Abstract

This paper describes the landing gears airframe noise study research work in the EC co-financed "Significantly Lower Community Exposure to Aircraft Noise" (SILENCER) project. The landing gears airframe noise research include the study of gear-wake/gear interaction effects; the low noise landing gear design with add-on treatments and the advanced low noise landing gear design. Full scale optimized add-on treatments will be manufactured and flight tested on an Airbus A340 aircraft. Advanced low noise main and nose landing gear design of A340 size will be manufactured and wind tunnel tested in the German-Dutch Wind Tunnel (DNW-LLF). Together with other noise reduction treatment designs relating to engines and airframes conducted in the same project, it is expected that a total reduction margin of several EPNdB can be demonstrated through these large scale tests.
