I was also thinking about the speed vs drag issue -- if a certain trailing angle works at a low speed, then it might be too steep for a higher speed? The atmospheric pressure can push air at a certain rate, and given a little longer time (i.e. at a lower speed) then wouldn't a steeper trailing angle work just as well at low(er) speeds?
In other words, is there a specific speed used to develope this ideal profile?
