I'd move the interface a bit further away from the blades - why would you refine the mesh between blade and interface for no overall benefit? Look at the nonconformal guidelines in Help (or on here/Learning) for recommended size change limits. 

Check the boundary setting in the second mesh - have you defined the interface as wall & inflated it? Then check all local size settings.
