Note: This word almost invariably equates with propellers. In France, "propulseur à hélice", Patent FR-1878-127183, was to evolve simply down to propulseur, towards the ends of the period we are studying, though hélice is the current equivalent to our English "propellers". In francophone Belgian material, particularly the later material within our range of interest, the word is used as the equivalent of propulseur, as this latter terms itself came gradually to assume the "blades" and so forth which we associate with propellers. It is over time, in the Belgian context, that "propulseur à hélice" evolved into simply hélice.
(An odd exception to the above, and possibly an exceptional trend, in the francophone usage of France itself, is to be found in Patent FR-1911-426130. In this filing we have hélice used in a manner specifically not related to propulsion. Something which could appear to us as a "propeller" is itself caused to rotate, compelled thereto by wind resistance, faced by an airplane likely set in motion and achieving lift and so forth by other propellers, as such. In this particular instance, said blade rotation, actioned by the air, rather than acting upon it, powers the operation of surfaces oriented towards stability.)
(On a further francophone note, in Patent FR-1914-471027, we have "roues de friction", wheels of friction, that is, likely somewhat similar to the above, though acting here in conjunction with hélices themselves powered by the "roues de friction" and acting upon the air, in the usual manner of propellers, the overall arrangement leading, as it were automatically, stability. In cases such as these propulsion is an entirely separate matter.)
We have at least one rare instance of "hélice" used as rudder.[1]
