Abstract: According to the invention, the balance weights of the missile are made from pellets whereof the particle size is at most equal to 1 mm which is enclosed in a closed package.

Abstract: The invention relates to a safety arming system for an explosive charge. According to the invention, the system comprises: an arming actuator (4) for moving a sleeve (19), supporting a detonator (20), from a fixed safety position to a fixed armed position; and a disarming actuator (5) arranged opposite the arming actuator (4) and capable of returning the sleeve (19) from the fixed arming position to the fixed safety position.

Abstract: The system of the present disclosure includes at least one flow deflector located outside the nozzle of the mobile and hinged on the rear bottom of the latter, and angular orientation means for the deflector by rotation about the longitudinal axis of the nozzle.

Abstract: According to the invention, in order to lift said safety detent, use is made of a multi-vane fan (5), which is arranged inside the fuselage (2) of the projectile, but the vanes (4) of which pass through said fuselage (2) via a lateral opening (3).

Abstract: According to the invention, the marking device has a shape of revolution and comprises a casing (1) with a conical bottom (8) closed off by an obturator (2), fixed in a sealed manner to said casing (1). Inside said marking device there is a block (15) of compacted marking product.

Abstract: A blanking-plug system for blanking off an orifice of a pipe, particularly for blanking off an orifice of a duct for introducing air into the combustion chamber of a ramjet. The blanking-plug system (16) comprises at least one blanking plug (15) comprising a glass plate (18) which is able to completely blank off said orifice (8) of the pipe (7); and at least one device (17) for destroying said glass plate (18) of said blanking plug (15). Said blanking plug (15) additionally comprises a plurality of elastomer protective elements (21) which are fixed on at least one first face (22) of said glass plate (18) which is likely to be subject to attack, these elements being separated from one another by a predetermined maximum distance at most, and completely covering said first face (22).

Abstract: A shut-off system for an orifice of a duct, particularly for an orifice of an air inlet passage that allows air into the combustion chamber of a ramjet, includes a shutter for shutting off the orifice of the duct, and a controllable actuating device capable of acting on the shutter to uncover the orifice. The shutter includes a removable cap which is held on the duct and a locking device which keeps the cap on the duct by at least one locked jaw, which is unlockable. The actuating device includes at least one controllable striker which is capable of unlocking the jaw in such a way as to cause the cap to be ejected from the duct and to uncover the orifice.

Abstract: Air intake and flying device, particularly a missile, equipped with such an air intake. The air intake (1) consisting an elongate duct (4) equipped with at least one roughly planar face (7A), and a moving ramp (8) which is arranged on the outside on the planar face (7A) of the duct (4) and which can be moved in translation over said planar face (7A) along the duct (4) and brought into one of two stable positions, namely a retracted position in which it is set back from the air inlet end (5) of the duct (4) on the planar face (7A) of the duct (4), and a deployed position in which, while being partially arranged on said planar face (7A), it protrudes beyond the duct (4) at its air inlet end (5).

Abstract: A device supports a motorized flying instrument in a wind tunnel. To carry out tests in a wind tunnel on a motorized flying instrument (10), with the motor on, under different attitudes hands off, the instrument is connected to the fixed structure (15) of the wind tunnel (11) by a mounting device (12) at least one of the supports (14, 16) of which is fitted with a length adjustment system, such as a hydraulic jack (28). This jack (28) is remote controlled, in real time, by a control system (42).

Abstract: Blanking-cap system for an orifice of a duct, in particular for an orifice of an air-intake duct into the combustion chamber of a ramjet. The blanking-cap system (16) includes a glass blanking cap (15) and a destruction device (17) which comprises a projectile (18) capable of destroying the blanking cap (15), and a controllable projection means (19), which is capable of projecting the said projectile (18) and which is arranged outside the conduit (7) while being oriented in such a way as to be able to project the said projectile (18) onto the said blanking cap (15).
