Although the new space engine in the city of Mendeleev on the moon has not yet reached the extent envisaged.

But for use in the interior of the solar system, it is more than enough.

After all, the service life of lithium-carbon nanolayers is actually only a problem in a specific environment.

Navigating the inner solar system can completely increase the thickness of the lithium-carbon nanolayer, so as to extend the service life of the lithium-carbon nanolayer.

Therefore, after 37 days of trouble-free operation of this engine, the Space Division, the Space Defense Department, the Space Colonization Department, and the Earth Defense Department have joined forces to replace the engines and thrusters of all current spacecraft.

Since the moon belongs to the defense zone of the Ministry of Earth Defense, Maunggu directly dispatched five space warships and handed them to the city of Mendeleev to install new nuclear fusion engines and plasma thrusters on them.

For the 120,000-ton Qinglong-class space battleship, only one "Karl 1B" is needed.

Karl 1b is a nuclear fusion power system specially supplied for the internal use of the solar system, and the lithium-carbon nanolayer with a thickness of 3 times is enough to ensure the trouble-free operation of the nuclear fusion power system for 90~120 days.

The spacecraft will also be equipped with a spare lithium-carbon nanolayer that can be quickly replaced at any time.

In addition, according to simulation tests, spacecraft sailing inside the solar system do not need to use a speed of 6,000 kilometers per second at all, which is too cost-effective to use in the interior of the solar system.

According to the results of the simulation test, the ultimate speed of 200~1000 kilometers per second is the best ultimate speed of a spacecraft equipped with a nuclear fusion power system.

For example, from the earth to Venus, Mars, and Mercury, the speed of 200 kilometers per second is the most cost-effective, and the voyage only takes about 3~15 days.

Although you can use a speed of 1000 kilometers per second, but this speed is too cost-effective, the flight process, is completely accelerating and decelerating, for the manned spacecraft, continuous and violent acceleration and deceleration, the ride experience will be very bad.

The speeds of Jupiter, Saturn, Uranus, and Neptune are 400 kilometers per second, 500 kilometers per second, 600 kilometers per second, and 700 kilometers per second, respectively.

To Pluto and Cooper, it is 800~1000 kilometers per second.

This is a limit value calculated specifically based on the distance between the two planets.

Normally, these limits are constantly adjusted according to the distance between the two planets, ensuring the best value for money for the voyage.

The spacecraft sailing in the inner solar system, equipped with the Karl 1b, will not operate at full power, and under normal circumstances, will only turn on the nuclear fusion of 2~4 Levi's rings.

On the one hand, this can save fuel, and on the other hand, it can extend the overall service life of the lithium-carbon nanolayer of the powertrain.

In less than half a month, one of the Qinglong-class space battleships completed the upgrade.

This is the terrifying productivity of Homo sapiens, as long as the design of the product is determined, the transformation of the production line can be completed very quickly.

At present, the Karl-1b nuclear fusion power system production line in the city of Mendeleev on the moon can produce 50 Karl-1b units per month if it is running at full capacity.

After the Qinglong-class space battleship completed the upgrade of its power system, it was quickly pulled to the spaceport on the side of the base.

Considering the plasma thruster of the Karl 1B, the plasma tail flame it shoots out is very terrifying, basically no different from the particle cannon.

Therefore, this improved version of the Qinglong class, during takeoff, must pay attention to the direction of the nozzle of the thruster, if the nozzle is aimed at the equipment and facilities of the spaceport, it is very likely to cause unnecessary losses.

The management personnel in charge of the spaceport arranged a special inclined runway for the Qinglong class.

Captain Yin Siyong looked at the star chart.

At this time, the far side of the moon was facing the orbit of Mars, and he immediately ordered: "All of them, target Mars, go at full speed!" ”

"Roger."

The two Levi's rings in the power system quickly enter the state of nuclear fusion operation.

When the soldier in charge of controlling the thrusters pressed the start button, the thrusters began to eject aluminum ions that had been ionized into plasma.

The aluminum ions, which are accelerated to 15% of the speed of light, leave a cutting trail on the runway, and the blocking plate set up behind it is also densely packed with potholes.

If you aim at other spaceships, you can tear a hole in the spaceship in an instant.

Soon, under the impetus of the manic plasma, the Qinglong class slowly moved forward, and the speed became faster and faster.

In less than 100 seconds, the battleship flew down the ramp runway to the cosmos, the low gravity and atmosphere-free moon, which is very convenient for taking off large spacecraft.

It's just that as the Qinglong-class flew into space, the staff of the spaceport also controlled the robot and conducted a careful inspection of the runway.

The results are not encouraging.

The runway is cut by plasma with a very obvious crack, this crack reaches a depth of 4~6 cm and a width of 15 meters.

This situation basically means that the runway has been scrapped.

The person in charge of the spaceport hurriedly reported the situation.

But there is no way above, after all, the destruction of the runway by the ultra-high-speed plasma thruster is basically unsolvable.

The existing spaceport runways are all made of six-claw silicon steel or bio-silicate polymers, and no matter how good these materials are, they cannot withstand the impact of dense particles.

High-speed plasma thrusters are indispensable for the high-speed navigation of spacecraft.

The Development Research Divisions of several sectors, after discussions, have come up with some proposals.

For example, spacecraft landings equipped with high-speed plasma thrusters have been reduced, and special handover spacecraft have been adopted to be responsible for transportation between spacecraft and planets and space stations.

Those spaceports that need to land are specially equipped with exclusive runways, which have several requirements, the first is cheap, the second is disposable, and the third is convenient and quick maintenance.

After all, it is impossible to never land, and the Homo sapiens spacecraft needs to be overhauled once a year.

Of course, the company can also choose another option, which is to use the spaceyard, and arrange the annual maintenance of the spacecraft to be carried out in the spaceyard.

But now Homo sapiens has a very large number of spaceships, including 758 military warships and 9,673 civilian ships.

And it's skyrocketing every year.

However, there are only 3 space docks of Homo sapiens, and the remaining space shipyards and maintenance yards are all set up on the moons of the moon, Venus, Mars, and Jupiter.

Preparations must now be made to increase the size of the spaceyard on the one hand, and to renovate a number of specialized ground-based spaceports on the other to facilitate the landing of upgraded spacecraft.
