Chapter 1217 We Are Not Joking
Magnetic fluid power generation is not a new term created by Chang Haonan himself.
In fact, this concept was created quite early, and can even be traced back to Michael Faraday, the founder of electrodynamics.
The first patent for magnetic fluid power generation was also landed in the United States in 1910.
And then...
There was nothing else.
Although the theory is very rich, in the nearly century that followed, humans have never been able to master reliable technical means to produce high-speed plasma.
It was not until the beginning of the 21st century that humans built a practical magnetic fluid power generation verification device for the first time.
Although it is called a device, in fact, due to the strength and speed of the magnetic fluid, the scale and power generation are still very small.
It is closer to some kind of toy.
If it is just like this, it would be fine.
After all, it is the first time that humans have achieved nuclear power generation, and the power is also not enough to light a light bulb.
The key is that it seems that there is no prospect of further breakthroughs in the short term.
In short, even in the industry, it can't cause much trouble.
So after hearing Chang Haonan's answer, Jiang Zonglin did not immediately think about the application direction.
Instead, he started to think about how to weaken this effect:
"So, as long as the magnetic fluid no longer cuts the magnetic flux lines, there will be no induced potential?"
Chang Haonan's proposal just now is exactly the same:
"That's right."
He nodded:
"The magnetic field of the equipment and the geomagnetic field are roughly horizontal to the ground and are in an east-west direction, so the normal wind tunnel operation process will not have any problems... But after adding the gas circulation facility, the flow direction of the magnetic fluid will change, resulting in a loss of some energy..."
"In fact, the simple loss of energy is not a big deal. I am worried that the gas flow rate you have produced is too fast, and the induced potential difference is too large, which poses a risk to the equipment itself..."
The last sentence is obviously a bit joking.
Let alone the total airflow temperature of 8000K, even if the airflow temperature really reaches 8000K, it is not enough to completely ionize the working gas mainly composed of nitrogen and oxygen, and it is even more impossible to achieve the conductivity of 10^6 S/m of solid metal.
If it is so easy to cause danger, then the magnetic fluid power generation technology will not be ignored for decades.
What's more, the wind tunnel itself is installed in a strictly grounded way, so even if there is a voltage of hundreds or thousands of volts, it will not really damage the equipment itself.
Jiang Zonglin on the other end of the phone could naturally hear it, and immediately laughed heartily:
"Don't worry, Mr. Chang, after each test, we will check the structural safety of the equipment in all aspects to ensure that all risks are nipped in the bud!"
"Well, I'll wait for your good news!"
The JF14 wind tunnel is the top priority of the current mechanics work, so Chang Haonan didn't talk too much about other things with Jiang Zonglin. After routine encouragement, he ended the call.
But after putting down the receiver, he immediately took out a notebook from the drawer on the right side of the desk.
The leather cover has been marked by many traces of time, and the side of the book is almost completely stained black because of frequent flipping.
It is not difficult to see that it has been used for quite some time.
This was purchased by Chang Haonan from a stationery store in Beijing University of Aeronautics and Astronautics not long after his rebirth.
Used to record some inspirations or ideas that are not yet available for research and development, but will be useful in the future.
He opened the notebook and wrote a title on the top of a blank page:
Detonation-driven magnetohydrodynamic power generation-
At least 90% of the difficulty of magnetohydrodynamic power generation comes from how to generate high-energy airflow with sufficient speed and conductivity.
The detonation-driven technology derived from the ultra-high-speed wind tunnel can just meet this requirement.
Of course, it can only produce a moment of no more than 0.01 seconds.
It is a pipe dream to want to use it on normal power generation equipment.
But what if... it happens to be a pulse power supply?
The most important pulse power supply at present is a capacitor power supply that stores energy in the form of an electric field.
But electric field energy storage has extremely high performance requirements for high-power intermediate energy storage components, and often has extremely exaggerated volume and cost.
Taking a capacitor pulse power supply as an example, if you want to achieve an energy storage of more than 100MJ, then the capacitor alone will reach an astonishing volume of about 100 cubic meters.
And it is still growing exponentially.
As for mechanical means such as flywheel energy storage and gravity energy storage, due to the problem of conversion efficiency, the upper limit is too low and is often more suitable for steady-state power supply.
However, the magnetohydrodynamic generator, which does not require high-power switches, has no rotating parts, and can directly transfer energy to the load, does not have these concerns.
It can be used in situations where it is inconvenient to use capacitor/inductor energy storage...
Chang Haonan wrote furiously and soon filled a whole page of the notebook.
After stopping to think for a moment, he put four asterisks at the bottom.
Priority four stars.
That is, do not start research and development at the moment, but invest resources in it immediately after objective conditions allow...
...
Just as Chang Haonan was writing furiously.
Hundreds of meters away, the Gaofa factory area.
A row of four Coaster minibuses rushed in, led by two small cars, and finally stopped in a row at the door of a workshop.
Originally, this should be the loading and unloading area for raw materials and products. Passenger vehicles are generally not allowed to stop here, so as not to affect the efficiency of the operation or even cause danger.
But today's situation is obviously not ordinary.
Almost at the same time when the convoys stopped one after another, a team of about 30 people also walked out of the workshop not far away.
The two people in the middle of the crowd, one is Ren Bingda, the deputy general manager of Gaofa Group, who obviously appeared as the host representative.
The other one has a white face and a pass hanging around his neck.
It is Tim Bodie from Rolls-Royce.
To some extent, he is an old acquaintance with Ren Bingda.
Today's visit was specially arranged by the latter.
In fact, Bodie received a request from his immediate superior about half a year ago, asking him to contact the Chinese side on the next stage of aviation engine emission standards.
But on the one hand, after the crisis of Trent 900 ended, Bodie, or the entire Rolls-Royce, also restored the traditional efficiency of being a British.
On the other hand, Bodi had just taken over the New Generation Medium Thrust Turbofan Engine (NGME) project. He had not had time to understand many situations for the first time as the team leader, and he was indeed unable to leave for a while.
So until now, when the third quarter of 2005 was almost over, he finally made this trip.
Fortunately, after publishing that harshly worded press release, China has not made any public statements on the issue of aviation emissions.
It seems to have really verified the previous conjecture that the press release was to cooperate with the public opinion offensive launched against the United States at the IPCC conference.
At least in Bodi's opinion, he should not have delayed anything.
Especially after arriving in Gaojing this time, Ren Bingda, who was in charge of the reception, changed his aggressive style in the UK and received him with extremely high standards.
He even arranged to visit one of the core production workshops of Gaofa Group.
That is the place where turbine blades for Trent 900 are processed.
Although this kind of cursory inspection can't tell anything, and many of the core processes are obviously temporarily suspended.
But letting him in is a gesture of friendship and mutual trust.
In short, Bodi's mentality at this time is still quite relaxed.
"Ren, although our cooperation has lasted for several years, this is the first time I have seen your production process with my own eyes. To be honest, it is very unexpected..."
After getting in the car, Bodi gave a very sincere compliment on this trip.
"No, no."
Ren Bingda then sat opposite him and waved his hand modestly:
"Compared with old-fashioned companies like you, there is still a lot to learn."
This is not entirely polite.
With the continuous improvement of the level of Gaofa Group in recent years, especially after the AE1500/Turbofan 20 project was established, he can feel more and more that although China has many unique skills in the field of aeroengine technology, there is still a lot of room for improvement in the accumulation of hard power, especially in the fields of production and management.
Including this meeting with Bodi, it was also in accordance with Chang Haonan's previous arrangement to strive for cooperation with Rolls-Royce to further fill the gap in entering the civil aviation engine industry.
After a round of greetings, Bodi couldn't stand Ren Bingda's constant avoidance of the topic, and took the lead in getting to the point:
"Ren, I remember you released a news at the beginning of the year, saying that you would reduce cruising fuel consumption by 8% and exhaust emissions by 16% to 30% based on the CAEP6 emission standards?"
Because he had just judged that the Chinese side was most likely bluffing, so this time he only mentioned it in a casual tone.
But after listening to Ren Bingda, he first smiled, and then nodded very solemnly:
"That's right."
