yoink 321 #1 March 21, 2004 hi all, I was watching some kite surfing recently that works on the principle of semi-solid ribs that are inflated in a similar way to that of wingsuits. One of the guys mentioned that the more solid a wing was, the more controlable it was... It led to this thought... (through a couple of beers ) Has anyone tried a wingsuit that is pressurised by external means? Ribs that maintain a high pressure from a small external cylinder of compressed gas. I would have thought that this would make a more rigid wing... I have no idea whether this would be a good thing or not, just that canopy stuff seems to be trying to get as rigid as possible to get extreme flight.

piisfish 140 #2 March 21, 2004 yes... Yves Rossy www.hookturn.net/blazi/Rossy2.jpg some other pics available on the same site... on this pic he just exited (as you can see) and the inflatable part of the wings is inflating (CO2 bottle) he reached 4+ glide ratio AFAIK there is no traditionnal suit that has been infalted artificially. But I know of some home made suits with semi-rigid ribs...scissors beat paper, paper beat rock, rock beat wingsuit - KarlM Quote Share this post Link to post Share on other sites
yoink 321 #3 March 21, 2004 4+?!!! holy crap! that is too cool... I want one! Quote Share this post Link to post Share on other sites
piisfish 140 #4 March 21, 2004 he crossed lake geneva from Evian to Lausanne (16km) exiting at 6000 meters, inflating the wings, control check parallel to the french coast, and then crossed... deployed at 2000 meters... but if you want one, you have to build it for yourself he is now working on a version with a bigger wingspan, and with a small turbine on it (like 10kg thrust) to try and acheive a level flight... Seems he is inventing the human airplane or something...scissors beat paper, paper beat rock, rock beat wingsuit - KarlM Quote Share this post Link to post Share on other sites
billvon 3,090 #5 March 21, 2004 >and with a small turbine on it (like 10kg thrust) At a 4:1 glide he's going to need a lot more than 10kg of thrust. Quote Share this post Link to post Share on other sites
piisfish 140 #6 March 21, 2004 I'M REALLY NOT (oops sorry for shouting) sure about this 10kg, maybe more... certainly more... or was it 40kg... but he's working on it. if you've seen Bruno Brokkens book EXIT, he's several times pictured in there... with this suit, on several skysurfs (a round one, one in a shape of a Mirage fighterplane, himself in a pilot suit, flying his Mirage in front of Bruno fu*ç&%ng close) etc etc...scissors beat paper, paper beat rock, rock beat wingsuit - KarlM Quote Share this post Link to post Share on other sites

base311 0 #9 March 22, 2004 Have you happened to PRICE one of these simjets? Lotsa $$$ and they're also very ornery. Good, but a pain in the butt. Plas how are you going to shield the exhaust to keep it from frying your azz?? Much of the problem with inflatables is the actual manufacturing of the bladders. It's $$$ to own RF welding equip, the technical aspects of heat welding are difficult to overcome for a hobbyist manuf., and solvent welding just doesn't really get the job done as well as RF or heat welding. It can be done, obviously, but it's technically difficult to arrive at a sealed bladder/wingform. That said, I'm currently working on a pressurized design.

Bowie 0 #10 March 22, 2004 I know about the price and the Frying azz problem I work just 500 m from were simjet make the test run on the new engines. But one has to dream once in a whileBo Wienberg vimeo.com/bowienberg Quote Share this post Link to post Share on other sites
kansasskydiver 0 #11 March 22, 2004 Would it kinda be the same as the rigid wing crossing of the English channal? They weren't inflated, rather an actually wing, but the pricipal of that picture looks almost the same<--- See look, pink dolphins DO exist! Quote Share this post Link to post Share on other sites
base311 0 #12 March 22, 2004 Oh yes... certainly one must dream. In fact I believe that if you can dream it, you can have it. So get busy figuring out how to fund, mount and shield the thing. Could be fun. How about some of the High Power Rocketry motors? 'Course... pilots might be a little concerned about carrying an M motor on board. Ground launched.. maybe give Rutan a call. hrmmm. Sounds dangerous... count me in. Gardner Quote Share this post Link to post Share on other sites

Yves Rossy's wing is approx 1 third rigid, 2 thirds inflatable. The shape is also very different.scissors beat paper, paper beat rock, rock beat wingsuit - KarlM Quote Share this post Link to post Share on other sites
Bowie 0 #14 March 22, 2004 Ok now wee are talking about it, where would you put it??? I think it will be too hard to hold it on your foot If you put it on a belly bracket with a 2 ft pylon like on a jet plane will the exhaust burn your leg wing and is one enough how much trust do you needBo Wienberg vimeo.com/bowienberg Quote Share this post Link to post Share on other sites
