Chapter 175 Long-distance dynamic and static target shooting
Moving versus stillness is very difficult.
A slight bump makes a thousand miles difference. For the tank gun here, a slight bump caused a slight vibration at the muzzle. When the gun went out, it only changed a small direction angle. After it went out, it was completely fired.
Crooked.
When the tank is moving, bumps are always present. If this bump cannot be eliminated, it can only fire when it is stationary.
If you want to maintain the stability of the muzzle despite the bumps of the vehicle body, you need a two-way stabilizing platform.
In other words, the tank gun is independent of the vehicle body. No matter how the vehicle body changes, the tank gun can remain stable. For a tank that can only maneuver on the ground, as long as the direction stability and pitch stability are ensured, the tank gun can remain stable.
Enough, this is called a bistable system.
You can often see videos of some advanced Western tanks. The body of the tank is galloping and bumping constantly, but the muzzle is as steady as a mountain and does not move at all. Or, the tank body turns on the spot, but the muzzle keeps aiming at the target. Even
Put a goblet on the muzzle and it will stay stable.
It seems mysterious, but the principle is actually not difficult. It is equipped with a series of electronic devices. When the tank bumps, the gyroscope can quickly sense the attitude change of the tank, and then convert this change into an electrical signal through the sensor and transmit it to the computer.
, calculate the compensation amount, compensation direction and compensation angle, and then perform motion compensation through the servo system of the turret. In this way, when the vehicle body moves, the internal system continuously compensates, and the muzzle can be kept aligned with the target.
Only in this way can you fire while in motion, because then it will be no different from firing while stationary.
The West has long been proficient in this system. Not only the Chivotan tank, but even its previous model, the Centurion tank, already has a complete bi-stable platform.
However, this technology does not exist in China. Until now, all domestic tanks can only stop and shoot. The 59 tank does not have a bi-stable platform and only has a pitch stability. The 69 tank is said to be bi-stable.
Platform, but, haha...
Of course, the bi-stable platform is only a prerequisite. The bi-stable platform only means that the muzzle will not change with the bumps of the tank. If you want to hit the target, you need a complete set of advanced fire control equipment.
When the original optical sighting system was still used in China, the Chivotan already had an advanced fire control system of this era. It included four subsystems: the data control subsystem, including the Marconi 12-12P digital computer.
, commander's control and monitoring device and shooting handle; aiming subsystem, including tank laser sight and aiming electronic equipment; sensor subsystem, including wind speed, wind direction, temperature, air pressure, gun trunnion tilt, sight mounted on the tank
Angle, charge temperature, bore wear, target movement angular velocity and other sensors; electronic processing equipment subsystem.
How advanced is its fire control system? After every firing, the gun barrel will be worn, and even this error can be taken into account. Therefore, the accuracy of this fire control system is quite high.
According to the British idea, they intend to kill the enemy at a long distance. With this 55-caliber 120mm tank gun, they can even kill Soviet tanks at a distance of four thousand meters. On the contrary, Soviet tanks are estimated to be
You have to rush within a thousand meters to have a chance to destroy the British tanks.
However, only long-range tank guns are not enough. They must have a matching fire control system. Therefore, the fire control system of their Qifutan is also quite good. In actual shooting, stationary targets within three thousand meters can be
, moving targets within two kilometers have high accuracy.
Just now, several people in Qifutan were preparing carefully. Wang Erzhu pulled out the training ammunition and stuffed it into the gun barrel. Qin Zhenhua used the commander's sight to indicate the fixed target three thousand meters away. Li Changjiang
Aim carefully, bind various data, until finally stepping on the trigger.
"Boom!" With the roar of tank guns, several people held their breath for an instant.
Driving a tank looks very majestic, but is actually very difficult. Especially once the gun is fired, black smoke will spread outside the muzzle. In fact, the inside of the tank turret is similar to the outside. A black smoke will permeate the entire turret. It is better.
After a while, it will be sucked away by the fan in the turret.
They are all experienced.
But now, when they held their breath, they discovered that the black smoke that filled the turret was almost nothing! At the moment of firing, the smoker in the middle of the barrel had been completely smoked out!
"This is called a tank." Li Changjiang couldn't help but sigh when he found that there was no gunpowder smoke. Although the roar of the engine at the back was still coming, compared with the domestically produced 59 tanks, the noise was much smaller, so it was still OK.
communicative.
After driving Western tanks, you will definitely be disgusted with the backward ergonomics of your own tanks. It is very comfortable and convenient here, and it is of great benefit to improve the combat effectiveness of tankers!
"Zhenhua, shall we go back now?" Zhang Xiangyang from the front sent a question through the intercom in the car.
Now, the cars are racing and the cannons are firing, so it’s time to go back, right?
"If there is still more fuel, let's go for another lap. It won't cost any money anyway." Qin Zhenhua said happily.
For this time, everyone has practiced for a long time. In the maintenance workshop, we found some cardboard and marked out the internal equipment of various types of tanks that we were about to come into contact with. We practiced hard. Just after getting on the vehicle,
I started to get used to it, so now, it is reasonable to have such an effect.
"I don't know if I hit it or not." Wang Erzhu muttered, "That's a target at a distance of three thousand meters."
The mobility has been tested, but the accuracy of this artillery fire is still unclear. After all, our side has never experienced firing at a target at a distance of three thousand meters.
By the way, that laser rangefinder is really easy to use! It directly displays meters, which should be 3150 meters. If it is so far away, if you can hit it, you will be very lucky, right?
"It should be no problem. Their tank was originally meant to be displayed to us." Qin Zhenhua said: "It must have been calibrated in advance. I can't say for the second shot. The accuracy of the first shot will not be low."
"What if we make a mistake?"
"Why are you so unsure? If you miss, it must be because their equipment is not good. Our operation is absolutely top-notch!" Qin Zhenhua said firmly. At this time, as the body of the tank was still bumping, Qin Zhenhua opened the
If you lift the hatch cover above your head and expose half of your body, you are called a lafeng, a lafeng who eats ashes.
