"How did you come up with this formula? The premise of this derivation process is that there is only one variable in the factor. When δ is not determined, this formula is completely invalid!"
In a huge auditorium, hundreds of scientific researchers over fifty gathered together.
Probably they could never have imagined that these cutting-edge talents who were originally scattered across the country and had never had a chance to get together in this life would actually be in one place because of the young man on the podium.
The commander of the Second Artillery was sitting at the front. He was not wearing a military uniform today, but was wearing a neat Mao suit.
He couldn't understand what Lin Zhuo just said on the podium. Those things were too profound, and the process of pushing them down even made people drowsy.
However, he did not do this. The reason was not that what Lin Biao said was profound and simple. On the contrary, what Lin Biao said was more boring than when he studied at the military academy. However, he was extremely excited at this time. .
Because he likes to watch other people argue.
Just like countless Chinese people with bad traits.
This was the first day of Lin Zhuang's class. Obviously, it was difficult for the Second Artillery scientists who had spent their whole lives dealing with nuclear physics and missile knowledge to sit down and listen to the guy in front of them who had not even grown hair yet. I'm talking nonsense here. After all, any of them are ruthless people who can be doctoral supervisors in the top 985 universities in the country. Among them are several academicians of the Chinese Academy of Sciences. If you don't show some real skills, you want to convince them. It's really hard to convince them. It is as difficult as climbing to the sky.
Lin Biao only scrawled three formulas on the blackboard, and then a commotion began below.
They can all understand the first formula. It is the basic formula of all missile power systems. This formula is not complicated. Nowadays, as long as graduate students studying in this professional field, nine out of ten will use this formula as a subsequent derivation. Basic formula.
The second formula is different, or in other words, the derivation based on that basic formula has a different direction from other existing derivation, but most of the scientists present can understand the direction of Lin Biao's research.
As the saying goes, laymen only watch the fun, experts watch the door. Although some variables still need to be manually checked in the derivation of this step of the formula, and even exhaustive methods are needed to judge the correctness of Lin Biao’s derivation formula, but since Lin Biao wrote it, there must be his grasp.
So after the second formula came out, although there was some commotion, fortunately with the reserve of scientists, these old guys did not put forward their opinions.
However, the third new formula derived based on Formula No. 2 is really too whimsical and even seems a bit desperate and nonsense, which makes people have to doubt the rigor of Lin Biao's derivation.
The person who just asked the question had some gray hair and looked to be at least over sixty years old. He looked excited at this time and had an unhealthy blush on his face. He probably had a lot of opinions on this part of Lin Biao's derivation process.
The people around him responded with understanding, while at the same time they were full of contempt for Lin Biao on the podium.
This scientist named Feng has been immersed in rocket power, especially in the combustion of accelerant for more than thirty years. No one present has a deeper understanding of this aspect than he does. It is no exaggeration to say that without him, , the country’s missiles cannot fly so far.
Therefore, he was particularly angry at Lin Biao's nonsense, which was also mixed with dissatisfaction with the Second Artillery Commander's random command. He stood up and directly raised his doubts.
"δ does not need to be determined in the first place, because countless derivation has proved that this variable is unmeasurable." Lin Biao glanced at the other party and pushed up the glasses on the bridge of his nose.
"Science requires rigor! If you don't calculate this variable clearly, the formula you come up with must be wrong. Then if you really apply it, aren't you afraid that the rocket engine will turn into a bomb that may explode at any time?!" Lao Feng raised the The knuckles of his hands turned white from his grip.
"It is precisely because of this that we have now made the rocket so huge so that the combustion chamber of the rocket will not turn into a big bomb. But have you ever thought about the process loss of such a large engine? It will reach a terrifying level. Degree."
Process loss is actually equivalent to the excess part in the thermal conversion process.
For example, when a car is filled with gas and all conditions remain unchanged, a basic parameter of the car will be given. The source of this parameter generally refers to controlling all the variables of the car so that it is empty on the test line. Earned from transfer.
This will give you the fuel consumption per 100 kilometers of the car.
But in fact, when actually running on the road, the car is often unable to achieve the fuel consumption specified in the parameters due to various reasons such as road conditions and car load. The difference between these is the origin of process loss in Lin Bian's mouth.
Of course, this is just an example. In fact, from the combustion of gasoline to the start of the rotation of the four wheels, the process itself also involves kinetic energy loss, which is even related to the friction of the tires, road conditions, etc.
"We can now reduce the 'process loss' you call it to less than five percent, so your formula is meaningless."
When Lao Feng heard the words "process loss", he couldn't help but sneer at Lin Bian even more. It turned out that he was a junior brother who didn't even understand basic terms. He didn't know what the headquarters was thinking, and he actually let such a loser give these things. Scientists take classes.
What he didn't know was that the reason why Lin Zhuo said this was actually for the Second Artillery Commander below the stage.
"Although δ is unmeasurable, this variable can be controlled within a range. As long as it is within this range, it is impossible for the engine combustion chamber to turn into a bomb. In this way, it can not only convert the fuel The combustion rate can be further increased, and the combustion chamber can be made smaller." Lin Bian said without being humble or overbearing.
"A fantasy." The scientist was indeed a person who had dealt with gunpowder and fuel all his life. His temper was equally hot. He just waved his hand indifferently and stopped talking.
Bivariate control is a term that is familiar to scientists present. However, the difficulty in achieving this lies in how to control this dual variable.
So Lin Biao wrote the fourth formula on the blackboard.
The commotion caused by this formula was no less than that of the third formula before, but the objects of the commotion were not the original scientists, but another group of people.
Mechanical Engineers.
"If we treat the entire formula as α and bring it directly into the particle turbulence formula, then we will find that this problem is not actually a problem. We only need to add
Previous ration. "Liang Sicheng said calmly.
"What is this β?" An engineer of the same grade but with an older face stood up from a corner of the auditorium and asked.
"This is a particle flow diverter. Theoretically, as long as there is this flow diverter, it will change the δ just now from a violent lion into a docile kitten. At least it can be controlled within a certain range. It is equivalent to guiding a donkey. Put on the bit and tie the dog on the leash." Lin Biao said.
As soon as this formula came out, the hot-tempered scientist stood up in shock, and the stool under his butt rubbed against the ground, making a harsh sound.
"It still doesn't work. There is no flow guide that can withstand such high temperatures in the combustion chamber without deformation. The most important thing is that the material and welding process of this flow guide, according to the theoretical heating temperature, it is difficult to guarantee its effect. ." The mechanical engineer was stunned for a while, shook his head and said.
"It is indeed difficult to solve this problem with synthetic and manufactured materials. A moment of deflagration and high temperature may turn the entire drainage device into a puddle of useless waste liquid. But have you ever considered natural materials?" Lin Biao Then he spoke.
Before the other party could think about it and ask questions, Lin Biao turned around and wrote today's fifth formula on the blackboard.
Now it was the turn of the scientific researchers in the arsenal to be shocked.
"You want to use carbon!?" A technical vice president of a central enterprise stood up.
"To be precise, it's diamond. To put it another way, diamond will do. The melting point can reach 4,000. It can withstand such high temperatures without any problem." Lin Biao nodded.
"Nonsense, use diamonds to make a flow guide for a disposable missile. Have you ever thought about the cost?" he said incredulously.
"Who said this thing has to be disposable?"
Lin Biao said calmly, but it was earth-shattering!
The noisy discussion echoed inside the auditorium, and even had the tendency to overturn the entire auditorium.
"After a disposable rocket or a single-stage rocket delivers the missile to the target, the entire rocket body will be completely destroyed. What if we make it a two-stage or multi-stage rocket?" Lin Biao said: "Arrival Before setting the target, we detached the rear rocket from the main body, and then made a navigation system to allow the rear rocket to automatically return home, which is equivalent to this part of the rocket only serving as a fighter jet carrying ammunition."
"Then why don't we just use fighter jets?" The vice president was obviously a little moved, but still said with a stiff neck.
At this time, even the Second Artillery Commander sitting in the front row couldn't sit still and turned his head to glance at him like a fool.
Lin Biao finally wrote the last formula of the day on the blackboard.
This formula is written in Chinese, and the reason is very simple. Compared with the existing standard missile production methods, Lin Bian's method can increase the combustion efficiency of the entire rocket by at least 30% on the original basis. The cost can be reduced to half of the previous price!
This formula is for the leaders in the first row, and everyone present can naturally understand it.
The Second Artillery Commander looked shocked, and then hurriedly ordered the adjutant on the side to prepare materials.
Never before in the history of the country, a meeting was held first to sign a confidentiality agreement, and it was born here.
