Chapter 302

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

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

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

One part of the huge energy generated by nuclear reaction will form high-energy microwave through special devices in the engine room to promote the spacecraft, and the other part is the traditional ion engine to spray out the hot plasma flow.

Only the dual methods of microwave propulsion and plasma propulsion can give the billion ton Mothership enough driving power.

"Did the last group come 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, who is proficient in physics and mathematics. 43 is still the standard for 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 the whole civilization has been full of talents and elites for so many years, and many talents have been born.

"Report to the captain, they are all back."

Since all the matters of the Gliese 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 officially began!"

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

Of course, this voyage was just a test flight. The mother ship did not carry a large number of personnel and goods. The first test flight will inevitably expose a large number of defects during the voyage, which will need to be improved at that time.

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

"The wandering plan guides us to touch all kinds of civilizations... Even if the road may be extremely rough, full of exciting thorns, may encounter powerful enemies, and put us at risk of total destruction..."

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

About 10 million people are witnessing the first trial voyage of this Mothership on the surface. The lively discussion was intertwined with the voice of the TV station.

As the last second passed, suddenly, the Milky light burst out in the sky, covering up all the noise. It's like more than 20000 small suns suddenly appear, completely illuminating the whole earth!

From the surface, the powerful plasma pulse has drawn fluorescent lamps visible to the naked eye for tens of thousands of kilometers.

The power of 21400 small engines is so strong that the camera is full of white light. Even the live reporter was stunned for a few seconds. Then, she recalled her business, adjusted the aperture of the camera and began to popularize the common sense of microwave promotion.

"Ah, after such a long distance, the temperature of our spacesuit has risen to 300 degrees Celsius... These are powerful little suns... They are our latest engine technology, microwave engine."

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

"Let's compare the two propulsion methods."

"According to the traditional fusion engine theory, the maximum jet speed can reach 20000 km / s. The reverse thrust 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 Newton, and the fusion propulsion is about 10 MW Newton at the jet speed of 20000 km / s. At the same time, the energy consumption of microwave engine is 100 times that of ion engine! "

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

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

However, no one paid attention to the science popularization of TV stations. Engineers, scientists and students on the surface were all cheering enthusiastically and cheering the first long-distance test voyage of "Kunlun Mountain".

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

"I can't wait!"

A middle-aged man in his 100s said, "no, no, no, you know, interstellar voyage is actually a very boring thing. Most of the time is spent in the void... Sometimes I have to hibernate. In fact, I'm not so 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 of propulsion... It doesn't take a lifetime to reach another planet. "

"Thank the humans of the golden sun. When will we send messages to them? Our development is also very good!"

……

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 tell the truth, because the tonnage of the spacecraft is too large, it puts forward very high requirements for the properties of materials and the mechanical structure of the spacecraft itself.

Therefore, most areas of the spacecraft are composed of distributed structures. Because a single keel cannot bear such a huge tonnage, Kunlun Mountain is not so much a super carrier as a combination of 36 Large Spacecraft!

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

"Fortunately, there are 13 more universal factories, otherwise it is impossible to produce so many new materials in just a few decades." Zhang Yuan nervously looked at all kinds of data on the screen. Up to now, most commands are executed by artificial intelligence, and the part that humans can operate is very small.

"Kunlun Mountain" also uses biomaterials similar to universal factory in some parts, especially the sensor position.
