So, just as everyone rushed up and watched this beautiful fighter jet, Qin Feng retreated out of the crowd, and then he saw General Lin being squeezed out.

Of course, General Lin also followed the situation. If he hadn't withdrawn voluntarily, others would not have squeezed in. The two of them stood outside and looked at the entire airport. Qin Feng spoke: "The air force base here is obviously much better than ours. They are all in a double runway layout."

For air force bases, the benefits of dual runways are many, which can greatly increase the frequency of fighter jets dispatch and recycling. During wartime, it is easy to have the opportunity to take off. If the main runway is bombed, take off from the spare runway.

Double runways are standard in many countries. Qin Feng used to go to Pakistan, which was also equipped like this. However, it was not the case in China. Most domestic air force bases only have one runway. Of course, the reason is still the funds. The construction of double runways is obviously more expensive than a single runway.

There are too many air force bases in China because the existing fighter jets are short-legged and have insufficient range. If you want to cover all your airspace, you have to build more bases.

If Su27 can be introduced, there is no need. Once this wide long-range aircraft is introduced into China, a base can control a large area of ​​airspace, and the surrounding airports can be given up. You must know that maintaining the operation of the airport is also very expensive.

This is the significance of long-range fighter jets. Now, the army is reforming and constantly reducing the number of troops and improving quality. The Air Force also needs to develop in this regard. The number of fighter jets operated by the Air Force will be reduced, but the performance of fighter jets will be qualitatively improved, which depends on the introduction this time!

MiG 29 is not what you need. At the right opportunity, you must ask the other party to see Su 27!

"Hey, my old friend, you can really sit still." Shaposhnikov came over and said to him: "They are all watching, you don't seem to be interested."

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

"Let's go, let's go to the audience there. In half an hour, the flight will begin."

The Kubinka Base is the main base of the Soviet Air Force. The pilots here have superb flight skills, so it is very ordinary to conduct a flight performance. There is no need to make any arrangements in advance, just grab one of them.

After the brigade's inspection team sat down, the flight performance began. However, when everyone heard the rumbling sound in the distance, it was strange that the sound was not a jet at all, but... the Il-2 attack aircraft!

The pilots flying the plane were also wearing the outfits of that era, wearing a leather flying hat on their heads, and even the canopy cover was closed, and they just slid past everyone.

This is the first time for many people. Although for a pilot, the first flight started on a propeller plane, it was a trainer. The front nose was very short and it contained a piston engine with a low power or a turboshaft engine.

Now, the front of this fighter occupies almost half of the length of the fighter, and it is all engines. Qin Feng remembers that he read in his book that the later adopts am-38f, liquid-cooled mechanical supercharged V-type 12 cylinder, 1720 horsepower.

There has been a dispute over liquid cooling and air cooling on the engine of the fighter. The liquid cooling engine is in its long shape. Because the engine cylinders can be arranged from front to back, there is no need to consider the heat dissipation factor. Because there is coolant to dissipate heat, the engine is also very stable and will not overheat.

The air-cooled engine is a star-shaped structure. It is placed in front of the head and along the shape of the circle on the outside. This will result in the short length of the engine. However, the windward area is super large, and it needs to deploy all cylinders to the front to meet the engine's heat dissipation needs. Therefore, it seems that the air-cooled engine is not easy to use, but its structure is simple. In air combat, even if it gets a few bullets and is blown up by one or several cylinders, it can continue to fly. However, if it is liquid-cooled, as long as there is one, the engine will be scrapped and it will often hit its cooling water tank.

Liquid cooling and air cooling have been arguing for a long time, but in the end, they both entered the ruins of history. The newest one was the jet engine, and the jet engine also went through a lot of technical routes. Now, the most recent one should be from turbojet to turbofan engines.

The development of engines determines the success or failure of an aircraft. The Soviet Union has many aero engine design bureaus, constantly improving their design level, but its own side has been imitating it. Until now, the reliable and qualified power of the J-10 has not yet been there.

Qin Feng sighed in his heart, and at the same time, he watched the takeoff of this fighter jet. This was the first time he saw it with his own eyes.

The long nose blocks the pilot's view. The pilot can only see the sky. He judges whether he is yawing by the runways on both sides. The engine is blazing black smoke, and the fighter slid past their eyes, making it useless to even three hundred meters, and the landing gear has already left the ground.

This is the benefit of the propeller aircraft era. The take-off and landing distance is short and the take-off speed is low. If there is no suitable runway, the flat field can also allow the fighter to fly.

Then, the Il-2's flight performance began. As a propeller aircraft, it was impossible for it to climb a high angle of attack after taking off. Its power was not enough to support such actions. Otherwise, it would fall around its axis. In the era of propeller aircraft, the reaction torque of propellers was very strong.

Its straight wings are presented in front of everyone's eyes. The advantage of this wing is that its maneuverability is very flexible. Look at it now, after taking off, it turned around a small radius in the sky and came over. Just this basic action is enough to make the jet envious.

The turning radius is small, so it is easy to play hide-and-seek games with the jets. At that time, a young man from West Germany could fly a small propeller plane and land on the Red Square in Moscow. With this advantage, it was also a famous event that caused a sensation around the world, and even caused a strong shock to the entire Soviet National Air Defense Force.

Il-2's wonderful performance started with this small radius turn.
