Chapter 494: Improvement Plan for NK Series Liquid Rocket Engines
"Professor Xu, I always thought you only studied physics, but I didn't expect you also studied aerospace?"
Xu You smiled and said, "Science is boundless. Moreover, the field of aerospace also contains a lot of physical knowledge. This is not surprising ."
"Yes, actually, I was originally a science major, and it was only during my graduate studies that I focused on the aerospace field. Professor Xu, what specific technology do you want to learn about today?"
"If possible, I would like to learn more about your country's liquid rocket engine technology."
"Professor Xu, of course there is no problem. Please rest assured that this time we are not just going through the motions, but are full of sincerity. If you have any questions, you can ask them at any time."
As he spoke, Nikolaski turned on the computer and found the corresponding information page.
It can be seen that Nikolaski was indeed very well prepared and had no intention of deliberately withholding any skills.
Xu You listened carefully to Nikolaski's explanation and asked some questions from time to time.
Through Xu You's questions, Nikolaski could see that Xu You was by no means just a layman in the aerospace field.
The level of professionalism in Xu Youti's questions is no less than that of professionals in the aerospace field.
There were even some questions that Nikolaski needed to think for a while before he could give Xu You an answer.
While talking with Nikolaski, Xu You sighed repeatedly, looking as if he had gained a lot.
"Professor Xu, if I didn't know your identity, I would definitely think that you were the chief engineer of your country's space agency. To be honest, exchanging knowledge with you is really a great test for me. I feel like my brain is about to be overloaded."
What Nikolaski said was true. After several hours of communication with Xu You, his whole body was already soaked in sweat.
These were the most mentally taxing hours in Nikolaski's life.
Even during the heavy space missions, he had never felt this way.
"Haha, high-intensity brainstorming does put a high load on the brain, but at the same time, it will also have a good exercise effect on the brain. Mr. Nicolaski, please take a break. It's time to eat."
"That's true. I feel a little hungry too." Nikolaski said with a smile.
After finishing the technical exchange, Nikolaski finally breathed a sigh of relief.
But what he didn't know was that Xu You didn't want to "let him go", he just wanted him to have a good rest first, as Xu You still had many questions to ask him later.
After dinner, Xu You pulled Nikolaski aside again and continued discussing the issues that had not been completed before.
Faced with Xu You's warm greeting, Nikolaski could not refuse the kindness and had to continue talking with Xu You.
"Mr. Nicolaski, the NK series liquid rocket engines here have a relatively light structure, and the combustion chamber pressure is very high, so we use a relatively high area ratio, right?"
"Yes, Professor Xu, it is for the reasons you mentioned that we adopted a high area ratio of 27 to 1, which allows it to generate very high sea level thrust and sea level specific impulse. The detailed parameters are all included here."
At this moment, Xu You seemed to suddenly think of something. Instead of looking at Nikolaski's computer screen, he opened the drawing software on his computer and started drawing something.
Nikolaski didn't know what Xu You was doing, but seeing how serious Xu You looked, he must be doing some important work, so he didn't ask, but waited quietly.
A few minutes later, Xu You finished his work and showed the screen to Nikolaski.
"Mr. Nicolaski, if we change the structure of the rocket liquid engine in this way, will it achieve better results?"
After seeing the picture on Xu You’s computer, Nikolaski was stunned at first.
Not to mention whether the new structure modified by Xu You is really feasible.
Just based on Xu You's drawing speed, it is enough to make people drop their jaws.
Although this is just a sketch, if Nikolaski were to do it himself, it would take at least half an hour to draw it to the same level.
In comparison, Xu You's speed is many times faster.
Then, Xu You explained to Nikolaski the reasons why he made such changes.
"If the structural design is adjusted in this way, the entire engine will have a stronger throttling ability. We can use an adjustable mixture ratio pump to control the relevant oxidizer and the fuel mixture ratio of the oxidizer and fuel . In this way, the combustion chamber pressure, sea level specific impulse, sea level thrust-to-mass ratio and other conditions can be kept within the best range."
Listening to Xu You's explanation, Nikolaski was also thinking hard.
A few minutes later, Nikolaski suddenly looked happy and shouted happily:
"That's right, Professor Xu! With your design, the structure of the entire engine will indeed be more optimized! You are indeed a rare cross-disciplinary talent in the world!"
"Mr. Nikolaski, you are too kind. If it weren't for your explanation today, I would not have thought of this way of structural optimization." Xu You said modestly.
After some communication, the Soviet scientists felt a little embarrassed.
Originally they were here to provide their own technology today, but in the end Xu You helped them come up with suggestions for technical improvements.
"Professor Xu, you have helped us a lot this time. We have been trying to further optimize the NK series of liquid rocket engines, but we have not found a suitable solution. I really don't know how to thank you!"
"Hey, don't be polite. We are the closest friends, and this is just a sudden idea. It seems that if we have the chance in the future, we should communicate more. This will also help the development of both of us."
Xu You's words were not just casual remarks, but had some purpose.
After seeing these big scenes, Xu You is no longer the simple person who only focused on scientific research.
If we can take this opportunity to learn more about the Soviet Union's cutting-edge technologies, it will obviously be more meaningful to the overall situation of the country.
Xu You himself can also acquire more knowledge and satisfy his thirst for knowledge.
And Xu You would not ask for it in vain. He could use his powerful brain to help them optimize some of their technologies.
This is a mutually beneficial and win-win situation for both parties.
"That's right! This is indeed something that will help the technological development of both of us!"
