Advanced protection for military vehicles (part 1)

Advanced protection for military vehicles (part 1)After learning the introduction of martial technique, whether wheeled or tracked, the current level of protection of the automobile, is in great demand.

Namely, the wars in Iraq and Afghanistan have shown that critical situations can often be resolved only with the introduction of languid combat vehicles. Because terrorist threat may come with at least some areas, cars are required to have strong radial protection.

During the collapse of the Warsaw contract, euphoric idea that global threat overcome and there is peace in the world rapidly spread throughout Europe. Senior military bureaucrats believed that the armed forces can be reduced to the level of police with light infantry weapons. Tanks and armored personnel carriers, which until that time were at least some army base, overall dinosaurs have become a political ice age and, as a thing of the past. Many would willingly would refuse it.

The Balkan conflict operations in Africa, the war in Iraq, the military action in the Middle East and, in the near future, the war in Afghanistan showed that the political an advantage in this globalized world, can only be achieved by active and sustainable armed forces within NATO countries. These conflicts were also given to understand that the army should be armed with enough languid weapons systems to ensure the highest level of support for their own troops in the open or sheltered combat, and the ability to have the highest intelligence, firepower, mobility and protection.

Passive armor, which in the main is now used as a suspended or built-in parts, often leads to a considerable increase of weight while reducing the mobility and payload. With all this protection, obespetsivaemy passive armor, has its limits.

Direction, type, efficiency, and implementation strategy of attacking means of hidden terrorist ambush radically changed. So Makarov, the standard STANAG 4569 is not a sufficient control to protect against threats to close to reality. Now ballistic and mine threats are more versatile and more powerful. Standardized risk urban combat operations, such as hand-held weapon systems family of RPG-7, including the RPG-30 anti-tank and anti-missiles, anti-tank hand grenades RCU-3, improvised explosive devices and charges from the EFP at the present time can not be systematically classified. Because of the wrong policies of confidentiality is often only a finite machine manufacturer, not the developers involved in the assessment of the protection of attacks, and it has a bad effect. In addition, the fact that different hazards, such as, for example, infantry ammunition, cumulative shells, improvised explosive devices and charges from the EFP, often operate on the surface of the machine must be taken into account when developing the concept of protection. To counter such threats need to use different materials. For example, steel armor great for protection from infantry weapons, but least useful against shaped heads and RPG rockets, and even against the charges from the EFP.

On the basis of its own assessment of the experience of the operations of many countries have their own special aspects and guidelines for the formation of the requirements, testing, certification, which should provide sufficient protection.

Aspects of organizing protection

Protection system must be classified depending on their performance, so they are comparable together. In accordance with the present state of technology is closest to the reality of systematization into three classes, depending on the type of effect. Increasing importance in assessing the protection of the ability of anti-receive systems and prevention of repeated acts of collateral damage.

Passive protection provides significant resistance to repeated impact and, in addition, does not cause huge damage around him. In almost all cases, a reservation of 1st particular type of material such as, for example, metal, glass fiber, ceramics and others. With all of this has lined to reduce the effect zabronevogo used occasionally.

Now a combined solution that provides the highest level of protection is more effective. It is associated with the introduction of various materials, their rassredotachivaniem and a certain disposition, by the establishment of synergy effects. This solution provides a reduction of weight. And Modifications form, namely, in the case of mine protection, can have a significant impact on the effectiveness of the protection.

Big threat to armored vehicles from the RPG warheads with shaped led to the development of reactive armor. It is an armor set, containing explosives, spread around the tower, and the front of the chassis. Countermeasures have caused searches to overcome these kinds of protection. Shaped charge, getting into a dynamic armor and causing its operation, leaving the affected area and the coming of her entourage defenseless against repeated defeats. So makarom protection ammunition against the tandem is not guaranteed. In other words, such type of armor does not protect against repeated exposure. The method of growth of the number of layers belonging to the same set of armor, the protection level can be increased. But it does not protect against RPG-30. In addition, the explosion when triggered reactive armor is a severe danger to people or the vehicle, which are placed close to the target machine.

Due to the enormous weight of reactive armor sets, in the best case, it increases the protection of the least than 75%, and the side effects that occur with reactive armor do prepyadstviya crew as well as transmitting the forces. All this has affected namely in conflicts in the Middle East. Especially in urban combat, where the use of reactive armor has significant drawbacks, and in some cases has led to an impressive total destruction of the machine.

Since the late 1970s, the Armed Forces of the USSR developed active protection system, which was found to have identified and destroyed the approaching danger before they impact on the machine. This idea was quickly picked up by Western military forces. Active protection system can be classified into the system Myagenko (soft-kill) and rigid (hard-kill) resistance. In this case the system hard counter may, in turn, are divided in accordance with their time response.

System soft-kill (of opt
ronic countermeasures), such as MUSS company EADS, may counteract the only manageable and homing missiles, produced from a great distance. The method of aerosol screen laying or other countermeasures, the system hides the car and takes the projectile from the target. In this case, the collateral damage from uncontrolled danger of self-destruction can not be ruled out. Soft-kill systems are not suitable for protection against infantry fire, anti-tank rocket-propelled grenades or rockets. Such systems are comparable to a huge response time because effective against rockets fired from great distances, because such systems are not effective in the criteria for urban operations.

System of hard-kill, usually categorized by the distance at which the interception is carried goals, which corresponds to the speed of the system. On this basis, they are divided on the system with the highest (microseconds), medium and low (milliseconds) performance.

System close active protection act, the production of IBD Deisenroth Engineering, different from all the others is not only a short distance (10 m), which is affected by a projectile flying up. It also has a central sensor system which can be centrally disabled. System has the possibility of multiple actions at the expense of effective overlapping areas. It can be installed on relatively light armored vehicles, and the languid tanks, providing a radial protection in the entire upper hemisphere. Weight system for light combat aircraft is within 140 kg and 500 kg — for the heavy equipment.

More vserasprostranennymi medium-range systems are the Russian Drozd and Arena-E, which are the first generation systems and the danger of destroying small shells. IRON FIST, TROPHY and LEDS 150, by opposing the explosion, also AWiSS production Diehl, providing a burst of damage and fragmentation grenades are more exhaust systems in third generation. All these systems are triggered within a millisecond, are applicable only to middle and languid fighting vehicles because of their enormous weight and features of the architecture. Configurations for light combat vehicles with a weight of 350-500 kg in the current being developed. These systems are effective at distances exceeding 60 meters so that they can be used is limited in the criteria of the town. But the real attack in the town of Conception pass with smaller distances, and in such cases they do not have time to work and it is impossible to apply them.
