Ascension

We settled on the techtype "ascension" to avoid confusion with other technical associations of the word "elevation". Ascension has specifically to do with "force ascensionelle", or force of ascent. It is naturally not to be confused with lift. Ascension has entirely or nearly entirely to do with vertical propulsion, particularly in the cases of patents in which an innovation does not also pertain to horizontal propulsion. (The French "sustentation", which technically refers specifically to precise maintenance of distance between an object and a surface, almost invariably applies to ascension.)
