Patent BE-1916-275531
"L’appareil se compose d’une nacelle pourvue d’un couvercle au-dessus duquel est placée une hélice horizontale ; des hélices verticales sont disposées à l’avant et à l’arrière et un gouvernail se trouve sous la nacelle."
That is,
"The apparatus is composed of a nacelle provided with a cover above which is situated a horizontal propeller ; vertical propellers are arrayed in front of and at the rear and a rudder is situated under the nacelle."
Regarding the title, per se, "Navire aérien plus lourd que l’air", we have here a helicopter described as an "airship heavier-than-air". It is also the type of two-prop propeller which seems to have played a role in later Belgian contributions.
This "airship heavier-than-air" (long helicopter of two separate and separately axled propellers of lift) could be seen as a precursor to Patent BE-1926-338559 and to developments alleged to follow later from Belgian foundational work on the helicopter.
As always, it is a matter of Belgian francophone usage that "hélice"(blade) is meant to signify actually the arrangement of multiple blades which we'd called the propeller. The Belgian hélice is the otherwise French propulseur, in the usage we see on antique documents. Hélice, fairly peculiarly Belgian, within the antique material, seems to have become the globally dominant francophone usage, for "propeller", as we generally think of it, aeronautically and otherwise.
