"However!" Wang Xuexin said: "I think it has several areas that need to be improved!"
"What?" Vladelov looked at Wang Xuexin in disbelief. This Chinese battalion commander who didn't know the heights of heaven and earth actually wanted to challenge this fighter?
Although Vladelov didn't think "La 5" was that good, he still didn't think the battalion commander in front of him could do anything good.
Most furry bears are very direct, and so is Vladlov.
"Save your energy, comrade battalion commander!" Vladlov laughed: "With this time and energy, you might as well buy us two bottles of wine! Do you have any wine?"
"Yes, of course!" Wang Xuexin replied: "But..."
Wang Xuexin stared at the fighter plane, and then said thoughtfully: "Look at this engine cover. It is made up of at least seven parts, right?"
Vladlov did not deny it. He replied impatiently: "It's thirteen parts, comrade battalion commander!"
Wang Xuexin said: "We should change this engine cover to an overall design. Do you agree with this, Comrade Captain?"
Vladov held the cigarette between his fingers and was about to put it into his mouth when he heard this and stopped and asked: "Why do you think so?"
"Because the overall design will make its appearance smoother and flatter!" Wang Xuexin said as he stepped forward and stroked the dents on the assembled parts, explaining: "Don't underestimate these inconspicuous gaps. When the fighter jet flies at high speed, they will
It will create a lot of resistance. If you are a mechanic, you should understand this!"
Vladlov's expression immediately became solemn, because he knew that Wang Xuexin was right. The outside of a fighter plane should be as smooth and smooth as possible. Any small gap or protrusion would increase resistance or even malfunction of the fighter plane... Yes
The areas of resistance will continue to be stressed, which is not a good thing for a wooden structure.
But after thinking about it, Vladelov replied: "Maybe you are right, Comrade Battalion Commander. However, our current design is the best design because it can save time and effort. You have other methods,
Can it be integrated in a way that saves time and effort?”
Vladelov is right. Integrated design can usually only be achieved with a metal casing. Because the metal casing is castable, it is relatively easy to form an irregular, approximately cylindrical shape to cover the outside of the engine.
If the wooden engine hood is also made into this approximately cylindrical shape, it also needs to be a whole...unless the middle of a whole big tree is hollowed out.
Such a large tree is hard to find, difficult to make, and difficult to accurately size.
If it can be done like this, it might as well be made of metal.
"Maybe!" Wang Xuexin pointed to the hood and replied: "Why don't we divide it into two parts, the upper and lower parts? I mean, we can turn the vertical gap into a horizontal gap as much as possible. Wouldn't this reduce the problem?
Small resistance?”
After hearing this, Vladelov was stunned.
As a machinist, he immediately knew that the plan proposed by Wang Xuexin was correct.
The vertical gap cuts vertically in the flight direction of the fighter plane, that is, the wind resistance will directly act on the gap.
But if it is a horizontal gap... the wind resistance will disappear along the gap, that is, it will be reduced as much as possible.
Vladelov cursed in his mind: "Damn it, these scientists, how could they not think of this!"
However, although he admitted in his heart that he was even shocked by Wang Xuexin's words, Vladelov still pretended to be calm and replied: "You are right, comrade battalion commander! You know, this is a new fighter, maybe...
They (referring to scientists) are already thinking about reducing wind resistance!"
Vladelov was right about this.
Because what Wang Xuexin proposed is actually an improvement plan for "pull 7".
"La 7" and "La 5" are very similar in appearance, even so similar that pilot Hans couldn't tell the difference between the two models "La 5" and "La 7".
The biggest difference is that "La 7" is mostly made of metal instead of wood like "La 5"... "La 7" was put into production in the late war, when Mao Xiong's resources were relatively abundant.
Other improvements are in some small details.
For example, the engine cover just proposed by Wang Xuexin.
However, this improvement was not developed by any scientists... In fact, it can be said that it was, because it was calculated by Mao Xiong scientists to improve the performance of the "Pull 5" after blowing it in the wind tunnel.
Series improvements.
Vladelov's performance was beyond Wang Xuexin's expectations.
After all, Mao Xiong was a big country at this time and China was a weak country.
How could a mechanic from a big country lose face in front of a battalion commander from a weak country like China?
In particular, Vladelov was also a pilot consultant. As soon as he came on, he was taught by a Chinese battalion commander how to improve the aircraft... Do you still want the face of the furry bear?
This is a bit like Sun Erwei's mentality in the early days, but now Sun Erwei has no temper at all.
Wang Xuexin didn't take it seriously. He continued to look at the "La 5", and then pretended to say: "This middle section of the wing, I think it should be adjusted, it should be longer. Don't ask me why, this is just a personal feeling
…Maybe I just don’t like it!”
Wang Xuexin could only say this. He couldn't say that this was the result of wind tunnel blowing, right?
Vladlov did not take these words seriously and thought it was Wang Xuexin who was talking nonsense.
But soon after, when a fighter plane produced according to Wang Xuexin's wishes flew in the sky, Vladelov didn't think so...
It is not difficult to achieve this, because Mao Xiong began to set up factories to produce "La 5" on the side of the Eighth Route Army.
Since it is produced by the Eighth Route Army itself, it is of course possible for Wang Xuexin to give some suggestions and make some minor changes.
At that time, Vladelov and Maoxiong's technical staff were strongly opposed because they all believed that Wang Xuexin was insisting on making arbitrary changes.
Vladlov also said angrily: "This Chinese battalion commander, does he think that the longer the wings, the better? Then why not make the wings a few dozen meters longer?"
However, when Wang Xuexin's improved fighter jet flew into the sky, everyone was silent.
Because although it has increased some weight, its flight speed and load capacity are much greater than those of the prototype.
This result made Vladlov and all the technical staff of Mao Xiong unable to believe it.
"How did he know about this improvement plan?" Vladelov exclaimed: "Is it really just relying on imagination?"
Wang Xuexin responded: "It's not all about imagination! We also have excellent aircraft design experts!"
