The pl-5c fighting missile uses infrared guidance. The disadvantage of this passive guidance method is that it can hit the target's infrared signal characteristics. The so-called infrared model characteristics refer to thermal energy characteristics.
The target target machine uses electric energy propulsion, and the thermal energy characteristics are greatly reduced. At low speeds, the thermal energy characteristics generated by friction between the body and the air are also very weak. This is the difficulty.
Li Zhan had already flew around the target aircraft three times and could not make up his mind to start the fight.
He was basically sure that this was a problem deliberately raised by the air defense base. Not only was the target, but he also had the meaning of testing the 101st Brigade. The pressure suddenly became high.
Several times he couldn't help but use the air cannon to knock it down, but unfortunately, the shooting director Cao Fufei probably wore a pair of pants with the air defense base and put the air cannon shells down.
Pull the distance closer? The infrared feature does not meet the minimum detection and measurement requirements of the pl-5c seeker, it will be useless. The missile will still turn a blind eye to an unknown direction. It is not impossible to turn around and load the aircraft.
The fighter jets are fleeting, and the battery life of the unmanned target aircraft with power propulsion is obviously very limited, so we can't hesitate anymore. Li Zhan thought of a local solution and decided to take a risk. He once again checked the real-time data of the atmospheric data system and
The flight attitude information of the fighter jet, paying special attention to the wind direction, atmospheric pressure and the flight attitude information of the target, among which the speed and heading height of the target is the most important.
"Tower, I'm Dongyao, I'm asking for shooting, it's over." Li Zhan felt 80% sure in his heart and immediately asked for instructions, and then repeated the instructions in English.
Everyone was waiting to see how Li Zhan would fight. The purpose of arranging such sudden changes was to test the pilot's on-the-air response and how the task should be completed without any attack conditions.
Fang Chenghe replied, "Dongya, clear air in front of you, you can shoot, it's over."
"clear."
Li Zhan accelerated his flight towards the target at 10 o'clock, turned around and returned ten kilometers, pointing to the left side of the target target aircraft, and continued to approach at a speed of 400 kilometers per hour. He gave the pl-5c under the left wing hanger
Powered up, seeker preheated, and the fighter's sighting device has locked the target target. At a five-kilometer position, Li Zhan switched the aiming method to aiming the air cannon, and calculated the advance amount. He was two points away from the target target.
Missiles were fired over a distance of five kilometers.
When he saw the pl-5c shoot straight towards the front of the target aircraft, Li Zhan put the accelerator rod in the slow position. In order to slow down as soon as possible, he actually raised the speed reduction plate on his back. The No. 01 J-11b looked very similar.
Angry cockfighting, the hair on the neck stood up and looked ferocious.
After launching the missile, you should turn away or even avoid maneuvers. However, in order to use a camera installed on the flight helmet to capture the shooting effect, Li Zhan must be as close to the target aircraft as possible. In order not to rush into the kill range when the missile explodes,
He had to use the method of raising his back speed plate to quickly slow down.
The pl-5c missile really doesn't seem to see the target anymore. Its ballistic point is hundreds of meters ahead of the target aircraft, which means that the seeker failed to detect the infrared signal of the target.
Both the Tower and Beiku Tactical Intelligence Interaction Center can see the small red dots representing the PL-5c missile and the small green dots representing the target aircraft. It is obvious that this is a sign of running the target. The pl-5c fighting missile
If the target is locked, it will catch up with the target. The entire flight process shows an irregular arc, and the maximum overload capacity of 20 g is to achieve a hit. Now the pl-5c fighting missile is flying in a straight line
, indicating that the seeker failed to obtain the target signal and was in an unguided state.
Li Zhan had already scolded him for being too shameless in his heart. The target aircraft brigade was too shameless. The infrared signal characteristics of this target aircraft must be lower than the detectable value of pl-5c, otherwise the missile would not have no reaction at such a close distance.
It is purely intentional tricking people, and if you shoot in the normal way, you will definitely run the target.
This is not live-fire shooting training, it is clearly a game of Little Prince of Pit Pulling Rods.
"Fortunately, I have two tricks, otherwise I would have let you guys get cheated." Li Zhan said in his heart, holding the pl-5c fighting missile about one kilometer away.
Several experienced leaders in the tower saw the clues first. It would be strange if Li Zhan was only at this level. However, everyone thought that things were not that simple, but they didn't know what Li Zhan had left behind.
A miracle happened.
The stupid pl-5c fighting missile hit the target aircraft during flight...
The moment it hit, the fuse started the explosion of the warhead, tearing the target machine leisurely and leisurely to pieces. The operator on the ground was stunned when he saw the signal breaking and the black screen. The tower and Beiku tactical information
A group of people from the interaction center saw this amazing scene through the camera installed on Li Zhan’s flight helmet - the missile did not lock in the target target aircraft but actually hit it.
Is this luck?
Is good luck really so magical?
The first guess that popped up in everyone's head was different. The leaders were shocked and quickly calmed down and then thought of a possibility - Li Zhan let the pl-5c's ballistics overlap with the target aircraft's route at a certain point
As a result, a collision occurs, in other words, the target is not knocked down but hit.
Use missiles as air cannons!
"The tower, the target target aircraft has been destroyed and is searching for the next target, it is finished." Li Zhan reported proudly, and controlled the fighter aircraft to leisurely leave the airspace and then continued to shoot and train.
Fang Chenghe was so proud that he suppressed his smile and replied, "Dongyao can continue to perform the shooting mission, it's over. He's playing well."
"Perform normally, it's over." Li Zhan said that he knew that Commander Liang must be on the tower, and the Target Machine Brigade would definitely not dare to do this without the approval of the base headquarters. It is likely that it was instructed by Commander Liang.
Liang Pengfei twitched slightly. The target aircraft brigade carefully designed such a target. He analyzed and studied it many times and was completely arranged to target the shortcomings of the pl-5c fighting missile, which happened to be stuck.
The minimum detection line of the passive infrared seeker of the missile was not expected to be solved simply and roughly by Li Zhan using such a rustic method - if the seeker doesn't work, I will throw it away.
Smashed over like a stone!
But he soon felt relieved. Isn’t it just that he had a problem with the 101st Brigade that he wanted to see real combat effectiveness?
If you think about it carefully, this method of using missiles as air cannons will look simple at first glance. The principle is the same as using air cannons to hit air targets, but it is more difficult. The shells are powerless and can be shot out by relying on bottom fire to shoot out the ballistic
The difference is regular, but the missile has its own driving force and has multiple wings. The trajectory is extremely difficult to follow during the flight. The flight process shows an acceleration state, and the flight altitude and direction are affected by the wind.
It's 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 a little disappointed - did he finally fail to test his combat power limit?
