Keel

From Inventing aviation
Jump to navigation Jump to search

The keel is the bottom-most longitudinal structural element on a vessel.[1] The French carène is related to this, as is the French quille, and these relations get semi-complicated in applied usage. Carène may be defined as the "ensemble des œuvres vives d’un navire, quille et flancs, jusqu’à fleur d’eau"[2] (that is, "set of lively (or structurally crucial) works of a ship, keel and flanks, up to the water's bloom"). Here we have "keel" neatly equivalent to the French quille (which also comes up in our data), but some of our internationally cross-referenced patent-discovered usage has the French carène equalling the English "keel", and some external usage has carène treated as fundamentally designating quille[3], and "quille" is defined as the lowermost part of a boat[4].

(As applied to aviation, these terms come up fairly significantly within our data.)

The above usages, in terms of the per se nautical word being applied to aviation, happen variably, and the importation of the word is only rarely explicated, as in , "The addition of the new part, which greatly resembles the keel of a ship, is expected to be a great aid in flying against the wind, as it has a tendency to cut through the air like a knife and to increase the efficiency of the rudders, which it also protects.",[5].
