Current production helicopter rotor icing protection systems and most systems now under development use electrothermal deicing. This paper reviews other types of rotor icing protection systems for which interest has been shown. In searching for icing protection systems that weigh and cost less than the electrothermal deicing method, investigators have looked at fluid anti‐icing, pneumatic deicing, electro‐impulse deicing, and electro‐vibratory deicing methods. Several of these alternative blade icing protection systems show promise for future development.
