An experimental investigation was conducted to study the aerodynamic effect of simulated ice accretion on a wing and horizontal tailplane of an aircraft by means of wind tunnel testing. Ice accretion was simulated by strips of different shapes positioned either ahead of the right aileron or at the stabiliser. The strips of two cross sections were examined, of a V shape section simulating a conventional leading-edge ice accretion and of a quadrantal section with front edge perpendicular to the upper surface of the airfoil simulating an ice accretion caused by supercooled large droplets. Its influence on the basic aerodynamic characteristics of the aircraft was evaluated, i. e. the lift, drag, side force and moments.
