Ice Accretion Analysis for the Development of the HeatCoat™ Electrothermal Ice Protection System

摘要

Aircraft ice accretion poses real challenges in the commercial and military aviation world. Significant work is required to certify an aircraft in icing, and often ice protection systems are required to minimize aerodynamic impact of ice. Models and simulations are a primary analysis tool used in these efforts. Numerous tools exist for evaluating 2D and 3D ice shapes, but each have benefits and detriments. In this study, ANSYS FENSAP-ICE was used to assess ice growth on a complex 3-dimensional aircraft inlet. The results are compared to a 3-dimensional scan of the ice shape and show good agreement after model calibration. Additionally, a sensitivity study was performed to assess how the ice shape might be altered by relatively minor changes in experimental conditions or by numerical settings in the modeling.
