On August 30, Qin Zhao stood on the flat ground below the Chiyun Peak and watched the Hale Rocket Research Team showcase the final final product.

To put it bluntly, six craftsmen experimented with the best tail angle of the Hale Rockets and showed it to Qin Zhao.

Twelve rockets were arranged on the flat ground directly below the Chiyun Peak, facing four hundred scarecrows one mile away. The scarecrows were tied very roughly, and the distance between them was one step, forming a square array of twenty times twenty times twenty, which was about a square area of ​​thirty meters times thirty meters.

The Ming people took the "one step" to walk the left and right feet, and according to the weights and measures of later generations, it was about one meter five per cent.

The four hundred scarecrows were placed there, making the target area turn yellow and orange, which is easy to distinguish.

Eight launchers who participated in the rocket experiment came up, and each two were responsible for one rocket.

Seeing the launcher holding up the rocket that was finally set with both hands, the six craftsmen wiped the sweat from their heads. They had been doing experiments for more than a month and made more than 500 experimental rockets. Whether it could be achieved depends on today.

The experimentally defined Hell rocket weighs 16 kilograms and four kilograms, of which the shell and stick weighs 4 kilograms and four kilograms, the gunpowder in the propulsion department weighs 2 kilograms and 11 kilograms, the gunpowder in the combat department weighs 6 kilograms and 5 kilograms, and the steel sheet exploded in the combat department is three kilograms. The entire rocket adopts a pointed cylinder shape, which can fly 500 meters in a stable air and hit a circular target with a radius of 15 meters in 500 meters.

If it is a target that is bombing closer and launching at a low angle, the hit accuracy will be higher.

The reason why the shell is so heavy is that the black gunpowder in the Rocket Operations Department will only form a high-pressure explosion under the constraints of the container, otherwise it will only explode and have no lethality.

The power of high-purity black gunpowder is still very great. Qin Zhao later reads related papers. The shock wave power of later high-purity black gunpowder in various distances and equivalents is generally equivalent to about two-fifths of the tnt, or even higher. For example, the shock wave measured at five meters, 0.53 kg of black gunpowder reaches the shock wave pressure level of 0.23 kg of tnt explosive.

The Japanese gunpowder of this era is a little worse, but it is not much different.

The Type 67 grenades in later generations were equipped with only 67 grams, and more than one tael of TNT explosives could bomb an area with a radius of two meters. Qin Zhao's rocket was filled with six kilograms of 5 kilograms of combat units, and its power was naturally extraordinary.

The explosion delay of the rocket is determined by the length of the fuse inside the rocket. Qin Zhao made a screw rotating handle on this fuse, which allows the rocket launcher to adjust the combustion length of the fuse at will before launch to control the explosion time of the rocket. This screw rotating handle looks simple and crude, but is very effective.

The finalized Rockets are called the Qin Rockets, or the Qin Rockets for short.

Now the eight Rockets are holding a type of Qin Rocket.

Everyone walked to a farther place and waited for the launch of these four groups of rocketers.

In each group of two people, one of them was responsible for raising the rocket to aim, and the other was responsible for igniting the fire. The igniter took off the scythe and pressed it hard to ignite the fire seed. Then they took a fire storage rope mixed with gunpowder powder and approached the scythe and ignited the fire storage rope.

Four ignition hands hold fire ropes and wait for commands.

The eight-person upper class leader shouted: "Target, the scarecrow area center one mile away, aim."

Four rocket aiming soldiers lifted the rocket about twenty degrees.

"ignition!"

The four rocket igniters ignited the rocket fuse together, and only a small sound was heard, and the lead ignited the rocket's propulsion. The rocket in the aiming soldier's hand suddenly sprayed a dazzling tail flame into the back, making Qin Zhao and others quickly move away from their sight. The light of the flame was too strong, and staring at it would blind their eyes.

The Rocket made a loud "whoosh" sound, flying towards the scarecrow area, and smashed into the scarecrow target area with a "bang" and "bang".

The Rocket's hard head broke through the early autumn land and drilled into the ground.

All four rockets hit the Scarecrow area.

About two breaths have passed.

"boom!!!!"

"boom!!!!"

"boom!!!!"

"boom!!!!"

The Rockets exploded four huge sparks from the Scarecrow a mile away.

Qin Zhao waved his hand: "Injury check!"

Another team of twenty soldiers ran to the target area and began to check for the scarecrow's damage.

Soon, they came back to report.

"The scarecrow was damaged by thirty-seven, of which seven were shock wave damage, and the overall lodging. The other thirty were damage caused by splash cutting damage from the burst steel sheet. Thirteen of them were severely damaged, and thirteen were moderately damaged and basically lost their combat power. Four of them were lighter and probably still had combat capabilities."

In the first experiment, the Rocket was fully qualified and exceeded the preset standards.

Qin Zhao waved his hand and said, "Try again!"

Soldiers near the Scarecrow area quickly replaced the damaged Scarecrow and replaced the new Scarecrow.

The four rocket aiming soldiers grabbed four rockets and adjusted the length of the fuse through the screw rotation handle, and walked to a place only three hundred meters away from the scarecrow area.

They lifted the rocket slightly and pointed it at the scarecrow in front of them.

The captain roared: "Light!"

The four igniters ignited the fuse together, and only the flames were seen gushing out. Four rockets spewed out huge tail flames and smashed towards the scarecrow area three hundred meters away.

"Swoosh~~~"

Four rockets were accurately shot at the center of the Scarecrow area.

"boom!"

"boom!"

"Boom! Boom!"

The soldier responsible for the inspection results will come back soon to report.

"The scarecrow was damaged forty-three. Seven of them were broken and dispersed by rockets. The other eight were bombed by shock waves and fell down as a whole. The other twenty-eight were cut by burst steel sheets. Only three of the scarecrows were cut by burst steel sheets and were less injured and could still fight."

"Try again!"

The new scarecrow was replaced again, and the eight rocket soldiers walked to a hundred meters away from the scarecrow and took over four rockets again.

This time they almost shot the rocket flat, lifting the rocket a little bit of angle, and almost adjusting the screw rotation handle to the shortest value.

The squad leader shouted: "Light!"

Four rockets shot out like four sharp arrows and plunged into the scarecrow's area.

The Rocket directly pierced several scarecrows on the front and pierced them head-on. Then the Rocket landed in the area behind the scarecrow and made a violent explosion.

Qin Zhao yelled: "Injury check!"

The soldier in charge of the inspection plunged into the scarecrow area and ran back for a long time.

"The scarecrow was damaged forty-seven. Ten of them were hit by rockets head-on and collapsed. The other seven were bombarded and broken by shock waves. Thirty were cut by explosive steel sheets. Five of them were lightly injured and still had combat capabilities."

The five-man team responsible for launching the experimental rocket ran to Qin Zhao in a trot and shouted to Qin Zhao: "Report to Mr. Qianhu, all three rocket experimental demonstrations have been completed. The launcher experiences normal and there is no bad launching condition."

The platoon responsible for counting the scarecrow's injury ran to Qin Zhao and shouted loudly: "Report to Master Qianhu, the rocket's hit accuracy and lethality are better than the expected results in advance, and the overall performance is excellent."

Qin Zhao was very happy to hear the results of the experiment.

He stood up and clapped his palms happily.

From then on, Qin Zhao truly mastered a weapon to defeat the enemy. He could use this weapon to arm his troops, use this new force and various forces in this world to thrive, and no longer the earthless duckweed that is light.

As Qin Zhao thought about it, an excited smile appeared on his face, and the applause became louder and louder.

When the others saw Qin Zhao's appearance, they all followed suit and applauded with Qin Zhao.

There was a burst of applause in the experimental field.
Chapter completed!
