Description

technical field [0001] The invention relates to the field of rotor deicing, in particular to a rotor base anti-icing device and a manufacturing method using graphene-doped composite materials. Background technique [0002] Icing has always been a major threat to helicopter flight safety. When the helicopter encounters severe flight conditions such as low temperature, rain and snow, if the liquid water content in the air is high, key components such as the rotor base are at risk of freezing. Ice accumulation on the rotor will change the aerodynamic shape of the rotor, resulting in reduced flight performance, reduced lift, increased drag, and increased fuel consumption. At the same time, it will destroy the balance of the rotor and cause vibration, which is very dangerous for helicopters. Specifically, the lift coefficient of the airfoil decreases and the drag coefficient increases after icing. Ice accumulation destroys the aerodynamic shape of the rotor surface, which in tu...
