Previously, TAICE was already validated for icing cases due to water droplets only. In addition, in the framework of High Altitude Ice Crystals (HAIC) FP7 European project, mixed phase ice accretion prediction capability has been added to TAICE. Up to now, Turkish Aerospace Industries (TAI) has implemented models related to ice crystal accretion calculation. Drag coefficient prediction, heat transfer & phase change, impingement, erosion and accretion models are among these models. Moreover, extended Messinger model has been modified for mixed phase icing conditions and are used in this study. Validations of the generated tool have been performed before by using COX and NASA-NRC wind tunnel results. Numerical comparison results on representative pitot probe and engine inlet are given to show capability of the tool.
