The Boeing 707 air tanker is actually the US Air Force KC-135 large air tanker, which is a large air tanker improved from the US C-135 military transport aircraft. The wingspan is 39.88 meters, the length is 41.53 meters, the height is 12.7 meters, the maximum cruising speed at 9000 meters is 982 kilometers per hour, the ceiling is 15240 kilometers, and the range is 5552 kilometers.

The reason why this large air tanker has become the wet nurse of the US Air Force is not only because it can refuel four fighters at the same time, but also because it has a maximum fuel capacity of 90 tons, and the maximum take-off weight of the entire aircraft has reached 146 tons! The telescopic casing air refueling system is adopted, and the adjustment distance of refueling operation is 5.8 meters, and the four fighters are refueled in the space range of 54 degrees up and down and 30 degrees horizontally!

This is the world's longest-serving military air tanker.

Being able to fool Iran into flying such an air tanker that the Republic has never been able to get to China was something Liu Yijiu himself did not expect at first.

And seeing that he had completely landed on the runway of Taipingsi Airport in front of him, Liu Yijiu himself was a little excited.

This thing is much stronger than the Sixth Master of the Republic, who has carried the banner for more than half a century.

The refueling aircraft developed by the Republic on the basis of the H-6, named H-6, has a maximum take-off weight of 75.8 tons and a maximum fuel load of 37 tons, while only 18.5 tons can be used to transport fuel to fighters......

Such a wet nurse is simply short of milk, and the child can't eat enough, so naturally she can't run far. Even if it has been improved countless times later. There is no way to solve these birth defects, the whole plane is too small.

Only two fighters can be refueled at a time. And it will be able to refuel up to six J-8 fighters.

When the air force of the republic used tankers, the typical formation was two six grandmothers with twelve eight masters. Then the 12 Eight Masters were divided into three four-plane formations, and three air cordons were set up within 1,200 kilometers to protect the nurses from being destroyed by the enemy.

You must know that the nurses of fighter jets are basically non-attackable, and they are still filled with aviation fuel, and if they are attacked, they will easily become a pile of garbage and fall down.

Without the nurse, the eighth master's combat radius is only more than 700 kilometers......

Of course. With a wet nurse, it is only an expansion of 1,200 kilometers, adding some time in the air.

Originally, Liu Yijiu didn't think of this problem at all, after all, the problem of air tankers was not within the scope of his consideration, in their time, because of the large-scale use of graphene, the mass of fighters was reduced, and the combustion efficiency of new aero engines reached a level that made this era impossible to look up to. That voyage can even circle the earth......

So, he did not take into account the problem of air tankers.

Moreover, there is simply no domestic platform suitable for changing into an air tanker.

The sixth master has carried the banner for more than half a century. In the end, it was because of this nurse's lack of milk that the Republic desperately increased the range of its fighters, and finally it was possible to cut out this formation. It is enough for the fighter to refuel directly at the airport, and it is not a problem to run around the world. Or maybe it's also with Yun Ten who fell behind after the success. Twenty dismounts have a lot to do with it.

All the time, large planes. It was not until the end of the fifties of the 21st century that the aviation technology of the Republic made a breakthrough - the emergence of super aerospace fighters!

It was only in 1997 that the first air refueling regiment of the Republic was formed......

For the Chinese Air Force, the combat radius of the fighter is small, and the air nurse is not powerful, and there is too little milk, which is a huge sadness.

Liu Yijiu came to this era, and he had no way to let the aerospace fighter appear when this kind of various foundations had just begun to start, even if he knew it completely. So, he tried to make the republic's air force stronger.

Only with a strong air force can air supremacy be guaranteed.

Moreover, it is further related to the supremacy of the sea and the guarantee of the security of the motherland!

"Wow, this plane is so big......" Li Rui had never seen such a big plane.

Even the pictures are rarely seen, the sixth master of the republic is already very huge for her, but she didn't expect that there would be a bigger plane than the sixth master!

"yes, this plane, it's too big. If we can understand the technology thoroughly and then transform the Jian-8, we can completely protect all our territorial waters and airspace......" Even Sun Daoqian, a person who specializes in transport planes and bombers, has to sigh at the huge size of this aircraft when he sees the real thing!

With a height of more than ten meters, it is too small for a person to stand in front!

Liu Yijiu didn't think this thing was too big. The space planes that the Republic later used to launch spaceships when it was building a lunar base would scare them to death if they were here!

Not to mention anything else, even the An-225, which will appear in the eighties, is far more than these aircraft!

I hope that because of his arrival, Lao Maozi will produce a few more of these huge planes that have not been surpassed before the forties of the twentieth century, steal them back, install nuclear power, and completely become a mobile fortress in the air, if it is full of bombs......

It was eighteen meters tall, the height of a six-story building! It is twice as long as the KC-135 in front of you, which is slowing down and stopping, and the wingspan is also twice as long!

For Liu Yijiu, the kind of air tanker in front of him that is about to be eliminated by the US Air Force, or it cannot be said to be eliminated, is just that the US imperialists have a KC-10 with more milk.

This thing is just right for the double and three index fighters they are currently designing.

A small plane like the eighth master can only go to the sixth master to feed them. Of course, if this nurse comes out, she can completely let a master with a large group of more than 20 planes play in the air. When the time comes, half of it will be enough to go out and beat people, and half of it will be enough to keep it for protection......

"We've got to make this plane ourselves!" Xia Fei's eyes were hot when he saw this behemoth.

As the commander of a country's air force, it is a huge shame that his own aircraft can only operate within the combat radius, and even the most basic airspace cannot be completely defended! There is no air base in the South China Sea, and the distance from the South China Sea Island to the most remote part of the Xisha Islands is even more than 1,000 kilometers!

"Yes, it must be done, Xiao Liu did a good job this time!" Long Yaohua looked at the huge plane that had completely come to a standstill, looked up, and muttered.

"If we have this in logistics, we don't have to worry about our air force being too small to fully patrol our sea areas because the combat radius is too small!" Li Yunlong gritted his teeth and said, then turned his head and said to Sun Daoqian, who was looking at the behemoth in front of him with an affectionate face: "Little Sun, give me a word, when can it be imitated!" From the base of the six to change the tanker, there is no need to do it, let's start with this! ”

Sun Daoqian didn't expect that when he had just seen this plane and hadn't even figured out how much technology it was in it that they couldn't grasp, Li Yunlong began to ask him when he would be able to copy it.

What is Qin Fei's situation, he knows better than anyone else, the technology of the bass engine has been introduced for a long time, and Qin Fei has not digested it until now.

J-8 II, until now, it has not used the Chinese heart!

"We can be responsible for the avionics system, and we can also take responsibility for the engine......" This time, Liu Yijiu did not shirk.

Anyway, they have been studying the avionics system of the fighter for a long time.

Take down the hardest part, and only they have the strength to take it!

Qin Fei should have nothing to say.

Moreover, Liu Yijiu also won the two most profitable parts. Aircraft engine is related to whether the aircraft can fly in the sky and various data when flying, and it is also related to the various performance of the aircraft.

It's the heart!

The highest profit means the highest technical content and the most technical difficulty.

"In six years, we should be able to supply engines for large transport aircraft! If our turbofan 10 project achieves a breakthrough, it may not be that long! ”

"Six years! Chief, please give us six years, as long as Director Liu can provide us with avionics system and power system, we will definitely be able to build such an aircraft ourselves! Sun Daoqian gritted his teeth and said.

The technical content of the F14 can even be said to be higher than the huge aircraft in front of you!

Liu Yijiu dared to guarantee that he could copy the American heavy fighter F14 in five years, why did he not dare to guarantee that the most core technology would be the imitation project undertaken by the Ninth Academy?

"Okay, I'll give you six years, the major aircraft factories, the personnel will be deployed by you, and the funds will meet your ...... to the greatest extent," Li Yunlong also said arrogantly.

When Liu Yijiu heard this, he immediately became anxious, he couldn't lift a stone and hit his own feet!

The project team of Yunshi must not let go.

Moreover, he also wants to dig people in other airplanes.

Qin Fei is engaged in transport aircraft and bombers, and his first choice is the Yun-10 team, which has completely stopped from the project research. Liu Yijiu has already told Ma Fengshan and Ma Lao that they should not run for funds, and the Ninth Academy will fully accept the large aircraft project and their entire team, no one is missing, just let them pack up their things and wait with peace of mind.

When the time comes, just give them a part of the territory directly in 611.

The current Rongcheng is not as crowded as it was decades later.

"Chief, this can't work, I still need people, they have all taken people away, how can I do it? Otherwise, I'd better keep it in my own hands! Objections were immediately raised. (To be continued.) )

PS: The eighth update, more than an hour late, is finally updated. This is already the limit, and it is not easy to wait for the daughter-in-law to change the baby's diapers......

Continue to go crazy tomorrow, possibly, still seven watches!
