Abstract

The invention relates to a landing gear including a noise reducing means (2) comprising at least one individual net (5) which is disposed close to a component (4) of the landing gear.

Description

technical field [0001] The invention relates to an aircraft landing gear equipped with at least one noise reduction device. [0002] More specifically, said undercarriage is of the type comprising at least one noise-reducing device, which can be placed in one of two positions, namely a retracted position and an extended position, in the usual manner, the noise-reducing device Associated with at least one constituent element of said undercarriage (pipes, struts, fastening means, ducts, etc.). [0003] The invention applies to all types of undercarriage, and in particular applies equally to the nose and main undercarriage, whether the undercarriage is under the wing or under the fuselage. Background technique [0004] It is already known that aerodynamic noise is a key parameter in aeronautics, and that various new aircraft, especially for certification, must comply with international regulations imposed by ICAO (the English acronym for "International Civil Aviation Organizat...
