In-flight refueling is a way to effectively extend the airplane's time in the air, and in the Western world, in-flight refueling is already commonplace, and it is a basic skill that pilots must master.

For example, during the Vietnam War, pilots often did not care about their fuel consumption, and when the fuel consumption was about the same, they would naturally go to the air tanker, refuel and continue to fight.

There was even an extremely special thing that happened to an air tanker of the Navy, which ran out of fuel while flying, and the fuel it carried for fighter jets was different from its own needs, so although it had oil in its stomach, it could not use it.

It called an Air Force tanker to refuel it, and while it was receiving fuel, a Navy fighter flew up to it and asked for refueling.

In this way, the three planes, connected in a string, the one behind received the fuel in the front, and did not leave until the refueling was completed.

Suffice it to say that in foreign countries, refueling in the air is all too common.

On the one hand, there are no suitable air tankers, and on the other hand, the country implements air defense in important areas, and an air base is only responsible for air defense operations in an area around itself, so it has no need for long-distance raids, almost take-off, interception, and return, and there is no need for air refueling.

When the Air Force developed to offensive air defense, air tankers were a necessity, and now they are working in this direction.

Although Qin Feng has not flown the air refueling mission, he still knows the basic principle, as long as he stretches the refueling probe on the plane into the conical sleeve in front of him.

Qin Feng worked hard, but things were obviously not as he imagined, getting closer, closer, closer and closer, and every time the probe of refueling approached the cone sleeve, the cone sleeve shook for a while, and then left.

At this time, Qin Feng noticed a key problem, that conical sleeve was active!

The wings of the tanker plane, the refueling pipe that stretches out, floats in the air, and the conical sleeve at the tail is also floating, and when the fighter approaches, the air flow of the fighter will also have an effect on this conical sleeve, and in this way, as soon as it gets closer, the conical sleeve is ejected away.

Damn, how exactly do people do that?

Qin Feng was very strange, and repeated it several times, and his palms were full of sweat, so he could only come down helplessly.

Now, not to mention the return home, even the normal performance of an in-flight refueling mission is like this, and after a while, if it lands on the aircraft carrier, it will be even more ugly.

Seeing Qin Feng's appearance, Colonel Mido smiled: "Qin, when flying in the air for refueling tasks, you must be fast, accurate, and ruthless!" ”

As he spoke, Colonel Mido sat down and demonstrated to Qin Feng, he was also slowly, slowly approaching, but when he was still a meter away from that probe, his movements sped up!

In Qin Feng's dazzle, he saw that the Super Flag fighter almost crashed into it.

Poke this chrysanthemum, it turned out to be fast, and before the airflow affected the cone sleeve to flutter open, the refueling probe had already reached in.

Qin Feng nodded, he didn't know, now this little experience, more than ten years later, actually used, when using the H-6 modified air tanker to refuel the J-8 in the air, many failures, are too careful, the last moment, must be bold!

Song Lao, Mr. Gu and others also sat down and took a test flight in turn, for them, the feeling was different from Qin Feng, they were from the designer's point of view.

"If it weren't for the simulator's problems, then its flight quality was somewhat poor, at least worse than our existing fighters." Song Lao came to this conclusion.

Qin Feng did not successfully complete the simulation mission, in addition to not being able to refuel in the air, another reason is that the flight quality of this simulator is indeed not good!

Aircraft designers, the first thing to look at is the flight quality, this simulator feels, the flight quality is very poor.

At the same time, if you have such a flight simulator in the future, as long as you input the flight control rate of the third-generation aircraft, then you can simulate it.

"The simulator must be realistic, otherwise, it may bring side effects." Mr. Gu also said on the side.

The simulator is to simulate the aircraft, if it can't be realistically simulated, so that the pilot thinks that the aircraft is like this, and some of the techniques cultivated are just inconsistent with the real flight, which will bring about the backlash.

Hearing everyone's discussions, Colonel Mido sighed in his heart, these experts, all of them are very powerful, and it can be seen at a glance that this system is actually deliberately increasing the difficulty, and when it is controlled, the gain is a little large.

In the afternoon, the visit was over, and we gained a lot, compared to the simple flight simulator in China, the technical level of the flight simulator here is still very high.

At the same time, the meaning of the French side is also very clear, if the Air Force chooses the Mirage 2000 fighter, then it must also choose some simulators, so that training pilots can effectively reduce the cost of training, in short, the French are in business, to sell more things to China, to earn more profits, is their biggest purpose.

Coming out of the simulator factory, it is already night, everyone is carefully exchanging experience, in short, the overall view is that foreign aviation technology, is indeed higher than the domestic one, even if it was an air show before, it was also a horse and a horse, and this time, it is really to see the gap, this gap, but in the stimulation of everyone, work hard, catch up with the world-class aviation technology.

At the same time, with the West opening its doors, it is also the fastest and most efficient way to introduce from the West.

Of course, because we don't know what the environment here is like and whether there is eavesdropping, we are very careful not to compare it with the projects that are being bid for in China.

The night passed, and the next day, test flights continued.

On this day's test flight, Qin Feng finally sat in the front cabin.

It can be said that the rear cabin has a camera and a monitor, so it is still possible to complete the basic flight subjects, but if you want to have a good field of vision, it is naturally the front cabin.

In a typical two-seater, the front compartment is for the pilot, and the rear compartment is reserved for the weapons operation officer.

Looking at the curved windshield in front of him, Qin Feng's heart was full of joy. This field of view is much wider than the previous three-piece windshield, and if you sit in the cockpit of the F-16, there is only one big bubble, nothing, which must be more spectacular.
