Abstract
The invention relates to so-called fuze damping in projectiles, in particular, those provided with a built-in firing delay. Thus, a projectile (1) is provided having a rear part (1a) and a fuze (2), wherein at least one damping element (7) is inserted between a fuze base (5) and the projectile (1) and/or between a fuze shoulder (6) and a possible threaded ring (4), or similar attachment element. The damping element (7) is in the form of a disc, ring or pot, and is composed of a material with a lower acoustic impedance than the material of the projectile (1).
Claims17
A projectile comprising:
- (a) a rear part;
- (b) a fuze;
- and
- (c) at least one damping element inserted between a fuze base and the rear part of the projectile, or between a fuze shoulder and an attachment element, or between the fuze base and the rear part of the projectile and between the fuze shoulder and the attachment element, wherein the fuze is a delayed fuze that is initiated by residual forces when the projectile penetrates a target, and the at least one damping element comprises a material matched to a load spectra of the projectile so that damping by the material is sufficient to absorb axial oscillations resulting from when the projectile strikes the target so that operation of the delayed fuze by residual force initiation is ensured.
