A soldier examines two inverted VS-1.6 blast-resistant anti-tank landmines. Cut-away view of a VS-MK2 blast-resistant anti-personnel mine. A blast resistant mine is a landmine (intended for anti-tank or anti-personnel purposes) with a fuze which is designed to be insensitive to the shock wave from a nearby explosion.
Zetix is a fabric invented by Auxetics Technologies, Ltd., a UK company. Zetix is an auxetic material strong enough to absorb and disperse shockwaves from explosions without breaking. [ 1 ]
The VS-2.2, VS-3.6 and SH-55 are Italian circular plastic cased anti-tank blast mines that use the VS-N series fuze. They have very few metal components and are resistant to overpressure and shock. The VS-2.2 and VS-3.6 can also be deployed from helicopters. It was produced by Valsella Meccanotecnica and Singapore, but production has ceased ...
Blast dampers usually employ some type of blade held open with tension from a spring. The damper blades close automatically when pressure overcomes the resistance offered by the spring. Various models differ in the amount of blast protection (e.g. 1 bar/14.5 psi or lower amounts of protection) and whether they stay closed after the blast or ...
Mine-Resistant Ambush Protected Vehicle (MRAPV), also known as MRAP Vehicle, is a type of armoured personnel carrier that are designed specifically to withstand land mines, improvised explosive device (IED) attacks and ambushes to save troops' lives.
Special footwear, including combat boots or so-called "blast boots", is only moderately protective against the destructive effects of blast mines, and the loss of a foot is a typical outcome. Blast mines have little effect on armoured vehicles, but can damage a wheeled vehicle if it runs directly over the mine.
Water resistance is measured by the amount of water, in mm, which can be suspended above the fabric before water seeps through. [ citation needed ] Breathability or moisture vapor transmission rate is measured by the rate at which water vapor passes through, in grams of water vapour per square meter of fabric per 24-hour period (g/m 2 /d), [ 2 ...
As water vapor passes through the plate and the fabric, it causes Evaporative Heat Loss and therefore more energy is needed to keep the plate at a constant temperature. Ret is the measurement of the resistance to evaporative heat loss. The lower the Ret value, the less resistance to moisture transfer and therefore higher breathability.
