Mr. Song's statement determined the tone of the two sides and jointly developed it! It's good for both sides.

"Okay, we're going to go through careful arguments, and if your plan is better, we can accept the canard layout." Mhammad said.

The fourth-generation aircraft is a big project, and it must be rigorously demonstrated, and now, Pakistan is developing the fourth-generation aircraft, but it can only be called pre-research, and although Mhammad appreciates the various advantages brought by the variable sweep wing, if it is proved that the canard layout is more suitable after demonstration, Mhammad will also accept this layout, after all, even the new aircraft of the Soviet Union, the MiG-1.44, adopts a canard layout.

On the first day he came to China, Mhammad and Huaxia's Chengfei reached a major agreement, a fourth-generation aircraft, which is a major piece of equipment related to air warfare in the next few decades, and the cooperation between Pakistan and Huaxia in this regard will further deepen the cooperative relationship between the two countries.

After ending this topic, Muhammad was very excited, looking at Bai Xue who was sitting opposite him, Bai Xue was still an expert in Huaxia, and he was also qualified to attend the meeting this time. And next to the snow, there is Tu Jida.

Mr. Song is mainly responsible for the development of new models, while Tu Jida is to exert residual heat.

Feeling that Mhammad's gaze was looking at this side, Tu Jida's heart was hot, and he said: "We are still raising our own funds to develop a new foreign trade model, I wonder if Pakistan is interested in cooperating?" ”

Self-funded! With the successful development of the No. 10 machine, Chengfei has accumulated rich experience in research and development, and Chengfei's flagship product over the years, that is, the J-7, has been sold to many countries in the third world, therefore. Chengfei also hopes to launch a replacement model in time.

Hearing Tu Jida's words, Muhamad was also stunned, could it be that Tu Jida was talking about the Thunder Dragon?

Historically, Pakistan was unable to obtain advanced fighters due to sanctions imposed by the United States, and could only develop the Thunder Dragon fighter together with Cheng Fei. When Xiaolong joined the Pakistan Air Force, the chief of the General Staff of the Pakistani Air Force was so excited that he cried, and finally had new equipment to protect Pakistan's airspace!

And now, history has taken a big turn, Pakistan already has a South Asian, even world-class air force, naturally there is no need for low-end models like the Thunder.

Although Pakistan does not need it, but. Many countries in the third world still have demand, they also need third-generation aircraft, but their funds are insufficient, so another affordable third-generation aircraft must be launched, which will definitely be able to occupy their market!

Chengfei has undergone self-unloading research. It was decided to start in this area, and Tu Jida was the chief designer of this model.

This new model. Now, the tide of market economy has swept the whole land, and Cheng Fei raised his own funds and developed it himself. Promote it yourself, and the income is also flying.

"Tell me about it?" Mhammad asked.

Although Mhammad is the president of Pakistan and has never attended an aviation academy, he is very knowledgeable. When they were still at the Peshawar base, Mr. Song, Mr. Tu and others went to Pakistan and were impressed by Mhammad's outstanding insight. And now, Mhammad is interested, which makes Tujida very excited.

"Our model, codenamed Super Seven, plans to take the same two sides of the air intake as the J-8II fighter on the basis of the J-7 fighter, and the leading edge flap of the wing root has been increased, and a new turbofan engine has been replaced at the same time, so that the combat effectiveness of this fighter can be greatly improved, especially the position of the nose is left, and a large-caliber radar can be installed, which can have over-the-horizon air combat capabilities." Tu Jida said.

In the Soviet Union, the MiG-21 was just a transitional model, and the Soviet Union did not regard the MiG-21 as a key model, but in China, the J-7 copied by the MiG-21 can be regarded as a meritorious model and has been in production for decades.

Huaxia has almost thoroughly eaten all the technology of the J-7, so, on the basis of the J-7, change the nose, become the air intake on both sides, replace it with a new engine, and become a new model with little technical difficulty, which is the project under the leadership of Tu Jida at this time, with little investment and quick results, and the first flight can be made in one year at the earliest.

Hearing Tu Jida's words, Mhammad couldn't help but shake his head: "No, this kind of improvement is too backward. The air intake on both sides is not suitable, and when steering at high speeds, the air intake on one side will be blocked, reducing the intake efficiency and not conducive to flying at high angles of attack. To free up space in the nose, it is most suitable to take in the belly. However, the belly air intake is easy to suck in foreign bodies, and our base does not matter, but if it is exported to the third world, their runway will definitely not be clean, and if the engine is broken, it will be said that our aircraft is too bad, and it is necessary to take into account both reliability and excellent air intake efficiency, and the two-rib air intake is the most suitable. ”

Listening to Mahmad's words, Bai Xue's eyes lit up, and Mahmad's profound knowledge was simply too admirable, and in a few words, he explained the advantages and disadvantages of various air intakes, and also put forward a suitable plan, this man, all over his body, exudes a unique charm, attracting Bai Xue.

Tu Jida also nodded: "Yes, the air intake on both sides is the scheme of the second-generation aircraft, and the third-generation aircraft rarely uses the air intake on both sides." ”

In fact, Mhammad's knowledge comes entirely from the understanding of later generations, but he knows that what was finally created at the beginning, the crystallization of Sino-Pakistani friendship, and the aerodynamic shape of the Thunder Dragon is the most suitable.

"The use of the J-7 fuselage is not suitable, after all, it is the MiG-21, no matter how it is improved, it is difficult to have a more progressive performance, now, the large side wing has begun to become popular, the use of the wing wing with the edge of the wing, plus the wing body fusion, just like the F-16 model we are using in Pakistan now, I think it is more suitable." Mhammad said.

Although it is a low-cost aircraft, it must also have an excellent aerodynamic layout, and F-16 as a classic third-generation aircraft, aerodynamic is still good, Huaxia has also carried out a full range of mapping of F-16, Mhammad put forward the point of view, is based on the F-16 airfoil, side wing and other similar structure.

The function of the edge wing is to produce vortex, and the vortex is a special airflow, which can greatly improve the lift of the wing and improve the flight performance at high angles of attack.

In fact, the later generations of Thunder Dragons are not very related to the F-16, but now that it is being redeveloped, it is also a very good choice to use the F-16 as a reference.

"As for the engine, you should be planning to use Spey engines, right?" Mhammad continued.

Tu Jida nodded, if it weren't for the fact that the other party was the president, Tu Jida really suspected that the other party had stolen his own research information.

It is not unusual for Mhammad to guess this, after all, for Huaxia, the only mature one now, even if it is the Spey engine, the use of Spey's additional model, that is, TF41 to equip the J-10, and the use of the prototype to equip this foreign trade aircraft, is a pretty good choice, after all, the later generations of Thunder Dragon, using the Soviet Union's RD93 engine, the middle thrust is less than 50 kN, and the afterburner thrust is just 80 kN, which is about the same as Spey's parameters.

"President Mhammad, your knowledge is a shame for us technicians." "The plans you put forward are certainly much better than our previous plans, but the risks of such technology will be greater, and the investment we need will far exceed expectations," Tu Jida said. I'm afraid it won't be finalized anytime soon. ”

"Yes, such a technical difficulty is much more difficult than the aircraft modified on the basis of the J-7, but the advantages in performance are also obvious, the third world countries we are aiming at need a cheap aircraft, but if the performance is too scummy, I am afraid that they will not get the order, they would rather be less equipped, and they will also hope to have an aircraft with sufficient technical performance, only modified on the J-7, it is not enough to meet the needs." "Our Super Seven must be at least 70 percent of the F-16 before it can open the market," Mhammad said. ”

After speaking, Muhammad paused: "Now is a new era, the era of winning by quantity no longer exists, the quality advantage is more important, our foreign trade aircraft, but also have a performance level to attract enough customers." As for the investment side, we are willing to put half of the capital into it. ”

Half the funds! Pakistan will share half of the cost of development! It was originally self-funded, and the budget of the project was limited, so it would propose an improvement project on the basis of the J-7, and if Pakistan provided half of the development cost, the new model could also be considered!

Tu Jida nodded: "If this is the case, we can sign the contract now, and we can reconsider and design a fighter with more advanced performance according to your requirements." ”

Now, Chengfei's project is full of arrangements, with follow-up modifications of the J-10, new fourth-generation aircraft, and foreign trade aircraft, and unconsciously, Chengfei has become the largest cradle of fighters in China.

Mhammad looked at the people present, suddenly remembered something, and said: "By the way, didn't the Soviet Union want to provide Su-27 fighters at the beginning?" How's the project going? ”

Shen Fei has no new projects, the tinkered air beauty man, the main focus is still high-altitude and high-speed, the Su-27 was introduced at the beginning, but Shen Fei and a group of guys from the Third Aircraft Department highly recommended.

It has nothing to do with Mhammad, as long as Shen Fei's project will not squeeze out Cheng Fei's project, Mhammad asked this purely out of curiosity. (To be continued......)
