Annotation:

This article presents a methodology for assessing the military-economic efficiency of resource provision of military consumers outside the Russian Federation using foreign logistics potential. The relevance of the development of such a technique is connected with the fact that in the current geopolitical confrontation of Russia it is important to make the most effective use of the available military contingents to protect its interests in this confrontation. One of the types of such contingents are groups of troops (forces) outside Russia, the functioning of which, in turn, depends on the quality of use of foreign logistics potential. It is to assess the level of realization of this potential that the proposed methodology will be designed. Тhis technique has an applied orientation and allows to solve a number of problems at the present stage of development of resource support of troops (forces) outside Russia, in terms of the assessment and possible options for improving its military and economic efficiency.

Article is devoted to questions of features of external ballistics of bodies equipped with flexible link (cord) are considered. Systems of equations of motion of bodies (grenades) are obtained for two possible versions of cord throwing devices: cord throwing device with coil with cord in grenade (mobile coil), or cord throwing device with coil in launcher (fixed coil). The article concluded that version grenade with mobail coil has advantage because the cord does not have an air resistance force. Based on the analysis of the results of the carried out calculations, the regularities of movement of bodies equipped with a flexible link, used in the design of linear devices, were revealed.

Annotation:

The paper presents a scientific and methodological apparatus for evaluating the ricochet of conventional weapons when they are exposed to objects-targets with different surface geometries of their protective structures or protective devices. The theory is based on the consideration of the energy interaction of the kinetic energy of movement of conventional weapons and the potential energy of resistance to penetration of the barrier’s structural material in the form of protective structures or protective devices of the target object under fire at various angles of approach relative to the plane of their surfaces. The proposed scientific and methodological apparatus is quite suitable for taking into account the possible ricochet of conventional weapons when assessing the security and survivability of military and civil infrastructure, as well as justifying the calculated degrees of protection of special fortifications in the conditions of calculated impact on them by enemy weapons.

Annotation:

The normal and oblique interaction of long (20 gauges) steel isotropic cylindrical impactors with an orthotropic composite plate in the range of impact speeds up to 2000 m / s is investigated. The problem is solved numerically by the finite element method in a three-dimensional formulation within the framework of the phenomenological approach of continuum mechanics using the author’s software package. The behavior of the projectile material is described by an elastoplastic medium; an elastic-brittle model that takes into account the anisotropy of its elastic and strength properties describes the behavior of the barrier material. As a condition for the strength of the anisotropic composite, the fourth-degree tensor-polynomial criterion is used. The effect of the angle of nutation on the destruction of the plate and the behavior of the impactor in the process of introduction is investigated. It is shown that the presence of a nutation angle during the interaction of long impactors leads to a loss of stability of the impactor and has a significant effect on the development of fracture in the barrier.

The task of reducing the service life of individual means of armor protection, due to the relatively high cost of their manufacture, is very relevant. Despite this, currently there are no methods that would allow to conduct the necessary research and assign storage periods for bulletproof vests. For elements of an artillery shot, namely for a propellant charge made of gunpowder, there are ways to extend their service life. The device of modern bulletproof vests is briefly considered, where special attention is paid to elements made of fabrics based on paraaramide threads, similar in composition to gunpowder.

as an indicator of evaluating the effectiveness of protective properties of individual armor protection are substantiated. To determine the possibility of obtaining specific technical parameters of the interaction of the striking element with the protective composition, this process was visualized using a complex of high-speed video shooting. This made it possible to analyze the impact of the striker on the ceramic and fabric armor panels and compare the maximum height of the local back deformation of the panel, formed as a result of local destruction and displacement of the protective structure, with the thickness of the climate-damping support (CAP). A number of indicators were obtained that can be used as parameters for assessing the condition of samples of armor panels of various compositions in the aspect of assessing the level of impact of the armor. As one of these indicators, we can recommend to consider the value of the impulse of the out-of-the-barrier protrusion.

Performing piece unloading and loading of pipes by loading teams at the operational stages of field trunk pipelines (FTP) is currently a very laborious operation and requires a large number of personnel. Reducing the laboriousness of loading and unloading operations during theassembly and disassembly of the FMP is the most important task of improving the operating efficiency, so the issues of complex mechanization should be considered from the standpoint of the reduction of normative time indicators. The results of experiments allow us to explain the duration of the operation cycles of unloading and the layout of the pipes withthe manual installation teams (MIT), as well as the manual dismantlingteams (MDT) that gather and load pipes into the car body using tick-borne capture of the crane.
