Modern telecommunications technologies make it possible to build communication networks that are many times greater in capacity than communication networks built on analog communication equipment. But, as you know, there is not always only «winwin », something, but you have to «sacrifice». Thus, in modern communication networks, a properly constructed synchronization system is required, the basis of which should be a primary reference oscillator, a technological equipment control system is required, the development of new communication documents is required, and much more related to the use of SDH and PDH telecommunication technologies.For this reason, newly constructed communication networks require careful testing and multi-level monitoring using expensive measuring equipment before putting them into operation. This article is devoted to some of these measurements and the problems associated with these processes.

Annotation:

This article presents a method for constructing a model of coplanar two-pulse high-speed collision avoidance maneuvers. To perform an evasive maneuver the characteristic speed has been determined to ensure the transition of the spacecraft from a given initial point of a circular orbit to a given end point of the same orbit. Carrying out the appropriate maneuver to fly around dangerous areas is formed on the basis of an analytical solution. The presented analytical support allows you to quickly and zones were carried out along an elliptical trajectory. Constructing an elliptical flyby orbit comes down to finding the shape of an ellipse that intersects the initial orbit in two ways. Convenient for experimenting with planning orbital evasion maneuvers, it allows you to construct schemes for orbital evasion maneuvers. The permissible limits of the parameters of the flyby orbits are indicated. The method allows you to determine the nearest suitable moments of time for the beginning and end of the application of the pulse.

The article is devoted to the problem of increasing the effectiveness of protection of subsonic and supersonic air transport vehicles (ATVs) from the rear hemisphere from guided missile weapons. The variants of active protection of ATVs at large and small angles of inclination of the line of sight are considered. An unmanned aerial vehicle with a solid fuel jet engine and gas-dynamic control is proposed as the main means of active protection of ATVs. Technical solutions of means of ensuring the protection of air vehicles from the rear hemisphere are given. It is established that the defense of low-speed and high-speed aircraft during their attack from the rear hemisphere has significant differences and can be provided by the use of an unmanned aerial vehicle equipped with a solid fuel rocket engine (SFRE) with the necessary characteristics.

Annotation:

The article highlights the problem of ensuring the creation of an automated system for controlling the combat operations of units at the tactical level, taking into account the variety of all possible factors of the combat situation, the conditions for the use of weapons and individual actions of military personnel. To solve this problem, various expert systems for developing rational tactical actions based on fuzzy set theory have been considered, which will allow for high dimensionality and all uncertainties, as well as significantly increase the efficiency and validity of decision-making. These systems, which allow you to interface thought processes with external information flows, in the present and future can be implemented both on the basis of today's traditional «tablets» and on the screens of helmet masks of military equipment, as well as using compact scanning devices in military helmets.

Annotation:

Some specific features of terrorism in the XXIst century are considered. It is noted that the availability of significant financial and technical resources for terrorists, as well as the commercialization of space, make a threat of «space terrorism», which means the destruction or damage of spacecraft in outer space. The techniques used to protect against meteorites and space debris can be used for shielding. The optical elements of spacecraft are the most vulnerable to mechanical damage, since widely used protective screens are opaque to optical radiation. The designs and technologies that afford protection or minimize the damage are given. The advantages and disadvantages are considered. Recommendations are given on the expediency of their use depending on the aperture of optical elements and operating spectral ranges.

Annotation:

The article considers the problem of the need to clarify the source data system (SID) for assessing the vulnerability of manpower when exposed to a fragmentation field, without which it is impossible to solve the problem of increasing the effectiveness of fragmentation anti-personnel mines. It is shown that the formation of the field of destruction of combat units of anti-personnel mines made using small-sized high-strength striking elements (such as shot) provides multiple effects on the target with the implementation of an additive mechanism of destruction by summing the effects of a group of striking elements is realized. It is proposed, in addition to the «medical» criterion for the defeat of manpower to additionally introduce the concept of a «combat» criterion for its defeat, regulating the delay time of its loss of combat capability after the received impact, taking into account the conditions of the operational and tactical situation.

New types of equipment are actively used today to suppress gangs. Including actively used unmanned aerial vehicles (UAVs). However, the use of UAVs alone does not always provide the necessary advantage over the enemy. Practice shows that only joint actions of UAV and artillery operators allow achieving synergy in solving combat missions. The article briefly examines the issues of using motor vehicles by troops. The authors consider the prerequisites for the necessary improvement of military motor vehicles. Also in the article, the authors consider the possibility of mounting the Lilia automatic mortar system, developed by the authors based on requests from law enforcement officers, on a vehicle chassis. In addition, the article briefly examines general issues regarding the creation of innovative transport systems.

An overview is given and directions of modern developments of laser weapons are shown. A protective device is presented that forms light in the form of a light curtain with mixed RGB laser radiation and is designed to disrupt the orientation of an enemy drone and possible damage (blinding) of its optoelectronic surveillance system (camera). Structural and energy analysis of laser systems «anticopter» was carried out. Conclusions are given based on the results of energy analysis of illumination and possible damage to the drone camera matrix by an experimental sample of a protective laser device. Structural and technical requirements to laser radiation source are defined. The example of a powerful laser of the YLPP series manufactured by NTO «IRE-Polyus» shows the optimal layout of a wearable laser of the «anti-drone» system with a fiber output of radiation and structurally made in the form of separate control and power units and a radiating head that can be quickly directed to the target.

Annotation:

The patterns of changes in excess pressure in the air shock wave front in the near zone of the upper hemisphere when an explosive charge is detonated in an explosion protection device have been studied. It has been established that the explosion protection device does not change the propagation profile of the air shock wave, in comparison with the profile characteristic of detonating an open explosive charge of the same mass. In this case, there are no clearly expressed gradients in the amplitudes of excess pressure in the front of the air shock wave, due to the layout and design characteristics of the explosion protection device. The use of an explosion protection device makes it possible to reduce the level of excess pressure in the air shock wave front by up to 20 times in the near zone from an explosive charge in comparison with detonation of an open explosive charge of the same mass.

Annotation:

The reliability and survivability of special-purpose equipment increases with a decrease in the probability of failure of the functional coating in terms of strength. Multilayer functional coating is characterized by high homogeneity and low defectiveness. To ensure the uniformity of a multilayer functional coating, a supersonic spraying method with a multi-jet supply of atomizing gas is recommended. An experimental study showed that an increase in the number of single layers and a decrease in their thickness contributes to an increase in the strength of a multilayer functional coating when separated from the base and in tension. A large-scale effect has been established, which consists in the influence of the layered structure on the strength of the coating samples. Layer-by-layer spraying of a functional coating of 3–7 single layers is recommended, which ensures its acceptable strength with high process productivity.

Annotation:

Article is devoted to the study of the composition of the air environment of the inhabited compartments of light armored vehicles on the example of the 2S1 self-propelled howitzer, the «Carnation» cipher in the conditions of using an incendiary mixture of napalm type. Napalm was applied in a concentration considered as combat to the surface of the body of a self-propelled howitzer and to the area of the air intakes of the filter ventilation unit (FVU). As a result of the conducted studies, a significant increase in temperature on the inner surface of the armor and a slight decrease in the oxygen content in the inhabited compartment were found. Due to the ignition of rags in the control room and thermal destruction of paint, an increase in the concentration of CO, CO2 and hydrocarbons was recorded on the inner surface of the armor. There was a pronounced irritating effect of the conjunctiva of the eyes and mucous membranes of the upper respiratory tract. The process of burning napalm caused the subsequent malfunction of the FVU.

Annotation:

The question of peculiarities of the destruction of shell-less explosive objects using impactacting powder destroyers is considered. It is shown that most of the existing domestic and foreign impact destroyers contain explosive charges that can cause complete detonation of shell-less explosive objects or explosive objects with thin-walled shells. The design of the impact powder destroyer is proposed, the operability of which has been confirmed in range conditions during the destruction of shell-less explosive objects containing 0,2...0,4 kg of trinitrotoluene charges and EDP electric detonators. The design of the impact powder destroyer proposed by the authors should be introduced into the practice of specialists of engineering departments of law enforcement agencies.

Annotation:

The article analyzes the processes of obtaining construction foam based on various foam stabilization mechanisms and technical solutions for its production. The use of micro- and macro-sized fiber fibers is proposed in order to increase crack resistance and increase the multiplicity of construction foam. The micro–size of the fiber will break up sol particles and thereby increase the multiplicity of the construction foam, and the macro-size will stabilize the foam film and increase the crack resistance of the foam material. A new technical solution for obtaining construction foam on a developed device with foamcutting elements located at an angle to the walls of the foam cartridge is proposed, which will allow to obtain high-quality foam and uniform mixing of fiber or other additives with foam. The characteristics of the construction foam reinforced with fibroblast obtained using a new technical solution are given.

The article is dedicated to the 75th anniversary of one of the founders of the theory of habitability of objects of military equipment and wound ballistics, Doctor of Medical Sciences, Professor Stanislav Mikhailovich Logatkin. Under the leadership of S.M. Logatkin solved the problems of studying the patterns of the flow of powder gases into the fighting compartments of armored military equipment, worked out ventilation and purge modes of the barrel bore, and established maximum permissible concentrations of powder gases for various firing conditions. Fundamental research was carried out to develop standards for fire regimes based on an assessment of harmful factors in the working environment, to study the health status of artillery crew numbers in various climatic regions, as well as to substantiate the principles of normalizing the armor impact of striking elements when the body armor is not penetrated.

Annotation:

The article is devoted to the study of the problem of creating safe conditions of military service in the workplaces of servicemen of the Armed Forces of the Russian Federation. The current security management system of the military service is currently unable to ensure the creation of declared safe conditions for military work at every workplace. Moreover, a long-term stay of a serviceman under the influence of harmful and (or) dangerous factors of military service with a high risk of damage to health, except in cases of death or injury with labor loss, is not a violation of domestic legislation. In our opinion, the system of prohibitive measures is not sufficiently developed: preference is given to the development of a system for providing military personnel with social benefits and compensation in connection with military service in special conditions.
