Abstract

Disclosed is an impact fuse in which an operation time of a firing pin is changed according to penetration or recoiling. The present invention relates to a mechanical impact fuse capable of intelligently changing an operation time of a firing pin by determining a penetration or recoiling situation according to the size of a speed change amount generated in a bullet when a target of a projectile is hit, wherein the mechanical impact fuse comprises: an outer sensitive ring (20) which is moved forward by a hitting impact from a front side; an inner sensitive ring (22) which is restrained thereby and is released from the restraining by the forward movement to be relatively moved forward or backward; and an inner sensitive spring (23) which is arranged in a compression state between the outer sensitive ring (20) and the inner sensitive ring (22) to push the same with respect to each other. When the outer sensitive spring is in the compression state and the inner sensitive spring is in an unrelaxed state, the forward movement distance of the inner sensitive ring (22) for fixing and releasing a firing pin (24) is set to be shorter than the total forward movable distance of the outer sensitive ring (20). When strong impact force, which is failure of penetration of a target is applied, the outer and inner sensitive rings move as if the rings are integrated, so that the firing pin is immediately fired. When low impact force, which is success of penetration of a target is applied, the inner sensitive ring moves to be closer to and farther away from the outer sensitive ring so as to delay firing of a firing pin. Accordingly, it is possible to implement an intelligent warhead capable of exhibiting efficiency by being projected to various targets even without relying on an electronic timer.
