Using electric heating to protect engine input elements from icing

The ice protection system is a key element ensuring the aircraft safety. Various anti-icing systems are analyzed as applied to specific configurations of aircraft engines. The droplet formation areas on the blade surface are determined, and the coefficients of droplet capture are calculated. A mathematical model of the electrical ice protection system for a given engine configuration is developed, and the required heating power is calculated. It is proposed to apply a combined anti-icing system including the permanent heating of the blade leading edge and the cyclic heating of the rest of the blade. According to the study, a hydrophobic coating is recommended to be used since the device for heating the blade tail is complicated. These solutions can significantly reduce the power taken from the engine.
