ARMS BARREL

摘要

A barrel of arm is arranged as two cylindrical tubes connected to each other with axial symmetry at long axles of those, with collar for fixation of barrel to the stand of arm frame fixed on one of the pipes. To make impossible use of shells with fatal effect outer diameter of the barrel with respect to the outer diameter of the shell is taken at ratio 1.1178-K-dz.g.v..<de.st.vos.<1.369-K-dzgv . Difference of the outer diameter of working section of the barrel and the diameter of the cartridge chamber are taken at ratio 0 mm<dz.st.rob-dpat..<1.1-K mm with account of coefficient K characterizing material of which the barrel is made where 0<K<10. .
