"What do you think of the shape of the planes. The more you look at it, the more it looks like a chubby version of the parent "Four 1 fighter?" After a series of improvements. Zhang Lan couldn't help but start thinking about the three-dimensional diagram made by Xiao Chenxi: Well, there is no duck wing at the front, and the overall aerodynamic layout is not uniform. Of course. Although Liu Nail is a technical verification machine. But after all, the design prototype is a fighter jet, which is fundamentally different from the transport tiltrotor designed for multi-purpose use.

"Well, with this all-new aerodynamic layout with a flat-tailed tail and a swept wing. How fast can our plane fly? "Zhang Lan asked-'This speed needs to be carefully calculated, not only the power of the engine, but also the efficiency of the propeller fan, the energy of the wings and the overall aerodynamic shape of the aircraft and many other conditions related to flight speed. Getting around is quite difficult, or almost impossible.

"If it is unloaded, Xiao Chenxi quickly calculated the new flight speed of this aircraft after replacing it with a new vertical tail and horizontal tail structure, as well as the most important main wing structure." Cruising speeds can reach kilometers per hour. The maximum flight speed can reach every kilometer per hour, which is quite close to the speed of a large strategic transport plane or a large passenger plane, and is the same as the Americans' 1 ugly "air Hercules." Tactical transport aircraft and domestic Yunfang tactical transport aircraft, which are also tactical transport aircraft using turboprop engines. It has an absolute advantage in speed and flexibility of take-off and landing. Jintong's helicopter is naturally incomparable with our tiltrotor aircraft, the Americans. Five "ospreys." The reconnaissance plane can only bow to the upper hand. Well, it wasn't originally designed to be a medium tactical transport aircraft. Therefore, the carrying capacity is worse. ”

"We're not going to use this guy as a single transport plane, are we?" Zhang Lan smiled almost from ear to ear, "If it's just used as a transport plane, our baby will be a little more talented." Pull and take a look. Domestic aircraft capable of carrying more than 1 plus weight can take off and land vertically and hover in the air. Not yet. ”。 Zhang Lan still knows how widely the uses of the Tan "Osprey" tiltrotor are, and the use of this thing is naturally only a wider extent.

Zhang Lan can even optimistically estimate that as long as the flight deck is expanded, this thing can even be used as a carrier-based aircraft for large frigates and destroyers, and the role that this thing can play in the navy is much greater than that of the Zhi-8 carrier-based helicopter and the Zhi-9 carrier-based helicopter currently used by the navy.

"After a redesign of the aerodynamic layout, the payload of this aircraft has increased slightly. The result of the calculation just now is that if the take-off method of short-distance taxiing is adopted, the run-off distance is 1 Wum, which is shorter than the short-range take-off and taxi-run distance of the American ugly osprey tiltrotor. This has a great advantage in small and medium-sized aircraft carriers. Alice added.

"Then if you add that this plane is relatively fast and has a relatively large load, it can be used as a short-range bomber or when the ground firepower is not very strong, and it can be used as a strong attack aircraft?" Hearing Xiao Chenxi say so much, Zhang Lan couldn't help but say this.

"When necessary, it is indeed possible to do so

Xiao Chenxi didn't object to Zhang Lan's words, Xiao nodded seriously, and analyzed the shortcomings of Zhang Lan, "But if you really let them use it as a front-line attack aircraft, it won't be too suitable, one is that the armor thickness is not enough to withstand the blow from the ground anti-aircraft fire, and the other is that the volume of this thing is too large." The goal was too obvious, after all, this was a model that was originally designed for transportation, and the innate conditions limited the scope of use of this aircraft. ”

That's true, but think about it, even the Americans' aircraft and carriers need things like helicopters, and the use of such planes is even greater, right? Just saying that this aircraft has the same vertical take-off and landing capabilities as helicopters, but compared to helicopters, it has a much longer range and much faster flight speed, and it is not impossible to use it as a tactical transport aircraft, the only problem is probably that

"Sister Alice, do you have anything else to add?" Zhang Lan asked Alice for advice.

"There is a point, because of the forward-swept wing shape, the wing surface load has increased a lot, and if it is just wasted, it will not be worth it." Hearing Zhang Lan ask herself. Alice made a new suggestion to Zhang Lan on the side, "Is it to consider adding a few external attachment points under the wings, which can be used to hang auxiliary fuel tanks to increase the range, or increase the small load capacity without increasing the overall weight of the aircraft and changing the overall aerodynamic shape of the aircraft." Or even carry a little weaponry when necessary? ”

This is a good idea, Zhang Lan also has to admit that Alice's words are very reasonable, if after changing to the forward swept wing, because of the unique shape structure of the forward swept wing, the extra part of the "mound load" is so wasted. It's really a bit of a no-brainer. "If you do it the same way Alice did. It is not a good way, especially when carrying some things that are relatively large in size but not necessarily very large, you can also choose to plug in the outside of the fuselage to save the limited cargo compartment volume in the aircraft body. Among other things, the mere fact that you can carry enough fuel to add a considerable range to the aircraft is tempting enough.

"Well, it's good, let's add this as well," Zhang Lan felt that this matter made a lot of sense, "After all, many countries do not have the ability to carry out air refueling operations anywhere in the world, such as if the fuel recommended by their own planes can fly far enough, this is not a good choice." ”

It is indeed good, Xiao Chenxi also nodded, and agreed with Zhang Lan's statement, especially now, some "countries" in the world do lack overseas military bases, and the premise is flat without the support of overseas bases. Being able to fly the plane far enough is so small that it's too important. ,

"Is there anything else to add?"; Bu Chenxi turned his head and asked Zhang Lan, "If not, then I will have to finalize this aircraft based on these existing things?" ”

"That" how is the research work on the propeller fan engine and the horizontal pair of the propeller fan now, if everything is ready in the end, but in the end it turns out that the power of the aircraft is not keeping up, then the fun is really great.

For the research of the aero engine on this tiltrotor, Zhang Lan couldn't help but raise new questions.

"This, now that you are doing it, I know that you must not be able to help but ask this question Xiao Chenxi pursed her lips and smiled, "The research work on the rotary paddle fan at the level required by the paddle fan engine is already in the final stage of laboratory research, and it will not take long to transfer to how to carry out actual industrial production." ”

"Well, the research work on the paddle fan is nearing completion, and the entire paddle fan is made entirely of lightweight composite materials, which is not only lightweight. The low cost and easy control of the shape of the paddle fan have also performed quite well in the experimental performance of the mechanical strength of the paddle fan and the high and low temperature resistance of the paddle fan. "Speaking of which. Alice herself is also very proud, the paddle fan engine that can be put into use can appear in her own hands, and get the affirmation of Zhang Lan, the little guy, Alice's heart is still quite satisfied, "The next thing to do is to test the anti-aging ability of the paddle fan, as long as there is no big problem in this piece, then there is no big problem."

"Damn!" Zhang Lan couldn't help but burst out with a foul word: Even if it is an American with deep pockets, researching the ugly "Osprey" tiltrotor, from the beginning of the project in 1 year to the official procurement of the military in the blade year, it has also experienced a whole old year, although there is not so much time from the establishment of the project to the start of the test flight, but the time is also more than the old year, and he has this super tool, and he can shorten the time to less than two years. It's a super miracle - although even if it is built, it may not be stunned that there is a purchase order from the military, but as long as your plane flies at the world's major air shows, it will be an absolute star. In this regard, Zhang Lan has full confidence: even the Americans have not yet fully mastered the technology, and now that the Alice Group has a product, it is strange not to surprise those guys' eyes and jaws.

Zhang Lan didn't ask how long it would take to officially come up with the product for herself, anyway, it wouldn't be very long, at most, and there would be no problem with taking out a few prototypes for herself at this time next year. If Xiao Chenxi and they reached out indirectly. It's not surprising to see the plane's first test flight this year.

Time passed quickly and hecticly, and by mid-June, the inexplicable legal battle between China and the United States had finally come to an end, though not perfectly.

More than a month has passed since the US military "mistakenly bombed" the Chinese Embassy in Yugoslavia, and after the two countries have experienced an extremely cold period in their relations, mutual exploratory contacts, and formal negotiations, a series of preliminary agreements have finally been reached on the "accidental bombing" incident:

The US Government publicly apologized to the Chinese people for the damage caused to the feelings of the Chinese people in this accidental bombing. In this "accidental bombing", the Chinese government was compensated 11 million US dollars for the property damage caused to the Chinese government; Compensation of US$140,000 was made to Liu Kemei, Zhou Yao, and Cheng Pengyun, the three martyrs who were unfortunately killed in the "accidental bombing", and many other embassy staff who were injured; As a complement to the relationship between the two countries, the U.S. government will open up some of the technology and equipment that was previously embargoed to the Chinese government, of course. It is the kind of technology and equipment that is not very sensitive, and as for whether it is to open up those technologies, this is still under further discussion. Work together to create a bright future for the relations between the two countries.

It is a very formulaic compensation agreement, and even this is only a preliminary agreement, although theoretically it is unlikely that there will be any "big moves". But as long as the matter "the day has not yet been finalized." Then it's anyone's guess, after all, it's just one. Isn't the preliminary agreement?

Compared with the historical compensation agreement in which the Chinese government compensated the Chinese government for the tens of thousands of dollars and the embassy staff who died and injured in the "accidental bombing" in the amount of tens of thousands of dollars, the amount is obviously much higher. However, compared with history, time is much faster, and the time in history was made by the United States team in January of the same year, which lasted more than eight months. This time, however, a preliminary agreement was reached in just over a month, and at this time in history, the two countries were still at a point where neither of them spoke to anyone.

Zhang Lan commented on this, whether this compensation is good or not, after all, this compensation is only superficial, and he has not participated in it, as for whether the two countries behind this compensation have reached any agreement, this Zhang Lan is not clear. Although as long as you want to know, you can find out with a little inquiry. But Zhang Lan didn't mean to inquire: he had already created such good conditions for the domestic side. If you can't catch it in the country, cough cough, then it's better to bow yourself than you don't know. lest I be even more depressed at that time.

For this. The initial compensation agreement was naturally unanimously reached on television, newspapers, magazines and other media, believing that the Americans had made this unprecedented compensation as a victory for the Chinese, but the Internet with a higher degree of freedom and openness did not seem so calm, and there were many people who broke the words and cursed this compensation condition. It seems that some people have signed this compensation agreement, and the current government is the government of the late Qing Dynasty, and whoever signs it is the traitor Li Hongzhang.

For these voices on the network. Zhang Lan also only sighed: Maragobi's, the current living conditions are good, when the river crab and donkey dam have not yet appeared, the creatures living on the grassland of Malagobi are still so carefree, but after a few years, when the mythical beast river crab appears, there is no place for you to jump here on the grassland of Maragobi, the dignity of the mythical beast is inviolable, and the sound of the mythical beast river crab can only be heard on the Malagobi grassland. You are much happier now than the Maragobi creatures who were ruled by the Divine Beasts a few years later. ,

Of course, these have little to do with Zhang Lan now, as time slowly passes, Mo Liyan, the little girl, has already stopped the needle, and her body is no longer feverish, although her body is still very weak, the little red bump on her face has not completely dissipated, although the little girl can't see the wind now, even if she is active, she can only walk around in the living room or be supported by Zhang Lan to walk around the various rooms in the house, but this can not reduce Mo Liyan's excitement at all.

In the words of this girl, in the course of a month while lying in bed, mushrooms are almost growing on her body. Because she couldn't see the wind, Zhang Lan helped the girl to walk in the corridor, according to the girl, when she went up the steps, there were still bursts of blackness in front of her eyes, and you can imagine what the little girl's body has been tossing into this month.

But that's not a problem, after all, I've survived this month, and it's like shedding a layer of skin. The only problem is that there is no good solution yet, so I can't take a shower and wash my hair, think about how terrible it is to think that I haven't taken a bath and washed my hair for more than a month, and this kind of thing happens to a little girl who thinks she is beautiful. So much so that every day when Zhang Lan came to see Mo Liyan, this little girl always hid in her room timidly and was reluctant to come out, and every time she needed Zhang Lan, she needed to beg in front of the door for a long time in a low voice.

Now Mo Liyan's biggest wish is that he can take a good bath and wash his head.

Zhang Lan has been around Mo Liyan, the little girl, and has been working tirelessly to take care of her for the past month, although the little girl is burning very badly. But it's amazing that I should remember it very clearly, if there is no little sweetness in my heart, it is impossible, the girl's feelings are always very romantic, and I always hope that I can meet a prince riding a white horse to take him away.

Although Zhang Lan drives a huge black Humvee every time he comes, he has a bit of the smell of a black coachman, but fortunately, this black coachman treats him relatively gently, and the coachman's appearance is still a little handsome. What a cheap one, bastard. Whenever he thinks of this, Mo Liyan can't help but draw a beautiful arc at the corner of his lips.

The matter between himself and Zhang Lan. Mo Liyan already knows. It was probably the few days when this girl stopped the needle, and I don't know what Liyan's mother said to her daughter, this girl can't help but blush when she sees Zhang Lan now.

Whenever this time, Zhang Lan couldn't help but feel a burst of pride: This wife seems to be unable to run. Think about how difficult it is for a man to find a wife in the future with the serious imbalance in the ratio of men and women in the country, and he has now occupied a happy man.

This kid obviously hasn't realized that as long as he wants, he probably won't have to do this for his wife in his life. Problems and worries.

It was at this time that the trend of history was once again deflected: the Kosovo war was over.
