Test flights are different from ordinary flights, ordinary flights are flying known airplanes with flight manuals to rely on, while test flights are flying planes without flight manuals, or rather, they are the people who write flight manuals, they have to explore unknown areas, and even the most dangerous stall tailspin must be tested and tried to change it.

The finalization of a fighter plane is the fearless sacrifice spirit of countless test pilots, and a strong national air force needs a group of heroic and fearless test pilots!

Although today's flight was very dangerous, and it exposed that the fighter had huge flaws in some aspects, today's gain was still great, and this fighter will be tested in all aspects to find out the cause of the tremor.

At the scene, Deng Gong and Mhammad praised the two pilots respectively, and made a speech at the same time, praising countless scientific and technological personnel and test pilots, and then returned to the Xifei Design Institute.

"The Flying Leopard is related to the navy's long-range offensive capability, and although we have encountered one difficulty after another in the process of development, 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 dismounted several times, but there are still some people who are fully supporting, such as the current Ma Chenglin, Zhang Guozhi of the Ministry of Science and Technology of the Commission of Science, Technology and Industry for National Defense, and Xu Ganquan of the Ministry of Marine Aircraft, who are very concerned about the flying leopard, hoping to see the flying leopard equipment troops.

"Our navy lacks long-range strike forces, especially our Xisha and Nansha Islands, which are even more eyed by nearby countries and want to ensure our maritime rights and interests. It is necessary to have long-range fighters. Deng Gong also said with emotion.

It was too far away for any of the existing fighters to fly, which was why the Flying Leopard could continue to develop, using two Spey engines with very low fuel consumption, and the Flying Leopard had a range of up to 4,000 kilometers and a combat radius of more than 1,600 kilometers.

While walking. While chatting, when he walked to another workshop, Deng Gong saw a fighter plane that had been disassembled and disassembled, and his eyes suddenly lit up: "Isn't this a Tomcat fighter?" ”

This kind of fighter left a deep impression on Deng Gong, and now, although it is a disassembled fighter in front of him, Deng Gong can also see it.

In addition to the people who flew west, there were many Pakistanis working on site.

Engineer in charge on the Pakistani side. Seeing the president coming, he excitedly reported, they have been busy here day and night, and they didn't expect the president to come.

"Report to the President, we are working on the reverse mapping of the Tomcat fighter, and the progress is progressing, the mapping of all components has been completed, and the structural mechanics analysis is underway."

Eastern countries. has a strong copycat ability, how to imitate. A basic set of steps has been formed, and now, if you want to imitate a Tomcat, the first step is to carry out mapping.

Every part of the Tomcat is mapped, which is the first step in the manufacture of the body. However, it is not enough to simply carry out mapping, not only to know the layout of the body, but also to know why it is done. What is the force of each component, so that you can fully grasp the fighter, and finally when you want to modify, you can also have enough confidence to modify.

The body of the fighter is composed of a skeleton and skin intertwined with beams and longitudinal beams, and the body needs to be mapped and analyzed first.

Mhammad nodded: "This is the first step of our imitation, we don't seek speed, we must be stable." ”

"Xifei is also reverse-mapping Tomcats? How come the Third Machine Department doesn't know about this? At this moment, the minister of the Third Machine Department said to Chen Yijian.

"We reported last time." Chen Yijian said: "However, the Third Aircraft Department did not approve it, and later, this project became our own project of Xifei, which was self-financed and carried out with engineers from Pakistan. ”

The Third Aircraft Department is still supporting Shen Fei, and when it saw that there was a new project in Xifei, it immediately pressed down, but Xifei is no longer the Xifei in history.

At the beginning, Chen Yijian very much wanted to give up the Flying Leopard project, comprehensively map the Tomcat, and develop a powerful attack aircraft, but the Third Aircraft Department did not approve it, and demanded that the Flying Leopard be developed immediately, and moreover, it was mainly the Navy's funds.

So, Xifei decided to go on two legs, on the one hand, to carry out the development of flying leopards, and on the other hand, to start surveying and mapping Tomcats, and now it is just the first step in surveying and mapping.

"Chairman, Xifei is carrying out two key projects at the same time, I'm afraid I can't be busy." The minister of the Third Aircraft Department said: "Why don't we hand over the task of reverse mapping Tomcats to Shen Fei, who was originally a key factory for the development of fighter aircraft, and now, the improvement of J-82 is nearing completion, and it is completely possible to carry out reverse mapping and manufacturing of Tomcats." ”

Hearing the words of the minister of the Third Machine Department, Deng Gong's mind began to think quickly, this seemed to be a good idea.

"No, I'm against it." Looking at the minister of the Third Aircraft Department, in front of himself, a foreign president, he began to buy and sell Shen Fei, and he didn't take himself into account at all, cooperating with Xifei, this was his own plan, and the two sides began to develop it in an orderly manner.

It's not that Xifei hasn't made a report, in the past, every time he called, he was suppressed by the Third Aircraft Department, and now, seeing that the project has been carried out normally, he can't wait to move to Shen Fei, and Muhammad is very dissatisfied.

"Our cooperation with Xifei and Chengfei is being carried out in an orderly manner, we are very satisfied with these two aircraft design institutes, and we are cooperating, and we do not want to change to another unit." Mhammad said: "What's more, our cooperation project was not agreed to by the Third Aircraft Department at all, and it was completely developed by Xifei with its own funds." ”

Hearing Mhammad's words, the minister of the Third Machine Department looked embarrassed, moved his mouth a few times, and said nothing.

"Yes, our navy is also very satisfied with the development progress of Xifei." Minister Xu Ganquan of the Ministry of Marine Aircraft also said on the side: "Surveying and mapping Tomcat, more related to the future development of our navy, one day, when our country's economic strength allows, we will also start to manufacture aircraft carriers, when the time comes, the Tomcat fighter will be a very suitable fighter for ships." ”

The Air Force gave up the Flying Leopard project, and it was all thanks to the Navy's meager financial injection that the Flying Leopard continued, and now, seeing that Xifei has developed and has more advanced projects, the Navy very much hopes that Xifei will preside over it.

"However, the technical strength of Xifei is not enough, and the development of the flying leopard has made all the personnel of the flying leopard busy, and the development of the flying leopard has also had a lot of twists and turns. The head of the Third Machine Department continued.

"Chairman, we fly west, and we have the confidence and ability to complete the work of mapping Tomcats." Chen Yijian held his breath and said to Deng Gong.

Obviously, Deng Gong was still hesitant.

After all, Xifei's technical strength is really not strong enough, and a flying leopard will involve too much energy in Xifei.

"In my opinion, Xifei can cooperate with Chengfei." "Mapping the Tomcat's body is only the first step, and we don't just want to imitate it, we have to modify it," Mhammad said. In addition to the updated fire control system, there is also a control system, which requires the control of the Tomcat fighter to be replaced with a four-degree digital fly-by-wire operation. These, Cheng Fei has more advantages than Shen Fei. It seems that Shen Fei has no ability to develop four-degree digital telex at all, right? ”

Muhammad's eyes looked at the minister of the Third Machine Department, and sure enough, the other party was dumb and stopped talking.

In order to pursue good aerodynamic performance, the canard wing layout is used, the main delta wing is in the back, and the front is through the guò movable canard wing to achieve a leap in performance, however, the canard layout has a natural instability, and it is necessary to use a fly-by-wire system to be able to control it.

Therefore, Cheng Fei has been overcoming the difficulties of digital telex, and when they overcome it, whether it is a flying leopard or a tomcat, they can be replaced by digital telex.

The Tomcat was born in '72, at a time when digital telex was just an imagination, and without modern advanced electronics, there would be no such control.

Therefore, the initial Tomcat, which used hydraulic operation, of course, although hydraulic, was also much lighter than the MiG-29.

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

Many of the expensive and heavy high-value ammunition carried by the early Tomcat fighters had to be returned to the mothership for various reasons, such as the six Immortal Bird missiles, to ensure a safe return to the mothership. Grumman's later improvements were to increase the size of the wing, equip it with a new flap-aileron structure that increased lift, and use a fly-by-wire system to help control the wing surface more precisely. When the aileron was lowered, the early F-14 needed to adjust the aerodynamic center of gravity to eliminate the nose sinking moment generated by the ailerons. After using the four-redundancy all-digital fly-by-wire control system, the improved winglets are used to generate lift and offset the sinking moment. These improvements allowed the Tomcat to return home with more than two tons of ammunition and a 12-knot reduction in landing speed; After eliminating the sinking moment in the nose, the feeling of heaviness at the tail is reduced when maneuvering, the maneuverability of air combat is increased by about 20 percent, and the steering flexibility is improved at the same time.

Therefore, while surveying and mapping the imitation Tomcat, it is indispensable to use fly-by-wire operation to make the Tomcat have more powerful performance, and only this four-degree redundant digital telex is something that Shen Fei can't handle. (To be continued......)
