Please tick all that apply. 1. Read the Powerpoint notes. 2. Wrote down the notes on paper to see if you agreed with the logic 3. Read the textbook 4. Tried the examples in the Solved Problems library 5. Solved old tests given by the instructor 6. Asked friends Question Title * 2. Please list the top 5 concepts that you learned in this module. 1. 2. 3. 4. 5. Question Title * 3. What concepts pose(d) difficulties for you? Please discuss, and also how you solved the difficulty if you did. Question Title * 4. Explain as to a 6th grader, how a vortex sheet can be used to represent the effect of an airfoil on the flow. Especially explain the concept of varying vortex sheet strength along the sheet. What is the relation between the velocity values on either side of the sheet? Question Title * 5. Why do you need a vortex sheet to represent an airfoil? Why not a single vortex, or just a line of sources and sinks? Question Title * 6. Explain the fundamental equation of thin airfoil theory. Question Title * 7. Why do we solve the "fundamental equation of thin airfoil theory"? Why not the Laplace equation, which is what describes potential flow? How do you reconcile this mystery? Question Title * 8. Why does it make sense to transform coordinates from chordwise distance to the angle theta to solve the equation of thin airfoil theory? Question Title * 9. Describe in words how, given the equation to the camber line of an airfoil, and the angle of attack, you would proceed to determine all the coefficients of the Fourier series representing the vortex sheet strength. Question Title * 10. Why is thin airfoil theory insufficient to derive the details of the flow around the leading edge of an airfoil? Done
