FEATURES OF THE STRUCTURE, CALCULATION AND OPERATION OF HYDROBALL TRAP

Abstract

Scientific progress and technological development help to constantly improve forensic technical devices
and methods, which allows criminologists to more effectively conduct investigations of criminal offenses and provide
court practice with reliable evidence. In this context, the problem raised in the aspect of substantiating the design of
the hydroball interceptor and its components according to the "price – quality" criterion, the development of analytical
bases for the calculation of the main structural parameters of the hydroball interceptor for expert studies during control
firings of weapons becomes relevant. Methodology. The reliability of the obtained results and conclusions is ensured by
the use of general scientific (empirical and theoretical) and special research methods. Thus, in particular, scientific and
informational sources were characterized by the subject of the study using general scientific research methods (analysis,
synthesis, generalization), and the level of sufficiency of profile information in them for the realization of the set goal was
clarified. With the help of analytical and empirical research methods, the constructive parameters of the proposed means
were determined. The systematic approach to conducting research ensured its comprehensive nature and allowed to
combine separate research results (according to the methodology of weapons research) into a single whole. The scientific
novelty of this article lies in the further development of promising directions for the development of innovative special
technical equipment (water bullet interceptors) for conducting forensic investigations of weapons during the analysis of
the investigated objects. The analytical dependence of the calculation of the length of the hydroball trap chamber length
is proposed and the concept of the effective ball extraction unit is substantiated. Results obtained. It was found that
in Ukraine, a promising solution, taking into account the "price – quality" problem, is the use of horizontal or vertical
hydroball traps. The analytical dependence of the calculation of the main structural parameters of special structures
of technical equipment for carrying out weapons research in the case of preparation and appointment of forensic
examinations within the framework of the investigation of criminal offenses is proposed. Features of the practical use of
the proposed innovative special technical equipment for weapons research are revealed.
