Strictly speaking, Liang Yuan wrote this modified tank design document that was not formal at all, not only did it not write correctly according to the common design book format, but there were also a lot of scribbles.

Judging from some scribbled marks, those obscured naïve views verify that the owner of this design has absolutely not received any training in tank design.

However, Zhu Yusheng read such a messy and immature document with relish, and each page turned very slowly.

At the beginning of the design, Liang Yuan directly wrote down his main thoughts and cognitions of the tank shell transformation project, and all technical means are to serve the core thinking of the design at the beginning.

Liang Yuan didn't demonstrate the knowledge of firepower, communications, maneuverability, etc., and directly defined the core of his idea on the comprehensive protection and survival of tanks.

Liang Yuan wrote down his perception of the tank protection system very bluntly:

1. Try to avoid being discovered.

Prevent the vehicle from being detected by enemy radar, thermal sights, or optical devices.

2. If you are spotted, try to avoid being hit.

Vehicles should be equipped with equipment for the formation of suspended shielding smoke screens and jamming, and should have the ability to confuse enemy laser-guided or infrared-guided anti-tank missiles and sighting equipment.

3. If you are hit, try to avoid being destroyed.

Improve the ability of the vehicle's active and passive armor system, three-proof system and automatic flame suppression/explosion suppression system.

Fourth, if it is destroyed, try to avoid casualties.

Based on satellite positioning, real-time remote control and other technical means, the development of unmanned combat vehicles, the formation of leading unmanned vehicles in the front of the march or the installation of strong fire support unmanned vehicles when attacking urban fortifications.

Under the core idea of this design, there are all kinds of nonsense that someone has opened their minds, such as the plasma stealth that Mao Zi boasted after Maozi, and the optical stealth developed after the new century, countless ideas were written by Liang Yuan and deleted casually, and finally the plan of changing the shell was retained by Liang Yuan.

Since the replacement of the tank shell is based on the protection idea before the beginning, the design plan is relatively easy to come out.

First of all, the appearance of stealth is aimed at the gunship, you must know that the other name of the gunship is the tank killer or the treetop killer, due to the flight altitude and ground interference and other problems, the gunship of the enemy is mainly based on radar, infrared is used for attack guidance, such as the future of the longbow Apache boasted as a god by the bend county is a typical representative of the gunship.

Secondly, the appearance of stealth also has a good effect on the fight against early warning aircraft, the French Leclerc, the British Challenger, and the German Leopard have all done stealth repair tests to achieve ideal results, but the grass on the grave of the Soviet Union is old, and the number of German main battle tank equipment has dropped from 4,000 to 300, and Europe has no need to improve the army's armored forces, so that the test is only a test.

Relatively speaking, stealth is not a difficult point in this shell replacement plan.

Other similar modularization and improving maintainability are all design thinking problems rather than technical difficulty problems, and Zhu Yusheng has a general look.

Then Zhu Yusheng took a deep breath before turning the page, very formally with a little sense of ceremony, for the old man, the problem of reducing the infrared signal of the tank is also a problem in the world, although I don't know how Liang Yuan will deal with this problem, but judging from the messy handwriting that has been deleted and scribbled, this teenager's thinking is absolutely not exaggerated to describe it as talented and active, which makes Zhu Yusheng's sense of expectation for the following content higher and higher.

Liang Yuan's design description based on a momentary interest and brain hole is very thin, and the key indicators of shell replacement technology how to reduce the infrared signal of the vehicle are already the last page of this document.

After Zhu Yusheng turned the page, on the first line of the new page, he saw a few big characters that were larger than other fonts - thermoelectric effect.

In front of the big words thermoelectric effect, there are a few small words that are obviously added later—semiconductors.

Semiconductor thermoelectric effect?

Zhu Yusheng just pondered slightly, his eyes continued to look, and sure enough, he wrote in detail how to use a semiconductor thermoelectric effect based on the thermoelectric effect to reduce the infrared signal of the tank.

The thermoelectric effect, also known as the Seebeck effect, is a scientific term for a phenomenon in which electrons (holes) in a heated object accumulate an electric current or charge as they move from the high temperature region to the low temperature region with the temperature gradient.

The application of the thermoelectric effect began after World War II, and was first used in aerospace, military and other uses, such as the famous Voyager 1 spacecraft carried an isotope thermoelectric generator based on the thermoelectric effect, until the new century, Voyager 1 flew to the edge of the solar system far from the earth, and the thermoelectric generator is still working diligently.

During the Cold War, the thermoelectric generator was considered a top secret by the U.S. military and deployed to elite troops on the front line of the Cold War because of its ability to generate electricity using the flame obtained from raw wood.

After the end of the Cold War, semiconductor power sheets similar to assembling thermoelectric generators began to be used in civilian projects, such as thermodifference watches that used human heat as power generation at the turn of the century.

At present, the Cold War has not yet ended, and the semiconductor thermoelectric generator is not only a top military secret, but also a high-tech commodity embargoed by the Batumi Organization against the republic.

Of course, Zhu Yusheng knows that the temperature difference power generation is good, and he also knows that the application of this kind of technology abroad has reduced the infrared effect of tanks, but the problem is that the Republic has no talent to study this thing at all, and this thing was sky-high even abroad in the early nineties, and it is completely different from the 25RMB that has rotted the street in later generations.

Sighing, Zhu Yusheng's mood is a little complicated, in the end, it is unexpected and reasonable, with Liang Yuan's age and education, he can write this plan is already a genius in the absolute sense, although the plan is feasible in engineering, but the difficulty of obtaining technology, and the unbearable economic cost is a hard flaw that this plan cannot be changed.

Generally speaking, for every increase in the merit value of thermoelectric materials, it can be approximated that the thermal efficiency of semiconductor power generation sheets will increase by 3%-5%.

As far as Zhu Yusheng knows, since the fifties, scientists of all mankind have begun to look for semiconductor materials with higher thermoelectric coefficients and more suitable for temperature difference power generation, and as a result, forty years have passed, and the high-temperature superconducting materials that have become a research hotspot together with thermoelectric materials have made huge breakthroughs, and thermoelectric materials are only standing still as if time is frozen, and the best value of known thermoelectric materials to reach 1 seems to be the limit, and the efforts of countless scientists are as meaningless as a mirror.

Therefore, Liang Yuan's plan based on semiconductor temperature difference power generation materials has been secretly shot by Zhu Yusheng in his heart.

The problem is that Zhu Yusheng can't know that the so-called human breakthrough in the field of superconducting materials is written by someone, and after the new century of thermoelectric materials and superconducting materials, the processing technology of the two is actually partially similar, and what is more interesting is that the superconducting mechanism of the simple compound of magnesium diboride that someone cheated up is very similar to the nano-doping mechanism of the future breakthrough of the excellent value of 1 in thermoelectric materials, all of which change the electronic structure of Fermi energy and the vicinity。

Of course, due to the AXBX factor, Liang Yuan was temporarily delayed, and he couldn't AXBX finish processing and another apple smashed on his head, and Newton's apple tree was not specially planted for someone, so this new theory of magnesium diboride close relative Liang Yuan has been holding back in his heart.

But now because of AXBX, the year-long dispute between the Science and Technology Park and GE is coming to an end, Liang Yuan feels that it is time to get some goods at the bottom of the box to be used for the ballast of the Science and Technology Park, and the thermoelectric material is no better than magnesium diboride leaked in a throat, the technical difficulty of that thing is mainly in the processing mechanism, the merit value of the new process and the old process of the same material can be doubled, even if it is exported overseas, even if the testing materials alone think of the next century, they will not understand the reason.

And even if there is no Liang Yuan's prompt, GE in the United States will discover this thermoelectric material doping mechanism based on a new theory in 95, since time is running out, making a big deal is the right way.

Liang Yuan's shell replacement plan is based on new thermoelectric materials, and the two people will naturally come to different conclusions due to different assumptions under different basic conditions.
