When the Strait Space Launch Base was working overtime to build, Huang Mingzhe was not idle.

Inside the launch vehicle assembly plant in Tsu City.

Huang Mingzhe was discussing with Chen Yao, Li Guoqing, and John Field of the former British Interstellar Society.

At this time, they were in the virtual laboratory, and in front of them was a very rugged spaceship, codenamed "Daedalus". [Note: Daedalus was the builder of the Minoan Labyrinth in ancient Greek mythology.] ］

Daedalus is a fusion spacecraft designed by the British Interstellar Society in the 70s of the last century, and it is currently the only confirmed feasible spacecraft to cross galaxies.

Of course, the solution is feasible, but the engineering difficulty is very huge.

In 1978, the British Interstellar Society unveiled the final plan for the Daedalus program, which gave the first detailed design of a nuclear-powered spacecraft in history, with the aim of demonstrating the possibility.

The Daedalus is an unmanned interstellar research spacecraft, but the weight of this spacecraft is impressive, weighing 55,000 tons, of which 50,000 tons are the weight of fuel, and the weight of scientific instruments is only 500 tons.

And the spacecraft can only be assembled in orbit, looking at the ISS, which is only 300 tons, it took 20 years to assemble.

Even though the new human Chang-5-D has kept the launch cost down to a very considerable level, the Daedalus spacecraft is still very unfriendly in terms of engineering.

The reason why Huang Mingzhe chose the Daedalus solution is mainly because this plan is not technically difficult.

There are two types of nuclear fusion propulsion rockets, one is fusion direct injection and the other is nuclear photonic rocket.

The working principle of fusion direct injection rocket is as follows: nuclear fusion produces a large number of helium nuclei (alpha particles), protons, and electrons, which are sprayed out by magnetic field guidance, which can achieve high exhaust velocity and specific impulse, and the thrust and thrust-to-weight ratio produced is higher than that of nuclear power propulsion.

The Daedalus program uses deuterium and helium-3 as fusion fuel, and the fusion fuel ball composed of deuterium and helium-3 is ignited by a high-energy electron beam in an inertial confinement reaction chamber for fusion, and the ionic gas produced is discharged from the stern at a speed of 10,000 kilometers per second under the constraint of the magnetic field as a source of power.

Daedalus would need to consume 250 of these fuel balls per second, and the fusion thrusters envisioned by Daedalus could eject exhaust gas at about 15% of the speed of light in a vacuum.

Of course, Huang Mingzhe does not need the spacecraft to reach 15% of the speed of light, on the one hand, there is no need to carry out a transgalactic spacecraft for the time being, and on the other hand, 50,000 tons of deuterium and helium-3 are a proposition.

Deuterium is good to say, it can be refined in seawater, but helium-3 is a cheat, one kilogram of refining on the blue star is enough to choke, and there are more than 20,000 tons of helium-3, why not go to the sky?

The moon has millions of tons of reserves, but unfortunately the Illuminati occupy the land on it, and there are no conditions for mining at all.

"Huang, if you don't need a high-speed fusion spacecraft, the fuel can be reduced a lot." John Field said as he calculated the results using the rocket formula.

Huang Mingzhe, of course, knew that if the spacecraft didn't need too high speed, the fuel-to-load ratio could be much lower.

For example, accelerating the Daedalus spacecraft to 0.2% of the speed of light in a vacuum requires a fuel-to-load ratio of 0.029.

If the spacecraft is fully loaded with fuel, it is required to be able to accelerate from a standstill to 0.2% of the speed of light in a vacuum, and then decelerate to a standstill for at least 10 repetitions, the final fuel-to-load ratio is about 0.77.

That is, a spacecraft with a mass of 10,000 tons other than fuel must be able to carry 7,700 tons of nuclear fuel.

In fact, even 0.01% of the speed of light (30 km/s) is much faster than the first, second, and third cosmic speeds.

"Yellow, if you only ask for a maximum speed of 30 km/s, I can compress the fuel load ratio to 0.04, considering the endurance capacity, the final fuel load ratio is around 0.08 is the most suitable." John Field explained, pointing to the data.

Huang Mingzhe was satisfied with the final fuel load ratio data, he nodded and said:

"Directly using the small Jinwu nuclear fusion reactor, it can be transformed into a nuclear fusion direct injection engine."

"There are no problems with other components, we expect the overall weight of the spacecraft to be around 1,200 tons, which means we need 96 tons of nuclear fuel." Li Guoqing echoed.

Chen Yao shook his head and added: "No, Lao Li, you have forgotten the nuclear fuel needed by other nuclear fusion reactors, I estimate that it is about 100 tons!" ”

Huang Mingzhe turned over the current domestic deuterium reserves, and the advantage of the Jinwu nuclear fusion reactor is that there is no need for helium-3, and the nuclear fuel for the spacecraft only needs deuterium.

At present, the domestic deuterium reserves are divided into three parts, one part is about 1,600 tons of power generation reserves of the State Grid, one part is about 1,050 tons of strategic reserves of the War Committee, and the last part is about 342 tons of reserves of seawater desalination management companies.

Fortunately, due to the application of nuclear fusion reactors in recent years, there are very multiple hydrogen refining plants in China, plus heavy hydrogen extracted and separated by seawater desalination plants, so there are so many reserves.

Of the 1,600 tons of power generation reserves, up to 600 tons can be taken out, and the strategic reserves of the War Council and the reserves of the desalination management company combined, a total of 1,992 tons of heavy hydrogen.

Barely enough to use 20 ships, but of course Huang Mingzhe and the War Council's plan was to build 10 ships.

This is a reasonable arrangement that can be made at present.

Huang Mingzhe thought for a while and ordered: "Lao Li, you can complete the construction of the first batch of components as soon as possible, and you can launch the other three space launch centers into low earth orbit first." ”

"We're arranging, we've already done part of the main skeleton." Li Guoqing also knew that the situation was urgent.

"In addition, the assembly orbit is selected at a distance of 650 kilometers in low-earth orbit, and you have discussed it with various launch centers."

"No problem."

In fact, the aerospace field is one of the few fields within the new human race that has not withdrawn from the wartime mechanism, but on the contrary, the scale is snowballing.

A lot of manpower and material resources have been invested in the aerospace field, after all, in the war within the Blue Star Planet, the advantages of the new human race are very obvious.

And the war in outer space is what deserves the attention of the new mankind.

One by one, the Chang-5-D launch vehicles were built and then quickly put into service.

……

After internal discussions between the Scientific Committee and the War Committee, the project, codenamed "Huo Quai-class nuclear-powered space warship", officially began to be implemented within the new human race.

This class of space battleships will integrate the current top technology of the new human race to achieve the comprehensive defense of the new human race against the Blue Moon system, and remove the deadly threat of the Illuminati to the Blue Star.

Once the construction is complete, it will be the day when the new humanity and the Illuminati will reignite the flames of war.

Various supporting factories and enterprises have received a large number of orders for spare parts, which involves the cooperation of tens of thousands of factories.

In fact, the most troublesome part of building such a spaceship lies in the coordination of manpower and material resources.

And the cost of spare parts is very high, because a part is generally produced dozens of sets, at most hundreds of sets, and the production line is specially opened to generate dozens of sets of parts, which is a huge waste of manpower and material resources.

But there is no way now, the War Committee can be said to be pushing forward the construction of Huo Qu's disease at any cost.

Desalination plants and heavy hydrogen refinery plants along the coast are refining heavy hydrogen nuclear fuel at full capacity.

Under the wartime mechanism, the new humanity can do everything to make way for war in order to win, and under this sense of urgency, the new humanity has burst out with unprecedented productivity and cohesion.
