f4 has huge hidden dangers

This shocked several people.

"Is this true? Even if we imitate it, our Air Force will not be able to equip it?" The old man was also moved.

It is obvious that China will have the most advanced fighter jets in the world. Although the performance may be a little worse, it will definitely not be too many. As long as it is equipped with dozens of such fighter jets, it can greatly improve the national defense security of the Republic, especially the northern border.

On the Iranian battlefield, the performance of the F4 fighter jet is quite good, although it has also lost a lot.

"Equipment is OK, but it is still far from what we imagined. Because this fighter cannot perform super maneuvering at too high speed, in war, it is likely that the fighter will disintegrate because the fighter performs super maneuvering when avoiding faster missiles. This time, our test flight was not because of the engine problem, but because of the fighter itself. When maneuvering at high speed, huge overload will cause some systems inside the fighter to fail." Liu Yijiu explained immediately.

The strength structure of the f4 fighter has problems. Even if the connection is thickened on the roots where the wings and fuselage are combined, 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 frowned and asked. If this happens, things will be really a bit troublesome.

The Air Force must have a more advanced fighter jet, and current national defense needs.

"I'm awake. I also reported the situation he encountered on the fighter. During the operation, there was no alarm at the beginning. When doing the super cobra maneuver, the rotation of the fighter made the joystick a little inflexible. According to the introduction of the Iranian combat hero, most of the F4 fighters lost by Iran were caused by the failure of the fighter itself, rather than being shot down by the French F." Liu Yijiu and others have investigated it clearly.

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

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

"If our air force wants to equip advanced fighter jets, it must have better performance. After all, our military expenditure is not enough to support us. And when fighter pilots really encounter failures, they will not give up fighter jets to save their lives. This makes us have to provide them with more reliable fighter jets. In order to cope with more enemies, they must have higher maneuverability. For example, Cobra maneuver is very useful when avoiding missiles and locking the enemy chasing from the rear; Super Cobra maneuver, which can not only avoid it. It can also avoid the enemy behind when chasing in the air from this maneuver, and go around behind the enemy fighter jets." Liu Yijiu explained the role of the maneuver tactical actions of these fighter jets.

The Republic Air Force actually has higher performance requirements for fighter jets.

Because the Republic cannot equip advanced fighter jets in large quantities like the United States and the Soviet Union.

The United States was able to equip a large number of advanced fighter jets because the United States had a huge economic foundation and its national fiscal deficit reached trillions of dollars; the Soviet Union was able to equip it not because they had a good economic foundation, but because the Soviets had always paid no cost in this regard, and they needed to have more equipment than the United States and even the entire NATO alliance.

During World War II, Germany attacked the Soviet Union, and the advanced Tiger tank was flooded by the torrent of Soviet t34 tanks.

Especially the Soviet Minister of Defense Ustinov came to power. His requirement was that weapons could be easily manufactured and could be equipped with troops on a large scale very quickly.

China cannot do it, its economy cannot do it, and its industrial foundation cannot do it.

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

"I know this point. Even if the J-8 ii is equipped with pulse Doppler radar, it cannot compete with the Soviet MiG-29 and the Su-27 that are equipped with troops. No matter how much it should be, the J-1i cannot enter the range of the third-generation fighter jet." Liu Yijiu sighed.

The J-7 is originally a counterfeit model of the MiG 2. The J-8 was also developed based on the J-7.

The Soviet Union developed the MiG 23 and MiG 25 based on the MiG 2, and the MiG 29 has also come out.

Every new model has a very big improvement.

If you only talk about performance, compared with the Su-style MiG family, the J-7 and J-8 are much worse than the MiG 25, and it is even less likely to achieve high-altitude and high-speed performance like the MiG 25.

"But the f4 body structure, especially the connection between the wings and the fuselage, the fuselage skin, etc., cannot withstand too much overload. The internal hydraulic system will have problems when maneuvering at high speed, and the freight-speed system will also have problems."

f4 was studied by Americans and produced by them.

But the one who plays the best F4 fighter is the Iranians, who drives F4 and participates in too many practical combat; and the one who knows the most about F4 has become Chinese, and Americans will never have crazy characters like Liu Yijiu. During the experiment, they let the pilots do various dangerous actions, and eventually discovered such problems by accident.

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

"The improvement work is actually underway, and the giant panda project is modified to f4." Liu Yijiu introduced the situation of the giant panda project.

The giant panda project completely combines the advantages of Su27 and F4. The aerodynamic layout completely surpasses F4, and its performance is much stronger than Su27. The performance of the turbofan is also better than that of the engine Al3 used by Su27.

The only thing that is the avionics system and the radar system are the worst.

This can be made up for maneuverability.

"Although the manufacturing of new prototypes has begun, it takes time to conduct the first flight ground static pressure test, wind tunnel experiment, etc.," Long Yaohua said with a frown. "Those people won't give you much time."

For many people, the introduction from abroad can improve their national defense strength in the short term.

Even if the negotiation takes a very long time, you can buy the finished aircraft directly. As long as the pilot training is completed, you can take on the heavy responsibility of national defense.

The difference between research and development in China is that even if you have already made a first flight, it will take a constant time to equip the troops.

"There is not a big problem in time. If it really doesn't work, we will equip a batch of F4s first. As long as we don't do too intense super maneuvering, there will be no problem." Liu Yijiu knew what Long Yaohua and the others were worried about.

The Americans offered to sell advanced lightweight and multi-purpose fighter jets like F6 to China.

"The f4 you imitated hasn't had its first flight yet, right?" the old man asked Liu Yijiu with a wry smile.

"The engine problem has basically been solved now. The rest requires a lot of flight tests to prove our engine performance and use it for test flights. The problem is not too big. After all, the test flight of the fighter is not the performance test of the engine on the air platform, and each flight time is very short," Liu Yijiu said a little embarrassedly.

The first flight of the imitation F4 fighter was delayed again and again.

At the beginning, due to design and processing problems, but later, due to engine problems

"Save the time. Especially for the contact between Americans, you can talk to the Americans with the National Defense Science and Technology Commission." The old man didn't say anything else.

Fighter jets are related to a country's national defense and security. Modern warfare is the first thing to do is to compete for air supremacy.

Once there is no air supremacy, it will be suppressed by enemy fighters, and the ground forces can advance quickly.

The above has considered the introduction of technology or fighter jets from the United States.

The introduction of technology has made all military tycoons extremely tempted. Since the early 1970s, the Republic has begun to design high-altitude high-speed interceptors, but now, no project has made breakthrough progress.

Although the F4 imitation work of the Ninth Academy has made breakthrough progress, it is now telling them that there are problems with the design of this fighter.

After the Americans equipped the f4 in large quantities, they quickly replaced f4 with f5 and f6 in high and low matching, which is not unreasonable.

"The Americans want to talk to me, probably because they know our imitation F4 project and the specific situation of the Ninth Academy. They don't understand it. Americans really spare no effort to prevent the development of our national defense technology," Liu Yijiu said with a sigh.

He really doesn't want to waste time with Americans.

"If you can't drag the Americans to the point where this problem is solved, the projects introduced will definitely not be under our control, and in the end it will not be a good thing for your projects." Long Yaohua whispered to remind Liu Yijiu.

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

If the Americans told Liu Yijiu that they exported the technology of strategic bombers like F7 to China, he would definitely agree without hesitation

Although the performance of the f7 fighter is not too powerful and has been shot down several times, this is the world's first stealth fighter.

For China, which has a backward industrial foundation and weak design capabilities, there is a stealth fighter for reference. At that time, it will create a stealth fighter like the US F22. As long as the US dares to run into a small pond in the South China Sea to take a bath, they will directly drive the fighter to their aircraft carrier heads
