Abstract
Official abstract text for this publication.
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 ) after ice has become deposited ( 31 ) on said upstream portion ( 21 ).
First claim
Opening claim text (preview).
What is claimed is: 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 (D 1 ) 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 ant…
