Can't grilles be placed in front of jet air intakes to stop seagulls
killing engines?


Yes and No

If the grill is heavy enough you can stop a bird it will get shredded
and the bits will go through the engine However that heavy of a grill
and you wont get enough air flow as for a light grill Imagine a bird at
500mph hitting it The bird would go right through the grill so no benifit.
