About the Design Features of Modular Hunting Rifle

Abstract

The possibility of using the modular rifled hunting weapon cartridges with different characteristics is explored. For the selected cartridges the strength calculations of barrels are carried out with account of the fact that the trunks must have the same housing sizes within fixing. Restrictions on weapons imposed by the Federal law “On weapons” are given. The geometry of trunks is confirmed by graphs of strength calculation for shafts of various calibers. The ways of fastening the barrels to the receiver are determined. The conclusion on the necessity of carrying out the relevant calculations is made. The paper outlines a simplified diagram of the barrel mounting with the V-node, and the forces acting on the wedge shot. Difficulties that accompanied the development of hunting weapons series “Saiga” are analyzed. The important cycles of automatic operation are identified. The characteristics of reliable operation of feed mechanisms are determined. The drawbacks of plastic casings are described. Thus, the analysis of the specifics of the design of hunting weapons series “Saiga” will be considered during the research and subsequent development of the modular design of hunting weapons. Specific studies are outlined which are necessary for further work in creating a modular machine for the use of rifled and smooth barrels of different caliber.
