In his previous life, Lu Xuan had worked hard for the military industry of the rabbit family all his life.
Although he couldn't cover everything, he still had a good understanding of the rockets of this era.
Be it rockets or missiles, they all had to be like all kinds of aircraft, which had to be in accordance with the laws of aero.
However, Lu Xuan was still too young.
Even though they believed that geniuses existed in this world.
However, Lu Xuan was just a fresh graduate of the University of Industry, Peasants and Soldiers.
Now you're telling them that you know a thing or two about rocket launchers?
The design of rockets involved many aspects.
Even if you start learning all kinds of knowledge from the womb.
It was impossible to be comprehensive and proficient.
However, as Lu Xuan continued to explain in depth, the rocket launcher engineers present could not help but be fascinated.
Lu Xuan began to suggest some common rocket designs in the future.""Change these four tail fins to four at the front and back.”
"The front four fins are about one-third of the way to rectify the air resistance in front of the missile for the first time.”
" There are still four wings at the rear, arranged at 45 degrees or on the same axis as the wings at the front. It's obviously much better…"
Upon hearing Lu Xuan's introduction, the engineer from earlier was also a very familiar person.
He was the chief engineer of the Rocket Launcher Research Center, Zhang Yuan.
He immediately began to modify the sketch on the table.
Lu Xuan nodded slightly. It seemed that Chief Engineer Zhang was not a jealous person. He continued,"
"If we want these deformed structures to be more in line with the airflow, we must do a finite-element analysis.”
" Only through the calculation of the finite-element method can we obtain more accurate data for verification…"
In the military industry, especially in the future, the use of finite-element analysis was essential.
In the later generations of computers, there were professional graphics software to perform such complicated calculations.
In this era, calculations in this area could only be done manually, and the amount of calculation was a little too large.
You know about the finite-element analysis?"
Chief Engineer Zhang found it hard to believe that the young man in front of him had studied the finite-element analysis.
The finite-element analysis had actually been produced and applied a long time ago.
For example, the circumference of a circle could be obtained by using a hexagon to approximate the circle.
However, the real large-scale application was after the use of computers in the 1980s and 1990s.
Therefore, when they designed and researched the rocket launcher, they never thought of using the finite-element analysis.
"The finite-element analysis is to use mathematical methods to simulate real physical systems.”
" By using the unit, we can know a limited number of unknowns and approach a real system with infinite unknowns…"
Since he had already brought it up, Lu Xuan might as well explain his understanding of the theory of finite-element analysis.
"Don't be so profound. Give me an example.”
Chief Engineer Zhang was shocked, but his face was expressionless.
Lu Xuan nodded gently and continued,"" For example, the design of airplane wings."
"It is to use countless identical curves to view the entire plane wing as a straight line.”
"On this curve, the more points you take, the closer the final result will be to the designed curve.”
"In the process of processing, the more precise the points are, the more the aircraft wings will be in line with the aircraft's dynamics.”
"This will allow the aircraft to have better flight performance. The same principle applies to the improvements I made to the rocket tail that you designed.”
"I see." Chief Engineer Zhang pondered and nodded.
The other experts present also looked enlightened.
Whether it was researching rocket launchers, missiles, or even airplanes, this method was very useful.
In the process of processing, using the finite-element analysis method to process could also guarantee the processing quality to the greatest extent.
In the wind tunnel laboratory.
Today was the day of the wind tunnel test for the newly developed rocket.
Ever since Lu Xuan suggested changing the layout of the rocket's wings to make them more in line with the design of the aircraft's aero.
Under the leadership of Chief Engineer Zhang of the Rocket Cannon Research Institute, they had re-designed the rocket they had designed.
After several months of hard work, the latest Fire-Jane Bullet was finally completed and was tested in the wind tunnel for the first time.
All the leaders of Base 618, including Lu Xuan, the youngest weapon designer, were invited over.
"Chief Engineer Zhang, our experimental mission is heavy. Rockets are not missiles, and their range is not very long. We win with quantity. Is there a need to do wind tunnel experiments?”
The director of the base, Yang Changgen, was very dissatisfied with Chief Engineer Zhang's actions.
This wind tunnel laboratory was specially set up for the Missile Research Division.
The missile design department had not produced their missile for wind tunnel testing yet.
You, a rocket launcher, want to conduct a wind tunnel test on a rocket launcher? That's nonsense.
In his understanding, rocket launchers should be like Katyusha.
Dozens of rocket launchers were fired to cover the area.
It didn't require much precision at all.
In fact, not only did Yang Changgen think so, but all the experts in the Rocket Launcher Design Office also thought so.
However, Lu Xuan had reminded them last time that the fire-chip bullets also needed to be in line with the airflow and also needed to be accurate.
Therefore, they had to redo the previously designed rocket, change the tail layout, and re-produce this rocket.
The other leader of the base, Division Chief Wang Mingyi, who was in charge of weapons research and development, saw the rocket.
"Old Zhang, why does this rocket look more and more like a missile?"”
Regardless of whether they understood technology or not, they knew the shape of rockets and missiles very well.
Especially the two sets of tail fins that stabilized the flight attitude. They would only appear on missiles.
The caliber of this rocket was a little bigger than the Katyusha rocket.
"Chief Wang, you have to ask Comrade Little Lu about this.”
"We re-produced it according to his design concept.”
"Even the rocket engine has been re-designed to increase the thrust.”
Zhang Gongzong looked at Lu Xuan with a smile and said, as if he agreed with Lu Xuan.
Yang Changgen, Wang Mingyi, and the others immediately looked at Lu Xuan in disbelief.
Lu Xuan was one of the weapon designers they had recruited, even though everyone knew that he was very talented.
However, Lu Xuan was just a fresh graduate after all. How could he guide these old experts in the development of rocket launchers?
The corner of Lu Xuan's mouth twitched. In fact, he could tell that the rocket in front of him was indeed more like a missile.
However, he had only suggested that the rocket launcher design experts change the front and rear wing design to make it more streamlined.
Who would have thought that these experts would be so crazy as to make the rockets look exactly like missiles, at least in appearance.
Lu Xuan had no choice but to explain." Such a design will greatly reduce the air resistance, making the rocket's flight attitude more stable and its range longer.”
" It's not a problem for the rocket launcher to have a short range, but if it has a long range, if the air affects the flight process too much, it's very likely that the impact point will deviate by several kilometers or even further…"
The effect of the air force on the flying object was very important, which was why the missile had to be tested in the wind tunnel.
This was a problem that had to be considered during the design of any aircraft, and it would be continuously improved during the trial production process.
"Alright, it doesn't matter if it's a rocket, missile, or anything else, as long as you can come up with a good product.”
Yang Changgen didn't know much about the technical stuff. He just wanted Base 618 to develop more military products. Nothing else mattered.
