Movie black technology

In Chen Shen's view, there is nothing strange about whether it is the SLS or the Saturn V or the development of a new plasma thruster.

The only thing worth noting instead is the last-mentioned nuclear thermal rocket.

As the name suggests, this rocket is a nuclear-powered rocket.

It is different from the nuclear-powered rockets that many people have heard of, throwing nuclear bombs behind them and propelling the spacecraft with impact.

This kind of nuclear-powered rocket is more reliable, because it is equipped with a small nuclear reactor, and it does not drop nuclear bombs, at most it has a little nuclear radiation.

Chen Shen didn't know much about this kind of rocket, but after making a phone call, the relevant information was quickly sent to his computer.

This kind of rocket, as he had predicted before, was born during the space race of the last century, and only the tension at that time could give birth to this kind of thing.

At that time, both parties participating in the competition conducted research on this kind of nuclear thermal rocket, but in the end they all stopped at ground experiments.

Moreover, this thing was initially researched because it was worried that chemical fuel could not meet the propulsion needs of intercontinental missiles, and it was later transferred to the aerospace field.

For example, on the opposite side, research began in 1954, and it was transferred to aerospace applications after 1958. It was not until the closure of the Saturn rocket production line in 1969 that the research and development of nuclear thermal rockets basically entered a period of stagnation.

In the past ten years, although the experiments were only carried out on the ground, a lot of results have been achieved, and even a model that can theoretically be tested in the sky has been built.

Theoretically speaking, a nuclear thermal rocket is to place a small nuclear reactor on the rocket, use nuclear fuel as thermal energy to replace the combustion chamber of a traditional liquid rocket engine, and then let liquid hydrogen, liquid helium, liquid ammonia and other working fluids flow through the reactor to absorb them After the heat, it is ejected through the rocket nozzle.

Compared with traditional chemical fuel rockets, nuclear thermal rockets have two advantages: sufficient energy and strong carrying capacity.

Needless to say, the energy is sufficient. In the final analysis, the nuclear reactor used, even a small one, is enough.

In terms of delivery, taking the Mars payload as an example, a hydrogen-oxygen rocket with a carrying capacity of 140 tons in low-Earth orbit can only deliver 25 to 28 tons of payload to the surface of Mars.

And if this task is replaced by a nuclear thermal rocket with a near-earth load of 140 tons, it can theoretically reach 43 to 46 tons.

So in theory, a nuclear thermal rocket is indeed a rocket suitable for deep space exploration, if the system does not produce a plasma thruster that can be used in the atmosphere, and the citizens don't mind having a nuclear reactor flying above their heads .

By the way, it needs to be said that the uranium used in this nuclear thermal rocket is the same type as the mushroom bomb.

Moreover, the nuclear thermal rocket exploded directly during the ground test, but it did not cause a nuclear explosion.

At the same time, there have been other large and small leaks. When a reactor was activated during the test, liquid hydrogen flowed through the core and contacted the fuel rods at 2000°C. After power, the nuclear reactor structure was quickly destroyed, and the uranium dioxide and radioactive isotopes produced during fission were discharged into the atmosphere through the nozzle...

The danger of this thing is unquestionable, so at the end of the space race, it faded out of the stage of history along with the Saturn V without a single chance to go to the sky.

It was not until a few years ago that NASA launched the nuclear thermal rocket program again, and found a company from their country to help them develop the nuclear reactor and combustion needed for nuclear thermal rockets.

Now it seems that they may have really achieved results on nuclear thermal rockets.

After all, they have gained a lot of experience and experimental data in this field in the last century.

But want to rely on this to confront the Tibetan antelope?

Isn't it nuclear power?

Who wouldn't!

After the Tibetan Antelope is replaced with nuclear power, the voyage is more than 6 million kilometers. It can also go to Mars with a little power saving, and it also has a load of tens of tons.

sleep, rest!

The next day, Chen Shen went straight to the factory when he got up, and the work here was still in progress.

The Tibetan Antelope, which just came down from space yesterday, is being inspected here.

And its experimental loads inside have been taken out overnight, whether it is mice or vegetables have been sent to the laboratory environment for follow-up testing and observation.

Judging from yesterday's flight data, the interior of the Tibetan Antelope's cabin is quite well protected against space radiation. The radiation detector can't read the abnormal radiation value at all, just like on the ground.

If there are no problems with the vegetables and mice in the back, then the next flight can be replaced.

Of course, before that, the Tibetan antelope can fly into space a few more times in unmanned mode, and do a few more verifications to be the safest.

The inspection of the Tibetan antelope lasted for several days, and it was finally confirmed that there was no problem. After replenishing the energy, it was pulled to the launch site by the traction platform again for the second unmanned space flight. It was higher than last time, but the result remained unchanged, and the Tibetan Antelope still successfully completed the mission.

The difference is that this time the flight was not broadcast live to the outside world. Only the official sent a short text message after the flight test to inform the outside world of the second flight of the Tibetan Antelope.

So far, the outside world has truly believed in the performance of the Tibetan Antelope.

A spacecraft that can repeatedly carry people in and out of space has really been born in this world.

Many people feel that this is the real spaceship.

Some people even initiated a proposal on the Internet, thinking that compared to the Tibetan Antelope, the spacecraft that the public used to talk about before should be renamed the Space Manned Capsule.

This proposal also received the support of many people, and the response was enthusiastic for a while.

It's just that the space agencies of many countries have ignored it.

If the spaceship is renamed the Space Manned Capsule, wouldn't that mean that only one country in the world has a real spaceship?

Aren't they going to be downgraded for no reason?

Whoever likes to do this kind of thing that boosts other people's prestige, anyway, they don't do it.

At this time, in response to the news released by the opposite party a few days ago, a meeting was also held in China.

Chen Shen and a large group of other aerospace experts gathered together.

The people present are basically chief engineers, including the former chief engineer of the national manned spaceflight program, the original chief engineer of the national lunar exploration project, and the chief engineer of the national space station construction plan, and then there are some Mars exploration, rocket research and development the head teacher...

Of course, it also includes Chen Shen, the chief engineer of the 7,000-meter-level manned deep-diving large-scale underwater operation mecha project...

Chen Shen appeared in a group of chief teachers in charge of going to the sky, as the chief teacher in charge of going to the sea, which is also reasonable in theory. No matter how high the kite flies in the sky, there needs to be someone on the ground as the ballast stone, and he is the one ballast stone.
