In fact, it is not just ordinary people in the United States who want to know the propulsion system used by the Xinghai. NASA itself also wants to find out what the working fluid is in the red-purple tail flame.
And about this, they have no clue.
Twelve hours have passed since the launch of Xinghai. As the expert said at the press conference, NASA has compared almost all electric propulsion media, but has not found any.
The color of the tail flame of the seed material is reddish purple.
What's even more confusing to them is how electric propulsion can achieve such huge thrust.
........
On the other side, while the Xinghai was still sailing in outer space to complete experiments, and while Chinese netizens were still excited about their breakthroughs in the aerospace field, a piece of news was spread across the sea and was introduced from the outside network by thoughtful people.
"The Xinghai is suspected not to use an electric propulsion system, or its essence is still traditional fuel propulsion!"
The source of this news comes from ABC broadcast media, which is one of the three major television networks in the United States and is headquartered in New York City. Its influence is quite large.
When you click on the news, the content is a press conference from the NASA headquarters, as well as the evaluation and speculation of the Xinghai propulsion system by a NASA spokesperson. Including the two tail flame comparison pictures displayed by NASA at the press conference, they are also the same.
and was included in the news.
Under the deliberate guidance of some caring people, this news quickly became a hot search topic and was seen by many surfing netizens.
This piece of news poured cold water on many netizens who were still excited, celebrating the extreme development of their own aerospace field and the imminent prospect of surpassing the United States.
In the news report, "ABC Broadcast Media" not only reported the analysis of the NASA space agency, but also further filled in and processed NASA's speculation.
In addition, reporters from "ABC Broadcast Media" also interviewed experts and professors in the aerospace fields such as Space-X, Blue Origin, Orbital Science, etc. It is not just NASA experts who are confused about the fact that Xinghai uses an electric propulsion system
, other experts and professors in the US aerospace field also have doubts about this.
The difference in the propeller tail flame of the Xinghai space shuttle in the atmosphere and in outer space is the biggest doubt and problem.
As soon as this news report was released, it sparked extensive discussions on Twitter, Facebook and other social media.
Many Americans feel that the analysis of aerospace companies such as NASA and Space-X is very reasonable.
If it were possible to achieve electric propulsion into the sky, the tail flames with completely different colors at both ends would be completely unexplainable.
When this report was sent back to China, it sparked a heated discussion, and the related topic was quickly trending on websites such as scarves and βhu.
[Not electric propulsion? Is it a combination of electric propulsion and chemical fuel engine? 】
[Hey, I'm so happy, I really thought the electric propulsion system had a breakthrough. 】
[Laughing, I said it was impossible a long time ago. What even a major aerospace country like the United States cannot do, but Professor Xu can do it? You are just being deceived. 】
[Where are the people who were still clamoring to surpass the United States in the aerospace field yesterday and today? Why are they all gone now? The United States did it with fossil-fueled space shuttles in the last century.]
[Go to sleep, the gap in the aerospace field cannot be smoothed out by one person.]
[These shepherd dogs upstairs are really interesting. Why, if you lick your rice daddy like this, can it give you rice gold? Even if it is a combination of electric propulsion and fossil fuel engines, that is our pride. Can Xinghai not
If you need an external thruster to break through the gravity well, can your Mi Daddy's space shuttle do it?】
[Happy, you may not know the significance of a space shuttle that can freely navigate within the atmosphere and outer space orbits. Is this an ordinary space shuttle? This is an aerospace plane!]
.......
The hot discussion is not just about the scarf. As time goes by and the news ferments, some bloggers in the aerospace field have further analyzed the Xinghai.
Some people think that Xinghai uses electric propulsion engines from beginning to end, but it is just because the power required in the atmosphere and in outer space are different, and the working fluids used are also different.
The red-purple working fluid present in the atmosphere can provide huge thrust for climbing the gravity well. After reaching outer space, because there is no influence of air resistance and gravity, there is naturally no need for such huge thrust for control.
In contrast, using a working medium with smaller thrust to complete activities and orbit changes in outer space is easier to control.
After all, short-distance space activities and experiments do not require extreme speed like interstellar travel.
Others believe that the Xinghai uses traditional fossil fuel engines for propulsion and switches to an electric propulsion system only after climbing the gravity well. They believe that the Xinghai Research Institute has packed two sets of engines into a space shuttle.
The news reports of "ABC Broadcast Media" were also quoted by it. The opinions of giants in the aerospace field such as NASA, Space-X, and Blue Origin are enough to influence a group of people.
After all, the strength of the United States in the aerospace field is deeply rooted in the hearts of the people. Since the red and blue Cold War of the last century, no country has been able to catch up with the other country.
Not only that, these bloggers listed various high-propulsion-efficiency refrigerants currently used in electric propulsion engines, but none of them can match the flame color of the Xinghai that sails in the atmosphere.
On the contrary, among traditional chemical fuels, there are many high-propulsion fuels whose flame color is red or purple.
The tail flames of the Xinghai space shuttle's thrusters in the atmosphere and outer space conform to this characteristic.
In addition, it is also a huge doubt whether electric propulsion is really capable of sending a space shuttle weighing dozens or even hundreds of tons into the sky.
After all, previously, the thrust of the world's most powerful electric propulsion system was only about 5N.
This chapter is not over yet, please click on the next page to continue reading! The thrust of 5 N can only theoretically send an egg into outer space, and it is still theoretical. In fact, it is far from possible.
Now, Xinghai must weigh not only one hundred tons, but thirty or fifty tons. It is impossible to send such a heavy space shuttle into the sky based on the electric propulsion technology of this era.
.......
On the other side, in Xinghai Research Institute.
Although Xu Chuan does not use the Internet much when he is busy, when it comes to the development of fields such as space shuttles, he will still browse the opinions of major media in various countries.
He almost laughed out loud when he saw the news from NASA's press conference and ABC radio and other media.
Has NASA run out of tricks? Or is it so anxious to regain its reputation in the aerospace field that it even held such a press conference?
But looking back and thinking about it, it seems to make some sense.
Theoretically speaking, there is indeed no problem with the analysis of NASA and some bloggers.
The thrust of the electric propulsion engine has been pushed from N level to KN level. The leap is so large that it is simply unbelievable.
Before the aerospace engine matured, not to mention NASA, many senior executives in China who knew about the breakthrough of small reactors did not believe that the aerospace engine could break through so quickly.
After all, the difference from a few N to hundreds of KN is not a difference of ten or a hundred times, but a gap of tens of thousands of times.
But sometimes the maturity of a technology can drive far beyond its own field.
Just like the maturity of controllable nuclear fusion technology, it has driven the development of far more than just the energy field.
Whether it is the application of high-temperature plasma turbulence, the development of superconducting materials, or the construction of spiral magnetic fields, etc., all have been greatly improved.
And aerospace engines, in this environment, can naturally develop more violently.
In addition, one of the reasons why the aerospace field has never paid much attention to the research of electric propulsion systems.
In the past, the biggest use of electric propulsion engines was in equipment such as satellites and space stations.
Because these devices are in space, there is no interference from air resistance and gravity, so the requirements for propulsion power and functional systems are not high.
Most of the time, the power generated by a solar panel and a lithium battery is enough for a Hall thruster or other electric propulsion engine.
NASA experts probably have a hard time imagining an aerospace engine that consumes as much power as a small or medium-sized thermal power station; it’s also hard to imagine an electric propulsion that can use air as the propellant.
What is the system like?
After all, this is more than a slight technological advance.
Even overtaking in corners is not enough to describe Xinghai's lead!
After all, the United States has not even kept up with the technology of large-scale controllable nuclear fusion reactors, let alone small fusion reactors that are more difficult on this basis.
Without a small reactor, the aerospace engine would only be an ideal design, and it would be impossible to provide huge thrust to propel the Xinghai into space.
If you are half a step ahead, you can catch up; if you are one step ahead, you can speculate; if you are two steps or three steps ahead, you can look up.
But when leading technology cannot even speculate, then there is only despair.
