Helkir mine
Encyclopedia
The Helkir is an anti-helicopter mine developed by the Austrian company Hirtenberger. It uses an IR sensor and an acoustic sensor to detect airborne targets. Once the mine is armed and ready to engage, the acoustic sensor listens for a valid noise input. This enables the IR sensor which is located coaxially to the warhead
. When the IR sensor detects a hot signature, the mine blasts off fragments that can penetrate up to 6 mm of armored steel at 50 meters and 2 mm of mild steel
at 150 meters. The mine is active for a period of 1 to 120 days, after which it returns to a safe mode.
Helkir, as well as other mines developed by Hirtenberger, like the APM-1
and the APM-2
anti-personnel directional mines (discontinued in 1994) , do not appear on the companie's current website.
Warhead
The term warhead refers to the explosive material and detonator that is delivered by a missile, rocket, or torpedo.- Etymology :During the early development of naval torpedoes, they could be equipped with an inert payload that was intended for use during training, test firing and exercises. This...

Steel
Steel is an alloy that consists mostly of iron and has a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most common alloying material for iron, but various other alloying elements are used, such as manganese, chromium, vanadium, and tungsten...

APM series directional fragmentation mines
The APM-1, APM-2, APM-3, APM 19, and APM 29 are Austrian directional fragmentation mines similar to the U.S. Claymore mine. The mine's cases are made from moulded plastic have convex faces. They contain a matrix of 5 millimeter diameter steel balls weighing 0.5 grams laid over a Composition B charge...
