Trawl-kite

open access: yes, 2023
Denne bacheloroppgaven utforsker designprosessen for et trål-kitesystem, en spennende fremgang innen marinteknologi. Trål-kite er konseptualisert som et autonomt system med mål om å gjøre bunntråling, en betydelig del av de globale fiskeriene, mer bærekraftig. Dette innovative systemet er utformet som en kite, utstyrt med hydrofoiler for løftgenerering,
