Andretti recalled: “The idea came from my experience with the March 701 from 1970. Its sidepods looked like wings. During a test at Kyalami, we removed them to reduce drag. Suddenly the car became light in front.<br />“This showed us that the sidepods were obviously producing downforce. We had to run a lot more wings upfront to compensate, but that thwarted our plan because we wanted to save drag.<br />At the end of the 1976 season, we met at the Lotus factory in Hethel to discuss next year’s car. The engineers [including Colin Chapman] wanted to know what I would like. I told them that as a driver you would like to have downforce without paying a price for it.<br />They laughed and said: Yes, everyone wants that. Then I told them the story of March’s sidepods. They obviously produced downforce without increasing the frontal area of the car. We then discussed it."<br />And the rest is history it could be said. From there the iconic ground-effects Lotus; Andretti continued: “We then optimized the diffuser and the ground clearance for this principle. The two channels in the sidepods have been consistently freed to get a clean flow through the whole car." ... "<br /><br />SO! Peter Wright, who invented those "sidepods" for the March Team and working at Lotus when he developed the ground effect theory is not the father of those ideas, Mario Andretti is! <br /><br />Duh! <br /><br />asperezashttps://www.blogger.com/profile/18103702927470626913noreply@blogger.comtag:blogger.com,1999:blog-2969324406246488500.post-27436271027631518842021-10-02T06:40:20.448+01:002021-10-02T06:40:20.448+01:00Como muitos poderão ter reparado, o Brabham BT46B ...Como muitos poderão ter reparado, o Brabham BT46B "fan car" não foi mencionado. Porque é irrelevante para este artigo em torno das ideias originais para o desenvolvimento de um conceito. O BT46B nada trouxe de novo, não era mais do a versão F1 do Chaparral 2J. Quanto ao Efeito de Solo na F1, ele foi introduzido mais de 18 meses antes no Lotus 78, em finais de 1976.<br />O Chaparral 2J foi proibido após a sua única época na CanAm 1970 e o BT46B "fan car" foi banido após a sua única corrida e vitória na Suécia em 1978, ambos porque as hélices foram consideradas dispositivos aerodinâmicos móveis.asperezashttps://www.blogger.com/profile/18103702927470626913noreply@blogger.comtag:blogger.com,1999:blog-2969324406246488500.post-4933142042157089322021-10-02T06:39:38.874+01:002021-10-02T06:39:38.874+01:00As many could notice, the Brabham BT46B was not me...As many could notice, the Brabham BT46B was not mentioned because it is irrelevant for this this article around the original ideas about the development of a concept. The BT46B brought nothing new, it was nothing else than the F1 version of the Chaparral 2J and ground effect was used in F1 more than 18 months earlier, introduced in Lotus 78 by the end of 1976. Chaparral 2J was outlawed after its only CanAm season of 1970 and the BT46B "fan car" was banned after its only race and victory at Sweden 1978, both considered of having moving aerodynamic devices, the fans.asperezashttps://www.blogger.com/profile/18103702927470626913noreply@blogger.com
