"Yang Group, it's a good thing, after waiting for so long, I can do a project with you, and everyone hopes that under your leadership, we can blow out an excellent aerodynamic design."

As soon as Liu Jun returned to the base, he got the news from the chief engineer that the new aircraft pre-research was about to be launched, which can be regarded as making Liu Jun very happy.

Later, when he heard that Yang Hui would coordinate the overall aerodynamic design of the new aircraft, Liu Jun didn't say much, Liu Jun had already understood the situation after the base, and these leaders of the older generation were obviously training Yang Hui to be the next leader.

Now and Yang Hui into some, the pneumatic design team can get more support in the future, and at the same time, it is also counted as Yang Hui's strong recommendation two years ago, plus this time it is to cooperate with the Americans, and Yang Hui needs to be reconciled with people like Yang Hui who often deal with foreigners.

The team that came back with Liu Jun is much larger, definitely not only the ones that Liu Jun took away last time, but also because the strength of the base has increased now, the country has paid more attention to it, and human resources have begun to invest more than before.

There is Liu Jun once again repeating Yang Hui's feat two years ago, which can be described as "re-walking Yang Hui's road", returning to the imperial capital alma mater, how can he leave Baoshan without bringing something.

first showed up with the juniors, and then begged the tutor softly, and promised to take care of the juniors and sisters when he arrived at the base in the future, and finally let this guy drag the family back more than ten people.

Yang Hui has to admit that this Liu Jun is very talented, the most important thing is that he is thick-skinned enough, not to mention, this thick-skinned person can always get some benefits that others can't get.

Take a look at the dozen or so new faces in the back. Yang Hui was very satisfied, and at the same time a little emotional. Now the pneumatic group of the base is completely occupied by the students of Beihang University. It seems that one day I will have to go back to Xi'an University of Technology to dig well, and Xi'an University of Technology aerospace will not be weaker than Beihang.

"Hello everyone. In the future, they will all be a family, and if you have something to ask your seniors here, they are all old fritters, don't be polite. ”

After briefly getting to know these new students, Yang Hui and Liu Jun walked aside and asked about the wind tunnel test of the big side strip wing.

"What's going on? According to the theory we came up with last time, the data should not be problematic, and the problems in your test should be described in detail. ”

It's okay not to ask here, but once you ask here. Liu Jun felt that this wind tunnel test was quite aggrieved, and now that he thinks about it, he still feels a little confused.

I recalled all the situations during the test, carefully recalled all the blowing processes, and said them word for word.

"In our tests, we found that the large edge strip wing can indeed produce strong eddies, and as the angle of attack increases, the resulting eddy currents will continue to increase, and the lift changes smoothly, but our pitch trim ability will become the biggest shortcoming at this time."

Not a lot of words. The good news is that the advantages of the big edge strip technology do exist, but the bad news also follows, and it is indeed difficult to get the pitch trim right.

Yang Hui couldn't figure out what the situation was for the time being, so he could only listen to Northrop's opinion first. Maybe there's some good advice, and that's the best outcome.

"Let's go, let's go and see how the Americans solve this problem. I believe this problem is not unique to the big side, and Northrop has definitely encountered this situation. ”

Yang Hui really guessed correctly. Northrop has really encountered this situation, and the solution to the problem is that Yang Hui is overwhelmed.

Liu Jun knew that a team of American aerodynamic engineers had arrived at the base. I can't wait for a long time, what is unique about the aerodynamics of the Americans? After all, it is the side that can compete with the Soviet Union, and now Liu Jun has to learn from others.

"So, we can go and discuss with the American side now, and the purpose of their coming here is to assist us in solving technical problems, and then we can develop subsystems for new aircraft."

Obviously, Yang Hui has reversed the priorities of Northrop coming to the base to cooperate, and Northrop is coming for the new plane, otherwise who will bird you.

Walking into the office specially arranged for these Americans, these Americans are actually playing poker there, this is really unbearable, we are in a hurry, you are still playing poker here.

Slapping the table stopped these Americans from continuing their leisurely lives, and the big landlord Yang came to urge him to work.

"Brown, hurry up, there is a problem that needs to be solved by you, our company's pneumatic designers have returned, and you can see our company's technical capabilities immediately, but you also need to solve a problem."

Brown and his party, who had been idle for three days, had already passed the jet lag, and they were waiting for Yang Hui to take them to see the aerodynamic level of the republic, and now that they had the opportunity to understand the aerodynamic level of the republic, Brown stood up and left.

"We can't wait for a long time, and it's hard for us to hold on in this place where there are no basic entertainment venues, without the paralysis of work."

With a group of Americans, I came to the big office, and a lot of materials and questions were already on the table.

Just waiting for the great god of the United States, the birthplace of the aviation industry, to answer, a pair of ** eyes, these eight Americans look creepy, this is a typical number of people, bullying the small.

Fortunately, they are all people who are engaged in technology, and their nerves are more or less big, and after a short time, they got used to it, and began to focus on Yang Hui, waiting for Yang Hui's introduction.

It's a pity that Yang Hui didn't plan to waste saliva to introduce, only let these Americans see the strength of the base first, as for the introduction, it is not necessary, and it will be recognized slowly later, there is no need.

"Let's take a look, we started working on the edge wing technology before you came, and now we have a problem, maybe you can give the right answer."

Before he finished speaking, Yang Hui handed the problem data to Brown, there is no need to keep this thing secret now, just look at it.

The same is engaged in aerodynamic design, before this time Brown and his entourage also read the accompanying side wing information from a new one, and they are no strangers to the aerodynamic data of the side strip wing. You could tell what it was at a glance, but it wasn't that that surprised Brown the most.

When you pick up the information and observe carefully, the more you look at it, the more frightened you become, this has conquered the big edge wing technology, and what do you want our ordinary side wing technology to do?

It's not a joke to me, these plain data are rigorously supporting Brown's conclusions. Putting down the information, Brown was depressed, what was going on

"I have to admit that your technology has reached the peak of the edge wing, and this is the case with the large side wing technology that we just completed in Northrop, and your wind tunnel data is not much different from ours. You can start to prepare for the transformation of a large side strip wing technology verification machine, which we have also tried in Northrop. ”

Brown's words sounded quite exciting to others, and he directly reached the level of Americans, but Yang Hui and Liu Jun sounded wrong.

What are the Americans talking nonsense? Obviously, the pitching moment trim of the large side strip wing is a big problem, but the Americans say that there is no problem with the data, will the Americans not find this problem?

Liu Jun was the first to speak, if the Americans couldn't even see this, then Liu Jun would completely despise the aerodynamic level of the American imperialists, and even wonder how the prosperity of the American aviation industry came about.

"No, we've found a fatal problem with the big side wings, which makes pitch trim more and more difficult as the elevation angle increases, as you know for sure!"

Brown was confused, and the other seven couldn't figure out what was going on, and everyone knew about it, but the problem was that the United States had other ways to make up for the difficulty of pitch trim. (To be continued......)
