mccordia 73 #30 May 16, 2011 So you're saying that driving behind a wide semi truck doesnt give of a much bigger burble than driving behind a bicycle at the same speed? Its simply a much, much larger/wider object, thus larger/wider burble.....And may not be al edumecated and stuff with my 2 years of kitchen training flipping burgers at McDonalds, but its really just about size of the suit/object. Something clearly noticable when flying close range/docked formations...bigger suits are hard to impossible to approach near the hind quarters for docks, as they have a much larger effected area by the burble/wake/turbulance of whatever you want to call it. Whatever happens inside there...and how the vortexes react...no clue.. But when it comes to docking and mega close range flying....for sure...smaller suits are a lot easier to get close to for touching and stuff JC FlyLikeBrick I'm an Athlete?

mccordia 73 #33 May 16, 2011 In simpler terms... By your calculation, a 400 way FS formation doesnt give of a much larger burble than a 2 way? We may 'incorrectly' use the term wake to describe what is actually 'turbulance/burble'. But regardless, on bigger suits, its bigger...and dressing for succes is key....JC FlyLikeBrick I'm an Athlete? Quote Share this post Link to post Share on other sites

mnskydiver688 0 #37 May 17, 2011 Obviously, this is a back and forth argument that will probably have no end, but I do have a couple questions. Do you believe the form drag to be more substantial on the larger suit? Do you believe form drag has an effect on wake turbulence? I do believe a smaller suit that is being flown in a very head high (stall) position would have similar wake turbulence as a larger suit with a more head low angle of attack with the relative wind hitting almost entirely on the leading edge. But what do I know? One more... Have you ever been incorrect?Sky Canyon Wingsuiters Quote Share this post Link to post Share on other sites

mccordia 73 #39 May 17, 2011 QuotePS: Regardless, a larger suit may produce the same amount of turbulence as a smaller suit but it will spread the turbulence over a larger area. As well as the wings with a large/lower wingroot 'guiding/deflecting' the relative wind outward more towards where people are flying (when close). It may not all be the right language for the more tech-savy people, but for sure...its an effect thats there...JC FlyLikeBrick I'm an Athlete? Quote Share this post Link to post Share on other sites

kallend 1,635 #43 May 17, 2011 Quotewouldn't the "shape" of the wake change with different shape of the wing ? No doubt, but the total disturbance will be the same. My exit mass, including rig and 5kg of lead, is 81kg. Falling at a steady fall rate of 30m/sec I impart approx. 810 N.sec of momentum to the atmosphere each second and impart 24,300 joules of energy to the atmosphere. Anyone with an exit weight more than 81kg (and that would be most guys) makes more disturbance than me regardless of what suit they are wearing. Quantum mechanics not required, Newton's 2nd and 3rd laws are all that's needed.... The only sure way to survive a canopy collision is not to have one.

mccordia 73 #47 May 17, 2011 Quote***wouldn't the "shape" of the wake change with different shape of the wing ? No doubt So...if we skip all the 'Id rather go into a gazillion difficult explanations rather than acknowledge what everyone else is talking about, and talk about the practical side of things instead of techno-mumbo jumbo that I think is incorrect' you're actually agreeing... Skipping the tech talk, the 'different oriented/directed' wake of a bigger wingsuit for sure influences those flying close. Especially during tight/docked flying, a smaller suit flown at a higher performance level feeds those around the person a lot 'cleaner' air when close. Regardless if the cause is direction, velocity, size or girth..... Shame the tech always seems to take center stage, while the practical side of things and how it applies to what we do is skimmed or even skipped....JC FlyLikeBrick I'm an Athlete?

PS: I don't need to know the size of your suit, I just need to know the model to know that there are smaller suits.
