The two space-specific engines, the pulse-detonation engine and the plasma engine, not only have a rough structural drawing, but also have a variety of parameters and requirements.

From the performance point of view, it is obvious that each has its own uses, and there is a special red pen circle near some performance indicators, and the requirements and data of the proposed alloy materials should be met at least.

These data have very strict requirements for the accuracy of the processing process and the texture of the material, even more demanding than the old American F119-PW-100 vector propulsion engine, and even the F119-PW-100 vector propulsion engine cannot be mass-produced in China, let alone this more demanding space engine.

It's going to be mounted on a space shuttle.

Lin Mo quickly began to communicate with the left-wristed gold-based dragon in his mind, searching for a suitable formula.

Pulsed detonation engine (PDE, pulsedetonationengine) is a new concept engine based on detonation combustion, which is currently the only engine concept that can work in dual modes, which can work in both air-breathing and rocket-like modes.

The detonation wave generated by detonation combustion causes the pressure and temperature of the explosive fuel to increase rapidly (the pressure can be as high as 100 atmospheres, and the temperature can reach 2000 °C). Therefore, the detonation combustion engine can achieve the purpose of compressing the gas without the traditional compressor and turbine parts, so that the structure is greatly simplified and the cost is greatly reduced. In addition, since the detonation wave propagates extremely fast, reaching several kilometers per second, when the detonation frequency is high (up to 80~100Hz), continuous thrust can be generated.

If it is applied to the flight out of the gravitational circle, it has a very high cost performance and can climb to heights that even fighters cannot reach.

The US "Aurora" high-altitude and high-speed reconnaissance plane uses a pulse-detonation engine, which can reach an astonishing speed of Mach 7 and can fly unscrupulously in the airspace of any country and take pictures.

The plasma engine is likely to be a special engine for space navigation after the pulse detonation engine went into space, using the Lorentz force to accelerate charged atoms or ions through a magnetic field. to drive a spacecraft in reverse, and particle accelerators and railguns are all based on the same principle.

Unlike rocket engines, which consume thousands of tons of propellant in just a few minutes, plasma engines provide relatively little thrust for a certain amount of time, and then once in space. They will be like sailboats with a tailwind, gradually accelerating their flight, accumulating propulsion until they outpace the chemical rocket.

Like the full-power variable specific impulse magnetic plasma engine on the information in Lin Mo's hand, the time to land on Mars will be shortened from 250 days to 39 days, and it will be more than a month to Mars, and you can go to the solar system.

Do you really have to start building Starfleet? Lin Mo touched his chin. A huge amount of 500 billion yuan is smashed, which is almost 100 aircraft carriers, which is enough to turn the rice of Lao Mei solidly.

The investment cost of the International Space Station is almost more than 100 billion US dollars, and with the current level of technological progress, although the "Buzhoushan" space station is larger, the cost will not necessarily be higher.

"Ask him if there is an experimental prototype, and we can take the opportunity to analyze it."

Naturally, this information is like a glutton. aroused the greed of the golden dragon, full of warm thoughts and lust, after eating and drinking without worry. This dragon, who is comparable to a professional miner, has now simply degenerated into a tech nerd.

This thing is now fundamentally two unwavering supporters of everything.

Everything related to science and technology should be packed and taken home for good research.

Anything that has never been eaten must be bitten before you are willing to die.

"Do you have any test subjects?"

Lin Mo carefully read this information and looked up at Major General Sun.

As an equivalent exchange principle, it was impossible for Lin Mo to force this dragon to hand over the alloy formula, he still took the idea of the gold dragon as his own.

"Look at the test subject? This, this one is a little harder, wait! Let me ask you first. ”

Major General Sun is a little difficult, this level of secrecy is higher, and if you are not a relevant person, you can't touch this kind of thing. After all, there is a request for people, and it is impossible to detain Lin Mo here permanently to copy the alloy formula, in order to ensure that the alloy formula he got meets the requirements, he still got up and made a phone call to ask his superiors.

After a few moments, he returned to the couch and said, "Go." I'll show you. ”

If it weren't for Lin Mo's identity as an aviation expert, he wouldn't have agreed to Lin Mo's request.

Pilots are future astronauts, and aviation experts may also become future aerospace experts.

A person has cobbled together a fighter jet that at least seems to be the fourth generation, and what to say is already bewitching enough, God knows how far Lin Mo will grow in the future.

Follow Major General Sun to take the elevator straight to the bottom four floors of the administrative building, and there is a hole under this seemingly inconspicuous building, which seems to be an underground defense project that can resist the eighth level of nuclear power.

The slogan of the Cold War between the East and the West did not seem to be as many people understood, but it was only a temporary response to the party's call.

In fact, the real originator of this slogan in modern times is the Ministry of Astronautics.

The outbreak of the Zhenbao Island Incident on March 2, 1969 triggered a confrontation between China and the Soviet Union.

On August 28 of the same year, the Washington Star newspaper published a news item in a prominent position with the headline "The Soviet Union Wants to Carry Out a Surgical Nuclear Strike on China."

The article said: "According to reliable sources, the Soviet Union intends to use medium-range ballistic missiles, carrying nuclear warheads with a yield of several million tons, to carry out surgical nuclear strikes on China's important military bases -- the Jiuquan and Xichang missile launch bases, the Lop Nur nuclear test base, as well as Beijing, Changchun, Anshan and other important industrial cities." ”

Mao/Ze/Dong resolutely put forward the principle of "digging deep holes, accumulating grain extensively, and not seeking hegemony", and the whole country soon entered a situation of "preparing for war"; many enterprises turned to military production, the national economy began to turn to a state of imminent war, a large number of factories turned to mountainous areas and third lines with closed traffic, and implemented the configuration of "mountains, scatters, and holes", and Beijing and other big cities excavated underground fortifications.

As one of the important bases of the Ministry of Aerospace in Jiuquan, the No. 5 Training Center directly began the deep excavation project at the beginning of the planning.

Lin Mo followed Major General Sun through a long passage, maybe two kilometers long, maybe five kilometers long, wide and almost four tanks in parallel in the deep passage, the eyes were all the same cement gray, the walls were hung with communication fiber optic cables and power supply lines, and the top was hung with lights that would never go out.

I am afraid that maintaining this underground project will also require considerable investment, Lin silently followed behind Major General Sun, closed his mouth tightly, stared at the ground under his feet, and did not look around, to avoid unnecessary curiosity.

In such a place, even if a cat has 900 lives, it can still kill curiosity.

When passing through the security gate, Lin Mo saw soldiers with guns guarding each node, all manually and mechanically, and there was no possibility of being invaded by the network.

A large room, about 800 square meters, is extremely empty, not a single pillar can be seen, and the walls are embedded with honeycomb-shaped silencing sponges at intervals, so that the sound of walking and talking will not have a strange echo.

Although I don't know how deep it is, it is not the slightest bit dark and damp, but the temperature is very pleasant, and the ceiling is more than six meters high, which is composed of LED light panels, and the snow white and bright when you look up is dazzling, illuminating everything in the room.

"It's here!"

After Major General Sun brought Lin Mo into this empty room, he stopped.

When he came in, Lin Mo looked at the sign at the door, "9D".

Maybe there are many such rooms, although I don't know what they are used for, just looking at such a large size, there is no problem with using it for military storage, as a warehouse, or as a production workshop.

Such places are also common in the underground base of the "Dark Night" special service team, and usually this vacant place is called a standby area, which means waiting to be used anyway.

Seeing Lin Mo turn his head and look around, Major General Sun seemed to guess Lin Mo's thoughts, and said, "Don't worry, wait a while, they are sending them over, the level of secrecy here is very high, I don't have the authority to take you to the production workshop, I can only let them bring things out and let you take a look." ”

After a while, two battery cars dragging a wheeled platform slowly drove in from the door where Lin Mo and Major General Sun came in.

There were also several gun-wielding soldiers wearing digital individual tactical armor blocking the door, and Lin Mo glanced at it, it was very familiar.

The enhanced version of the "Dragon Guard" of Henghai Battle Defense was worn in North America, and it was half a year higher than the standard version worn by the combat squadron of the "Dark Night" special service group.

The Ministry of Aerospace couldn't get the Dragon General, because the only "Dragon General" experimental tactical armor was wearing Lin Mo at the moment.

Those soldiers were stunned when they saw Lin Mo wearing a "dragon general" tactical armor, this body had never been seen before, the "dragon guard" system automatically recognized the "dragon general", almost subconsciously thought that it was the commander of the underground base, and invariably saluted Lin Mo with a military salute.

This is due to the difference in the level of tactical armor, and the performance of the "Dragon General" is obviously more powerful.

"Hmmm! Well! Comrades have worked hard!"

Lin Mo shook his hand with a Patton-style military salute and smiled happily, Major General Sun couldn't help but smile on his face, this guy really regarded this place as his own territory.

Several technicians wearing special one-piece dust-free overalls jumped out of the car and parked the two wheeled platforms next to Lin Mo and Major General Sun.

"The V-11 pulse detonation engine and the Vasimr-5A5 magnetic plasma engine were delivered, and they were recovered in half an hour!"

A technician delivers a folder, even if it is picked up from the production floor, there is a time limit.

"Thank you!" Major General Sun signed for it, and after signing, he glanced at Lin Mo, "Take a look!"
