Ok...so how do you calculate the surface area of an irregular shape such as a kite? I can't evenly divide it into two triangles (for the wing tips) and a rectangle (for the middle).BWD wrote:Aspect ratio = ((wing span)^2/surface area)
So a hypothetical 12m kite shaped like a flat rectangle when unrolled, with a 5.4 AR has a span of 9.2m and chord of 1.3m.
Really kites aren't shaped so simply, and other factors are considered but that's the idea.
If you have a 12m kite for example then wouldn't the surface area of the kite be 12m**2 ?Kiteus Maximus wrote:Ok...so how do you calculate the surface area of an irregular shape such as a kite?

I want to measure my kite and determine the aspect ratio is what I am getting at.
Thanks.

Yes, first you need to measure your actual kite size. Meter-number printed on the kite is just marketing.frankm1960 wrote: If you have a 12m kite for example then wouldn't the surface area of the kite be 12m**2 ?
I always assumed that was the case but maybe that number is a measure of something else.
And everyone of those shapes would have a different AR based on what theHansen Aerosports wrote:BWD is correct. Here is an example of some different shapes all having the same AR.
Cheers!
