shropshire 0 #26 February 22, 2008 Unmanned would be a good start... but my question is really about deploying a canopy at altitude not thermalling up with and already deployed one.. I'd be interested to know if it can be done and how fast, what forces etc.. Thanks (.)Y(.)

billvon 3,111 #27 February 22, 2008 We had a reserve ride at 25,000 feet at World Team one year. Broke two of the guy's ribs. I had a friend who used to do HAHO's at 30,000 feet with a 200 lb load and (basically) a tandem container. They kept breaking lines, risers etc. They eventually went to an 8' diameter drogue to get enough drag to make the openings manageable. At a high enough altitude, the trim speed of the canopy becomes higher than the speed of sound, and the canopy can no longer fly. Quote Share this post Link to post Share on other sites

CSpenceFLY 1 #31 February 22, 2008 QuoteQuoteive seen some videos of instructors deploying canopies of students who couldnt get stable at around 12k feet. Assuming that exit altitude is between 12-15k, the instructor isnt really giving the student much chance to get stable is he? Unless they where injured etc? Sometimes it just aint going to happen and deployment is the safest option for the student. Quote Share this post Link to post Share on other sites
skypuppy 1 #32 February 23, 2008 slthough had the highest freefall, it was unofficial. I think the official record is a russian at somewhere around 87000 feet. At the same time they did the freefall record, another jumper got out and opened up to establish the highest parachute ride. His space suit malfunctioned and he landed dead in his harness. These jumps were done with round parachutes. There may be some threads in the history and trivia area.If some old guy can do it then obviously it can't be very extreme. Otherwise he'd already be dead. Bruce McConkey 'I thought we were gonna die, and I couldn't think of anyone Quote Share this post Link to post Share on other sites
MikeForsythe 0 #33 February 23, 2008 The 30k deployment problems were solved a few years ago. Pretty standard jump these days in some areas Time and pressure will always show you who a person really is! Quote Share this post Link to post Share on other sites
