Bright Sword Military System

Chapter 1324 Integration
In the end, Wang Xuexin did not let Ban Haolin and Chen Jiefeng do many experiments. Wang Xuexin directly gave the most suitable data for the mercury tube: diameter 10MM, length 1500MM.

Even Wang Xuexin gave the overall design drawing: 100 such mercury tubes are fixed in a cylinder like a concrete mixer and rotate continuously.

The reason for continuous rotation is that the performance of the mercury column is the most stable at 40 degrees and it is not easy to lose the signal. Therefore, the temperature of the cylindrical tube must be maintained, and the rotation is to make the internal mercury tubes heated evenly. Each tube is at about 40 degrees.

The data and design given by Wang Xuexin surprised Ban Haolin and Chen Jiefeng, because they made the memory according to what Wang Xuexin said, and found that the sound wave passing time was exactly one second, and the performance was very good at 40 degrees. Stablize.

The answer given by Wang Xuexin is: Huaxia has other R&D teams besides you. They have already tested the mercury tube and obtained these data.

This once again made Ban and Chen very excited... The sun never sets still uses paper tape and relay storage, but Huaxia has successfully used mercury delay line memory, and it's not just a team, which is obviously more than Japan. Not falling and exceeding not a little bit.

There's nothing wrong with their thinking.

If this kind of mercury delay line memory can store 1000 bits per mercury tube, 100 tubes can store 10 bits, that is, the data that can be stored in such a simple device is equivalent to 10 relays or electronic tubes. No matter in terms of economy, speed, volume, weight or reliability, mercury delay line memory is much higher than relays and electronic tubes.

But even so, this kind of memory still weighs a ton... Mercury has a high density, so it looks small in size but heavy in weight.

So Wang Xuexin had to think about a question:
Does the gun detection radar need to carry a ton of memory on the battlefield?
If just the memory weighs a ton, how much does the entire computer weigh?

Is it suitable to carry a computer of this weight on the battlefield?

So Wang Xuexin immediately gave Ban and Chen a new task: use electronic tubes to design a special computer for gun detection radar, and minimize the required storage space and storage units.

This is why programmers should consider "space complexity" when writing programs.

Considering the "space complexity" of modern programs does not actually make much sense, because modern memory is always as many as G, and the amount of memory that a small program needs to occupy in it is almost negligible, and it doesn't matter if it is more or less.

But computers in this era are different.

In the case of relay or tube memory, each bit of storage space takes up a relay and memory.

Although the mercury delay line memory is much better, but considering that it needs to be as light as possible to go to the battlefield, the storage space should be reduced as much as possible.

As for the program... because the calculation steps of each gun detection radar are the same, they all input three coordinates, each of which has three numbers, which are longitude, latitude and altitude, and then calculate the trajectory of the parabola based on these data and then compare the numbers The data comparison of the map finally obtains the coordinates of the enemy artillery positions.

The so-called "program" of computers in this era is the rules of wiring.

Since the calculation methods are all the same, the program of the gun detection radar is the same, that is, the wiring rules of all gun detection radars are the same.

So Wang Xuexin suggested that Ban and Chen directly fix these wirings and package them instead of being pluggable like a computer... The pluggable design of the computer is to facilitate the writing of different "programs", and the gun detection radar only needs one "program". ", so the pluggable function is redundant.

Doing so can further reduce the weight and volume of the calculation part of the gun detection radar.

At this point, the problem of gun detection radar is almost solved.

The reason why I say "almost" is because equipment is not just a matter of solving theoretical problems, but it must be done in the end. After all, things like "the ideal is very rich and the reality is very skinny" happen from time to time in equipment.

But this is not what Wang Xuexin needs to consider, he can only try his best to make every move well.

After having the artillery detection radar, it was the problem of the artillery. Wang Xuexin didn't think much about it, and contacted Lemon Lokoff immediately.

At this time, it took Lemon Lokov a lot of effort to get to Liyuan.

The reason is that the stubborn army is fighting fiercely with the devils at this time, and the airspace of the stubborn army is full of devil's planes, even the sky over Chongqing is no exception.

Under such circumstances, it is very dangerous to take a plane from Chongqing to Liyuan, and the recalcitrant army has a great demand for aircraft during the battle. It is difficult to transfer a special plane to Lemon Lokoff, but Lemon Lokoff still wants to The method took off at night and arrived in Liyuan in the early morning of the next day.

For Lemon Lokov, this risk is worth taking, because every time he goes to Liyuan, he gains a lot. If it is not for the opposition of the recalcitrant army, he even plans to stay in Liyuan for a long time like Eagle Sauce so that Keep in touch with Wang Xuexin.

As soon as Lemon Lokov walked into Wang Xuexin's office, he warmly hugged Wang Xuexin: "My friend, as you guessed, Hans really divided his troops into two groups to attack the Baku oil field and Stalingrad, because there are You reminded us that we have prepared in both directions, and the sneak attack that Hans thought he did not get any benefits!"

Wang Xuexin was a little strange when he heard this. He asked: "Hans thought he didn't get any benefits from the sneak attack? Comrade Lemon Lokoff, why did you emphasize 'sneak attack'? Could it be that..."

Lemon Lokov sighed and nodded helplessly: "You are very smart, Comrade Commander! Yes, as you guessed, although we are prepared in both directions, the situation of the battle is still dire. Optimistic, it's hard for me to imagine what would have happened if we hadn't been reminded by you!"

Wang Xuexin was puzzled for a while.

It shouldn't be like this. In history, Hans has never won either in the direction of Baku or in Stalingrad. Now that Wang Xuexin has reminded them to prepare, shouldn't they have an advantage?Why is it still "not optimistic"?
Where is the problem?Could it be that Mao Xiong did something else to show off?

Seeing Wang Xuexin's puzzled expression, Lemon Lokov explained helplessly: "Originally, the situation of the battle was always favorable to our army. We fought well in defensive battles in both directions, but after more than a month since the battle started, Hans used a missile with a range of more than 200 kilometers, and the situation was reversed..."

Hearing this, Wang Xuexin was so startled that he almost fell over.

V1 missile?

This thing appeared on Hans' battlefield against the bear?
