I have a little black hole

As for the manufacturing work, Lei Tiantang is basically not involved. The current manufacturing capacity of Kuafu is already strong enough. All the 3 spaceships to be tested have a total of 6 Kuafu in less than two months. It's finished. If he made it, this test can be carried out long ago.

However, the spacecraft they want to test is mainly to verify whether the relevant design and technology are reasonable, and also to test whether the performance of products manufactured by industry can cope with the complex environment in the universe.

These data need to be verified after experiments to verify, so this test only built two spaceships, and did not follow their usual standard test process of manufacturing at least 4 ships at a time.

And not all of the three spacecraft tested this time are fully equipped, because some components do not need to be tested, and some have been verified by the laboratory on the space station. In order to save time, These components are not installed.

After all, this test is also the first test, there is no need to be so complicated, after the test, I don’t know how many places need to be changed. The more components are installed, the more troublesome it is to change them. These do not need testing It's not too late to wait for the components to be installed and tested when the design is roughly finalized.

"Did you say that the three spaceships we designed are a bit low?" After coming to the new underground base specially built for the spacecraft, Lei Tiantang saw the six universes standing quietly on the ground Spaceship, he couldn't help but spit.

It is true that the three spaceships in front of me seem to have nothing to do with the spaceships in those science fiction movies. The appearance is not beautiful except for the solidity of industrial manufacturing.

These three spaceships use two design schemes. One is an overall aircraft-like spaceship, except that it does not have the wings of an aircraft. Instead of wings, four units can be 360 ​​degrees back and forth, 120 degrees left and right Rotating super-large ion engine.

This design allows the spacecraft to fly more flexibly in space. After all, because there is no air resistance in space, it is difficult for the spacecraft to change the direction or emergency deceleration in flight. The propeller design can complete these operations better.

Of course, in order to have better propulsion acceleration, the spacecraft also has a larger ion engine at the rear to provide greater thrust.

Of course, the propellers on all types of spaceships use ion engines as the main propellers, because such propellers are the most cost-effective. It is unrealistic to use hydrogen or oxygen or other chemical fuels for long-distance space flight. of.

Resources such as hydrogen and oxygen are very important things in spacecraft. Without oxygen, astronauts cannot survive. The water synthesized by hydrogen and oxygen is also a necessity for astronauts. It is also a necessity for plants on the spaceship. Such an important thing Of course it can't be used as fuel so wasteful!

The most important thing is that the propulsion effect of chemical fuel is not ideal. The specific impulse is much worse than the ion engine. Lei Tiantang of course they will not choose this fuel engine. Besides, he and Kuafu also redesigned a new one. The more powerful ion engine is used for initial tests without any problems.

As for the more powerful engine in the future, it will be optimized and upgraded slowly in the subsequent research. Anyway, the research work of the spacecraft cannot be accomplished overnight.

The remaining two spaceships use a combination design method, but the design of the two models is also completely different.

The first one uses a spaceship design similar to that in "Interstellar Crossing". Of course, the design of Lei Tiantang cannot be exactly the same as the spaceship design in the movie, only the combination of it is used. Body design, and design that uses rotation to obtain gravity.

After all, if the development of their artificial gravity system cannot be completed in a short time in the future, they can only use this type of spaceship, because astronauts work in a gravity-free environment for a short time, but if they continue for several years Even if they work in a gravity-free environment for a longer period of time, their bodies will definitely be unbearable.

Therefore, in order to verify the feasibility of this technology, Kuafu and Lei Tiantang still designed such a spacecraft for experiments. Although they are not very optimistic about this design, after all, this design is really dangerous to sail in the harsh universe. too big.

You see, even the kind of rotating spacecraft with shields in "Space Traveler" almost collapsed after encountering an accident. If the protagonist opened a fierce operation, everyone on the ship would burp. Too.

It can be seen from this design that everyone subconsciously thinks that such a design is not reliable, but such a design may still be needed on the company's side in a short time, so it is not a big deal by the way.

After all, for the company's Mars colonization plan, the company's spacecraft design department has already carried out the initial design work for this type of spaceship. They just borrowed such a design to make an experiment, and it did not take much effort. What if something unexpected happens during the experiment? Wouldn’t it be better?

Although the remaining one is also designed in a combined way, this one actually prefers a type similar to modular design.

The entire spaceship is composed of 12 components with different functions and the core component in the center. From the appearance, it is a rectangular shape. It is no wonder that Lei Tiantang’s design of the spacecraft is very ugly.

The 12 components with different functions are mainly different in the general direction. Some key functions are available for each component, such as propellers, life support systems, food and water, including these functions such as various escape systems. But every component has it.

The advantage of this design is that when encountering irresistible dangers, such as catastrophic hazards such as asteroid impact, the spacecraft can escape from the damaged spacecraft without any damaged components, and provide maximum safety for astronauts’ lives. Protection.

Such an escape design is much better than using the small escape capsule alone. The escape capsule design can only maintain the life of astronauts for up to one month. If there is no spaceship to rescue at this time, it is still It's cool.
