Considering the limits of icing wind tunnels in simulating the SLD(supercooled large droplet) conditions in China

a SLD icing wind tunnel is an urgent realistic problem and its scaled theory needs to be solved. According to the dynamic characteristics and icing mechanism of the supercooled large droplets

six SLD icing scaling laws were proposed with the similarity theory and dimensionless analysis method. Some typical SLD icing conditions were chosen for verifying the SLD scaling law. Based on the FENSAP-ICE software

the ice shapes and other icing parameters were obtained

and also compared for the reliability analysis. Results showed that the coupled approach of impact parameter and ONERA method and the coupled approach of impact parameter and Ruff method had certain superiority and were in good agreement with the reference ice shapes in the test. Besides

the coupled approach of impact parameter and ONERA method was superior to the other methods when the median volumetric diameter was 171 μm.
