Humanity is missing, luckily I have billions of clones

To this day, Li Qingsong still only has the two landing spacecraft capable of traveling back and forth between Luoshen and the Deep Space Spacecraft.

Originally there was only one ship, but in the later stage of development, the parts of the dismantled first landing spacecraft were no longer used, so it was assembled again, and there were two ships.

In order to ensure that he does not lose these only two space vehicles, Li Qingsong has reduced their flight times as much as possible, and will not use them if possible, in order to extend their lifespans as much as possible.

But even so, today they are already very old and can only fly with difficulty.

Li Qingsong had been planning to develop his own aerospace capabilities for a long time, but due to insufficient basic technology and industrial strength, he had never been able to do so. At this moment, the base's scale and technological foundation had been greatly developed, and he could finally start working on it.

A large number of clones were put into an open space selected in advance, and soon an aerospace technology research base was built.

The first propulsion test then began.

Because the environment of Luoshen is completely different from that of the Earth, the aerospace technology developed on Luoshen is destined to be different from that on Earth.

On Earth, rockets are indispensable for sending spacecraft or satellites into space.

Because rockets cannot be made too large, spacecraft or satellites also cannot be made too large.

But here, Li Qingsong can skip the rocket step and directly build a flying vehicle that can take off from the surface of the planet into space and then return directly from space.

At the same time, on Earth, airplanes and spaceships are two completely different things. One can only fly in the atmosphere, and the other can only fly in space.

But on Roselle, the distinction between airplanes and spaceships cannot be so clear.

These two things can probably be considered the same thing - in any case, they both rely on the combustion of fuel to generate high-pressure gas and then spray it out, thereby gaining forward momentum.

Those with higher power and able to escape the gravitational field of Roselle are spaceships. Those with lower power and unable to escape are airplanes.

Essentially they are the same.

Therefore, in a huge factory building in the aerospace base, a large amount of methane and liquid oxygen were transported into the engine. After ignition, hot gas was ejected from the tail, and the huge kinetic energy immediately acted on the test bench.

The technology of this engine originated from the internal combustion engine technology that Li Qingsong had mastered long ago. There is only one difference: the internal combustion engine burns methane and liquid oxygen to push the piston, while here, the high-pressure gas generated by their combustion will be directly ejected.

Although the way work is done is different, the combustion process is the same.

The powerful spray lasted for several minutes. Looking at the readings on the screen, Li Qingsong frowned.

The power is too low, not enough to propel a spacecraft out of the gravitational field of a planet, or even propel an airplane to fly.

“We must improve combustion efficiency and scale.”

Li Qingsong thought secretly: "But if this happens, the temperature will be too high. I'm afraid the performance of my current heat-resistant materials can't withstand it."

This is a rather tricky question.

Of course, the human world has formulas for advanced heat-resistant materials, but they are not included in the Deep Space spacecraft's knowledge base.

There are high-performance heat-resistant materials on the Deep Space spacecraft, but Li Qingsong has seen them and found that they are too technically demanding and cannot be made by themselves.

"I still have to find a material with low technical content that I can make now but can meet current needs."

Li Qingsong's mind moved, and one thousand clones were immediately added to the materials building of the scientific research base.

Without any prior training or learning, the one thousand newly added clones immediately adapted to the work rhythm of the scientific research base and were integrated into the existing research and development work without any obstacles.

In addition to these 1,000 clones who were able to get started, Li Qingsong also mobilized the "brainpower" equivalent to approximately 3,000 people to analyze existing test data and think about future attempts.

There are many jobs that require people but do not actually require much brainpower.

It's like a clone driving an excavator. How much brainpower does it take to operate an excavator?

So a lot of brain power is freed up.

Since I have nothing to do anyway, I might as well use the time to think about materials science problems.

So there was such a strange sight in Li Qingsong's base:

Although a clone is operating an excavator, he is also thinking about the most cutting-edge and advanced materials science issues;

Although a clone is feeding pigs, he is also thinking about materials science issues;

Even a clone who is driving a train seems to be concentrating on operating the train, but in fact he is also thinking about materials science problems.

Moreover, if he encounters an emergency that requires all his efforts to deal with, he can immediately stop thinking about materials science problems, and the corresponding share of thinking may be instantly transferred to the head of another construction worker clone who is tying steel bars a thousand kilometers away.

By adopting this model, Li Qingsong achieved full utilization of the brain power of all controllable clones without any waste.

Li Qingsong was already very familiar with this mode. However, it was the first time that he suddenly mobilized a thousand clones to participate in the actual operation and an additional 3,000 brains to participate in thinking on such a large scale.

In fact, this issue is more important and must be resolved as quickly as possible.

Thousands of brains with knowledge from almost all subjects think about a problem at the same time, and breakthroughs soon appear.

After adding a certain proportion of nickel and tungsten metals and adopting a special metal treatment process, the heat-resistant metal that met Li Qingsong's requirements was finally manufactured and then quickly installed on the test equipment.

The advancement experiment began again.

This time, the flames shooting out from the tail of the engine were brighter and more violent, and it was clear that their temperature and pressure were higher.

Looking at the data on the screen, Li Qingsong nodded with satisfaction.

This time, the power finally reached the target.

The biggest problem in manufacturing aircraft is the engine. With the breakthrough of engine technology, it is not difficult to manufacture the iron shell.

Soon, a strange aircraft with a hemispherical shape and two jet nozzles on the lower plane and the rear appeared in front of Li Qingsong.

"ignition!"

Following Li Qingsong's command, the clone responsible for controlling the aircraft immediately pressed the corresponding button.

The next moment, blazing flames spurted out from the bottom of the aircraft, pushing the hemispherical aircraft, which had a diameter of eight meters and a height of four meters, to slowly rise into the air, eventually reaching a height of more than ten meters above the ground.
