garynothin 0 #1 Posted August 2, 2019 My Fusion by Precision Aerodynamics has no cascades in its lines. Every line is full length. Do manufacturers provide full length lines or with cascades as an option? Most of the canopies I see have cascades so I think I'm in the minority.

councilman24 36 #2 August 3, 2019 Canopies are generally designed and sold either with or without cascades. As far back as some of the earliest ram air canopies. The only option was non cascaded center A/B lines so non CRW specific canopies could be used more easily for CRW. In the 80's I added 900lb red dacron non-cascaded center lines to many canopies. 1 Quote Share this post Link to post Share on other sites
RiggerLee 61 #3 August 3, 2019 That's also a high load area during opening. When the slider spreads that center cell is the only one open. All the other cells are basically squeezed together to the width of the grommet. So if your whole line set is made of as light a line as possible, bulk/drag, then you may need continuous lines on the center A, B lines. When they started offering light weight HMA lines as an option on some canopies those line sets were non cascaded. I've also seen line sets with special line trims built non cascaded, a competitor was sent a line set to tweek the trim and it was non cascaded. In some ways noncascaded sets are better. It's just a trade off between bulk/drag and the stability of the trim of the airfoil. Cascades... wiggle back and forth depending on the load distribution cord wise on the airfoil.
