Why does APCO change aspect ratio for different sizes of same wing model?
(Contrary to the mainstream manufacturers who use zooming/scaling, keeping aspect ratio constant)
Indeed it does sound odd.
Why should APCO insist on sizing system which is not popular with other manufacturers?
Let’s see – to every problem there is always more than one solution and probably you can reach the goal either way.
The question is what is more efficient and offers better optimization.
A.R.O. by APCO represents a design philosophy which we believe brings the best results possible to the subject of sizing wings for paragliding/paramotoring
Contrary to most companies that scale/zoom their models up and down to create different sizes, we at Apco believe this is not always the optimal way, so for different sizes we build in different aspect ratio
When APCO designs different sizes of wings, we change the area, span and also aspect ratio
The span of the wing and size are changed by adding or deducting the amount of panels (wing segments). This is In order to not only change the area of the wing, but also the Aspect Ratio (A.R)!
This way we reach a better result as the change in A.R compensates for many other variables.
