Abstract
In the paper the simulation research of target-homing accuracy of a spinning object in flight is presented. Numerical calculation was based on the mathematical model of three-dimension flight of jets control projectile according to the proportional navigation method. Control jets are small orifices in center of gravity and sides of the object to be controlled, through which gas can be ejected. This gas may be generated from compressed gas in bottles or by burning fuel. The influence of the guidance method on the mortar missile flight trajectory, and thus affects such guidance criteria as duration of flight to target, normal accelerations of the missile, guidance error and the possibility of attacks zone was analysed. Achievements of example calculations were presented in the tables and on the graphs.
