In later generations, Shen Fei has been engaged in it for so long, and the propaganda is very good, but in fact, the J-11 and J-15 still use the original analog telex, and there is no digital telex at all.

Cheng Fei has been using his own strength to develop digital telex, which has become a huge progress.

Now, the imitation of the tomcat, if Xifei's power can't do it, then you can contact Cheng Fei and solve it together, in short, Mhammad is unwilling to deal with Shen Fei.

"Yes, it seems that the burden of Xifei and Chengfei has to be heavier." Deng Gong said: "I really want to go to Chengfei immediately to see how our No. 10 project is going." ”

Cheng Fei also undertook the country's key projects, and when Shen Fei was still tinkering with the J-8 2, Cheng Fei had already begun to develop the third-generation fighter.

In later generations, this kind of fighter is still progressing slowly, especially in the case of the lack of engines, in the nineties, after the Su-27 was equipped with the domestic market, the AL-31F engine was used, so that the test flight work was carried out, from the 84 years of the project, until the first flight in 02, this project, carried out for 20 years! And when this kind of fighter is equipped with the troops, the fourth-generation aircraft of the United States has also entered service with the troops, and after the Jian-10 began to enter service, Chengfei immediately began the development of the next project.

And now, due to the influence of the Pakistani side, such fighters are highly valued by the central government.

An exercise conducted by Mhammad in the country has made those high-ranking military officials see what modern air warfare is, and that the method of relying on long-range air-to-air missiles under the command of early warning aircraft will become the main way in the future, and the bayonet fighting in the air has become outdated. Equipment became an important factor in the war!

Project No. 10 is of great significance, and now, relying on its good relations with the West, Chengfei can obtain some Western equipment and technology to speed up the development of fighters.

Now, it is the third year of the development of Project 10.

The J-10 of later generations. The main lack is the advanced radar and fire control system, and the other is the engine, among which, the engine is the most critical, after all, it is the crown of the aviation industry, which has been developed domestically for so many years. There have been many models, but none of them were finally put into use, which shows the difficulty of Cheng dù.

And now, both of these problems have been solved, with the independent efforts of Cheng Fei, and there are AWG-9, APG-66. APG-71, these advanced radars are intended to be imitated by the fly. They have completely broken through the technical barriers, developed their own advanced planar slot radar, and only need to replace the imported foreign civilian parts with the parts designed and manufactured by themselves that meet military standards.

And another, the engine project, also has a choice. It's the TF-41 engine. The performance is stable, the fuel consumption rate is low, and the maximum afterburner thrust reaches 11000 N. It is completely possible to promote the project machine of Project 10.

The final task left to Cheng Fei is the development of the airframe, from the early J-9 project, Cheng Fei began to constantly contact the duck layout, the aerodynamic aspect has been thoroughly understood, and with the full support of the state, the project is progressing rapidly.

At that time, because of the competition with Shen Fei for the project, it was carried out for several years, and after that, continuous improvement and research were started. Chengfei chose the engine turbojet 15, but until the early 90s, the turbojet 15 was still in the trial production of components, the official finalization was far away, the engine was not, and the project was probably scrapped again, at this time, the Air Force planned to introduce the first batch of Su-27 from Russia, so General Zhang Aiping, then Minister of National Defense, proposed that since he bought the Su-27, he would simply buy more AL31F engines and replace the J-10.

In order to make progress in J-10, so, in 92 years, Song Wencong as a plenipotentiary representative, went to Russia to negotiate the introduction of AL31F, in order to adapt to J-10, AL31F made a number of improvements, such as changing the receiver accessories to the bottom, etc., the improved model is called AL31FN, since then, J-10 has a new heart.

However, in order to adapt to the new AL31FN, the J-10 was almost pushed to the ground. The original design of the simple non-adjustable elliptical air intake can no longer meet the needs, and the high-altitude performance of the turbofan engine is far inferior to the turbojet, so it has been improved to a rectangular adjustable air intake to ensure flight performance at various altitudes and speeds; Since the AL31FN is much longer than the turbojet 15, the rear fuselage needs to be extended, the center of gravity of the whole aircraft needs to be retrimmed and adjusted, and the chord length of the main wing wing is also greatly increased, as a result, the progress of the first ten years is almost in vain.

And now, the development of the J-10 has not taken any detours, the TF-41 engine has been determined, the biggest problem has been solved, plus the many experiences accumulated by Chengfei in the J-9 project, after three years of design, all the design work has begun to freeze, and the first all-metal prototype has been built.

When Mahmad and Deng Gong entered Chengfei, the first thing they did was to go and see the all-metal prototype.

The prototype is a prototype of a fighter before it is officially manufactured, in order to reduce some possible problems, such as assembly, etc., some of the components may still be under development, and will be replaced by wooden blocks, although it is only a prototype, many problems can also be found.

Mhammad looked at the prototype in front of him, with medium-range coupling and a large area of canards, which is a typical aerodynamic layout of a third-generation and a half-generation fighter, and Cheng Fei has accumulated a lot of experience in this regard.

The bubble-shaped cockpit, with an integrated windshield in front, belly air intake, and rectangular air intake, did not have those stiffeners at this time, and later generations won the title of stick because of these stiffeners.

Mhammad's interest was quite high, when he sat in the prototype, he saw the dashboard in front, or mainly mechanical instruments, dense instruments, which made people feel uncomfortable at a glance, and Mhammad couldn't help but shake his head.

"Mr. Song, why don't you use a glass cockpit?" Mhammad asked Chief Engineer Song Wencong.

In this era, the glass cockpit has not yet risen, such as the F-14, which is almost all instrumental, and the F-16A equipped by Pakistan, due to the later development era, has begun to adopt the layout of "one flat and two down". The head-up display is smaller in size and also has a video recorder in the middle. There is a large LCD display on the left side to display the plug-in information, and in the middle is the radar screen or the cathode ray tube. In the middle and right of the dashboard are a large number of traditional gauges. Includes speedometer, horizon meter, angle of attack indicator, level indicator, and more. Although there is still a big difference between this level and the display interface that is almost all large LCD screens in later generations, after all, it is already a trend.

In later generations, when the J-10 first flew, there was already an LCD monitor, but after all, it was already 98 years, and now, it is only 86 years, Chengfei did not dare to be so advanced, using LCD monitors to replace traditional instruments.

Hearing Mahmad's question, Song Wencong smiled bitterly: "Our current LCD monitor is not very clear in strong light, and in battle, once the sunlight shines into the cockpit, it may make the display ineffective."

In the early 80s, there was already monochrome TN-LCD, which was mainly used in medical equipment and computer output equipment. However, the performance of such a display is not ideal. It wasn't until a few years later, when STN-LCD display technology was mastered, that liquid crystal displays began to spread widely.

When Muhammad heard Song Wencong's words, he immediately understood, after all, this is not the era when LCD displays were so popular in later generations, but he still has a way.

"We in Pakistan, which are about to produce the latest LCD displays, can fully meet the requirements." Mhammad said.

Toshiba has a lot of good things, in addition to those mechanical equipment, Mhammad also introduced some electronic industries, including the production line of this liquid crystal display.

"That's really good, it can make our cockpit more concise, our fighter is aimed at the advanced fighters of the West, and the ergonomics cannot be backward than the West." Song Wencong said.

Now Cheng Fei is full of confidence and wants to get this kind of fighter out.

Deng Gong also looked at this fighter with great interest, the appearance is very beautiful, a beautiful fighter is the symbol of an advanced fighter!

After inspecting the prototype, in the office, the meeting also started in a friendly atmosphere.

Song Wencong first reported to Deng Gong the progress of the development of the fighter, including that all the design work has been completed, and after the completion of this prototype, it is ready to start production of the initial fighter, the first one will be used as a static force, the second, and the third will carry out test flight work.

After listening to Song Wencong's report, Deng Gong nodded and made a few instructions, we must be objective, act according to scientific laws, and do not make subjective mistakes.

This is the top secret of the state, and the secrecy work of the Jian-10 back then was done quite well, and foreign countries did not know the existence of such a fighter at all, even now, it is the same, but it is open to Pakistan.

After all, this fighter has developed rapidly with the help of Pakistan, without Pakistan, there would be no avionics and engine research and development, without these, the J-10 will take a lot of detours.

Even in the development of the J-10, some Pakistani engineers participated.

"What we are most concerned about is the flight control, the No. 10 project uses three-axis four-redundancy digital fly, now, how is the development of the flight control?" When the debriefing was over, Mhammad asked. (To be continued......)
