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.

A fuse comprising a reversible airbrake intended for a projectile, wherein the airbrake comprises at least one brake disc containing at least two brake surfaces arranged on a brake ring in the form of radially protruding parts in the periphery of the brake ring which are evenly distributed around the casing surface of the fuse and arranged each behind a respective protective device arranged on the casing surface of the fuse in order to reduce the air resistance of the brake surfaces behind, wherein the brake surfaces can be extended or retracted radially sideways along the casing surface behind said respective protective device so that in the retracted position, they are concealed behind the respective protective device when viewed from the front.
