To say that in this year, the most interesting thing about Huaxia's military equipment is the introduction of American-made F-16 fighters, and the Americans have offered very preferential conditions, which can export the production line to Huaxia, so that Huaxia can independently produce such a fighter, and there are no political additional conditions!

If Huaxia seizes this opportunity, it can upgrade its own military aircraft manufacturing, until now, Huaxia's military aircraft, or the old foundation of the MiG-21 in the sixties, can finally be upgraded to advanced third-generation fighters!

Shen Fei of Huaxia is very enthusiastic about this project, after all, the production of this fighter is to be placed in Shen Fei, and they have vacated several factories in advance, ready to upgrade their own processing equipment to produce this advanced fighter!

Now, the project is still being negotiated, Shen Fei is up and down, in high spirits, ready to produce American-made fighters, and at this time, a document from the General Staff has also arrived.

Ten days later, the F-16 fighter and Cheng Fei's No. 10 aircraft conducted a confrontation exercise! Drill subjects, from medium-range air combat, all the way to close-range combat, both sides are fighting in unknown airspace!

Shen Fei's leaders were very dismissive of this document, Cheng Fei's No. 10 machine? It's nice to be able to fly now, combat effectiveness? Do you think that the aircraft will have combat effectiveness when it is built? It is necessary to successfully finalize the test flight and equip the troops after several years of test flights, and then carry out modification training. Cheng Fei wants to enlarge the satellite? Then let them come!

Defeat Cheng Fei with dignity and let them know who is the eldest son of the republic!

However, the only thing that worries Shen Fei is the pilot! The prototype provided by the Americans is in Shen Fei's hangar. However, at the beginning, this plane was flown by the Americans, and until now, their own test pilots have only flown a dozen sorties on this plane, and if they let their test pilots go into the sky. I'm afraid I won't be able to bring out the performance of this fighter.

And if the American pilots are allowed to go to the sky, it will be related to Shen Fei's face, this is a confrontation exercise between his own side and Shen Fei's fighters, and the result is the use of foreign aid!

While Shen Fei was struggling with the selection of pilots, Cheng Fei was making his final efforts.

This is indeed a last effort, and if this confrontation exercise fails, the fate of this model of our own side will probably have to end. If we don't conduct confrontation drills, we may be able to breathe for more. And now, once a confrontation exercise is conducted, it is almost a life-and-death battle, and there is no way back.

These days, Chengfei's technicians have hardly slept well, especially as the chief designer of the flight control, Yang Wei has spent almost all day in the flight control design room and workshop.

When I learned that Cheng Fei needed an F110 engine. Pakistan was very generous in bringing an F110 engine that had just been assembled off the production line. It was airlifted to Chengfei, who removed the TF41 engine on the No. 4 plane, replaced it with the F110 engine, rewrote the control program of the engine in the flight control, recalculated the impact of the air intake and other things on the engine, and made various corrections. In normal times, it would be a few months of work, but now, it is only a month!

And the improvement of this 004 is not only in the engine. Pakistan has also sent a special paint, which is said to absorb radar waves on the seams of various aircraft.

In addition, other aspects are also being improved, for example, Pakistan has also sent a set of optoelectronic devices, which are integrated into the fire control system.

According to Pakistan, this set of optoelectronic devices is called an optoelectronic radar!

Modern fighters, the main means of detection is radar, however, at some times, the use of radar is not good, for example, in a complex electromagnetic interference environment, or when silent flight is required, can not actively turn on the radar, in this way, passive optical detection equipment, can be very useful.

When it comes to this kind of optoelectronic device, the first thing that may come to mind for the average military fan is the OEPS-27 series of optoelectronic systems of the Su-27 and MiG-29, in fact, long before the birth of these systems, the United States also had similar systems, such as the Tomcat fighter equipped by Pakistan, which has an AN/AL-1 tactical camera reconnaissance system, and the core of this reconnaissance system is a long-distance optical television, Pakistan is based on this system, Together with the systems of the OEPS family of the Soviets, captured from the battlefield, a new optoelectronic radar was successfully developed!

This kind of optoelectronic radar, using the advanced technology of Western Europe, can reach a detection range of 80 kilometers, more than the Su-27's 50 kilometers, the imaging will be projected on the display screen in the aircraft or on the flat display, so that the fighter in the silent flight to maintain a grasp of the surrounding airspace.

The fire control research and development team is also actively integrating this system, leaving time for Chengfei not to use years, months, and days, but to calculate in seconds!

Their eyes are red, their heads are dizzy, they are still holding on, this time, Cheng Fei must not lose, and he must win beautifully!

Time passed quickly, and finally, three days before the agreed confrontation drill, all the systems had been tinkered with, and the whole aircraft was in good condition, although it was already more than three o'clock in the afternoon, it was still decided to conduct a test flight.

In fact, in China, the test pilots are not from an aircraft research institute, but belong to the state, and they are test pilots trained by the state, but these test pilots have been involved in the development of the aircraft synchronously since the No. 10 project was established, and put forward a lot of valuable opinions, so they are also very much looking forward to continuing to develop the No. 10 project.

And Lei Qiang, who has flown a variety of fighters at home and abroad, not only flew the F-16 in Pakistan, but also flew the F-16 equipped with them in the United Kingdom, and has rich flight experience.

Now, seeing this No. 004 test machine whose appearance is different from the previous ones, Lei Qiang is also excited, the partition of the air intake is gone, it has become a bulge, the front end of the nose is equipped with optoelectronic equipment, and the shape of the nozzle of the engine in the tail has also changed, this is already a reborn fighter!

Stepping into the cockpit, Lei Qiang calmed down and made various preparations before takeoff.

The canopy was closed, the individual electric doors were opened, the engine was started, and the roar of the tail followed.

Communicating with the tower, Lei Qiang released the brakes.

The F110 engine in the tail emitted a blazing flame, pushing the fighter and sliding quickly on the runway, although it was only a few seconds, Lei Qiang already felt that the engine of this fighter had become more powerful! The acceleration performance of the fighter is even better!

In the past, it was necessary to run more than 400 meters, but now, just 300 meters away, Lei Qiang felt that this fighter was ready to go! He gently pulled the lever back, and the fighter suddenly became lighter and had already left the runway!

In the past, the afterburner thrust of the TF41 engine was less than 110 kN, but now the F110 engine has an afterburner thrust of more than 1200 kN, an increase of 10 percent of the thrust!

After taking off, Lei Qiang continued to pull the lever, and the No. 10 plane, almost at an angle of 70 degrees, climbed upward.

The people watching on the ground immediately cheered. This aircraft has been replaced with more powerful engines and has greater potential!

Lei Qiang continued to climb, and when he reached 15,000 meters, he began to bulldoze the nose of the aircraft, and now, it was necessary to test the high-altitude performance of the aircraft.

Due to the use of a nose and air intake similar to the F-16, there is no adjustment plate, although the weight is reduced a lot, but the maximum speed of the No. 10 machine is not large, and when there is no external plug-in, it only reaches Mach 1.6 at high altitude, and the F-16 only flies over Mach 2 when it is tested, and almost does not fly over Mach 1.5 when it is in peacetime combat.

Now, the No. 10 aircraft has been replaced with a new engine, and at the same time, it also uses the DSI intake duct newly developed by Chengfei, and now, it is time to test the basic performance of the aircraft!

At an altitude of 15,000 meters, the fighter plane continued to accelerate, and the air flow blew through the airspeed tube, through the air data computer, and finally displayed on the liquid crystal display, and at the same time, it was also synchronously displayed on the backup Mach meter and airspeed meter.

At this time, it is not the era of the glass cockpit of later generations, the tenth machine is already a fighter that Cheng Fei can access to all the advanced technologies, such as the use of the 1553B data bus, and the cockpit has a flat and two layout, but it still uses a lot of mechanical instruments in the middle, in case the electronic system fails, you can also rely on these basic instruments to fly.

The watch hand was constantly turning, and the fighter continued to accelerate, and finally, it stopped at Mach 2.2, which is already the maximum flight speed of high-altitude level flight!

During acceleration, the engine worked smoothly and normally, indicating that the design of this bulging air intake was a complete success! Lei Qiang's heart was even more excited, the afterburner that had just lasted had been going on for five minutes, and the fuel was almost half consumed, turning off the afterburner, he watched the speed slow down, and skillfully pushed the operating lever, and the fighter made a roll with agility.

"Damn!" Lei Qiang suddenly shouted.

"004, report the situation!" Immediately, there was a concerned greeting from the ground in the headphones.

"004 report, everything is normal, it's just too sensitive!" Lei Qiang suppressed his excitement and reported to the ground. (To be continued......)
