Chapter 1203: Various problems

"The problem of the artillery, if we imitate, the biggest obstacle is the bomb supply system. We promote the spirit of not being afraid of hardship and not afraid of death, and we will definitely solve this problem." Director Yang said: "However, our artillery R&D, there are still other problems."
One is not afraid of hardship, and the other is not afraid of death. This is not wrong. The development of artillery is often life-threatening. In case of an explosion or something, people will be gone.
Now, the one-armed chief of the domestic research and development tank, his arm was lost because of the accident?
Everyone must overcome various problems and complete the research and development of this project!
Qin nodded his opinion: "Yes, another problem is the fire control system. With this system, we can ask brother units to help."
An infantry machine gun can be aimed with the eyes. However, on a warship, the artillery has a gun-sight radar, and only the radar can keep up with the flying missiles.
The higher the speed of the flying missiles, the faster the response speed of the fire control system is required. Especially now, the near-anti-guns are the last defensive barrier of the warship. Once the interception fails, the warship is in great danger.
Therefore, it must have an advanced fire control system. Now, the domestic electronic technology is developing rapidly. Even so, the indicators proposed by the current project are far beyond their capabilities.
According to the design plan proposed by Qin Guanji, a set of integrated detection equipment combining a white light camera, an infrared thermal imager and a laser rangefinder is installed on the right side pillar of this system, and a small diameter centimeter wave fire is installed on the left side. Control radar.
The technology requires that the detection range of small targets is 8 kilometers, the detection range of large and medium-sized targets is 15-20 kilometers, and the photoelectric system can detect targets within 6 kilometers.
In this way, if the electromagnetic interference is not very severe, the fire control radar is used to track, and once the fire control radar fails, it will switch to optical tracking at any time.
It mainly relies on white light cameras during the day and infrared imagers at night. These advanced technologies sound like science fiction films to everyone.
Who would have thought that optical control could be used? No one, relying on computers to control?
Under the control of fire control radar and photoelectric tracker, the 730 naval gun has multi-target tracking and resolution capabilities, can track and strike multiple targets at the same time, and can intercept missiles with speeds below Mach two. The maximum interception distance for aircraft targets is 3500 meters, and the maximum interception distance for missile targets is 2500 meters. At a intensive rate of fire, any enemy will be screened.
This theory is very good, but who can make 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 was developed with the development of night vision devices. The early ones were low-light night vision devices, but now they have gradually transitioned to infrared imaging night vision devices. .
Due to the huge volume of the infrared imaging system, it was used in industry, medical and other fields in the early days. Until the 1980s, the infrared focal plane array technology was developed to realize infrared imaging through the receiving unit of the array. The largest FOTRIC228 has been realized. 640480 pixels is pretty enough.
In addition to this imaging technology, computer software for image processing has also begun to develop, which has laid the foundation for the development of infrared imaging systems.
But now, these are really blank in China. I heard that infrared capture can be used to guide one's own naval guns, and everyone is like a fantasy.
"Let’s study the radar version first." Qin Guan said: "For the radar version, 114 can be invited to assist. With their help, the research and development will definitely be completed soon. We will also provide certain information until the research and development is successful. Later, we will continue to develop this kind of optoelectronic equipment."
The photoelectric sighting device is really difficult, so I got on the radar first. Anyway, the exported models are all downgraded. I didn't mention the detailed parameters of the near-anti-cannon in the export contract, even 7 or 11 tubes. Did not make it clear.
With the complexity of the electromagnetic environment, this kind of photoelectric aiming does have great potential. Once it is interfered, it can be switched to optical aiming at any time. However, at the same time, this kind of system is difficult to develop and costly.
It can be said that if such a system is really installed, then the warships that I sell will simply lose money.
For example, in later generations, the standard configuration of the 730 naval gun cost as much as 100 million Chinese yuan, and the purchase price is even higher. This price is absolutely staggering. It can be said that if the national economy does not work, it can be developed. Can't afford it. In order to allow this system to enter the international market, a low-profile version of the 730 naval gun was developed, and the self-use version was changed to a set of fire control system to control the distribution design of two artillery, which reduced the cost and used it exclusively. For export.
Qin Guan lowered the requirements for everyone and started with the radar version first, so that the difficulty of development would immediately come down.
Director Yang said: "If you only study the radar version and have 114 assistance, we promise to complete the task!"
Now, he is finally full of confidence, one by one, the obstacles have been solved.
"Director Yang, there is another major problem that you need to overcome." At this moment, Qin Guan said solemnly.
There is another big problem!
what is the problem? Everyone was taken aback.
"Servo system, don't be afraid of spending money, you must choose the best quality." Qin Guan said.
The near defense gun will be an independent combat module. As the last interception system of the warship, it can complete the task in case the warship’s own fire control system fails. Therefore, it will not be cross-linked with any other systems, it will be done by itself. . The search radar finds the target → quickly turns the muzzle → the tracking radar accurately aims → fires → the tracking radar keeps track and measures the error → corrects the aiming → continues to fire to cover the target route → the target is hit.
This procedure is to be completed in a short period of time, among which, rotating the muzzle of the artillery is a laborious task.
After all, this thing is very heavy, integrated together, it takes tons at every turn.
Our own has not yet been developed, so it’s not clear. Take the "Phalanx" as an example. This gadget weighs 7 tons. The maximum angular velocity during gun adjustment exceeds 100 degrees/sec, and the maximum angular acceleration can reach 450 degrees/square. second. It's so heavy, and it needs to stop and spin so quickly to accurately point the artillery to the target. The quality requirements of the motor servo system are not the highest, only higher.
Now, the people present had not thought of this problem, but Qin Guan knew clearly in his heart that the gun barrel and fire control were all secondary, and this servo system was the most tangled.
The artillery turns slowly, then it will not be able to meet the actual combat requirements. Although the C801 that oneself is currently playing is a subsonic missile, Xiong Guo's are all supersonic.
