Abstract: A nacelle for a jet engine having a selectively operated reverse thruster which redirects air flow to a cascade during a reverse thrust operation, the nacelle including a fancowl panel configured as a stationary partial cover for a jet engine; and a translating cowl panel configured to move transversely during a reverse thrust operation so as to expose a cascade for emitting reverse thrust airflow. In exemplary embodiments, a moveable automatic translating panel, or a rotatable hinge panel, or an extension portion of the fancowl is used to preserve clearance with an aircraft wing in a nacelle clearance area.

Abstract: An aircraft panel, notably a fuselage panel of the aircraft, includes at least one opening equipped with a surround intended to accept a closing-off device that closes off the opening. The panel includes at least one exterior surface. The surround surrounding the opening is fixed to the panel, forming an interface for fitting the closing-off device, and includes at least one lip extending towards the center of the opening. The lip supports the closing-off device. The surround has an external face interposed between the exterior surface of the panel and the closing-off device. The surround includes fixing apparatus which works by gripping the edge of the opening of the panel.

Abstract: A wing box rib, joining an aircraft wing to the wing box and to the rest of the structure, extends advantageously over an adjacent part of the fuselage, having in particular an upper line situated above a junction line of the wing upper surface panel. The connection is simplified, as is the structure of the aircraft and its manufacture, a lightening is possible, and the transmission of stresses takes place in a more favorable manner.

Abstract: An aircraft structure includes a wing spar (10), with orbital frames (24, 24?, 24?) arranged in transverse planes, right and left horizontal spars (26) connected to the wing spar (10) at the upper panel (14) of the spar respectively to the right and to the left of the spar, and for each right or left horizontal spar (26), a triangular panel (50) that includes a wall (60), a first edge arranged at the horizontal spar (26), a second side arranged at the wing spar (10), and a third side at which a first rectilinear oblique reinforcement (62) connecting the horizontal spar (26) and the wing spar (10) is provided, characterized in that the triangular panel (50) includes at least one second rectilinear oblique reinforcement (64) that connects the horizontal spar (26) and the wing spar (10).

Abstract: A wing box rib (13), joining an aircraft wing (3) to the wing box and to the rest of the structure, extends advantageously over an adjacent part of the fuselage (2), having in particular an upper line (14) situated above a junction line (15) of the wing upper surface panel (3). The connection is simplified, as is the structure of the aircraft and its manufacture, a lightening is possible, and the transmission of stresses takes place in a more favourable manner.

Abstract: The subject of the invention is an aircraft panel, notably a fuselage panel of the aircraft, comprising at least one opening equipped with a surround intended to accept a closing-off device that closes off the opening, the panel comprising at least one exterior surface, the surround surrounding the opening being fixed to the panel, forming an interface for fitting the closing-off device, and comprising at least one lip extending towards the centre of the opening, the lip supporting the closing-off device, and the surround having an external face interposed between the exterior surface of the panel and the closing-off device; the panel is characterized in that the surround comprises fixing means which work by gripping the edge of the opening of the panel.

Abstract: The subject of the invention is a surround for an opening made in a panel of an aircraft, notably a fuselage panel of the aircraft. The panel comprises at least one exterior surface, the surround is fixed to the panel, forming an interface for fitting a closing-off device, and comprises at least one lip extending towards the centre of the opening. The lip supports the closing-off device and has at least one external face interposed between the external surface of the panel and the closing-off device. The surround is characterized in that it is made of at least two independent components joined together, a first component comprising the lip and a second component being fixed to the panel.

Abstract: An aerodynamic airflow deflecting device for a landing gear retracting into a housing of an aircraft, comprising at least one element for closing the housing that is, through the action of a control device, able to occupy a position for shielding at least a part of the landing gear against the aerodynamic airflow, thus constituting a noise reducing aerodynamic device. The closing element can in particular include at least one trap door element that is, through the action of the control device, movable between a first position for closing the housing, a second position allowing the landing gear to exit and a third position constituting said shielding position.

Abstract: A self-stiffened panel of preimpregnated composite. The panel is of a type including a base skin on one side of which are added and placed side-by-side U-shaped stiffeners of which the parts connecting the branches of the U are flattened against the skin, with an interfacing structure between the adjoining branches of two adjacent stiffeners The interfacing structure is a nail having a nail-head comprised of a cord of filling resin. The nail is formed from a band with a rectangular cross-section whose edge, on the skin side, is directly in contact with the adjoining surface of the skin. The nail-head is comprised of two half-nail-heads placed symmetrically in the angle formed between the skin and the nail.
