| Abstract | The performance of a 22-inch diameter rotor blade under icing conditions has been investigated using a dedicated test rig installed in a cold room at the Montreal Road campus of the NRC. Tests have been performed to examine the sensitivity of rotor thrust, torque and power to a series of icing conditions ranging from typical civil aviation icing environments (e.g., Appendix C of 14 CFR Part 25) up to those experienced in freezing drizzle precipitation. It has been shown that performance degradation is more pronounced for ice accretions formed from clouds containing smaller Median Volumetric Diameters (MVD) and higher liquid water contents (LWC). It was also shown that ice accretions formed at warmer temperatures (glaze ice) resulted in more rapid performance degradation when compared to those at colder conditions (rime ice). |
