When he came to the machine tool and stood still, Li Xiang asked people to find some materials for trial production of rocket artillery, a vise, and a pair of iron scissors. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 infoHe's going to use this machine to make a rocket.

If there is no super 3D printer, Li Xiang will definitely not be able to operate the machine tool, let alone make rockets, but with the information provided by the super 3D printer and hologram operation images, Li Xiang is equivalent to drawing a scoop according to the gourd!

The metal materials used by the artillery factory to make rockets quickly turned into parts in Li Xiang's hands, which was as pleasing to the eye as magic! This small machine has a complete processing capacity, whether it is turning, cutting, drilling, etc.

The shell of the rocket engine, which is eight centimeters in diameter and thirty centimeters in length, is made of iron sheets bent into a cylindrical shape and then spliced together.

The turbine, combustion chamber, and nozzle are also made of iron sheet cutting and twisting.

It only took half an hour to make a simple rocket engine! Everyone present was impressed by Li Xiang's superb machining skills, which was simply watching an art performance!

Those skilled craftsmen were also shocked at this time, and they couldn't help but feel admiration from the bottom of their hearts! Their ambassador is so powerful!

Gently stretched his arms and waist and abdomen, Li Xiang felt a little better, the hour's labor just now seemed simple, but in fact it was painstaking and laborious! Fortunately, with the assistance of a super 3D printer, nothing went wrong, otherwise it would be a shame.

Li Xiang looked at the rocket engine in his hand with satisfaction, and said with a smile: "Look, this is the power of rocket artillery, it is called a jet engine, the fuel is burned in the combustion chamber of this rocket engine, and then expands to produce high-pressure gas, which is sprayed outward through the nozzle to produce a reverse thrust and push the rocket to fly out." ”

Zhang Shijie took a step forward, picked up the rocket engine in Li Xiang's hand, and observed it several times before raising his head, looking at Li Xiang with admiration and saying, "My lord, your engine is really ingenious!" Terrific! You don't have this design, this craftsmanship is not to say! I, Zhang Shijie, am completely convinced! In the future, if you have anything to do with me, even if you go up and down the sea of fire, I, Zhang Shijie, will not even frown!"

Li Xiang gently patted Zhang Shijie's shoulder and smiled gently: "It's nothing, in fact, the reason is very simple!" I'm sure you can figure it out at a glance. I am very optimistic about you, do a good job, in the future, we must have an artillery production institute, and it depends on you! ”

Next, Li Xiang used a machine tool to make the body of the rocket, and loaded the propelled gunpowder into the body of the bomb, of course, the warhead was not equipped with explosives, after all, it was only used for testing.

The craftsmen were shocked, because they made a lot of rocket samples according to Li Xiang's drawings, but they always failed.

After making a test sample of a rocket, Li Xiang said: "Okay, the sample of this rocket has been made, and everyone wants me to go to the test site with me to conduct a launch test to see if this rocket can be successful!" ”

This rocket is about 1.5 meters long, 10 centimeters in diameter, and weighs about 20 catties, similar to the 90-millimeter air-launched rockets of later generations.

A craftsman carried a rocket, and everyone made their way to the test site.

Li Xiang mounted the rocket on a slide rail, and the rocket pointed at the sky at an angle of 70 degrees, so that it was ready for launch.

At this time, Li Xiang said to everyone: "Everyone stand farther away, at least keep a distance of fifty steps, this rocket has a lot of gunpowder, in case the test fails, if there is an explosion, it will hurt ourselves." ”

After speaking, Li Xiang said to the craftsman who lit the fire: "After lighting the fire, immediately retreat to the back, understand?" ”

Although the craftsman was very excited, he became the first person to release the rocket, but he also understood that this rocket was not a joke, and if he didn't retreat quickly, if it exploded, his life would be over. So the craftsman nodded and said, "My lord, the little one understands!" ”

Li Xiang nodded, retreated fifty steps away, and then ordered: "Ignite!" ”

I saw that the fuse that the craftsman had carefully exposed the rocket had missed, and with a puff of green smoke, the fuse burned and quickly shortened, and the craftsman quickly ran back into the crowd.

As the fuse was burned, a blazing flame erupted from the tail of the rocket, and at the same time, the green smoke also rose into the air, and the rocket shot into the sky in the direction of the slide rail, and the flame at the tail still burned for several seconds before extinguishing, looking like a comet in the daytime.

Everyone stared intently at the rocket's trajectory, first looking up, then lowering until it hit the ground and plunged deep into the dirt of the test site.

Zhang Shijie said excitedly: "Big, my lord, this range is too far!" No less than 500 paces away! Compared to the range of the Divine Arm Bow, it is at least twice as farther, which is too powerful! ”

Li Xiang also visually inspected it, this range is about seven or eight hundred meters, isn't it exactly five hundred steps away? However, this is still a lot worse than Li Xiang's target range, compared with the Type 05 rocket of later generations, this rocket is far worse, of course, the propellant of this rocket, and the material must be far inferior to later generations, the kind of individual rocket in later generations, the body and engine weigh only two kilograms, the solid launch fuel is about 1.5 kilograms, the warhead is about 1.5 kilograms, the total weight is about five kilograms, the cruising speed is 300 m/s, and the maximum range is about 2,500 meters.

The rocket made by Li Xiang is twice as heavy as the individual rocket, but the range is only about one-third of the latter, which is caused by the gap in materials and processing technology.

But it's not bad, there's no shame, the first test of the rocket was successful! Li Xiang also felt very happy, and now the officials and craftsmen of the artillery manufacturing institute have seen hope, as long as they follow their own design drawings and learn how to operate the machine tool, they can make rocket artillery in batches.

Li Xiang also believes that the craftsmen of the Great Song Dynasty are also very smart, and it should not take too long to learn to operate the machine tool. Even, Li Xiang felt that the craftsmen might come up with some new inventions after mastering modern mechanical knowledge, and it was not necessary to improve the design of rocket artillery.

Several craftsmen hurriedly ran to the place where the rocket landed and measured its range, and sure enough, the results of the accurate measurement showed that the first rocket of the Great Song Dynasty reached a range of 520 steps during the test launch, which was already very remarkable, and both the officials and the craftsmen were excited.
