MEE556 Final Examination Announcement

Tuesday, September 1st, 2009

The final examination for MEE556 Aeroelasticity will take place between 0900-1200 on Tuesday 13 October 2009. The examination room will be announced closer to the examination date.

MEE556 Aeroelasticity Coursework

Tuesday, September 1st, 2009

Students can download the following MATLAB m-file for use in the coursework.

Flapping angle MATLAB m-file

Each group must study the flapping stability of a wind turbine blade by analysing the parameter such as the wind speed and the blade natural frequency. A bifurcation diagram should be produced by the end of the project and critical events must be pointed out. The types of steady states we expect to see are stable fixed point, limit cycle oscillations, and divergence.

The coursework is to be submitted by 5PM of Friday 16 October 2009.

Lecture Log MEE556-03

Tuesday, June 23rd, 2009

We finished the lecture on divergence of a lifting surface today. The class example was a uniform wing under torsional load.

This week’s homework can be downloaded here. Aeroelasticity Exercise 3: Divergence of a wing.

Lecture Log MEE211-03 & 04

Monday, June 22nd, 2009

These two lectures are bunched together because we basicaly only went through textbook exercises on Force Systems, FBD and Equilibrium.

Homework for this week are Exercise 2: Part 2: Questions 1 and 2.

Lecture Log MEE211-02

Friday, June 19th, 2009

Again. A bit late. We covered the basics of vector calculation and equilibrium conditions. Basicly, the first part of Lecture 2.

The homework for this week is Exercise 2 – Questions 7 and 8.

UPDATE: Solutions for the homework can be found here – Question 7, Question 8.

Lecture Log MEE556-02

Tuesday, June 16th, 2009

We completed the chapter on control reversal. The class example was a 2D 2-DOF aerofoil (pitch and aileron) model. Derivation of reversal dynamic pressure and speed was shown. Finally, we discussed aileron effectiveness and the relationships between reversal dynamic pressure and divergence dynamic pressure.

Homework for this week can be downloaded here. Aeroelasticity Exercise 2: Control Reversal.

Lecture Log MEE556-01

Saturday, June 6th, 2009

This one too. First lecture on aeroelasticity on Tuesday 02/06/09. We covered the following topics

  • Introduction of aeroelasticity – what is this subject all about
  • Description of static aeroelasticity and its applications, ie. divergence and control reversal
  • Basic technical terms in the field of aeronautics

It was still too early for any homework. Should any student have any question, please add them to the comments that follow.

Lecture Log MEE211-01

Saturday, June 6th, 2009

Better late than never. Here’s the lecture log from the first class of the course.

  • Explained basic terms and definitions
  • Reaction forces on different types of support
  • Free body diagram explanation and examples

Homework

  • Free body diagrams

Should anybody have any questions, please post your comments under this post.
