Abstract:
Icing wind tunnel test method on a hot air anti-icing system was developed based on a transport aircraft wing section. A hybrid wing model equipped with a hot-air ice protection system was tested at the FL-61 icing wind tunnel in AVIC ARI for a range of conditions representative of in-flight icing. Icing wind tunnel repeatability, dry air performance and wet air performance were researched. Test results showed the hot air anti-icing system performed a s a fully evaporated system without running back water, and surface temperature was documented, the maximum temperature repeatability variation was 2.1℃ at dry condition and 3.8℃ at wet condition which represented a good icing wind tunnel repeatability. Wet test cases resulted in significantly lower skin temperatures compared to dry test cases, the maximum temperature variation was 18.3℃.
