Description

The aim of this course is to develop an understanding of the dynamics of elastic 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.

Intended learning outcomes

On successful completion of the unit the student will be able to:

  1. Explain and use key terminology, parameters and operational principles used in rotors with focus on dynamics problems,
  2. Formulate equations of motion of rotating blades, extract essential dynamic properties and understand their significance during design and development,
  3. Use and modify selected advanced Modal Analysis methods to interpret and solve rotor dynamics problems, be able to use the blade element theory to formulate rotor blade aeroelastic problems and appreciate corresponding changes in structural responses and stability,
  4. Explain the origins of rotor loads, load filtering effect and their influence on the dynamic rotor design,
  5. Summarize the current vibration and load control research trends in helicopter and wind turbine technology sectors.

Teaching details

Teaching will be delivered through a combination of synchronous and asynchronous sessions, which may include lectures, practical activities supported by drop-in sessions, problem sheets and self-directed exercises.

Assessment Details

100% January timed assessment
