Optimization of composite material de-icing component for helicopter rotor

An optimization for helicopter rotor composite material de-icing component based on numerical simulation was proposed. Due to the influence of external flow filed and wire pattern in the de-icing component, uneven distribution of the temperature field on the iron surface of the rotor composite material de-icing component becomes the main factor affecting the efficiency of de-icing. The heat transfer numerical simulation model of the rotor composite material de-icing component was established for de-icing structure optimization. The optimization procedure was determined by using orthogonal test method combined with numerical simulation method. The optimized temperature field distribution on the iron surface of the composite material de-icing component meets the de-icing requirements which reaching 2°C which above zero.
