Abstract
The purpose of the work was to experimentally research and analyze the effect of the proposed modifications of a pneumatic bullet on the accuracy parameters of the shooting system with a subsonic initial speed. The study introduces variants of modernization of a bullet with a flat head part for pneumatic weapons, describes the external ballistic experiments carried out on the ballistic track of the Department of Dynamics and Flight Control of Rockets and Spacecraft of Bauman Moscow State Technical University, and theoretically substantiates the physics of the interaction between a bullet and the air, which became possible after analyzing the results of shooting. The obtained correlation between scattering characteristics of unguided aircraft and the type of modification of their aerodynamic shape is described. On the basis of the data obtained, modifications of the bullet shape were determined, leading not only to a decrease in aerodynamic drag, but also to a certain decrease in dispersion during shooting.
