Abstract:

The article considers problems of relation between an above-ground height of a charge detonation and increase of the explosive effect on the explosion outside zone on the ground. Charge optimal heights allowing obtaining 60% higher pressure than that found by numerical simulation at the on-ground explosion. Numerical calculation data have been verified experimentally. .Engineering formulae calculating maximum pressure values depending on the height of a charge suspension have been given.

Abstract:

Super-wideband electromagnetic impulses as a damage factor capable to disable model communication and control systems have been studied not well enough. By reason of lack of theoretical approaches to that problem and shortage of applied models an assessment of super-wideband electromagnetic impulses effect can be obtained only experimentally.

Abstract:

Station keeping of deep water equipment has always been a problem. To solve it, it is necessary to introduce innovations into developing navigation systems. Although, even those innovations cannot allow spotting a site of an underwater device reliably. A possibility of an accurate definition of an underwater device location is provided by new technology. One of such methods is presented in this article.

Abstract:

Blasts of various vehicles fuel tanks leads to their failure and toll on human lives. Using tanks with neutral gasses as a blast protection tool is complicated with complex service, necessity to fill the tanks etc. Blast protection systems based on high-porous mediums do not have those shortcomings.
