Although he had an idea, Cao Chuan was still skeptical that his idea could be put into practice, so he had to find a way to conduct a new round of rule simulation.

"The goal, to accelerate the orbit, through continuous acceleration, allows the spacecraft to gain an instantaneous speed of more than 100 km/s, so that it has a way to travel to more distant worlds."

"The basic requirements include having sufficient thresholds to facilitate manufacturing; The cost of guaranteed acceleration is lower than the use of fusion energy reactors; The acceleration should not be too large to avoid tearing apart the human body, or even the hull of the ship, during the acceleration. ”

The scale simulation soon gave several results, most of which were based on well-established electromagnetic propulsion theory, but unfortunately, a tragic scene after scene told him that the acceleration orbit based on electromagnetic propulsion was not so easy to build.

"First of all, there are a few technical difficulties—"

"In order to ensure the safety of the spacecraft and its crew, the acceleration must not exceed 20 m/s. This means that it takes 5,000 seconds of continuous acceleration for the spacecraft to complete the change from 0 m/s to 100 km/s. ”

"And in this way, if you take a first-stage acceleration, the acceleration orbit must be at least 100,000 kilometers long... Even if it is to gather the productive forces of the earth, it seems to be a super project of the Seven Wonders level, and it cannot be completed. ”

"In order to ensure sufficient acceleration, you have to have a large enough coil to maintain it in an ultra-low temperature environment, which will be easier to solve than the above problems."

This led Cao Chuan to see several environments, either the crew inside the spaceship died, or the accelerated orbit on the periphery of the planet was successfully built, and the human beings on the earth were instantly impoverished to the point that various resources were in a hurry.

"There's an alternative... Multi-stage acceleration, the acceleration track does not have to be a connected whole, it does not have to be a straight physical stick, it only needs to be a ring, which is enough to reduce the engineering volume by 90%. ”

"Even so, the deployment of so many rings is still huge, and how much does it cost?"

Cao Chuan's rule-based simulation is at a low point for the time being, and it seems that the acceleration orbit described in many science fiction novels, or the acceleration orbit that appears in the game, has led him to the wrong path.

"I don't know if there's any other way. Either way, it's okay to achieve my goals. ”

"Space elevators? This is to reduce the cost of aerospace, and it is of little significance for acceleration, and the space elevator has extremely high requirements for materials, all of which must be built with graphene, and the price is unimaginable. ”

"Sun sails? It is also to reduce costs, and it is even worse than a space elevator, because the acceleration effect is too poor, and it takes several years of acceleration to go to the asteroid belt, which is not practical at all. ”

It can be said that in the trough years of the aerospace industry after the end of the Cold War, mankind actually made few achievements in spaceflight, but many eye-catching theories and theories appeared, which can inspire people.

Not long after, Cao Chuan saw another one, "Trailer? Assuming that a small and medium-sized spacecraft is considered a carriage, if combined with a locomotive carrying a fusion energy reactor, it is enough to increase the speed of a small and medium-sized spacecraft to the lowest tolerable speed for interplanetary navigation of more than 100 km/s. ”

"If you adopt a trailer design, the cost is not high or low, and the advantage is that the trailer structure is simple and can be built in large quantities in a short time." After seeing this plan, he had a hunch that the trailer solution was the ideal solution to solve all the problems so far.

As for the existence of better ones, since time waits for no one, what Cao Chuan thinks of must not be a method that cannot be popularized and cannot be effective in a short period of time.

Even if it is hot for a while, it is enough to reverse their situation, so that the East Galaxy Company can stand at a higher starting point, and face the direct threat of the five hooligans with ease.

The original blueprint of building a Hengyue-class spaceship for the exploration department was once again dug out by him and placed in front of him, in essence, this special type of spaceship is also a towing spaceship, carrying a moon-class spaceship to sail around, which has a lot of reference value.

Later, after a day and a night of rule simulation, Cao Chuan had a more realistic drawing of the towing spacecraft in his hand.

It has a twin-engine structure, including two fusion energy reactors, which provides a stable power output, even if one breaks, the other can still operate; The spaceship is even larger, with a length of 140 meters, a width of 40 meters, and a height of 40 meters, like a coffin lying in the universe, enough to accommodate more than 10 small and medium-sized spaceships.

There are very few closed cabins in the hull, the front end is the captain's cabin, which is maintained by a crew of 20 people, and the rear is semi-closed in the rear to save materials and reduce process requirements, and also make the volume of the spacecraft expand again, more than twice that of the Hengyue-class spacecraft. As for the manufacturing products of the hauling spacecraft, at most no more than 5 billion, it is much cheaper than the Hengyue-class spacecraft, relying on the productivity of the lunar city, they have the means to make five or six hauling spaceships in half a year, and even, many countries on the earth can participate in the OEM, and the difficulty of popularization is quite low.

Although there are all the benefits of towing spaceships, Cao Chuan also knows that its use is at most near the planet, once it is more than 10 million kilometers away from the planet, it cannot be replenished, or it encounters a natural disaster**, the probability of an accident for those small and medium-sized spaceships with incomplete facilities will be several times that of large spaceships.

"I wonder if the Lighthouse Nation is interested in it?" Cao Chuan thought that it was originally a conspiracy to make this thing, and he didn't expect it to play any special value.

"If the Lighthouse Nation learns to make more... When the time comes, will you realize that all the customers are from other small countries? It's really worth playing. ”
