บท 294: Kunlun Mountain Trial
There are a total of 21,400 such small nuclear fusion engines in "Kunlun Mountain", and they are distributed in various locations in all directions of Kunlun Mountain. Such a design not only brings superiority in mechanical structure, but also brings another benefit—the ability to bear risks is very strong.
Even if part of it is damaged by the small engine of Kunlun Mountain, as long as the other parts can be started, the spacecraft can still sail normally without losing its mobility.
These small nuclear fusion devices are ready-made technologies of earth civilization, and they are quite mature now. It uses nuclear fuel more efficiently and converts more mass into energy than previous large engines.
The huge energy generated by the nuclear reaction will be converted into a high-energy microwave through the special device in the engine room to propel the spacecraft, and the other part will be the traditional ion engine method to eject the high-temperature scorching plasma stream.
Only the dual methods of microwave propulsion and plasma propulsion can give this billion-ton mothership enough power to move forward.
"Has the last batch of people returned?" After carefully checking the parameters of each key part, Zhang Yuan asked the assistant beside him.
The young assistant in the secretary's office is named Li Cheng, 43 years old, proficient in physics and mathematics, 43 years old is still the standard for young people in this era, but he is already one of the candidates for the deputy captain of the Kunlun Mountain. It has to be said that the entire civilization has produced talents in large numbers, a gathering of elites, and many geniuses have been born in so many years.
"Report to the captain, everyone is back."
Now that all the affairs of the Gliese people have come to an end, Zhang Yuan also breathed a sigh of relief, "Then, six hours later, the first test flight of the Kunlun Mountain will officially begin!"
The captain's order was quickly conveyed, and all the staff on the spaceship were busy.
Of course, this voyage was just a test flight, and the mothership did not carry a large number of people and cargo. For the first test flight, a large number of defects will inevitably be exposed during the voyage, and unified improvements will be needed at that time.
Six hours passed quickly, and the beautiful female reporter on the TV station was carrying out a live broadcast with a lot of emotion in a small spaceship.
"The Wandering Project guides us to touch all kinds of civilizations... Even though this journey may be extremely bumpy, full of thorns and thorns, we may encounter powerful enemies, and put us at risk of total annihilation..."
"But we won't regret it..."
About ten million people are witnessing the first trial voyage of this mothership on the surface. The sound of lively discussion and the voice of the TV station intertwined.
Suddenly, as the last second passed, a milky light burst into the sky, drowning all the commotion. It's as if more than 20,000 small suns suddenly appeared, completely illuminating the whole earth!
Seen from the surface, the powerful plasma pulses have drawn streaks of fluorescent lamps that are visible to the naked eye and stretch for tens of thousands of kilometers.
The power of 21,400 small engines is too strong, and the camera is already filled with a white glare. Even the lady reporter who was broadcasting the live broadcast was stunned for a few seconds, and then she recalled the business, turned down the aperture of the camera, and started to popularize the common sense of microwave propulsion.
"Ah, after such a long distance, the temperature of our space suits has risen to 300 degrees Celsius... These are all powerful little suns... They are our latest engine technology, microwave engines." "This kind of
energy The specific impulse of the engine is very high, and it may have reached the extreme of conventional propulsion..." "
Let's compare the two propulsion methods." "
The theoretical jet speed of a traditional nuclear fusion engine can reach a maximum of 20,000 km/s. Microwave's The speed of reverse thrust is the speed of light, which is roughly 300,000 km/s. It seems that the latter is more than 15 times higher than the rush, unfortunately, this type of pure energy engine consumes a lot of energy."
"The propulsion consumption of the microwave engine is about 100 megawatts/newton, and the fusion propulsion is about 10 megawatts/newton when the jet speed is 20,000 km/s. With the same propulsion force, the energy consumption of the microwave engine is 100 times that of the ion engine! "
In fact, it's just a simple sentence. The ratio of total energy and total mass must be low. The specific impulse has an optimal value, and the efficiency of material utilization is the highest... Therefore, the combination of the two engines can maximize the maneuverability of the spacecraft."
"Of course, for ultra-long-distance interstellar travel, these two kinds of propulsion are just an auxiliary means, because we have discovered a new cosmic string propulsion using the universe itself... a new technology from the human branch of the Golden Sun !"
However, no one paid any attention to the TV station's science popularization, and the engineers, scientists and students on the surface were all cheering enthusiastically, cheering for the first long-distance test flight of "Kunlun Mountain".
"When I graduate from university, I will be able to board the spaceship! Haha!"
"I really can't wait!"
A middle-aged man over a hundred years old said, "No, no, you should know that interstellar voyages are actually very boring. One thing. I have to spend most of my time in the void... Sometimes I have to hibernate, which is actually not that happy." The
young man shook his head, "But you don't think that this kind of interstellar travel Is it very romantic? And we now have a new way of propulsion... It doesn't take a lifetime to reach another planet." ""
Thanks to the humans on the Golden Sun, when we send them a message, our development will also not bad! "
...
In the main control room of "Kunlun Mountain", Zhang Yuan and others are also nervously observing the changes of various parameters in the spacecraft. To be honest, because the tonnage of this spacecraft is too large, the properties of the materials and the spacecraft The mechanical structure itself puts forward very high requirements.
Therefore, most of the areas of this spacecraft are composed of distributed structures. Because it is impossible for a single keel to bear such a huge tonnage, Kunlun Mountain is not so much a super mothership as it is a combination of 36 large spaceships!
The complexity of its navigation and the cooperation between them far surpassed the previous "Earth Times"!
"Fortunately, there are 13 more universal factories, otherwise it would be impossible to produce so many new materials in just a few decades." Zhang Yuan nervously looked at the various data on the screen. Most of the commands are executed by artificial intelligence, and the part that humans can operate is very small.
"Kunlun Mountain" also uses biomaterials similar to the universal factory in some parts, especially the sensor position.
