Fluidity Foilsurfing wing.

prusaprinters

<p>Design wingspan is approx 980mm, longest section front to back is approx 220mm and chord at fuselage position is approx 30mm ,<br/> Profile scales smaller toward wingtip while keeping generally same shape apart from some modification by the wingtip downward sweep.<br/> The wings are swept back slightly to promote loosing any seaweed that may be collected.</p> <p>I've researched and targeted this at the heavier rider to be an entry level foil with potential to last for some time, as I have kitesurf and windsurf experience, however it's intended for wingfoiling although it's probably fine for lighter SUP foilers as well. For wing foiling it's recommended to sand round the ends smooth to reduce injury risk and ILE wing fabric piercing risk.</p> <p>This profile and surface is independently mathematically created with a variant of my cylinder drawing program.</p> <p>Joining: Clear out the end joiner holes on the 1:1 size wing with a 3.5mm drill bit and join with bamboo skewers.<br/> Clean out the tail wing(print half sized) with 1.75mm drillbit for the joiners and find wire, big diode ends etc cut to 18mm long rods for the joiners, use superglue.</p> <p>Reinforcing: most of the strength required is tensile underneath and compression on top. Recommended kevlar underneath then 2 layers of basalt.<br/> On top: wide strip of 400gsm basalt or carbon fibre unidirectional over kevlar with patches of different sizes around the screw holes and then 2 layers of basalt cloth.</p> <p>Resing infusion recommended if you have the equipment.</p> <p>Screw holes are M8 for the 1:1 size and M4 for the small size. Spacing is 120mm between centers for the 1:1 size and 60mm for the half size.<br/> Shop around for the SS bolts, they are loaded with a lot of force if you crash into something at speed.</p> <p>Wing clamps are included to set the angles on a flat fuselage. The tail wing can be set for angles of negative atack from 0° to 2°​ in 0.5°​ steps.<br/> Tail wing is designed to mount ABOVE the Fuselage</p> <h3>Print instructions</h3><p>Uses almost 2kg of filament. PLA+ recommended. Your printer needs to be able to clear 250mm height. Use prusaslicer to split the parts into seperate models if you have problems or need to reprint an individual component. If you have interlayer adhesion problems then set your nozzle width in advanced to 1.1 times actual for each motion type except for bridging. I'm printing in the middle of winter so if you use my gcode files for my cube printer and the setting is too hot then adjust after the first layer.<br/> Cubic infil at 30%, layer height of 0.2mm, 3 perimeters and 6 layers top and bottom. Cubes won't form correctly(sealed) if layer height is too much.</p>
