Abstract (en)
[origin: EP0884554A1] The lateral divergence control procedure involves modulating the acceleration of the horizontal divergence of a projectile due to the gyroscopic effect by varying the centre of its aerodynamic thrust. This is achieved by equipping the rear section (3) of the projectile with retractable fins (4) to modify the pressure distribution on the projectile at any given instant during its trajectory. The centre of thrust is moved towards the rear of the projectile to apply the required divergence projection. The fins are deployed radially at a predetermined angle in relation to the projectile's lengthwise axis so as not to counteract its roll speed. In certain cases the fins can be deployed by the effect of centrifugal forces.
