In the military industry that year, the cloud bombs started to wash the ground for monkeys

That is, Zhang Yuan, chief engineer of the rocket launcher research department.

Immediately start to modify the sketches on the drawings on the table.

Lu Xuan nodded slightly. It seems that this Chief Engineer Zhang is not a jealous person, so he continued to speak:

"To make these special-shaped structural parts more aerodynamic, finite element analysis must be done."

"Only through the calculation of infinite approximation by finite elements, can we obtain more accurate data for verification..."

In the military industry system, especially in the military industry system of later generations, finite element analysis is essential.

In the later generations when computers are popular, there are professional graphics software to carry out such complex calculations.

In this era, calculations in this area can only be done manually, and the amount of calculation is a bit large.

"You also know finite element analysis?"

Mr. Zhang couldn't believe that the young man in front of him had studied finite element analysis.

In fact, finite element analysis has been produced and applied a long time ago.

For example, use a polygon to approximate a circle to find the circumference of the circle.

But the real large-scale application came after the eight 90s computers were used.

Therefore, when they designed and researched rocket launchers, they never thought of using finite element analysis.

"Finite element analysis is the use of mathematical approximation methods to simulate real physical systems."

"Using the unit can know a finite number of unknowns, approaching a real system with infinite unknowns..."

Now that it has been brought up, Lu Xuan simply explained his understanding of the finite element analysis theory.

"Don't be so esoteric, give me an example."

Mr. Zhang was shocked in his heart, but said without much expression on his face.

Lu Xuan nodded lightly, and continued: "For example, the design of airplane wings."

"It is to use countless same curves to treat the whole aircraft wing as a straight line."

"On this curve, the more points you take, the closer the final result is to the designed curve."

"In the process of processing, the more precise the points are, the more aerodynamic the finished aircraft wing will be."

"It makes the aircraft have better flight performance, and the same is true for the improvement of the rocket tail you designed."

"I see." Mr. Zhang nodded thoughtfully.

The other experts present also had an expression of enlightenment.

Whether it is researching rockets, missiles, or even aircraft, this method is very useful.

In the process of processing, processing with finite element analysis method can also guarantee the maximum processing quality.

Wind Tunnel Laboratory.

Today is the day for wind tunnel testing of the newly produced rockets.

Since Lu Xuan suggested changing the layout of the rocket fins to be more aerodynamic.

Under the leadership of Chief Engineer Zhang of the Rocket Research Department, the rocket bombs they designed and developed were redesigned.

After several months of hard work day and night, the trial production of the latest fire bomb was finally completed and the first wind tunnel test was carried out.

The leaders of the entire 618 base, including Lu Xuan, the youngest weapon designer, were invited here.

"Mr. Zhang, our experimental tasks are heavy. Rockets are not missiles, and their range is not very far. They are all based on quantity. Is it necessary to do wind tunnel experiments?"

Yang Changgen, director of the base, was very dissatisfied with Mr. Zhang's actions.

This wind tunnel laboratory is specially set up for the missile research department.

The missile design office has yet to get their missiles out for wind tunnel testing.

You, a rocket launcher, want to conduct a wind tunnel test of the rocket launcher, you are simply playing the piano indiscriminately.

In his cognition, the rocket launcher should be like Katyusha.

Dozens of rocket launchers were shot out for fire coverage.

Not much precision is needed at all.

In fact, not only Yang Changgen thinks this way, but also all the experts in the Rocket Launcher Design Office think so.

But last time Lu Xuan reminded them that the fire bullet also needs to be aerodynamic, and it also needs precision strikes.

So they overthrew the previously designed rocket, changed the tail layout, and re-produced this rocket.

When another leader of the base, Director Wang Mingyi, who was in charge of weapon research and development, saw the rocket.

The corner of his mouth also twitched: "Old Zhang, why does the more I look at it, the more this rocket looks like a missile?"

Regardless of whether they understand technology or not, they all know the shape of rockets and missiles very clearly.

In particular, the two sets of tail fins that stabilize the flight attitude only appear on missiles.

Moreover, the caliber of this rocket is a bit large, much larger than that of the Katyusha rocket.

"Director Wang, you have to ask Comrade Xiao Lu about this."

"We re-produced it according to his design concept."

"Even the engine of the rocket has been redesigned to increase the thrust."

Mr. Zhang looked at Lu Xuan with a smile and said, he agreed with Lu Xuan.

Yang Changgen, Wang Mingyi and the others immediately looked at Lu Xuan with incredulous expressions on their faces.

Lu Xuan was one of the weapon designers they recruited, although everyone knew that Lu Xuan was very talented.

But after all, Lu Xuan is just a fresh graduate, and he actually guides these old experts in the research and 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.

But at the beginning, he just suggested that the experts in the Rocket Launcher Design Office change the design of the front and rear fins to make it more aerodynamic.

I didn't know that these experts were so crazy that they made the rockets look like missiles, at least the appearance was like this.

Lu Xuan had no choice but to explain: "This shape design will greatly reduce the air resistance, making the rocket's flying attitude more stable and its range longer."

"There is no problem with the short range of the rocket launcher. If the range is long, if the air has too much influence on the flight process, it is very likely that the impact point will be shifted by several kilometers, or even farther..."

Aerodynamics is critical to the impact of flying objects, which is why missiles must be tested in wind tunnels.

When designing any aircraft, this problem needs to be considered, and then continuously improved during the trial production process.

"Well, whether it's rockets, or missiles, or whatever, as long as you can come up with a good product."

Yang Changgen doesn't understand professional things, he only wants the 618 base to develop more military products, other things are not important.

003 A plan to enhance the power of rockets

It often takes thousands of hours or even longer for missiles to conduct simulated flight experiments in wind tunnels.

The high-speed camera in the wind tunnel can capture all aspects of the flight trajectory of high-speed flying objects.

Many large missiles have to carry out wind tunnel experiments even from the finalization of the design to the decommissioning of this model.

During the wind tunnel experiment, the product will be improved, resulting in some improved models.

Of course, the requirements for rockets are not as high as those for strategic missiles and space rockets.

There is no need for a series of experimental tests from low speed, medium speed to high speed.

Therefore, this rocket was tested at high speed from the beginning.

"How many?"

After the high-speed experiment was carried out for a period of time, Mr. Zhang asked.

"Muzzle velocity 163 meters per second."

"Normal flight speed breaks through the speed of sound."

"After flying for a certain distance, with the consumption of fuel, the reduction of weight, and the effect of inertia, a higher speed can be obtained."

"According to the analysis of such experimental results, the effective range of our rocket may reach 80 kilometers, or even higher..."

Hearing these statistics, everyone present was so shocked that their jaws almost dropped.

With a range of 80 kilometers, the flight speed exceeds the speed of sound.

It takes two to three minutes to reach the designated strike target area.

Are you sure it's a shell, not a missile?

Lu Xuan was satisfied with the various data of this rocket.

Although it cannot be compared with the rocket launchers of later generations with a "range of 1700 kilometers and an error of [-] kilometers".

But what year is this?It is already terrifying to have such a range and flight speed.

Such a rocket launcher, not to mention hitting ground targets, is also good for air defense.

Especially when used to fight against helicopters, there is no problem at all.

Later, with the addition of Jia Yiming, various high-tech materials continued to appear.

The research and improvement of rocket engines will only get faster development.

At that time, the rocket launcher will only have a longer range and a higher speed.

"Continue to carry out the wind tunnel experiment of the rocket and record the data completely."

Mr. Zhang gave an order, turned and left the wind tunnel laboratory, followed by all the experts.

They knew that the wind tunnel experiment only proved that the shape and engine design of the rocket met the standards.

With the range increased by two-thirds, it would be a bit reconciled if the rockets were only as powerful as before.

When he came to the meeting room, Chief Engineer Zhang asked Lu Xuan kindly: "By the way, Comrade Xiao Lu, do you know if there is any other way to increase the power of the warhead besides loading more explosives?"

After the wind tunnel experiment of rockets, it is enough to show that Lu Xuan's talent in rocket design is strong.

Therefore, when improving the power of the rocket launcher warhead, Chief Engineer Zhang first sought Lu Xuan's opinion.

Lu Xuan chuckled: "If the power is maximized, it is natural to install nuclear warheads on it."

"Damn it, can you make mushroom bombs casually?" Yang Changgen was impatient.

Can a rocket launcher equipped with a nuclear warhead be used on the battlefield?

Maoxiong has developed a lot of tactical nuclear missiles.

Eagle Sauce is also under development.

Rabbit didn't give up either.

But who dares to use it on the battlefield?

A weapon that cannot be used on the battlefield is meaningless.

Of course Lu Xuan was just joking, to liven up the atmosphere.

In fact, he already had a plan in mind to increase the power of the rocket.

That is the cloud bomb developed by various countries after entering the 21st century.

The cloud bomb is called the most powerful conventional weapon under the mushroom bomb.

The production technology of this thing is simple and the cost is low. It is called "the poor man's nuclear bomb".

I just don't know what the effect will be when this thing is combined with the rocket launcher.

Isn't the monkey clamoring that they are the third military power in the world?

Didn't they invade the rabbits with the support of the furry bears?

Then use this thing to fix them once.

Let's see if they dare to be so arrogant.

Dare to grab the island with the rabbit.

"I heard that Mao Xiong and Ying Jiang are researching an air bomb, and the warhead is loaded with concentrated fuel."
