The admiration among the audience was not unreasonable. The No. 2 recoilless artillery gun in Tang Jixian's hand was completely dark green, and the several connections were made perfectly at the beginning. They all flowed naturally in streamlined and smooth curves. From a distance,

It gives people a sense of quality and beauty. If it were just this, it would not amaze everyone in the audience, because this is at best a very artistic green iron pipe, but it is still far from a real weapon and equipment.

What is more critical is the overall structure. Needless to say, the slender launch tube, but as for the reinforcement structure on the tube body and the flame balance device at the tail, a discerning person will know at a glance that this is called the "No. 2 recoilless launcher"

Artillery's individual rocket launcher is by no means an ordinary product with no merits.

Since Germany's "Iron Fist" series of individual rocket launchers pioneered super-caliber ammunition during World War II, how to launch powerful ammunition with larger calibers farther has become the direction of unremitting efforts by military industry experts from various countries.

Over the past few years, military industry experts have indeed found many solutions, such as reducing the metal components of the projectile body and reducing the overall weight; for example, developing more efficient propellants and shaped explosives to fundamentally solve the problem of ammunition range and

However, no matter how it is solved, there is a problem that can never be circumvented, and that is the endurance of the individual rocket launcher.

As we all know, in order to reduce the manufacturing cost of individual rocket launchers, all military powers basically use relatively cheap seamless steel pipes for such equipment. However, the durability of the rocket launchers is a huge problem. Like Germany, they just throw them away after being shot.

Fortunately, if you continue to use it, you have to consider the corrosion and burning of the launch tube body caused by the high temperature and high pressure generated by the rocket wake.

If this problem cannot be solved, no matter how powerful the ammunition is, no matter how far the range is, it is impossible for soldiers to risk injury or even their lives to operate a rocket launcher that is easy to explode. Based on this, how to strengthen the rocket launcher tube body?

, as well as efficiently and fully guiding the discharge of the rocket wake, have become the top priority of the reusable rocket launcher.

For this reason, Americans who are good at technical flow solved this problem with the pure rocket balance principle, which is simple in form but creates troubles. Thus, there are "Bazooka" and "Super Bazooka", but this method is very good.

Solve the problem of balancing the ammunition and the tube body, but the caliber of the ammunition is strictly limited by the tube body. There is no way to use super caliber, and the upgrade potential is very limited.

The Soviet Union did not follow the path of the Americans. Instead, after fully learning from the advanced experience of the Germans, it summed up its own method, which was to use strong metal components to repair the middle and rear parts of the launch tube that were most severely exposed to high temperatures and pressures.

The secondary strengthening treatment can not only stabilize the barrel so that it can be used with more powerful super-calibers, but it can also be used as a heat insulation device to prevent shooters from being burned by high-temperature heat flow.

Therefore, people can see the pure wood-colored tube reinforcement structure in the middle and rear of the launch tube of RPG-2, which is to better adapt to super-caliber high-power ammunition, but RPG-2 is certainly ahead of the curve in this regard.

At the forefront of the world, but not perfect.

Based on the shackles of the original design, the reinforced structure of the RPG-2 is not omnipotent. The reason is that in addition to the initial design shortcomings, the balance principle of the recoilless artillery has not been fully developed, so that the high temperature of the rocket

The high pressure cannot be discharged in a timely and effective manner at all, and remains in the pipe body for too long, causing the external reinforcement structure to be unable to withstand cracks in the internal pipe wall, no matter how effective it is.

Because of this, the propellant of RPG-2 has always used old black powder. The reason is simply because the burning effect of black powder is the lowest among many propellants. But it is also because of the use of black powder as propellant.

The range of the RPG-2 is only a miserable 100 meters.

In other words, except for the optimized structure and weight of rpg-2, the overall performance is not essentially different from the "Iron Fist" 100 used by Germany in the late World War II. It was not until rpg-2v2 that benefited from the treatment of the tail.

It has been slightly improved, but the overall shortcomings have not been fundamentally changed.

On the other hand, China's No. 2 recoilless artillery, like a swan's neck, the 40mm front launch tube is swept back rapidly, and it is a whole reinforced structure that almost runs through the middle and rear. Judging from the thickness, it looks like a muscle knot.

It's about 10mm at least. If it's just that, people might be surprised, but they won't be surprised or even shocked.

The reason for this is mainly due to the treatment of the rear section of the No. 2 recoilless gun, because it does not extend straight like the RPG-2, but quickly retracts into a 40mm diameter reinforced tube after the bulge, and then

It expands rapidly and forms a bell-shaped tail nozzle at the tail.

Seeing this result, anyone who has been in the military for a long time can tell that this is the most classic recoilless artillery structure. Although it has been slightly changed to be suitable for individual combat, the rapid

The heat flow duct and the bell-mouth balance nozzle are the most basic balancing principle of the recoilless artillery!

Until this time, everyone in the audience finally understood why China called its individual rocket launcher No. 2 recoilless artillery. I bet the Chinese just transformed the recoilless artillery into individual soldiers, thus evolving their own individual rocket launcher!

Haven’t the officers and military technical experts present thought about this simple and effective recoilless artillery structure? Of course not. The problem is that the simple principle does not mean it can be built. The basic principle of the turbofan engine is very simple and simple.

Ordinary high school students can tell one, two, and three.

But it is even more difficult to build a good turbofan engine. The same goes for developing individual rocket launchers using the structural principles of recoilless artillery. It cannot be done by the heroic Qianyun with a simple introduction of principles, but requires an extreme amount of effort.

Complicated calculations, quite complex technical analysis and countless tests, evaluations and experiments, it can be said that it would be impossible to really figure it out without several years of hard work.

But now, China's No. 2 recoilless artillery is standing on the shooting range like an impassioned handsome man, causing everyone in the venue to look at the crude RPG-2v2 for a while, and for a while to look at the domineering No. 2.

No recoil-powered artillery will make your head messy.

Because compared with others, RPG-2v2 is even more rubbish than a rubbish, so that the officers of these Eastern European satellite countries who had previously cheered for Soviet equipment felt a little embarrassed. If they had known that there were tall, rich and handsome people, why would they praise those who were short and poor?

Hey, aren't you looking for abuse yourself?

Of course, they are ashamed. The things behind the No. 2 recoilless artillery are what they look forward to the most. Not to mention anything else, but the complete principle of recoilless artillery is enough for these Eastern Europeans with high eyesight.
