It is also beneficial to study the two simultaneously and learn from each other. Yang Wei has made a lot more progress in his understanding of the telex system.

For Tomcat fighter jets, the most difficult thing is to control the variable sweep wing. The Soviets' solution was manual adjustment, but the United States was already computer-controlled. Therefore, what Yang Wei needed to do was to add this control to the telex developed by himself.

Of course, during the development, Pakistani technicians also worked together. On the scene, there were Pakistani technicians. Over the past two years, the two sides have become good friends.

Installed test flight! Since the Tomcat fighter is already a mature fighter, the modified digital telex is improved by analogy with previous hydraulic operations, and the difficulty is less. Now the initial development has been completed. What is the effect? ​​The test flight is still required.

However, looking at the Tomcat fighter jet on the Iron Bird Stage, Song Wencong also knew that it was very difficult.

After all, this Tomcat fighter was provided by Pakistan to conduct reverse surveying and mapping. After each component was surveyed and mapped, it also conducted tests on static pressure and other aspects to determine the strength of each position. Therefore, the skeleton looks strong, but there are already metal fatigue in many places, which is caused by excessive pressure during the experiment. Even if the aircraft is assembled, it is afraid that it will not be able to fly, which will be dangerous.

In this way, if you want to modify the telex and install the test flight, you need another one. If you want another plane from Pakistan? This seems a bit too much. After all, this Tomcat fighter is a front-line fighter of the Pakistan Air Force. If you pull it out for research, Pakistan will be quite generous. You can't make a second one. If it falls during the test, how can you be worthy of Pakistan?

"Mr. Song, Mr. Yang, someone outside the institute wants to see us." At this moment, a duty staff member said.

"Who?" asked Song Wencong.

"Consulate of Pakistan."

"Please invite him in." Song Wencong said quickly.

Pakistani Consul! Pakistan has a deep friendship with China. At the same time, the diplomatic relations between the two sides are also very close. In addition to setting up embassies in the capital, Pakistan also set up consulates in Shanghai, Guangzhou and Chengdu, each in charge of one party.

Pakistan's Consul General in Chengdu is Kakhalid. Due to the military trade cooperation between the two sides, Kakhalid often comes to Chengfei.

"Mr. Song and Mr. Yang, I'm very happy to see you." Kahalid was tall, wearing a short beard and wearing a suit, showing a capable performance.

"We are also very happy." Song Wencong said: "Consul General comes to Cheng Fei, what's wrong?"

"Our president is very concerned about the reverse mapping of Tomcat fighter jets, so let me come and see how it is going," said Kahalid.

Progress? Before Song Wencong spoke, Yang Wei, who was standing beside him, said: "It's going smoothly. In terms of fuselage, Xifei has done almost everything. In terms of flight control, we have completed reverse mapping. Now we only need a complete Tomcat fighter, modify our telex flight control, conduct tests, and see how the effect is."

Now we are facing this problem. Since the Pakistani consul is here, Yang Wei is born as a calf, so he has no shame.

"You mean, do you want us in Pakistan to provide another Tomcat fighter jet to improve it into digital telex?" Kahalid asked.

"Yes." Yang Wei answered very simply without any hesitation.

"Okay, I will report to the country." Kahalid told Yang Wei: "If we can provide a new fighter jet, how long will it take to test the digital telex before it can be put into use?"

"We need to go through a rigorous test flight, which will take about a year." Yang Wei said: "Of course, if there are pilots from your country who are familiar with Tomcat fighter jets to test flights, it will be the best."

Digital flight control has been developed, and Pakistan needs another aircraft! When the news came back to Pakistan, Mhamad just frowned and said, "Since that's the case, we can provide one, and at the same time, send our best pilot to test flight this modified flight control fighter."

Mhamad agreed very happily, which was a must. Moreover, if the effect was good, the original aircraft could be improved into digital telex, which could further improve the performance of the fighter.

Of course, digital flight control is very difficult, and there may even be a drop in the middle, Mhamad is mentally prepared.

"Now, the flight control has entered the test flight stage. I think our fuselage can actually start construction." Mhamad continued: "In this way, while building, waiting for the flight control to be improved, we can produce it in small batches even if we don't order it from the United States."

When producing aircraft, it is not about producing cars. Just as assembly lines are enough, the progress of producing aircraft is very slow.

In later generations, the J-10 was already the most equipped fighter jet in China, with an annual output of only more than twenty. Now, Pakistan's Tomcat fighter jets, in the early production and running-in of the production line, will definitely be single-digit numbers, and everything needs to be explored.

"As for the initial production base, it's up to us." Mhamad thought for a while and continued. Pakistan needs to develop its own aviation industry. Now, Pakistan also has the strength to build a new aircraft production line. This is the first time Pakistan has produced a whole aircraft, but it will gradually increase in the future. Mhamad is confident about this.

Anyway, I am also exploring now. I invite some technicians from China and teach by words and deeds to bring out a large number of qualified technicians. You should know that building aircraft requires a large number of senior technicians. Now, Pakistan's technical schools are constantly cultivating the blue-collar class.

This is not a great leap forward, it is a necessary process!

Hearing Mhamad's ambition, Musha Af said: "The President's husband, the West Flight side, has heard from news that although they have mastered all the structures, they are still powerless to do something about some components."

Some components? Mhamad asked, "What components?"

"The titanium beam and large frame of the body," Musha Af said.

In order to make the aircraft light and have sufficient strength, the body must use titanium alloy components, which penetrate the full-length beam and cross the large frame to form the frame.

The world's advanced aircraft, including the su-27, are made of titanium alloy skeleton structure.

However, in the prior art, it is difficult to make the skeleton of titanium alloy. Even the Su-27 was not used as the Su-27, because the Soviet Union lacked advanced titanium alloy processing capabilities, the titanium alloy frame of the fuselage was manufactured in sections and then synthesized by electron beam welding. The weld strength was much lower than the overall forging, which seriously affected the structural strength and fatigue life. In China, the J-7 and J-6 produced in large quantities in China use almost no titanium alloy, and are mainly used on engines. Therefore, the processing capacity of titanium alloy is also very lacking.

The Tomcat fighter is not only a fuselage frame, but also a titanium alloy component as the main component of the variable sweep wing.

"We can introduce technology from the West." Mhamad said: "Aren't the British short of money now? We can introduce large machine tools from the UK, and the island countries can do it too. The machinery and equipment of the island people is also quite advanced. We also need to introduce large forging presses to completely solve the problems of these components."

The advantage of Pakistan is that it has channels for Western exchanges, and now there is enough funds, so Mhamad immediately decided to introduce technology from the West, improve equipment at home, and directly have the processing capabilities of these large components.

"It seems that our investment will be quite large," Musha Af said.

I'm afraid I'll have to throw it in again hundreds of millions of dollars.

"In the short term, it may be more cost-effective for us to directly import fighter jets, but if we want to cultivate our own aviation industry, we need to make a lot of investment in the early stage." Mhamad said: "In the future, we will gradually recover profits. For example, we can sell the fighter jets we produce to Saudi Arabia and other countries in the future. I think Saudi Arabia is more willing to use our fighter jets. We will gradually enter a virtuous cycle. Of course, now is our most difficult time, and at the same time, we must also guard against Americans."

Americans would not see a powerful industrial power in South Asia, especially a country that also copied their Tomcat fighter jets. In order to introduce the F100 production line, Mhamad had a lot of thought and even used the concept of stealth in later generations to fool the Americans, and finally was able to produce this engine in Pakistan.

Therefore, the United States is more careful about Pakistan and will not allow Pakistan to have the ability to manufacture the entire machine. Although it will definitely not be able to hide it from Americans in the future, now it can at least count on the calculation of hiding it every day.

"The new factory needs to be selected for another factory, and cannot be in the original overhaul factory." Mhamad continued: "We can consider establishing a branch in the southern coastal areas."

The original J-6 repair factory was transformed into a factory that overhauled the Tomcat fighter jets, and improved there to become a factory that produces Tomcat fighter jets, which seemed more appropriate, but Mhamad had more considerations and opening another factory in the south was definitely a more suitable choice.

Of course, in this way, time may be dragged backwards. When the test flight of the cat that was operated by the telexed tomcat is completed, it will be more appropriate.

"Okay." Musha Af said: "This matter is related to the development of our Pakistani armed forces, and we will definitely resolve it properly."

"Report." At this moment, an adjutant walked in and said to Mhamad: "China invites our naval formation to go to China for a friendly visit." (To be continued...)
