Sound suppressors for small arms with annular expansion chamber
Journal Title: Технічна механіка, Техническая механика, Technical Mechanics - Year 2014, Vol 3, Issue 3
Abstract
The paper deals with information about sound suppressors for small arms when an annular expansion chamber and two-point mounting attached to the firearm barrel are used. Those patented designs are examined, as from 1910, when the patent for a sound suppressor with such chief essential features was granted. Designs of patented sound suppressors and mechanisms of their operations presented by the authors of inventions are de-scribed. The most-used designs of sound suppressors with an annular expansion chamber of the Reflex Suppres-sors type (Finland) are considered. The authors presented their designs of sound suppressors with an annular expansion chamber. The disadvantages of such designs are reported, including the authors’ designs. Information sources, in which data about the special features of thermogasdynamic processes in sound suppressors were published, are listed. In accordance with the results of their analyses variations needed for the sound suppressor design are validated to improve its characteristics. The sound suppressor design, in which outlined variations were realized, is described and the results of full-scale tests are presented. The conclusion about rationality of using the authors’ sound suppressors is made, in particular for high-power ammunition of firearms.
