| Abstract: | In order to realize new riot guns constant energy lethality,this paper puts forward the addition to rigid outthrust in the tube to increase the engraving resistance for projectile,establishes variable muzzle velocity model for the rigid outthrust and uses simulation software LS-DYNA to explore the relationship between the bugle volume and the muzzle velocity.At the same time,through adjusting the bugle volume of outthrust protocol underl2J/cm2,16J/cm2,22J/cm2three energy lethalities,it works out the variable muzzle velocity shoot design scheme. |
