Chapter 600

……

Xiao Xuanyu slid the information display panel of the nuclear fusion rocket to one side of the "dustbin" and turned to Ren Hong, who listened attentively. He said: "the British have been studying the engine propulsion technology since the 1970s. The nuclear fusion rocket is one of the main research projects of the" daedalos project ". The key point of the technology is controllable nuclear fusion It's a very promising technology for fusion

Then he looked at the next one and said:

"this is the German idea, which is called" bashad ramjet engine. " With a wave of his right hand, Xiao Xuanyu adjusted a spotlight screen to their best point of view. He added: "the bashad ramjet shows the German style of steady technological development step by step, but it is precisely because of this that it is self defeating."

"Almost all rockets and new engine technologies, including those mentioned above, face the same fundamental problem: if you want to get more acceleration, you need to carry more fuel. Then the problem is that carrying more fuel means increasing the mass of the aircraft, which in turn reduces the acceleration and almost dead cycle."

"Basad ramjet?" When Ren Hong was stunned, some relevant information immediately appeared in his mind. At the thought of this, he immediately shook his head and said with a laugh: "no wonder the German just imagined that the so-called" bashad ramjet engine "is just funny. This engine technology is too unreliable and completely deviates from the original design purpose. I can make a bold judgment that this thing will never change It's far away from the assumption that the one who dares to invest money is either a lot of money or a fool. "

"Indeed Xiao Xuanyu said with a smile. With a flick of his left hand, he flicked the focus screen to one side, which was tantamount to cracking the engine technology.

In their eyes, the German is indeed very funny, "bashad ramjet" in order to solve the problem of dead cycle, put forward a way is not reliable.

According to the German imagination, "bashad ramjet" is also a kind of nuclear fusion rocket, but the way to get propulsion power is not relying on nuclear fuel, but hydrogen ions in space. They imagine using huge electromagnetic fields to suck hydrogen ions from the universe into the engine.

But how many hydrogen ions can there be in almost vacuum space? If we really want to realize this idea, then the electromagnetic field will reach thousands of kilometers, which is almost impossible. In order to solve this problem, the German put forward a very funny way to solve this problem, which is to launch fuel from the earth in advance on the calculated channel, and then the spacecraft can obtain fuel along the road without huge electromagnetic field.

It is estimated that even the original proposer himself would find this kind of assumption unreliable, let alone others. No wonder Ren Hong shook his head again and again when he heard of the "bashad ramjet engine" and did not hesitate to eliminate it.

Xiao Xuanyu stopped and said, "the next one is the technology of light sail engine. We have already realized it, but there are also obvious shortcomings. Both the front engine propulsion technology and the technologies listed above have one thing in common, which is limited to short-distance travel and is inefficient. In terms of our light sail front propulsion engine technology, the longest voyage between Mars and the earth takes 100 days. According to the traditional propulsion mode, the speed is very fast. "

"But such speed and efficiency are still not the standard marks of K2 speed. How about further? What about Jupiter, Saturn, and even the Kuiper belt at the edge of the galaxy? How much time does it take to spend on the voyage? And there is a fatal weakness after the smooth sail is deployed. The front engine makes Mars Express unable to pass through the asteroid belt at all, which means it can only move in the asteroid belt. "

"Well, I'll listen, you go on." Ren Hongdao.

Xiao Xuanyu nodded and continued: "the above engine technology is basically unnecessary. I have two plans here, such as" hyperspace engine ". If the universe has more dimensions, does it mean that spaceships with" hyperspace engine "can fly through multidimensional space at high speed

Ren Hong shrugged and said, "hyperspace engine? It's almost incomprehensible under the system of laws of modern physics. "

"Indeed, then there are wormholes! However, this is the point to be considered for K3 civilization technology, not in the K2 standard speed category. " Xiao Xuanyu said, and then called up the last display panel, and said: "all the above can be ignored, but maybe we should pay attention to it - the technical imagination of erkubil engine!"

"Curvature engine?" Ren Hong looked curiously and had some ideas in his heart, but he had not yet said that he wanted to listen to the other party's views first and said, "what's your opinion on curvature engine?"

"Ercubier engine" is the so-called "curvature engine", also known as "curving engine".

This technology idea is well-known in the world, thanks to the warp speed engine of the enterprise in Star Trek.

Seeing Ren Hong saying this, Xiao Xuanyu thought for a moment and then said, "Er kubil engine, or meandering speed sailing, is to use the loopholes in the laws of physics to break the limit that the speed of light can't be exceeded to reach the speed of light.""However, there are many unavoidable problems with the ercubile engine. The most important thing is that the engine needs the so-called" strange matter "which has no known substance, which has negative mass and great negative pressure. What is the" strange matter "in the end Xiao Xuanyu shrugged and asked himself, "antimatter?"

He added: "apart from the so-called indispensable" strange matter ", one of the theories is that the energy required to maintain the" warp speed bubble "is more than the total energy of the universe according to the theoretical calculation. Meandering speed navigation will also generate a large number of radiation sources, threatening the safety of crew members. More importantly, is the so-called" strange matter "exist? Without this thing, we don't need to talk about curving, and we can't send signals in the curving state, which means that the crew can't control the spacecraft during the curving. I think even experienced crew members are not willing to drive this kind of spaceship. "

Xiao Xuanyu helplessly said: "the elkubil engine technology is the ideal K2 speed, but it is almost impossible to achieve."

"And more." Staring at the Star Trek star enterprise on the spotlight screen, Ren Hong said, "there is another point that is practical. Even the total energy output of the whole human society can't do the energy required to sail at warp speed, which determines that curving speed is too extravagant. What's more, a spaceship with an ercubile engine would be in an awkward position, faster than the speed of light, how many times the speed of light? tenfold? A hundred times? Not to mention the consumption of energy, how big is space? Even at 100 times the speed of light, it will take 1000 years to travel across the galaxy, let alone across galaxies. "
