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).

Abstract: A blanking-off element, intended to be mounted on one end of a tube for storing and launching a munition to protect its interior from external attacks, embodies a cap intended to extend over the entire section of the tube end and to be fixed in a tight manner right along the edge of the tube end and to become detached at least partially with respect to the end at the moment of launching, characterized in that the cap is fixed to the interior of a protective cover made from pliable material which has a retaining lug fixed to the outside of the tube close to the end, whereby the cap is recovered by the protective cover at the moment of launching.
