Why The “Flight Rings” On A Disc Matter

February 4, 2015 by in Livewire, News with 0 comments

It’s not just for grip. From Wired Magazine:

In 1955 [Walter Morrison] sold his [frisbee] invention to Wham-O—manufacturer of slingshots and Hula-Hoops—where a product designer named Ed Headrick made the final tweak of rippling the top with concentric ridges. These add turbulence, which holds air against the surface for a longer flight.

Engineers have since validated those design choices.
