Abstract:

All calculations of objects on resistance to mechanical impact of explosion are traditionally carried out for air shock wave. In place so in reality the explosive wave front is expanded. In the article the method of estimation of the average loadings created by a real explosive wave at diffraction on a standard barrier is offered. Its reliability is demonstrated on the relevant experimental data. It is shown that the inclusion of the extended front of the explosive wave allows for a given regulatory level of impact on Δp+ 2...6 times to reduce the estimated level of maximum loads and accelerations of the object in comparison with calculations based on the traditional idea of a shock wave. It is offered to consider the revealed effect at design of means of protection against explosion.

Abstract:

At present, there is a tendency to use unauthorized technical means, using a hidden transmission of information. Ensuring the stealth transmission is achieved through the use of signals with a small power spectral density and a wide spectrum. Such signals with a limited duration have a spectrum of unlimited length. This leads to the possibility of using them to hide the radiation of means of secretly extracting information and, accordingly, to complicate the search for radio channels of these means. The existing methods of detecting private information transmission are mainly aimed at searching for narrowband signals or broadband ones that require a priori fame of their parameters. The presented technique is based on a new method for detecting unauthorized electronic devices using broadband signals for information transmission as information. A distinctive feature of the technique is the detection of broadband signals, as well as the moments of their operation in a predetermined frequency range in the absence of preliminary data on their parameters due to the analysis of the interference environment.

Abstract:

A stochastic model for predicting the technical condition of propellant powder charges during long-term storage is proposed. The integral criterion of evaluation of technical condition of propellants propellants during prolonged storage is adopted, the supply of chemical resistance. The change in the technical state of the propellant charge is a stochastic dynamic system described by a three-dimensional vector of a random stochastic branching process with a finite number of types of «particles». The obtained system of differential equations is solved with the help of generating functions. Performance and reliability stochastic forecasting model of the technical condition of missile charges, evaluated using the data STK artillery shots index 3ВОФ5.

In recent years, Russia has paid great attention to the creation of a hydroacoustic system. Improvement of the new digital technologies considered in this work and finding broad application in hydroakoustic systems of communication, management, navigation is advisable. To reduce the number of errors due to the multipath nature of the propagation of hydroacoustic signals, as well as the presence of interference in the hydroacoustic channels, it is necessary to use the digital signals applying difficult methods of processing, for example, of MIMO-OFDM.

Abstract:

This article presents the results of full-scale tests of a technical device based on a heterogeneous two-phase medium to suppress the damaging effects of underwater explosions. The fundamental possibility of mitigation of underwater shock wave, formed after detonation of the explosive charge, by two-phase heterogeneous medium layer was shown. Prototypes of technical devices for underwater explosion mitigation were made of thin shells filled with two-phase organic and nonorganic material of different thickness. To determine the effectiveness of the technical means for suppressing the damaging factors of the underwater explosion, the detonations of 0,8 kg of ammonite 6 GV were carried out in a closed reservoir at a depth of 2,8 meters. It was established experimentally, that the underwater shock wave amplitude was the most effectively reduced by technical device based on organic material with 18 cm thickness. Shock wave overpressure was reduced more than 25 times.

The article introduces a new device that allows to protect the process of object monitoring from their unauthorized replacement. The principle of operation of the device consists in sequential interrogation of the sensors connected to it, which allows to determine the operation of the sensor, as well as the fact of the sensor failure. Due to the cryptographic closing of the control message, the imitation protection function is implemented. The device can be used to improve the security of objects, including in conditions of terrorist activity.

The article examines some areas of rational allocation of allocations allocated for the development of the troops of radiation, chemical and biological protection. Considering different scenarios for providing the Armed Forces of the Russian Federation with weapons and means of radiation, chemical and biological protection, taking into account possible financing options, the author identifies the three most characteristic ones associated with the choice of the «revolutionary» or «evolutionary» ways of developing the weapons system of the troops. Based on these scenarios, it is proposed to develop three basic variants of proposals for the draft state armament program for 2018-2027 regarding the development of radiation, chemical and biological defense troops.

Abstract:

It is proved that at the present stage of the development of automatic weapons, first of all, combat vehicles should be excluded the use of the terms «automatic Engines», «Side gas engine» from the weapon practice, since they do not correspond to the physics of the processes occurring in the automatic shooting, and make errors in the educational, scientific and design processes. At the same time, modern systems of computer-aided design of weapons require a clear formalization of all its elements and do not allow their unreasonable interpretation by various participants in the process of creating weapons. This is fundamentally important in the formation of the scientific base corresponding to the tasks of creating «weapons of the future». In addition, the paper shows that the systemic errors made in the development of the law «on weapons» have led to serious difficulties in the educational and scientific processes of weapon departments of the country, to the impossibility of their use of military weapons and ammunition, which adversely affects the Military security of the country.

Abstract:

Noise and infrasound are harmful production factor according to its frequency, they occupy the leading place in the national economy and the Armed forces. When evaluating working conditions the noise levels and infrasound at working places military personnel meet the hazardous classes that creates high risks of development of occupational diseases. Noise exposure leads to a reduction of military-professional health and increase morbidity. In the current regulations of the military medical services noise and infrasound are not identified as a harmful factor, and therefore not fully developed the issues of professional selection and medical examination of noise pathology. An important place in the system of prevention of harmful action of noise is given to PPE. Their absence and the low efficiency of acoustic threaten the safety of military personnel. The existing system of measures to combat the harmful effect of noise in the Armed forces requires revision.
