"The biggest drawback of forward-swept wing aircraft is the structural strength of the wing, which has plagued many research organizations until now. When the current sweep-wing aircraft reaches www.biquge.info a certain speed, the outer wings will be twisted and deformed to both sides due to air resistance, and with the increase of the angle of attack of the wing, this bending divergence phenomenon will be further aggravated, gradually forming a malicious circle, when the speed reaches a certain critical point, it is easy to break the wing. The main solution to this problem is to increase the structural strength of the wing, and the existing material even if the titanium alloy with the highest strength, under the conditions of the average speed of the modern third-generation fighter, also needs to increase the volume and density of the structure, just as one chopstick originally supported the wing, and now two chopsticks are used, but this method increases the weight, which is undoubtedly a very obvious failure for the aircraft, so the advantages of the forward swept wing design are obvious, but the disadvantages are also obvious, at least under the current technical conditions, Although all countries are studying forward-swept wing technology, most of the practical applications are still in the field of civil aviation, because the speed of aircraft in the field of civil aviation is generally not high, and the existing materials are enough to support forward-swept wing aircraft wings to resist bending and divergence, and then obtain more advantages than swept wings. ”

Xu Dong stood in front and talked eloquently, and among the people below, except for some technical experts, non-technical personnel such as Li Mo and Deputy Commander Assad also understood seven or eight points.

"In materials science, especially in the field of alloy materials, Xingchen Group has mastered the world's most advanced technology and manufacturing process, and we have silicone oil alloys that are almost likely to become 'universal alloys', which have developed to more than a dozen types in two generations, which basically meet the needs of relevant research and production materials. The mechanics of our second-generation silicon-uranium-magnesium alloy materials are excellent, twice the strength of high-strength structural steel, 2.5 times that of super-hardness titanium alloys, and the density is only half of that of structural steel, and one-tenth smaller than that of super-hardness titanium alloys. What's more, we use nuclear-powered engines, and from our tests of engines during this time, the maximum thrust-to-weight ratio exceeds that of lift engines and ramjet engines, and is close to that of rocket engines used in spaceflight. This is only because our current equipment is not up to the mark, and we can't get accurate data in many aspects. ”

Li Mo's originally frowning brows relaxed, and from Xu Dong's words, he heard confidence, for these scientific researchers, with confidence, there would be no difficulties. Now it seems highly likely that the 'Space Fighter' program will be completed within his expectations.

"Since the advantages of forward-swept wing technology are so obvious, and we have overcome the shortcomings, does it mean that you are already planning to use forward-swept wing technology on the 'space fighter'?" Deputy Commander Assad also asked happily. He is the deputy commander of the Air Force, Li Mo usually does not manage the internal affairs of the Air Force, he is equivalent to the real person in charge of the Air Force, and the 'space fighter' is the key to the strength of the Somali Air Force, so Assad is very concerned about every detail of the development.

Hearing Assad's question, Xu Dong smiled slightly, "The use of the forward-swept wing design is only one of the two solutions we have come up with so far, and this plan is called the 'forward-swept wing solution' internally, and the next thing I want to show you is another plan - the flying wing solution." ”

As soon as Xu Dong's words fell, the electronic screen on the wall changed, and the original 'Su-47' fighter disappeared, and another type of aircraft appeared, and this time, without Assad opening his mouth, Li Mo knew who this shape borrowed.

"B-2 strategic bomber?" Li Mo said in surprise.

The plane on the electronic screen was like a miniature version of a B-2 strategic bomber, but after looking at it carefully, Li Mo still noticed some differences. First of all, both of them use a wing-body fusion flying wing structure, and the trailing edge of the wing is zigzag, but the difference is that the leading edge of the wing is not a straight line, but has a concave angle close to the fuselage, if you look down from above, it looks like a Su-27 fighter with the nose and tail cut off. Moreover, the wing sweep angle on this design is large, and the wing is not as long as that of the B-2 bomber.

"This is just a sketch, because this design is much more difficult than the first one." Xu Dong said with a serious face.

"The idea of the development team is that we are currently focusing on the 'forward-swept wing scheme' because we want to speed up the time. After the design of the forward-swept wing scheme is completed, we will further study the shape of the flying wing, because we all know that the aircraft shape design will become more and more simple with the development of technology, which is in line with the principle of aerodynamics, and in the future, maybe there will really be a flying saucer-shaped aircraft, and the flying wing shape can be regarded as a stage of the development direction of the aircraft, because it is compared with conventional aircraft, the tail wing is removed, which is a breakthrough in technological development, and maybe even the wing can be removed in the future. ”

At this time, Li Mo understood that the two plans that the 'space fighter' research and development team came up with, one was to come up with it in a hurry, and the design was also at the current technical level, and the characteristic was that the technology was relatively mature, safe and reliable. Although the flying wing aircraft has been discovered and applied a long time ago, it is not the mainstream in the current aviation industry and cannot become the mainstream, one is the wrong development direction, the second is the technical problem, and the third is not in line with the current needs. Therefore, the 'space fighter' research and development team regards the 'flying wing program' as a future development goal. Just as in the case of weapons development in many countries, there is a 'sustainable' development plan for equipping one generation, developing one generation and designing another.

"Xu Dong, when do you think the 'Forward Swept Wing' space fighter will be finalized and produced?" Li Mo finally asked one of the most important questions.

The plan was taken out, and the plan was formulated, but when it was completed was what Li Mo valued the most. Because there is always a sense of urgency and crisis in his heart now.

Since the intimidation of nuclear weapons is not really invincible, Li Mo is 100% enthusiastic about the development of conventional forces, and time has once again become the object of Li Mo's race.

Xu Dong hesitated for a moment before replying, "It's about the same before the second half of next year." He didn't have the confidence to say it himself.

And Li Mo is still not satisfied with this time, now to the second half of next year, there are still nine months, nine months of time to make an aircraft from paper to the real thing is too difficult, this is not a complete and mature design drawings, among which there is a more detailed verification of the aircraft, this process takes a lot of time.

"Well, then let's do it, to ensure the safety of the plane as much as possible, I don't want to fail to fly when the time comes." Li Mo nodded and acquiesced to this guarantee.

After leaving Baidoa Industrial Park, Li Mo returned to Mogadishu.

He did not go to the Ministry of Defense, but returned to his home in the family compound of the General Staff. In the two days since he returned from North Korea, he has not been back here.

In ancient times, there were three countries without entering, and Li Mo didn't know why he was so busy.

In the yard, his son Li Chen was chasing with his sister Jiang Yunyun, and the adult lion head was lazily lying in the shade of a tree to enjoy the shade, and when he saw Li Mo coming back, this guy just glanced at it.

Li Mo didn't bother the children, and went back to the house directly, only to find that his father Li Haojun and Li Yanran's father Li Zhendong were both at home.

Last year, these two people didn't know what they were thinking, so they transferred their studies to others, and then went together to complete a 'trip all over Africa', threatening to go to every country in Africa to understand the local customs and customs.

Li Mo didn't stop it, but instead sent a few people to protect them, including the former members of the wild wolf mercenaries, these people have been in Africa for a long time, and they are very familiar with many places. It's just that Li Mo knows that the two elders have only traveled to more than a dozen countries so far, and they have only traveled less than a third, so why are they coming back now?

"Dad, why are you back?" Li Mo sat on the sofa and asked suspiciously, he was either in North Korea or in the industrial park these days, and he didn't pay attention to the news of the second elder for a while.

The second elder looked much darker than before, it seems that in their trip to 'travel all over Africa', they are not just taking a plane and a car, otherwise they would not be so tanned, but Li Mo found that the two of them were full of spirit, especially Li Zhendong's father-in-law, who was in his fifties, and felt similar to Li Haojun, who was in his forties.

Li Zhendong glanced at Li Mo when he heard this, but he didn't reply, he just teased Li Ying'er in his arms, pinched his granddaughter's little hand and kept grimacing, making his granddaughter giggle and laugh. And Li Haojun was holding two dragon and phoenix grandchildren in his arms, and his mother Fang Yuxiang was staring dryly.

"If you don't leave, it's not peaceful to go out and have fun now." Li Haojun said thoughtlessly.

Li Mo frowned, he knew that something must have happened. And why didn't the people sent to protect report it?

"Now many places in Africa are very poor and chaotic, I only knew that Africa is chaotic before, but it is not clear what kind of chaos is this, this time I have traveled to many places, mainly those small towns and relatively remote places, and finally let me see what chaos is." Li Zhendong seemed to see his son-in-law's thoughts, and said casually.

"Do you know how to run around? At that time, I said that the two of you were going around a few big cities, and you had to drill into those remote places, and this time you were almost kidnapped by a local tribe. The mother-in-law on the side was a little angry.

Li Mo only knew what was going on, and he also felt very funny in his heart, these two elders really regarded themselves as adventurers and explorers, in Central Africa, many tribal societies are still extremely barbaric, and the root cause of African chaos is poverty, many people can't open the pot, so they have to take risks. Or because of political reasons, tribal conflicts, pro-opposition conflicts, etc.

"Since it's chaotic, I won't go, I think Dad, you can go to other places, such as some parts of Europe and America."

In the evening, Li Mo got the news from Wang Ning that the kidnapping of the second elder was just an accident, not for the surname, which made Li Mo breathe a sigh of relief, if someone targeted the second elder, it means that the situation is already very critical, and the other party needs to use this despicable act to deal with Li Mo.
