In the December issue of AOPA Pilot, there is an article on page 97 talking about banner towing. In the middle column of page 98, the article notes that the Aerial Sign Company has many mods it makes to its aircraft to improve their performance, presumably at the low end of the speed scales given the nature of their business.
One mod is the installation of a "gurney flap", which is described as "a thin strip of metal affixed perpendicularly to the trailing edge of the wings". The company's manager refers to the gurney flap as "one of the most fantastic aerodynamic devices that has been placed on airplanes".
Does anybody here know anything about gurney flaps? In other words, does anbody know just what the mod is, and what it does for an aircraft to improve its handling, performance, efficiency, etc., and how it does that aerodynamically.
In other words, how does a thin strip of metal apparently trailing from the wings become one of the most fantastic aerodynamic devices around? I sorta thought the canards are pretty fantastic, too.
Wadda ya think?
