Abstract
The base fuze of a spinning projectile possesses a detonator capsule which is pierced by a firing pin. The firing pin is connected to a hammer sleeve. An inertia body is arranged behind the hammer sleeve in order to improve the response sensitivity of the base fuze. Upon impact of the projectile at the target, the inertia body, due to the inertia thereof, drives the firing pin conjointly with the hammer sleeve against the detonator capsule. This inertia body is subdivided into a number of sector-shaped portions which contain substantially cylindrical sections and truncated conical sections. A bore of a fuze housing within which the inertia body is arranged possesses a shoulder. This shoulder serves to support the truncated conical sections of the inertia body such that due to the spin of the projectile an axial force is produced which acts upon the inertia body causing it to impact against the hammer sleeve.
