Chapter 296

Among the "Kunlun Mountains", there are 21400 such small fusion engines, which are distributed in all directions of the Kunlun Mountains. This kind of design not only brings the superiority of mechanical structure, but also brings another advantage - the ability to bear risks is very strong.

Even if a part of the small engine of Kunlun Mountain is damaged, as long as the rest of the engine can be started, the spacecraft can still sail normally without losing its mobility.

These small-scale nuclear fusion devices are ready-made technologies of the earth civilization, and have been quite mature up to now. Compared with the previous large engines, it has higher utilization rate of nuclear fuel and can convert more mass into energy.

The huge energy generated by nuclear reaction, one part of the conversion will form high-energy micro blog through the special device in the engine room to propel the spacecraft, the other part is the traditional ion engine way, which will spray out the hot plasma stream.

Only the dual mode of microwave propulsion and plasma propulsion can make this one billion ton carrier have enough forward power.

"Is the last group back?" After carefully checking the parameters of each key part, Zhang Yuan asked his assistant.

The young assistant in the Secretary's office is Li Cheng, 43 years old, proficient in physics and mathematics. 43 years old is still the standard of young people in this era, but he is already one of the candidates for the vice captain of the Kunlun mountain. It has to be said that over the years of the whole civilization, talents have come forth in large numbers, elites have gathered, and many talents have been born.

"Report to the captain. They're all back."

Now that all the glitzers' affairs have come to an end, Zhang Yuan is also relieved, "then, six hours later, Kunlun Mountain, the first test flight officially begins!"

The captain's order was soon conveyed, and all kinds of staff on the ship were busy.

Of course, this voyage was just a test flight, and the carrier was not loaded with a lot of people and goods. In the first flight test, a large number of defects will be exposed during the voyage, and unified improvement is needed at that time.

Six hours later, the beautiful female reporter on the TV station is riding in a small spaceship for a live broadcast with both sound and emotion.

"The wandering project guides us to touch all kinds of civilizations Even though the road may be extremely bumpy, full of thorns, and may encounter a powerful enemy, we may face the risk of total annihilation... "

"But we won't regret it..."

More than 10 million people are on the surface witnessing the first trial of the carrier. The lively discussion and the voice of the TV station are interwoven.

With the passing of the last second, all of a sudden, the Milky light in the sky bloomed, covering all the noise. It's like the sudden appearance of more than 20000 small suns, completely illuminating the whole earth!

From the surface, the powerful plasma pulse marked a visible, tens of thousands of kilometers of fluorescent lamps.

The power of 21400 small engines is too strong. The camera is full of white light. Even the live reporter was stunned for a few seconds, and then she recalled the main thing, turned down the aperture of the camera, and began to popularize the common sense of microwave propulsion.

"Ah, after such a long distance, the temperature of our spacesuit still rose to 300 degrees centigrade This is a powerful little sun They are our latest engine technology, microwave engine. "

"The specific impulse of this energy engine is very high. It may have reached the extreme of conventional propulsion..."

"Let's compare the two ways of propulsion."

"The theoretical jet speed of traditional fusion engine can reach 20000 km / s. The backward speed of microwave is the speed of light, roughly 300000 km / s. It seems that the latter is more than 15 times higher than the impulse. Unfortunately, this kind of pure energy engine consumes a lot of energy. "

"The propulsion consumption of microwave engine is about 100 MW / N, and that of fusion propulsion is about 10 MW / N at the jet speed of 20000 km / s. The energy consumption of the microwave engine is 100 times that of the ion engine

"In fact, in a simple word, when the total energy and total mass ratio are fixed, the specific impulse has an optimal value, and the material utilization efficiency is the highest Therefore, the combination of the two engines can make the spacecraft achieve the highest mobility. "

"Of course, for very long-distance interstellar navigation, these two kinds of propulsion are just auxiliary means, because we have found a new kind of propulsion using the cosmic string of the universe itself New technology from the human branch of the golden sun

However, no one paid any attention to the popular science of the TV station. Engineers, scientists and students on the ground were all cheering enthusiastically for the first long-distance trial of "Kunlun Mountain".

"When I graduate from University, I can just get on the spaceship! Ha ha

"I really can't wait!"

A middle-aged man in his 100s said, "no, you know, interstellar voyage is really boring. Most of the time is spent in the void Sometimes I have to hibernate, but actually I'm not that happy. "The young man shook his head. "But don't you think this kind of Star Trek is very romantic? And we now have a new way to move forward It doesn't take a lifetime to get to another planet. "

"Thanks to the human beings of the golden sun, when will we send them information? Our development is also very good!"

……

In the "Kunlun Mountain" main control room, Zhang Yuan and others are also nervously observing the changes of various parameters in the spacecraft. To tell you the truth, because the tonnage of this spaceship is too large, it puts forward very high requirements for the properties of materials and the mechanical structure of the spaceship itself.

Therefore, most of the area of this spacecraft is composed of distributed structure. Because a single keel can't bear such a huge tonnage, Kunlun Mountain is not so much a super carrier as a combination of 36 Large spaceships!

The complexity of its navigation and the cooperation between them are far beyond the former "earth age"!

"Thanks to the productivity of 13 universal factories, it would be impossible to produce so many new materials in just a few decades." Zhang Yuan nervously looks at all kinds of data on the screen. Up to now, most of the commands are executed by artificial intelligence, and the part that human can operate is very small.

Kunlun mountain also uses biomaterials similar to the universal factory in some parts, especially in sensor locations.
