This takes the "plumes" found in the wings and so forth found in Patent FR-1909-403985‎ and Patent FR-1909-404484 and applies them more specifically to wheels. This gets complicated, in that, though this Patent FR-1909-404954 is classified as FR 10.1, which classification having to do with voitures, Plaisant is more generally working with wheels included within the ends of propeller blades. This Patent FR-1909-404954 itself features content and diagrams having greatly to do with aviation. Patent FR-1909-404484 is not properly represented on Espacenet. We found it by way of the reference found within this Patent FR-1909-404954.
