Are wings like this practical on jets? Are there any other type of vehicles that could benefit from curved wings?
Answer by Thomas Zerbarini:
The forward swept wing is a design makes an aircraft highly maneuverable. It does so because the wing is incredibly unstable. It requires computer fly by wire technology to allow engineers to fly an aircraft with such a wing. It would be impossible for a forward swept wing aircraft to be controlled solely by human input and hydraulics.
