Experimental investigations for the guidance of a medium-caliber projectile by using a single impulse thruster located at the center of gravity are presented. Free-flight tests were performed on a proving ground for modified 40 mm Bofors projectiles equipped with a complete pyrotechnic impulse-thruster chain, including a impulse thruster, a high safety electropyrotechnic detonator, and a safety and arming device that was designed especially to reach the required specifications in terms of response time and safety. Modified projectiles were launched with a 40 mm rifled gun. The functioning of the impulse thrusters during the flight and the projectile behavior were observed by means of radar and a high-speed video tracking system. Dispersion of the shells was precisely observed on a target located at the end of the trajectory. The results have shown that projectiles are clearly diverted from their normal ballistic trajectory with a reproducible deflection angle.
