When Lu Qing arrived in Zhongli, it was basically decided that Zhang Lan had become Mo Beiyizhu and the future son-in-law who had an official name, but had been recognized by Liyan's mother and Teacher Mo, and Mo Liyan, the girl, also became the daughter-in-law of Zhang Lan's official engagement with Zhang Jiahaibo, but these two people were still too young. The current situation is not suitable for engagement, and it is estimated that with Zhang Lan's dislike of having people restrained by her side, it is relatively fast for the two to get married in the old years.

Inner years. Well, two by then. People are all 10,000 years old, according to the current saying of late marriage and late childbearing, the man has to get married in long live, although the woman can get married when she is one year old, Zhang Lan's age of marriage is good on the Internet.

Regarding the fact that Zhang Lan wants to go to No. 1 Middle School to take care of Mo Liyan every day, the four little girls in the family are all very envious, especially the little Chenxi who has been Zhang Lan since childhood, and she is even more envious: from childhood to adulthood. It's all about holding this kid in the palm of your hand as a treasure, who has this kid taken care of? Look at the present. What kind of virtue does this little girl called Mo Liyan have to let such a big young master take care of her in front of the hospital bed all day long, and there is that puff of green smoke on their grave

Is it?

A few little girls always itch Mo Liyan's hateful teeth whenever they talk about it, but the words are beyond the words. It's more of a thought: Alas, how good would it be if the object of that kid's care was replaced by himself?

Of course. What made a few little girls feel most unhappy was not that Zhang Lan had to take care of Mo Liyan, but because: How did this girl become Zhang Lan's nominal girlfriend? So where are we put in? Yes, that's right. Because of the particularity of his identity and physiology, it is probably impossible for him and Zhang Lan to have an official name in this life, but no matter what, it is not impossible to think of a way. But she can't leave the smoke, how can she be able to cut in front of her?

The problem is that Zhang Lan really can't explain this matter. But Zhang Lan, who felt that she was ashamed of a few little girls, also felt sorry for these four little girls in her heart, well, it is estimated that Hu Ruoxi's little girl in Beijing will be counted. So every night before going to bed. Zhang Lan always found that the skin under her ribs was blue and purple.

It is not only Xiao Chenxi, Alice, Jill and Xiao Beibei, who are envious of Mo Liyan and Teacher Mo's family, but also those who are envious and jealous.

Zhang Lan went in and out of Teacher Mo's house all day long, contrary to the normal situation that the kid can't see each other in the school a few times throughout the year, so naturally he can't hide it from the eyes of the teachers in No. 1 Middle School, everyone originally thought this thing was strange, and then thought about Mo Liyan's girl who was idle and had a rash, combined with Mo Liyan's parents' attitude towards Zhang Lan running to their own home, where might everyone not understand what was going on?

The middle-aged female teachers who originally envied Liyan's mother for giving birth to a good daughter are even more uncomfortable in their hearts: it is better to teach well than to be born well, look at yourself, after a hard year, I have to worry about the gray hair of the annual selection of outstanding teachers, and if I don't do it well, there will be no bonuses or anything; Look at Teacher Mo's family again, they gave birth to a good daughter and hooked up with the most awesome family in our county, now even if their teaching performance is the penultimate one, does the principal dare to deduct a penny of bonuses? Not only did you not dare, but you also had to find ways to give more to others. What a world!

Even Principal Wang was shocked, this is not surprising, Zhang Lan goes in and out of the teacher's dormitory area of No. 1 Middle School every day, although he did not meet Principal Wang, but Principal Wang's henchmen did have a few of them who were in the same building with Mo Liyan's parents and parents, and when they encountered such a thing, several henchmen would naturally tell Principal Wang such a thing, and one of them even shook out the fact that he saw Zhang Lan's parents all come that day.

The principal of the county education bureau is also the director of the county education bureau, and the administrative level of the deputy county level even makes Principal Wang more confident in front of the director of the county education bureau. Speaking of which, he can be regarded as a figure in the system. And compared to the other deputy directors and directors in the Education Bureau, Principal Wang of No. 1 Middle School is much stronger. After all, the principal of No. 1 High School has the best educational resources in the county. This is something that no other deputy director or director of the county school bureau can compare.

For the other meaning implied by the incident that his henchmen told him, he naturally saw it more clearly: this matter, eighty percent of the Zhang family nodded to the matter between the girl of the Mo family and the only son of his own family, and the little girl of the Mo family jumped on the branch and became a phoenix overnight.

There is a faint envy in my heart: it would be nice if I could get some light on this. Alas, why are their youngest daughters already married? You girl can't be born late. More than ten years? Can this be born later?

After pondering and understanding the other meaning of this matter. After Principal Wang went to Mo Liyan's house to see Mo Liyan once, he began to ponder. How can I get as much benefit as possible from this? Or, I recognized the little girl of the Mo family as my goddaughter?

Well, this is a good idea, as long as he becomes Mo Liyan's godfather, don't dare to say anything else, at least if other people in the county system know that their goddaughter is the future daughter-in-law of the Zhang family, no matter what they say or do, or even whether they want to deal with themselves, they have to think about it, right? Well, this matter must be solved after Mo Liyan, the little girl's rash is completely cured this time.

On the other hand, Zhang Lan's kid, this kid, is very happy, running around outside all day long, going wherever he wants when he is bored, it looks very chic, in fact, it is very tiring to go back and forth, it is not bad to take a break during this time, anyway, it doesn't take long to take care of the girl, it's nothing more than those few things. Taking advantage of this free time, Zhang Lan did not read the newspaper less, after knowing that Zhang Lan liked to read the newspaper. Principal Wang even asked his correspondent to send a copy of all the newspapers and magazines in his school to Mo Liyan's home, such as "People's Daily", "Guangming Daily", "China Youth Daily", "Reference News", "Global Times", "Qiushi" magazine, "Reader" magazine, "Youth Digest", etc., whether it is within the party or outside the party, but all the miscellaneous things in the school, regardless of 3721, send a copy here, even if you know it. Yulan likes military magazines, and then the principal of each other ordered her to pass her staff, and sentenced all the military magazines and newspapers in the street newsstand to buy a copy, which is a bit of a chance to tie this kid up, and you can't find a chance to be close to this kid on weekdays. ,

Of course, while taking care of Mo Liyan and reading the pile of newspapers and magazines in the house, Zhang Lan did not forget what she was going to do, after spending the initial depression, Zhang Lan pulled Xiao Chenxi and Xiao Beibei together, don't get me wrong, the purpose of pulling these two little girls is not to take care of Mo Liyan. Instead, while taking care of Mo Liyan, he discussed with Xiao Chenxi some business and product research and development issues in his aircraft manufacturing company.

As for Little Beibei, it also seems. It's not because she knows such a profound knowledge of aviation manufacturing, but because this girl is here to supervise whether Zhang Lan and Xiao Chenxi will "guard and steal." Target. When she heard this girl confidently tell her reason for coming, Zhang Lan could only cry and laugh.

As for Alice, this girl. Naturally, she wanted to come, but because she had the title of president of Alice Group on her head. Naturally, you can't "condescend" to come to this "very simple." squatting, that was too unusual, so I had to go to the group to stay in her luxurious office aggrieved, but it was okay. As long as Xiao Chenxi and Alice are interconnected through the network, Xiao Chenxi will make a three-dimensional projection of Alice's figure and project it in Mo Liyan's home, and the effect will be the same with a few people discussing these issues together.

In view of the fact that Mo Liyan, the girl, is basically in a coma all day long, Zhang Lan, Xiao Chenxi, and Xiao Beibei are discussing these things in the living room, in order to prevent the little girl from waking up suddenly when she is discussing hotly, Xiao Xiao Chenxi also placed a video monitor and vital signs monitor in Mo Liyan's house, as long as Mo Liyan wakes up or the potion in the drip bottle is about to be replaced, she will immediately call the police to Xiao Chenxi, and Zhang Lan will immediately go in to take care of the little girl, Usually, a few people discuss these issues outside, but they don't delay taking care of Mo Liyan, a little sick number. Not to mention, with Mo Liyan's sick number threatening Xiao Chenxi, Alice and Jill, the speed of the little girls is really quite fast, and when discussing the tiltrotor that was originally designed in Belgrade, the capital of Yugoslavia, this advantage can be reflected in the drenching dutifulness.

Like the vast majority of military aircraft, this tiltrotor is also designed as an upper monowing layout, compared with the commonly used lower monowing or fancy monowing of civil aircraft, the layout of the upper monoplane can not only ensure that the aircraft can avoid the sand and dust on the ground being sucked into the engine when landing at the temporary airport, greatly reducing the life of the engine, and it is also convenient to maximize the cargo compartment of the aircraft in the limited space, and the cargo hold is close to the ground. Naturally, it's easier to get on board.

As for other advantages, such as easy to maintain the continuity of cargo space, easy to rationally use cargo space, easy to observe the working condition of the engine, convenient for personnel and equipment airdrop, etc., there is naturally no need to make superfluous statements, after all, the main customer of this aircraft design is the military. As for the many advantages of the single wing, I'm sorry, although there are many rich people in the world, but there are really few people who can be extravagant enough to be able to spend a lot of money to sell such an aircraft.

"To be changed. Type double vertical tail?. Xiao Chenxi repainted on the plane projected by himself in the form of three-dimensional projection in front of him, so that he did not change the vertical tail of this tiltrotor to a single vertical tail at all. In the hope that this aircraft looks more like a product from the earth, rather than a high-tech product that has been ahead of the ball for many years. "Although the stealth performance of the shape of the camber double vertical tail is not bad, but at the speed of this aircraft, is it really necessary to use the shape of the vertical tail? The ordinary vertical double vertical tail is about the same, right? ”

"This" our aircraft still has to take into account the stealth performance after all. Zhang Lan scratched his head, "Although the current helicopter is not much different from stealth performance because of its relatively slow flight speed, the flight speed of our tiltrotor is almost twice that of an ordinary helicopter, and the camber vertical tail is not at right angle to the horizontal tail, which reduces the angle reflector reflection of radar waves, which is conducive to stealth, and compared with the traditional vertical double vertical tail, the aerodynamic performance is not bad, at least when climbing at high angles of attack, Aircraft with a shaped camber vertical twin tail are aerodynamically more efficient than those with a traditional vertical twin tail. If we take into account the stealth performance and aerodynamic efficiency of the aircraft, doesn't it mean that our aircraft can be sold at a higher price? Well, although we don't encounter many cases of tiltrotor climbing at high angles of attack. But what if you run into it? ”

Of course, for Zhang Lan, the reason for the use of the outward camber vertical double vertical tail is not the above, but that Zhang Lan's small, Zijue royal double vertical tail is better than the traditional vertical double vertical tail, at least compared to the clumsy horizontal tail and vertical tail integrated design scheme on the left Osprey tiltrotor is a little more handsome.

Cheng Xiao Chenxi and Alice nodded at the same time, for them, what kind of vertical tail and flat-tail layout this aircraft has. It doesn't matter much at all. They always find a solution that brings out the best in the aircraft, "and that's a full-motion flat-tail and double-vertical tail layout." ”

"Is this it?" After making some slight modifications, changing the original vertical tail and flat tail design to what Zhang Lan said, Xiao Chenxi asked.

"Well, that's what it looks like." Zhang Lan nodded, looking at this tiltrotor that had been modified by Xiao Chenxi and Alice. Well, this vertical tail and flat-tail layout looks much better than the original, "How's the aerodynamics?"

"It's okay," Xiao Chenxi said, and began to use simulation technology to simulate the wind tunnel model test of the aircraft. The test data of the simulated wind tunnel test is constantly projected next to it, but unfortunately Zhang Lan can't understand most of the data, "After adopting this new tail aerodynamic layout, the overall aerodynamic performance of the aircraft has been improved, and the climb performance at the high angle of attack has been improved?" The end is quite good, the only problem is the structure of the full-motion vertical tail and flat tail, the structure should be slightly double... Some, of course. The cost is also relatively high

"This is not a problem, if someone dislikes the high price in the future, we can withdraw from a simplified version. When the time comes, there are good ones who want to be good, and there are ordinary ones who want to be average, and they can choose according to their preferences. Well, I don't have anything to say about this part of the fuselage, the original design purpose of this tiltrotor is to make the aircraft as close to the battlefield as possible and provide enough support for the battlefield" Zhang Lan stared at the picture projected by Xiao Chenxi, and said without blinking his eyes. ,

"Aren't you afraid that the Americans will talk about patented technology again?" Alice's eyes rolled and asked slyly.

For example, the Americans were the first to develop the atomic bomb, and it is said that in terms of the technology of nuclear weapons such as atomic bombs and hydrogen bombs, the Americans have the most complete patented technology, but can they accept the nuclear weapons technology of the former Soviet Union and China? Of course not.

In the same way, this principle also applies to many aspects of weapons research. Even if you want to charge other people's patent fees, whether people are willing to let you take his products for patent appraisal or one, the problem of military technology, that is related to a country's military secrets, and aviation technology is a military secret among military secrets, who is willing to take out their own country's secrets, I haven't seen the United States and the Soviet Union during the Cold War, the two countries are all desperately trying to get each other's aviation agency equipment, the former Soviet Union defected to the United States of the Migvan, Isn't it just causing a huge sensation in the United States?

"Cut" Based on his understanding of these things, Xiao Zhang Lan snorted with disdain, "It's just in the ordinary civilian science and technology field, but in the military science and technology field?" Patents are a bit of a hair, in the future, we can also say that the Americans have stolen our technology, by the way, sister, in the future, all the software on our plane will be encrypted, don't let the damn United States come out of the anti-axe, don't look at the Americans seem to pay a lot of attention to copyright and patents, in fact, in front of real good things, Americans are not good birds. ”

If the Americans were good birds, they would not have taken the MiGs of the former Soviet Union? The 5 fighters were dismantled and carefully studied for several months before they were returned to the people, for which Zhang An had every reason to despise the Americans.

"Yes, Americans are indeed not good birds, Xiao Chenxi and Alice couldn't help but smile and nodded, "Leave the matter of software encryption to us, it's not a big deal, I guarantee that they can't crack it." ”

"That's done. By the way, the wing shape of this aircraft, don't want this kind of straight wing, although the straight wing is really good at low speeds. But wouldn't it be better to switch to a forward-swept wing? ”

"Forward-swept wing?. Xiao Chenxi and Alice glanced at each other, with some surprise in their eyes, "Is this necessary?" Although the forward-swept wing shape can greatly improve the aerodynamic performance and surface load and surface energy of the aircraft during low-speed maneuvers. It can even greatly improve the take-off and landing distance of the aircraft, and it has the incomparable advantages of the traditional swept wing shape when used in a small base or a mobile base at sea, but the advantage of the swept wing is more reflected in the transonic speed. "Hmm. Not to mention, if you use a forward-swept wing for this aircraft, will it cause any problems with the installation of the engine and the center of gravity of the aircraft? Are there any problems with the difficulty of production, the structure of the wing and the weight of the wing itself, and the combination of the wing and fuselage? Zhang Lan thought about it and cautiously asked this question.

"The center of gravity is not going to be, as long as you pay a little attention to the design, pay attention to the age of the wings and engines, even if the movable engine nacelle structure is adopted, it will not have any impact on the center of gravity of the aircraft" Xiao Chenxi has quite a lot of this.

"As for the other three aspects you mentioned, there is no big problem, our company's current composite material technology is relatively mature and small, although the composite skin that can be used for the surface of the wing is not yet good, but as long as we provide technical guidance, this is not a big problem, as long as the composite materials are used, not only can the production difficulty be reduced, but also can greatly reduce the weight of the wing," Alice added, "As for the wing-body fusion technology you are worried about, This is even more problematic, as the forward-swept wing shape has a greater advantage than the backswept wing in this respect.

Zhang Lan was ashamed for a while: Niang Xipi, I only remember that the shape of the forward-swept wing was quite awesome, when the old Maozi's Su Xiao "Little Golden Eagle" forward-swept wing technology verification machine network was launched, the whole world will blow this kind of airfoil, it seems that this thing is awesome in the future, this is to replace the traditional swept wing airfoil When I thought these guys were bragging enough, I didn't expect this. Things are actually better than what is advertised in the media.

"The flight speed of our tiltrotor is not very high, on the basis of the existing hardware equipment and the improvements that have just been made. With the forward-swept wing shape, you should not encounter "aeroelastic divergence." Questions, right? Well. In terms of technology, the technology of the swept wing is more complex than the swept wing, and the relevant technical requirements for supporting it are relatively high, the strength of the aerodynamic components is required, and there is also the problem of wingtip flutter. Hearing Xiao Chenxi and Alice say this, Zhang Lan was completely moved, but she felt a little strange. These two girls don't seem to be trying to persuade themselves not to use this technology, but they seem to be encouraging themselves to use this technology.

"These are not problems" Xiao Chenxi and Alice's eyes flashed with a hint of pride at the same time, "The only problem we are worried about is that so many advanced technologies appear on this plane at the same time, will there be any problems at that time?" small

"Damn! Is this a Mao's problem? There are so many new technologies appearing on the same plane at the same time, which means that our technology is good! If you want to be a blockbuster when the time comes, you have to take some extraordinary measures. Didn't say it, then use the forward-swept wing. Anyway, the flight speed of this aircraft is not very fast, and it requires good stability in low-speed flight, and it is suitable to use a forward-swept wing. Zhang Lan gave a slap on the board.
