Additional arguments are given in favor of underestimating the significance of the system methodology, the systems approach to scientific research and research in the field of safety, weak efficiency of the processes associated with the preparation of gunsmith designers who create individual automatic weapons. It has been proven that there is only one powder engine in the Kalashnikov machine gun, but because to define the «side gas engine» it is necessary to use the well-known term «side gas device», which refers to the transmission mechanism, that is, to the transmission elements. It is necessary to focus on the driving forces of automation, the term «motors of automation» excludes from training courses.

Abstract: In order to ensure the electromagnetic compatibility of radio electronic equipment (RES) satellite communications (SPS), it is necessary to eliminate interference, including those resulting from exceeding the allowed radiation power of SPS earth stations (S). To solve the problem of determining the sources of interfering radio emissions, there are ground-based radio monitoring complexes (CRM), the most important characteristic of which is the noise quality factor of the receiving systems, which allows to determine the quality of reception of radio signals in the interests of their further processing. The article proposes a method for determining the requirements for this characteristic when designing ground-based CRMs, taking into account their spatial location, the impact on radio receivers (RPRU) of unintentional interference with various parameters, energy characteristics of radio electronic facilities, and threshold signal-to-noise ratios when receiving signals.

Аннотация:

Forcing diesel engines at an average effective pressure and at the nominal crankshaft rotation speed leads to a significant decrease in their mass and size parameters of the internal combustion engine with a simultaneous increase in air temperature, absolute and especially relative dimensions of its coolers. The use of two-stage pressurization significantly complicates the design of the air supply system. One of the effective ways to reduce the charge air temperature is evaporative cooling. However, the gain in power and efficiency of the internal combustion engine decreases due to the need to compress the formed water vapor and additional losses due to disruption of the air flow kinematics, the need to transport droplets and water films along the surfaces of the centrifugal compressor flow part.

Аннотация:

The perimeter of the guarded object is the first boundary of its protection, and its safety substantially depends on the quality of the established systems of protection. It has been proved that the integrity and integrity of property will depend not only on the speed of the security service, but also on the universality and quality of established perimeter security systems. This article is dedicated to the description of work, special features of use, installation and to the analysis of the positive and negative properties of different types of technical equipment for guarantee safety of the perimeter of the guarded object. It is emphasized that perimeter security can be carried out both with physical barriers and with the use of modern security alarm systems. It is concluded that at the moment it is impossible to distinguish a universal system of protection, and it is necessary to analyze a large amount of information: the possibility of highlighting the exclusion strip, terrain, the design and material of the fence, vegetation, the presence of a close railways or highways migratory paths of animals and birds, as well as much more. It is noted, however, that at the moment it is impossible to distinguish a universal system of perimeter protection.

The article argues the urgency of creating special risk insurance funds and substantiating the norms of special security of arms. It is noted that the correct methods for substantiating the norms of special security for the RF Armed Forces have not been developed. The article proposes principles for assessing the standards of special security, using the theory of risk insurance, it is shown that the task of determining the norms of special safety and the task of determining the volume of a special risk insurance fund are the direct and inverse problems of the risk insurance equation. For special risk assessments, it is proposed to take into account non-applied and un-prevented damage resulting from an accident with ammunition armaments, military and special equipment. Due to the fact that there is uncertainty at the accident site, for its disclosure, the main stages of the passage scheme are considered, in which the sample is in groups with similar or other weapon that are potentially damaged as a result of the accident. Next, the mathematical expectation of the possible consequences of the accident is determined, taking into account the length of time the sample is at a particular stage of the passage scheme.

One of the methods of justification the expedience of new sample development is suggested in this article — the method of estimation for the leap possibility in the development of weapon subsystem according to evaluation of system quantitative and qualitative indicators. The method was created in order to reduce subjective components of research and to reach some unambiguity for recommendations during the deciding of new WMST sample creation.

Аннотация:

At all stages of the life cycle of artillery ammunition, the main forms of technical control of their condition and quality assessment are tests. The implementation of relevant test programs requires substantial expenditures of material and time resources. Since the organization of any type of testing is carried out based on a sampling approach, one of the promising ways to reduce these costs is to reduce the number of munitions included in the statistical sampling during testing. The article is devoted to the development of methodological provisions for such a reduction while maintaining the representativeness of the sample. Ensuring the required accuracy and reliability of statistical evaluations is achieved by the fact that, along with the directly obtained test results, additional information is taken into account on the possible values of the technical characteristics of the properties of ammunition. Integration of all available information is based on the entropy approach.

The complex provides the formation of overloads pulse with the broad range of amplitudes and FWHM. The maximum pulse parameters achieved: peak overload — 70000 g, FWHM — 0,6 ms. The overload regime required for specific tests is formed by selecting the velocity of the projectile-container and (or) the design of the crash. The testing method of operation modes of electronic devices during action of an overload is developed. Results of tests of power supplies and electronic assemblies on resistance to overloads to 70000 g are given.

Аннотация:

The results of experimental studies of the range of visibility in aerosol are presented. We considered two types of aerosol-formed by the combustion of powder and the evaporation of glycol solution in water. Studies were carried out by the method of «disappearance of the object». An appropriate experimental setup was used to carry out the research. As a result, the dependences of the aerosol mass concentration on optical density D and the visibility range L on optical density D and mass concentration Q of aerosol are obtained. It is shown that the object of protection in the aerosol when illuminated from behind or from the side is observed further than when illuminated by the observer. The obtained ratios L = f (Q), Q = f (D), or L = f (D) will be useful in testing aerosol means non-lethal effects on violators, as well as in mathematical modeling of the formulation of optically opaque aerosol screens in protected areas.

The object of the study was bone conduction of sound as one of the ways of sound delivery to the inner ear. The mechanisms of sound transmission by air and bone tissue are described. The possibilities of using bone conduction to obtain sound information from the outside in various fields (power structures, medicine, sports, recreation) are considered. The use of a device based on bone conduction is a reliable channel for obtaining sound information from the environment, which means that it expands the capabilities of a person. The method of bone conduction study for subjective evaluation of acoustic efficiency of head, thoracic and abdominal personal protective equipment against high-intensity and low-frequency noise is described. Bone conduction headsets should be used to improve PPE, which will allow to maintain speech contact at the optimal level in conditions of high-intensity and low-frequency noise.
