Influence of geometric parameters of leading edge horn-ice on stall characteristics of airfoil

The irregular characteristics and geometric randomness of horn-type ice are significant while the behaviors separation complex. mechanism factor leading to essential change stall performance still not clear. According actual requirements airworthiness certification a large passenger aircraft, family shapes with different parameters constructed based on typical supercritical airfoil icing environment. By combining wind tunnel test numerical simulation methods, parameter sensitivity height angle is systematically analyzed influence shape bubble development under process summarized, which provides theoretical basis for aircraft.
