Zhang Lan nodded, indeed. In the case of an air tanker, all problems are solved, and the two huge wings that can store up to 50 tons of fuel will become an additional fuel storage tank in addition to the main fuel storage tank...... In terms of the weight of fuel carried into the air alone, the amount of fuel carried by the An-124 air tanker powered by this nuclear fission fuel cell will definitely make Americans feel ashamed!

But if it is used as an ordinary transport aircraft, then the problem is quite serious, what can be stuffed into this fuel tank? It doesn't seem to be the case that you can't find anything like that.

It's a pity that such a large space is wasted, but how to use it? This question was not originally a problem, but it saddened Xiao Chenxi and his group.

"This, I don't want to think about it for the time being," Zhang Lan, who didn't figure out what to do after thinking about it for a long time, only shook her head helplessly in the end, "Thinking about it slowly, the answer to the question is not something that can be figured out in a day or two." By the way, the results of computer simulations, which is higher in the efficiency of using the propeller fan or the original turbofan engine? ”

"Basically, it's about the same, but relatively speaking, it's still more efficient for the rotary propeller fan engine, and the original D-18T turbofan engine is a super-large bypass ratio without afterburner turbofan engine, which can only do subsonic flight." For this point, Xiao Chenxi is quite complacent, "After we have re-corrected the blade surface, production materials and inclination angle and shape of the counter-propeller fan, the efficiency of the new counter-propeller fan is now higher than the efficiency of the counter-rotor fan we used on the tiltrotor before, and the result of our simulation is that the cruising flight speed at an altitude of 12,000 meters can reach 950 kilometers per hour, which is already very close to the speed of sound." ”

(It has been proven that the efficiency of the propeller fan engine is higher than that of the turbofan engine, and the efficiency of the D-27 propeller fan engine used on the An-70 transport aircraft is 15 percent higher than that of the Il-76 transport aircraft using the PS-90A-76 turbofan engine.) ）

The blade surface of each pair of propeller fans is quite similar to the shape of the optimized wing when flying at supersonic speed, and the design of the large inclination angle and large sweep angle also ensures the best starting efficiency and the quietness of the rotation speed at the tip of the rotary propeller fan when it is about to reach the speed of sound.

"At this speed?" Zhang Lan frowned, this speed was a bit unexpected, "The An-124 was designed according to high subsonic speed at the beginning of the design, and the cruising speed was only 850 kilometers per hour, but now at 950 kilometers, will the wingtip part of the wing produce shock waves or vortices?" Does this flight speed have any effect on the strength of the fuselage? ”

"It's fine, it has a bit of an impact on the wing, but adding a small vertical tail that flips up 85 degrees on the wingtip can improve the vortex at the wingtip. As for the strength aspect of the wing, there are no problems at all. Xiao Chenxi gave Zhang Lan an affirmative answer.

"Then there's no problem, but what should be done about this part of the space inside the wing so that it doesn't go to waste......" Zhang Lan responded, nodding and muttering.

I never forget the question of how to make effective use of every inch of space on board.

――――――――――――――――

Time obviously won't slow down because of Zhang Lan's muttering, when Zhang Lan was still immersed in her own mess of things, Xiao Chenxi brought Zhang Lan a good news.

"The location of the guy who gave us trouble, we determined." Xiao Chenxi's tone was calm.

"Really?" Just now I followed Zhang Lan, who didn't know what to mutter. Suddenly, a spirit of excitement even became a lot more energetic, "Are you sure of the specific location of this guy?" ”。 …,

"That's right, just figured out where he's now. Now he is in an ancient castle on a hill in Sweden. But we haven't decided who this guy really is, so let's say, what are you going to do? ”

What to do? What to do? There is no doubt that according to Zhang Lan's temperament, since someone dares to take the initiative to provoke the door, there is naturally no reason not to clean up this guy, but this is not the most important thing, Zhang Lan needs to determine who this guy is. After knowing that this technology belongs to the Alice Group, this guy dares to stretch out his hand casually, Ya is not simply bold to be able to describe, if this Ya doesn't feel that the strength of the forces behind him is so strong that even the Alice Group can't afford to provoke it, this guy will definitely not make a move.

"Drop two bombs?" Zhang Lan instinctively came up with such a sentence, for this guy who has made trouble for himself several times, Zhang Lan instinctively has no good impression of this girl, if he can directly blow up Ya, then it is better to blow up Ya directly.

"......" The black line on the face of the two girls' heads!

Dropping two bombs on the territory of a sovereign country, although this is not a big problem, and it is guaranteed that it will not be discovered by Sweden, but it is ...... The two girls felt that they couldn't afford to lose this person. When do we want to clean up and sneak attack?

"Hehe......" Zhang Lan, who had just said the words, also felt that her instinctive reaction was too intense, touched her head slightly embarrassed, and laughed twice, "In this way, first make sure that this guy is here or if we are listening to his equipment, such as a phone or something like that, and then we'll talk about it after it's confirmed, OK?" ”

“OK。” The proposal was pretty much the same, and the two girls nodded together.

But...... How can you kill this guy?

Zhang Lan involuntarily had such a thought in her heart again, which fully proved how dark this guy is.

But obviously, Zhang Lan obviously doesn't think so in his heart, in this kid's opinion, this guy has too much trouble to take pictures of himself, and he dares to make trouble for himself again and again, although these so-called "troubles" can't pose a real threat to himself, but Zhang Lan still feels quite unhappy!

Whoever is it is to murder this guy again and again will not be very happy in his heart. Yes, Young Master Ben is fine, but this is Young Master's ability to save his life, otherwise his life would have been lost. The guy is obviously not a good thing, and it is estimated that he is also extremely unsightly, otherwise how could he attack himself so arrogantly, and more than once?

Since he doesn't even care about Alice's name, it means that he thinks he has two brushes in his hands, and he thinks that he can be safe and sound under Alice's revenge, or that Alice doesn't dare to take him.

This kind of luck psychology is absolutely unacceptable! Zhang Lan said in her heart with an old-fashioned face.

"It's confirmed, I scanned it with the infrared thermal imaging system just now, and there is no infrared thermal reaction where the signal appeared just now, so it should be that the target is not there." Xiao Chenxi had some regrets. Frustrated, he scratched his hair.

"Huh?" Zhang Lan was stunned for a moment, "Is there any thermal insulation material used in the place where this guy lives to isolate the thermal energy reaction?" ”

"Impossible!" Xiao Chenxi didn't think about it, and directly refuted Zhang Lan's words, "With our current detection methods, this ancient castle has no possibility of isolating the thermal energy reaction. ”

That's right...... Zhang Lan was a little stupid and muttered, "This kid has a big life!" ”

――――――――――――――――

The sudden disappearance of "Asian Bermuda" has once again become the focus of international attention in recent days, and countless so-called "bricks" and "beasts" have jumped out and used their own so-called theories to prove that this situation is only a kind of activity that we cannot determine for the time being in the submarine plate in this sea area in the recent period, and now the activity of the plate has entered a stable period, so the "Asian Bermuda" has naturally disappeared, and the so-called "Asian Bermuda" has disappeared before. There is no theoretical basis at all, but some irresponsible media outlets have fabricated sensational news at will based on their own imagination for their own interests, newspaper sales, and eyeballs. …,

Naturally, the media refused to slap themselves in the face, so a war of words broke out again.

While the media are engaged in a war of words with the so-called experts. Governments and militaries, on the other hand, are not so optimistic: quite simply, they do not believe that this so-called "Asian Bermuda" is really the result of an unknown unstable activity on the earth's tectonic plates, as these so-called experts and professors claim, and when this activity tends to stabilize, the corresponding phenomena will naturally disappear - the so-called "Asian Bermuda" activity that has ceased to appear is the best proof of this.

On the basis of the evidence available during this period of time, they are more inclined to believe that this abnormal phenomenon in this sea area should be a phenomenon of some kind of artificial control, just as the United States now has a so-called "global environment" weapon, a weapon that can control changes in the natural environment of a specific area of the earth within a certain range, and perhaps this newly emerged Asian Bermuda is a weapon developed by a certain country.

Anyway, everyone knows, the so-called experts. It's a bunch of people who help people say good things after taking people's money, and the aura of education on their heads looks good, but they often make some common-sense mistakes when they speak, and they don't have any principles and positions if they are rich, and they are damned like the simplest paramecium.

If that's the case, that's too bad! No country wants to see such a scenario, and naturally, the Americans don't want to!

But what makes these countries feel even more chilling behind their backs is that so far, everyone has not discovered at all who this "mastermind" is sacred! However, vaguely, everyone believes that this mastermind behind the scenes may have something to do with a series of abnormal things that have occurred in their own countries during this period of time, and perhaps the time of the terrorist attacks that are causing chaos in various countries and the extremely rampant underworld activities are planned by these people behind them.

If that were the case, this damned one should be cast into the Endless Hellfire, where he will be burned daily by hellfire for a thousand years before he can be cleansed from his boundless sins...... But right away, these fellows smacked themselves in the mouth: even a thousand years of burning would not wash away even a ten-thousandth of his sins!

Because, this damn fellow, has caused trouble for himself again!

――――――――――――――――――

Lao Maozi was obviously very annoyed for a while, because this time the Chechen "rebels" obviously learned the experience of the previous two Chechen wars, and no longer resisted the Russian government troops who came to "encircle and suppress" them.

In a trance, the Russian military and government vaguely had an unusually familiar feeling, when a certain researcher of the history of World War II who was interested in the history of World War II and at the same time interested in the country to his south suddenly discovered that the current Chechen rebels are not using the sixteen-character proverb used by the neighbor in the south of him during World War II: "The enemy advances and I retreat, the enemy is stationed and disturbs me, the enemy is tired and I fight, and the enemy retreats and I chase"!

For a time, "the essence of guerrilla tactics in World War II was revitalized!" Such statements are becoming louder and louder in the world's military!

If this is not the most depressing thing for the Lao Maozi government and military, then the fact that the weapons of these damn Chechen rebels seem to be much more advanced makes Lao Maozi feel annoyed and begin to be suspicious: Damn Chechen rebels are a gang of robbers and robbers, can you expect a gang of robbers and robbers to develop their own weapons? It's a bit of a joke. But since that's the case. What the hell did these weapons in their hands come from, although they look the same as before, but the accuracy has improved a lot? …,

"Mr. Patrushev, will you Federal NSA find out what is going on?". Strongman Putin pointed to a 7.62mm Dragonov SVD sniper rifle on his desk, and pointed to the head of the National Security Service of the Russian Federation and his absolute confidant: Patrushev. Nikolai. Bora Danovic asked.

The strongman's eyes were quite unhappy when he looked at the Dragonov sniper rifles that could be found everywhere in the Erosian troops! Of course, you have a reason to be upset!

Although this sniper rifle is even considered by many people to be a sniper rifle that cannot be called a sniper rifle in the strict sense, and cannot be compared with the mainstream sniper rifles in Europe and the United States in many aspects such as shooting accuracy, range, power and multi-purpose, it is undeniable that this sniper rifle that was officially equipped with the former Soviet Army in 1967 is a squad tactical extension precision shooting weapon with excellent range and accuracy.

The Dragonov sniper rifle was captured from the Chechen war two days ago, which is not surprising, after all, Chechnya was originally part of the former Soviet Union during the Soviet era, and it is not surprising that the Chechen rebels have this sniper rifle in their hands. What really surprised and outraged strongman Putin was some performance data on this gun in a test report sent with this sniper rifle!

The test report said that because of the high record of this sniper rifle killing 23 Russian soldiers in the battle, it aroused the curiosity of Russian sniper talented soldiers, and they fought with this captured sniper rifle that was considered to be good luck, and in use, the soldiers were surprised to find that although the captured Dragonov SVD sniper rifle looked the same as the same sniper rifle equipped in the Russian army, but whether it was range and power, or dispersion and accuracy, All are far more than the sniper rifles equipped in the Russian army!

After sending the gun to the higher authorities for testing as quickly as possible, the relevant departments quickly came up with the data they wanted, and finally gave an explanation: the barrel of this gun is made of some alloy metal that Russia does not have at the moment, and the main material is pinched chromium alloy steel, which also has a certain titanium component. In addition to the barrel, the machining accuracy of this gun is significantly much higher than that of the existing Russian military industry.

It is the ultra-high machining accuracy of this gun that is the real reason why the accuracy of this gun far exceeds that of the same sniper rifle in service with the Russian army.

The sniper rifle used by the Russian government army itself is not as accurate as the same sniper rifle used by the Chechen rebels? If this isn't a joke, what does that mean? This shows that there is a country with a strong military processing industry that silently supports the rebels in Chechnya behind their backs!

This is nothing, before starting this war, when the Russian military and government were discussing related operational issues, they had already guessed that the reason why the Chechen rebels dared to start a new war must be supported by someone behind them - it was the United States before, and I don't know who it was this time.

Originally, everyone didn't pay much attention, and it seems that there is no one else to be found except for the Americans. But now it seems that things are not at all what they look like.

Who is that guy hiding behind him, and what the hell is he trying to do? This is the problem that strongman Putin really cares about, and it is also the reason for his anger, because before this, the Federal National Security Service, which is an intelligence organization, did not provide him with even a word of relevant information!

At the same time, Patrushev also understood that this was what really made the boss disappointed in himself: originally, such a thing was originally within the scope of his work, but if it wasn't for the sniper rifle that was accidentally captured, he wouldn't have known that there was a serious mistake in his work!

Patrushev's face is hot, this is clearly a slap in the face to himself! Naked, naked, slap in the face! Patrushev's face flushed with extreme shame and insecurity, and he wanted to drip blood!

A sense of extreme shame in his heart kept tearing and entanglement Patrushev, for the soldiers who value honor more than life, there is nothing more angry and ashamed for them than this shame, and this shame can only be washed away with the blood of the enemy!

"Mr. President, please rest assured, we will definitely find out about this matter in the shortest possible time!" "Smack!" , The back heels slammed together, Patrushev gave a standard military salute to the strongman Putin, and shouted loudly! ……，
