Test flight is different from ordinary flight. Ordinary flight is to fly a known aircraft with a flight manual to rely on, while test flight is to fly an aircraft without a flight manual, or in other words, they are the people who write flight manuals. They have to explore unknown areas one by one. Even the most dangerous stall and tailspin must be tested and tried to be corrected.

The finalization of a fighter plane is the result of the fearless sacrifice of countless test pilots. A strong national air force needs a group of brave and fearless test pilots!

Although today's flight is very dangerous and exposed the huge defects of the fighter in some aspects, today's harvest is still very great. This fighter will be tested in various aspects to find out the cause of the vibration.

At the scene, Deng Gong and Muhammad praised the two pilots respectively, and gave a speech at the same time, praising countless scientific and technological personnel and test pilots, and then returned to the Xi'an Aircraft Design Institute.

"The Flying Leopard is related to the long-range offensive capability of the navy. Although we have encountered one difficulty after another in the development process, I believe that we will be able to complete the test flight and equip our naval forces." Ma Chenglin, director of the Military Aircraft Bureau of the Ministry of Aviation Industry, who accompanied him, said to Deng Gong.

In history, the Flying Leopard has been discontinued several times, but there are still some people who fully support it. For example, the current Ma Chenglin, Zhang Guozhi of the Science and Technology Department of the National Defense Science and Technology Commission, and Xu Ganquan of the Naval Aircraft Department are very concerned about the Flying Leopard and hope to see the Flying Leopard equipped with troops as soon as possible.

"Our navy lacks long-range strike force, especially our Xisha and Nansha Islands, which are coveted by nearby countries. If we want to guarantee our maritime rights and interests, we must have long-range fighters." Deng Gong also said with emotion.

It is too far away, and no existing fighter can fly there. This is also a major reason why the Flying Leopard can continue to develop. By using two Spey engines with very low fuel consumption, the Flying Leopard has a range of up to 4,000 kilometers and a combat radius of more than 1,600 kilometers.

As they walked and talked, when they came to another workshop, Mr. Deng saw a fighter plane that had been disassembled. His eyes suddenly lit up: "Isn't this a Tomcat fighter?"

This fighter left a deep impression on Mr. Deng. Now, although the fighter plane in front of him was already disassembled, Mr. Deng could still tell it.

In addition to the people from Xifei, there were also many Pakistanis working on the scene.

The engineer in charge of the Pakistani side excitedly reported when he saw the president coming. They had been busy here day and night and did not expect the president to come.

"Report to the president. We are conducting reverse mapping of the Tomcat fighter. The progress is going smoothly. The mapping of all parts has been completed. Structural mechanics analysis is being conducted."

Eastern countries have strong copycat capabilities. How to copy has formed a set of basic steps. Now, if you want to copy the Tomcat, the first step is to conduct mapping.

Measure and map every part of the Tomcat. This is the first step in manufacturing the fuselage, but just mapping is far from enough. Not only do you need to know the layout of the fuselage, but you also need to know why you do this and how each part is stressed. Only then can we fully master this fighter, and when we want to modify it, we can have enough confidence to modify it.

The fuselage of the fighter is composed of a skeleton and skin interwoven with beams and longitudinal beams. First, we need to map and analyze the fuselage.

Muhammad nodded: "This is the first step of our imitation. We don't seek speed, but stability."

"Xi'an Aircraft Industry Corporation is also reverse mapping the Tomcat? How come the Third Ministry of Machine Building doesn't know about this?" At this time, the Minister of the Third Ministry of Machine Building said to Chen Yijian.

"We made a report last time." Chen Yijian said: "But the Third Ministry of Machine Building did not approve it. Later, this project became our own project of Xi'an Aircraft Industry Corporation, raising funds by ourselves and carrying out the project with engineers from Pakistan."

The Third Ministry of Machine Building still supports Shenfei. When it saw that Xi'an Aircraft Industry Corporation had a new project, it immediately suppressed it. However, Xi'an Aircraft Industry Corporation is no longer the Xi'an Aircraft Industry Corporation in history. Through the Spey engine, Xi'an Aircraft Industry Corporation has exchanged a large amount of foreign exchange, which is enough to support the reverse mapping project.

At first, Chen Yijian wanted to abandon the Flying Leopard project, comprehensively survey the Tomcat, and develop a powerful attack aircraft. However, the Third Ministry of Machine Building did not approve it and required the development of the Flying Leopard immediately, and the funding was mainly from the Navy.

So, Xi'an Aircraft Industry Corporation decided to take two steps. On the one hand, it developed the Flying Leopard, and on the other hand, it began to survey the Tomcat. Now it is just the first step of the survey.

"Chairman, Xi'an Aircraft Industry Corporation is carrying out two key projects at the same time, and I am afraid it will be too busy." The Minister of the Third Ministry of Machine Building said: "Why don't we give the task of reverse surveying the Tomcat to Shenfei? Shenfei is originally a key factory for the development of fighter jets. Now, the improvement of the J-82 is nearing completion, and it is completely possible to reverse survey and manufacture the Tomcat."

Hearing the words of the Minister of the Third Ministry of Machine Building, Deng Gong's mind began to think quickly, and this seemed to be a good idea.

"No, I object." Seeing that the Minister of the Third Ministry of Machine Building started to solicit business for Shenfei in front of a foreign president, and did not take him seriously at all, cooperating with Xi'an Aircraft Industrial Corporation was his plan. The two sides began to develop in an orderly manner.

It's not that Xi'an Aircraft has never made a report. In the past, every time it was called, it was suppressed by the Third Aircraft Department. Now, seeing that the project has been carried out normally, I can't wait to move to Shenyang Aircraft, Mhama De was very dissatisfied.

"Our cooperation with XAC and Chengdu Aircraft Corporation of China is proceeding in an orderly manner. We are very satisfied with these two aircraft design institutes and are cooperating with them. We do not want to change to another unit." Mhamad said: "More What's more, our cooperation project was not approved by the Aircraft Department at all, and it was completely developed with XAC's own funds. "

After hearing Mhamad's words, the head of the Third Machinery Department looked embarrassed. He moved his mouth a few times but said nothing.

"Yes, our navy is also very satisfied with the development progress of XAC." Director Xu Ganquan of the Maritime Aircraft Department also said: "Surveying and mapping Tomcat is more related to the future development of our navy. One day, when we If the country's economic strength allows it, we will also start manufacturing aircraft carriers. By then, the Tomcat fighter will be a fighter very suitable for boarding. "

The Air Force abandoned the Feibao project and relied on the Navy's meager capital injection to continue the Feibao. Now, seeing that XAC has developed and has more advanced projects, the Navy very much hopes that XAC will take charge of it.

"However, XAC's technical strength is not enough. The development of Feibao has already made all XAC personnel extremely busy. There have also been many twists and turns in the development of Feibao. I think it is better for XAC to continue to develop Feibao and concentrate all efforts on it." Only with energy can we solve Feibao's problem," the Minister of the Three Machinery Department continued.

"Chairman, we, Xifei, are confident and capable of completing the task of surveying and mapping the Tomcat." Chen Yijian held his breath and said to Deng Gong.

Obviously, Mr. Deng was still hesitant.

After all, Xifei's technical strength is really not strong enough. A flying leopard takes up too much of Xifei's energy.

"I think XAC can cooperate with Chengdu Aircraft Corporation of China," said Mhamad. "Mapping the Tomcat's airframe is only the first step. We not only need to imitate it, but also transform it. In addition to replacing it with newer ones, In addition to the fire control system, there is also a control system that requires the control of the Tomcat fighter jet to be replaced by a four-degree digital fly-by-wire operation. It seems that Shenfei has an advantage over Shenyang Aircraft Corporation in that it does not have the ability to develop a four-degree redundant aircraft. Digital telex?"

Hamad looked at the director of the Third Machinery Department. Sure enough, the other person was mute and stopped talking.

Chengdu Aircraft is currently working on Project No. 10, which has become a national key project. In order to pursue good aerodynamic performance, a canard layout is used. The main delta wing is at the back, and a movable canard is used in the front to achieve a performance leap. However, the canard layout is inherently unstable and must be controlled by a fly-by-wire system.

Therefore, Chengdu Aircraft has been overcoming the difficulties of digital telex. After they overcome it, both Feibao and Tomcat can be replaced by digital telex.

The Tomcat was born in 1972. At that time, digital telex was just an imagination. Without modern advanced electronic technology, there would be no such control.

Therefore, the early Tomcats used hydraulic operation. Of course, although it was hydraulic, it was much lighter than the MiG-29.

In the later period, a modern improvement of Tomcat was digital telex.

When the early Tomcat fighters carried many expensive and heavy high-value ammunition, such as six Phoenix missiles, when they returned to the mothership, due to various reasons, such as fast landing speed, etc., some of them had to be used to ensure the safe return to the mothership. . Grumman's later improvements were to increase the size of the wing and equip it with a new flap-aileron structure that increased lift. At the same time, a fly-by-wire control system was used to help control the wing surface more accurately; when the ailerons were lowered, early The F-14 needs to adjust its aerodynamic center of gravity to eliminate the nose-down moment generated by the ailerons. After using the four-redundant fully digital fly-by-wire control system, the improved winglets generate lift to offset the sinking moment. These improvements allow the Tomcat fighter to carry more than two tons of ammunition back home, and the landing speed is reduced. After eliminating the nose sinking moment, the tail heaviness is reduced when maneuvering, and the air combat maneuverability is increased by about 20%. , steering flexibility is also improved.

Therefore, while surveying and mapping to imitate the Tomcat, it is essential to use telex operation to give the Tomcat more powerful performance. However, just this four-redundant digital telex is something that Shen Fei cannot handle. (To be continued ~^~)
