VectorBoy 0 #30 October 25, 2002 QuoteSo the smallest canopy landed(successfully...) is still the VX46? I was coming in for a landing on my cobalt a few weeks back, I thought I had cleared the area of traffic pretty good,when out of the corner of my eye I catch Mike Stevens Flying in on Luigis 46, just screamin right by me. I wanted to watch his flare and run out but I was low enough I couldn't fixate on anything other than my flare and runout. Dang I missed it! Mike is a little guy and that wing was still screamin.

cobaltdan 0 #34 October 25, 2002 maybe it could be a new trend: tracking canopies... we could all do flock dives and then when you cut, it could be your pilot and rsl out your main? sincerely, dan ps. to answer some questions: it has never been live jumped (yet), and flying it off the back of a pick up truck shows the c25 to be extremely sensitive, 8" of toggle can 360 it in place. i think eric will just wind up turning it by tilting that giant head of his. for deployment i made a small static line freebag the size of a school kids milk carton. it is to be velcroed to your helmet and then static lined.

AggieDave 6 #38 October 26, 2002 Lets see, I'd load it at about 11.2:1, so can I jump it? I promise if I do I'll follow this sequence: deploy at altitude, do a couple hook turns, riser dives, scream like a little girl and chop it. On a serious note: Do you (anyone) think that the sport will reach a point in which no matter what happens with the technology of the parachute, there will be a size that we can't safely go past?--"When I die, may I be surrounded by scattered chrome and burning gasoline."

pilotdave 0 #39 October 26, 2002 QuoteOn a serious note: Do you (anyone) think that the sport will reach a point in which no matter what happens with the technology of the parachute, there will be a size that we can't safely go past? Airliners can easily have wing loadings of 100 lb/ft^2. For a 200lb jumper, that would require a 2 square foot canopy. A wingsuit must be a lot bigger than that. So, when we're landing heavily loaded wingsuits with wheels, and perhaps encased in an aluminum tube with rigid wings, we could probably get down to 10 square feet of wing area or less. Course you'd be flying a plane but thats a different story. Dave Quote Share this post Link to post Share on other sites
darkvapor 0 #40 October 26, 2002 It's not just about the size, but the lift produced. Sure airliners can heavily load their wings, but they can also keep a high enough lift to support the plane in steady state flight and landing. Only way you can produce enough lift to safely support and land a jumper is to fly fast. If canopy technology can get to a point where it can produce 100 pounds of lift per square foot, then maybe you can fly a 2 square foot parachute.. :) Quote Share this post Link to post Share on other sites
lippy 776 #41 October 26, 2002 A guy at my DZ made himself a 25. It was a model of a design he hoped to implement on a reasonable size (still sub-hundred) canopy. It was deployed from a mister bill, while Jason held onto the risers, and the base of the mister bill held onto the grocery bag the canopy was in. He said it was so much fun he didn't wanna let go in time to dump his 96. Other than that, the smallest I've seen is a Icarus Xtreme 69. The DZO at my old DZ jumped it, but got rid of it b/c 'it had a built in turn'. He was just scared though I got nuthin Quote Share this post Link to post Share on other sites
Sonic 0 #42 October 27, 2002 Quote had a built in turn It was probably the weight of the audible on one side that was causing it When you consider a jet that large will stall at 130 knots, it can wasilt be loaded like that - as long as you can run that quick, so can a canopy ----------------------------------- It's like something out of that twilighty show about that zone Quote Share this post Link to post Share on other sites
cobaltdan 0 #43 October 28, 2002 problem is that as your canopy gets smaller the drag of the pilots body remains the same. it does not scale down with the wing and becomes proportionaly larger. given the same trim a c25 vs a c75 will fly way out in front of the pilot, as the pilot is the largest component of the systems drag. i estimate that a 9 cell cc50 would be about the smallest someone like chuck blue or mikael stevens could repeatedly safely land. i estimate on our xbraced onyx a 40 would be about the limit. with a rigid wing (hang glider) we sucessfully played around with a 33 sq ' glider. such wings are more efficient and you have the benifit of being able to pilot them in a prone low drag position which is not very practical in skydiving. the smallest production hang glider i know of is about 120'. but then again the entire point of gliders is to be able to soar, not simply decend and land. sincerely, dan<><>Daniel Preston <><> atairaerodynamics.com (sport) atairaerospace.com (military) Quote Share this post Link to post Share on other sites
SkymonkeyONE 3 #44 October 28, 2002 Just a not about Mikeal Stevens: He regularly jumps a 53 square foot Xaos, so the 46 was not much of a reach for him. Chuck Quote Share this post Link to post Share on other sites
