What does this mean?

When using a hard tube for refueling, the refueling machine does not have to do anything, just wait in the back, and this series of refueling activities are all operated by air tankers.

The U.S. Air Force is very enjoyable, the back of their plane, there is a king-shaped logo line, that is, the sign of the air refueling port, when the opening is opened, it seems to be beckoning to this telescopic tube, come on, come on me!

It is enough for them to keep a smooth flight, and what about the way the hose is? It is precisely because of various problems that in the United States, there is discrimination between the branches of the military, and the Navy looks down on the Air Force that are a group of guys who fly steadily, and in the eyes of the Navy, they are the real flyers, what is the Air Force?

Only Qin Feng knows that this simple air refueling is also the experience of the strength of a great power, the hose used by the US Navy is because it needs to take care of the refueling needs on the aircraft carrier, and the air tankers on the aircraft carrier are all very small, while the US Air Force uses this kind of big guy because it is a land airport.

Other countries, don't you know that it's good to refuel hard pipes? Is it because there is no such technology, but what about China? Even the hose refueling technology has not yet been overcome.

There are a lot of gaps, and we need to work hard to catch up.

Just in Qin Feng's thoughts, the huge Galaxy transport plane flew forward, gradually approaching the air tanker in front, at this time, if you can look at it from the outside, you can find a huge gap between the two, in front of the Galaxy transport plane, the air tanker is just a small person!

It's not an eagle in the sky anymore, it's just a giant whale in the sky!

Now, this whale is going to feed.

The telescopic rod of the tanker in front of it had already begun to move, slowly, slowly, and then suddenly stretched out and steadily stuffed into the nose of the C-5 transport aircraft, and its air refueling pipe was not on the back, otherwise the tanker would not have reached it at all.

Now, the two planes are flying forward together in the sky as a whole, and at the same time, aviation fuel is flowing through this pipeline, bubbling into the fuel tanks of the Galaxy Transport Plane, and it can fill in 800 gallons of fuel every minute!

If it is a fighter, a few minutes of docking at most is enough, but now the time is slowly passing, and when it is docked for ten minutes, it continues to refuel!

If it is hose refueling, it will be difficult.

As refueling progresses, the mass of the air tanker decreases and the speed increases, while the mass of the tanker increases, the speed decreases, the two sides pull apart, the hose tightens, or even breaks.

But the hard pipe will not, because it is retractable, in addition to telescoping at the time of docking, in the process of refueling in the air, it can also be telescopic to constantly adapt to the change of distance between the two sides.

Finally, the tube of the air tanker was withdrawn, and just when Qin Feng sighed that the refueling process was long, he opened his mouth wide again, and above his head, the second air tanker flew over!

Because this is a transport plane, there is no porthole in the back, so it is impossible for Qin Feng to see the situation around him, he doesn't know, there are actually two air tankers!

The first one had already been recharged, and the second one came over and continued to work in the same way, starting the long air refueling.

How does this work?

One must not be enough.

If it is an ordinary aircraft, even a B-52 bomber, it only needs an air tanker, but the C-5 Galaxy is different, you know, it can carry 150 tons of fuel at a time.

And a KC135 can transport 90 tons of fuel, but this is all the fuel, and it has to use it itself, so that it can be exported to the outside world, that is, 60 or 70 tons.

Two KC135s are enough to refuel such a transport aircraft, in order to transport their own two Jian-8 over, just this time, how much will it cost, fortunately, the Americans are quite interesting, this is included in the cost of the contract.

Of course, it is also conceivable that the Americans must have been looking forward to these two aircraft for a long time, because they are also interested in this kind of aircraft, this is a fighter independently developed in China, what is the performance of this fighter? Going to the United States, everything will definitely be declassified, and there will also be American test pilots to test fly this aircraft.

Qin Feng did not participate in the negotiations at that time, although he also felt that there was something wrong with it, but now that an agreement has been reached, it is not Qin Feng's turn to speak.

When the second air tanker completed the refueling mission and flew away, the transport plane also entered the normal flight route again, and the blue sea was below, and the sky was slowly darkening.

When he was about to arrive in the continental United States, the second air refueling began, and what made Qin Feng even more unbelievable was that this second time was refueling in the air at night.

The U.S. Air Force is operating around the clock, which is not lying, just look at the current style of people, but it is also because of the advanced equipment, the sign on the top is quite clear, in the dark, the telescopic sleeve in the air flashes fluoresce, and it is firmly put on.

After the second in-flight refueling, after a few more hours of flying, they finally arrived at their destination, the Grumman factory.

In the cabin, many people were asleep, and Qin Feng gradually understood that the relaxation of those crew members was not irresponsible, in the long flight, if they had been nervous, they would have been exhausted, and now, after performing such a long-distance transportation mission, they still have physical strength.

It also has something to do with the comfortable environment here.

This is the second time I have come to Grumman, I think the first time I came, Qin Feng also flew the MiG-21 and teased the other party's Tomcat fighter, and the scene at that time seems to be vivid.

By the way, Tu Lao should be here too! Qin Feng couldn't wait to see Old Tu.

However, it was still dark at night, and the Grumman personnel took them to the hotel next to them, and it was not until after dawn that someone came to greet them.

"Mr. Pelehak, it's a pleasure to meet you." When he saw this familiar person again, Qin Feng also sighed a lot, this can be regarded as a kind of fate, and then, Qin Feng saw that in the back, Tu Lao and the others also came over.

When he saw Tu Lao, Qin Feng really wanted to go over and give him a hug, and he also wanted to ask how the Jianqi CP project had progressed so far?

But this is clearly not the place to speak, or rather, not to whisper.

"Let's go, let's go over and take a look at the J-8 first, it has entered our workshop, and we can't wait." Pellehaq waved his hand.
