After Ye Liangchou, the Firearms Research Institute, returned with Fang Nan's mission, he immediately dispatched personnel to form a rocket project team.

The Firearms Research Institute currently has three project teams: musket, cannon and grenade, which study musket, cannon and grenade.

The busiest one at present is the artillery research group, followed by the grenade research group, and the lightest one is the musket research group.

The tiger-headed rifle has almost reached the peak of the front-mounted rifle. The only places that can be improved are basically the only barrel left. The number of times the barrel is increased is mainly determined by the barrel material. The main force is the steel factory, and the musket project team is relatively easy.

Therefore, Ye Liangchou dispatched personnel to form a rocket project team, mainly recruiting personnel from the musket project team.

It took less than half a day to return to the Firearms Research Institute, and the construction of the rocket project team was completed. With Ye Liangchou, the entire rocket project team was only six, which was much less staff than the other three project teams. The main reason was that the rocket project was relatively simple.

Things were as Ye Liangchou thought. In just three days, the rocket project team completed the complete design of the rocket. The structure was slightly more complicated than the Dingtian Monkey, but it was not much complicated.

The rocket has been designed, and the next step is to build rockets. The firearms institute is basically full of researchers. Strong research ability does not mean strong hands-on ability. The task of creating rockets according to the design drawings must be left to the skilled craftsmen.

The Firearms Research Institute is adjacent to the Foshan Arsenal. Some of the Foshan Arsenals are skilled craftsmen. After the Firearms Research Institute contacted the Foshan Arsenal, several craftsmen were immediately dispatched to accept the command of the Firearms Research Institute.

The design of the first version of the rocket projectile was relatively simple. In just two days, the craftsmen built three projectiles under the command of researchers. The projectile was more than one meter long and about eight centimeters in diameter.

The researchers and craftsmen moved the bullet to an open test site, loaded the propelled gunpowder into the bullet, and began the first test of the rocket.

The rocket was placed obliquely on a suggested launcher at a thirty-degree angle.

"ignition!"

In about ten seconds, the fuse was burned out, and the gunpowder in the rocket body began to burn, and the flames ejected from the tail of the rocket, and the rocket shot up. However, the big diamond monkey flew in the sky for only one time, lost power in two seconds, and quickly fell to the ground. The falling position was only more than fifty meters away from the launch site.

The distance is more than fifty meters very close. If the grenade ejection device of the siege car is improved, the range of more than fifty meters may be reached at the farthest distance, so the rocket will not show its function. The rocket must have a range of more than one hundred meters before it can play a role.

Fortunately, the research on rockets has only been in the first few days, and it will take several months or even more than half a year to improve the rockets and research and create rockets that can be put into actual combat.

Ye Liangchou stayed in the rocket project team for less than ten days, and returned to his previous mission and handed over the rocket research work to Duan Kun, the leader of the project team. Compared with a simple rocket project, Ye Liangchou's other mission is more difficult and its role is greater than that of a rocket.

The musket project team is studying the improvement of muskets, and the grenade project team is studying the improvement of grenades, but the artillery project team is not improving the Folang machine cannon and tiger head cannon currently used by the People's Army, but is studying a new type of artillery, or more accurately, a new shell.

At present, the People's Army artillery mainly uses solid shells, followed by shotguns.

The range of solid shells is long, with a maximum of more than 2,000 meters, but the lethality is insufficient. Solid shells mainly cause penetration injuries to the enemy. The shells directly penetrate the human body. On the battlefield, a solid shell can even penetrate several enemies in a row. There are scars as big as bowls on the body, so it is impossible to survive.

A solid shell pierces several enemies when they are very lucky, and most of the time they can only hit one person or hit the open space.

Even if the solid shells have a long range, their function is far less than that of muskets on the battlefield.

If it is a shotgun, the range of shotgun is only about one hundred meters, but the coverage range of one shot is very large, with one shot and one shot, which is full of lethality.

Solid shells and shotguns have obvious disadvantages. One is that they have a long range and weak lethality, and the other is that they have a large lethality but a short range. The People's Army very much needs a shell with a long range and a large enough lethality.

Fang Nan thought of a shell, commonly known as "flowering bullet", which is correctly called "grenade". The biggest feature of flowering bullets is explosion. The shrapnel generated by the explosion can cause huge damage to the enemy within a certain range, and at the same time it has sufficient range.

Fang Nan handed over the task of studying grenades to the Firearms Research Institute. Previously, Ye Liangchou personally led the artillery project team to study the grenades.

If you want to study grenades, the most important thing is the fuse of the grenade. The fuse of the grenades used in modern wars cannot be studied by the People's Army, but the fuse of the early flowering bullets is relatively simple.

The early fuze of the flowering bullet was a hollow wooden tube filled with a densely pressed hard black gunpowder column (the pressed density black gunpowder burned very stable), and it can also be called a shell's signal tube. Before firing, a piece of the signal tube needs to be cut off or holes are drilled outside the scale of the fuze tube to calibrate the combustion time.

The shell is a cast hollow metal ball, filled with fine-grained black gunpowder, and then the wooden signal tube is loaded at the front end of the shell before firing (suffered into the shell fuze hole).

However, there needs to be a wooden bullet bracket behind the shell. This wooden egg bracket can prevent the shell from rolling unstable during the bore (because there is no egg bracket, the shell will rub against the inner wall of the barrel, causing the shell to roll around randomly. If the fuse is facing the burning high-pressure gas at this time, the fuse will be pressed into the bullet body and exploded directly).

During the bore, high-temperature gas will leak from the gap between the shell and the barrel to the front of the shell to ignite the fuse, so that the shell will be ignited during the bore, and the shell will explode after flying out of the muzzle for a calibration time.

In fact, some of the rockets and flowering bombs are the same. They can explode when fired, but the rockets have a relatively close range, which is because they are easy to use. The flowering bombs have a long range. The speed of the cannon loading flowering bombs is relatively slow, and the firing frequency is far from comparable to that of the mother-child cannons such as the Flang machine cannon.

According to the distance of the target, the flowering shell needs to be cut off or drilled holes on the scale outside the tube of the fuse to calibrate the combustion time. If not done properly, the flowering shell will only explode after it lands for several seconds. If it is put into naval battle, the shell will hit the enemy ship and bounce it for a distance before it explodes, which will not have much killing effect on the enemy at all.

Flowering bullets have various disadvantages, but in the future, the cannon that fires flowering bullets will replace the Flor cannon.

Due to the power and function of flowering bullets, the Firearms Research Institute will devote more personnel to the research of flowering bullets, and also study cannons that fire flowering bullets. The research difficulty of shells is greater than that of cannons.
