F4 has huge hidden dangers

This shocked a few people.

"This is true, is it possible that even if it is imitated, our air force will not be able to equip it," the old man was also moved.

Seeing that China can have the most advanced fighters in the world, although the performance may be a little worse, but there are definitely not too many, as long as such fighters are equipped with dozens of fighters, they can greatly improve the national defense and security of the republic, especially on the northern border.

On the battlefield in Iran, the F4 fighter is quite good, although it has also lost a lot.

"The equipment is okay, but it's still far from what we imagined. Because this fighter is not able to perform super maneuvering at too high speeds, in the war, it is likely that the fighter will disintegrate because the fighter is super maneuvering when dodging faster missiles. When maneuvering at high speed, the huge overload will cause some systems inside the fighter to malfunction," Liu Yijiu immediately explained.

The strength structure of the F4 fighter has problems, and even if the joints are thickened at the root of the wings and the fuselage, there is no way to solve these problems.

This is due to the design aspect of the aerodynamic layout.

"Isn't that test pilot still awake" Long Yaohua asked with a frown, if this is the case, things will really be a bit troublesome.

The Air Force must have a more advanced fighter for the current national defense needs.

"Sober. He also reported the situation he encountered on the fighter, during the operation, there was no alarm at the beginning, and when doing the Super Cobra maneuver, the rotation of the fighter made the joystick a little inflexible. According to the introduction of Iran's combat heroes, most of the F4 fighters lost by Iran were caused by the failure of the fighters themselves, rather than being shot down by the French F" Liu Yijiu and others have investigated clearly.

Since the end of the test flight, he has focused on the analysis of these aspects.

Fortunately, test pilot Yin Qingyuan recovered quickly, and his body was not damaged too much. The only thing is that the overload force is too great.

"If our air force is to be equipped with advanced fighters, it must have better performance, after all, our military spending is not enough to support us with too much equipment. And fighter pilots will not give up their fighters in order to save their lives when they really encounter a breakdown. This makes it necessary to provide them with more reliable fighters, and in order to deal with more enemies, they must have higher mobility, such as the Cobra maneuver, which is very useful when dodging missiles and locking on enemies pursuing from behind; Super Cobra maneuveres, which is not only able to dodge. It can also avoid the enemy behind and go around behind the enemy's fighter planes from the disadvantaged position of being chased in the air during the chase battle," Liu Yijiu explained the role of these fighters' maneuver tactical movements.

The Air Force of the Republic actually has higher performance requirements for fighters.

Because the republic could not be equipped with advanced fighters in the same large quantities as the United States and the Soviet Union.

The United States can equip a large number of advanced fighters because the United States has a huge economic base and the national fiscal deficit has reached trillions of dollars; The USSR was able to equip not because they had a good economic base, but because the Soviets had always been costless in this regard, and they needed to have more equipment than the United States or even the entire NATO alliance combined.

During World War II, when Germany attacked the Soviet Union, the advanced Tiger tanks were overwhelmed by the torrent of Soviet junk T34 tanks.

In particular, the coming to power of Soviet Defense Minister Ustinov. His requirements were that the weapon be easy to manufacture and be able to quickly equip the troops on a large scale

Not good for China, not good for the economy, not good for the industrial base.

"At present, on the northern border, the cross-border reconnaissance of Soviet fighters is becoming more and more powerful, and the J-7 and J-8 cannot catch up with the MiG-25 at all"

"I know this very well, even if the J-8 II is equipped with pulse Doppler radar, it cannot be compared with the Soviet Union's MiG-29 and the Su-27 that has been equipped with troops, no matter how it should enter, the J-II will not be able to step into the range of third-generation fighters" Liu Yijiu sighed.

The J-7 was originally an imitation of the MiG-2. The J-8 is also developed on the basis of the J-7.

The USSR developed the MiG-23, MiG-23 on the basis of the MiG-25, and now the MiG-29 has also come out.

With each new model, there is a great improvement.

If only performance is said. Compared with the Soviet-style MiG family, the J-7 and J-8 are much worse than the MiG-25, and it is even more impossible to achieve the high-altitude and high-speed performance of the MiG-25.

"But the structure of the F4, especially the connection between the wings and the fuselage, the fuselage skin, etc. They can't withstand too much overload, and the internal hydraulic system will have problems when maneuvering at high speeds, and the fly-by-wire system will also have problems."

F4 was researched by the Americans, and they produced it.

But the best players with the F4 fighter are the Iranians, who have participated in too many actual battles in the F4; And the one who knows F4 best has become Chinese, and Americans will never have such a crazy person as Liu Yijiu, who let the pilot do all kinds of dangerous actions during the test, and finally accidentally discovered such a problem.

"What if these problems are improved," the old man asked with a frown.

"The improvement work is actually already underway, and the Giant Panda Project is a modification of the F4." Liu Yijiu introduced the situation of the giant panda project.

The Giant Panda project completely combines the advantages of the Su-27 and F4, and the aerodynamic layout completely surpasses the F4, and the performance is much stronger than the Su-27. The performance of the turbofan, compared with the engine AL3 used by the Su-27, may as well be more.

The only thing that is almost the avionics system and the radar system is the same.

This is where mobility comes in.

"Although it is said that the manufacture of a new prototype has begun, it will take time for the first flight to be tested on the ground, and the wind tunnel." Long Yaohua said with a frown. "Those people won't give you much time."

For many people, the introduction from abroad will be able to improve national defense strength in the short term.

Even if the negotiations take a very long time, the finished aircraft can be bought directly, and as long as the pilot training is completed, it will be able to take on the heavy responsibility of national defense.

The difference between domestic research and development, even if it has already made its first flight, it will take a constant time to equip the troops.

"It's not a big question in terms of timing. If it really doesn't work, let's equip a batch of F4s first, and as long as we don't do too intense super maneuvering maneuvers, there will be no problem. Liu Yijiu knew what Long Yaohua was worried about.

The Americans offered to sell the F6, an advanced light multi-role fighter, to China.

"Your imitation of the F4 has not yet made its first flight," the old man asked Liu Yijiu with a wry smile.

"The problem of the engine has basically been solved now, and the rest is to need a lot of flight tests to demonstrate the performance of our engines and use them for test flights, and the problem is not too big. After all, the test flight of the fighter is not a performance test of the engine on the air platform, and the time of each flight is very short," Liu Yijiu said with some embarrassment.

Imitation of the F4 fighter, the first flight was postponed again and again.

At first, because of design and processing problems, but later, because of engine problems

"Hurry up. Especially the contact on the part of the Americans, you talk to the Americans with the Commission of Science, Technology and Industry for National Defense," the old man did not say anything more.

Fighter planes are related to a country's national defense and security, and in modern warfare, the first thing is to fight for air supremacy.

Once there is no air supremacy, it will be pressed and hit by enemy fighters, and then the ground forces will be able to advance quickly.

As for the matter of importing technology or fighters from the United States, it is not that the above has not been considered.

The introduction of technology, which makes all the military bigwigs very excited, from the early seventies, the Republic began to design high-altitude and high-speed interceptors, but until now, not a single project has made a breakthrough.

Although there has been a breakthrough in the F4 imitation work of the Ninth Academy, they are now being told that there is a problem with the design of this fighter.

It is not for nothing that the Americans quickly replaced the F4 with a high-low combination of F5 and F6 after a large number of F4 equipment.

"If the Americans want to talk to me, it is estimated that they know about our project to imitate the F4, the specific situation of the Ninth Academy, they don't know, and the Americans really spare no effort to stop the development of our national defense science and technology," Liu Yijiu said with a sigh.

He really didn't want to waste time with the Americans.

"If we can't drag the Americans or solve this problem, the introduced project will definitely not be under our control, and it will not be a good thing for your project in the end." Long Yaohua reminded Liu Yijiu softly.

Liu Yijiu was helpless, "Then let the Americans come to Rongcheng to talk to me, love will not come"

If the Americans sued Liu Yijiu that they would export the technology of such a strategic bomber as the F7 to China, he would definitely agree without hesitation

Although the performance of the F7 fighter is not too strong, and several have been taken down, this is the world's first stealth fighter.

For China, which has a backward industrial base and weak design capabilities, there is a stealth fighter for reference, and when the time comes, a stealth fighter like the US imperialist F22 will be made, as long as the US imperialists dare to go to the small pond in the South China Sea to take a bath, and directly drive the fighter to their aircraft carrier
