Abstract: An aircraft landing gear (10) comprising a noise-inducing component region (12) and an airflow disruption element (16) having a first configuration in which it is spaced from, and arranged in an upstream relationship with respect to, the noise-inducing component region such that, in use with the landing gear deployed, the airflow disruption element faces, and at least partially disrupts, an airflow(A) moving towards the noise-inducing component region, wherein the cross-sectional area of the airflow disruption element is less than the cross-sectional area of the noise-inducing component region.
