The toy factory is transforming, are you transforming into a military factory?

Chapter 117 Kuafu Engine!

From the moment the rocket breaks through the atmosphere, once the aircraft escapes the gravity of the earth, the propulsion system will face three important problems.

"The first one is thrust, which determines how fast the engine can accelerate the spacecraft."

"The second is mass efficiency, how much thrust the engine can produce for given fuel materials."

"The last one is energy density, how much energy can be produced from a given mass of fuel."

Considering these problems, Chen Yuan needs to make a lot of changes in conventional engines.

You must know that the current chemical propulsion system can provide a lot of thrust, but the mass efficiency of chemical rockets is not particularly high.

The energy density of rocket fuel is also not high.

The Saturn 5 launch vehicle that sent astronauts to the moon generated 3500 million Newtons of force during liftoff and carried 36 liters of fuel.

Although most of the fuel is used to get the rocket into orbit, the limitations are obvious.

Going anywhere requires a lot of heavy fuel.

"As for the disadvantages of electric propulsion, it is also more obvious," Chen Yuan said. "The energy of the electric propulsion system comes from the sun. In theory, it is inexhaustible. But in fact, the farther the spacecraft is from the sun, the less effective the solar energy is. The tinier.”

Therefore, the nuclear electric thruster that Chen Yuan is currently researching is the most promising.

In order to develop nuclear electric thrusters further and faster, Chen Yuan led the nuclear energy team to begin a three-month retreat.

In the past three months, only Dafa Toy Factory has been operating as usual, but no news about Xingyao Aerospace has leaked out.

On the Internet, many people are even discussing and speculating whether the boss of Shining Star Aerospace has given up on the development and production of nuclear rockets.

"I think such a result can be guessed a long time ago. After all, in the 21st century, humans do not have enough ability to build nuclear rockets."

"Even if it fails, we should give you some assurance. I think Xingyao Aerospace is just trying to sway our appetite."

"Forget it, brothers, don't pay attention to nuclear rockets. Even if this thing is really successful, what does it have to do with us ordinary people?"

Some netizens feel that aerospace technology is too far away from them and they will not enjoy the benefits it brings, so they do not want to pay too much attention to it.

But other netizens do not agree with this statement.

"Now that rocket recovery technology has matured, this means that commercial rockets will become more popular. In the future, flying on a rocket may be as easy as flying on an airplane."

"What's wrong with ordinary people? When the country builds a rocket station, ordinary people like us can fly into space on rockets as long as we buy a ticket."

"As long as the nuclear energy rocket is successfully developed, a one-month trip to Mars will no longer be a dream!"

More and more netizens have begun to fantasize about space travel.

They are also looking forward to the news that Xingyao Aerospace can bring success.

The outside world is paying more and more attention, and even the entire country has begun to focus all its attention on Xingyao Aerospace.

Every day, besides going to work, the first thing people do is check online for news about Xingyao Aerospace.

Faced with such attention, Chen Yuan also knew that he had to show some results.

After half a year of research, Huangtian finally paid off, and netizens received the first long-awaited news from Xingyao Aerospace.

"This time, our goal is the sea of ​​stars!"

Xingyao Aerospace only posted such a simple post, but it attracted countless onlookers and crazy comments from netizens. "Any news on nuclear rockets?"

"Has your factory already made a breakthrough in nuclear rocket technology?"

"Say it quickly, I'm really worried."

"Can you please stop selling it? I'm really excited. In the past six months, there hasn't been a day when I haven't been paying attention to the news about nuclear rockets."

Netizens are almost all waiting for this moment, because this moment can make them feel extremely excited and happy.

However, the West is also paying attention to this moment,

But this moment made them worried.

NASA Space Admiral Lonkarski looked gloomy and stared at the latest reports on his mobile phone. His heart was no longer as calm as before.

After a long time, his anger was finally vented: "Damn it, what kind of achievements has Xingyao Aerospace achieved, and why are they letting it slip at this critical moment!"

What Lonkarski is most worried about is that China has really made a breakthrough in nuclear rockets.

That means that the Federation is at least thirty years behind China in the aerospace field.

The rocket recovery technology that the Federation was once proud of was also solved by China.

On this track, they have really fallen too far behind China.

So Lonkarski turned his attention to Musk who was standing aside: "How is the lunar exploration program going now?"

Musk is facing a formidable enemy, but fortunately, Space Exploration Technology Company has made rapid progress in this regard.

He said truthfully: "The relevant lunar exploration rockets are ready. We have entered the lunar landing deployment period. It will only take half a year to officially launch the rocket to the moon."

Hearing that the lunar exploration plan was progressing so smoothly, Lonkarski finally felt relieved.

Regardless of the development of China's aerospace industry, as long as the Federation can land on the moon ahead of schedule, the subsequent events will no longer be important.

At this time, many people on the Internet are still asking whether Shining Star Aerospace has made progress in nuclear energy rockets.

Many people are curious about what message Shiningyao officially released online.

While there was heated discussion among the outside world, Chen Yuan was not in a hurry to announce the news.

"The space engine is different from others, and the strategic significance it brings is huge. In order to avoid accidents in our moon mission project, I have not further announced the news about the nuclear rocket."

At this time, Chen Yuan was patiently explaining to Ying Ludong and the others why he had not replied to netizens a second time.

They were taken to a warehouse with a miniature rocket engine in the center.

It is said to be micro, but it is still the size of a small car, but it is much smaller than a conventional rocket engine.

When everyone saw this engine full of violent aesthetics and technological power, everyone couldn't help but marvel at its sophisticated structure.

Chen Yuan introduced from the side: "What you are seeing now is the 'Kuafu Space Engine'. The energy density it provides is unbelievable."

"The uranium fuel used produces an energy density 400 million times higher than the typical chemical rocket propellant 'hydrazine'."

"It's much easier to send small amounts of uranium fuel into space than to carry thousands of liters of chemical fuel."

"So when you see Wenyue again in the future, it will be slimmer than now and it will carry more weight."
