Guo Dong and Qi Gongxun came again, Li He pretended to be surprised, "Two, long time no see." Pen, fun, and www.biquge.info

"I'm sorry, Mr. Li, I'm bothering you again", Guo Dong greeted Li He warmly, and hurriedly gave Li He a seat.

Li He's vanity was greatly satisfied, and he said with a smile, "No trouble, no trouble, who are the two of you this time?"

Guo Dong and Qi Gongxun glanced at each other, and then took out two documents from their briefcases.

Li He's eyelids jumped, and he made up his mind not to look at it, and he didn't look at it even if he was killed, otherwise he would have corns.

Guo Dong said with a smile, "We deeply admire Mr. Li's attainments in physics and mechanics, so today we are here to ask for advice." However, you also understand that some aspects of us are still not in a state of openness, and I hope that you will sign this confidentiality agreement before I show you this information. We also do the same."

Li He has not yet sacrificed his ego and fulfilled the spirit of his ego, if he signs it, it is equivalent to signing a deed of sale, and he cannot expect to leave the country in the next three or five years. In good conscience, he earnestly wants to contribute to national defense, but in terms of his own interests, he does not want to sacrifice himself.

Li He said, "Two, don't tease me, you two are editors, what can you keep secrets? I won't joke with you, I won't read any information, you two can ask any questions directly, I must know everything and say everything."

The two fell into silence for a while, this is an endless loop, before Li He signed a confidentiality agreement, it is impossible for them to disclose their identities, and if they do not disclose their identities, Li He will not be willing to sign a confidentiality agreement.

After they returned, in accordance with the technical plan provided by Li He, they developed a new Type 84 rocket launcher, which showed its might in the border conflict with Vietnam at the beginning of the year, and exploded a large area, which received an enthusiastic response in the army.

This time they actually came with a mission, they have been improving this rocket artillery, the latest experiment, the rocket fell upside down, the experiment failed, many people are very frustrated, hoping to get more information from Li He's mouth to solve the current dilemma.

Guo Dong finally said, "I can't hide it, we have sent your information and papers to the relevant research units, and the current trial research and development work has made great progress." We're still doing some more work on improvements, and we hope to get your cooperation."

Then, without violating the policy, he wrote some data and handed it to Li He.

Li He asked carefully several times before he affirmed, "It is caused by the long-term high-temperature ablation of gunpowder and the reduction of the strength of the steel pipe, which cannot withstand the pressure in the engine."

Qi Gongxun said, "Yes, we also infer this. At present, we have found a solution: that is, thickening the thickness of the engine shell and adding an insulation layer to the inner wall of the shell to prevent the temperature of the inner shell from being too high. However, what kind of material is used as the insulation layer, and what process is used to coat the inside of the engine shell? There is no precedent in China."

To say or not to say, Li He's heart was hesitant for a while, because of this technology, he and his colleagues had repeatedly tested for half a year, basically trying to use silicon carbide and magnesium oxide as solid ingredients and epoxy resin as binders.

This is just the most ordinary, the best arrow shell should be strong, heat-resistant and light, and the suitable material is C-C composite material.

How can this thing be produced?

Let's put it this way, 10 million equipment, running for a month, can probably make three 300-mm solid rocket engines.

In this way, you will find that these large-caliber rocket artillery can no longer be treated as "artillery", and their price no longer allows for a stormy style like early rocket artillery.

Of course, according to the domestic financial strength, scientific research level, it is not realistic to use C-C composite materials at all, this thing has to be bought with foreign exchange, and tens of thousands of dollars will be gone.

Li He thought about it for a while, let's dedicate it to the country, I really can't bear to let these old colleagues turn gray hair in a hurry.

Guo Dongdao, "Everyone knows about C-C composite materials, but this is really too expensive, and there is still no money." Let's paint it in the same way as you said."

Qi Gongxun said, "There is another problem of filling, which needs to be instructed."

Li He didn't hide his secrets, and said directly, "I remember reading a British journal last year, and the American M270 uses modular filling technology ......"

Conventional rocket artillery is extremely cumbersome to reload after launch, and even with an automatic loading vehicle, it takes a considerable amount of time to complete a reload and fire again. Therefore, starting with the American M270 rocket launcher, the new rocket artillery began to adopt modular launch/packaging barrel technology, and the rocket was placed in the packaging barrel when it popped out of the factory, and the packaging barrel itself was the directional tube of the rocket. Multiple directional tubes are then assembled into container-like containers. In this way, just load the container with the emitter and complete a reload.

After Li He finished speaking, the two of them were full of admiration, many technologies are not new or unheard of, many have been published and applied in practice, they can only sigh Li He's erudition and strong knowledge, domestic experts, foreign journals are like a treasure. The two of them secretly decided to go back and read the periodicals and newspapers.

When the conversation was almost over, Li He suddenly joked, "Since you are a military journal, you know that the richest people in the world are arms dealers.

Many large factories in China that can produce hundreds of tanks and tens of thousands of guns a month are living by producing simple household products such as gas canisters and pressure cookers......

Li He really couldn't stand it anymore.

"Isn't there still a gap with the world? Besides, we don't have an export policy yet", Qi Gongxun was amused by Li He, how could the two of them not know the benefits of export, if they have money, what kind of research and development can't be done, and they replied seriously, "You are an excellent teacher, where can we deceive you."

"The Iran-Iraq war, the Palestinian-Israeli conflict, which side doesn't need weapons? We can't sell the high-end ones, aren't there still low-end ones? If we can't fight for quality, let's fight for the price, and hug one to count one," Li He said more and more excited, "Besides, we didn't support African, Vietnamese, and Cambodian weapons before, and take the recent conflict between Thailand and Vietnam as an example, didn't we also support Thai weapons?"

What Li He said is in accordance with the historical trajectory, China's real arms exports also began around 85 years, and he even participated in the arms export orders of the Iran-Iraq war. He just wanted to bring this point forward.

When the Iran-Iraq war broke out, Saddam Hussein was simply the reborn parent of China's military industrial enterprises, ordering 2,000 tanks, hundreds of thousands of rifles, uncountable bullets and other weapons from China in one go.

This huge order at that time fed the Chinese military-industrial complex.

To put it mildly, the rabbit was poor and crazy at that time, and my rabbit dared to sell anything.

Paying money with one hand and delivering goods with the other, it is simply a childlike and conscientious arms dealer.

Whoever is a big tyrant in the Middle East doesn't need weapons, that is a powder keg, and at the same time a big treasury.

Most of the Chinese weapons commercials were filmed in the Middle East.

The Middle East region does not only have a large list of conventional weapons in the Iran-Iraq battlefield. Around '86, Israel the Saudis.

Saudi Arabia: Is Vostok 3 in stock?

Rabbit (manual smile): Yes, yes, yes, this time it costs tens of thousands of dollars?

Saudi Arabia (domineering face): Grass, tens of thousands of dollars, enough for a few shots, 3.5 billion dollars for Lao Tzu.

Rabbit: Guest officer, wait a minute, Oriental Express will send it to you immediately.

Israel: Nima, rabbit, what about friendship, the boat of friendship will capsize. This covers my whole territory, play a girl.

To this day, only rabbits dare to sell strategic missiles!

I'm afraid of being a hooligan.

Guo Dong was a little moved by what Li He said, he understood Li He's thoughts, since it was okay to give it away for free, why couldn't he export it?

That's a real value of foreign exchange!
