Chapter 2423

Different missiles have different attack processes. For example, infrared missiles use the infrared of the enemy's fighter fuselage to lock and track the target. Medium range missiles use radar. Among them, semi-active missiles use radar to launch electromagnetic waves, which can be reflected back into the missile's seeker to track the target. Active radar missiles, It uses the missile's own guidance hair to shoot and receive signals without the continuous tracking and irradiation of the carrier, which requires the target to have a strong radar reflection area. How can we overcome these technical problems?

In the past, Qin Guan didn't study specific technology. He was just a technical porter. Now that he came here to participate in the fight against stealth aircraft, Qin Guan was very concerned about the final process.

Now, hearing Qin Guan's question, the experts present showed a divine smile: "yes, this problem has also caused great obstacles to us."

They use meter wave radar to find targets and even locate them accurately, but how to guide them with meter wave radar? It is absolutely impossible to put the meter wave radar antenna into the missile seeker. Moreover, the changes to the missile are too large to be realized.

Semi active guidance. Facing this problem, what about active guidance? The missile seeker is small in size, and the radar antenna is also very small. For ordinary fighters, the operating range is only 20 or 30 kilometers. For this stealth aircraft, it is difficult to find, let alone attack.

Whether active or semi-active, it will not work. Then, how should we guide the missile? Faced with this problem, they also took a lot of detours at the beginning. Later, they suddenly figured out, so they just used the oldest way!

What was used when the missile first started? During the world war, missiles first appeared. The tail of this missile dragged two wires, and the pilot behind it operated with a handle. This is the general principle of the simplest aircraft model, which is actually command guidance!

The wire soon disappeared and became radio command guidance. This guidance method was very popular in previous missiles until the semi-active seeker was widely used in the new generation of long-range missiles. Now, they simply take out the simplest command guidance again!

In fact, the semi-active missile is command guided in the first half of the flight. Therefore, this method is easy to transplant, mainly due to the communication problem between equipment. It communicates with its own meter wave radar and the data of Hongqi 9 missile. With the development of data link technology, this problem is easy to solve.

"Of course, compared with the previous technology, our current guidance should be more accurate, because the command guidance does not reach the degree of terminal attack. At the terminal stage, we should improve the guidance accuracy as much as possible, and let the missile seeker work at the maximum power to find the target as far as possible. As long as we detonate at a distance of 50 meters close to the target, we will have complete confidence Enough to shoot down the target, which is also the basis for judging this exercise. "

Finally, how to detonate and how to reach near the target is the most critical problem. For the large Hongqi 9 missile, the weight of the warhead is close to 200 kg! (compared with flour bags, the largest bag of white flour is only 50kg, and the warhead of a missile is almost equivalent to four bags of white flour.) this warhead has great lethality. Even at low altitude, the killing radius is more than 60 meters, and at high altitude, the killing radius is two or three hundred meters. Therefore, if the missile can detonate 50 meters close to the target, That target will never run.

This requires multi-faceted coordination and joint efforts. Now, the interception has entered the final process.

"Note that the target has reached within 100 kilometers."

"Missile forces, launch procedures."

The atmosphere became tense in an instant. The cover of the launcher of Hongqi 9 missile outside was opened and waiting for the last moment.

"The target is within 80 kilometers."

"Sixty kilometers!"

"Fifty kilometers!"

"Note that the radar enters the highest accuracy mode, transmits instructions through the data link and launches the missile!"

Launch!

Qin Guan was at the door of the command car. Hearing the command to launch, he immediately opened the door and wanted to go out to have a look. The scholar was quick in his eyes and hands. He immediately grabbed Qin Guan and covered his eyes.

The hot orange light beam comes out from the upper end of the launcher. Above the fireball, a milky white missile is accelerating and climbing upward. The flame continues to spread outward and becomes rolling smoke. It is launched at night. This launch is more spectacular, but it also does great harm to vision.

What happens if you suddenly see light in the dark? There is a vast expanse of white in front of me. I can't see anything clearly! What if it's a strong light? It will even damage your eyesight!

After the last incident, the scholar took great care to protect Qin Guan. He was afraid of any accident. Especially now, if Qin Guan goes out rashly, it will not only damage his eyesight, but also the accidental explosion of the missile.

The interior of the missile is high-energy fuel. This fuel will not go wrong under normal circumstances, but no one can guarantee that any missile will not go wrong. What if it explodes accidentally?

It may also be affected here. In the launch vehicle, at least there is armor protection outside the vehicle. If it is exposed outside, once there is an accident, the scholar can't afford the consequences.

Therefore, Qin Guan could only be held by the scholar. Although he wanted to cut the scholar's spiritual point, it was no longer of great use. The most spectacular scene of missile launch had disappeared!

If it is a formal battle, two volleys will be used, which can improve the hit rate. However, there are still people on the target plane and the best pilots, so there is no need to use this method. Only one verification is enough.

The missile flew out, which does not mean the end. It is 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 gather together and stare at the target closely. The high-speed DSP chip is calculating quickly to accurately locate the target and meet the needs of guiding the missile.

At this time, Chen Rui still knows 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.
