Abstract: A fuse is provided with a reversible airbrake intended for a projectile, wherein the airbrake is arranged such that errors which occur in the flight path of the projectile can be corrected by performing one or more extensions and retractions of the airbrake. The airbrake includes at least two braking surfaces symmetrically arranged each behind a respective protective device arranged on the casing surface of the fuse, wherein the brake surfaces can be extended and retracted in a rotational direction behind the at least two protective devices via a twist shaft arranged centrally in the fuse.

Abstract: In a brake for detachable arrangement on projectiles, the brake is configured with a surface which is situated in the direction of travel of the projectile, where the surface is larger than a surface given by πR2-πr2, where R is the outer radius of the brake and r is the inner radius of the brake. A method for braking projectiles is also provided.

Abstract: A method is provided to improve the impact point for at least one subsequent projectile fired towards a target, launched after an initial projectile, where the subsequent projectiles can alter their course, based on information on the previous projectiles' time of automatic detonation, to improve the ability to detect a target. A projectile and a fuse are also provided.
