<strong>Investigation</strong> <strong>of</strong> <strong>Transonic</strong> <strong>Drag</strong> <strong>Computations</strong> <strong>in</strong> APAS<br />
The properties that APAS requires to create w<strong>in</strong>gs were found us<strong>in</strong>g the<br />
spreadsheets shown <strong>in</strong> Figures 7 and 8. APAS requires S, AR, taper ratio, sweep angle,<br />
and dihedral. Both w<strong>in</strong>gs had taper ratios <strong>of</strong> 0.2 and zero dihedral. The most important<br />
output here is the mean aerodynamic chord, which is difficult to calculate by hand.<br />
