Abstract
A stretchable mesh material extends across the opening of a cavity of the landing gear of an aircraft when the landing gear is in the deployed position. The mesh material alters the flow of air across the opening of the landing gear cavity and significantly reduces the amount of noise produced by the wheel well at low-to-mid frequencies.
Claims18
A method of reducing noise generated in connection with a landing gear cavity of an aircraft having a deployable landing gear, the method comprising:
- providing an elastic membrane;
- securing the elastic membrane to the aircraft;
- positioning the elastic membrane so it extends across at least a substantial portion of an opening to the cavity when the landing gear is in a deployed configuration and alters air flow across the opening to reduce noise from the opening while the landing gear is in the deployed configuration.
