In this research, the wind turbine blade of 0.5 Kw was studied to improve its internal resistance under impact. This thesis was based on the problem of wind turbine blade breakages, due both to bird impacts and strong winds. During breakages, blade parts thrown at speed from the rotating turbine pose a significant risk to residents. This research aimed to improve the design of the blades, to improve the blade impact resistance and reduce risk to turbine users. This was desired wthout modifying the airfoil profile, weight, balance, and without significantly modifying construction methods. Two improved designs were investigated, with metal plate and with steel wire, over the full length of the blade. A new experimental test rig was designed to carry out 3 tests to analyse the new blade designs and compare them with the original design. The three tests performed were bending, lateral impact...
