This is a really good way to demonstrate the difference that VGs make to the airflow. Notice that outer portion of the wing, behind the VGs, doesnt stall at all, and the airflow remains attached and smooth. Notice that the inner portion of the wing, without VGs, stalls suddenly and the disruption immediately spreads over the whole portion. But note that the disruption doesnt spread to the portion of the wing behind the VGs. Vortex generators (VGs) are well-proven for better low-speed handling, softening the stall characteristics, and lowering the stall speed, which makes it easier to do slower, gentler landings. Stolspeed VGs are streamlined for less drag and better appearance than other VGs. Stolspeed VGs have no sharp points and are flexible, so it's easier to wash or cover the wings. The special 3M adhesive is removable without damaging aircraft paint. Advantages Stolspeed VGs Stolspeed VGs have been completely redesigned from all other vortex generators on the market to be much more user-friendly and better looking, while still retaining the aerodynamic effectiveness that vortex generators are renowned for. See Design. Stolspeed VGs have a very slim rounded fin to give them good flexibility, and a rounded, tapered base that flows into the wing surface. They really do look like theyre meant to be a part of the wing rather than a stick-on. In clear material theyre almost invisible. Brush your hand over Stolspeed VGs and you can feel the flexibility. .....like stiff resilient feathers..... Other vortex generators are sharp, angular and rigid, and are a real nuisance when refuelling, washing, or covering wings you wouldnt dare brush your hand over them! Dimensions: .5X3X8.5
