Photos of models to illustrate how washout and billow contribute to the net geometric anhedral of a swept wing

This page last updated August 27 2004

*Note that in many of these photos, each wing panel has been rotated in a way that uses the aft-swept leading edge as a "hinge line".

Model of wing with anhedral

Wing originally flat, trailing edge raised, creates net geometric anhedral, keel horizontal, side view

Wing originally flat, trailing edge raised, creates net geometric anhedral, mean chord line horizontal, side view

Wing originally flat, trailing edge raised, creates net geometric anhedral, mean chord line horizontal, head-on view

Wing originally flat, trailing edge raised, outer panels only, creates net geometric anhedral, keel horizontal, head-on view

Model of wing with dihedral

Wing originally flat, trailing edge lowered, creates net geometric dihedral, mean chord line horizontal, side view

Wing originally flat, trailing edge lowered, creates net geometric dihedral, mean chord line horizontal, head-on view
