- Overview

  **An overview of aerodynamics of rotors, with emphasis on Horizontal Axis Wind Turbine rotors.**

  Rotor and wake aerodynamics are key to many applications such as helicopter and propeller rotors in transport and wind turbines for electricity generation. But rotors have a tendency to generate three-dimensional unsteady aerodynamic phenomena that are complex both to understand and to model.

  For anyone working in the development and production of helicopter or wind turbine blades, this course is invaluable. It will deliver a depth of knowledge of the science and an ability to apply the technology that will enhance the careers of those already in the industry and the prospects of those wishing to enter it.

  The course focuses on the following topics:

  - Momentum theory applied to rotor simulation and design and potential flow models for rotors
  - Airfoil aerodynamics
  - Unsteady aerodynamics
  - Aeroacoustics
  - Wake aerodynamic

  *Modelling can be carried out in any programming language, for example MATLAB, C, or Python.*
- Details

  To effectively conceptualize and design a rotor, it is necessary to combine the fundamental and modeling perspectives of the rotor. In this course, we provide an overview of the phenomena in the aerodynamics of rotors, with special emphasis on Horizontal Axis Wind Turbine rotors. Propellers, vertical axis (crossflow) wind turbine rotors and helicopter rotors will also be addressed, but in less detail.

  There will be hands on introductions to the different computational models used nowadays to analyze the aerodynamics of rotors, with a focus on vortex models.

  The course includes:

  - An introduction to rotary wing aerodynamics with applications in aircraft, propulsion, fans and wind turbines.
  - A discussion of conservation laws, actuator disk/momentum theory and limitations.
  - An examination of helicopter rotor vertical flight and "windmill brake" state. How to calculate figure of merit.
  - Understanding the Betz optimum for wind turbines and lift and drag devices and the blade element momentum method.
  - "Tip" correction methods, correction for finite number of blades and heavily loaded rotors are examined.
  - The aerodynamic characteristics of airfoils for rotor applications and the properties of pitch and stall controlled wind turbines are explored as a precursor to a wind turbine rotor blade design exercise.
  - There is a study of vortex line methods, vortex wake structure, Frozen and free wakes and vortex core modeling. These are followed by the exploration of vortex panel methods, advanced wake models and the acceleration potential method.
  - Detailed study of rotor near wake structure, experimental wake velocities and wake vorticity structures.
  - Examination of 3D effects, stall delay, yawed flow and dynamic inflow and autogiro and helicopter rotor aerodynamics in forward flight.
  - Unsteady aerodynamics and dynamic stall effects, the effects of tower shadow and wind shear and Theodorsen's Theory.
  - Vertical axis wind turbine rotors and the Voight-Schneider propeller
  - Effects of inflow turbulence intensity on blade loads and near and far wake structure
  - A study of wind farm aerodynamics looking at rotor-wake interaction, single and multiple wakes and the effects on loads and performance.

  ##### Video Lectures and Online Office Hours

  The lectures of this course are broadcasted live online. Live attendance is possible but **not** required - the videos will be available around an hour after the lecture which can be watched later. In addition, there will be online office hours with the instructor on a weekly basis, which are also optional.

  ##### Assignment

  Students will develop and program different aerodynamic models currently used in industry, and apply them to analyse relevant rotor operations.

  ##### Literature and Study Material

  Course lectures - students can download the course lectures, background material and assignments from the accompanying e-learning platform. This e-learning platform will also be used extensively for submitting exercises and response to students.

  Recommended literature - the recommended literature for each chapter will be indicated in the course lectures.

  ##### Assessment

  Continuous assessment through individual online assignments, three group assignments and a final exam via [online Proctoring](https://learningforlife.tudelft.nl/service-contact/taking-exams/).

  Date of proctored exam and resit will be communicated during the course.
- Qualifications

  ##### Certification

  If you successfully complete your online course you will be awarded with a TU Delft certificate.

  This certificate will state that you were registered as a **non-degree-seeking** student at TU Delft and successfully completed the course. The certificate will also indicate the number of ECTS credits this course is equal to (4 ECTS) when this course is taken as part of a degree program at the university.

  This course is a MSc course in the Faculty of Aerospace Engineering. If you decide that you would like to apply to the full Master's program in Aerospace Engineering, you will need to go through the admission process as a regular MSc student. If you are admitted, you can then request an exemption for this course that you completed as a non-degree-seeking student. The Board of Examiners will evaluate your request and will decide whether or not you are exempted.
