If you're serious about FIKI
If you're truly serious about an EAB aircraft for FIKI, get LEWICE (a free program that predicts ice shapes). The shape, size and location of the ice are airfoil and airspeed dependent, as the stagnation point moves. In fact, the Roselawn, IN ATR icing fatal accident is thought to have been caused by a configuration change (raising the flaps after collecting ice at a lower speed with the flaps down). There are basically 2 types of ice protection systems: de-ice and anti-ice, with some of the following pros and cons.
De-ice: Ice has to build a little first. All of it may not shed at the same time (or on the same cycle). Cheaper, easier, and less power is needed. Runback is (normally) not an issue.
Anti-ice: Aerodynamics are not affected (unless there is a failure are if runback is an issue). Consumes more power. System complexity is higher. Engine power might be an issue (you may still need to keep the ice off the airplane at lower power settings). Runback could be an issue.
Within de-ice there are pneumatic boot and thumper (electro-expulsive) systems, and within anti-ice there are hot and wet systems. A wet system is simply weeping alcohol out the leading edges. Wet has been around a long time, but it is heavy, complex and leaves the airplane very dirty. But, it is making a comeback due to its lack of failure modes (no residual/inter-cycle ice) and no runback).
Actually, a promising technology that is on the horizon is a material that doesn't collect ice!
