Turbulence grids replicating the velocity profile (including the high-frequency part of the turbulence spectrum) of the atmospheric boundary layer (ABL) have been designed, manufactured, and tested in ONERA wind tunnels. These ABL grids are intended to improve the experimental simulation of the flow entering air inlets of aircraft engines while operating in a crosswind. It was found that the grids properly reproduced the features of the ABL flow that are relevant to this application. A test with an air inlet has confirmed that the grids can have a noticeable effect on the operating range of the air inlet and are therefore of significant interest to engine manufacturers.
