That's amazing! That's a lot of thrust for a small-thrust Hall thruster!
A great ancient Greek mathematician and physicist once said: "Give me a fulcrum, and I will be able to pry up the whole earth!" .
In the past, such comments would have attracted criticism and ridicule.
But in the present 21st century, China has confirmed this conclusion at the space launch site.
What kind of technology is this?
Why, you may ask, should we use such a small engine?
First, we need to know a few things about rocket launches.
The chemical fuel we see in conventional rockets has a fatal drawback.
That is -- consuming and inefficient.
Therefore, in order to solve the problem of inefficiency, the rocket was designed as a multi-stage form 39bet-xsmb-xổ số tây ninh-xổ số binh phước-xổ số binh dương-xổ số đồng nai.
Each stage of the rocket is loaded with engines and fuel.
Starting with the initial stage at the end of the rocket, each stage of rocket fuel, when exhausted, automatically falls off.
In this way, to reduce the load of the rocket in the flight process, so that the rocket can accelerate forward.
Isn't it amazing to see this?
With the untiring efforts of our scientists, more amazing technology has been born!
In 2021, China's Long March-5B-Yao2 carrier rocket launched the first module of the space station.
In the future, the mass of China's space station will reach a staggering tens of tons!
You might wonder how much force it would take to push ten tons of weight.
Let alone in space!
However, the engine thrust needed to maintain orbit adjustment and propel the above space station is only 80 mg!
With such a small force, it can only hold A4 paper.
It uses a new particle accelerator instead of traditional rocket chemical fuel!
So how does it generate such a powerful thrust?
It turns out that it uses electrons to bombard atoms to create ions, which in turn accelerate and squirt backwards to gain thrust.
It shoots ten times faster than chemical fuel!
But the fuel is a tenth of the mass of the chemical fuel!
It is an efficient solution to the traditional rocket fuel load problem!
But scientists are trying to improve its efficiency and longevity.
The Hall effect is used to improve the problems that may occur.
So it's also called a Hall thruster.
This is where we can answer the question above.
Why would we use a Hall thruster with so little thrust?
That's because Hall thrusters accelerate particles to a very high speed.
This creates a large specific impulse (the amount of thrust that can be produced per unit mass of working fluid).
But there's a problem, because we're working at the atomic level. Less ion mass is ejected per unit time. So you have less thrust.
But in space, it's home!
The drag caused by friction between the space station and the thin atmosphere of near-Earth space.
It lowers the orbital altitude.
And because the space station is weightless in space.
A small thrust can also cause the space station to accelerate.
So as to achieve the magic effect of "four two dial thousand jin".
Such a steady and efficient way to push.
Under the unremitting efforts of our scientists and the intrepid spirit of exploration.
The Hall thruster has become the country's rocket fuel of choice!
