A series of wind-tunnel tests on a NACA 0012 airfoil was conducted to simulate the aerodynamic effects of runback ice. The drag and lift effects on the airfoil were assessed using wind-tunnel balance for three geometries of triangular section ice shapes at three different chordal positions. The results show a great degree of sensitivity of the aerodynamic flow characteristics to the shape and the chordal position of the ice accretion, and thereby highlight the need for realistic prediction models for runback ice.
