Yang Fan raised his wrist and looked at his watch. At 5:10 in the morning, it was already starting to get light.
Although the sun has not come out yet, the sky and the earth are so gray that each other can clearly see each other's faces.
"Let's start, shoot a red flare." Yang Fan said.
The orderly soldier immediately raised his signal gun and pointed it at the sky and pulled the trigger.
Chirp! There was a prolonged sound and a signal flare was raised.
In the early morning sky, the signal flare was particularly conspicuous.
In view of the performance problems of gunpowder in this era, the flare gun was made particularly large. It is somewhat similar to the M79 grenade launcher used by the United States during the Vietnam War.
This type of flare gun has a caliber of 40mm and adopts the shape of a short rifle with a butt. It adopts a folding type loading method. It is opened from the middle, the gun body and the butt are bent and opened in the middle to expose the gun bore, and then the breech is loaded.
In addition to the smoke components, the flare also contains aluminum powder and magnesium strips. It will burn violently after being lifted into the air and emit a violent bright light.
As the signal flare took off, the infantrymen at the front of the team immediately set up their shields, and the others took cover behind the shields to prevent enemy attacks.
The three infantry regiments were arranged in horizontal lines according to sentries. Each sentry had one hundred people, forming a square formation of twenty people long and five people thick. Behind them, separated by a distance of thirty meters, were distributed
Fifty rail-mounted rocket launchers.
Each launcher is connected to ten launch slots side by side. At this time, the angle has been adjusted with brackets. Each rocket is facing the sky.
These rocket artillerymen of the Ming Dynasty belonged to Yang Fan's servants. Yang Fan would not hand over such important weapons to the imperial army.
But Yang Fan didn't hide it from them. If the emperor wanted to buy it in the future, Yang Fan could also sell it.
After all, he already has a new generation rocket launcher with a range of four kilometers and twelve tube launchers. That can be said to be a real rocket launcher.
The four-meter-long bamboo pole was canceled and replaced with four deflected nozzles and self-rotation stabilization technology with spray angle.
As the signal flare went up, rocket launcher commander Tang Erhu shouted, "Fire!"
Immediately, the launcher took out the tinder box from his pocket, blew it brightly, and brought it to the fuse to light it.
The fuse burned rapidly and crackled. After three seconds, the fuse burned to the end and the flame entered the projectile body.
A second later, there was a bang, and intense flames erupted from the tail of the rocket.
The rocket flew high into the sky with a whoosh.
Then, swish, swish! Rockets were launched one after another, all in sequence. The speed was so fast that it was jaw-dropping.
The maximum range of the current Kangolev rocket with bamboo pole stabilization is two kilometers. If the range needs to be adjusted, the cylindrical propellant package needs to be reloaded before launch.
The propellant packets are divided into ten, each representing a range of 200 meters. Fill as many as you need. The propellant packets are filled into the back pipe of the rocket.
More subtle fine-tuning is achieved by adjusting the angle of the launcher. Generally, when the propellant package is the same, the 45-degree angle has the longest range.
Before launching, these artillery technical officers also measure the wind direction and speed.
There is no way, the technology of this era is too poor, causing the dispersion area to be much larger than that of later generations. The wind speed and direction must be calculated and adjusted in advance. Otherwise, the devil knows where it will fly. The forest fires caused during the test firing are not two at once.
times.
The barren mountain at the test site was burned to the ground. Because no one dared to save the fire, we could only watch it burn cleanly and there would be no combustibles left until it naturally went out.
Five hundred rockets, chirp, chirp, chirp! A series of launches took less than ten seconds.
For a time, the entire launch site was shrouded in smoke. The choking people kept coughing.
Yang Fan frowned. Although he was on the hillside, the smoke below was hot and would steam upward.
He took out a mask from his arms and put it on. Seeing that the master was wearing a mask, others also took out pure cotton masks made by the Xincheng Quilt Factory and put them on.
The smell of gunpowder smoke was very choking. Even though he wore a mask and could breathe better, Yang Fan felt his eyes were uncomfortable. He was wondering if it was time to put smokeless gunpowder on the agenda.
The artillerymen rushed to the carriage behind them and unloaded new rockets one after another from it, preparing to reload.
This kind of rocket is quite heavy and requires several people to carry and load it.
When the artillerymen were selected, they were all big, strong, and tall men, which were the same as the standards for selecting the navy. Without a good physique, ordinary people would not be able to do this job, and they would be exhausted after a few strokes.
After the second batch of rockets was installed, the smoke was completely blown away by the wind.
At this time, Yang Fan saw that the first batch of rockets had landed.
When the rocket took off, the whistle above made a sharp whistling sound. It was terrifying and shrill, like ghosts crying and gods howling.
The Yarkand army who was sleeping immediately woke up.
They have been in southern Xinjiang for too long, and they are mixed descendants of Mongolians and various ethnic groups in southern Xinjiang. Many of the fine traditions of the Mongols have been lost. They have no place to pass on the technology.
They never dreamed that they would be attacked that night as soon as they arrived across the Yellow River.
When they crossed the Yellow River, it took them ten days. While watching the cowards in Ningxia Town, they crossed the river openly and openly.
From the beginning to the end, those cowards did not leave the city. They did nothing but close the city gate tightly.
This is the first time for the Yarkand people to deal with the officers and soldiers of the Ming Dynasty since the founding of the People's Republic of China.
The first impression is very important and often determines many subsequent actions.
They laughed crazily at these cowards, these eggless bastards. They laughed and cursed that a fox's tail should be tied behind their buns to show that they were as timid as foxes.
What's so scary about an army that doesn't even dare to leave the city?
So when he arrived at the place to set up camp, he immediately relaxed. Apart from arranging some rangers along the Yellow River, he didn't take too many precautions.
They urgently need to rest because they came here through the Alxa Desert.
They passed through the Badain Jaran Desert, the Gurbantunggut Desert, and the Tengger Desert in succession. Although they repaired at the two oases of Juyanhai City and Heishui City on the way, they were exhausted when they arrived here.
So they first killed cattle and sheep and had a big meal, and then slept soundly. Their snoring was loud.
Su Litang is a fat man in his thirties. Last night, he took a bath, watched the singing and dancing of girls brought by the army, and got very drunk.
Even though he was still hungover and had a severe headache, he still heard a whistling sound in the air.
He sat up immediately and tried to shake his head to wake up his hangover.
