Discussion

An engineer sizes a wing using the rigid load distribution rather than the flexible one. The result will be

  • A.Identical to the flexible result
  • B.Conservative only for unswept wings
  • C.Conservative; flexibility sheds load inboard
  • D.Unconservative and unsafe

Answer: C

A swept wing twists nose-down as it bends, shedding lift outboard and reducing the root moment. Ignoring that gives a higher predicted moment and therefore a heavier structure, which is safe but wasteful, and is why flexible distributions are computed routinely.
