EJECTABLE AERODYNAMIC CAP FOR GUIDED MUNITION AND GUIDED MUNITION COMPRISING SUCH A CAP

摘要

The invention relates to an ejectable protective cap for a commanded munition comprising a munition body (10) of cylindrical shape with longitudinal axis ZZ', having a munition body front end (12) comprising a central part (14) intended to be steered toward a target, the cap comprising n cap portions C1, C2,...Ci,...Cn of the same shape, distributed about said longitudinal axis ZZ' and intended to cover the front end (12) of the munition body, n being an integer greater than or equal to 2, i being the rank of the cap portion, a cap portion Ci having at least one edge in contact with one edge of a cap portion contiguous with it in a respective plane of assembly (P1) of two contiguous cap portions passing through the longitudinal axis ZZ', a pyrotechnic initiator (22) per cap portion (C2), each of the pyrotechnic initiators comprising, along a longitudinal axis AA', a pyrotechnic initiator body secured to the respective cap portion Ci, a piston plunger capable of sliding in a sealed fashion via one of its ends, along said longitudinal axis AA', the free other end of the piston plunger being in contact with the contiguous cap portion in order, upon simultaneous activation of the n pyrotechnic initiators, to separate the edges of the contiguous cap portions from their respective plane of assembly and release the front end (12) of the munition body. Application: commanded or guided munitions such as those of the rocket or projectile type or missiles.
