Abstract

A percussion fuze device, especially culotte fuze, for a rotating explosive projectile, provided with a mechanical self-destruct device comprising a first rear-facing ramp and on which the centrifugal catches of the self-destruct device are supported while the speed of rotation of the projectile remains higher than a predetermined value below which an elastic system that controls an intermediate member carrying said centrifugal fasteners begins to predominate and generates the percussion of the fuze by an axial displacement of said intermediate member forwards, characterized by the fact that said mechanical self-destruction device also includes, on the paths to the axis that the centrifugal catches must follow in their housings to escape said first ramp, a second ramp, oriented towards the front, supported by a axially mobile and free to move back mass, relative to the organ non-intermediate which is carried by the centrifugal catches, under the action of the pressure exerted on said second ramp by said centrifugal catches during its exhaust path towards the axis, a path that is thus braked in the event of an impact due to the fact that the centrifugal catches then they must overcome, in order to escape to the first ramp, the inertia force, directed forward, of said mass.
