The tilting rotor, including the pyrotechnic charge that it carries, is arranged so as to have no imbalance. The pyrotechnic charge is entirely symmetrical with respect to the middle transverse plane of the housing. The rotor is arranged so as to have a principal axis of inertia, and the resting position of the rotor is such that its principal axis of inertia forms in resting position an angle of 90 DEG with the axis of the fuse, said resting position being then a position of unstable equilibrium from which, on gyration of the fuse, the rotor seeks to reach its active position through an angular travel of 90 DEG , in one direction or the other, by reason of the appearance of a restoring torque tending, in the field of centrifugal forces and as soon as the rotor is separated however little it may be from its resting position in unstable equilibrium, to merge, that is to say to align, the principal axis of inertia (XX) of the rotor and the axis of gyration (YY) of the fuse, the pyrotechnic charge housed in said rotor then being aligned with the upstream percussion element and the downstream element of the pyrotechnic chain of the fuse.
