Influence of the Structure of N-paraffins on the Detonation Properties of Plastic

The experimental methods for styding detonation properties of paraffin’s based substance is proposed. The schemes of using experimental equipments are shown. The methods approbation for example С18Н38 and С22Н46 were made. It is shown that the proposed method can be used to assess the ability of the detonation of explosives.

Definition of Position of the Victim at the Moment of a Shot on Stains of Splashes of the Blood Which Have Been Beaten Out by a Bullet

This paper investigates the error in the determination of the victim the moment of firing by spots of blood spatter. It is shown that the position of the victim in a horizontal plane can be determined in some cases with an accuracy of ± 2.5 cm.

The Physical Method of Assessing the State of the Connective Tissue of its Restructuring in the Field of Fire Trail

The question about the possibility of time determining of the appearance of defect after the contact of fired missile with the cover layer of the skin is examined. The hypothesis about the redistribution of a quantity of molecules of low-molecular solvent in the zone of damage due to the confluence of specific defects – the super-vacancies, which facilitate a change in the diffusion coefficient is advanced.

Definition of Quantity of Shots from Firearms – the Analysis of Existing Approaches and Theoretical Preconditions of the Solution of a Task

In article recommendations available in literature about definition of number of shots from firearms are analyzed. On the basis of the experiments carried out by the author the contentious clauses demanding additional check are allocated. The research directions, allowing to receive more reliable recommendations are offered.

Prospects for the Development of Automatic Small Arms

Presented promising developments in the field of firearms and the main trends of its development. Shows the tactical and technical characteristics of a firearm.

Problematic Issues of Forensic Study of the Basic Parts of Firearms

In the article shown that the actual task is to develop a forensic requirements and criteria which should satisfy the basic parts of firearms. Was shown that the condition of these parts should be such that they ensure the production of shot and normal interaction with other details of a particular model.

Thermal Matematical Model of the Non-detonation of the Ammunition

Mathematical model of heat through the shell of ammunition, to initiate the combustion reaction and assess the possibility of destruction of the shell to achieve the critical parameters of the detonation of the charge is submitted. Heating of a cover of an explosive is made by laser system. 

Systems of the Neutralization of Shell Ammunition Without Detonation

In this paper we present lasers with self-phase conjugation, providing the possibility of obtaining high-power radiation. Possibilities of application of multichannel solid-state laser systems for neutralization of explosives without formation of the critical sizes of zones of warming up of explosive are besides discussed.

Problem of a Choice of Methods of Collecting and Research of Products of a Shot

The article shows the promise of research products shot by scanning electron microscopy. Spectrogram of the elemental composition of particulate product shot is presented.

Research of Products of a Distant Shot by Means of a Scanning Electronic Microscope

This paper presents the results of studies using SEM product shots fired various ammunition. The elemental composition of the product shots, tripping primer composition and morphology of the deposited particles were investigated in this paper.
