Definitions
- the present invention is related to a flexible web used to confront Rocket Propelled Grenades (RPGs).
- RPGs Rocket Propelled Grenades
- This invention is suitable for protecting static or mobile objects and especially buildings, e.g. Embassies, governmental buildings etc against attacks made with Rocket Propelled Grenades.
- the protection of a particular target from RPGs is accomplished by covering it with the flexible web of the present invention.
- the protection of the referred constructions is achieved by the instantaneous mechanical damage of the outer metallic ogive of the grenade exactly at the same time as it impacts on the protective web, due to its high momentum.
- RPGs type 7 are cheap, easy to find, very popular and extremely lethal weapons.
- the attack of a target by an RPG of this type results to its total destruction and for that reason they are mainly used against vehicles, battle tanks and helicopters.
- the present invention refers to a flexible web capable to protect vehicles, helicopters and buildings from RPGs.
- the flexible web of the invention does not require any kind of electronic device to support its operation, is very flexible and its weight is approx. less than 4 kg / m .
- the RPGs 1 protective web is very easily installed in the outer surface of any kind of buildings, and therefore is ideal for the protection against terrorist attacks in high security buildings such as embassies, military installations, government buildings, industries etc.
- the protective web is placed on the outside surface of the object required to be protected and in a small standoff distance, few centimeters are adequate.
- the present invention can be manufactured in multiple dimensions without the need of frames. It is so flexible that it can be rolled and unrolled very quickly.
- the present invention consists of at least one grid (1) upon which the incoming grenades collide.
- the grid (1) of the protective web is formed by strings (2).
- the diameter of the strings (2) can be from 2 to 10mm.
- solid connectors (3) are placed, retaining the strings in place.
- suitable materials for manufacturing the strings (2) are metals, or metallic threads of variable strength, or metallic alloys or synthetic materials of high breaking strength (like carbon fibers or/and dyneema or/and steel rope) or any possible combination of the above materials.
- the protective web of the present invention is designed in such a way so that the empty spaces of the meshes (4) of the grid cannot be less than 55mm. Specifically, those empty spaces may have square or rectangular shape, though any other formulation and shape of the mesh is possible.
- the solid connectors (3) that restrain the strings (2) of the grid (1) can be manufactured of material of high specific weight and hardness.
- the smallest possible dimension of the solid connectors (3) that restrain the strings (2) is 6mm and the biggest is 30mm.
- the present invention is necessary for an easy and quickly protection of many mobile and real estate assets, automotive and remote-controlled constructions, premises and military or civilian equipment that are targeted with RPGs. It is also used to protect armored or not vehicles, airplanes, boats and window glasses from attacks by RPGs. It is necessary for the immediate and safe mechanical destruction of launched lethal RPGs 7 grenades, used to destroy the targets we wish to protect.
- the RPGs-7's web protection operates like a protective shield against RPG-7 grenades' collision, but not against grenades of the NADER type or similar.
- the protective web for countering RPGs according to the present invention has many advantages.
- the web does not use explosives, chemical or toxic substances, laser beams, nuclear energy, or electric energy nor any kind of emitted radiofrequencies or other kind of electromagnetic radiation to achieve its results. Its use is safe and there is no danger of causing unwanted injuries or even collateral loses.
- the present invention has the ability to resist to several hits of RPGs without losing its effectiveness.
- the flexible web is transparent so that people being on the inside of the object that covers can see outside, for example in a vehicle.
- the RPG after launch has very high momentum and when it impacts on the web has a great force.
- the solid connectors that retain the strings and the strings themselves also, cause mechanical destruction of the grenade's ogive.
- the forces applied on the points where the metallic ogive of the grenade touches the web cause direct compression of the ogive at those points. Consequently, the destruction of the main body of the grenade is achieved and also of the hollow charge and of the electrical conductors that transfer the detonation command from the piezoelectric crystal, located at the tip of the grenade, to the detonator. This is achieved because the tip of the grenade, where the piezoelectric crystal is located, enters the empty spaces of the web i.e. the grenade is deactivated before it detonates.
