Figure 13.7 A swept wing in sideslip.
where b =2s is the wing span. It is clear that for a wing with dihedral the expression
given by equation (13.92) will always be negative and hence stabilising. On the other
hand, a wing with anhedral will be destabilising.
Wing sweep also makes a significant contribution to L
v
. The lift on a yawed wing is
determined by the component of velocity normal to the quarter chord line in subsonic
flight and normal to the leading edge in supersonic flight. ...
