Abstract:

Тhe attention is focused on increasing the importance of the system methodology in the design and construction of modern weapons as complex systems, which proves the importance of training of specialists in the arms departments, not bachelors for the needs of the defense industry and military security of the country. The unity and fundamental difference between the processes of design and construction of weapons is shown. The attention is paid to the fact that the subjects of design and construction processes in the person of the designer-armorer or design Bureau are systems, which implies the effective use of system methodology, system approach in the practice of management of creative teams. At the same time, the presence of problems in the work signals a low level of systemacity, and their absence characterizes the system management style.

Abstract:

High dynamic load in front region of air explosion wave leads to essential distortions during overpressure measurement and registration. The distortions manifest themselves in the form of high frequency oscillations on the experimental plots Δp(t) of overpressure. Often they are caused by the discrepancy of the dynamic properties of the measuring systems to the process of pressure increase ΔpS(t) in the front region of the recorded explosion wave. The article demonstrates the effect of the dynamic properties of the measuring system on the accuracy of determining the amplitude Δp+ of the pressure in the explosive wave. Based on the comparison of experimental and calculated results, it is proposed a condition for selecting a measuring system in which this effect is minimized. Also demonstrates the ability to identify on the basis of joint analysis of experienced and calculated data the dynamic error in the determination of the amplitude Δp+ waves.

Abstract:

The structure of the explosive wave front in air is analyzed. Expressions for mass velocity and pressure profiles in the front of a weak explosive wave are obtained. They well describe the change in excess pressure in the front is not only weak, but also a strong explosive wave. Comparison of these dependences shows that pressure must reach its maximum sooner than mass velocity. In other words, the «splitting» of the parameters of a gas-dynamic flow is possible within the explosive wave front. This is supported by the experimental data. The methods of experimental verification of the data obtained from theoretical inferences are proposed.

Abstract:

The article proposes criteria for assigning technical means to military measuring instruments. As the basic criteria of appointment, standardization and unification, reliability, firmness to external factors are allocated. The destination criterion avoids the attempt to expand the application of the notion of military measuring instruments to technical means that are functionally designed to use measurement results for other end uses. The criterion of standardization and unification determines the requirements for the completeness of military measurement equipment with unified and original elements. The reliability criterion defines the requirements for military measuring instruments to preserve in time the ability to perform the required functions in the specified modes and conditions of application, maintenance, storage and transportation. The criterion of resistance to external influencing factors determines the requirements for ensuring the properties of military measuring instruments to maintain the ability to perform the required functions in conditions of established types of impacts of external factors. The proposed criteria, in contrast to existing ones, make it possible to specify the procedure for assigning technical means to military measuring instruments.

Abstract:

Ensuring safe drinking water of the proper quality is an important problem in the performance of military tasks in the field in isolation from sources of guaranteed water supply. At present, the most appropriate solution is the use of filters for water purification and disinfection. The main types of individual and group water purification devices used up to the state of drinking domestic and foreign production are considered. Analysis of filtering systems (Aquamira filter tubes (USA), Katadyn flasks (Switzerland), LifeStraw filters (USA, China), etc.), which provide purification of water from natural sources, showed that water purification and disinfection in these systems is provided at the expense of membrane fibers (LifeStraw), or sorption materials with the use of disinfecting elements (Katadyn). The principle of the work of the perspective filter for purification and disinfection of water using liquefied gas for water injection is proposed.
