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, as a principle per se, though overlapping applicability cannot be avoided. 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[1][2], almost invariably applies to ascension.

The pertinence of the helicopter and to some hybrids is key, in that this techtype is necessitated largely via propellers used in the direct furtherance of altitude, aside from propulsion, in contradistinction vis-à-vis the airplane's classic use of propellers in the furtherance of forward motion and this acting in conjunction with wings in the achievement of per se lift.
