Bright Sword Military System

Chapter 531 Majors
Colonel Perris is the section chief of Eagle Sauce's National Defense Technology and Research Bureau. He is responsible for the research and development of air defense equipment... This is the characteristic of Eagle Sauce's armament research and development. They always think that professional things must be done by professionals, so that they can be done well He is better than others, so Ying Jiang's research subjects are very detailed.

Colonel Perris had always believed this, but today it made him feel otherwise.

Because an ordinary officer in Huaxia, who is said to be just a battalion commander, proposed a concept that is much more professional than professionals like them...proximity detonation fuze.

At this time, Colonel Perris's research institute was busy, and the subordinate researchers were urgently collecting information and drafting a research and development team for new anti-aircraft artillery shells... Obviously, this kind of fuze requires the cooperation of talents in both radar and shell design.

Assistant Davis rushed over and said: "Colonel, many people think this plan is not realistic. We haven't miniaturized the radar yet, but now we have to stuff it into the fuze of the shell! What's more, the cost of radar is high. The cost of shells is likely to be several times or even ten times that of ordinary shells..."

"I know it costs more, Major!" Perris interrupted Davis as he quickly signed the document: "But it's just a matter of cost? Do you think it costs more than ten times that of ordinary shells? Meaning we can replace it with a dozen normal shells?"

Perris handed the signed document back to the adjutant, raised his head and said to Davis: "No, Davis! You also have to consider the time loss on the battlefield. The hit rate of ordinary shells is only one in two thousand. If This kind of shell can increase the hit rate to one in a thousand, which means we have succeeded. Because our warship is likely to be hit by the bomb of the enemy plane before firing two thousand shells, but we used this Plant the fuze and have time to fire a thousand rounds and blow it to pieces!"

Speaking of which, Perris took a step closer and looked directly into Davis' eyes: "Now, try to calculate the cost and tell me the answer!"

(Note: The hit rate of the measured proximity fuze has increased by four times, that is, an average of 500 shells can hit one)
The answer is obvious. Perris is right. Time on the battlefield is far more important than the cost of shells, especially anti-aircraft shells.Because enemy aircraft often bombed valuable targets, time at this time properly represented life and wealth, and its value was much higher than that of artillery shells.

Perris even believed that if the eagle sauce had developed this shell earlier, the battleship Arizona would not have been sunk by the Devils at Pearl Harbor, and there would have been no casualties of more than 3000 people.

However, just like all advanced equipment will be questioned, many people object to this innovative new shell. They think that the shell should be a quantitative thing. Instead of spending a lot of money to develop this shell, it is better Add a few more guns to the air defense force or train the quality of the gunner.

Perris shook his head lightly, secretly thinking that this group of short-sighted guys are not even as good as a battalion commander of the Chinese Eighth Route Army.

Davis seemed to be convinced by Perris's words, but he pushed his glasses and asked again: "So, the issue of radar miniaturization..."

"Tell me, Davis!" Perris interrupted Davis again. "How long does it take for a shell to reach its target?"

Davis froze for a moment, and replied: "I'm not sure, Colonel! Half a minute, or 1 minute!"

Davis estimated the muzzle velocity and range of the anti-aircraft gun. For example, the M1 anti-aircraft gun has a range of 19 kilometers and a muzzle velocity of 823 m/s. It is easy to conclude that it only takes 23 seconds for the shell to complete the range.

But because this is the initial velocity, it will gradually slow down due to the influence of air resistance when flying in the air, so it takes about half a minute.

Perris asked again: "So, what is the killing radius of the anti-aircraft gun?"

"About 30 meters!" Davis replied.

(Note: The killing radius of shrapnel to people is different from the killing radius of fighter planes. Shrapnel has lethality to people from 50 meters away, and the killing radius of large-caliber shells can even reach [-] meters away, but this is not the case for fighter planes. But not necessarily, for example, if an anti-aircraft gun explodes in front of a fighter plane, the shrapnel will be much more powerful if it goes towards the fighter plane)
Perris nodded: "In other words, the radar we need only needs to work for about 1 minute, and the power can detect about 100 meters..."

"100 meters?" Davis asked in surprise, "Why 100 meters?"

He can understand it after working for 1 minute, but if it can only detect 100 meters...

"You idiot!" Perris explained, "It doesn't need to catch the target the moment it shoots out of the barrel. Our anti-aircraft guns will fire many shells towards the target. Some of these shells can enter the range of [-] meters of the enemy aircraft and others cannot. Anything over [-] meters It’s not a problem we need to consider, because it can’t pose a threat to the enemy machine whether it explodes or not, but once the shell enters the range of [-] meters, the fuze radar can play a role, understand what I mean?”

Davis now fully understands that the detection range of the fuze radar really only needs to be 100 meters, because after it is launched, it is actually searching for a target within 100 meters of itself instead of locking on to the target more than ten kilometers away... If it is required to detect targets more than ten kilometers away like ordinary radar, it cannot be small enough to fit into the fuze.

Therefore, this kind of radar only needs to work for 1 minute, and the detection distance only needs to be 100 meters. Miniaturization is indeed not difficult.

"Of course!" Finally, Perris added: "It should have a self-destruct function!"

Davis nodded in understanding.

In the unlikely event that no target enters its 100-meter range and it fails to detonate, the shell may fall back to the ground and be acquired by the enemy, which the military does not want to see.

"So!" Perris finally came to a conclusion: "Don't waste any more time on this issue, what we need is to make this thing, the sooner the better!"

"Yes, Colonel!" Davis replied.

At this time, a communication soldier came forward with a telegram and reported: "Colonel, the telegram from Huaxia, they asked to modify a Bofors mounted on a tank chassis! Captain Wilson wanted to know if this equipment is meaningful to us !"

Perris took a glance at the telegram, imagined this kind of equipment in his mind, and said to himself, "Bofors mounted on a tank chassis? Interesting!"

Then it suddenly thought of something, opened the map and marked the devil's attack point according to the information, then raised his head and said: "God, this is also the equipment we need! He actually thought of us! Is this a coincidence? Or On purpose?"
