Also revealing it its way: The achievement by Vickers with their VC-10 wing is not credited, although it was the best of its time. BTW, Figure 8 demonstrates a lack of understanding what drives maximum subsonic lift. I'm not impressed. | |

I interviewed an aerodynamicist from Airbus currently and he talked about the big fight over including variable-camber on the A340 wing (eventually it was not included). The A340 wing was also a competition between Bremen and the HSA team. | |

See this lecture on their A310 design efforts - they depict the airfoil as a natural development of Pearcey's "Peaky" airfoils that were used on the A300: jstor.org/stable/2398246?seq=11#metadata_info_tab_contents | |

Kawalki in Germany when it was found that inverted airfoils performed better at transsonic speed. Also, the A310 wing is based on a design by Airbus Bremen which was proposed after the Hawker Siddeley design for the A310 wing proved to be mediocre. To save face, Hawker Siddeley used the Bremen design and sold it as their own. Next, the US sued Airbus for patent infringement when the A310 came out with its supercritical wing, only to lose the case because of the earlier work by Kawalki. | |
