2) support it by using the struts. then maintain shape of topside using battons as needed.(The top side will no longer have wind pressure maintaining the shape.)
Something like this was done back in 2003 by Faction Kites :
Back to your Find --GregK--
Looking at the underside and compare to a HG, it Is similar, however with
the double surfacing on the bottom side going to 25%, it represents a Larger
and slower HG. Something used for a Tandem machine. They found that bringing
the bottom back to 100% made a Big difference in the speed range but made the
machine stiffer in handling. My glider is !00% on the bottom but I have Spoilers
to turn it.
The Rogallo wings turn with weight shift so they back off the underside a bit, and
add the Mylar TE . 80% is a good place to terminate the double surface, that
is where mine will go to, then the final single surfacing will be the Mylar. I've flown
lots of HG's with those proportions and they had Really Good performance.
SO --Johnny Rotten-- you said this :
"(The top side will no longer have wind pressure maintaining the shape.)"
There is a few ways to reintroduce the pressure to the underside after Ya double surface it.
There's a LEI tube in the way,so doing it like a PL is out, but Ya could place a scoop
underneath, to suck air in.
It would be Way easier to pressurize it than add a defined airfoil with battens, however
that is the way i wanna do it cause i'm good at composites.
Didn't wanna bring this thread back till After the Mods get test-flown at the lake
Well -- yesterday, (Feb 15) i flew my 2008- 13m Ozone Edge for the Last time !
I looked at Every stretched spot & wrinkle on the sail, and noted what the fabric
looked like just before it's doubled over on the TE, (looked cupped).
Sure Hope i'm NOT screwing up a Perfectly Good kite that someone else Could enjoy ?
Because Today i take scissors to it -- and dive-into my Mods.
Let Ya know if it's Better or if it's Garbage when done, in about Two weeks, (after i test-fly it).
The Mylar TE and the carbon battens are First-Up.
Won't bring this Thread back till i take it boarding again -- with the new Mods. --------promise
