"The whole world of armored doors" (Ukraine) against RPG

95
New tests of anti-cumulative screens for armored vehicles in Ukraine, organized by the company "The whole world armored door"
Further explanatory text, videos and photos from the site of the company:




Enterprise "The whole world of armored doors" decided to help our armed forces in the fight against terrorism and Russian aggression: given the huge number of armored personnel carriers, especially the old model, unprotected from cumulative shots of anti-tank grenade launchers. By themselves, the old BTRs, from the words of the military, are quite good and reliable, but the lack of elementary protection against RPGs makes them a tasty target for enemy rocket launchers. The same situation with the BMP, BRDM and other Ukrainian armored vehicles.
Our welders in short recreated the anti-cumulative screen using the most common scheme - a metal grid with small cells for viewing, saving metal and, of course, a reasonable weight distribution. Since this is a matter of extreme importance for the army, and we didn’t have our own experience in creating and testing such screens, we didn’t pin special hopes on this first sample, rather we wanted to quickly take it to the landfill, shoot it, seeing what such cumulative shells and that they represent their consequences directly with their own eyes and do the work on the errors, which is also a fairly good result in itself, creating an improved screen afterwards taking into account all the nuances.

In the first sample of the anti-cumulative screen, the cells were metal strips of sufficiently thick metal located sideways to the armor and to possible projectiles at a vertical distance of no more than 65-70 mm from each other and up to 350 mm in the horizontal plane of the screen.
To test the effectiveness of the screen, we also created a sample that simplifiedly simulates the armor of a potential armored personnel carrier. We deliberately made the sample weaker than real armor, in order to strive for better results.
By analogy with the main sample of the screen, we created several small "screens" of a different design.

"The whole world of armored doors" (Ukraine) against RPG

Granatomotchiki brought with 40 mm grenade launcher RPG-7 from 4 cumulative shots and disposable anti-tank grenade launcher with a cumulative charge: 2 64 pieces mm RPG-18 "Fly" and the same number 72 22-mm RPG "net". Shoot decided to increase combat power. The first in business decided to experience the legendary "fly".
They decided to shoot from a distance of 50 meters. The first shot showed an enormous value of the size of the cell of the anti-cumulative screen, it must be subcaliber, otherwise the grenade will simply fly between the walls of the cell and the screen simply will not show itself at all.



64 mm grenade at a speed of up to hundreds of meters just squeezed between the guides (clearly seen in the video), forcing them to unscrew slightly, which prompted the output to reduce the horizontal distance between the vertical edges of the screen. In fact, having flown the screen, the grenade successfully penetrated our improvised armor.

Coming closer after the shot, those present not only saw how the grenade broke through the target, but also that it overturned the target and the protective screen against cumulative projectiles on the ground. Here is such a force of the explosion:

Shooting RPG-22:
Surprisingly, the grenade ... Just broke, meeting our protective screen at speed along its path. There was no explosion as such, but the phlegmazitized heat-resistant HKT, it was okfol, an explosive for the formation of a cumulative jet, stuffed in a grenade just scattered into pieces near our target of the anti-cumulative screen.
Judging by the video footage and the performance characteristics of the grenade launcher, the grenade flew up to the target at a speed slightly higher than 100 М / С, that is, the impulse of the grenade was very high - about 135-150 КГ × М / С. With such motion parameters, if we assume that the grenade’s fuse mechanism was broken tangentially about the edge of the anti-cumulative screen cell with such a powerful impact, it becomes clear why there was no detonation. The video shows quite well how at the moment of the collision of a grenade with a grill a small shiny part goes up from the extreme point of the grenade. Part of the design of the fuse? Unknown. To say exactly why the detonation failed, probably, no one will undertake. Even the production defect can not be written off either. In any case, this situation shows excellent steady qualities of okfol.

What about our armor BTR? And the armor did not even suffer, because the target was only a blow, in fact, ~ 1,3 kg of blank.


Shooting RPG-7:
The first shot from the RPG-7, unfortunately, went a little above the protective anti-cumulative screen. No one went to watch and immediately unanimously decided to prepare for the next shot.



The second shot pleased us: clearly on target! A powerful grenade not only broke the strip of rigidity of the screen and the edges of the cell, but also broke through a decent hole in an armored target.



The jet was so powerful that it broke through the anti-cumulative grille, and armor, and beautifully entered the sand parapet. In the place where the cumulative beam entered the sand sintering of the sand occurred under the action of high temperatures.





Additional shots RPG-18 and RPG-22 on the anti-cumulative grille:
The second shot turned out to be no less interesting: the grenade didn’t reach the target for a while and, bouncing off the ground, did not explode, hit the target sideways, there was an explosion, and the cumulative jet went into the ground.
A powerful explosion destroyed the cell guides of the anti-cumulative grid, and the resulting cumulative jet even slightly hooked the bottom edges of the screen, tearing them off without any problems, since the direction of the impact was not from the side, but from top to bottom at a slight angle around 15.





Again, you can clearly see how sand is caked into pieces (silica or SiO2). The target itself, located behind the anti-cumulative screen, practically did not suffer as a result of such an explosion.




The 72 mm RPG-22 "Net" grenade was stopped with an anti-cumulative screen, but the cumulative jet broke the edges of the cell and reached the target, but due to the fact that the axis of the jet intersected the plane of the target at its extreme point, it turned out not a hole, but only a semicircle, like a crescent.




Screen after firing


On the website they write that two more tests of the converted screens have been carried out, they have allegedly already gone to the finish line before the production.

      Yes, as it were, the problem of protecting armored vehicles from RPGs is not purely Ukrainian. It is relevant for the Russian Federation, as well as for other countries. And military conflicts are a practical training ground for decisions in this area. The effectiveness of certain solutions is tested in real, not test conditions. And on the basis of this, we can draw conclusions and conduct new developments.

    Similar means of protection are used in many armies of the world, including against the defense of anti-tank weapons of Soviet-made models (Iraq, Afghanistan, Syria and, more recently, Dill).

    .RPG-18 is for concrete structures. RPG-7 is for armored ones. There were earlier "specialists" who tried to find protection from RPG-7 shots. Look at its performance characteristics. It burns armor up to 600mm. Smart designers created it, look around this weapon is used everywhere in the world. Better, not invented. In order for the commutative jet not to work, you also need a layer on the armor or "active" protection. allowing you to spray the jet.

      The lattice must be made of high alloy steel with a tensile strength of 1200 MPA and behind it two sheets of VT-32 titanium alloy with a thickness of 12 millimeters, the distance between the sheets is 16 centimeters. And then even a shot of the PG 7V will be held.

        In general, the point of the lattice is not to "move" the focus of the cumulative jet from the main armor, but to prevent the grenade from firing. This is achieved by damaging the warhead of the missile on the lattice strips.
        As if a grenade was being passed through an egg-cutter. Screens, especially from titanium, are not needed.
        But the rigidity and elasticity of the lattice would not hurt to increase.
        I think from available materials spring steel of grades: 60С2А or 65Г would be suitable.

    The first shot from the RPG-7, unfortunately, went a little higher than the protective anti-cumulative screen

        sovkovskaya technique let them down!

        And this is not the first time!
        On October 4 of 2001, the rocket did not understand Ridna mov, she only understood Russian, as a result it exploded at an altitude of 11000 m and the Tu-154 plane crashed into the Black Sea
        The assumption that the passenger plane was shot down by mistake of one of these missiles, the Ukrainian side rejected with indignation. And Russian President Vladimir Putin said that he ruled out the possibility that the Tu-154 was shot down by Ukrainian air defense forces. The Minister of Defense of Russia was of the same opinion. The version about the impossibility of such a thing was regularly repeated - even though the Ukrainian prime minister himself recognized the likelihood of such an opportunity.
        However, two days later, the Pentagon confirmed that its satellite tracking means recorded missile launches precisely in the area of ​​the death of the aircraft. Then the Minister of Defense of Russia announced that President Putin was not satisfied with the data of the Ukrainian side and requested more detailed information. Here the question cannot but arise, on the basis of what information (and, most importantly, by whom it was provided) made his statement that the plane could not be shot down by a “crazy” Ukrainian missile, President Putin.

          Two months later
          The emergency incident with the Tu-154M RA-85693 aircraft occurred as a result of the defeat of the aircraft by the combat unit 5B14Sh of the 5V28 missile of the S-200V anti-aircraft complex, which launched during the exercises of the Ukrainian air defense forces from a position located in the vicinity of the city of Feodosia on the Crimean peninsula.

    To improve the protection of the LBT from cumulative grenades of the RPG-7 type, it is necessary to install the RE not horizontally to the armored hull, but V figuratively, at an angle of not less than 70% of the normal, which will increase the likelihood of a rebound and remote detonation of the grenade. To reduce the impact of the COP on the armored personnel carrier in case of undermining, install rubber-reinforced or steel shields 15–20 cm from the electronic components.

    Well, as for "those who save", let them work. One head is good, but a lot is better.
    If you noticed a bunch of articles about "development", let some cause laughter, but there are very necessary ones.

        Tsialkovsky made the calculation of the rocket for space flight ~ 100 years ago, but only 6 countries in the world were able to bring it to life

        Russian Research Institute of Steel http://www.niistali.ru/defence/armoureddefence?start=2
        Lattice screen - provides the probability of destruction of RPG grenade warheads (PG-7, PG-9) without the formation of a cumulative jet 0,5 ... 0,65 - These are very decent indicators.
        Ukrainian guys are not fools, I think they will be quickly reached ~ 0,33 and increase the protection of Ukrainian armored vehicles by a third.

        The most unpleasant thing is that our development with 0,5-0,65 did not go into series, and these Ukrainian businessmen are quite effective and can start production crying

    Against heavy machine guns, no lattices will help and landing of infantry is complicated by the use of lattices. The armored personnel carriers are intended for delivering infantry to the battlefield and for providing fire support to the latter, and not as advanced forces for opening defense. they are also effective in the counter-guerrilla warfare in the absence of serious weapons from the enemy. overloading the machine with iron and sandbags, the maneuverability of the armored personnel carrier is lost and turns into a stationary firing point, which in other circumstances is not critical in some conditions

      On the website they write that two more tests of the converted screens have been carried out, they have allegedly already gone to the finish line before the production.

      By the way, the idea came here, if we discard that this is Ukraine with all the consequences,

      this is a real featured test of their products,

      there were proposals for the protection of armored vehicles, special mats, nets with balls, but there wasn’t such a video for them.

    Unsolicited several conclusions:
    1) about filling heads - anti-cumulative screens have been known for many decades. Instead of taking advantage of world experience, dill decided to go their own independent way ...
    2) about the arrows - one grenade above passed another hit the ground. and this is from 50 meters ...
    3) it’s how they got so hot that they started to move assholes
    the first two conclusions I will not voice
