The invention relates to a rotor wing anti-icing and de-icing structure for an aircraft, belongs to the technical field of aircrafts, and solves the problem that a heating wire is easy to fatigue and break in the prior art. The device comprises an electric slip ring, a transmission, an oil pump, a heating cavity and an oil pipe, wherein the anti-rotation rod is sleeved with the electric slip ring, the electric slip ring is located in the rotor wing driving shaft, one end of the electric slip ring is electrically connected with a power source of the aircraft, the other end of the electric slip ring is electrically connected with the heating cavity, and electric energy can be provided for the heating cavity to heat liquid; the transmission is arranged at the top end of the anti-rotation rod, the input end of the transmission is fixedly connected with the propeller hub, and the output end of the transmission is fixedly connected with the oil pump. The oil pump and the heating cavity are arranged above the transmission; an oil path is arranged in the paddle; the oil pipe communicates with the heating cavity and the oil way. The electric slip ring is adopted to introduce a power supply of the aircraft into the heating cavity to heat the liquid, rotation of the propeller hub is utilized to drive the oil pump to feed the heated liquid into the oil duct in the propeller blade, and the oil-way oil pipe is not prone to fatigue fracture.
