Why you should avoid too large winglets – from our Aerodynamic Chief Engineer Johan Bosman
The image shows a flow field around a wing tip without a #winglet. More precisely, it shows the extent of positive inflow angles at the tip region. The addition of a winglet would utilize this flow field and increase performance, only if it is inside the boundary of positive inflow angles. At higher flight speeds, the […]
JS5 (Open Class Single seater) wing design from our Aerodynamic Chief Engineer Johan Bosman.
The #JS5 wing has 2 sections per side with a removable winglet (as strongly recommended by Cobra trailer design team). The 4 flaps per side are driven by 4 drivers, as the aerodynamic twist associated with these long wings could just not be structurally designed out. Intensive wing and flap twist modulations were performed to ensure we […]
JS3 high wing design – from our Aerodynamic Chief Engineer Johan Bosman
Why did you select a high-wing configuration on the JS3? Top performance sailplanes essentially must have the ability to climb and cruise better than its competitors. This implies that winning gliders have to be efficient flying machines at both low and high flight speeds which are, in many cases, contradictory design specifications. All parts, which […]
