Have you seen the sight of the rocket taking off?

It's a sharp arrow, plus a few fiery vents at the bottom. Flying in mid-air, it can also be disintegrated in stages and further propulsion in deep space.

This thing looks simple in structure, but the structure inside is fatally complex.

In addition to the integration of a large number of high-precision electronic instruments inside the rocket body, the propulsion system at the bottom of the rocket alone is a complex device for countless scientists.

As for the propulsion system, which is exposed and a bit like a funnel, the technical term in the aviation field is actually called a rocket engine.

This rocket engine sounds like a car engine with the word "engine", but in fact, the working principle is very different.

Like the [X-type engine] developed by Chen Hao before, it is a kind of internal combustion engine, and its working principle is the same as boiling water and boiling the steam to open the lid of the pot, which converts internal heat energy into mechanical energy, which is a relatively simple energy conversion.

But rocket engines are different!

This thing works on the impulse principle, has its own propellant, does not rely on outside air, and can work in space outside the dense atmosphere. The propellant is the kinetic energy converted into the working medium in the rocket engine, forming a high-speed jet discharge to generate thrust.

As for the thrust generated by the rocket engine, it is also big and scary!

For example, the well-known Long March 5 carrier rocket is a high-pressure refueling liquid oxygen kerosene rocket engine called YF-100, with a maximum thrust of 120 tons.

However, the predecessor of this engine is the RD-120 engine obtained from the former Russian Union in the 90s of the last century, after the project was established in 2000, after more than ten years of overcoming and magic reform, it was accepted and completed by the National Defense Science, Technology and Industry Bureau in 2012.

How else can we say that Western countries have imposed a strict technological blockade on China?

A country like the United States, which has experience in landing on the moon, successfully launched the Saturn 5 launch vehicle with a thrust of 3,408 tons as early as the 60s of the last century.

As for the five F-1 rocket engines on the Saturn 5 launch vehicle, the thrust of a single one can also reach the level of 680 tons.

Eldest brother!

It's a product of the 60s!

Although this F-1 rocket engine is not the largest thrust on the earth, when compared with the 120-ton gadgets currently used in Huaguo, you can imagine how terrifying the gap is.

After all, space equipment such as rockets and space shuttles are the most complex means of transportation known to mankind. Even in the 21st century, which is known as the information age, there are only a few countries in the world that have the ability to independently launch launch launch vehicles.

As for the rocket engine information that Chen Hao asked for from the big man in charge of the Huaguo engine field, it was not the well-known high-thrust fuel rocket engine.

Rather, it is an ion-electric propulsion system codenamed LIPS-200, which is commonly known as an electric rocket engine.

As for why the liquid rocket engine is not mature, but it is eyeing this ionic rocket engine with very little thrust, it is also out of confidence in [electromagnetic levitation technology].

You want to!

With the [electromagnetic levitation module] as the technical premise, the flight weight that restricts the development of the aerospace field has become a thin piece of paper, which can be pierced with just a slight poke.

After all, people blindly develop high-thrust rockets, and it is not because of the limitations of the earth's gravity!

According to the calculations of scientists, according to the existing space technology of mankind, if you want to send 1 gram of object into space, you must pay 62 grams of energy fuel.

The energy consumption ratio is 1 to 62!

But with [battery suspension technology], the most troublesome weight limit can be solved.

If an object that originally weighed 1 gram suddenly drops to 0, the energy consumption ratio of sending it into space will change from 1 to 62 to 0 to 62.

Anyone who has studied elementary school math knows that the number 0 has a special meaning, whether it is multiplication, division or 0!

Doesn't a 0 to 62 energy consumption mean an infinitely close to 0 energy consumption?

When the time comes, let alone a rocket, as long as Chen Hao is willing, the power of hooking his little finger can send Mount Everest into outer space!

However, theory is theory, and the actual operation is still a bit tortuous.

In addition to installing [electromagnetic levitation module] for the self-developed aircraft, Chen Hao also has to carry a large-capacity [graphene battery] into the aircraft as an energy reserve.

As for the LIPS-200 electric rocket engine, it became the power propulsion device of the aircraft.

Originally, the LIPS-200 electric rocket engine was a millimeter-class engine installed on the satellite to fine-tune the satellite's flight attitude.

The whole power system is measured down, but it is only 200 mm in size.

Eldest brother!

What is the concept of 200mm?

It's the size of a ruler for elementary school students!

How much thrust can be generated with such a small power plant?

It's a few kilograms!

However, in the vacuum environment of outer space, these few kilograms of thrust are enough to push an aircraft that becomes 0 grams under the action of the [Electromagnetic Levitation Module] to an unimaginable speed.

……

After solving the most complex power system of the spacecraft, Chen Hao began to search for the appearance of the spacecraft on the Internet.

After all, building a space vehicle is still a bit different from building a car.

In addition to considering the power output of the aircraft, it is also necessary to consider the violent air friction generated when the aircraft breaks into and out of the atmosphere.

This is the same reason as when a meteorite falls, once the aerodynamic design of the aircraft shell is not good, it is estimated that it will face the danger of disintegration before it flies out of the earth's atmosphere.

At that time, not to mention Zhang Sanfeng, who is a master of Taoism, even Chen Hao himself will face the danger of suddenly falling from tens of thousands of meters of outer space.

When it comes to this kind of crisis situation, in addition to the 50,000 gold coins and a bottle of [Invincible Potion] that can save Chen Hao's life, it is estimated that only the Buddha, God, and Jesus will come.

Therefore, when choosing the appearance of the aircraft, Chen Hao tried his best to choose those mature and extremely aerodynamic exterior designs.

"Cigar-shaped flying machines?"

"Isn't this just a lying rocket?"

"No, no, no!"

"How can you stuff 10 people into it when the time comes?" Chen Hao muttered to himself while browsing Baidu pictures.

After flipping through dozens of pages of search photos about "aircraft", Chen Hao found that most of the netizens' thinking was limited to mature designs such as space shuttles, rockets, and airships.

It's a really good design, and the aerodynamics are perfect.

But you want to!

Chen Hao went into outer space this time, but it was a private action without approval and reporting.

To put it mildly, it's Heifei!

Once in outer space, let alone a ground observation station, it is estimated that countless spy satellites floating in low-earth orbit will be able to take pictures of his privately built aircraft inside and out.

After all, this aerospace field has always been controlled by a few countries in the world.

You suddenly have a huge thrust that does not require a fuel rocket engine to suddenly rise into outer space, and once it is discovered, it will not cause a major earthquake in the human scientific and technological circle?

So after flipping through dozens of pages of Baidu photos, Chen Hao planned to change the keyword and search again.

However, just as he was about to reopen a new web page, an oval-shaped flying machine in the photo gallery suddenly broke into his sight.

As for the corner of this photo of the oval flying machine, the watermark of "UFO Home Network" is very clearly displayed.

"it!"

"UFO House Forum?"

"That's right!"

"Why didn't I think of that?"

"Lao Tzu can build a UFO!"
