| Résumé | A test was conducted at NASA Icing Research Tunnel (IRT) to evaluate altitude scaling methods for thermal ice protection systems. Two new scaling methods based on Weber number were compared against an existing method based on Reynolds number. The results generally agreed with the previous set of tests conducted in the National Research Council Canada Altitude Icing Wind Tunnel (AIWT) where the three methods of scaling were also tested and compared along with reference (altitude) icing conditions. In those tests, the Weber number-based scaling methods yielded results much closer to those observed at the reference icing conditions than the Reynolds number-based icing conditions. The test in the NASA IRT used a much larger, asymmetric airfoil with an ice protection system that more closely resembled designs used in commercial aircraft. Following the trends observed during the AIWT tests, the Weber number based scaling methods resulted in smaller runback ice than the Reynolds number based scaling, and the ice formed farther upstream. The results show that the new Weber number based scaling methods, particularly the Weber number with water loading scaling, continue to show promise for ice protection system development and evaluation in atmospheric icing tunnels. |
