1959: Carrying the achievement system, she rolled

As for fuel, she initially considered using a double-base propellant, whose main components were nitrocellulose and nitroglycerin.

Its advantages are uniform texture and structure, good reproducibility, less smoke, low explosion temperature, etc., and the raw materials are widely available and inexpensive, which means low cost.

This type of propellant is used in the solid rocket engine of the Katyusha rocket launcher.

Unfortunately, the main purpose of a rocket launcher is to be lightweight, which limits the structure of the engine and prevents it from being too complicated.

After testing, it was found that the range of the rocket launcher using double-base propellant was only more than 100 meters, which is even worse than the range of the Type 51 rocket launcher.

In other words, using double-base propellant on a rocket launcher would not achieve the effect she wanted.

So she made improvements to the double-base propellant, adding oxidizer and aluminum powder, and replacing the adhesive with polyurethane adhesive.

"Shall we do a test firing?" Du Yimeng said eagerly. She really wanted to carry the gun on her shoulder and fire it.

During the previous test firing, she had just put the rocket launcher on her shoulder when it was confiscated. The reason was that the rocket launcher was not yet perfected and was too dangerous, so she could not take the risk.

As a result, no other dangerous problems occurred except that the range did not achieve the expected effect.

So her restless heart began to stir again.

"What are you waiting for? Let's go..." Wan Ping was a man of action. He picked up a box of rockets and rushed out.

During the last test firing, I watched the operator carry the rocket launcher on his shoulder and fire a rocket. It was a magnificent sight.

So majestic...

How many times have I dreamt of that scene in the middle of the night?

He has to have sex today no matter what. Who doesn't want to try?

Du Yimeng was not to be outdone. He picked up a rocket launcher and ran after Wan Ping.

Because she and Wan Ping have the same little idea, everyone has a dream of being a weapon, regardless of gender.

"Wait..." Qin Chulong's hand was still stretched in the air. He wanted to say that the test launch required a professional operator to control it.

What if the shot misses?

It would draw the roar of Director Liu from the logistics department...

Wan Ping and Du Yimeng rushed to the test site and saw that there was no one there. They looked at each other and saw excitement in each other's eyes.

"I'll go first. The remaining rockets are all yours." Du Yimeng saw Wan Ping was about to speak, so she spoke first.

She wanted to take his path and leave him with nowhere to go.

"That's what you said." Wan Ping, who was originally unhappy, smiled happily the next second.

There were three rockets in a box, and Du Yimeng used them all...ah, it was just a test launch, he could have tested it twice.

He made a fortune...

However, the two did not waste rockets blindly, and took the concrete obstacle 300 meters away as the target.

Now the institute's test targets are no longer steel plates, but concrete obstacles with a thickness of one meter.

As for the reason, of course it is to save money.

"Hurry up and pull the trigger." Wan Ping was so anxious when he saw Du Yimeng aiming for a long time but not firing.

But he didn't dare to get close, for he was worried that Du Yimeng, whose aim was not good, would take him as a target.

"What if the attack hits the opposite wall?" Du Yimeng asked worriedly.

Her target was a concrete obstacle 300 meters away. What if she missed?

You have to know that the propellant in the rocket launcher now has been added by her, and the thrust is much greater than the previous double-base propellant, so the range is definitely longer than before.

When she saw the wall, she subconsciously thought of Director Liu with a bad temper.

Once when the tank was being tested, the operator accidentally made a mistake and blew a big hole in the wall. As a result, Director Liu scolded him severely.

If Director Liu, who was furious, scolded her like this, she would become autistic.

It’s no wonder that Director Liu is so irritable, because there are frequent mistakes, which means that the wall here is often blown down.

She remembered that it was quite busy here in the past two days, but she didn't pay attention to what they were busy with.

The operator cannot be blamed. It is called a test launch because it is normal to make mistakes frequently.

"The wall is thousands of meters away from here, how could it be attacked? Don't worry, if anything goes wrong, it will be my fault. I will write the self-criticism and you can deduct my salary if I have to pay compensation. Anyway, I have more money than I can spend." Wan Ping said righteously, he was not short of money.

He had never been short of money before, and he became even richer after he reunited with his biological father. Now he just needed someone to spend money.

"Okay, I feel relieved with your words." After saying this, Du Yimeng aimed at the target and quickly pulled the trigger, all the actions were done in one go.

When the trigger is pulled, the trigger mechanism releases the firing pin, which in turn strikes the primer, causing the primer to produce a spark and finally ignite the propellant in the engine, that is, the fuel.

The propellant converts chemical energy into thermal energy in a short period of time, producing high-temperature and high-pressure combustion products.

The combustion products flow into the nozzle, where they expand and accelerate, and then are converted from thermal energy into kinetic energy, and finally are discharged from the nozzle at high speed, thereby generating thrust.

And this thrust is the power required to launch the rocket.

Qin Chulong and Wan Ping also installed a stabilizer on the tail of the rocket. During the flight of the rocket, the blades of the tail stabilizer will unfold.

It can ensure the stability of the rocket and thus improve shooting accuracy.

Wan Ping, standing by, watched the rocket whizz out and head towards the target obstacle.

His heart was filled with excitement, as it would soon be his turn.

Unexpectedly, Du Yimeng's aim was very accurate, but what happened next made him want to slap himself.

Because just when he thought he was going to hit the target obstacle, the rocket passed by the target obstacle and flew backwards.

Du Yimeng, who had been so excited just now, was now confused. She had obviously aimed very accurately!

However, thinking about what Wan Ping said, the wall was still thousands of meters away from here, she felt that the maximum range of this rocket was only about 900 meters.

There's still a 100-meter gap between us, but I'm not afraid...

"boom……"

The wall in the distance collapsed with a loud bang, and all the relief on Du Yimeng's face disappeared.

It's over...

She seemed to hear Director Liu roaring...

"What's going on?" Wan Ping looked at the distance in confusion, where thick smoke was billowing.

"The wall has collapsed!" Du Yimeng reacted quickly. While speaking, he quickly stuffed the rocket launcher in his hand into Wan Ping's hand.

He had said before that if anything happened, he would write a self-criticism, and his salary would be deducted to compensate him. It had nothing to do with her.

At this moment, Wan Ping's face was filled with confusion and bewilderment.

He looked at the rocket launcher in his hand, then glanced at Du Yimeng in disbelief. Finally, he set his sights on the place in the distance where thick smoke was still billowing.

The only thing that came to his mind was that the range was so great, it actually hit the wall...

At the same time, Political Commissar Yang and Director Song, who were running towards the test site, did not notice who the culprit was, but only saw the wall collapsing in the distance.
