The PL-5C combat missile uses infrared guidance, and the disadvantage of this passive guidance method is that whether it can hit depends on the infrared signal signature of the target, and the so-called infrared model characteristics refer to the thermal energy characteristics.

The target aircraft uses electrical propulsion, and the thermal energy characteristics are greatly reduced, and the thermal energy characteristics generated by the friction between the body and the air at low speed are also very weak. Here's the difficulty.

Li Zhan had already flown around the target plane three times, and he couldn't make up his mind to fight.

He was already basically sure that this was a deliberate problem from the air defense base, and the target was not only him, but also the meaning of testing the 101st Brigade. All of a sudden, the pressure was great.

Several times he couldn't help but use the aerial artillery to bomb it down, but unfortunately the shooting director Cao Fufei estimated that he was wearing a pair of pants with the air defense base, and he was stunned to drop the aerial artillery shells.

Closing the distance? The infrared signature does not meet the requirements of the PL-5C seeker for the minimum detectable measurement, no matter how close it is, it will be useless, and the missile will still turn a blind eye and fly in an unknown direction.

The fighter is fleeting, and the endurance of the electrically propelled unmanned target aircraft is obviously very limited, and there can be no more hesitation. Li Zhan thought of a local solution and decided to take a risk. Once again, he looked at the real-time data of the air data system and the flight attitude information of the fighter plane, paying special attention to the wind direction and atmospheric pressure and the flight attitude information of the target, among which the speed and heading altitude of the target are the most important.

"Tower, I'm Dongyi, request to shoot, over." Li Zhan immediately asked for instructions from the tower after he was eighty percent sure in his heart, and then repeated the request in English.

Everyone was waiting to see how Li Zhan would fight, and the purpose of arranging such a sudden change was to test the pilot's impromptu reaction and how to complete the mission when there seemed to be no conditions for attack.

Fang Chenghe replied, "Cave, there is a clear space ahead, you can shoot, over." ”

"Understood."

Li Zhan accelerated to the direction of the target at 10 o'clock, turned around and returned at 10 kilometers, the nose of the plane pointed to the left side of the target aircraft, and continued to approach at a speed of 400 kilometers per hour. He energized the PL-5C under the pylons on the left wing, warmed up the seeker, and the fighter's sight had locked onto the target aircraft. At a position of 5 kilometers, Li Zhan switched the aiming method to that of an aerial gun, calculated the amount of advance, and launched the missile at a distance of 2.5 kilometers from the target aircraft. x33 update fastest mobile phone: ://x33 first release

When he saw the PL-5C shooting straight in front of the target aircraft, Li Zhan put the throttle stick in the slow position, and in order to slow down as soon as possible, he actually put up the speed brake on his back, and the No. 01 J-11B looked like an angry fighting, and the hair on his neck stood up and looked hideous.

After launching the missile, he should turn and detach or even make an evasive maneuver, but in order to use the camera attached to the flight helmet to shoot the shooting effect, Li Zhan should get as close as possible to the target aircraft. In order not to rush into the kill range when the missile exploded, he had to use the method of erecting a speed brake on his back to quickly reduce his speed.

The PL-5C missile really does not seem to be able to see the target, and its trajectory is pointed at a position of several hundred meters in front of the target aircraft, which shows that the seeker has not been able to detect the infrared signal of the target.

Both the tower and the Beiku Tactical Intelligence Interaction Center can see the small red dot representing the PL-5C missile and the small green dot representing the target aircraft, which is obviously a sign of target running. If the PL-5C combat missile locks on to the target, it will chase the target directly, and the whole flight process is an irregular arc, with a maximum withstand overload capacity of 20 G to achieve a hit. And now the PL-5C combat missile flies in a straight line, indicating that the seeker has not been able to obtain the target signal and is in an unguided state. X33 debut

Li Zhan had already scolded in his heart, the target aircraft brigade was too shameless, and the infrared signature of this target target aircraft must be lower than the detectable value of the PL-5C, otherwise it would be impossible for the missile not to react at such a close distance. This is purely deliberate to trick people, and if the shooting is carried out in the normal way, it is a proper target.

Where is this live-fire training, it is clearly a pit trolley game of the little prince.

"Fortunately, my brother has two hands, otherwise I would really let you guys get into a pit." Li Zhan said secretly in his heart, staring intently at the PL-5C combat missile about a kilometer away.

Several experienced leaders in the tower first saw the clues, it would be strange if Li Zhan really only had this level, but everyone felt that things were not so simple, but they didn't know what Li Zhan had left behind.

A miracle happened.

The stupid PL-5C combat missile collided with the target aircraft in the middle of the flight......

The moment it collided, the fuse activated the warhead and exploded, tearing the leisurely cruising target aircraft to pieces. The operator on the ground was dumbfounded when he saw that the signal was cut off and the black screen was black. A group of people from the control tower and the Beiku Tactical Intelligence Interaction Center saw this surprising scene through the camera installed on Li Zhan's flight helmet -- the missile did not lock onto the target, but the target plane actually hit it.

Is this luck?

Is good luck really so magical?

The first conjecture that pops into everyone's head is different. Several leaders were shocked and quickly calmed down, and then thought of a possibility - Li Zhan made the trajectory of the PL-5C coincide with the path of the target aircraft at a certain point, so that the collision occurred, in other words, the target was not shot down but knocked down.

Shoot missiles like aerial artillery!

"Tower, target aircraft has been destroyed, searching for the next target, over." Li Zhan proudly reported, maneuvering the fighter plane to leisurely get out of the airspace and then continue the next step of shooting training.

Fang Chenghe was proud now, and he replied with a smile, "Dong Yu can continue to carry out the shooting mission, over." Well played. ”

"Normal play, over." Li Zhan said that he knew that Commander Liang must be at the tower, and that the target aircraft brigade would not dare to do so without the approval of the base command, and it was probably Commander Liang's instructions.

The corners of Liang Pengfei's mouth twitched slightly, the target aircraft brigade carefully designed such a target, which was analyzed and studied many times by the people in the front and back and the combat department, and it was completely arranged for the shortcomings of the PL-5C combat missile, and it happened to be stuck in the line of the lowest detection heat of the missile's passive infrared seeker, but I didn't expect it to be solved simply and rudely by Li Zhan with such a dirty method - if the seeker didn't work, I would smash it like a stone!

However, he was quickly relieved, didn't he give the 101st Brigade a problem just in the hope of seeing real combat effectiveness?

If you think about it carefully, the method of using missiles as aerial artillery is very simple at first glance, and the principle is the same as using aerial artillery to hit an air target, but the difficulty is even higher. The artillery shell is unpowered, relying on the primer to push out, and the poor trajectory of hitting out is regular, but the missile has its own propulsion, there are many wings, and the trajectory is extremely difficult to follow the law during the flight, the flight process presents a state of acceleration, and the flight altitude and flight direction are greatly affected by the wind, and it is almost impossible to accurately control its hit point.

Li Zhan was not only able to do it, but also completed it in a very short time, which shocked everyone and was also a little disappointed - finally failed to try the limit of his combat effectiveness?
