Chapter 764: Big pie

"Ahem, Teacher Song, Teacher Ben, in fact, we have another way." Tan Zhenhua used a pretended cough to attract the attention of the two teachers who were gazing affectionately at each other and were about to burst into flames.
"What way?" Song Wenhua asked.
"Teacher Song, I said you don’t be angry, our "J-7", unfortunately, the air intake of the nose is unlucky. If it can be changed to the side air intake like Wuye or F-16. The abdomen air intake, can’t the position of the nose be freed? In this way, at least an antenna of 600 mm or more can be installed, even if the power is lower, at least you can see a lot farther, and the place is larger. There is no need for castration."
Song Wenhua said angrily: "What are you laymen doing? Do you think I don't know this? Modify the aerodynamic shape of the aircraft and move the position of the air inlet, which is so simple? You are the same as redesigning an aircraft. The plane is not bad anymore, you know?"
Having said that, Song Wenhua touched his chin after scolding Tan Zhenhua. After Tan Zhenhua's provocation, a plan that had been brewing in his heart for a long time came to his mind irresistibly.
Song Wenhua's current work is not just to prepare for the "No. 10 Project". Another project that has been underway for several years is his main task and is currently the job of the 3611 Institute.
"J-7 III" project.
As we all know, the "J-7" fighter originated from China's imitation of the famous fighter "MiG 21" of the Soviet Mikoyan Design Bureau, but the original intention of the "MiG 21" was originally designed as a front-line air control fighter. The understanding of front-line fighters, cheap, easy to maintain, suitable for mass production of equipment, and able to withstand wear and tear are all necessary conditions. To put it mildly, this is a fighter that was regarded as "cannon fodder" by Soviet Russia, so its internal The equipment is quite simple or even rudimentary.
And this is obviously different from the purpose of the Huaxia equipment "J-7".
The China Air Force regards the "Seven Masters" as its main air superiority fighter, and it is also one of the few "advanced" weapons in its equipment sequence.
Therefore, the army has long proposed improvements to the "J-7" to meet the needs of modern air combat situations.
Unfortunately, China’s weak aviation technology accumulation was not enough to accomplish all of this independently, and the international and domestic political environment at the time determined that it was difficult to obtain foreign aid support. This matter had to be dragged on until one day, a big pie fell from the sky. Le dumbfounded all the scientific research workers of China Aviation Industry.
This matter has to start from the beginning.
From October 6th to October 26th, 1973, the Fourth Middle East War, also known as the "Yim Kippur War" broke out. Egypt and Syria separately attacked the Sinai Peninsula and Ge Lan Heights. A few days before the start of the war, Isaac, who was attacked suddenly and fought on both sides, suffered a lot. The Syrian-Ethiopian coalition forces once had the upper hand, but the good times did not last long. With the arrival of a large number of US military aid, it included providing satellite intelligence. With all kinds of support inside, Isaac, who had slowed down, quickly launched a counterattack, and the situation was reversed.
A week after the war, the Syrian army was defeated and forced to withdraw from the Golan Heights. The Israeli army was able to concentrate its forces on the Sinai Peninsula and besieged the Third Egyptian Army Corps. It crossed the Suez Canal, the ceasefire line between the two sides of the Third Middle East War. .
The Ethiopian troops were defeated. Until this moment, they finally accepted the defeat in desperation and asked the United Nations to intervene in mediation. The two sides ceased the fire. At this time, the leading troops of Isaac had advanced to the Egyptian capital Cairo only 100 kilometers away. s position.
This war has had a profound impact on the world, especially the Middle East. Among them, the defeated Ethiopian class felt the pain of the skin. They believed that the master they had previously trusted was the Soviet Russians who had always been aloof and pointed their fingers at them. After the war, they did not do their utmost to support them; they also believed that Soviet Russia had already shown fatigue in the confrontation between the two poles of the world.
So Egypt changed his position.
In November 1977, the then-Egyptian President Sadat made an unprecedented move-to visit Israel and became the first leader of an Arab country to visit Israel. This also meant that the Egyptian government recognized Israel. The existence of Sa.
In 1978, under the mediation of the United States, Israel returned the long-occupied Sinai Peninsula to Egypt. The two countries signed the famous "Camp David Peace Treaty", which marked the end of the long-term confrontation between Israel and Egypt. Relations normalized and Egypt became the first Arab country to recognize Israel.
And this also means that the Egyptian class is almost completely out of the sphere of influence of Soviet Russia.
It is precisely because of this war that while the Arab countries realize that they cannot defeat Israel militarily, they also realize that they have another weapon in their hands-oil. Therefore, beginning in 1973, Arab oil tyrants united to initiate an oil embargo against the United States, the chief back office of Israel. This move once led to a global recession in the world economy, known as the "first oil crisis" in history.
As for why the final result of the "oil crisis" has evolved into the unbreakable "oil-dollar" system between the United States and Haosha, which allowed the U.S. dollar to lay the most important cornerstone of the international settlement currency in one fell swoop, is it to blame? On March 25, 1975, King Faisal, who had always held a strong stance against Israel, was assassinated in the capital of Riyadh. The political stance of the Dunsha was loosened and turned by Crown Prince Khalid.
Well, this matter has nothing to do with the CIA, please don't associate children's shoes casually...
Back to the topic.
Although the Egyptian class is out of the sphere of influence of Soviet Russia, its Soviet military equipment will not be replaced for a while, because it will cost too much money. The Egyptian class is not as rich as his Arab oil tyrant neighbors. The U.S. is obviously guarded against his newcomer, and he refuses to give too much military assistance. Of course, he should not even think about advanced equipment. In addition, although the relationship with Isaac has been normalized, it seems that he has removed a strong The enemy was regarded as a traitor by the original friends and went out and kicked out of the League of Arab States. The pressure on national defense has not diminished, but has increased.
Without the technical support of the original boss Soviet Russia, wouldn't it be impossible to use some of the wealth that had been accumulated through hard work?
How can a living person suffocate urine?
As a result, the Anglo-Grade very naturally turned his attention to the other one on this blue star who has a lot of experience in the use of Soviet weapons, and has developed a "repair, change and change" ability during the long-term blockade. .
Moreover, Huaxia people don't need any political conditions. The only requirement is small money, and the price is cheap.
After the two sides had a lot of eyebrows and secretive surprises, they hit it off, so a top-secret China Aviation Industry delegation reached the Egyptian level in August 1978. The delegation was a group of 12 people, and the head was the deputy director of Shengfei Factory and 3112 Factory. Tang Gansan, the deputy head is Gu Songfeng, the chief designer of the 3601 Institute of Shengfei.
The results of this visit are very satisfying to both parties. The two parties have established a good cooperative relationship. China Xia has contracted the maintenance and logistics of all Soviet fighters in the Ethiopian class, and promised to provide long-term spare parts supply and meet the requirements of the Egyptian side. Equipment upgrade and modification work, and the Egyptian side has ensured that its weapons and equipment are in a ready-to-use state, ensuring national security.
By the way, our old friend Zhang Qingping, the director of the XAC plant, has also gained a lot of benefits. In addition to undertaking the maintenance of the "Figure 16" strategic bomber with Egyptian-class equipment, he also sold several aircraft. "Hang Liu" is the largest one among the few export businesses of our "Liu Ye".
This time, China’s help made the Egyptian people fully realize the benefits of friendship with China. For this reason, they also received gifts from the China people-after several J-6 fighters, they gave two big gifts in return-one A MiG 21MF fighter and a MiG 23 fighter.
Let’s talk about the MiG 23 later, let’s talk about this MiG 21MF first.
This is the model developed by the Mikoyan Design Bureau on the original MiG 21. The P-13-300 turbojet engine with an afterburner thrust of 6.6 tons has been replaced, and the radar system has been improved. The detection range has reached 20 kilometers. The distance has reached 13 kilometers, and the number of pylons under the wing has been increased to 4, which can mount radar-guided "Advanced Atoll" and K-13A "Atoll" air-to-air missiles, as well as various ground attack weapons or auxiliary fuel tanks. , With zero-zero rocket ejection seats, it can barely be regarded as a multi-purpose aircraft.
For the people in the China Aviation industry who have been groping in the dark, this aircraft was not at all an advanced fighter jet at the time, and many of the technologies on it were not available in itself. Therefore, it was the first time this aircraft was awarded. For a time, the Third Ministry of Machinery and the military immediately decided to copy it!
This arduous task naturally fell on Song Wenhua and his old partner Tu Jida, and the military gave this unborn fighter the "J-7 III".
After hard work, except for some problems with the imitation of the P-13-300 turbojet engine, the entire "J7 III" project is progressing smoothly. The prototype is in the process of manufacturing, and the first test flight should be possible soon. However, the originally not advanced "MiG 21MF" was dragged down by China's weak industrial base. Song Wenhua knew what the performance of the imitation "J-7 III" could achieve. Compare the IAI seen during this period. And Dassault’s products, the gap is not generally large.
To this end, he has thought of many ways, trying to find a cheap, suitable for the upgrade of the "J-7" series of fighters.
And today, now, Tan Zhenhua's words remind him that maybe that plan is really feasible?
Song Wenhua felt that a seed was germinating.
