Abstract: A deflecting device for protecting a jet engine of an aircraft from damage caused by a bird strike. The bird strike deflection device attaches to an opening in the front of a cowling of the jet engine to shield an engine air intake from ingesting a bird that would otherwise damage the engine. A conically shaped screening portion having an open mesh pattern is attached to the cowling in a convex orientation. A perimeter of the screening portion terminates in a rim sized to fit the engine intake opening in the cowling. The rim may be directly attached to the cowling or an attachment flange may connect the rim to the cowling. The deflecting device may be completely removable from, hingedly attached to, or integrated directly into the cowling.
