20090320709 | SAFETY LIGHTER FOR PYROTECHNIC DEVICE - Embodiments of the invention relate to a safety lighter intended to initiate the combustion of a pyrotechnic device, the lighter including a lighter body ( | 12-31-2009 |
20100308153 | Device for Opening and Locking a Tail Unit for Ammunition - A device for opening and locking a tail unit is provided. The tail unit includes a body and at least one fin, pivotable relative to the body along a first axis, that has a projection that forms an element. The device comprises a control ring, slidable relative to the body along a second axis, that includes a component, forming an element, that bears against the projection to deploy the fin, the second axis being non-parallel and non-secant to the first axis. A means for shaping one of the elements during translation along the second axis of the control ring towards the projection of the fin is provided on the other element. The body includes a bearing surface to support the fin during shaping, in which the support of the fin on the bearing surface corresponds to the deployed position of the fin. | 12-09-2010 |
20120137916 | Device for Hardening a Mechanical Propulsion System Connection for a Mortar Round and Round Comprising Such a Connection - A self-propelled munition having a munition rear body of circular cylindrical shape of diameter D | 06-07-2012 |
20130145952 | Ammunition with Device for Holding the Pyrotechnic Charge of the Ammunition - Ammunition comprises, along a longitudinal axis, a fuse in the form of a tip, an ammunition body and a skirt, the ammunition body of cylindrical form with axis of revolution merged with the longitudinal axis, having, between a front end and a rear end, a circular cylindrical wall delimiting a loading compartment containing a pyrotechnic charge, the ammunition body being sealed at its front end by the fuse and at its rear end by the skirt attached to the ammunition body. The ammunition body includes, in the loading compartment, between its two ends, a central core having n fins each comprising at least one edge, in the axis of revolution, attached to the skirt, n being greater than or equal to 1, to separate the pyrotechnic charge into at least two portions on either side of a given fin Ei. Applications are to cannon or mortar type ammunition. | 06-13-2013 |
20130193264 | Guided Munitions Protected by an Aerodynamic Cap - In the field of steered munitions intended to destroy a target after at least one flight phase followed by a target approach phase, a munition comprises a munition body of cylindrical shape of longitudinal axis having, on the same side as a front end of the munition which is the end intended to be directed toward the target, a front body comprising an optic of a guidance device that guides said munition toward the target, a cap for protecting the optic, secured to the munition body, characterized in that the protective cap comprises at least one recess having a pyrotechnic device intended to destroy said protective cap so as to free the optic and make the munition guidance device operational during the target approach phase. Application: steered or guided munitions such as those of the rocket or projectile type, or missiles. | 08-01-2013 |
20130193265 | Steering Section for Guided Munition - A steering section for guided munition comprises a steering body having n control surfaces folded inside or deployed protruding from the external surface. The steering section comprises a locking mechanism for the n control surfaces folded inside the steering body having a lock support secured thereto, a fixed sleeve secured to the lock support comprising a locking barrel, a mobile sleeve surrounding the fixed sleeve and slideable longitudinally along the locking barrel, the mobile sleeve comprising, on the outside of the fixed sleeve, a free end collaborating with the n control surfaces to keep them folded inside the steering body, a translational-locking device locking the translational movement along the mobile sleeve along the locking barrel deactivatable by unlocking force to trigger translational sliding movement of the mobile sleeve along the locking barrel and release the n control surfaces which can then move from their folded position into their deployed position. | 08-01-2013 |
20130264425 | SEPARABLE STREAMLINED NOSE CONE FOR A GUIDED MUNITION, AND GUIDED MUNITION INCLUDING SUCH A NOSE CONE - A separable ejectable protective nosecone for a guided munition comprises a munition body of cylindrical shape of longitudinal axis ZZ′ having a munition body front end comprising a central part intended to be directed toward a target of the munition. The nosecone comprises, at the munition body front end and covering said front end, n contiguous nosecone portions of the same shape distributed about said longitudinal axis ZZ′, one respective pyrotechnic device per nosecone portion. Each of the pyrotechnic devices comprises a pyrotechnic device body secured to the munition body, a pusher piston in contact with the respective nosecone portion. Simultaneous activation of the n pyrotechnic devices separates the edges of the nosecone portions from their respective plane of assembly in order to free the front end of the munition body. Application: Steered or guided munitions such as those of the rocket or projectile type or missiles. | 10-10-2013 |
