(This "R. Pohl" is "Robert Pohl" whom we have as filing also in GB and FR.)

"Les ailes sont formées d’une matière non rigide."

That is, "The wings are formed from a non-rigid material".

("hélice", and "aile", are used in peculiar conjunction here, suggesting propellers, wings, or possibly flapping. Our material on his contemporaneous filings in Britain and France suggest flexible, and inflatable, blades for propellers used on airships.)
