bmcd308 0 #1 June 14, 2004 When I hear about lines breaking below the cascades, it always makes me wonder why the cascades are there in the first place. Does anyone know if there is an advantage other than pack volume to having cascades? Would a reserve with continuous dacron lines be so big that no one would buy it? I would think that using dacron instead of more modern materials on a reserve would allow some stretch in overspeed situations, and if the lines were continuous more of them could break and leave a somewhat controllable assembly behind. Other than the resulting giant rigs, what other problems might there be with such a design?

PhreeZone 20 #3 June 14, 2004 Lower cost also. Not having to buy the extra line's save a few bucks per canopy. Over the course of a few hundred canopies thats hundreds or thousands of dollars that the company saved.Yesterday is history And tomorrow is a mystery Parachutemanuals.com Quote Share this post Link to post Share on other sites

billbooth 10 #6 June 15, 2004 Vector Tandem reserves have continuous lines also. It is bulkier, but stronger. Also, if you break one "lower" line, you only lose the support of one line, not 2, as with cascaded canopies. The brake lines are continuous too, for the same reason. I didn't want to sacrifice safety for less bulk on "public transportation". Quote Share this post Link to post Share on other sites

Over the course of a few hundred canopies thats hundreds or thousands of dollars that the company saved. The amount saved on a few yards per canopy is quickly eaten up in the labor costs involved in producing the cascaded lines.

dbattman 0 #10 June 15, 2004 Cascaded lines got rid of pack volume back when the suspension lines were the size of shoelaces. Just one reason. Quote Share this post Link to post Share on other sites
