Recent studies of engine bird strikes reveal that approximately 50% of engine bird strikes damage the engine(s). The risk of engine damage increases proportionally with the size of the bird and with increased engine thrust settings.
I wonder where they got the data from to deduce the effect of thrust vs damage. Seem like thrust goes with AC speed which goes with startle affect at altitudes where birds are commonly ingested.
In my view thrust is not a significant parameter in ingestion damage Kinematics is i.e. vectors
