"Fire control system, okay?" Before getting on the plane, Qin Feng asked again.

The confrontation finally came, on this day, a lot of air force officers came to the test flight yard, all waiting for this moment, the confrontation at this time is not fair to J-10.

Although they are all produced by themselves, the J-11 is assembled, and the aircraft assembled by oneself is enough to ensure the same process as the original aircraft, etc., but what about the J-10, which is still flying test.

Qin Feng is no longer worried about the aerodynamic performance of the aircraft, during this period of flight, several performances, the control of this aircraft is already very easy, Qin Feng is now worried about fire control.

If you want the other party to admit defeat, you have to have the final say in the fire control system, which simply means that you can lock on to the other party first, and you will win, after all, this confrontation is divided into several projects, and the radar lock on the middle range is quite important.

The nose of the Su-27 fighter is very large, and the size of the radar antenna is large, so everyone thinks that the Su-27 must be able to lock on to the target first, but Qin Feng believes that his own technology is more advanced, because his own flat slot antenna.

As long as there is no glitch!

"No problem!" Qin Xue said to Qin Feng, now, it is still Qin Xue who is helping to test fly the radar equipment of the No. 03 aircraft together, they have long known about this confrontation, and they are all ready, and now, it is also a comparison between domestic avionics and imported avionics, let everyone see, domestic avionics is not weak at all, or even stronger!

As long as the fire control system is fine, Qin Feng is relieved, he looked at his wings, according to the requirements of the confrontation, he mounted two Thunderbolt-11 missiles, two Thunderbolt-8 missiles, in fact, the real medium-range target has not yet started, but, when the plane is in the confrontation, it must be hung with missiles, otherwise it is similar to cheating, there is a big difference between the maneuver with missiles and the maneuver without missiles, if you don't hang missiles, isn't that cheating?

Qin Feng heard Qin Xue's answer, and was immediately satisfied, as long as the fire control system was fine, then he had nothing to worry about.

Get on the plane!

On the other side, Li Cheng, the pilot of J-11, also stepped into the cockpit, if the two fighters are compared together, you can see that J-11 is more tall, after all, this kind of aircraft is a heavy aircraft, Li Cheng knows that the burden on his shoulders is very heavy, after all, in the army, there are many people who like J-11 fighters, they definitely don't want to see this plane be abused by J-10 fighters, they are looking forward to being able to abuse J-10.

The runway of the test flight institute is very wide, J-11 first slid on the runway, the two three uncle-in-law engines roared, and soon climbed and flew into the sky, the pilot seemed to be showing off, and also took off at a big angle of attack.

Qin Feng had a smile on his face, if he wanted to talk about climbing at the angle of attack, he was also absolutely responsible, there must be many people who had not seen the take-off of the Jian-10, right?

More than sixty degrees, take off!

When this big angle of attack came out, the audience present immediately exclaimed.

J-11, there is an angle of attack limiter, if you don't let go of the angle of attack limiter, it can only be pulled to 30 degrees at most, now, J-10 is completely determined by the digital flight control, as long as there is no danger, the flight control will be all released, so, this take-off, it will be even more rapid.

"Unexpectedly, our J-10 is not bad." Watching the J-10 take off, some people who originally only liked the Su-27 began to express their admiration, and they always felt that their domestic industry could not reach it, but as a result, the scientific researchers came up with such an advanced fighter!

Of course, there are also people who are not convinced, hum, what is this, look at the back, one just takes off.

After taking off, the two fighters separated into two directions, and the radar on the ground was monitoring the position of the two fighters, looking forward to the beginning of the medium-range air battle.

According to the predetermined plan, the two sides opened up a distance of almost two hundred kilometers, and then, began to look for each other's traces in the sky, to see who could find it first, to see who could attack first!

The radar of the Su-27, that is the essence of the USSR, absolutely no problem!

A group of officers who like the Su-27 are still complacent at this time, and in the sky, Qin Feng has already started to activate the radar system.

No matter what radar it is, the principle is the same, emit electromagnetic waves, return when encountering obstacles, and then receive, and complete a detection, but, how to transmit this electromagnetic wave, how to detect the wave after recovery, then there is a lot of attention, it is definitely not whose power is large, whose efficiency is high, MiG-25's radar legend can burn rabbits, but what, most of the energy is dissipated, there is not much really useful energy, if it is estimated to be a microwave oven is more suitable.

The nose radar of the J-10 fighter began to rotate, and the flat panel antenna radiated electromagnetic waves into the surrounding air.

It's not that the radar is plate-shaped, so it doesn't need to be rotated, it still has universal joints, there are restrictions on elevation and depression, etc., and only a sector area in front can be seen, which is determined by the basic principle, only that kind of phased array radar has completely no such limitations.

Now, the radar of the J-11 fighter is also fully powered, radiating electromagnetic waves around, and both sides are trying to find each other's traces, who can win?

The distance is rapidly approaching, one hundred and fifty kilometers, one hundred kilometers, and at this time, there is already a looming bright spot on the radar screen of the J-10 fighter!

Qin Feng quickly operated, followed up on this bright spot, radiated all the radar waves, and then, the bright spot became clearer!

"003 Discovers Target!" Qin Feng shouted on the radio, there is also a recording device in the cockpit, so this cannot be faked: "The distance is one hundred!" ”

What the? It was J-10 who first discovered the target? How is this possible? It's filled with domestic radar equipment, when did the domestic radar have such a strong performance?

"Locked on, eighty away!" Qin Feng continued, as all the electromagnetic waves were radiated, clear bright spots appeared, followed by high-frequency pulse waves, which were enough to provide more data.

Just now, I used the PDS mode, the pulse Doppler search mode, just like a big flashlight, constantly illuminating the road, what if I found something in front of me? Then all the beams of the flashlight are gathered into a single point, this is PDSTT, Pulse Doppler Single Target Tracking, this mode is a mode that can find and lock the other party at the farthest distance!

When Qin Feng's report went back, those people on the ground who admired the Su-27 couldn't sit still in an instant, how could it be, how could this be?
