crazy! This tram has a range of 100,000 kilometers!

Chapter 73: Anti-Gravity Engine! The key to the space age!

Jiang Fan said in a deep voice: “System, I want to deduce military exoskeleton technology!” ”

【Ding! Host deduction military exoskeleton technology! Deduction success! Get the 2089 Dragon Military Exoskeleton! 】

[Wyvern-type military exoskeleton: The final upgraded version of the Red Dragon exoskeleton series. It mainly upgrades the two key technologies of the space survival cockpit and the anti-gravity propulsion engine, has excellent air-space flight capabilities, can perform combat missions in space, and is the core individual equipment of the future space force of the Dragon Country. 】

Space flight! Anti-gravity engine!

Jiang Fan’s eyes suddenly lit up, and he immediately began to study. Anti-gravity is more important to him than military exoskeletons. He immediately entered the state of research.

Soon, it was exciting.

“Against gravity! It’s really anti-gravity! ”

“With this technology, we can truly open the door to the space age and no longer be bound to the earth!”

When it comes to spaceflight, we have to mention a basic theory that can be learned in middle school: conservation of momentum.

So far, humans have only mastered one way to propel forward in a vacuum: the propulsion system ejects the spaceborne mass [the high temperature and high pressure gas produced by fuel combustion] outside the spacecraft to gain speed. There is only energy, which cannot be flown in space.

Therefore, the spacecraft must eject mass all the time, and these mass that is destined to be ejected wastes a lot of energy. This leads to a key metric: payload ratio.

The so-called payload ratio is the ratio of the payload to the overall mass of the rocket. Payloads are instruments, equipment, personnel, etc. that humans want to launch. In order to launch the payload into space, a lot of fuel is consumed.

For example, the largest Saturn 5 rocket in human history.

The rocket itself weighs 3000 tons, of which the fuel is 2000 tons.

Saturn 5 could send 118 tons of payload to low-Earth orbit, or 46 tons to the moon. In other words, the payload ratio sent to low-Earth orbit is less than 4%, and the payload ratio to the moon is only 1.5%. Therefore, launching rockets to explore space has always been an extremely wasteful luxury of resources.

But the anti-gravity propulsion engine is completely different!

The technical core of the anti-gravity propulsion engine is a theory called [gravitational field shielding].

[Gravitational field shielding]: A gravitational field shielding body can be constructed by technical means, shielding any direction and any size of universal gravity!

Jiang Fan quickly understood that this theory was a god-like existence! Any object with mass is always subject to gravity and will also generate gravity. The most obvious thing that humans feel is the gravity from the earth, that is, gravity.

At the same time, human beings are also affected by the gravity of the moon, sun, and Mars, but due to the principle of distance, compared with the gravity of the earth, it is very small and imperceptible to humans.

Gravitational shielding technology can create an arbitrarily shaped, invisible, directional gravitational field shield.

By adjusting the parameters of the [Gravitational Field Shielding Body], you can control it to shield the gravitational force in the specified direction, while retaining the gravitational force in other directions.

Even, shielding the gravitational force in a certain direction can not be 100% shielded, and the parameters can also be adjusted to shield a certain percentage and retain part of the gravity.

The anti-gravity engine is implemented using this theory.

Through the computer real-time calculation and adjustment parameters, adjust the earth’s gravity to keep it in balance with the gravity of celestial bodies from all directions in the universe, you can be suspended in the air, or fly in any direction!

“This thing can not only be applied to exoskeletons!”

“Civilian is also useful!”

“Like flying vehicles.”

“And more exaggerated, for example, flying cities?”

“Even build a heavenly palace and colonize the moon on a large scale!”

Jiang Fan’s thinking spread infinitely.

……

Because it is a military research institution, the lunch time of the red base is the same as that of the military, starting at 11:20, ending on 12, and not waiting for 11:30 when it expires, and the canteen is already lively.

More than 1,000 people ate in the large canteen, making a clanging sound.

Of course, after all, the research base is a place where high-tech talents gather, and the management is not too strict, and it is not as serious as eating in the barracks. Everyone sat in groups of three or five, chatting about topics of interest.

“Did you hear that? Today, Jiang Fan, the boss of the Shenzhen Dajiang Regiment, came to us! ”

A research dog mysteriously deliberately attracts the attention of another female research dog.

The other party was obviously also very gossipy, and said disdainfully: “Who still doesn’t know Academician Jiang, this is not a secret.” ”

“Hehe, do you know which direction he wants to study?”

The female research dog was surprised: “You also know this?” The progress board hasn’t been logged out yet, has it? ”

In the research center, everyone’s research direction has nothing to keep secret, and their progress will be listed on a special progress board for everyone’s reference.

Anyway, you can’t see any useful information just by looking at the progress. The scientific research dog said triumphantly: “Stimulating the space life support system, the leader of our research group is collecting information for Academician Jiang. ”

The female research dog frowned: “Want Academician Jiang to let the red dragon be used in space?” With limited fuel for individual soldiers, how far can a red dragon fly? Space is so vast, this research direction seems to be of little value. ”

Don’t look at them as just the most basic scientific research dogs here, but if they are released, they can also be called experts in related fields. She easily addressed the root cause of the Red Dragon’s suitability for the space environment: the payload-to-payload ratio problem.

“You’re so right! This is a problem that cannot be solved. ”

The scientific dog licked it without any psychological burden. In just over a day, Jiang Fan’s office has changed greatly.

There were hand-drawn draft drawings everywhere, and he picked up a random one and took a look at it to see that the law seemed to have greatly modified the overall design of the red dragon.

Ma Jun frowned slightly, and began to worry that the other party was too lofty and far-reaching. He admitted that the other party was indeed a genius.

However, the Red Dragon is the result of more than 20 years of hard work by everyone in the entire base.

If the other party grasps a certain subdivision for research, such as energy systems, such as control systems, he can accept the stand. But the overall revision is a bit frizzy.

To put it mildly, who is looking down on this.

Ma Jun is a very stable middle-aged and elderly man, of course, he will not say such things, and asked kindly: “Academician Jiang, I heard that you are collecting information on the space life support system, do you want the red dragon to use it in space?” If so, how are you going to solve the problem of payload ratio? ”

Jiang Fan looked at the information intently, raised his head and realized that it was Ma Jun, so he stood up with a smile and said hello. Then, he smiled mysteriously: “What if you don’t use fuel to propulsion?” ”
