I did a research paper years ago looking at 280+ propeller injuries at the NTSB. The mechanism of injury, however is really different, as there is a lot of mass and a lot of momentum involved in aircraft propeller movement, and even at idle there is combustion force at play. In addition, aircraft propeller injuries often involve multiple blade impacts in a very short period of time.

This question may be better answered by a physicist, calculating mass, speed and force compared to compression strength of bone.
