Chapter 2446: No escape zone

As a long-range missile, the maximum range of the Pili-13 has actually exceeded one hundred and fifty kilometers. When it is launched normally, the target has entered the inevitable zone at about one hundred kilometers. Now, During the test launch, Chen Rui launched the missile at a distance of 120 kilometers, which was also a preset data for this experiment.
The missile is flying forward. Because the speed is not fast, the ram mode of the missile has not been activated. Although the two rectangular air inlets are continuously sucking in air, they do not enter the engine behind, but pass directly. The rear exit went out again. At this time, the initial acceleration was not rapid. Compared with the solid rocket engine, the initial rapid acceleration is incomparable. The ramjet needs speed to work.
Now, the fuel continues to enter the back combustion chamber and comes out of the ram nozzle. The missile quickly exceeds the speed of sound and continues to accelerate and accelerate. When the speed exceeds Mach 2, the outlet of the air inlet is blocked. All flowed into the ramjet engine!
Ordinary engines want to take in more air, they need a compressor in front, a compressor with multiple impellers, which is the most common form of modern jets, and a ramjet is not needed, because with the speed Increase, the air it hits by itself is enough for it to burn!
When the ramjet started to start, the whole missile seemed to be kicked fiercely, and the momentum immediately came up. The missile accelerated swiftly and quickly increased to Mach 3 and Mach 4!
After reaching Mach 4, the missile has reached its maximum speed, and the flame at the tail becomes smaller. The missile's engine reduces the fuel consumption speed, allowing the missile to enter the cruise phase.
For ordinary missiles, all fuel will be consumed within ten seconds, and the rest of the time is the unpowered flight phase. However, for ramjet missiles, there is no such lack of energy. The powered flight phase.
The reason is simple. These two rectangular air inlets cause the missile to experience greater resistance. Once it loses power, the speed of the missile will quickly decrease, and finally it will lose its speed. Therefore, this kind of missile cannot be without Power cruise, in this way, after the missile is accelerated to the maximum speed, it will cruise at this speed in the most fuel-efficient manner.
This also limits the long range of the missile. When the fuel is consumed, it means that the range has reached the end.
Of course, the range is actually closer because in the final stage, it will have more fuel left, which can be used as a high-overload maneuver of the missile, so that it can deal with the same target as a fighter jet.
The bulky Phoenix missile cannot deal with highly maneuverable fighters. In the final stage, the fighter can easily make the Phoenix lose its guidance through various escaping actions. For example, if one climbs up to get rid of, the missile must follow the climb. At this time, the missile has no power. It is completely flying by inertia and cannot keep up with the target's maneuvering, so naturally it cannot attack.
Therefore, no matter how high the missile's declared maximum overload is, such as 35G, which far exceeds the maximum overload of 9G fighters, in reality, it is completely possible for fighter jets to get rid of missile attacks. The key depends on the pilot's skills.
Use a map to show the flight envelope of a missile. The area enclosed by each map is the inevitable zone of the missile. Only in this area can there be a high enough hit rate, which is not 100%.
However, for the current Pili-13, the engine has been used, especially in the final stage, the engine will burn at full speed, so its inevitable zone is much larger than the original Pili-12 missile!
How against the sky? The total working time of the missile's engine is more than one hundred seconds, and the near-end inevitable zone is about 100 kilometers, that is to say, within one hundred kilometers, there is almost no running! It used the second engine power to create the envelope of the sky-defying no-escape zone. This kind of lethality is the favorite of the pilots who use it.
Especially, if the early warning aircraft is hunted down, it will be easy to come by. The kind of aircraft carrying a large plate has very poor maneuverability and is born to be a target.
In fact, Chen Rui is now able to return home. After all, the missile he launched is an active missile. He relies on inertial flight in the first half of the flight, and actively seeks targets in the second half. However, Chen Rui is still staring, he is expecting his first Time knows the result. This is an attack from a hundred kilometers away. Even the Phoenix missile has a range of more than one hundred kilometers. In actual use, it is only an attack at a distance of 70 or 80 kilometers. The current range is absolutely real. Yes, there is no discount, this missile will become the killer of your own aviation!
On the goggles of his helmet, the data continues to be displayed. The current data is calculated by his own radar, which shows the distance between the missile and the target.
One hundred kilometers, eighty, sixty, forty, when it was twenty kilometers, the seeker of the missile successfully found the target!
The J-5 UAV is flying steadily. It does not know that it is currently on a one-way voyage, and it is destined to have no future. It is flying for the last time. At this time, the missiles in the distance have already been launched to its death. The beam, the electromagnetic wave of the monopulse seeker, completely enveloped it.
Speed ​​up, speed up! After discovering the target, the missile’s computer knows that the internal fuel is sufficient after a simple calculation. Therefore, the missile starts to accelerate and the power of the tail engine reaches the maximum, and the hot flame is ejected backwards in the sky. Diffuse thick trails.
The distance is approaching rapidly, ten kilometers, five kilometers, and one kilometer. In the final stage, the proximity fuze continuously measures the distance between the two sides. When the distance reaches 15 meters, there is a loud bang, and the missile’s ring is broken. The pole warhead exploded, and these warheads linked into a ring quickly spread outwards, forming a rain of death, and soon had close contact with the J-5 UAV.
The broken rod smashed into the aluminum alloy skin, and at a speed of several Mach, it easily tore the oxidized aluminum alloy skin, and got into it. Several pieces got into the engine, and some He got into the fuel tank, and then the plane turned into a fireball in the sky.
success!
The long-range attack of the Pili-13 accurately hit the target. This new type of missile, which is a perfect replacement for the Phoenix missile, has passed the target test flight, showing its combat effectiveness. Since then, the Han National Aviation Armory has more A killer!
