New 9 cell non cross braced Schumann planform wing from PD? Surprised it hasn't been mentioned yet. Katana replacement? Crossfire competitor? Quote Share this post Link to post Share on other sites

danielcroft 2 #7 November 13, 2014 The NEOS has 3 cross braced (or z or whatever they're calling them) center cells. Have a look at the video, this wing has no cross bracing at all but does have inflatable stabilizers. Quote Share this post Link to post Share on other sites
piisfish 140 #8 November 13, 2014 That's what I'm saying. Ram air stabilisers. QuoteThe ICARUS NEOS is the finest high performance canopy in the market today. Its innovative aerodynamic and structural design characteristics, the new ARC1 Bracing (Advanced Rib Construction), the innovative SICS1 (Synchronized Inflow Control System) and the ERAS (Enhanced Ram Air Stabilizers) mark a new era in ram air canopy design technology. scissors beat paper, paper beat rock, rock beat wingsuit - KarlM Quote Share this post Link to post Share on other sites
hookitt 1 #9 November 14, 2014 That's going to be nice. I want to try one to see how well it performs as a non cross brace canopy.My grammar sometimes resembles that of magnetic refrigerator poetry... Ghetto Quote Share this post Link to post Share on other sites

Speed-Flyer 0 #17 November 16, 2014 QuoteNew 9 cell non cross braced Schumann planform wing from PD? I think people are awfully confused about what the schuemann (don't forget the 'e') planform is about... Hint: Forget about the nose, it is all about the tail and reducing wingtip vortices. Once you round the tail at all, you no longer have a Schuemann planform. Simple. The photo attached clearly show the tail (of Valkyrie) has been rounded much like the tail of this 9 cell no x brace thing. A true Schuemann planform will have a tail that is either completely straight or slightly swept back. For those that are interested here is an article about it written by the man himself. http://spieltek.com/sunbirdsoaring/soaringarticle/schuemannwingplanformarticle.pdf Do PD actually claim this is a Schuemann planform canopy? I am sure it is a great canopy but not a Schuemann planform at all... Quote Share this post Link to post Share on other sites

This is a better photo,http://performancedesigns.com/images/galleries/valkyrie/content/_MG_9515_large.html but still not perfectly straight, could be photo angle or input on the canopy or it's tapered at the end cells.

Speed-Flyer 0 #20 November 16, 2014 QuoteI think you guys are talking about two different canopies. Nope, there is simply not any photos of this new prototype that I could easily link. The video shows the same picture that we are describing though. Lets not make a big deal out of it though... I have just read quite a bit and this is something I know a little about so felt I had the experience to comment about it. The Schuemann thing has come up a bit on the threads from what I have seen with my limited reading here, I wonder where it comes from? Quote Share this post Link to post Share on other sites
danielcroft 2 #21 November 17, 2014 I read that paper a week or two ago. I guess what I took (maybe wrongly) from it was that the aerodynamic effect of the Schuemann concept was a sliding scale which is optimized by a completely straight trailing edge? Regardless, you can pull a screen grab from the PD release video if you want to see what the trailing edge of the new canopy looks like. To me, it looks similar to the VK.

Speed-Flyer 0 #22 November 17, 2014 QuoteThe Schuemann planform is basically a wing with a straight trailing edge and a leading edge who's sweep back increases progressively toward the tip... Sometimes the trailing edge at the tip also curves back to form a point where it meets the leading edge.. The intent is to push the tip vortices out increasing the effective wing span and reducing induced drag. And yes I agree it looks similar to the VK ( I assume that means Valkyrie?) which is not a Schuemann planform for the stated reasons as far as I can see. Are you saying these canopies are in fact a schuemann planform or? Quote Share this post Link to post Share on other sites
ianmdrennan 2 #23 November 18, 2014 I believe the claim is "based on" the plan-form. Not sure (could be wrong) that either of the players (PD, or NZ) have claimed to have copied the plan-form, but rather have based designs on it. And I laughed my ass off at the NZ video - well played lads! Performance Designs Factory Team Quote Share this post Link to post Share on other sites
skow 6 #24 November 19, 2014 so what do the inflatable stabilizers do? Quote Share this post Link to post Share on other sites
DocPop 1 #25 November 19, 2014 skowso what do the inflatable stabilizers do? I believe the idea is to reduce drag due to wingtip vortices (air "spilling" from the high pressure area under the wing to the low pressure area on top). This is the same theory as the winglets on jet wings. Why inflatable? I think just to get them to perform better. If you look at conventional stabilizers a lot of the time they are fluttering - this in itself is creating drag. Just my thoughts as in interested party, but not an aerodynamicist."The ground does not care who you are. It will always be tougher than the human behind the controls." ~ CanuckInUSA Quote Share this post Link to post Share on other sites
