Uncle Samuel is trying to "legislate" common sense on the drone issue. My CFM engines could suck up a drone with zero -or slight damage if any at all. A motor or two or camera gimbal that made it into the core section would do some damage but that is a pretty unlikely scenario.
Dumb a$$es doing dumb stuff are flying into buildings in Manhattan and near planes on final or departure. The whole FAA involvement with drones defies their years of refusal to get involved with RC planes.
We have a bunch of morons nowadays who don't exercise any common sense at all. And because a few crap their pants, we all have to wear diapers. It will be that way until we stand up and tell them, 'NO MORE!"
I plan on building my drone next year. I plan to do reasonable things with it and not to spy on people. Uncle Samuel can kiss my big white behind.
The core inlet is the thin strip around the spinner. That's where the air going into the engine for combustion goes. The parts on the "innards" are smaller and more fragile but, the engine is designed so getting crap into the core is very difficult.
Everything else is fan and those fans can gobble up all manner of things without suffering much damage. We used to regularly fly with blades that had a corner missing or a bent edge. At $10,000 apiece, they are pretty awesome pieces of technology. A drone could go right through one of these fans and never leave a mark -on the engine that is.

This engine is brand new, hanging on a 737-800 and it runs about $15 mil apiece. If you look at the blade at about 2:30, there is a slight mark on it. That may have been made by a small bird.
