sid 1 #1 July 21, 2008 I put a test jump on a 1990 accuracy canopy the other day and the Poynter's info seems a little fuzzy, or not completely compatible with the label. Anyone have any info or experience with Quantum Parachute products...... see the vidcap attachedPete Draper, Just because my life plan is written on the back of a Hooter's Napkin, it's still a life plan.... right?

matthewcline 0 #2 July 21, 2008 That design looks like a Test model for the Forestry Services Smoke Jumper Canopy (or one of the many they use) I say this because of the triple chambers on cells 2 and 6.

sid 1 #3 July 21, 2008 that may well be how it started out.... it was manufactured by Quantum in 1990 (I think Bill Gargano?) but the label doesn't say the size (it handles like a 240?) and I was curious about the triple cells on 2 & 6..........Pete Draper, Just because my life plan is written on the back of a Hooter's Napkin, it's still a life plan.... right?

Yes, Gargano designed that, and [the smoke jumper version] is called the Trilobe, and is 300 something square feet. We did some work for the smoke jumpers on theirs. http://www.pcprg.com/smkifp.htm There are some links to pictures there. Quote Share this post Link to post Share on other sites
JohnRich 4 #5 July 21, 2008 It looks sort of like the "Aqutron", which was built like that. The Aqutron was trapezoidal in shape - in other words, the front end was less wide than the back end, so it looked pigeon-toed. They were quite popular for a while for accuracy. I had one and made about 700 jumps on it. It's still in the closet and still serviceable. And yes, they were also used by smoke-jumpers. The one in your photo doesn't have cells as tall and fat as the Aqutron though, so it must be some more modern version. Attached: 1) 1986 advertisement, showing 5-cell version. 2) Photo of mine, the 7-cell version. Quote Share this post Link to post Share on other sites

JohnRich 4 #10 July 22, 2008 Quotewhat exactly is the purpose of the three chambers in cells 2 & 6? I don't know what the official explanation is. But it does give sort of an extra cell; turning a 7-cell canopy into an 8-cell, without any extra lines. In other words, it adds surface area, without the extra bulk of more lines. It does get confusing when packing though, as that extra chamber in the middle kind of sticks out above all the others. And note that some of the new fancy cross-braced canopies have three chambers per cell. Those diagonal cross-braces do a better job of supporting the middle chamber, so that it doesn't bulge upward.

matthewcline 0 #12 July 22, 2008 A few years ago I talked to a fellow at the Alaska BLM who said the extra chambers helped in turbulance. Some thing they had a lot of experience with given where they landed for work. I do not know how valid that point is though. MattAn Instructors first concern is student safety.

sid 1 #17 July 24, 2008 Jerry, I've never seen a canopy with this feature before (but that doesn't mean much) - I pro-packed it for the jump and didn't even notice.. it was only when Dude flat packed it and I saw him scratching his head that we went back to the video and noticed this feature.

I recall a big way way at the Herd SkyVan Boogie, maybe in '77, when he and I left side by side, hand in hand, and tracked down to the skydive .. He steered us into our slots, grins all around,,, and it was a good time.......there were 3 or 4 skyvans flying that Day...Limerick Pa and/or new hanover pa. long time ago.. anyway next time you see him.... please tell Him jimmy said hello... j t Quote Share this post Link to post Share on other sites

Strongs 'Set' 400 and 366 mains have these triple cells on the 1st and 9th cell, they also have no crossports and are hunks of junk!

PeteS 0 #22 July 25, 2008 I worked for Quantum Parachutes for five years, I should be able to give a little confusion to this thread. First, I can't tell exactly what model is in your pic. because of the wide angle. The purpose of the three chambered cells on #'s 2 and 6 is what Bill Gargano calls "Dual centers of pressure". He has had a patent on this cell arrangement. It helps with providing spanwise tension on the center cells, giving a "cleaner" airfoil. they also give two balance points for airflow, providing stability. Bill has always been a forward thinker and one of the best friends you could hope for in life. Quote Share this post Link to post Share on other sites
pms07 3 #23 July 25, 2008 I'm sure that's a Gargano design though am not familiar with that particular model. I owned 3 of Bill's canopies back in the 80s and jumped many others...including the Accutron. Anyone know where Bill is now? pms Quote Share this post Link to post Share on other sites
hajnalka 0 #24 July 25, 2008 Actually the Strong SETs (400s, anyway) have the 3-chambered cells at 1, 2, 8 & 9. No comment on your editorial comment on the canopies , but man I wish they'd at least get a hot knife. Quote Share this post Link to post Share on other sites
rhys 0 #25 July 25, 2008 That's right they do too. you would think ted could afford a hot knife by now. "When the power of love overcomes the love of power, then the world will see peace." - 'Jimi' Hendrix Quote Share this post Link to post Share on other sites
