After listening to the introductions of Lin Xiaolun and Nevsky, Li Qingye looked at Dr. Martin Don Quixote, the technical leader of the last project.

Martin explained with some embarrassment: "Chairman, my side is not finished yet. ”

"It's a problem that metallic hydrogen can't be passivated, right?"

Martin nodded: "Yes, that's the problem, I used various schemes, but I couldn't make the metallic hydrogen slow down the explosion. ”

Obviously, Li Qingye had expected this problem for a long time.

After all, the semi-finished metal hydrogen manufactured by Homo sapiens is very unstable, and even if other auxiliary materials are added, as long as the temperature is higher than minus 175 degrees Celsius, it will become a big bomb.

However, the specific impulse and thrust of metallic hydrogen are very attractive.

As long as the burst speed of metallic hydrogen can be about the same as that of ordinary solid fuel, a launch vehicle using metallic hydrogen as fuel can easily send hundreds of tons of payload into outer space.

As for why not use the Longeland cannon, because the Longelang cannon can't send astronauts to outer space, and at the same time, the restrictions on various equipment are very large.

After all, during the launch of the Longeland cannon, tens of thousands of G of load will be generated, not to mention astronauts, even ordinary electronic components will be crushed under this pressure.

The biochips and biocomponents used by Homo sapiens in the shells of the giant cannon are all manufactured through a special process.

Its core technology is a nutrient-rich liquid, and under the wrapping of this liquid, biochips and cell-based components can resist the instantaneous load of tens of thousands of G.

This is also the reason why the cannonball's shells can still control the various parts inside it after they have been fired.

After all, liquids are incompressible, and biochips and cellular components are filled with liquids inside and out, which can resist this ultra-high load.

As for the engines inside the shells of the giant cannon, the missile version, there are only specially made solid-fuel rocket engines.

As a satellite version of the artillery warhead, the first stage is a solid-fuel rocket engine, and the second stage is a liquid oxygen-methane liquid engine.

Li Qingye touched the stubble on his chin: "Since it can't be blunted for the time being, what do you think?" ”

Dr. Martin thought for a moment: "Large launch vehicles fueled with metal hydrogen are one of the few paths we can take to catch up with the great powers in a short period of time, and if we can succeed, then we can quickly overtake in corners." ”

Of course, it is also possible to roll over in a corner.

"Do you want to continue working on this project?" Li Qingye had already understood.

And Martin was also nervous in his heart, after all, if Li Qingye did not agree to continue this project, the metal hydrogen launch vehicle project would definitely not be able to continue.

He hurriedly said: "Chairman, I will work hard to make the metal hydrogen launch vehicle practical as soon as possible." ”

Li Qingye waved his hand: "That's it!" Since passivation is not possible for the time being, then change the scheme and directly use the explosive propulsion scheme. ”

"Uh......" Dr. Martin looked confused.

Lin Xiaolun reminded in a low voice: "Chairman, isn't there a Longgrand cannon project in the explosion propulsion plan?" ”

"Where do you want to go?" Li Qingye raised his eyebrows slightly: "I mean using metallic hydrogen on launch vehicles." ”

"But metallic hydrogen cannot be passivated, and the launch vehicle cannot withstand the shock wave generated by its explosion." Dr. Martin scratched his hair with some embarrassment.

Li Qingye patted his forehead: "How do you learn from Amerika?" Won't we learn from our northern neighbor? ”

What? Everyone was confused.

Li Qingye reminded them angrily: "Since the materials can't be improved, why don't you try to get a breakthrough in the design scheme?" ”

The reason why he said that Martin and the others fell into a dead end in America's thinking.

It is because the navy of America ordered a number of Independence-class and Freedom-class littoral combat ships, and these ships are "good things" made of aluminum alloy, and in order to cope with the corrosion of seawater, each ship costs more than 70 million US dollars per year.

The solution of a large eastern country is to build an aluminum alloy boat of several hundred tons, and when the ship does not need to work, the ship is directly hoisted ashore, which solves the problem of the aluminum alloy of the hull being soaked and corroded by seawater.

The materials are not good, the engineering is to make up.

This is actually a train of thought.

After listening to Li Qingye's reminder, everyone finally reacted.

Lin Xiaolun was the first to react: "Indeed, if the design is improved, it is still possible for metallic hydrogen to be applied to launch vehicles." ”

And Nevsky came to his senses, he took out his tablet and projected a hologram:

"It can be designed like this, isn't Aoba Aviation developing an explosive shock engine? Work directly with that side and use the Burst Shock Engine.

The metallic hydrogen is then made into small fuel balls, and a launcher similar to a magazine is designed, which is surrounded by a liquid oxygen storage tank to cool the metallic hydrogen.

When in use, liquid oxygen and metallic hydrogen fuel balls are injected into the engine combustion chamber, so that a continuous supply of fuel can be achieved, allowing the launch vehicle to fly into outer space with uniform acceleration. ”

The embarrassed Dr. Martin looked at Nevsky with a little aggrieved expression: "You kid has said everything, what else do I say?" It's a shame......

But Nevsky did not see his expression, but continued to describe his plan.

After listening to it, Li Qingye was satisfied with Nevsky's plan, the only difficulty of this plan was the ultra-low temperature enclosure equipment for metal hydrogen fuel balls.

In this regard, Nevsky adopted the "take-it-or-leave-it" doctrine without any psychological burden, anyway, there was no patent problem in the field of aerospace, and he directly proposed to use the French cryogenic enclosure technology.

As for design problems such as fuel balls, storage clips, engines, etc., Nevsky believes Martin can solve them.

Although Martin's technical research and development ability is indeed quite mediocre, it is only poor in terms of creativity, and other abilities are still okay.

Now that the design ideas are all there, if Martin still can't do it, then it's better to just go home and sell sweet potatoes!

Li Qingye looked at Martin: "Dr. Martin, according to Dr. Nevsky's ideas, you can complete this design over there, right?" ”

"Uh...... Yes, rest assured, Chairman, I will be able to complete the design soon. Martin hastened to say that he could get the job done.

The problem of the last project was solved, and everyone finally felt a little easier.

The technology of the metal hydrogen launch vehicle has been solved with the research and development ideas, and there will be basically no major problems in the next research and development process.

And the significance of the metal hydrogen launch vehicle is absolutely extraordinary.

Everyone is imagining the future of aerospace, as long as the metallic hydrogen launch vehicle is successful, it means that Homo sapiens will achieve corner overtaking in the aerospace field.

Although there are some regrets that it is difficult to store and passivate metallic hydrogen, which is difficult to use in the military field.

But Li Qingye is already quite satisfied, technological progress is to go step by step after all, his existence has accelerated the technological development of Homo sapiens, and also made Homo sapiens' research in the basic field somewhat insufficient.

These days, during his expeditions around the world, he has discovered that Homo sapiens is not doing well in the field of basic science.

Li Qingye also felt helpless about this, research in the field of basic science requires a lot of talents and resources, but it is difficult to transform this research into applied technology.

He has already made up his mind to promote the development of Homo sapiens by setting up a department within Homo sapiens dedicated to investing in and managing basic scientific research.
