Armstrong DWP Downwind Foil Wing

DWP   Development of the Downwind Performance foil began by collecting waveform and real world riding data from Hawaii's interisland channels to set specific performance parameters for the design process. A team of leading fluid dynamics experts optimized a foil shape with extreme top end glide at high speeds, but with enough low end lift to still make average conditions accessible. The result is a very high aspect ratio outline with swept wingtips and relatively minimal rondure. The DWP foil section is high camber from root to wingtip, yet thin overall to achieve that combination of top speed efficiency without losing low end accessibility.     DWP 685  Area: 685cm2 Span: 960mm Aspect Ratio: 13.55   DWP 755 Area: 755cm2 Span: 1000mm Aspect Ratio: 13   DWP 930 Area: 930cm2 Span: 1100mm Aspect Ratio: 13
