A '''geodetic airframe''' is a type of construction for the [[airframe]]s of [[aircraft]] developed by [[United Kingdom|British]] aeronautical engineer [[Barnes Wallis]] in the 1930s (who sometimes spelt it "geodesic"). Earlier, it was used by Prof. Schütte for the Schütte Lanz Airship SL 1 in 1909.<ref>{{cite book |last1=Nowarra |first1=Heinz J. |title=Deutsche Luftschiffe: Parseval - Schütte - Lanz - Zeppelin |date=1988 |publisher=Ponzun-Pallas-Verlag |location=Friedberg |isbn=978-3-7909-0332-4 |url=http://docplayer.org/9086308-Sandini-archiv-richlli.html |accessdate=2 December 2018 |language=German}}</ref> It makes use of a [[space frame]] formed from a spirally crossing basket-weave of load-bearing members.<ref name="Buttler93">Buttler, p.93</ref> The principle is that two [[geodesic|geodesic arcs]] can be drawn to intersect on a curving surface (the fuselage) in a manner that the [[Torsion (mechanics)|torsional load]] on each cancels out that on the other.<ref name="Buttler94">Buttler, p.94</ref>
