Calvin19 0 #29 October 5, 2006 i do not have a low opinion of riggers, just a low opinion of some. and by "i dont trust riggers to do my rigging" i meant i like doing my own, not that i dont trust them. and i do my own rigging not because i think they are sketchy, but because i like knowing what is going on. and i enjoy being the only person who can mess things up on my gear. my screws are from a paragliding accident, nothing to do with an opening parachute. and besides, being a certified rigger gives a person nothing save the legal ability to pack an emergency parachute. I have read all the books you have homeslice, and i will never become certified. parachutes are retarded and simple. they are designed that way. are you sure you know exactly how a parachute works? -SPACE- Quote Share this post Link to post Share on other sites

Stumpy 256 #31 October 5, 2006 QuoteIm also designing and building a modifies Paraglider wing. it is combining a kiteboarding kite and a paraglider. bladders and all. I'm genuinely curious - why? Kitesurfing kites are designed how they are for a reason. As kites they are actually hugely inefficient compared to a ram air design. What benefit do you get from moving that type of design to a paragliding environment?Never try to eat more than you can lift Quote Share this post Link to post Share on other sites

Calvin19 0 #33 October 5, 2006 Stumpy, My collapse that put me in a coma for a long time happened because paragliders are not ridged. by adding spanwise high pressure air bladders if only one, and as many cordwise as deemed necessary in testing, one can completely be rid of collapses. the idea here is to not modify the paraglider wing at all, but add inside the cells high pressure ait bladders identical to inflatablekites, the wing would perform the same, only wouldnt collapse. this would have saved me from 3 months in the hospital and a lifelong limp. I also kiteboard, so i do know quite a bit about fabric foils, ramair or not. I have also designedand built well-flying and still flying ridged hang gliders, rogallo an not. I actualy rigged up the wing i designed and built when iwas 18 just yesterday to see if i needed any parts so i can do a cutaway from it in moab. this design also could reduce the amount of suspension lines the paraglider needs to keep its shape. actulay, the work iam doing right now is adding bladders to a 1993 mirage glider. all testing will be done on the gliders i have like this. eventualy i plan on doing it to my GIN bonanza. the glider that i crashed. -SPACE- Quote Share this post Link to post Share on other sites

A wing has a dominating force direction (IE kite lines, jumper, pilot) the air flowing over this wing (foil) is seperated over the topskin and the bottom skin. in some of these foils, such as Bladder kites, have a single surface. this only makes the airfoil less efficient. the air flowing over the top of said foil is changed direction in a fashion that it produces a force of its own (this dynamic displacement is called bernouli effect) now, being that the angle of attack of this foil is situated to a point where the lift vector is at an angle forward of the dominating force direction. (forward) the foils or wing is accelerated forward and creates more or less lift so that PARACITE drag and INDUCED drag and the dominating force (sometimes called gravity) are equalised. this, essentialy, is how all gliders work. my goal in this is to make these wings safer, the harnesses safer, for ME. not argue with some 30year master rigger about how much him or I know about aerodynamics. -SPACE- Quote Share this post Link to post Share on other sites Calvin19 0 #47 October 6, 2006 i had no idea bladders were tested, could you point me in a right direction to look at the test results? or maybe they found something that wasnt worth it. please elaborate. websites? and im not questioning the usefulness of reserves in place, but being a skydiver and BASE jumper, i want something a bit more, um, controlable. -SPACE- Quote Share this post Link to post Share on other sites mjosparky 3 #48 October 6, 2006 Quotemy goal in this is to make these wings safer, the harnesses safer, for ME. not argue with some 30year master rigger about how much him or I know about aerodynamics.

As I said before, be real careful.My idea of a fair fight is clubbing baby seals Quote Share this post Link to post Share on other sites
Calvin19 0 #49 October 6, 2006 sorry, senior rigger. and your avatar says 30 years. my bad. my coma was caused by a launch collapse on an alpine launch site from a wind downdraft. i was flying with other pilots at that time at the same site, just, the bubble hit me that day. and im ok with that. -SPACE- Quote Share this post Link to post Share on other sites
