Yang Fan raised his wrist and looked at his watch. It was already dawn at 5:10 in the morning.
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 messenger immediately raised his signal gun and pulled the trigger toward the sky.
Chirp! There was a drawn-out sound and a flare went up.
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 beautiful country during the Vietnam War.
This signal gun has a caliber of 40mm and is in the shape of a short rifle with a butt. Use mid-fold filling. Open it from the middle, bend the gun body and butt in the middle, expose the gun chamber, and then load the breech.
In addition to the smoke components, aluminum powder and magnesium strips are also added to the flare. It will burn violently after liftoff. Emit a violent bright light.
As the flare takes off. The infantry at the front of the team immediately set up their shields, and the others took cover behind their shields. Prevent enemy attacks.
The three infantry regiments were arranged in horizontal lines according to the sentry unit. There are one hundred people in each sentry team, forming a square formation that is twenty people long and five people thick. Behind them, separated by a distance of thirty meters, were fifty rail-type rocket launchers.
Each transmitter is connected to ten launch slots side by side, and the angle has been adjusted with a bracket. Rockets pointed at the sky.
These rocket artillerymen of the Ming Dynasty belong to Yang Fan's servants. Yang Fan would not hand over such an important weapon to the imperial army.
But Yang Fan didn't hide it from them. If the emperor wants to buy it in the future, Yang Fan can also sell it.
After all, he already has a new generation of rocket launchers 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 eliminated 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 fire stick from his arms, blew it brightly, and lit it near the fuse.
The fuse crackled and burned rapidly. Three seconds later, 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, whoosh whoosh! Rockets were launched one after another, all in sequence. The speed is so fast that it is 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 pack needs to be reloaded before firing.
The propellant pack is divided into ten, each representing a range of 200 meters. Load as many as you need. The drug package is filled into the rear pipe of the rocket.
More subtle fine-tuning is achieved by adjusting the angle of the transmitter. Generally, when the propellant package is the same, the 45-degree angle has the longest range.
Before launching, these artillery technical officers also have to measure the wind direction and speed.
There is no way, the technology of this era is too poor, causing the spread area to be much larger than that of later generations. Wind speed and direction must be calculated. Adjust in advance. Otherwise, who knows where it will fly to. It’s not just once or twice that forest fires were caused during test firings.
The barren mountain at the test site was burned to the ground. Because no one dares to save this fire. You can only watch it burn out until it is completely extinguished and there are no more combustibles left.
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 person keeps coughing.
Yang Fan frowned. Although he was on the hillside, the smoke below was hot and would steam upward.
He took out the mask from his pocket and put it on. When others saw that the master was wearing a mask, they also took out the pure cotton masks made by the Xincheng Quilt Factory and put them on.
The smell of gunpowder smoke was very choking, but even though I put on a mask, I could breathe better. But Yang Fan felt uncomfortable in his eyes. He was thinking about whether it was time to put smokeless gunpowder on the agenda.
The artillerymen rushed to the carriage behind and unloaded new rockets from it. Ready to reload.
This kind of rocket is quite heavy and requires several people to carry and load it.
When the artillerymen were selected, strong and tall men were selected, which was the same as the selection criteria for the navy. Without a good physique, the average person would not be able to do this kind of work, and would be exhausted within 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. Terrifying and poignant. It's 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 listen to the inheritance of 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 swaggered across the river 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 they should have a fox tail tied behind their buns. To show that they are as timid as foxes.
What's so scary about an army that doesn't even dare to leave the city?
So after he arrived at the place to set up camp, he immediately relaxed. Apart from arranging some cavalry along the Yellow River, there was not much precaution.
They desperately need rest. Because they came 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, had a big meal, and then slept soundly. The sound of snoring was loud.
Suli Tang 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.
Although he was still hungover and had a severe headache. He still heard the whistling sound in the air.
He sat up immediately. Trying to shake his head to wake up his hangover.
