An airfoil, possibly flapping. This is an addition to a previous patent.
Numbering: Our evidence doesn't show this one having its own unique official patent number, so we show it with a suffix ".2". It may be that this addition did have a number, and we will find it someday. Or maybe they didn't assign cert d'additions their own numbers at this stage. Later, they did. We can document the cert d'addition numbering procedures as we work them out.
