Dominate South Asia

Kamal in the air had thick beads of sweat on his nose.

When he was in Europe, he received such training, but he never expected that when he flew a new aircraft in China for the first time, he would encounter this situation: pilot-induced concussion!

Just when he was falling, he encountered a gust of cross wind, so Kamal skillfully made corrections. However, during the correction, the stick was too large, causing the plane to deflect in another direction, so he made corrections again...

The result of this is that the more corrections are made, the greater the deviation, which leads to induced concussion in current pilots!

Just like applying a force to stop the swing, it should have been a push in the opposite direction at the lowest point, but now, it has become a push again when the swing reaches the highest point. As a result, the swing swings more.

This kind of pilot-induced oscillation exists in hydraulically driven aircraft. Due to the hysteresis of the aircraft's hydraulic transmission, oscillations occur. On fly-by-wire aircraft, the operating system may be too sensitive. This situation occurs.

For a moment, Kamal also thought that the concussion was induced by the pilot, but it was not easy to correct it in time.

In later generations, even the American F-22 crashed out of the plane for this reason.

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

Let go of the lever? Kamal released the control lever without thinking. At this moment, a miracle happened. The plane that was in shock returned to level flight!

He suddenly remembered that the fly-by-wire system of this aircraft had optimized the flight control rate. For example, as long as the control stick was released, the fly-by-wire system would control the aircraft. Return to level flight!

In complex air battles and intense training, this function is very useful. When the world is spinning and you don't know your status, you just need to release the control stick. Even if it is upside down, the aircraft will turn around.

"Go around, land again!" shouted the tower, which took over the command.

Everyone looked at the sky, watching their fighter plane finally fly level. He turned again, aimed at the runway, and this time landed steadily.

Everyone breathed a sigh of relief as the canopy of the fighter plane opened and Kamal and the radar operator jumped out.

"It's not a problem with the fax system, it's caused by too many corrections when I was operating it." Kamal came down and said to Yang Wei: "The quality of our aircraft is good and it is quite sensitive."

A nimble aircraft. It would be a good airplane, although it was too sensitive and caused vibrations during landing.

Mhamad, who was next to him, said: "It has been changed to a telex operation. A new problem has arisen. As a test pilot, we almost had an accident just now. If we are ordinary air force soldiers, I am afraid that problems will be more likely to occur." "

Mhamad's worries are not unreasonable. This telex system not only makes the operation of fighter planes more sensitive. It also requires more trained pilots to control it.

"It seems that we must have a higher education machine." Old Arslan on the side also had a serious expression.

Pilots, as the proud sons of heaven, cannot fly fighter jets after learning the theory. They have to eat food one bite at a time and fly trainer aircraft in the same way.

After learning the basic knowledge. The pilot first flew the Chu Jiao VI, which is a propeller tandem two-seater aircraft. From the appearance, it looks like a torpedo aircraft from the World War II era. This is a Chinese imitation of the Yak 18 aircraft.

This aircraft is used to train new trainees. It is very durable and cheap. In later generations, it was only 230,000 yuan, which was not as good as a high-end car. Even Americans were interested and bought a batch from China to train their pilots. If they were placed in the United States, it would not be enough to convert RMB into U.S. dollars. The money to set up a beginner's teaching aircraft.

After flying the propeller J-6 and mastering basic aviation knowledge, the pilots began to fly the J-6. This was the transition from subsonic to supersonic speed. After all, Pakistan was equipped with a large number of J-6 fighters, so, Many pilots can fly J-6 fighters directly after getting off the J-6 aircraft.

There are only two types of training aircraft in Pakistan. Therefore, when Pakistan purchases American F-16 fighters, there are more two-seat F-16s than single-seat ones.

The training cost of using a two-seat fighter plane as a training aircraft is very high. After all, fighter jets are used for combat. The cost of flying for one hour is dozens of times that of a training aircraft.

At the beginning, China also faced the same problem after purchasing the Su-27. China's training aircraft was mainly based on the J-7. It was a trainer aircraft modified based on the J-7 and was used to train the J-7. pilot, no big problem, but Yes, if you fly directly to the Su-27 after flying the J-7, you will be in trouble. The J-7 is just a backward second-generation aircraft, while the Su-27 is a third-generation aircraft. From the J-7 to the Su-27, the span is too big. Large, resulting in complicated and wasteful pilot training.

In later generations, Pakistan was equipped with a large number of J-7 fighters, so it was necessary to introduce J-7 fighters as trainer aircraft. Now, Pakistan's main front-line fighters are already third-generation aircraft. If it is equipped with such second-generation trainer aircraft, It is definitely not a good choice, so Arslan Sr., who is in charge of the Air Force, does not intend to use training aircraft like the JJ-7.

In the past, Pakistani pilots were trained in the United States, which was included in the cost of purchasing aircraft. However, in the future, training more pilots will definitely need to be done in Pakistan itself. Especially now that we are entering the era of fly-by-wire operation, we need better training aircraft.

Muhammad heard what old Arslan said and nodded: "Yes, there can be no gap in the training of our air force talents. We must have excellent training aircraft. Arslan, what aircraft do you think is most suitable for us?"

"According to the training of Western pilots, there are three types of training aircraft, primary training aircraft, intermediate training aircraft and advanced training aircraft." Old Arslan said: "Among the primary training aircraft, we already have China's primary training aircraft 6, which is completely possible. The main ones are intermediate training aircraft and advanced training aircraft. Among the intermediate training aircraft, the US T-37 is a good choice, and it is said that China is also developing a intermediate training aircraft called J-8."

The T-37 is a twin-engine jet trainer manufactured by the American Cessna Aircraft Company. It is used to train pilots and navigators, and train students in basic skills such as driving, instrument operation, formation flying and night flying. Because it is a jet, it is not suitable for pilots who have just learned to drive to master it. It can barely be regarded as an intermediate training aircraft. This type of aircraft has been put into use since 1955, and the model is already old.

Muhammad had never heard of this aircraft, so when he heard about the J-8, his expression suddenly became excited: "Yes, it's the J-8, this is a good trainer aircraft!"

Mhammad, who came from the future, of course, has heard of the name of this trainer aircraft. In China, this trainer aircraft can be said to be one of the few star products. It is not only equipped with the Chinese Air Force, but also exported to many countries. Of course, many people may not have heard of the name J-8, but K-8 is definitely heard of.

It was originally a trainer aircraft, and it did not start with J, but K, because the letter K is the Karakorum Mountains at the junction of China and Pakistan. This aircraft, in history, was a trainer aircraft jointly developed with Pakistan!

The Nanchang Aircraft Manufacturing Company in Jiangxi is famous for producing trainer aircraft. The J-6 comes from this company, and the Q-5 is also the representative work of this company. Afterwards, watching the constant upgrading of fighter planes in the world, we realized that trainer planes also needed to be improved. Therefore, in 1982, a trainer plane program group was established, with Shi Ping as the leader of the program group and later as the main designer. Through market research, the development idea of ​​"improving training efficiency and reducing training costs" was determined, with basic performance requirements and two training systems that meet the needs of different countries. Moreover, it is necessary to take into account both high and low speeds; have good maneuverability and stall characteristics; good vision and comfortable cockpit environment, etc.

After all, this kind of trainer plane is not a national project, but is completely developed by the company itself. This kind of trainer plane needs to enter the international market. Therefore, the goal is very high.

However, the initial development was not smooth. Until 1986, Pakistan joined in and assumed a quarter of the investment, while producing part of the fuselage.

In this way, the J-8 has become an international cooperation project. The initial equipment target was the Pakistan Air Force. Many of the equipment selected are also from the West, such as Martin-Baker's zero-zero ejection seat, Western electronic flight instrument system, instrument landing system, TACAN navigation system and radio, etc., mature products in the international aviation market. In cooperation with the American Aerospace Equipment Company, an efficient environmental control system was installed, and in cooperation with the American Garrett Company, the intake and exhaust system was designed. Pakistan's participation made the development of the J-8 fast and smooth, solved the problem of serious shortage of military scientific research funds, and improved the aircraft. It has become an advanced aircraft developed by international cooperation.

In history, in 1987, the J-8 began to be specifically designed. In January 1989, the prototype was manufactured, and the first flight began in 1990. After the finalization, it was first equipped with the Pakistan Air Force, and the domestic self-use model was not finalized until 1998. At this time, Nanchang Aircraft Manufacturing Company has also become Hongdu Aviation Industry Group.

However, these are all historical things. Now, after Muhammad took control of Pakistan, Pakistan did not cooperate with China to develop this kind of trainer aircraft, but directly aimed at fighters. Reverse mapping Tomcat and understanding each subsystem are Pakistan's main goals. Now, this imitation Tomcat fighter has already started its test flight, while the J-8 in Jiangxi is still an independent project. I wonder how the development progress is? (To be continued ~^~)
