Abstract: A nacelle for a ducted fan turbojet engine comprising an engine. The nacelle comprises a fixed cowl, an upstream wall bounding off, with the engine, a working section for a secondary flow, a movable cowl with an interior wall and an exterior wall, and movable in translation between a closing position where the exterior wall adjoins the fixed cowl and the interior wall prolongs the upstream wall, and an opening position where the exterior wall is distant from the fixed cowl so as to open a window and the interior wall is distant from the upstream wall, an inverter flap between the interior wall and the exterior wall mounted to be free in rotation about an axis of rotation situated on the interior wall and a drive mechanism for moving the movable cowl.

Abstract: A cellular sound insulation structure and associated aircraft, a cell of which is provided with a diaphragm which includes a membrane having at least one orifice passing through a thickness of the membrane, and at least one tube surmounting the orifice and extending from a face of the membrane into one compartment of the cell, the tube comprising a free end, forming an acoustic outlet, which is positioned at a distance (p) from the base cross section of the cell. Also, a method for manufacturing such a cellular sound insulation structure, as well as to a tool for inserting a diaphragm into a cell. Such a cellular structure makes it possible to treat a wider acoustic frequency spectrum, and its acoustic dimensioning as well as its manufacture are simplified.

Abstract: An acoustic panel for an aircraft nacelle air intake comprising a resistive skin perforated by noise absorption holes and a core against which the resistive skin extends, wherein the resistive skin has a smooth visible face and a castellated rear face with alternating ribs and grooves. The noise absorption holes are formed exclusively in the grooves, i.e., in a zone where the skin is less thick, which enables the holes to have a diameter that is both greater than the thickness of the skin and small enough not to have any impact on drag. The mechanical strength of the resistive skin provided by the ribs ensures that the lesser thickness of the resistive skin in the grooves does not render the resistive skin overly flexible.

Abstract: An aircraft engine nacelle comprising an icing protection system and an icing protection method for such an aircraft engine nacelle. The aircraft engine nacelle comprises an air inlet comprising a lip, a tubular air inlet piece and an icing protection system. The icing protection system comprises an icing prevention means powered continuously by a first electrical energy source and wholly or partly covering the lip, a de-icing means powered by a second electrical energy source covering the tubular air inlet piece and a controller configured to acquire a current total air temperature value, and control the second electrical energy source as a function of the current total air temperature value.

Abstract: An air intake structure for an aircraft nacelle including an air intake lip with a U-shaped cross section which is open towards the rear, with a rear end, an acoustic panel including an inner wall, wherein the air intake lip has at a rear end a contact surface oriented towards the inside of the air intake lip, in that the contact surface takes the shape of a bevel which points towards the rear and against which the inner wall is placed, in that at the point of the bevel, the inner wall runs on from the air intake lip and in that level with the contact surface, the air intake lip is fixed to the inner wall by first fasteners. The bevelled shape restricts the possibility of dust and water being halted in their progress and blocking up the air intake structure as a result.

Abstract: A nacelle including a fixed structure, a central cover mounted on the fixed structure, a fan cover mounted on and articulated to the central cover between an open position and a closed position, and locking means that are distributed between each fan cover and the fixed structure and that are designed to assume a locked position in which they lock the fan cover to the fixed structure and an unlocked position in which they do not lock the fan cover to the fixed structure, in which the locked position can be adopted only when the fan cover is in the closed position, and in which the unlocked position can be adopted whether the fan cover is in the open or closed position and wherein the locking means are locked and unlocked by a rotation around a longitudinal axis of the nacelle.

Abstract: A production method for an acoustic panel comprising a step of producing a composite structure, a step of providing inserts, wherein each insert comprises a nozzle formed as a hollow cylinder with a through-bore and a cap comprising a base formed as a cylinder and a cover formed as a cone, and wherein the base is accommodated in the bore, a step of positioning the inserts in the composite structure by penetration of the cover into the composite structure so that the bore opens at one side and the other of the composite structure, a step of polymerizing during which the composite structure with the inserts is polymerized, a step of removing the caps, a first step of fixing a honeycomb structure to the polymerized composite structure, and a second step of fixing a rear skin to the honeycomb structure.

Abstract: A structure establishing a sound insulator and including a first plate, a second plate having holes therethrough, and a web stuck between the plates. The web includes a plurality of intermediate strips perpendicular at least to one of the plates, a plurality of folded strips which are folded in a zig-zag formation, each folded strip being arranged between two successive intermediate strips, and establishes, with the intermediate strips, triangular prisms, where, for two folded strips on either side of a same intermediate strip, the generator of the triangular prism of one of the folded strips forms an acute angle with respect to the first plate, and the generator of the triangular prism of the other folded strip forms an obtuse angle with respect to the first plate.
