The development of bulletproof helmets for the Russian army
On May 9, 2008, on the anniversary of the victory of the anti fascist Patriotic War, the Russian armed forces held a grand military parade in red square, Moscow, and all the major heavy combat weapons of the Russian army appeared on the stage. Due to aesthetic fatigue, Benson has little interest in these weapons which can be seen everywhere. The only bright spot is the new aramid helmet recently issued by the Russian army. Perhaps it is because the disintegration of the Soviet Union has led to economic distress in the past 17 years. At a time when major military powers (including China) in the world have eliminated old helmets with composite fiber helmets, as the field forces of the former Superpower Russia's armed forces, they still use a large number of metal helmets that have been equipped for 40 years. Therefore, this is not a small change The Russian economy is recovering and the strength of the Russian army is recovering.
I have nothing to do in the evening. I'd like to write a brief paragraph to introduce the new type of bolit series general bulletproof helmets displayed by the Russian army during the Victory Day parade. With the United States as the representative of the western countries in the 1980s began to install a new generation of Kevlar helmets, the old metal helmets of the former Soviet Union will also face the problem of elimination. The Soviet army also began to study new helmets in the 1980s. Due to the blockade of aramid fiber material technology by the former Soviet Union and Russia by the United States, Europe and NATO, the early developed models such as 6b14 were all improvements to the old-fashioned ssh-68, and their performance did not make a qualitative leap, so they all failed. At the end of 1990s, Russia's aramid fiber technology finally made a breakthrough and developed the first composite helmet 6b7. Although the helmet weighs 1.5kg and the initial production cost is as high as US $400, which is twice as expensive as the similar products in Europe and the United States, 6b7-1, 6b7-1m and 6b7-1a have been developed with continuous improvement, such as 6b7-1, 6b7-1m and 6b7-1a wait. At this time, Russia's economy was in the most difficult period, and the army was unable to update the old helmets, so things were delayed.
With Putin's coming to power and the improvement of Russian economic situation, the Russian army began to have the ability to pay attention to the appearance, material, quality and performance of individual protective equipment in recent years in Chechnya and other wars. In order to solve these problems, the Russian army has taken a series of organizational and technical measures in recent years. Since 2001, the project has been approved for research and development. In 2003, the bolit-m series of general bulletproof helmets (the product code is still 6b7, and the name of the product is орит). Now, this series of helmets have passed various tests and are equipped with field motorized troops and armored forces. However, the Russian Ministry of internal affairs and other powerful organs engaged in public security and anti-terrorism do not seem to replace the tsh-5 and K series helmets with belite-m helmets.
This series of helmets are manufactured by three enterprises. There are subtle differences between the products of different companies. There are also commercial versions for civil defense or paramilitary operations. The Russian army hopes to gradually replace the ssh-68 helmet which has been equipped for nearly 40 years with bolit series general bulletproof helmets in a few years.
So far, the Belite series of general bulletproof helmets have many development models, including 6B7-1, 6B7-1M, 6B26, 6B27, 6B28 and other types. In fact, Russians often confuse these two helmets. It's hard to tell. (Published by Korolev) 6B7-1 helmet main performance:
The total weight is 1.2 kg. The protective area is 13 square decimeters. It can defend against 9 mm 57-Н-181С bullets fired by a BM or TT pistol with a muzzle velocity of 315 m/s at a distance of 5 meters. The V50 can effectively defend against fragments of a hypotenuse cylindrical projectile with a mass of 1 gram with a muzzle velocity of 580 m/s (V50 value = 580). The new generation Армос aramid fiber material is used, the suspension device adopts a belt system, and the chin rest is woven with leather (sic). The helmet can be securely fastened to the soldier's head at any time to maintain the protective performance. The temperature range is from -50°C to 50°C, other anti-chemical, anti-virus and communication devices can be added conveniently. Equipped with two camouflage covers in summer and winter. The 6B7-1 helmet also has a lightweight development type called 6B7-1A, which weighs 0.9 kg.
The main performance of 6B7-1M helmet:
The total weight is 1.25 kg. The protective area is 12.7 square decimeters. Excellent defense performance, can defend against 9 mm 57-Н-181С pistol bullets with a muzzle velocity of 315 m/s, and V50 can effectively defend against fragments of a hypotenuse cylindrical projectile with a mass of 1 gram with a muzzle velocity of 650 m/s (V50 value=650). The suspension device adopts a three-point type, and the material adopts a special waterproof treated aramid fiber material, which has an anti-ballistic performance that is twice that of the original old steel helmet. Except for the slightly smaller protective area, other performance indicators are similar to those of the 6B7-1 helmet.
The appearance of the two helmets is slightly different. The 6B7-1 helmet uses a leather jaw rest, while the 6B7-1M helmet uses a plastic jaw rest. The number of rivets is also different (6B7-1 is 6 rivets, 6B7-1M is 3 rivets), the protruding part of the 6B7-1M ear guard is approximately square, while the 6B7-1 helmet is approximately oval. In terms of helmet type, 6B7-1M is closer to the helmet type of Europe, America and China, and the appearance is better. The 6B7-1 helmet looks more rounded. The main reason is to keep the gap between the helmet and the soldier's head as consistent as possible, so that the wearer can be protected to the greatest extent when the helmet is deformed by shrapnel.
In 2006, the Russian army launched an improved Belite helmet. The new helmet is divided into three models: 6B26, 6B27, and 6B28. In this way, the Russian helmet model entered an era of as complicated as Russian tanks. Type 6B26 is a light helmet with a weight of only 0.95 kg. The 6B27 is a normal model and weighs 1.25 kg. 6B28 is an airborne type. The V50 value of the three kinds of helmets is 600-650 m/s, and the protection area ranges from 11 to 13 square decimeters.
