MiG-21, a backward second-generation aircraft, can it compete with the current advanced fighter jets? What a joke! Although I am quite satisfied with the cost-effectiveness of second-generation aircraft like MiG-21, it is still impossible to believe that this aircraft can fight third-generation aircraft one-on-one.

Needless to say, others don’t believe it. At this time, even Tu Jida himself doesn’t believe it! Can this kind of fighter have such advanced combat power? Confronting third-generation aircraft? In China, that is, the J-82, and its own J-7 are only worthy of being soy sauce!

Egypt's air force commander was obviously very interested. Although after the Fourth Middle East War, Egypt sought peace with Israel alone and negotiated to return to the Sinai Peninsula. This method caused Egypt's status in the entire Middle East to plummet, and Egypt did not explain anything and kept going to develop itself.

Egypt is well aware of its military gap, especially the Air Force, which needs an advanced fighter jet to replace its old fighter jets. This time they come to Moscow, they really need to order fighter jets.

However, among the two Soviet fighter jets, the Su-27 was a high-end aircraft. Although they were interested, the Soviets were not willing to sell them. Although Andre said it was so high-sounding, it was not so easy to order. After all, Egypt's withdrawal from the war with Israel actually made the Soviet Union quite dissatisfied. Moreover, due to limited funds, Egypt may not even have enough funds to order MiG-29.

Egypt needs a new fighter jet that can compete with third-generation aircraft, but also has a good cost-effective fighter jet!

In fact, after learning about Egypt's needs, the French Phantom Company immediately contacted Egypt and tried its best to sell the Phantom 2000 fighter jet to Egypt. Egypt was very satisfied with the performance of the Phantom 2000, but for the price of this aircraft, they could only hold their pockets tightly and continue to make choices.

The MiG-29 of the Soviet Union is already in the export sequence. Syria, Iraq and other countries have already equipped this fighter jet. However, the unit price of the MiG-29 is now around 30 million rubles, and Egypt really doesn’t have much capital!

So, they were also moved when they heard Andrei say that this J-7 was modified and could fight against the third-generation aircraft.

Tu Jida was of course even more moved. He didn't say anything and listened to Andre's continued explanation.

"The biggest problem with the MiG-21 series fighter jets is the air intake. This method causes the inability to place radars with a large enough diameter, which will lose the ability to fight the middle-range air combat. In today's era, medium-range air combat has become the standard style of air combat. Moreover, without advanced radars, it will lack the ability to perceive the surrounding airspace." Andre said: "So, we can improve the MiG-21 fighter jets, change the air intake to the air intake on the belly, so that the precious space of the nose can be freed up, and large radars can be installed to obtain the ability of medium-range air combat."

Modify the nose! If you want the J-7 to have good combat capabilities, you must improve the nose! In history, this improvement for the J-77 was only started in 1996. At that time, the J-7fs was designed, which was the way to intake air at the lower chin, while the J-7mf was changed to air intake at the belly, which completely solved the problem of the nose.

Originally, radar could only be installed in the air inlet rectifier cone, so the size of the radar scanning antenna was strictly limited. If it was too large, the intake volume would be reduced and the engine could not meet the normal working requirements. Therefore, the J-7m brought by Chengfei now uses the "Air Patrolman" 226 fire control radar of Gec-Marconi. The effect range is basically about 20 kilometers. It can only track/attack a single target, and cannot give fighter aircraft the ability to conduct visual range of outer air combat. After all, this radar is just to help close-range missiles and even machine cannons better aim at the target.

"In modern fighter jets, the performance of large angle of attack is the most important, so air intake on the belly is the most suitable choice." Andre said: "Through such improvements, the defects of the original MiG-21 can be compensated."

Changing the nose! This idea has actually appeared in Tu Jida's mind for a long time, but the improvement of his J-7m is a small fuss. If it is improved to intake the nose, it would be a major operation! Cheng Fei does not have enough funds to make such a struggle, and there is no suitable radar replacement now!

Marconi's radar is not suitable, and we have to find new radars. Moreover, if the nose becomes larger and the center of gravity of the whole machine moves forward, we have to rebalance. The workload is not an ordinary large amount!

Even in the discussion of the new model, we have designed the model of the air intake solution for the belly of the machine and had wind tunnel experiments, but it is a huge workload to actually deal with it.

"The MiG-21 appeared in the 1960s, and its design was indeed outdated. Therefore, in addition to improving the nose, we can also consider improving the MiG-21's wing shape and using advanced aerodynamic technology to bring the combat performance of this aircraft to a higher level." Andre said.

Is it necessary to change the wings? Tu Jida's brows gradually frowned. Is it necessary to design a new aircraft?

"General Andre, you should know that the current trend of military aircraft development is to use turbofan engines. Although the initial procurement cost is higher, the later use cost is low. The fuel consumption rate of the turbofan engine is small, making it more convenient for logistics maintenance." At this moment, the commander of the Egyptian Air Force said: "No matter how the nose and wings of this J-7 are improved, it will still not satisfy people if the engine is not replaced."

Turbine fan engine! Blowing air to the outer duct through the front fan, it directly turns into thrust, greatly reducing fuel consumption. It is the trend of the development of military aircraft in the world. The current advanced third-generation aircraft are all using turbine fan engines.

If the J-7 does not replace the turbofan engine, the performance will still not be improved!

"This question is very good! If you only focus on the initial procurement cost, the turbojet engine is very cheap. If you focus on the cost of the entire service period, the turbofan is the better choice. In fact, it is not difficult to install the turbofan for the J-7. Our rd33 engine can be equipped with the J-7, which can greatly improve performance, and at the same time greatly reduce the fuel consumption rate and increase the range of the J-7. As long as you modify the rear fuselage, there will be no problem."
