The invention belongs to the field of rotor blade anti-icing/de-icing design, and provides a rotor blade icing aerodynamic characteristic evaluation method, an electronic product and a storage device.According to the rotor blade icing aerodynamic characteristic evaluation method, the electronic product and the storage device, the cloud and mist icing environment, blade flow field characteristics,blade water drop impact characteristics, blade icing parameter influence and other factors of a helicopter are by comprehensively considered. The method comprises the following steps of: evaluating the aerodynamic environment of the profile of a rotor blade based on the flight envelope of the helicopter; taking the icing core influence parameter of the rotor blade as an icing condition, executingan icing analysis method, and determining a blade icing core influence water drop diameter; and taking the blade icing core influence water drop diameter as an icing condition, solving the ice type of the blade by adopting the icing analysis method, and determining the ice prevention and removal protection range of the blade based on the ice type of the blade. A basis is provided for the controlrate design of a blade heating assembly, so that the combat capability of the helicopter in a complex cloud and mist icing environment is improved.
