What is the highest wingloading?

To add,I think they finally figured out that higher wing loading was not always better



Maybe Dave can help us out here. There is a point beyond which performance deteriorates and more WL is counterproductive. There was some discussion about this a while back, but I haven't seen anything about it in over a year. Of course there are new canopies and new theories, like wearing weights with a larger canopy to get wingload with some actual wing as well.

So at what point does wingloading degrade performance ?



It depends on the canopy. Some perform better at higher loadings than others.

Better for what? Counterproductive to what? Are we assuming, and really this is just a rhetorical question, that everyone who swoops is trying to set a new distance record...either personal or world record?

Wingloading can go up, size of the canopy can go down, but the drag of the human body remains the same, and the line drag of a small canopy will be proportionally larger than that of a bigger canopy. So you really start to mess with your lift to drag ratio with too small of a canopy. To get a quantative analysis of this, hire an aerodynamicist.

There is, but it varies for different canopy designs and I personally believe it varies for canopy sizes as well. For years there was a basic belief that anything over 2.1 or 2.2 on the available X-braced canopys (which at the time was the Xaos 21, Velocity, VX and FX for all practical purposes) was beyond the performance range of that canopy. Fast forward to the past two years. We've seen incredible swoops made on the same canopy designs at wingloadings of 2.4 and 2.5. What I'm saying there is that for the extreme high performance canopy range, we're still trying to figure out what works best. Its pretty much a given at this point though, that a very high wingloading on a very small wing is counter productive for competitive swooping. If you have the skill and simply enjoy an extreme amount of speed (and you're a pilot that can handle jumping that size and wingloading) then go knock yourself out.

On non-Xbraced canopies the story is a bit different. I've jumped everything but the Lightening in PD's line up. I've jumped pretty much all of Icarus' lineup (save the FX and the Neos), same with Aerodyne and some other random canopies and I haven't found one that liked being loaded up all that high.

For me I found that most of the high performance canopies lost their "performance" when I went above 2.0 on them. Some of them freak'n rocked at 1.9 but swooped like crap at 2.1. Some people, however, swear by some of those canopies (like the XF2, the Katana and the Cobalt) loaded up around 2.1.

I have found one truth, however. A Spectre 150 loaded at 1.9:1 doesn't fly for shit, swooping or not.:D

Nope, I meant you Dave. Thanks very much for your detailed answer. I know a few years back it was pretty much gospel that performance was affected at some point, but it hadn't been discussed in a while and much has happened to change the thinking on the subject. Appreciate your input.

Ive seen canopies flown with 3.0+ wingloadings, pretty much anytime someone does a mr. bill. Anyone know of the highest wingloading put on a normally built xbraced canopy during this type of situation? Ive seen the pd video of some factory guys doing it with what I assume are velos.
