Airframe noise, produced by unsteady flow around aircraft structures, is an important source of aircraft noise during approach and landing. Sound radiating from the undercarriage is a major contributor to airframe noise. This type of noise is broadband in nature, caused by the complex unsteady flow field associated with the multitude of bluff bodies of various sizes and shapes that collectively make up a landing gear. Previous noise reduction concepts rely on flow alteration and shielding of the more critical gear subcomponents such as the main post, torque links, etc. Such concepts include fairings made of flexible and rigid materials, porous fairings, and wire mesh screens.
