The goal of the work: development and creation of the most effective samples of shot devices sound level reduction (SDSLR) of hand fire-arms meeting to modern requirements. Research methods: generalization of previous theoretical and experimental researches and tests on the most modern (SDSLR) hand fire-arms development. Theoretical bases of (SDSLR) creation with helical internal elements, and the central perforated tube are developed. The program of (SDSLR) efficiency calculation taking into account means of helical internal elements application is developed. The design and technological documentation by which 39 new types of (SDSLR) are made is issued. The comparative analysis has shown that the produced samples do not concede foreign samples. The most effective (SDSLR) samples are implemented. Product Description popup.authors popup.nrat_date 2020-04-02 Close
