  • Application of leading edge serration and trailing edge foam for undercarriage wheel cavity noise reduction
    Patent number: 11485471
    Abstract: A system for use in an aircraft or other system in an ambient airflow includes a body defining a cavity having an opening exposed to ambient airflow, with a cavity interface defined by body structure surrounding the opening. The cavity interface includes a cavity floor opposite the cavity opening, a leading edge facing away from the ambient airflow, a trailing edge facing the airflow, and a rear wall extending between the trailing edge and the cavity floor. A panel of sound-absorbing material is attached to and covers substantially all of the surface area of the rear wall of the cavity, and minimizes emanation of a predetermined range of audible sound frequencies from the cavity. The system may include an elongated serrated element connected to body and extending along the leading edge and arranged flush with the leading edge.
