Simulated ice accretion tests on four sub-scale rotating spinner models with different cone angles were conducted in icing wind tunnel. The similarity parameters of ice accretion were derived for rotating surface. And the ice accretion test parameters for sub-scale spinner models were determined according to the matching of important similarity parameters. The ice accretion and final ice shapes were recorded by a high speed video system in the test. The test results show that the ice accreted on these four models is composed of early formed glaze ice which entirely covers the clean surface and subsequent white rime ice which grows rapidly. For the spinner model with cone angle is no larger than 74°

the rime ice appears in the form of needle or grain

which is relatively thinner. For the spinner model with cone angle larger than 80°

the rime ice is feather shaped which is thicker and could be partly shed from the icing surface. The position of shedding for the spinner model with larger cone angle moves downstream.
