Therefore, just as everyone rushed up to watch this beautiful and beautiful fighter, Qin Feng retreated out of the crowd, and then, he saw that General Lin was also squeezed out.

Of course, General Lin also pushed the boat along the river, if he hadn't taken the initiative to withdraw, others would not have squeezed it hard, the two stood on the periphery, looking at the entire airport, Qin Feng spoke: "The air base here is obviously much better than ours, they are all two-runway layouts." ”

For the air base, the benefits of the double runway are many, which can greatly increase the frequency of fighter sorties and recalls, and in wartime, it is easy to have the opportunity to take off, and if the main runway is bombed, then take off from the alternate runway.

Dual runways are the standard configuration of many countries, and when Qin Feng went to Pakistan before, he was also equipped with such a device, but it is not in China, most of the air bases in China only have one runway, of course, the reason is still money, the construction of double runways is obviously more expensive than a single runway.

There are too many air bases in China, because the existing fighters are short-legged and the range is not enough, and if you want to cover all your airspace, you have to build more bases.

If the Su-27 can be introduced, then there is no need, this kind of wide and long-range aircraft, once introduced into the country, a base, can control a large area of airspace, the surrounding airports can be abandoned, you know, the maintenance of the operation of the airport, the cost is also very high.

This is the significance of the long-range fighter, now, the army is reforming, constantly reducing the number of the army, improving the quality, the air force should also develop in this direction, the number of fighters operated by the air force will be reduced, but the performance of the fighter will have a qualitative improvement, it depends on the introduction of this time!

MiG-29, it's not what you need, at the right opportunity, you have to ask the other party to see the Su-27!

"Hey, my old friend, you can sit still." Shaposhnikov came up to him and said, "They're all watching, as if you're not interested." ”

I'm really not very interested, its short legs don't meet our needs, but General Lin didn't say it now.

"Let's go, let's go to the auditorium over there, and in half an hour, the air show will begin."

The Kubinka base is the main base of the Soviet Air Force, and the pilots here are very skilled in flying skills, so it is a very ordinary thing to perform an air show, and there is no need to make any arrangements in advance, just catch one of them.

When the expedition team was seated, the air show began, but when they heard the rumbling sound in the distance, everyone was very surprised, this sound was not a jet at all, but... That Il-2 attack aircraft!

The pilots who flew the planes, also dressed in the attire of that era, wore a leather flight cap on their heads, and without even closing the cockpit canopy, they slid past everyone's eyes.

For many, this is the first time, although for a pilot, the first flight started on a propeller plane, but it was a trainer plane, with a short nose in front and a piston engine or turboshaft engine that was not very powerful.

Now, the front of this kind of fighter, which occupies almost half the length of the fighter, is all engines, Qin Feng remembers reading in the book, and the later use is AM-38F liquid-cooled supercharged V-type 12-cylinder, 1720 horsepower.

On the engine of the fighter, there has been a dispute between liquid cooling and air cooling, and the liquid-cooled engine is now in this long shape, because the cylinders of the engine can be arranged next to each other from front to back, without considering the factor of heat dissipation, because there is coolant to dissipate heat, so the engine is also very stable and will not overheat.

The air-cooled engine is a star-shaped structure, it is placed on the outside in front of the nose along the shape of the circle, so that the length of the engine is very short, but the windward area is super large, it needs to deploy all the cylinders to the front, so as to meet the heat dissipation needs of the engine, so, in this way, it seems that the air-cooled engine is not easy to use, but it has a simple structure, in air combat, even if it is hit by a few bullets, it is blown up one or several cylinders, and it can continue to fly, but it is liquid-cooled, As soon as there is one shot, the engine is scrapped, and it often hits its cooling tank or something.

Liquid cooling and air cooling have been debated for a long time, but in the end, they have entered the ruins of history, and the emerging one is the jet engine, and the jet engine has also gone through a lot of technical route disputes, and now the most recent should be from turbojet to turbofan engine.

The research and development of the engine determines the success or failure of an aircraft, the Soviet Union has a lot of aero-engine design bureaus, constantly improving their design level, and their own side, but has been copying, up to now, the reliable and qualified power of the J-10, there is no ah.

Qin Feng sighed in his heart, and at the same time watched the take-off of this fighter, which was also the first time he had seen it with his own eyes.

The long nose will block the pilot's view, the pilot can only see the sky, judge whether he is yawing by virtue of the runways on both sides, the engine is emitting black smoke, the fighter plane slides in front of their eyes, even three hundred meters are useless, and the landing gear has already left the ground.

This is the benefit of the propeller era, with short take-off and landing distances, low take-off speeds, and flat fields that allow fighters to fly if there is no suitable runway.

Then, the flight show of the Il-2 began, as a propeller aircraft, it is impossible to climb at a large angle of attack after takeoff, its power is simply not enough to support such an action, otherwise, it will fall around its own axis, propeller aircraft era, the reaction moment of the propeller is very strong.

Its straight wing, in front of everyone's eyes, the advantage of this kind of wing, that is, the maneuverability is very flexible, look at now, after it takes off, it turns around a small radius in the sky, and it comes, just this basic action, it is enough to make the jet envious.

The turning radius is small, so it is also easy to play a game of peek-a-boo with jets, and it is by virtue of this advantage that a young man from West Germany can fly a small propeller plane all the way to the landing on Moscow's Red Square, which is also a famous event that caused a sensation all over the world, and even caused a strong shock in the entire Soviet Territorial Defense Force.

The wonderful performance of the Il-2 began with this small radius turn.
