Development and full-scale tests of unified sound suppressors for small arms
Journal Title: Технічна механіка, Техническая механика, Technical Mechanics - Year 2014, Vol 1, Issue 1
Abstract
The paper deals with information about the authors’ works on the improvement of the firearm sound sup-pressor design and optimization of the performance. Designs of unified sound suppressors developed by the authors and the results of full-scale tests for reduc-tion in the discharge noise level using these sound suppressors are presented. Results of comparative full-scale tests of sound suppressors developed by the authors and the ASE Ultra S-series sound suppressor are reported. Data about the results of tests of the life of one of the basic sound suppressors, causes of its failure and pre-cautions taken to improve the life of this sound suppressor under extreme operation conditions are provided. The basic characteristics of unified sound suppressors developed by the authors and data about the types of the host hand firearm are presented.

Sound suppressors For small arms with elastic deformable structural members
The paper deals with information about firearms sound suppressors using elastic deformable members, sig-nificantly springs. The results of analysis of their designs are presented and three groups of sound suppressors are...
Simulation of the evolution of a droplet cloud thrown into the atmosphere as a result of an explosion of a launch vehicle with self-inflammable propellant components
The aim of this work is to develop a methodological approach to simulating the evolution of a droplet cloud (DC) formed as a result of an explosion of a launch vehicle with self-inflammable propellant components in the i...
Technique for the computational determination of the hydraulic resistance of a gas-dispersed flow
The aim of this work is to determine the hydraulic resistance of a gas-dispersed flow in a horizontal channel with a minimum of empirical data. Assuming the gas-dispersed flow energy balance as a sum of two terms: the ca...
Fire in threshing room of grain harvester: simulation of fire development and suppression with dispersed water
Methodical support for solving the practically significant problem of improvements in fire safety of grain harvesters is developed using the efficient method for the fire suppression with dispersed water when a fire emer...
Prediction of life of 12X18H10T steel in isothermal creep in uniaxial tension
The paper deals with a method of prediction of the structural material life in isothermal creep in uniaxial stationary loading, based on a strained failure criterion, which suggests that a limited state of material is me...
