This work demonstrates static testing of a composite blade W55RBVS structure for the wind turbines of up to 6kW power.The testing consists of the static testing of the structure up to the moment of the blade failure. The main purpose of the testing is to define and directly verify the rigidity of the blade W55RBVS,to determine the maximum force which leads to faliure and the relative span of the blade failure. W55RBVS composite blades, manufactured by the company WING.doo and are installed on a two-blades wind turbine Eoltec Scirocco. This test is defined in the standard IEC 61400-2 I8I. Blade testing is performed in the Aerotechnics Laboratory of the Faculty of Mechanical Engineering, Belgrade University. The load test is performed up to the moment of the blade failure. The result of the testing will be used in order to improve the design of the blade W55RBVS.
