Before all we have studied the loads applied to the rotor, which allows the knowledge their effect on the fatigue, also studied the rotor with longitudinal crack in order to determine stress, strain and displacement. Firstly we compared the first six modes shapes between cracking and uncracking of HAWT rotor. Secondly we show show evolution of first six natural frequencies with longitudinal crack propagation. Finally we conclude that the residual change in the natural frequencies can be used as in shaft crack diagnosis predictive maintenance. }, journal = {International Journal of Aerospace and Mechanical Engineering}, volume = {8}, number = {12}, year = {2014}, pages = {2097 - 2101}, ee = {https://publications.waset.org/pdf/10000582}, url = {https://publications.waset.org/vol/96}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 96, 2014}, }
