Steering Troncon for guided munition

The invention relates to a steering section for guided munition comprising a driving body (50) having n control surfaces may be either in a folded position in the pilot member (50) or in an extended position protruding from the outer surface (52) of the control body to achieve guidance of the munition, the control section includes a locking mechanism (60) of the n control surfaces in a folded position in the pilot member (50 having a latch support (62) integral steering body, a fixed sleeve (64) integral with the lock carrier (62) having a locking barrel (110), a movable sleeve (66) surrounding the fixed sleeve (64) and which can slide longitudinally along an axis AA ' the lock barrel (110), the mobile sleeve (66) having, outside the fixed sleeve (64), a free end (130) collaborating with the n control surfaces (G1, G2, G3, G4) for maintain in their folded position in the body of steering (50), a locking device (174, 176, 194, 200) in translation along the axis AA 'of the movable sleeve (66) on the lock barrel (110) which can be deactivated by an unlocking force F to trigger a translation by sliding of the movable sleeve (66) on the lock barrel (110) and the release of the n control surfaces may move from their collapsed position to their deployed position.
