As an important part of the individual protection system, the combat effectiveness of bulletproof helmets has been fully affirmed in previous local wars and high-tech local wars. At present, police equipment companies across the country are sparing no effort to develop a new generation of multi-functional and high-performance bulletproof helmets to meet the operational needs of future high-tech warfare.
Bulletproof helmets are not actually bulletproof, they can only be bulletproof, and rifle bullets can easily penetrate various military bulletproof helmets within the effective range, and they are two eyes. Therefore, it is very important to choose a helmet with strong protection ability. So, how to measure the protective ability of a helmet. The quality of the helmet is usually measured by three indicators, that is, the V50 speed value, the protective area and the weight. The material is not considered, it is a helmet made of galvanized iron, as long as the above three indicators are qualified, it is also a good helmet. Among them, the V50 speed value is the most important measure.
The so-called V50 value is to use a hypotenuse cylindrical projectile with a mass of 1.1 grams, shoot the helmet at different speeds within the specified distance, if 50% of the projectile penetrates the helmet and 50% does not break down, that is, the probability of breakdown is 50%, and the average speed of the fired bullet is the V50 value of the helmet. The higher the V50 value, the better the ballistic performance of the helmet.
Bulletproof helmet is an extremely important protective equipment in the combat process, so you must be extremely cautious when choosing, the better the quality, the more life is guaranteed, and you must not take it lightly.
