Genius One Second Remember If You Want To Go? Let's provide you with exciting novels to read.
Guo Dong and Qi Gongxun were here again. Li He pretended to be surprised, "Long time no see, you two."
"Sorry to trouble you again, Teacher Li." Guo Dong warmly welcomed Li He and quickly gave up his seat to Li He.
Li He's vanity was greatly satisfied. He smiled and said, "It's no trouble at all. What are you two doing this time?"
Guo Dong and Qi Gongxun looked at each other and took out two documents from their briefcases.
Li He's eyelids twitched. He decided not to look at it even if he was beaten to death, or else he would grow a corn.
Guo Dong laughed and said, "Teacher Li, we deeply admire your achievements in physics and mechanics, so we're here today to ask you some questions. However, you must understand that we can't reveal certain things to the public. Before I show you this document, I hope you can sign this confidentiality agreement. We're just following the rules. "
Li He didn't have the spirit of sacrificing himself for the greater good. If he signed it, it would be like signing a contract to sell himself, and he wouldn't be able to leave the country for the next three to five years. From his conscience, he really wanted to contribute to the national defense, but from his own interests, he didn't want to sacrifice himself.
Li He said, "Can you two stop teasing me? You're just editors, what secrets can you keep? I'm not joking with you anymore. I won't look at any documents. If you have any questions, you can ask me directly. I'll tell you everything I know. "
The two of them fell into silence. This was an endless loop. Before Li He signed the confidentiality agreement, they couldn't reveal their identities. If they didn't reveal their identities, Li He wouldn't be willing to sign the confidentiality agreement.
After they returned, they developed a new type 84 rocket launcher according to the technical plan provided by Li He. At the beginning of the year, during the border conflict with Vietnam, it showed its prowess and blew up a large area. The military responded enthusiastically.
This time, they had actually come with a mission. They had been improving this rocket launcher. In the latest experiment, the rocket had fallen upside down. The experiment had failed, and many people were very discouraged. They hoped to get more information from Li He to solve their current predicament.
In the end, Guo Dong still said, "To be honest, we've already sent your information and thesis to the relevant research units. Currently, the research and development work has already achieved great progress. We're still working on some improvements, and we hope to receive your cooperation. "
Then, without violating the policy, he wrote down some data and gave it to Li He.
Li He asked a few times in detail before he said with certainty, "It's because the gunpowder in the engine has been eroded at high temperatures for a long time, and the strength of the steel pipe has been quenched, causing it to be unable to withstand the pressure in the engine."
Qi Gongxun said, "Yes, that's our deduction as well. At present, we have found a solution. That is to increase the thickness of the engine shell and to add an insulating layer to the inner wall of the shell to prevent the inner shell temperature from getting too high. But what kind of material would be used as the insulation layer, and what kind of process would be used to coat the inside of the engine casing? There is no precedent in the country. "
Should he say it or not? Li He hesitated for a while in his heart. Because of this technology, he had experimented with it repeatedly with his colleagues for half a year. Basically, he had experimented with silicon carbide and magnesium oxide as the solid components, and epoxy resin as the adhesive.
This was only the most common one. The best arrow shell had to be strong, heat-resistant, and light. The most suitable material was the C-C composite material.
What was the production capacity of this thing?
Let's put it this way. Ten million yuan of equipment, operating for a month, could roughly make three 300mm solid rocket engines.
In this way, one would realize that these large caliber rocket launchers could no longer be treated as "cannons". Their price no longer allowed for the storm-like firing style of the early rocket launchers.
Of course, according to the country's financial strength and scientific research level, using C-C composite material was simply unrealistic. This thing had to be bought with foreign exchange, and once it was fired, tens of thousands of US dollars would be gone.
Li He pondered for a moment. It was better to contribute to the country. He really couldn't bear to see his old colleagues' hair turn white.
Guo Dong said, "Everyone knows about C-C composite material, but it's really too expensive. We still don't have the money. Let's use the ordinary method you mentioned for now. "
Qi Gongxun said, "There's also the problem of loading. I need some guidance on this."
Li He didn't hide anything and directly said, "I remember reading a British journal last year. The American M270 used modular loading technology."
The traditional rocket launcher's loading work after firing was extremely cumbersome. Even with an automatic loading truck, it would still take a long time to complete a loading and fire again. Therefore, starting with the American M270 rocket launcher, new rocket launchers began to use modular launch/packaging bucket technology. The rocket was placed in the packaging bucket when it left the factory, and the packaging bucket itself was the rocket's directional tube. Then, multiple directional tubes were gathered together and loaded into a container similar to a container. This way, as long as the container was installed with the launcher, it could complete a loading.
When Li He finished speaking, the two of them were filled with admiration. Many of the technologies were not new or unheard of. Many of them had already been published and applied in practice. They could only sigh at Li He's encyclopedic knowledge. He was familiar with domestic experts and foreign journals. The two of them secretly made up their minds to go back and read the journals and newspapers.
When the conversation was almost over, Li He suddenly teased, "Since you guys are in the military journal business, you should know that the richest people in the world are arms dealers. Isn't it hilarious for arms dealers to say that they are short of money? I don't read much, don't lie to me. "
There were many large factories in the country that could produce hundreds of tanks and tens of thousands of guns per month, but they relied on the production of simple daily necessities such as gas tanks and pressure cookers to survive.
Li He really couldn't stand it anymore.
"Isn't there still a gap with the international standards? 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 exporting? With money, they could do any research and development. He even replied seriously," How can we lie to an outstanding teacher like you?
"The Iran-Iraq war, the Palestinian-Israeli conflict, which side doesn't need weapons? We can't sell the high-end ones, but don't we have the low-end ones? If we can't compete with quality, we can compete with price. One is one. "The more Li He said, the more excited he became." Besides, we have provided weapons to Africa, Vietnam, and Cambodia in the past. Take the recent conflict between Thailand and Vietnam for example. Didn't we also provide weapons to Thailand? "
What Li He said was based on the historical track. China's real arms export started around 1985. He even participated in the arms export order for the Iran-Iraq war. He just wanted to bring forward this point of time.
When the Iran-Iraq war broke out, Saddam was like the parent of China's military industry. He ordered 2000 tanks, hundreds of thousands of rifles, countless bullets and other weapons from China in one go.
This huge order supported China's military industry at that time.
To put it bluntly, I was so poor that I dared to sell anything.
One handed over the money, the other handed over the goods. It was a fair trade, a conscientious arms dealer.
In the Middle East, there was not only a big order for conventional weapons in the Iran-Iraq war. Which local tycoon in the East didn't need weapons? That corner was a gunpowder barrel and also a big treasury.
Around 1986, Israel angered Saudi Arabia.
Saudi Arabia: Do you have the Orient 3?
Rabbit (smiling): Yes, yes, yes. This time it's tens of thousands of USD?
Saudi Arabia (domineering face): Fuck, tens of thousands of USD? How many rounds can we shoot? Give me three and a half billion dollars.
Rabbit: Customer, please wait a moment. The Orient Express will send it to you immediately.
Israel: Damn, Rabbit, what happened to friendship? The boat of friendship capsized just like that. This covers my entire territory. What's there to play with?
Today, only China dares to sell strategic missiles!
I, Rabbit, am afraid of myself when I act like a hooligan.
Guo Dong was a little tempted by Li He's words. He understood Li He's thoughts. Since he could give it away for free, why couldn't he say it?
That's the real value of the goods in foreign exchange!
