Lifting Surfaces<br />

Planform Shapes<br />

Planform Shape: The planform shape <strong>of</strong> the wing will<br />

affect<br />

• Lift<br />

• Drag<br />

• Moment<br />

Surface Area: As mentioned earlier, forces and<br />

moments are proportional to.<br />

F ∼ = C L QS<br />

and<br />

M ∼ = C M QSl<br />

Thus<br />

• Larger wings produce more lift and drag<br />

• Larger wings produce more Moment<br />

• More on chord length, l, shortly<br />
