The two fighters approached quickly in the sky, and Li Cheng at this time only felt a kind of shame, that's right, the Su-27 fighter is the most advanced fighter introduced in China, and the pilots who operate this fighter have always been quite proud, and feel that it is the most beautiful in China.

Now, it will actually lose to J-10, in over-the-horizon combat, the Su-27 is like a fly without a head, if it is on the battlefield, such an end is also very terrible.

How so? This is the first fighter in China with advanced medium-range missiles, how can it be so weak?

Li Cheng had an urge to vomit blood, but he knew that now he was representing the echelon of heavy aircraft, representing Shenyang, and he must not have emotional fluctuations, otherwise, he would definitely lose, especially now that he has reached the range of close-quarters fighting.

You must know that the confrontation between heavy aircraft and medium aircraft has an innate advantage that the power of the fighter is strong, and the engine is two, but the other equipment will not increase to twice the weight of the original, which leads to a fairly rich power reserve, which can make up for the loss of air combat at any time.

The other party only has one engine, how can it be compared with himself?

In the field of vision, the target is getting bigger and bigger, bigger and bigger, Li Cheng's fingers began to move back and forth on the weapon selection switch, next, it should be close combat, in close combat, the helmet sight can allow the pilot to get the advantage of the first enemy to find and attack the enemy, that's right, turn to the helmet sight!

Like the other party, Qin Feng at this time is also switching weapon switches, compared to the Su-27's weapon launch method, the J-10 is very simple, there is only one radar, so he only needs to change the radar mode and reach the ACM.

Don't ask for more, but for refinement!

The ACM mode, itself called the close-quarters combat mode, as the name suggests, is used for close-quarters air combat, and its mode, and the previous modes, are also a little different.

In the front of the long-range air combat, it is necessary to search for a wide range of targets, and the time to complete a scan will be very long, and in the close-range combat, both sides are carrying out a large overload maneuver, so the scanning speed of the radar must be fast, it does not need to be too far away, but the rotation of the radar antenna must be fast, and the situation of the surrounding airspace can be quickly judged. Generally, it is several times higher than the regular search, and at the same time, the last one is to be able to track stably.

When the other party is scanned, the other party will definitely overload the maneuver, for the radar, as long as it is scanned, it must be able to track stably, as long as the nose can keep up, then the radar must also keep up.

What are these requirements?

The heavier the antenna, the slower it rotates, and the less flexible it is. This is also an advantage of flat slot radar antennas, the antenna weight is small!

Look at those inverted card antennas, although the antenna does not move, the feed rotates, the volume and weight are not small, of course, the most ordinary pot lid antenna is the most difficult to move quickly.

Secondly, it is necessary to have the fast processing ability of the target, the faster the processing speed, the stronger the tracking ability, so, don't look at a pulse Doppler radar, the technology inside is quite strong, in this regard, the domestic performance has surpassed the imported Sukhoi fighter!

So, what signals does the radar have to provide?

When the radar finds and tracks the target, it will continuously measure the range of the target, measure the bearing, and after the computer processes it, the signal will be sent to the infrared seeker of the missile, and the seeker will turn to the direction of the target, track the target, and after turning to stable tracking, the missile can be locked, and then get the opportunity to launch.

In the past, it was not easy to operate a missile, you had to measure the distance of the target, you had to follow closely behind the opponent, input all kinds of data into the missile, and in the process of doing all this, you had to keep maneuvering to ensure that you were always directly behind the opponent, which was definitely a technical job.

At the beginning, the radar was not needed to launch the missile, the laser rangefinder was used to measure the distance, the optical device was used to measure the angle, etc., and later, the radar rangefinder was used to improve the Jian-7, which was the radar rangefinder, which was prepared for the launch of the missile, and now, nothing is needed, all the data are handed over to the radar to be processed, and handed over to the fire control system for automatic processing, so that for the pilot, as long as he concentrates on fighting, he can do it.

Besides, there is also the flat display, all kinds of firing information are displayed on the flat display, sitting in the glass cockpit of the third-generation aircraft, Qin Feng felt a burst of relaxation, long-distance air combat confrontation, Su-27 is lost, if you fight in close combat, the other party has no chance!

They do not have a beautiful appearance to achieve a decisive victory, they lack advanced electronic technology, and in modern warfare, advanced electronic technology plays a decisive role, yes, it is decisive!

Qin Feng turned on the afterburner and began to climb high, as a fighter with insufficient power, if he wanted to store enough energy before the fight, that was to use the advantage of altitude, at the same time, he was still changing direction, and the plane drew an arc and flew diagonally towards the opponent.

At this time, Li Chengcheng on the opposite side secretly shouted that it was not good, the direction in which the other party flew over was exactly the direction of the sun, so that in a flash, his helmet sight would not be easy to use, and the optoelectronic device would not be easy to use.

Go to Radar Mode!

Li Cheng quickly flicked the switch, turned the fire control system back to radar mode, and tried to lock the other party with radar, he looked down at the radar screen, and wanted to operate the radar to complete the locking action, but it was too late!

"The J-10 fighter has completed a lock!" Now the air-to-air missile, in addition to the tail chase attack, can already attack head-on, J-10 carries the Thunderbolt-8 missile, in the head-on, first locked the J-11, completed the first round of attacks in close combat!

The fire control system is too fast, almost switching from mode to missile lock, it doesn't take more than three seconds, at this time, the other party is estimated to have just flipped six switches in a hurry, right?

Yes, for one conversion, they have to flip six switches, three sets of fire control systems, is it easy to use?

Of course, it's not easy to use, but there is no way, because the electronic systems of the Soviets are not advanced enough, and many of them that can be done automatically are equipped with manual control, resulting in a considerable amount of their operation, in comparison, the operation of the J-10 is very simple.
