There is a ton of data on bird collisions which are a decent analog to drones.  I worked on a Twin Otter that hit a seagull at ~ 120 knots.  The hit was on the leading edge of the wing, centered on a rib, strongest part of the surface.  The wing was caved all the way back to the spar, ~ 2 feet aft.  The deice boot was destroyed and significant trim was required to roll the aircraft back level.  Yeah, a drone would be  a nasty encounter.
