Next generation aircraft!

Now, China has just successfully developed the third-generation fighter jet, namely the J-10 fighter jet. At this time, the West has been equipped with the third-generation aircraft for nearly twenty years, and the next-generation fighter jet in the West is about to end the competition for prototypes, and Lockheed wins.

Therefore, although Cheng Fei had just successfully developed the third-generation fighter jet, Mr. Song planned to hand over the subsequent improvements to young people, and he himself developed the next-generation fighter jet.

In later generations, this fighter jet was the black ribbon in the eyes of military fans. It was developed by Mr. Song and a large number of technicians after the No. 10 aircraft were just formed and worked hard.

But now, history is still surprisingly similar, but the progress has been ahead of schedule by nearly ten years.

After hearing Mr. Song’s pre-research for the next-generation aircraft, Mhamad immediately showed great concern: “Is that so? What are the technical indicators of your next-generation fighter jet?”

Because it was more than ten years ahead of schedule, the world's largest F22 fighter jet in later generations had not yet tested it at this time, and everything was on paper. Although the Americans put forward various technical requirements for the aircraft, they needed to be carefully distinguished. After all, some of them fooled the Soviet Union.

"Low detectability, excellent maneuverability, dual-engine heavy-duty air control," said Mr. Song.

The United States has decrypted the f-117, and everyone around the world knows that the Americans have an advanced low-detection aircraft. Although it is an aircraft of the size of an F-16, the radar reflects only the size of a helmet. Therefore, this low detectability is very critical. It is obvious that the enemy's radar will find that the distance of this aircraft will be greatly shortened, and the safety of this aircraft will be higher, which also means that it can attack the enemy's aircraft.

For our next-generation fighter jets, it is obviously necessary to have low detectability! This requires redesigning the appearance, which must have good maneuverability and greatly reduce the radar reflection area. This is almost a contradiction and more difficulties need to be overcome.

Mobility has always been the goal pursued by the Chinese Air Force. All Chinese aircraft, J-6 and J-7, are known for their maneuverability. For example, the improved J-7 can catch up with the F-16 in close combat capabilities.

If you want to have excellent maneuverability, you need to have strong power, so this new type of fighter must be a dual-engine.

Mhamad listened to the other party's statement and these were all good, but there was still something missing.

"The technical performance of the next generation of fighter jets was proposed by the United States. In addition to these, there is another important aspect." Mhamad said: "It is supersonic cruise!"

Supersonic cruise! If an ordinary fighter wants to fly supersonic, he must turn on the afterburner and the afterburner. To put it bluntly, it means injecting more fuel into the combustion chamber of the aircraft engine to accelerate the combustion and obtain greater thrust. This method is very simple and the effect is obvious. However, one sequelae is that the fuel consumption is too great! Ordinary flight can fly for one hour. Once the afterburner is turned on, it will not be used for ten minutes, and it will be consumed.

Therefore, although the fighter can fly to Mach 2 in performance indicators, a plane only has a very small time to fly supersonic during its full life, and most of it is subsonic.

In later generations, once the American F-22 entered supersonic cruise while fighting other fighters, the air battle was declared to be over because other aircraft could not keep up with the F-22 at all. Even if they chased after them, they would be out of fuel in a few minutes.

Therefore, supersonic cruise seems to sound nothing, but in actual combat, this ability is more important. Moreover, supersonic cruise means that you can quickly reach the war zone during interception missions and quickly evacuate after completing the mission.

Hearing Mhamad's words, Mr. Song had a hint of embarrassment on his face. He scratched his bald head and said, "We have discussed this indicator before, but we found that it is too difficult for us to achieve this indicator."

It is indeed too difficult. Later America could create a supersonic cruise of Mach 1.6 without force-opening. This is achieved by relying on the abnormal technology of the United States and general alien technology. Without a high thrust-to-weight ratio engine, it is impossible to conduct supersonic cruise in this fighter with conventional aerodynamic layout.

For Huaxia, the engine is the biggest constraint. The No. 10 engine can go through the complete process. Thanks to the TF41 engine, this is a large-thrust engine that Huaxia can produce in large quantities. When the f110 is replaced, the maneuverability immediately reaches a new level. Unfortunately, this engine is too expensive, and Pakistan's production capacity is limited, which is mainly for Pakistan's own air force, so it cannot be equipped with Huaxia on a large scale.

Based on the existing technology, improving and increasing pushing based on TF41 will not meet the needs of supersonic cruise. Therefore, it is also imperative that this indicator be cut.

"If the engine is not powerful enough, it must be retrieved from the aerodynamic appearance." Mhamad said: "It is actually not very difficult to achieve the goal of supersonic cruise based on the existing technology."

If the engine is not strong, it can only be compensated by aerodynamics. The J-10, which is a duck-type layout, is the product of this idea. No American aircraft has a duck-type layout because their engine performance is excellent enough. Even Western Europe has adopted a duck-type layout without exception because of the engine defects.

Mr. Song nodded. It was indeed the case. He thought so too. Therefore, the development of new fighter jets is based on the existing duck-style layout plan. After so many years of development, this layout has been thoroughly understood by Cheng Fei. However, the duck-style layout, without a large thrust engine, will not be able to achieve supersonic cruise.

Thinking of this, President Song suddenly woke up: "President Mhamad, are you talking about other aerodynamic layouts?"

"Yes, as long as the resistance is reduced, it will be easier to enter supersonic cruise." Mhamad said: "What do you think?"

"You mean variable swept wings?" Mr. Song understood completely.

The variable sweep wing will allow the fighter to have excellent aerodynamic performance in all states, which can not only fight in close range and sprint quickly. Now the Tomcat fighter equipped by Pakistan is such an advanced fighter.

After replacing the F110 engine, the maneuverability of the Tomcat fighter has increased significantly. Mhamad knew that when the US Navy began to propose the Natf, that is, the Navy's advanced tactical fighter plan, Grumman immediately made a bidding plan. The code-named Tomcat 21 is actually a major improvement model of the F-14. It uses a large amount of composite materials to reduce radar reflected signals and weight, and also enhances ground attack capabilities. Moreover, it is planned to install the F110-ge-129 high-bypass ratio turbofan engine to reduce fuel consumption and improve range. After calculations, Grumman proves that this fighter can have supersonic cruise capabilities.

As long as you understand all the technologies of the f110 engines currently produced by Pakistan, further increase thrust, and improve to the level of f110-ge-129, the Tomcat fighter can have supersonic cruise capabilities! Not to mention the disintegration of the Soviet Union in a few years. If the Soviet al-41 engine can be obtained, it will have better supersonic cruise performance.

In addition to increasing the thrust of the engine, the weight of the aircraft can be effectively reduced with the large area of ​​composite materials. At the same time, all weapons are built-in and can also reduce drag. Therefore, it is completely possible to develop a fighter that meets the characteristics of the fourth generation aircraft based on Tomcats.

After listening to Mhamad's explanation, Mr. Song slowly shone brightly in his eyes. He knew that theoretically, using variable sweep wings can more effectively obtain the ability to cruise supersonic more effectively!

In later generations, Cheng Fei encountered the biggest problem when he developed the J-20, which was because of the lack of a qualified engine, which led to a beautiful appearance. The fighter called the black ribbon by netizens did not have supersonic cruise capabilities. The engine it used was still the al-31 engine used on the Su-27. It lacked power and could not perform supersonic cruise.

Mr. Song led the research and development personnel and had already begun to explore hard. The main solution now is still a duck-like layout. Now, when I heard Mhamad's words, would they want them to give up their existing technology and adopt variable swept wings?

This change is too big, almost like starting over, and the challenge faced is also the biggest.

"We have started the pre-research of the modified Tomcat in China." Mhamad did not hide his own progress. After all, although Pakistan has had high scientific research capabilities after years of hard work, it is still difficult to develop a qualified fourth-generation aircraft. Working with Chinese technicians to develop new fighter jets can not only reduce investment, reduce technical risks, but also make up for technical shortcomings both sides. Moreover, after the development is successful, the two countries can jointly equip and reduce development costs. This is very suitable for both sides.

So, after hearing that the other party was developing the fourth-generation aircraft, Mhamad immediately made a decision to develop his fourth-generation aircraft with China!

Nowadays, joint development of military aircraft has become a trend. After all, it is expensive to develop advanced modern fighter jets. European countries have taken the approach of development, such as the Qianfeng fighter jets and later European fighter jets, all of which are all thinking.

Pakistan has conducted in-depth research on aerodynamic appearance and has sufficient stealth ability. However, engine research and boosting is not that simple. The United States is now quite vigilant about Pakistan, and it is absolutely impossible to output more advanced engines to Pakistan.

Only by bringing the Chinese personnel together can we speed up the progress.

After Mhamad finished speaking, the entire conference room fell into silence, and the second hand was ticking. Mr. Song thought quickly in his mind that these four generations of machines were originally the most confidential project for the future of the motherland. However, if it took a long time to work with Pakistan, it would greatly speed up the progress. The two sides had already cooperated a lot before. However, the plan proposed by Pakistan is variable sweep wing, which is an improved plan from Tomcat. Do we want to push down our plan?

Mhamad is also sitting quietly. If China disagrees, Pakistan will develop itself. Now, with the continuous advancement of aviation technology, the integration of large edge strips and wing bodies, these technologies are becoming more and more developed, while variable sweep wings have not been launched. Therefore, there has always been a voice in the aviation industry that variable sweep wings are outdated!

Is it outdated? In later generations, the retirement of the American Tomcat represents the end of this classic variable sweep-wing fighter. However, that is because the United States has fought invincible all over the world. If the Soviet Union still exists, the United States will never eliminate this advanced fighter. No matter how advanced the Bumblebee is, it does not have the long-range interception ability of the Tomcat fighter to carry six Immortal birds.
