Landing Gear Fairings and Redesign

Definition

Landing gear fairings are aerodynamic structures that cover and streamline the landing gear of an aircraft, reducing drag and noise during flight. The redesign of these fairings often aims to enhance their shape and materials to further minimize airframe noise, improve fuel efficiency, and optimize the overall aerodynamic performance of the aircraft.
