Technology Bigshot Chapter 605: : Curvature engine? ]

……

The eloquent Xiao Xuanyu slid the information display panel of the nuclear fusion rocket to the side of the "trash box", and turned to look at Ren Hong, who was listening carefully, saying: "The British have been researching since the 1970s. The engine promotes technology, and nuclear fusion rockets are one of the main research projects of the Daedalus Project. The key point of the technology is controllable nuclear fusion. If the British realize this key technology, nuclear fusion rockets are very promising."

Speaking, I want to see the next one, said:

"This is an idea proposed by the Germans, called 'Barcelona ramjet'." With a wave of his right hand, Xiao Xuanyu adjusted a spotlight to the best viewing angle of the two, he added: "'Barcelona The German ramjet 'shows the Germans' style of steady technological expansion step by step, but it is also self-defeating because of this."

"Almost all rockets and new engine technologies, including those mentioned above, face the same fundamental problem, that is: if you want more acceleration, you need to carry more fuel, so here comes the problem, carry more fuel It means that the mass of the aircraft increases, which in turn reduces the acceleration, almost in an endless loop."

"'Bassard ramjet engine'?" Ren Hong was stunned for a moment, and some related information immediately appeared in his mind. When he thought of this, he shook his head and said with a smile: "No wonder the Germans just imagined , the so-called 'Barsad ramjet engine' is just a joke, this engine technology is too unreliable, it completely deviates from the original design purpose, I can make a bold judgment, this thing will only exist in the imagination, dare to It's either a lot of money or an idiot."

"Indeed!" Xiao Xuanyu said with a smile, tapping on the spotlight screen with his left hand and flicking it to the side, which is equivalent to cracking the engine technology.

In the eyes of the two, the Germans are indeed funny. The "Barsad ramjet" proposed an unreliable solution to solve the problem of the infinite loop.

According to the Germans' vision, the "Bassard ramjet engine" is also a nuclear fusion rocket, but the way to obtain propulsion does not rely on nuclear fuel, but hydrogen ions in space. They envisage using a huge electromagnetic field. Inhale hydrogen ions from the universe into the engine.

But how many hydrogen ions can there be in an almost vacuum of space? If such a vision is really to be realized, then the range of the electromagnetic field must reach thousands of kilometers, which is almost impossible. In order to solve this problem, the Germans proposed a very funny way through artificial means, which is to launch fuel from the earth in advance on the calculated channel, and then allow the spacecraft to obtain fuel along the way without the need for a huge electromagnetic field. .

It is estimated that even the original proposer would find this idea unreliable, let alone others. No wonder Ren Hong shook his head repeatedly when he heard the 'Barsad ramjet engine' and eliminated it without hesitation.

Xiao Xuanyu paused, then said: "The following is the light sail engine technology, we have already achieved it, but the shortcomings are also obvious, whether it is the light sail front engine propulsion technology or the technologies listed above, there is a The same point is limited to short-distance travel, which is inefficient. For our light sail forward propulsion engine technology, the longest voyage time between Mars and the earth is 100 days. According to the traditional propulsion method, the speed is already very fast. "

"But such speed and efficiency are still not the usual hallmarks of k2-class speeds, so what's further? What about Jupiter, Saturn, and even the Kuiper Belt at the edge of the galaxy? How much time is wasted sailing back and forth? On? And there is a fatal weakness after the light sail is deployed. The front engine makes Mars Express unable to pass through the asteroid belt at all, which means that it can only operate in the asteroid belt."

"Well, I listen, you continue to speak." Ren Hongdao.

Xiao Xuanyu nodded and continued: "The above engine technology can basically be ignored. I have two other solutions here, such as 'hyperspace engine'. If the universe has more dimensions, does that mean that it can be used? What about the 'hyperdrive' spacecraft traveling through multi-dimensional space at extreme speeds?"

Ren Hong shrugged and said, "Hyperspace engine? Under the system of modern physics laws, this is almost incomprehensible."

"Indeed, then there are wormholes! But this is a point to be considered in k3-level civilization technology, not in the scope of k2-level standard speed." Xiao Xuanyu said, and then called up the last display panel, saying: "The front It can be ignored, but perhaps we should pay attention to the technical vision of the El Kubir engine!"

"Curvature engine?" Ren Hong looked curiously and had an idea in his heart, but he didn't say it yet. He wanted to hear the other party's opinion first, and said, "What do you think about the curvature engine?"

The "El Kubir engine" is the so-called "curvature engine", also known as the "warp engine".

This technical idea is famous in the world, thanks to the warp drive that appeared in the "Enterprise" in the movie "Star Trek", it can be said to be famous.

Xiao Xuanyu saw Ren Hong say this, thought for a moment and then said: "The Erkubir engine, or the warp flight, uses loopholes in the laws of physics to break the limit that the speed of light cannot be surpassed to achieve super-light speed."

“However, there are many unavoidable problems with the El Kubir engine. The first one is that the engine needs the so-called 'exotic matter', which has negative mass and great negative pressure. What is 'strange matter'?" Xiao Xuanyu shrugged and asked himself, "Antimatter?"

added: "I don't know anything other than the so-called indispensable 'exotic matter', one of which is the theory that the energy required to maintain the 'warp bubble' is theoretically greater than the total energy of the universe. High-speed sailing will also produce a large number of radiation sources, threatening the safety of the crew. Is there a more important so-called 'exotic matter'? Without this thing, there is no need to talk about warp sailing, and no signal can be sent in the warp sailing state. That means the crew can't control the ship in warp speed, and I don't think even experienced crew members would want to fly such a ship."

Xiao Xuanyu said helplessly: "The El Kubir engine technology is the ideal k2 speed, but it is almost impossible to achieve."

"Also." Ren Hong stared at the "Star Trek" protagonist Enterprise displayed on the spotlight screen and said: "The other point is practicality, the energy required to travel at warp speed is even the entire human society. The sum of the current output energy cannot be achieved, which determines that warp speed travel is too extravagant. In addition, if the spacecraft loaded with the Erkubil engine will be in an embarrassing situation, faster than the speed of light, how many times the speed of light? Ten times? One Hundred times? Not to mention the energy consumption, how big is the universe? Even 100 times the speed of light across the Milky Way will take 1,000 years, let alone sailing across galaxies.”
