The present invention relates to an air intake grid (11) having a mesh (12) provided with elongate elements (16), two adjacent elongate elements (16) crossing at a node (14, 15). At least one elongate element (16) is surrounded by at least one anti-icing member (20), said anti-icing member (20) having a downstream portion (22) matching the shape of said corresponding elongate element (16) and an elongate upstream portion (21) that is resilient and that vibrates under the effect of vortices generated by a flow of air (30) passing through said grid (11) af...


1. A method of avoiding clogging of a stationary grid of an air intake in icing conditions, the method comprising: providing a grid having a mesh with a plurality of elongate elements, including two adjacent elongate elements crossing at a node, each elongate element extending in a long direction (D1) between a first node and a second node;mounting an anti-icing member around at least one elongate element between the first node and the second node, the anti-icing member having a hollow core with a cross-section corresponding to a cross-section of the at ...
