HW 3: Improved Aerodynamic Analysis<

Airfoils: you need to do the airfoil batch analysis before you can do the wing analysis. Type 1. Make sure to run a wide range of angles of attack and Reynolds numbers.

-

Wing: I prefer type 2, but you could do type 1. Either way you’ll have to iterate on angle of attack. Either to find the right speed for a fixed lift (when running type 2), or to find the right lift for a fixed speed (when running type 1). Make sure to choose a viscous option, enter the mass under inertia, and set your atmospheric properties. When iterating on angle of attack it’ll be helpful to run coarse at first (say every degree or two), then narrow it down and run a finer resolution (like every 0.1 degrees).

Wing: For Polar Type I prefer type 2 in this case, but you could do type 1. Either way you’ll have to iterate on angle of attack. Either to find the right speed for a fixed lift (when running type 2), or to find the right lift for a fixed speed (when running type 1). Select VLM1 as the Analysis type. Make sure to choose a viscous option. Enter the mass under inertia, and set your atmospheric properties. When iterating on angle of attack it’ll be helpful to run coarse at first (say every degree or two), then narrow it down and run a finer resolution (like every 0.1 degrees).

Report the inviscid induced drag (ICD in XFLR5, you’ll need to unnormalize), and viscous drag (VCD, this also includes viscous lift-dependent drag). Compare to your estimates from part 1.
