Abstract: A device for emitting digital video images may include a picture-taking unit for producing the images and a unit for forming at least one signal in the field of vision of the picture-taking unit so that the signal appears in at least some of the images produced by the picture-taking unit. The signal is formed to vary temporally, making it possible to detect any image freeze emitted by the device.

Abstract: The nose gear of an aircraft comprises a main group of at least one wheel (10) in permanent contact with the ground and a secondary group of at least one wheel (12), which is normally spaced from the ground, when the aircraft is on the ground. In the case of emergency braking due to an aborted takeoff or in the case of a blowout of a tire of a wheel (10) of the main group, the wheel or wheels (12) come into contact with the ground. This avoids an oversizing of the nose gear.

Abstract: In order to manufacture a sandwich panel using the RTM technique, a stack comprising a core (10) with open cells, a film (12) of intumescent material covering each of the faces of the core (10), a dry barrier fabric (14) covering each of the films (12) and an overlay of dry fibers (16) covering each of the barrier fabrics is placed in a mold. During polymerization of the films (12), pressurization of the mold and the presence of the barrier fabrics (14) prevent penetration of the foam into the overlays (16). The resin is then injected into the mold and then polymerized, without danger of penetration into the cells of the core (10).

Abstract: In order to avoid an operator forgetting to actuate locking mechanism interposed between two elements, such as the pod cowls (12, 14) of an aircraft engine, when said elements are in the closed position, use is made of a closure fault indicator. Said indicator comprises retractable abutment members (42, 44) automatically maintaining the two elements spaced from one another in a visible manner, when said elements are moved from their open position into their closed position.

Abstract: The present invention relates to a device for aiding the identification of subassemblies of an item of equipment (E) including a number of subassemblies and equipped with a storage unit (US) storing references. According to the invention, said device includes a memory (7) recording the references stored in the storage unit (US), an external electrical power supply means (9) for the memory (7), a means (13) of isolation both electrically and in terms of software processing, and a connection means (10) connected to the memory (7) and to which can be connected a reader (L) capable of reading and telling back the references which are recorded in the memory (7) and which relate to said subassemblies of the item of equipment (E).

Abstract: The process, in which there is carried out localized surface metallization of pieces of composite material, of the type covered on their surface with a layer (CC) of an electrically conductive material, itself coated with an electrically insulating protective layer (P) such as paint or the like, is characterized in that in line with each zone of said painted surface dedicated to a hole to be metallized, there is carried out a scraping off down to the conductive layer (CC), with the help of a metallic edge pressed resiliently and moved over the surface of the piece, stopping of the scraping off being controlled consecutively upon reaching or exceeding a predetermined threshold of electrical conduction between the conductive layer (CC) and the metallic edge and, finally, the various holes of the piece are pierced and shaped.

Abstract: A device for discharging hot air for a jet engine air inlet cowl, with a deicing circuit. The air inlet cowl for a jet engine, the leading edge of which is hollow and swept with a flow of deicing hot air, includes orifices for discharging the hot air flow to the outside of the leading edge, which form an arrangement such that at least two pressurized hot air jets passing through two adjacent orifices have, downstream of a calibration piece in which the orifices are made, different inclinations with respect to the calibration piece.

Abstract: According to the invention, the suspension pylon (3) comprises a fairing for reducing the local loss in lift and its maximum-width section (7) is located at the front of the concave and set-back rear part (4R) of the pressure face (4) of the wing structure (1). The fairing for reducing the local loss in lift (8): is housed, at least over most of its height, in the concavity of said rear part (4R) of the pressure face (4) of the wing structure (1), and comprises an underside (15) which comes close to its upper surface (13) as an aerodynamic continuation of the suction face (14) of the wing structure (1) so as to give the protruding rear part (12) of said fairing (8) the shape of a blade which tapers toward the rear and ends in an aerodynamic trailing edge (16).

Abstract: The present invention relates to a system for the yaw control of an aircraft fitted with a plurality of engines, the system (SC) comprising in particular a computation unit (16) formulating a command dr for yaw control, dr=Ka.&PHgr;c+Kb.p+Kc.&PHgr;+Kd.r+Ke.&bgr;, on the basis of the controlled roll attitude &PHgr;c, of the roll rate p, of the effective roll attitude &PHgr;, of the yaw rate r, of the sideslip &bgr; and of gains Ka, Kb, Kc, Kd and Ke which are fixed by a device (28). According to the invention, the system (SC) comprises a a device (30) for detecting any fault with an engine of the aircraft, and the device (28) is formed in such a way as to modify the values of the gains Ka, Kd and Ke relating respectively to the controlled roll attitude &PHgr;c, to the yaw rate r and to the sideslip &bgr;, upon the detection by the device (30) of a fault with an engine of the aircraft.

Abstract: A method is provided for arranging the components and power connection points within an electromechanical braking system architecture in order to better maintain isolation of the power busses, and thereby improve overall integrity of the system, while still meeting system redundancy, performance and safety requirements as in the past. In addition, a method is provided for connecting and efficiently using available power in emergency braking and parking modes.

Abstract: A process for the production of a resin piece by molding, places a self-demolding silicone membrane in a mold, and adds a catalyst to the resin to reduce the polymerization time of the resin so that the resin will not corrode the membrane.
