Kaktus

Nikdy není pozdě rozkvést!
Povzbudivý román se svéráznou hlavní hrdinkou
Susan Greenová je nezávislá, samostatná a svůj život má naprosto pod kontrolou. Rozhodně nehodlá plýtvat časem na vztahy plné citových zmatků. Rodina i kolegové v práci ji sice považují za nepřístupnou a divnou, ale Susan tento uspořádaný způsob života dokonale vyhovuje. Jenže pak se vlivem nečekaných událostí začne její pečlivě vybudovaný řád hroutit a Susan si postupně uvědomuje, že nemůže ovládnout všechny aspekty svého osudu… a že to nemusí být špatně.


Kaktus - Sarah Haywood Summary

Kontakt-5 is a type of second-generation explosive reactive armour (ERA) originating in the Soviet Union. It is the first type of ERA that is effectively able to defeat modern armour-piercing fin-stabilized discarding sabot (APFSDS) rounds. Introduced on the T-80U tank in 1985, Kontakt-5 is made up of "bricks" of explosive sandwiched between two metal plates. The plates are arranged in such a way as to move sideways rapidly when the explosive detonates. This will force an incoming kinetic energy penetrator or shaped charge jet to cut through more armour than the thickness of the plating itself, since "new" plating is constantly fed into the penetrating body. A kinetic energy penetrator will also be subjected to powerful sideways forces, which might be large enough to cut the rod into two or more pieces. This will significantly reduce the penetrating capabilities of the penetrator, since the penetrating force will be dissipated over a larger volume of armour. Newer KE penetrators like the US M829A3, were "driven by the need to counter KE-effective explosive reactive armor (ERA)".Relikt was designed by the Russian army in response to the new developments. Relikt is the 3rd generation Russian ERA, and is claimed to be twice as effective as Kontakt-5. It can be installed on T-72B and T-90 tanks and was adopted in 2006. As of 2013, only the T-72BM 'Rogatka' introduced in 2006 has Relikt ERA. The Russian Army T-72B3M main battle tank incorporates Relikt. Developed by NII Stali, Relikt utilizes a completely new composition of explosives to achieve dynamics protection. Unlike Kontakt-5, it works equally reliably against both low-velocity and high-velocity missiles, doubling protection against shaped charges and increasing anti-tank guided missile protection by 50 percent. Relikt defends against tandem warheads and reduces penetration of APFSDS rounds by over 50 percent.Kontakt-5 armour is employed by Russia, Ukraine, India (T90-S) and Serbia (on M-84AS MBT), among others. Ideas have been drawn up for a new type of ERA called Kaktus, which has been developed but has yet to be deployed.Malachit - the latest generation (4th) Russian explosive reactive armor.
