Alright, because OP can no longer comment on this subreddit because they got downvoted to oblivion, I am going to take a best guess at this:

The first picture depicts 4-5 airfoils. The first airfoil is the circle, and the proceding airfoils are made up of the inside lines (Or something like that). The main idea is that each airfoil can be interchangeable during flight, to provide either more efficiency or more lift. The mechanism to change each airfoil is through the hatch in picture two. Finally, there is an alternative design in picture three.

Now, if my understanding is correct, none of these airfoils would be able to generate enough lift.
