Bullets Flying Stability Study

Research the stability of bullets ballistic is less at home.The stability of bullets on fuse arming and the end of damage is of great significance, it needs to further explore.The purpose of the paper is to build mathematical model of bullet movement, analyse the bullet motion, in theory to explain the phenomenon of failure and technical problems, find out the impact on the stability, improve the technical measures and the reliability of the bullets fuse, duide the design of the new bullet.In addition, the research can offer the reference of the design of body opening and assess the ammunition operational effectiveness.The paper first analysis the force and torque on the bullets, then establish the movement mathematical model, solution of the above model, finally development the design theory of the bullets stability.
