it more and more, the brighter their eyes became, especially Pushlenko took out a notebook and seriously wrote down every sentence of Bai Yi, but he remembered it, but Pushlenko stopped, not that he didn't want to remember it anymore, but Bai Yi suddenly stopped talking.

This made Pushlenko not react for a while, and urged very anxiously: "Why don't you say it, little comrade?" You go on, my side can keep up......"

"The questions have been laid out one by one, as for how to solve them, you, an experienced pilot, should be able to find the answers, right?"

Bai Yi's voice was not loud, but Pushlenko happened to hear it clearly, and he couldn't help but pause for a moment, only to understand, dare to feel that this is Bai Yi saving face for him, not that Bai Yi can't tell him the final solution, the key is that if he really wants to do this, he doesn't have to take the title of ace pilot.

It would be too vain for any ace pilot to find a solution to the problem when the problem is obvious.

So Pushlenko's old face turned a rare red, and then he quickly nodded again and again: "Yes, this time it will definitely be!" ”

"Boy, good job, this time a MiG-15 pit station can't run!"

Bai Yi quietly woke up Pushlenko, but he didn't think about it, as soon as his voice fell, the same whispered voice came from his ears, Bai Yi was stunned, and couldn't help but look back, only to see the head of the armament standing aside like no one, but the smile that seemed to be on the corner of his mouth seemed more elusive......
