Editing Delta wing (section)

===Supersonic transport===
{{main article|Supersonic transport}}
When supersonic transport (SST) aircraft were developed, the tailless ogival delta wing was chosen for both the Anglo-French [[Concorde]] and the Soviet [[Tupolev Tu-144]], the Concorde beginning test flights in 1965 and the Tupolev first flying in 1968. While both Concorde and the Tu-144 prototype featured an [[ogival delta]] configuration, production models of the Tu-144 differed by changing to a [[double delta]] wing.<ref name=gordon>Tupolev Tu-144, Gordon, Komissarov and Rigmant 2015, Schiffer Publishing Ltd, {{ISBN|978-0-7643-4894-5}}</ref> The delta wings required these airliners to adopt a higher [[angle of attack]] at low speeds than conventional aircraft; in the case of Concorde, lift was maintained by allowed the formation of large low pressure vortices over the entire upper wing surface.{{sfn|Orlebar|2004|p=44}} Its typical landing speed was {{convert|170|mph|km/h|0}}, considerably higher than subsonic airliners.{{sfn|Schrader|1989|p=84}} Multiple proposed successors, such as the [[Zero Emission Hyper Sonic Transport]] ZEHST), have reportedly adopted a similar configuration to that Concorde's basic design, thus the Delta wing remains a likely candidate for future supersonic civil endeavours.<ref name="Independent">{{Citation | url = https://www.independent.co.uk/travel/news-and-advice/concordes-successor-revealed-at-paris-air-show-2300191.html | title = Concorde's successor revealed at Paris Air Show | newspaper = [[The Independent]] | date = 20 June 2011 | access-date = 21 June 2011 | archive-date = 22 June 2011 | archive-url = https://web.archive.org/web/20110622035456/http://www.independent.co.uk/travel/news-and-advice/concordes-successor-revealed-at-paris-air-show-2300191.html | url-status = live }}</ref>
