Chapter 251: Cannon attack

When flying the simulator, you can fly as you want. There is no psychological pressure. If the plane crashes, a fire appears on the screen, and then a red eye-catching headline reminds that the plane crashed and the personnel died.

It's just a game, how can there be pressure to play a game?

But now, that’s a real machine, the game can be played again, and the simulation can start again, but if the real machine is flying, there is only one chance.

Open a real machine, like a simulator, this kind of psychological quality is not something ordinary people can have.

Chen Rui came to the fore from the live ammunition shooting.

"061, pay attention to flying height." At this moment, a voice came from the headset.

The distance between the base and the exercise area is only a few hundred kilometers. The large radar vehicle deployed in the base can see Chen Rui's flight trajectory. Now that Chen Rui is lowering his altitude, he is immediately alerted.

How to do? Chen Rui was also embarrassed at this moment.

A soldier, it is his duty to obey orders. If he requests a dive attack, he will definitely be rejected. Now, the order prohibiting a dive attack has not come down. He simply...

With his right hand skillfully flipping the switch on the right operation panel, Chen Rui turned off the radio.

Well, I unconsciously touched the radio switch and turned it off. In this way, I couldn't hear the command. I couldn't hear the command. Of course, it was not a resistance order.

On the front instrument panel, the altimeter's analog display pointer is spinning fast, and every time it rotates, it means that it drops a kilometer in height, and after five turns, the height is zero.

In fact, the altitude is of course not zero. The most commonly used barometric altimeter is not very accurate and has errors. Now, Chen Rui can rely on his naked eyes.

His eyes were staring at the HUD. At this time, there was a line flashing on the HUD. This was the hotline of the machine gun that made him amazed.

It is not easy to hit pao in the sky.

Air combat began before the invention of the aircraft, and the original weapon was a machine gun. After that, the machine gun had insufficient power and increased its caliber to become a machine gun.

Whether it's a machine gun or a machine gun, in short, if you want to hit the target, you must aim, and this aiming is more troublesome than on the ground.

Because it is three-dimensional and the target is still maneuvering, in order to accurately hit, a series of special sights are needed.

This is the active halo sight.

The principle sounds uncomplicated. It relies on the light of the illuminating lamp to pass through the condenser tube, through the overlap of the shading sheet and the engraved line of the ring plate group, to form a halo composed of prismatic light spots and ring centers; The gyro mirror and mirror reflect on the objective lens for magnification and then project it onto the sight. The pilot sees the sighting halo and distance number through sighting.

However, it is quite cumbersome to use. First of all, this thing needs to be preheated for at least 3 minutes to heat up. Then, you must visually identify the target model and turn the wingspan **** based on the data in your memory. The wingspan scale is selected so that the distance measurement can be completed. The basic principle is the perspective principle.

Next, move the ring selector lever to the active halo position; press the ring stabilizer button to make the halo closely follow the motion of the machine; turn the rangefinder handle to enlarge the halo; estimate the elevation angle and advance angle, and place the halo above the target , Loosen the ring button, shrink the halo, the halo moves backward and downward, and the center light spot slowly falls on the target...

Can this fire? It's still far!

This is just preparation work, just like a warm-up exercise. Next, there are decisive precise targeting steps: "follow", "wrap", "stable".

The specific principle is no longer mentioned. In short, this set of movable halo sights is the main aiming device of ordinary aircrafts. At the same time, it is also quite cumbersome, and it is simply intolerable.

The pilots of the Eagle Country, the Prime Minister could not bear it, and urged the country to develop a new type of aiming method called hotline aiming based on electronic computers, head-up displays, and radar.

As the name suggests, it has a line, and this line is calculated by an electronic computer.

Taking into account the conditions of the fighter aircraft in various states, including altitude, speed, angle of attack, sideslip angle, pitch, slope, initial velocity of the warhead, ballistic coefficient, etc., in this way, the computer can calculate each gun fired. The impact point of a shell relative to the position of the machine is calculated and connected into a dynamic curve, which is displayed on the head-up display.

This hotline is correct regardless of whether it fires or not. The starting point of the hotline is a cross, representing the muzzle, and the farthest point corresponds to the maximum range in the sight design.

In other words, before I fired, I knew where the shells would hit. As long as the target's trajectory coincides with my own hotline, I can hit it.

Compared with the previous series of cumbersome steps, it is now much easier, and the same is true when attacking the ground!

Now, the hot spot in front of the hotline coincides with the target. As the distance gets closer, the target is getting bigger and bigger. At the beginning, it was just a point. Now, the shape of the bomb is clearly visible.

One thousand meters, eight hundred meters, six hundred meters...Just five hundred meters away from the target, Chen Rui pressed the button on the joystick.

"Tom Tom Tom!" In an instant, the 23-3 double-barreled 23mm caliber machine gun at the belly of the aircraft opened fire violently.

A burst of flames emerged from the muzzle of the machine gun. A few meters away from the flames, there was dense smoke. In front of the dense smoke, 23mm artillery shells rushed forward with a tiger descending the mountain!

The cannons of fighter aircraft have not made much progress over the years. At the same time, in order to shoot into the air, it is usually high-explosive shells. Between several high-explosive shells, there is a tracer armor-piercing. Incendiary.

Generally, the shell of aero ammunition is made of steel. Therefore, the 23mm high-explosive bomb is not very effective against the shell of the aero bomb. What is useful is the armor-piercing incendiary bomb.

Although it was daytime, the white light pulled out by the tracer could be seen. From the eyes of people in the distance, this fighter had too many mysterious places.

Attacking from this angle, how accurately the pilot can aim? That bright line was almost directly facing the aerial bomb. This highly skilled pilot wanted to use the cannon to detonate the aerial bomb!

In the army, once a dud bomb appears, it must be eliminated by engineers and moved to a safe place to detonate it. The most common method of detonation is to fire at the dud bomb.

"Boom!" At this moment, this aerial bomb was finally detonated. In the explosion, a fireball rose into the air and rolled toward the dive-strike plane!
