Qin Feng's gaze looked at it, and what attracted his attention the most was that angle, twenty degrees!

When I was in Dassault, I saw that the R550 missiles they carried, the off-axis launch angle reached eight degrees, and everyone was already very excited at that time, compared to the domestic 1.5 degrees off-axis launch angle, this is a huge leap, and Qin Feng also tested the air combat subject, at that time Qin Feng experienced the benefits of this missile, in flight, lock the enemy, it is too easy to attack!

At that time, it was only an octave off-axis launch angle, and now, the off-axis launch angle of this missile has reached twenty degrees, what does this mean? As long as you push the lever slightly, you can make the missile achieve the ability to lock on to the target and attack!

In the Bekaa Valley, everyone has seen how the Israeli Air Force abused the Syrian Air Force, and at that time they were very concerned about this air-to-air missile, and they also used to calculate its performance, and now when they see the real data, they know that the Israelis are not lying, it can really achieve such capabilities!

"In the future, if the technology is further developed and an off-axis launch angle of 90 degrees can be achieved, then the battle will be easier." At this time, an expert in the same industry couldn't help but come up with such a sentence.

Hearing this, Qin Feng shook his head: "It's not like this, when a fighter launches a missile, it still has to give the missile an initial velocity, if it is launched at 90 degrees, then it will not be able to give the initial velocity of the missile, and the range of the missile will be greatly shortened." ”

Now the other party's explanation has not officially begun, everyone is just sitting down, Qin Feng said this, suddenly, that Ike actually showed a smile of approval on his face, this person understands Chinese, although he is not very fluent, but there is no obstacle to basic communication, Qin Feng's analysis is also their own analysis of future air battles.

In the past, missiles had to be launched at the rear, so there was no off-axis ability, but later, this angle became larger and larger, and designers worked hard to pursue this angle, does that mean that the bigger the angle, the better?

This is not the case.

For example, when the carrier aircraft reaches Mach 0.9 when the missile is launched, the missile will initially have an initial velocity of Mach 0.9, and the missile will start to accelerate with its own engine, and it will be easy to accelerate to the maximum speed of Mach 2.5, for example.

However, if the large off-axis launch, such as the limit, is 90 degrees, then the missile does not have any lateral velocity, and the missile has to rely on its own energy to complete this acceleration from 0 to Mach 2.5.

It can be said that the larger the off-axis angle, the smaller the range, or inescapability, zone.

Of course, this is not the case, because when the missile is launched, it is still launched forward, but after the launch, it needs to be turned at a large angle, which will seriously consume the energy of the missile and greatly shorten its range.

In short, this is not the bigger the better, at least in the current power situation of the solid rocket engine, forty-five degrees, or sixty degrees, is already the highest, if there is an anti-sky propellant in the future, then raise it to ninety degrees, or even one hundred and eighty degrees, and attack the aircraft behind.

However, everyone still noticed that the most important parameter of this missile is the maximum off-axis launch angle of 20 degrees, which is the most advanced place of this missile.

In air combat, the pilot's chances of firing are greatly increased.

Ike cleared his throat and said, "Okay, now I'll introduce you to our missile, and I'll follow this picture and explain it to you in turn." ”

In appearance, this missile is very similar to the AIM-9L, with a canard aerodynamic shape layout, divided into two sections: the front compartment is equipped with a seeker marker, electronic components, a thermal battery, a nitrogen cylinder and an active radar proximity fuse; The aft compartment houses a warhead, a safety actuator and a rocket engine.

"Alright, let's go separately." The second slide is on top of it, and it's the front compartment.

"We know that the performance of a missile depends mainly on its seeker, and only if the performance of the seeker is high enough to achieve its detection capability, for example, if it is fired head-on, a more sensitive seeker is needed." "We use a Cassegrain optical system and a proportional guidance law for this seeker, an indium antimonide infrared detector, and to achieve good results, we use nitrogen cylinders for cooling," says Ike. At the same time, the electronic components are made of thick/thin film circuits that are solid-state miniaturized. ”

The front part of the missile is the seeker, and behind the seeker, there is the warhead.

Different weapons, warheads are different, for example, to fight a tank, you need a hard and slender armor-piercing bullet or shaped warhead, and when you fight a plane, what you need is fragments, as long as a fragment collides with a high-speed flying fighter, you can open a big hole.

Therefore, the warhead of the air-to-air missile is like this, and there are more than 2,000 steel balls in the warhead of the Monster Snake-3, forming a backward flow of fragments, forming a dense rain of death, as long as the fighter flies within its killing radius, it will collide with it, even if a steel ball hits the fuel tank, it will definitely cause a fire.

Behind the warhead is the proximity fuze, which has been developed since World War II and has now been improved to a very high level of accuracy.

A pair of receiving/transmitting antennas of the proximity fuze are installed on both sides of the outer body of the missile body, providing a detonation signal according to the Doppler frequency when the missile flies over the mesh, with strong anti-interference ability and a fuse action distance of 10 meters.

Listening to each other's introductions, compared with their own missiles, almost every aspect has improved, and almost all of them are at the top level of this era.

Then, there is the rear projectile body.

Behind the missile body, there is a two-stage thrust solid rocket engine, which allows the missile to reach a maximum range of 15 kilometers, with a minimum range of 500 meters, and the rolling stable gyroscopic rudder on the trailing edge of each projectile wing reaches 10,000 revolutions per minute under the action of aerodynamic forces.

(If you look at the air show or photos, whether it is a model or a real missile, you only need to look at the place where the wings are located to see if there is a gyro rudder.) ）

The three pictures Ike took more than twenty minutes to introduce them, and the last picture is its overall parameters.

Overall mass, one hundred and twenty kilograms!

When I saw the weight of this missile, some people immediately muttered, this missile is too heavy, right? Can our fighters be mounted?
