The present paper summarises the main findings of both experimental and numerical acoustic applied research on landing gears carried out by Messier-Bugatti-Dowty and partners since the first collaborative project initiated fifteen years ago. Experimental tests performed in wind-tunnel have highlighted many conclusions about landing gear noise sources and associated low noise solutions. Recent CFD studies on detailed landing gear geometries extend the experimental results and even more; allow optimization of low noise solutions identified during experimental campaigns and confirmed by simulations.
