Chapter 1203

"If we copy the problem of artillery, the biggest obstacle is the ammunition supply system. We will certainly solve this problem by carrying forward the spirit of not afraid of hardship and not afraid of death." director Yang said: "however, there are other problems in our artillery research and development."

One is not afraid of hardship and the other is not afraid of death. There is nothing wrong with this. When developing artillery, we often risk our lives. In case of an explosion, there will be no people.

Now the one armed chief engineer of domestic tank research and development lost his arm because of the accident?

We must overcome all kinds of difficulties and complete the R & D of this project!

Qin Guan nodded: "yes, another problem is the fire control system. We can ask brother units to help with this system."

An infantry machine gun can be aimed with the eyes. However, when it comes to warships, artillery has gun aiming radar, and only radar can keep up with incoming missiles.

The higher the speed of the incoming missile, the faster the response speed of the fire control system. Especially now, the close defense gun is the last defense barrier of the warship. Once the interception fails, the warship will be in great danger.

Therefore, it must have an advanced fire control system. Now, domestic electronic technology is developing rapidly. Even so, the indicators proposed by this project are greatly beyond their ability.

According to the design scheme proposed by Qin Guan, a set of comprehensive detection equipment combining white light camera, infrared thermal imager and laser rangefinder is installed on the right pillar of the system, and a small-diameter centimeter wave fire control radar is installed on the left.

Technical requirements: the detection distance of small targets is 8km, the detection distance of large and medium-sized targets is 15-20km, and the photoelectric system can detect targets within 6km.

In this way, if the electromagnetic interference is not very strong, the fire control radar will be used for tracking. Once the fire control radar fails, it will turn to optical tracking at any time.

We mainly rely on white light cameras during the day and infrared imagers at night. These advanced technologies sound like science fiction films to everyone.

Who could have thought of using optical control? No one, all controlled by computers?

Under the control of fire control radar and photoelectric tracker, 730 naval gun has the ability of multi-target tracking and reconciliation, can track and attack multiple targets at the same time, and can intercept missiles with a speed of less than Mach 2. The maximum interception distance to aircraft targets is 3500 meters, and the maximum interception distance to missile targets is 2500 meters. At a dense rate of fire, any enemy will be screened.

That's a good theory, but who can do it?

What kind of infrared imager? I'm afraid there is no unit in the country.

Qin Guan knew that his index was somewhat high. Infrared technology developed with the development of night vision instrument. In the early days, it was low light level night vision instrument, but now it has gradually transitioned to infrared imaging night vision instrument.

Due to the huge volume of the infrared imaging system, it was used in industrial, medical and other fields in the early stage. Until the 1980s, the infrared focal plane array technology developed to realize infrared imaging through the receiving unit of the array. The largest fotric228 has realized 640 * 480 pixels, which is just enough.

In addition to this imaging technology, computer software for image processing also began to develop, which laid the foundation for the development of infrared imaging system.

But now, these are really blank in China. It is said that infrared capture can be used to guide our naval guns. Everyone is like a arabian night.

"We'll study the radar version first," Qin Guan said. "For the radar version, 114 institutes can be invited to assist. With their help, we will certainly complete the research and development soon. We will also provide certain materials. After the research and development is successful, we will follow up the research and development of this kind of optoelectronic equipment."

The photoelectric aiming device is really difficult, so it's difficult to get on the radar first. Anyway, the export models are reduced in grade. I didn't say the detailed parameters of this near anti gun in the export contract. I didn't even make it clear whether 7 tubes or 11 tubes.

With the complexity of the electromagnetic environment, this photoelectric aiming indeed has great potential. Once disturbed, it will turn to optical aiming at any time. However, at the same time, the research and development of this system is difficult and the cost is high.

It can be said that if such a system is installed, the warships sold by themselves will simply lose money.

For example, in later generations, the cost of the standard 730 naval gun is as high as 100 million Han dollars, and the purchase price is even higher. This price is absolutely shocking. It can be said that if the national economy is not good, even if it can be developed, it can't afford to be equipped. In order to make this system enter the international market, a low configuration version of 730 naval gun was developed. The self-use version was changed to a fire control system to control the distribution design of two guns, which reduced the cost and was specially used for export.

Qin Guan lowered the requirements for everyone and made the radar version first. In this way, the difficulty of development immediately came down.

Director Yang said: "if we only study the radar version and have 114 institutes to assist, we guarantee to complete the task!"

Now, he is finally full of confidence. The obstacles have been solved one by one.

"Director Yang, there is another major problem that you need to overcome," Qin Guan said solemnly at this time.

There's another big problem!

What's the problem? Everyone was stunned.

"Servo system, you don't have to be afraid to spend money. You must choose the best quality," Qin Guan said.

The proximity gun will be an independent combat module. As the last interception system of the warship, it can also complete the task in case of the failure of the warship's own fire control system. Therefore, it is not cross-linked with any other system, and it is completely on its own. Search the radar to find the target → quickly turn the muzzle → track the radar to accurately aim → fire → track the radar to keep tracking and measure the error → correct the aiming → continue to fire and cover the target route → the target is hit.

This procedure needs to be completed in a very short time. Among them, turning the muzzle of the gun is a hard work.

After all, this thing is very heavy, integrated together, often several tons.

Our own has not been developed yet. It is not clear. Take the "dense array", which weighs 7 tons. When adjusting the gun, the maximum angular velocity exceeds 100 degrees / second and the maximum angular acceleration can reach 450 degrees / square second. So heavy, but also so fast emergency stop and turn, to accurately point the gun to the target, the quality requirements of the motor servo system are not the highest, only higher.

Now, the people present did not think of this problem, but Qin Guan clearly knew that gun barrel and fire control were secondary. This servo system was the most tangled.

The artillery turns slowly, so it can't meet the actual combat requirements. Although c801, which is powerful on our side, is a subsonic missile, Xiong's is all supersonic.
