Abstract
The invention relates to a mechanical self-percussion fuze (1) for a non-spinning round, having a firing pin (14) disposed along a central axis (A), a primer (17′) provided in a primer holder (17) that is movable about an axis of rotation (B) that is parallel and off-centre with respect to the central axis (A) between a storage position in which the primer (17′) is off-centre with respect to the firing pin (14) and an armed position in which the primer (17′) is aligned with the firing pin (14), and safety devices coupled to the primer holder (17) in order to keep the fuze (1) in a safe state until at least two mutually independent physical phenomena linked to the firing of the round occur. The fuze (1) has a wind turbine (11) designed to be driven in rotation by the relative movement of the air during the flight of the round and to transmit this rotational movement to the primer holder (17) only after the safety devices have been removed.
