Title    The 6-DOF System Simulation of exterior ballistics of Spin-stabilized Projectile Based on MATLAB
Abstract
With the development of the science and technology in computer simulation, system simulation is an advanced technology of computer application. The technology is used so widely in fields of national economy and national defense build. At the same time in order to adapt for the request of modern war and the progress of the science and technology, the exterior ballistics has rapidly developed in the decades. Because the simulation technology is an economical and effective means in developing and making modern weaponry, it has been a sticking point impetus in the science and technology stratagem of national defense. Based on the MATLAB and system simulation’s workflow, this text was carried on the system simulation of exterior trajectory; the main contribution of the text has followed:

At first of all,we try to learn and be familiar with the development environment of MATLAB/SIMULINK.Second,in combination with ballistics system at home and abroad,to master the basic theories of the exterior ballistics system.
Thirdly,write SIMULINK program to realize the 6-DOF simulation of the projectile in free flight.At last,write MATLAB program and plot the ballistic data images.
