Abstract: A novel electric firing mechanism which is imbedded in the rifle grip is proposed for the disturbance to line-of-sight (LOS) and low action speed caused by manual firing. The structure and operating principle of the electric firing mechanism are illustrated. A parametric model is established. The electromagnet force of the electric firing mechanism is simulated in COMSOL, and the disturbance to LOS and response time of the electric firing mechanism is tested. The result shows that the mechanism is capable of electrically firing, the azimuthal disturbance of electric firing to LOS is reduced to 1/5 of manual firing, and the response time is 35 ms, which is much faster than manual firing speed. The electric firing mechanism will be helpful to catch the firing time precisely.
