“…Ahn et al [34] conducted an experimental study on the engine air intake of a KUH-1 Surion helicopter using an icing wind tunnel to obtain the shape of ice accretion and compared the experimental results with the FENSAP-ICE computational package. Jung et al [35] evaluated the performance of electrothermal anti-icing systems for a rotorcraft engine air intake based on a meta model and presented guidelines for determining the required level of heater power and the size of heat pads.…”
