Abstract:

The model for external ballistics calculation in a full three-dimensional formulation in the material point dynamics approximation with allowance for side wind is described. Errors, determining the probability of hitting the target, are considered. Mathematical simulation of the grenade impact at a target is carried out by statistical tests with external conditions of firing variation. Estimations of tank frontal projection hit probability for different firing modes of grenade launcher are presented. The fundamental possibility of realization of wind drift compensation for unguided munitions with auto-regulated engine is shown. Significant increase of the grenade hit probability when using a jet engine with the thrust characteristics auto-regulation system in conditions of aiming accuracy and weapon orientation increasing is theoretically proved.

Abstract:

A generalized motion’s mathematical model of an asymmetric uncontrolled rotating body (bullet) in air in three-dimensional space with resistance forces given in the form of approximating functions is developed. A mathematical scheme for the bullet’s motion on a trajectory is described and an aerodynamic design model for determining the forces acting on the body from the software product ANSYS CFX is compiled. Verification of the theoretical drag force, obtained from the ANSYS CFX with the firing tables was carried out, determined deviations from practical values. The external ballistics for the 7H6 bullet was calculated in accordance with the developed mathematical model under certain initial conditions for the bullet’s location in the barrel and the relative errors of the main trajectory parameters were analyzed. Directions of further research and the main results of the work are determined.

Content of computer modeling of process of pulse loading of the helmet and the simulator of the head by the shock wave of explosion for forecasting of weight of the injury is shown. At the same time the way of the assessment of injury prevention of the helmet which was earlier successfully applied to the assessment of shock resistance of the helmet on condition of lack of its perforation is implemented by the striking ammunition element. As criteria of injury prevention of the helmet it is offered to use comparison of curves of the overload and intracavitary pressure of the ballistic simulator of the head equipped with the regular and perspective helmet.

Abstract:

A new method for the rapid compilation of differential equations of motion of mechanical systems of an anthropomorphic structure with hinges and links of variable length is developed. They are close to reality due to modeling in three-dimensional space and are suitable for immediate practical implementation, unlike two-dimensional models that can not be used to create real samples. The proposed model can be used to create military exoskeletons, anthropomorphic robots, and to study the human musculoskeletal system.

Using the error function erf(x), it was proposed to automatize the computational procedure for estimating a hit-probability in a shooting-target. Using Microsoft Excel and Matlab/ Octave software products an algorithm and program code for calculating a hit probability are developed. A feature of the hit-probability calculating is that the target is divided into a set of rectangles. The initial data for the program are: coordinates of the rectangle, parameters of the dispersion ellipse and coordinates of the point of impact (POI). The example of the hit-probability estimation for targets № 5, № 6 is given. It presents the transformation of the probability of hit when the coordinates of the POI change. An assessment of hit-probability during a shooter salvo attack is shown.

It is shown that the low level of consistency, which was accompanied by large-scale reform of society in the 90's, and survived in our time when the solution of a number of political, economic, industrial, social tasks, which confirms the range of existing well-known problems. It should be noted that the presence of a variety of problems characterize the low level of systemic changes, and their absence indicates the system solution of problems.

The article is devoted to the assessment of the prospects of modernization of the insurance Fund documentation for weapons and military equipment in the direction of the introduction of new approaches and modern information technologies. Historically, the creation of the insurance Fund was based on the method of optical microfilming of paper originals. However, the micrographic technology of creation of the insurance Fund does not fully meet the requirements for modern systems of long-term storage of information resources, which involves its gradual replacement with electron-micrographic and digital technologies. The increase in the number of technical documentation, initially created in electronic form, entails the need to bookmark it in the insurance Fund on electronic media. The transition of the insurance Fund system to the modern organizational and technological digital base will provide a multiple increase in the efficiency of the system and improve the quality of the creation of insurance information.

Abstract. Noise is one of the leading places among the harmful physical factors in the Armed Forces of the Russian Federation. Features noise resulting from the operation of weapons and military equipment is its high intensity, intermittent nature, the presence in the spectrum of infrasonic frequencies, long duration. The soldiers in the exercise of his professional duties in the process of training of action are subjected to irregular exposure to noise and infrasound, which increases the overall morbidity and creates high risks of development of occupational diseases. The adverse acoustic environment at workplaces soldiers require preventive measures. The noise resulting from the operation of military equipment, often creates discomfort for the population and a threat to the environment.

Abstract:

Thanks to the discovery of radioactivity phenomenon, there were made breakthroughs in many spheres of human activity, such as the field of medicine, various industries, especially in the energy sector. However, the more intensively this phenomenon was used in the products of human labor, the more serious was the danger of radioactive contamination of the environment. The main environmental problem in St. Petersburg and the Leningrad region, which needs to be solved now, is to reduce the level of man-made pollution, taking into account Russia's international obligations. To solve this problem is impossible only with the help of environmental measures as a significant part of the region's enterprises use obsolete equipment and technology. In this article, the authors assess the internal exposure of the population on the example of radionuclides in the human body with air and food.
