Chapter 2423: Missile launch

Different missiles have different attack processes. For example, infrared missiles use the infrared rays of the opponent’s fighter aircraft to lock and track targets. Medium-range missiles use radar. Among them, semi-active missiles use radar to emit electromagnetic waves and reflect back to the missile. The target can be tracked in the missile's seeker. Active radar missiles use the missile's own seeker to transmit and receive signals. It does not require continuous tracking and irradiation by the carrier. All of these require a strong radar on the target. The reflective area will do. How did you overcome these technical problems?
In the past, Qin Guan didn't study specific technology, he was just a technical porter. Since he came here this time to participate in the battle against the stealth machine, Qin Guan is very concerned about the final process.
Now, after hearing Qin Guan's question, the experts present showed a knowing smile: "Yes, this problem has also caused us a big obstacle."
They use metric-wave radar to find targets, and can even locate them accurately, but how do they guide with metric-wave radar? It is absolutely impossible to put a meter-wave radar antenna inside the seeker of the missile, and the changes to the missile are too large to realize.
Semi-active guidance. Facing this problem, what about active guidance? The missile seeker is inherently small, and the radar antenna is also very small. For ordinary fighters, the operating range is only 20 to 30 kilometers. For this kind of stealth aircraft, it is difficult to find, let alone attack. .
It doesn't work whether it is active or semi-active. So, how to guide the missile? Facing this problem, they took a lot of detours at the beginning, and then suddenly wanted to understand, then simply use the oldest way!
When the missile first started, what was it used? During the World War, missiles were the first to appear. The tail of this missile is dragged with two wires, and the pilot behind it uses the handle to operate it. This is the simplest general principle of airplane model, in fact it is command guidance!
The wire quickly disappeared and became a radio command guidance. This kind of guidance was very popular in previous missiles. It was not until the new generation of long-range missiles that semi-active seekers were widely used. , And now, they simply brought out the simplest command guidance directly!
In fact, semi-active missiles are command-guided in the first half of the flight. Therefore, this method is easy to transplant. The main reason is the communication problem between devices. The data of the own meter wave radar and the Hongqi 9 missile are communicated. With the development of data link technology to the present, this problem is easy to solve.
"Of course, compared with the previous technology, our current guidance is more precise, because the command guidance has not reached the level of terminal attack. At the final stage, we must improve the accuracy of guidance as much as possible, and at the same time let the missile guidance Work with the maximum power of the head to find the target as much as possible. As long as the detonation is close to the target at a distance of 50 meters, we are fully confident that we can shoot down the target. This is also the basis for this exercise."
In the end, how to detonate and how to reach the vicinity of the target is the most critical issue. For the large Hongqi 9 missile, the weight of the warhead is close to two hundred kilograms! (It can be compared with a bag of flour. A bag of white flour is only 50 kilograms. The warhead of a missile is almost equivalent to four bags of white flour.) The lethality of this warhead is great, even at low altitude. , The kill radius is more than 60 meters. At high altitude, the kill radius is two to three hundred meters. Therefore, if the missile can detonate close to the target 50 meters, the target will definitely not run.
This requires multi-faceted coordination and joint efforts. Now, while speaking, interception has entered the final process.
"Attention, the target has entered within one hundred kilometers."
"Missile unit, start the launch procedure."
The atmosphere became tense in an instant. The red flag nine missile launch tube outside was opened, waiting for the last moment.
"The goal is within eighty kilometers."
"Sixty kilometers!"
"Fifty kilometers!"
"Attention, the radar enters the highest precision mode, transmits commands through the data link, and the missile is launched!"
emission!
Qin Guan was at the door of the command vehicle, and when he heard the command to launch, he immediately opened the door. He wanted to go out and have a look. The Xiucai was quick with his eyes and grabbed Qin Guan and covered his eyes.
A hot orange beam emerged from the upper end of the launch tube. Above the fireball, a milky white missile was accelerating and climbing upwards. The flames continued to spread outward, turning into billowing smoke, which was launched at night. This launch is more spectacular, but it also has a lot of damage to vision.
What if you suddenly see the light in the dark? There is a vast expanse of whiteness in front of me, I can't see anything! What if it is a strong light? It may even cause damage to eyesight!
After the last incident, the scholars protected Qin Guan in every possible way, for fear of any accidents to Qin Guan, especially under the current circumstances, if Qin Guan went out rashly, it would not only damage his eyesight from bright light. The problem is the accidental explosion that the missile may face.
The inside of the missile is full of high-energy fuel. Under normal circumstances, this fuel will not cause problems, but no one can guarantee that any missile will not cause problems. What if it accidentally explodes?
It may also be affected here. Inside the launch vehicle, at least there is armor protection on the outside of the vehicle. If it is exposed to the outside, once an accident occurs, the Xiucai cannot afford the consequences.
As a result, Qin Guan could only be held back by the scholar. Although he wanted to cut the spirit of the scholar, it was not of much use anymore. The missile launch, the most spectacular scene, had disappeared!
If it is a formal battle, it will definitely use two salvos, which can improve the hit rate, but now, there are still people on the target plane, who are still the best pilots, so there is no need to use this method, just one verification Will suffice.
The missile flew out, this does not mean the end, but just the beginning of another set of procedures, the missile began to fly towards the target under the guidance of radio instructions!
The meter wave radar releases strong electromagnetic waves, all of which are gathered together, staring at the target closely. The high-speed DSP chip is rapidly calculating, accurately positioning the target and meeting the needs of guiding the missile.
At this time, Chen Rui still knew nothing. Although the light when the missile is launched is hot and dazzling, it is also a challenge to the human eye to see fireworks on the ground 50 kilometers away.
