Abstract
A blade system of wind-hydropower plants, airscrews/marine propellers or main rotors contains one, two, three or more basic blades located in one plane at angle to the longitudinal axis of each of the blades and in the plane of rotation of said basic blades. For reduction of the torque from trailing-vortex drag of blade the system additionally contains one, two or more sets of blades, which are made with decrease of the length of blade relative to the length of the blade of basic complete set. The number of blades in each of additional complete sets coincides in number with complete set of basic blades and their materials.
