More than 200 aircraft, Mhammad is not boasting, after all, in later generations, Egypt purchased a full 100 aircraft, and also exported the production line, which is a huge progress for the Chinese aviation industry!

Now, the relationship between Pakistan and Saudi Arabia is not bad, the two sides have the same faith, and Osama is in contact with it, with the growth of Pakistan, it will enhance its influence in the Middle East, and when the time comes, Saudi Arabia and other countries will definitely be equipped with this kind of training aircraft, so the market prospect is very large.

What Mhammad needs is not just to import this engine, but it is best to introduce a production license and produce it, after all, this small turbofan engine can also be used in many aspects, for example, in the future, the higher education aircraft can be in the form of twin engines, and what kind of business jets and other aircraft need such turbofan engines.

Even, future cruise missiles will also need a small turbofan engine, although the size of this engine is relatively large, but it still has a reference role for designers.

Mhammad hopes to take advantage of the current honeymoon period with the United States to get his hands on the technology of this small engine, but if it is really not possible, then he will also introduce a batch and equip this kind of training aircraft.

With its current relationship with the United States, Pakistan can still get those engines.

If the Air Force wants to have strong combat effectiveness, the training system must be complete, and with the attention of Mhammad, Pakistan's main training aircraft has also entered a new period of upgrading.

Sure enough, the negotiations went smoothly, and in the negotiations in Pakistan, the Nanchang company was led by the deputy chief engineer to the United States and signed a technical agreement and a business contract with Garrett Company. The contract stipulates that during the development phase, Garrett will provide 3 engines and related accessories free of charge. A starter generator, hydraulic pump, and environmental control system are recommended for use with the engine, and engine thrust test tools are provided free of charge during the flight test phase of the aircraft.

At the same time, the Jiao-8 has become an international cooperation project, and the first object of this training aircraft is not the Huaxia Air Force, but the Pakistan Air Force.

Aviation technology. It is the technology that can best reflect a country's high-tech level, and whether or not it can manufacture advanced third-generation aircraft is an important embodiment of a country's scientific and technological level.

At the end of the year, the cold Chengdu also ushered in the most exciting day.

The aircraft designers of the 611 Institute have been waiting for this day for a long time.

At this time, on the runway, a strangely shaped plane. Final preparations are being made before takeoff.

From the establishment of the project to the end of the overall design of the first aircraft, until now, the prototype has been built and the test flight has begun, and the progress of the successful flight is quite fast, all thanks to the availability of ready-made engines.

In the Hereafter. The development of such an aircraft has gone through a long and tortuous process. The main reason is that the supporting engine is not up to standard, the engine progress is far behind the development of the fuselage, and it cannot be installed and used at all, and later, due to the introduction of Su-27 fighters in China. It was decided to use the engines of such fighters to equip Project Ten, as a result of which the rear fuselage was almost redesigned.

Now, it's completely different, thanks to the help of the Pakistani side. On the basis of eating Spey, there is already a mature engine like TF-41 that can be used, so, after the national project is established, the development progress of the fighter has been very fast, the main avionics, the difficulties of the engine have been overcome, only the fuselage remains, the fuselage has been studied repeatedly since the aborted J-9, and the technology has long been thoroughly understood, and the final telex has also matured.

It's just that the prototype of Project 10 on the runway at this time is still different from the famous J-10 fighter in later generations. The biggest difference is the front fuselage.

The nose of the aircraft is not round, the lower part is slightly flattened, and under the belly, it is not an adjustable air intake with an inclined plate, and there are no additional six sticks that were added when the aerodynamic problems were found during the test flight. In this respect, it looks more like Israel's Cub fighter.

The aerodynamic layout of this design, of course, is to copy the Pakistani F-16 fighter to the greatest extent, when the F-16 fighter was obtained in Pakistan, it was once surveyed and mapped by aircraft experts in China, the nose of this kind of aircraft, the air intake can be pre-compressed, and the use of fixed air intake, the structure is simplified to the greatest extent, and the weight of the aircraft is reduced.

However, the design of such an air intake is also flawed, for example, this fixed air intake will greatly reduce the supersonic performance, similar to the F-16, although theoretically able to fly to Mach 2, but in fact, only to fly to Mach 1.6, it is already inadequate.

The reason for this design, in addition to copying the design of the F-16, so that the fighter can be quickly trial-produced, on the other hand, is the new air intake, which has begun to blow the wind tunnel, this kind of air intake, is the kind of DSI air intake invented by Pakistan! Using a fixed structure, the air is pre-compressed through the envoy's bulge to achieve good air intake efficiency in all conditions.

Now, this air inlet model is definitely the first in Pakistan, and Huaxia naturally took a full set, and found that the theory is okay, but in fact there are many imperfections, and they need to keep blowing the wind tunnel to find out the best configuration.

Therefore, the current air intake is only used improvised, and after the development of this new air intake is completed, maybe the new air intake can be used for subsequent test flight models.

Of course, there is another aspect, that is, Pakistan's Tomcat fighter, which has been flying for half a year, if nothing else, within two years, it should be able to finalize and equip the Pakistan Air Force.

At the same time, the Chinese side can also start to manufacture this advanced variable sweep wing fighter at the same time, when the No. 10 project was just established, it was designed according to the air superiority fighter, aiming at the Su-27 and MiG-29 and other advanced fighters of the Soviets in the north. And now, Huaxia can already obtain excellent heavy air supremacy fighters, and the task of the No. 10 machine has changed from seizing air supremacy to a multi-functional fighter, so the requirements for speed are not as urgent as they were at the beginning, just like the low-end aircraft in the high-low and high-low combination of the F-15 and F-16 in the United States, which need to be cheap and can be reequipped in large quantities.

At this time, the chief designer of the aircraft, Mr. Song, who was almost sixty years old at this time, stood here, looking at the plane, his heart was full of excitement.

"Yang Wei, are you confident?" Mr. Song said to Yang Wei, the flight control designer next to him.

This plane, there is no mechanical backup at all, in case the telex system fails, it will be troublesome.

"Mr. Song, please rest assured, we have carried out many tests on the Iron Bird, and also carried out perfect tests on the Tomcat fighter in Pakistan, all the components of the fly-by-wire system can meet the needs of reliability, and the software has been completely optimized, I believe that you will not be disappointed." Yang Wei said confidently.

After staying in Pakistan for a while, the Pakistani newly-built Tomcat fighter was very perfect in terms of fly-by-wire control, which also gave Yang Wei a lot of confidence, and he believed that his aircraft would never fail in the flight control.

"Okay, then I'll be relieved." Mr. Song said, unconsciously, he felt his hands seem to be trembling slightly.

This aircraft is just the beginning, and when this aircraft completes the test flight, he will lead the scientific researchers to continue the development of the next model, and at this time it is still a more confidential project, that is, a stealth aircraft!

"Hadron, how do you feel?" In the eyes of everyone, test pilot Lei Qiang walked to the plane, he was wearing an orange anti-load suit, and his face was flushed.

Seeing him like this, the political commissar of the test flight team couldn't help asking, "Do you want to measure your blood pressure?" ”

Lei Qiang shook his head and continued to walk forward, the political commissar grabbed his hand and found that his pulse at this time was beating rapidly, almost 150!

Lei Qiang continued to walk forward, went up the gangway, and entered the cockpit, and when the hatch was closed, he saw the political commissar below, with tears in his eyes.

Anyway, this is, after all, the first brand new fighter in China! The aerodynamic layout of the previous fighters is different, and it is controlled by fly-by-wire! If something goes wrong, you might not be able to come back!

Even if you die, you have to fly the plane back! When he opened all kinds of electric doors and made preparations before takeoff, Lei Qiang's brain immediately sobered up. They have been waiting for this day for a long time!

There was a roar of the engine from behind, the mature TF-41 engine had started, and Lei Qiang's voice became calm: "001 requests to take off!" ”

After receiving the order from the tower, Lei Qiang released the brakes, and the fighter quickly slid on the runway.

After only flying 400 meters, Lei Qiang gently pulled the operating lever backwards, the front landing gear left the ground, the nose of the aircraft was raised, and it followed, and it flew for another second, and the main landing gear followed and got up.

This is an agile fighter! With the canard layout, the positive lift is obtained, the instantaneous pointing ability of the nose is very high, and the take-off is quite crisp and neat! The J-7 needs a runway of more than 1,000 meters to be able to take off, and now, in less than 500 meters, this plane has already risen! If you turn on the afterburner, maybe you can make it fly on a runway of more than 300 meters!

There was jubilation on the ground, and the number 10 machine finally flew up! (To be continued......)
