The aim of this course is to develop an understanding of the dynamics of blades and rotors in the context of helicopter and wind turbine technologies. Students will be shown mixture of analytical, numerical and experimental methods for rotor and blade analyses. The theories developed for helicopters will be adapted to wind turbine rotors, highlighting the differences and similarities in their dynamics.
On successful completion of the unit the student will: - understand key terminology, parameters and operational principles used in helicopter and wind turbine rotors with particular focus on dynamics problems, - be able to formulate equations of motion of rigid and elastic rotating blades, extract essential dynamic properties and understand their significance during design, development and structural assessment, - be able to use selected analytical and experimental methods based on Modal Analysis to interpret and tackle dynamics and vibration problems, - be able to use the blade element theory to formulate rotor blade aeroelastic problems and appreciate corresponding changes in structural responses and stability, - understand the mechanical filtering effect in helicopter and wind turbine rotors and its influence on the structural loads and vibrations, - be able to approach and understand the importance of the current vibration and load control research efforts in helicopter and wind turbine technology sectors.
