When they came to the workshop, they saw one of the J-8 fighters, the wing had been assembled, and when they came yesterday, everyone was tired, so this wing must have been assembled by American engineers, and it is even conceivable that before they assembled, they might have disassembled the skin, and carefully pondered the frame inside, but anyway, since they have come here, they are not afraid to look at it.

However, the engineer here has a strange expression on his face.

"Thank you very much for helping us install the wings of one of them, and we'll install the other one." Mr. Gu said.

Along with it, there is a special wing in charge of the wing, as long as this kind of wing is hoisted and docked, it can be installed quickly.

Supposedly, once one of them is installed, the wings of the other should be installed in place soon, but now, the expression on the other party's face is still very strange.

"Your fighter planes use a lot of bolts." said to Mr. Gu.

Bolted, isn't that right? Connecting the wings of the fighter with the fuselage, that is, you need to use a circle of bolts, and when you hear the other party's words, it is everyone's turn to be strange.

"We prefer to use quick couplings." At this moment, Pelehak on the side explained to them: "So, our engineers are very peculiar when installing your wings, if we change our way, it will take a few minutes to disassemble the wings, and the design of your fighter is too cumbersome." ”

After all, in addition to the connection of these fixed wings, the wing is also an integral fuel tank, and the wing must be hung with weapons, or there are cables and other devices, which are also connected through quick connectors, and in China, it is still the oldest way before, so that it is very laborious to disassemble and install.

In terms of maintainability, there is a big gap between China and the West, which everyone knows very well, but now, the other party is surprised not by the current point.

"Take your wing as an example, the threaded connection holes of this circle are not standardized, when we installed it, for the first time, we installed six bolts, and when we installed it to the seventh, it couldn't be plugged in!"

Compared with the design of this joint, this ending makes the American counterparts feel very speechless, although the production of fighter jets is different from the production of automobiles, not assembly line operations, but, your standards should be unified, right?

This is really a problem in China.

Generally speaking, the fuselage is produced, and the wings are also produced, so that when the fuselage and wings are installed, the wings are hoisted, and then the holes are drilled with an electric drill, and the screws are installed after they are played, so that the wings are fixed.

Even if there is a general orientation in advance, for example, the wing has a horizontal spacer, between every two spacers, a hole is punched, and it is still in the middle of the two, but there is still a gap, as long as the error is more than one millimeter, the screw hole must not be aligned, and there is no way to stuff the screw.

In China, this is not a big problem, after all, there are too few cases where fighters need to change their wings, and a wing, which is for an aircraft, will definitely not be cobbled together, so it is not a big deal.

However, in the West it is different, their work is more rigorous, if you use bolts, the position of those openings must be precise, so to speak, the wings of any two fighters, removed can be directly exchanged.

Even, needless to say the wings, just the skin of the fighter plane, is riveted by rivets, the position of each of their rivets is determined, casually disassemble the two skins, as long as the position is the same, they can be interchanged, and the points are exactly the same.

China has never asked for this, when installing the skin, it is also an electric drill to punch holes, and then riveted directly with a rivet gun, and, because it is an outcropping rivet, the fighter looks like a patch out of pieces, while the Western fighter plane, the use of countersunk rivets, after riveting, and the skin is flat, as for how much wind resistance this thing can reduce is not clear, at least it looks very beautiful.

Now, when the other party said this, he seemed very incomprehensible, and everyone present had a thought, you can actually screw six screws, it's amazing!

They didn't think there was anything inappropriate, this time you weren't familiar with it, next time you will be familiar with it, besides, we obviously marked the wings, the correspondence has long been found, you don't listen to us, just start the installation, there is a lot of possibility.

The production of military aircraft in China, starting from the introduction of the imitation MiG-17, to now, all aircraft are engaged in this way, and they still take to the air to fight.

Everyone has not yet realized the problem, let alone known, because of this seemingly small problem, which is not written into the contract, has become an excuse for the Americans to raise the price later.

Now, since the other party said this problem, then everyone will help solve it, a few people jumped on the workbench quickly, with the most skilled and fastest speed, and quickly installed the wings, we are all through the factory staff competition, are the best players, this assembly work, that is definitely trivial.

"For the next period of time, we will first study this model to determine our modification plan, the installation location of each piece of equipment, and so on." "We're just worried right now, if you have the same problem with the nose, it's not good for our improvement," Pellehak said. ”

What's wrong with this? Now, no one realized that Mr. Gu patted his chest and said: "Don't worry, our fighter plane, we are familiar with ourselves, if there is any problem, we will coordinate and solve it together." ”

Hearing Mr. Gu's words, Pelehak also smiled: "Yes, if you are all as cooperative as you and leave everything to us, then we can also guarantee the progress, but unfortunately, the other group of you always gives us... Drive a hard bargain. ”

The last idiom, Pelehaq was said in Chinese, the unique tone, causing everyone to laugh, Westerners, many born with a sense of humor.

However, Qin Feng knew that this must have been done by Tu Lao, they had to occupy as much technical say as possible, master the technology, and not turn the Jianqi CP project into a Grumman project, otherwise, they would be able to get rid of their own side at any time, compared to the current hands-off shopkeeper, Tu Lao has paid more.
