  • apply basic engineering models for wind speed, its distribution in time and space and determine the annual energy production for a wind turbine at a given location
  • analyse measured data for a wind field and determine the mean wind speed and turbulence properties
  • account for the configuration of a wind turbine and the background for the modern three-bladed wind turbine
  • carry out calculations of thrust and power for a wind turbine
  • determine drag and lift for a segment on the blade
  • apply simple beam formulae for calculation of sectional forces and natural frequency
  • describe and calculate the stiffness properties of composite materials applied in wind turbine blades
  • account for the main generator types and carry out simple calculations for their operation
  • describe the difference between AC and DC power and the mechanical-electrical coupling of rotor and grid
