CanopyPiloting 0 #51 January 24, 2005 Icarus NZ will have a JVX and JSX (45 cell with NZ bracing) at the 2nd World Cup of Canopy Piloting in Febuary. Jim was jumping the 45 cell JSX prototype with new NZ bracing last year. The JVX and next generation JSX are two of the newest designs from Icarus NZ (Icarus High Performance Division).

skydiverek 55 #52 January 29, 2005 QuoteAnother upside-down rig is manufactured in Eastern Europe (Poland?) for the military market. It seems that communist military freefallers like to attach drogues to the scruffs of their necks, and that configuration works better if the main is on top. I think that's the one made in Poland: http://www.air-pol.com.pl/english/parachutes/ad-2000.html Plus, Poland is not communits anymore - that has changed 15 years ago ! About new Sigma - RWS had a ripcord prototype that included ripcord cable made of 1000lb. Spectra, rather than metal. Sigma will also incorporate larger transparent reserve flap window and a large transparent main flap window. The latter will include a drawn diagram that you can use to check if the loop is routed correctly. Kind of like putting a template on top and making sure everything follows a template.

Unless it goes up into the yoke or they slightly changed where the collins laynard sits, you'll still have to pop the flap to check the routing of the cutaway cable. QuoteRWS had a ripcord prototype that included ripcord cable made of 1000lb. Spectra, rather than metal. On the main or reserve? The main (drogue release) has been spectre before with a straight closing pin on the "end" of the two lines.--"When I die, may I be surrounded by scattered chrome and burning gasoline."

skydiverek 55 #54 January 30, 2005 QuoteUnless it goes up into the yoke or they slightly changed where the collins laynard sits, you'll still have to pop the flap to check the routing of the cutaway cable. The template on the transparent window refers to the main pin cover, not reserve. Also, 100% of the main and reserve pin cover flaps area will be transparent (unlike on previous Sigmas, where only about 15% of reserve pin cover area was transparent). The RESERVE ripcord cable was a blue, slippery 1000lb, spectra line. Bill Booth said that it reduces friction and it will be introduced on Sigma first. After few years he may put it on V3.

mark 102 #58 January 31, 2005 Quote...reserve ripcords made of suspension line back in the 1970s... E.g. the Spanish Fly (more interesting for its internal hardware). The dacron ripcord ran through a fabric channel to a straight pin more commonly used on pull-outs. Most dacron suspension line is more than adequate to meet the 300#/3-second ripcord strength test. 1000# Spectra seems like overkill at first, but given the short length there's no great benefit to using a lighter weight, and the heavier weight should take more abuse before failing. Also, I doubt folks would trust a skinny 525# micro-line ripcord even if it were TSO'd. I'd like to be able to extract the ripcord for inspection. That means the ripcord could get extracted entirely during an emergency deployment. What's the plan for re-threading it? Mark Quote Share this post Link to post Share on other sites

What's the plan for re-threading it? Good question. Another thing that came to my mind is that probably a long Spectra line flapping in a freefall wind (after pulling the reserve to full arm length) is more likely to tie a knot with some part of deploying reserve. I thing it would be less likely with the "less flexible" metal cable... Especially if you throw your handle(s) after pulling (soft reserve pud or a loop with a spectra cable would fly "up" since it is so lightweight).

billbooth 10 #60 February 1, 2005 My new Spectra ripcord is "stiff" enough to thread easily through our stainless housing with no tools. It is only about 14" long, and with no pin on the end, I doubt it will ever tangle with a deploying canopy. Quote Share this post Link to post Share on other sites

"Soft" reserve handles generated forces nearly identical to metal handles. These numbers are from memory, but are probably pretty close. From other tests with the same scale, I have learned that if you pull "quickly", from a "running start" (slack in the cable), the pull force necessary to open the same reserve container is up to 300% lower than if you apply the force gradually to the handle. Most riggers only have a spring loaded fish scale, and therefore must apply pull forces gradually in order to read the scale. So, what reads 30 pounds on the fish scale in the loft, will only be around 10 pounds when you actually pull your reserve in an emergency, because I don't know of anyone who applies ripcord pull force "gradually" while falling rapidly toward the earth."
