摘要:
A device for protecting a front spar structure (12) of a central casing (13) of an aircraft wing and equipment (14) located in said wing. The device comprises a shielding surface (222) extending along the front of a front spar of a central casing (13), from the intersection surface (3) between the wing and the fuselage delimited by the wing root, transversally to this intersection surface (3), up to a first rib of the central casing (13) partially surrounding the equipment (14). The device thus protects the equipment (14) located in the zone between the wing root and the first rib of the central casing (13) of the wing.
摘要:
The invention refers to an aircraft aerodynamic surface (10) comprising a torsion box having an upper skin (11), a lower skin (12), and a front spar (9), and a leading edge (1) having an external shell (7) and an impact resisting structure (8). The external shell (7) may be shaped with an aerodynamic leading edge profile, being configured to provide Laminar Flow Control (LFC) to the leading edge. The impact resisting structure (8) is spanwise arranged between the external shell (7) and the front spar (9), and is configured for absorbing a bird strike to prevent damage in the front spar (9). Also, at least one of the external shell (7) and the impact resisting structure (8) is fitted with the upper and lower skins (11, 12) of the torsion box to thereby facilitate leading edge exchange.

The presently disclosed subject matter includes, inter alia, a method and system for reducing damage to an airplane by birds. A high pressure jet is selectively triggered on to birds by a jetting system that is mounted on the airplane. Information indicative of motion of a bird in a vicinity of the airplane is received and analyzed and the high pressure jet is selectively triggered onto the bird in response to a result of the analysis of the information.
摘要:
The present invention relates to a method for inspecting impacts (Ii) present on an internal face (104) of a fan casing (100), said method being characterized in that it comprises the following steps consisting in: - spotting (201) a first impact (I1) present on the internal face (104) of the fan casing (100); - delimiting (202) an inspection area (106) containing said first impact (I1); - spotting (203) the various impacts (Ii) present in the delimited inspection area (106), said various spotted impacts forming a set of impacts to be considered; - measuring (204), for each impact (Ii) that is to be considered, the depth of length of said impact (Ii); - for each impact (Ii) to be considered, determining (205) a harmfulness value, using at least one chart (300; 400) relating the depth and length of each impact to be considered to a level of harmfulness; - determining (206), for the inspection area (106) containing the first impact (I1), a total harmfulness value by adding together the harmfulness level determined for each impact (Ii) to be considered.
