Abstract
Guided artillery projectiles will offer substantial improvement in the accurate delivery of effects on target. A number of projects are under way in several countries with the objective to develop and field precision guided artillery munitions. A study of the aerodynamic characteristics as well as a Monte Carlo parametric analysis were carried out on a 155 mm shell concept equipped with a four-canard roll-decoupled course correction fuze. The course correction fuze concept studied is shown to efficiently counteract the gun azimuth and elevation perturbations. It can also correct the muzzle velocity perturbations when particular launch conditions are met, but it has a minimal effect on correcting the wind perturbations. The best accuracy results are obtained at low gun elevation, high muzzle velocity and short guidance lock delay.
