I'm trying to come up with alternate versions of flight for a new animal species. Wikipedia has this to say: "Powered flight has evolved only four times (first in insects, then in pterosaurs, birds and bats). It uses muscular power to generate aerodynamic forces and to replace energy lost to drag. Flapping: moving wings to produce lift and thrust."
What are some wing design ideas that could be completely different from "dragon," "leather," "feathered," or "bug" wings?
