Sustentation

Technically, etymologically, this has to do specifically with maintenance of a certain distance between an object and a surface, rather than in the increasing of that distance. Its practical overlap with lift is quite preponderant, though not exclusive, and with the exceptions being of excellent per volume intrigue. As a search term, relative to francophone originals, it is extraordinarily handy.

There are also tech field results for “sustention”, which has become an anglophone norm and is a lesser-used word in the francophone sources.

This wiki has 213 patents in category "Sustentation". Other techtypes related to Sustentation: Ascension, Buoyancy, CA 244/8, CA 244/9, Compression, Helicoplane, Lift, Rarefaction, Traction, USPC 244/8, USPC 244/9
