I wonder how the PW1100G will handle the shock of a fan blade out or bird ingestion, especially the gear system?
Likely about as well as a turboprop tossing a fan blade.
However, with the slower-turning fan, the fan blades see lower centripetal forces and can thus be lighter. So, imbalance load will be less than with a traditional direct-drive fan.
But as with all things mechanical, your mileage may vary.
