Elliptical questions

SO hypothetically, would you say thats it would be bettter or at least possible to learn to swoop under a square or slightly tapered canopy?
SOme of the newer jumpers I know on those faster canopies have no interest in high performance landings but I have to say that the tingly feeling I get when I hear someone swoop is enough for me to realize I'll be learning how (slowly, as safely as possible, and with a coach).



well, I know one of the early versions of the Pond Swoop Nationals was won on a Sabre.... dirt water dirt... it's very possible!

well a smaller canopy will react different that the same canopy in a bigger size.
the wingloading adds speed to the canopy.
There is a really good article by John LeBlanc in the PD website where he explains those efects.
An eliptical wing will be more responsive because of the shape of the wing. an eliptical canopy will turn way faster than a square or a semieliptical.

That panic turn will break a jumper regardless of the type of canopy they are using.


Come on, are you serious? There are quite a few different degrees of being broken.


Then, do you have convincing evidences that a square canopy is more forgiving than an elliptical canopy when it comes to a panic turn?
As a counter-example, for panic turns, a nitro is more forgiving than a sabre, even though it is a high performance elliptical. First, the toggle stroke is much longer, then, after a toggle turn, the minimum recovery arc is shorter. In addition, it is less likely to stall while trying to dig it out of the dive.

While a Safire 300 (yes, we have one) may break an ankle if someone "panic" turns, a VX 120, even at the same wingloading will probably kill someone who "panic" turns.


Well, if you want to compare canopies, it might be a good idea to compare them at same size and and same wing loading (lengths, areas, and volumes don't scale the same way). Compare the likely outcome of someone doing a panic turn under a safire 120 and under a vx 120. Personally, i don't see any obvious difference (the shorter stroke of the vx is balanced by its better efficiency when it comes to dig it out of the dive). Either the vx is underloaded and it is a tame liner, or the safire is overloaded and it is a killer as well.
