Predicting the Flight Behaviour of a Guided Projectile Through a Six Degrees of Freedom Trajectory Model

We develop a comprehensive six degrees of freedom (6-DOF) model to examine the flight behaviour of a guided projectile. A 120-mm mortar is used as a representative projectile system in the work. The analysis is carried out using the developed code for varying muzzle velocities and launch angles in order to predict the path behaviour such as maximum range and altitude. In the 6-DOF model, the projectile is assumed as a rigid body of finite length with distributed mass. In order to estimate the precise location of the projectile, every DOF is tied to a coordinate which defines its position at every instance.
