Kamal in the air, dense beads of sweat oozed from his nose.

When he was in Europe, he received such training, but he did not expect that when he flew a new plane for the first time in China, he encountered this situation: the pilot induced concussion!

Just when he was falling, he encountered a crosswind, so Kamal skillfully corrected it, but during the correction, the lever was too large, causing the plane to deviate in the other direction, so he corrected it again...

The result of this is that the more corrected, the greater the deviation, which leads to the current pilot-induced concussion!

The swing that is applied with a force to stop the swing should have been pushed in reverse at the lowest point, but now, it has been pushed again when the swing has reached the highest point. As a result, the swing swings even more.

This kind of pilot-induced concussion exists in hydraulically transmitted aircraft, due to the hysteresis of the hydraulic transmission of the aircraft, which leads to the generation of concussion, and in fly-by-wire aircraft, due to the overly sensitive operating system, this situation may also occur.

In an instant, Kamal also thought that this was a pilot-induced concussion, but it was not easy to change it in time.

In later generations, even the American F-22 fell from the plane for this reason.

At this moment, Yang Wei's voice came from the earphones: "Let go of the operating stick!" ”

Let go of the joystick? Without even thinking about it, Kamal released the operating lever, and at this time, a miracle occurred, the plane, which was originally in shock, returned to the state of level flight!

He suddenly remembered that the fly-by-wire system of this aircraft, the flight control rate has been optimized, for example, as long as the operating stick is released, the fly-by-wire system will control the aircraft. Return to level flight!

In complex air battles, in intense training, this function is very useful, and if you don't know your state in the middle of the whirlwind, you just need to release the operating stick, even if it is upside down. The plane will also turn around.

"Go-around, re-landing!" The tower that took over the command shouted.

All of them looked at the sky, watching their fighters finally fly level, turning again, aiming at the runway, and this time, landing steadily.

Everyone breathed a sigh of relief and watched as the cockpit canopy of the fighter plane opened, and Kamal and the radar operator jumped from inside.

"It's not a fly-by-wire problem. It was caused by too many corrections when I was operating. Kamal got down and said to Yang Wei: "The quality of our plane is good, and it is quite sensitive. ”

A sensitive aircraft is a good aircraft, although it is too sensitive, which leads to concussions when landing.

Mhammad, who was next to him, said: "It was changed to a telex operation, and a new problem arose. As a test pilot, I almost had an accident just now. If it were our ordinary air force fighters, I am afraid that it would be more prone to problems. ”

Mhammad's concern is not unreasonable, this kind of fly-by-wire system, while making the operation of the fighter more agile, also requires more well-trained pilots to control it.

"It seems. We have to have a higher education machine. Old Arslan on the side also had a serious expression.

Pilots, as the pride of the sky, are not able to fly fighter jets after learning theory. The meal should be eaten in one bite, and the training plane should be driven in the same way.

After learning the basic knowledge, the first thing the pilot flew was the Chujiao 6, which is a two-seater aircraft with a series of propellers, which looks like a torpedo machine in World War II, which is a Chinese imitation of the Yak-18 aircraft.

This kind of aircraft is used to train new trainees, it is very durable, and the price is also cheap, only 230,000 yuan in later generations, which is not as good as a high-end car, and even the Americans are interested, so they bought a batch from China to train their pilots, and put it in the United States, and turning the yuan into dollars is not enough money for a beginner's training plane.

After flying the propeller of the first Jiao VI and mastering the basic aviation knowledge, the pilot began to fly the Jianjiao VI, which is the transition from subsonic to supersonic, after all, Pakistan was equipped with a large number of J-6 fighters, so many pilots can fly the J-6 fighter directly from the J-6.

Pakistan's trainer aircraft are just like that, so when Pakistan buys American F-16 fighters, the two-seat F-16 is more than the single-seater.

After all, a fighter is used for combat, and the cost of flying for an hour is dozens of times that of a training aircraft.

At the beginning, after Huaxia purchased the Su-27, it also faced the same problem, Huaxia's trainer aircraft is based on the J-7, it is a training aircraft modified on the basis of the J-7, used to train the pilots of the J-7, there is no big problem, but, after flying the J-7, fly the Su-27 directly, then there is trouble, the J-7 is only a backward second-generation aircraft, and the Su-27 is a third-generation aircraft, from the J-7 to the Su-27, the span is too large, resulting in complex and wasteful training of pilots.

In later generations, Pakistan was equipped with a large number of J-7 fighters, so it was necessary to introduce J-7 as a trainer aircraft, and now, Pakistan's first-line main fighters are already third-generation aircraft, and then equipped with this second-generation trainer aircraft, it is definitely not a good choice, so the old Arslan, who is in charge of the Air Force, does not plan to use the J-7 training aircraft.

In the past, Pakistani pilots were trained in the United States and included in the cost of purchasing aircraft, but in the future, more pilots will be trained, which will definitely need to be done by Pakistan itself. In particular, now that we have begun to enter the era of fly-by-wire operation, we need excellent training aircraft.

When Mhammad heard the old Arslan's words, he also nodded: "Yes, there can be no fault in the cultivation of our Air Force talents, and there must be a training aircraft with excellent performance, Arslan, what aircraft do you think is most suitable for us?" ”

"According to the training of pilots in the West, it is necessary to fly three types of training aircraft, the beginner training aircraft, the middle education aircraft and the higher education aircraft." Old Arslan said: "In the junior education machine, we already have the first education six in Huaxia, which is completely okay, mainly the middle education machine and the higher education machine. Among the Chinese education aircraft, the American T-37 is a good choice, and it is said that Huaxia is also developing a Chinese education aircraft called the Jiao-8. ”

The T-37 is a twin-engine jet trainer built by Cessna Aircraft Company of the United States to train pilots and navigators, as well as basic skills such as piloting, instrument operation, formation flight and night flight. Because it is a jet, it is not suitable for pilots who have just learned to fly to master, and it can barely be regarded as a Chinese teaching aircraft, and this kind of aircraft has been put into use since 55 years, and the model has long been old.

Mhammad had never heard of this aircraft, so when he heard about the Jiao-8, Muhammad's expression was suddenly excited: "Yes, just Jiao-8, this is a good training aircraft!" ”

Mhammad from later generations, of course, has heard of the name of this trainer aircraft, in China, this trainer aircraft can be described as one of the few star products, not only equipped with the Huaxia Air Force, but also exported to many countries. Of course, many people may not have heard of the name Jiao-8, but K-8 is definitely heard.

Originally, it was a trainer aircraft, and it did not start with J, but K, because this K word is Karakorum Mountain Karakorum on the border of China and Pakistan, and this aircraft, in history, is a training aircraft jointly developed with Pakistan!

The Nanchang Aircraft Manufacturing Company in Jiangxi Province is famous for its production of training aircraft. Later, watching the continuous upgrading of international fighters, I realized that the training aircraft also needed to improve, so in 82 years, the training aircraft program team was established, with Shi Ping as the leader of the program group, and later served as the main designer. Through market research, the development idea of "improving training efficiency and reducing training costs", the basic performance requirements and the two training systems to meet the needs of different countries have been decided. Moreover, it must be both high and low; Good maneuverability and stall characteristics; Good visibility and a comfortable cabin environment, and much more.

After all, this kind of training aircraft is not a national project, it is completely carried out by the company itself, and this kind of training aircraft needs to enter the international market. So, the starting point for aiming is high.

However, the initial development did not go well, and it was not until 86 that Pakistan joined in, taking a quarter of the investment and producing a part of the body.

In this way, the teaching-8 has become an international cooperation project. The initial target of the equipment was the Pakistan Air Force. Many of the equipment selected are also Western, such as Martin Baker's zero-zero ejection seat, Western electronic flight instrument system, instrument landing system, TACAN navigation system and radio and other mature products in the international aviation market, and the United States Aerospace Equipment Company has cooperated with the United States to equip a high-efficiency environmental control system, and the United States Garrett Company has cooperated to design the intake and exhaust system. Pakistan's accession made the development of the Jiao-8 fast and smooth, solved the problem of serious shortage of funds for military scientific research, and raised the starting point of the aircraft. It has become an advanced aircraft developed by international cooperation.

In history, in 87 years, the specific design of the Jiao-8 began. The manufacture of prototypes began in January '89, and the first flight began in '90. After the finalization, it was first equipped with the Pakistan Air Force, and the domestic model was not finalized until 98. At this time, Nanchang Aircraft Manufacturing Company has also become Hongdu Aviation Industry Group.

However, these are historical things, and now, after Mhammad seized power in Pakistan, Pakistan did not cooperate with Huaxia to carry out the development of this kind of training aircraft, but directly aimed at fighter jets, reverse mapping Tomcats, and thoroughly ate various subsystems, which is the main target of Pakistan. Now, this imitation Tomcat fighter has begun to fly test, and the Jiao-8, which is located in Jiangxi, is still an independent project, I don't know how the progress of development is?
