|A scientific paper by the inventor of the Aerobie® flying ring: "The most difficult aspect of the design task is that the disc must fly over a wide range of α (angle of attack).... A conventional Frisbee disc partially accomplishes this by employing a thick rim to move the center of lift towards the half-chord. But the price of this rim is a substantial amount of drag. My goal was to reduce drag...." See Adler's diagrams and quantitative analysis of lift slopes, lift coefficients, and downwash angles; read about the inventor's early and unsuccessful design attempts.|
