Visual design optimisation – Triple Seven VDO technology
There’s more to the design than meets the eye. Each and every seam has been placed precisely where it is for a reason, and there are no more seams in the canopy than necessary for the optimal panel tensioning everywhere. The reason we mention this is if you design for looks rather than for efficiency you often end up with many more seams than you should ideally have, and every single one will increase the total air permeability of the canopy. In extreme cases this may lead to porosity issues at readings that wouldn’t normally be considered critical – if too much air is escaping via the many seams, then smaller increases in porosity in the individual panels may cause the whole wing to fall over the edge of what is still flyable.
When flying a Triple Seven wing you can rest assured that none of the design elements have been incorporated out of vanity – there are only technical solutions. Fortunately, the discerning pilot will instinctively associate efficient with attractive!
