Just as Luo Feng and others were visiting the Kunpeng-level and Xinhang provincial-level construction.

Time came unconsciously, on March 13, 1 year of the new era.

In the spacecraft assembly factory in Jin City, Li Guoqing, Chen Yao and others are busy with the construction of Qianjian-2.

The Qianjian-2 is an enlarged version of the Qianjian-1, with an overall height of 105 meters, a full take-off load of 2,400 tons, and a payload of 600 tons.

The engine is still a nuclear-powered plasma engine, and this stage of the launch vehicle is the largest space rocket ever built by the new humans (the largest on the ground).

Several veteran engineers who have experienced the Cold War era, looking at the behemoth in front of them, think of the prototype of the Forward series of launch vehicles.

In the last century, there was a similar design, and the "Pluto" nuclear-powered cruise missile was designed by the United States before.

The Pluto nuclear-powered cruise missile uses a nuclear-powered ramjet engine and can cruise in the air for several months.

It can carry more than 20 mushroom eggs, and when attacking, it can fly tens of thousands of kilometers at a low altitude of 300 meters at three times the speed of sound, and its combat performance is simply incomparable.

As for why this product only stays on the design drawing, it is not that the engineering difficulty is difficult, but that I dare not build it, and I dare not use it if I build it.

First, the first stage of the rocket accelerates the thing to subsonic speed, the reactor ignition to 1400 degrees, subsonic air enters several conical heating chambers through the blades, expands and sprays backwards, giving thrust and cooling the core at the same time, driving the generator to store electricity.

Does it feel very similar to the nuclear-powered plasma engine developed by the new humans, there are only two differences between the two.

First, the reactors are different, Pluto uses a nuclear fission reactor, and the advanced series uses a nuclear fusion reactor.

Second, there is a difference in the way the working fluid is heated, Pluto is heated by direct contact, while the Advance series uses a nuclear fusion reactor to generate electricity ionization to heat compressed air.

Pluto's reactor is exposed and directly heats the air to propel it, and the cruise throws radioactive dust throughout, just think about how murderous this thing is.

In fact, the appearance of the "Pluto" nuclear-powered cruise missile was to deter Lao Maozi, who planned to cruise over the North Atlantic, constantly spraying radioactive dust and creating a polluted area.

Even after throwing all the mushroom eggs, it can continue to fly over enemy countries, creating a sonic boom and nuclear contamination.

Human beings are slaughtering their own kind, and they really do everything.

Humans during the Cold War and humans after that were simply two creatures, and the devil knows how many weapons of mass murder and murderous things they designed at that time.

For example, Lao Maozi's house, mushroom egg fire extinguishing, underground nuclear explosion power station, nuclear energy lighthouse, "Gorgon" interception system (nuclear explosion interception), Big Ivan hydrogen bomb, Poseidon nuclear-powered torpedo......

And Lao Mi's family is not far behind, the Orion space rocket, Pluto nuclear-powered cruise missile, nuclear-powered bomber, neutron bomb and cobalt bomb, etc.

The Daedalus Plan of Great Britain......

It was a time of depression and madness, the whole world was crazy, and it was a miracle that humanity was able to survive the Cold War.

It was by borrowing from these crazy plans of the last century that Li Guoqing and Chen Yao completed the Advance No. 1 and the enlarged version of the Advance No. 2.

"Lao Li, what do you think should be the design of the third advance?" Chen Yao asked.

Li Guoqing, the chief engineer of the construction of the Forward series and often tests new rockets, his opinion is very important.

After pondering for a few minutes, Li Guoqing spoke: "I think the third should end with a full load of 10,000 tons. ”

"Oh? Go on. ”

"You should know about space nanofactories and space mining."

Chen Yao nodded, he is engaged in aerospace, and naturally understands the sky factory and space mining of the new human race.

"With the exception of some equipment and food that cannot be produced and processed in outer space, our future outer space strategy should be inclined towards self-sufficiency and feedback to the Blue Star." Li Guoqing explained.

"That's true."

"In this case, our rocket design should have a degree, and I estimate that the payload is 2,000 tons, which is almost enough."

"Then take the maximum payload of 2,000 tons as the benchmark and design the last stage of the forward series."

The two set the tone and set this standard, in fact, because in the atmosphere of the Blue Star, the launch vehicle is less than 10,000 tons fully loaded, and the nuclear-powered plasma engine is the most cost-effective.

The weight is increased, the thrust requirements for the engine are very high, and the cost performance of the launch vehicle is too low, which is a bit more than worth the loss.

With the development of space factories and space mining, and in the future, Bluestar's launch vehicles will be mostly used for personnel transportation and food transportation.

Li Guoqing and Chen Yao naturally had to take precautions to avoid building a large number of super-large carrier rockets.

……

The Lagrange point L1 satellite city, the capsule and skeleton attached to the asteroid, has occupied the surface area of the asteroid.

In the orbit of 200,000 km ~ 260,000 km of the nearby Blue Star, 56 other asteroids are floating in this area.

On one of the semimetallic asteroids, numbered "T7", a "Luban" spacecraft is docked on it.

Countless nanobots have worked tirelessly inside the asteroid to collect the required elements, each of which is useful for new humans.

Therefore, the mining of a spaceship is a spaceship that specializes in collecting one or several elements.

For example, this Luban 008 is responsible for collecting copper, silver, zinc, and iron as an additive.

If the copper, silver, and zinc on the T7 asteroid are not enough for a ship, some iron will be mined.

There are two modes of transportation in the Lu class, the combination of the inner compartment and the external trailer, the inner compartment is 600~800 tons, and the external trailer is 1000~1500 tons.

The asteroids pushed by the Illuminati are all asteroids with a diameter of more than 400 meters, and they contain abundant raw materials.

If the raw material is not available to the asteroid, it will be mined on the moon, and if it is not available on the moon, it will be transported by the Blue Star ground, and then it will be impossible to find alternative materials.

New humans are gradually forming a system in this space mining and space factory.

……

Luban 008 completed the mining task and was pulled a 1,200-ton piece of iron towards a 180,000-kilometer orbit.

There is a space factory there, which was the fuse asteroid that strayed into the Blue Star, and was named the "Victory Asteroid" in honor of the Second Cleanup Battle.

More than three hours to fly.

The Luban 008 mining spacecraft docked at the spaceport of the Victory Asteroid.

The engineer and the person in charge of the plant, who recorded the type and weight of the minerals of Luban 008, took over the minerals.

On the assembly line of the capsule production workshop, industrial nanorobots perform their own duties, generating skeletons, radiation isolation layers, thermal insulation layers, thermal insulation layers, air liners, pipes, wires and cables, and mechanical structures.

Then it moves on to the next step, assembling various electronic devices or biocomputers, seals and pre-factory inspections.

The final livery is numbered and ready for delivery.

In the whole process, human beings only need to be responsible for a part of the detection and control equipment, and the convenience of production in the new era reflects the explosion of productivity.

It is this rapid production of space that allows new humans to build more and more satellite cities, spaceships, and space bases in outer space.

It also greatly reduces the logistical pressure, freeing up the hands of new humans to prepare for the march to Mars.
