Abstract

Abstract:

A gas dynamic model of muzzle assistant-rotating and recoil absorber for internally powered gatling gun is established based on gas dynamic equations, and the assistant-rotating force and brake force of this device are calculated. The changes of assistant-rotating and brake forces with length are analyzed by changing the lougitudinal size of this device along the axial direction of barrel. The dynamics simulations of gatling guns without and with muzzle assistant-rotating and recoil absorber are performed based on the firing dynamic model of internally powered gatling gun. The results show that the properly expanded length of center chamber and nozzle in the axial direction of barrel can effectively increase the assistant-rotating force and brake force. The brake can be used to significantly increase the firing frequency of gatling gun.

Key words: ordnance science and technology, gatling gun, muzzle assistant-rotating and recoil absorber, firing frequency, dynamic simulation
