Leading-Edge Slats for Horten Wing Stiletto

thingiverse

These cutting-edge slats are engineered to decrease the landing speed and defer stall onset.\r\nOn the Horten wing "Stiletto" (designed by Raimund Sonst), the landing speed can be reduced from approximately 70 km/h to 35 km/h.\r\nThe example for this is the Me 163 B.\r\nUli, who has also modified a second Stiletto in the meantime, reports that the angle of attack in slow flight can be significantly increased without provoking one-sided or complete stalls.\r\nThis video shows his maiden flight\r\nhttps://www.youtube.com/watch?v=x1Wof6RPNuI\r\n<iframe width="640" height="360" src="https://www.youtube.com/embed/x1Wof6RPNuI" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>\r\n\r\nMore information about the aerodynamics and design of the slats can be found at http://www.rc-network.de/forum/showthread.php/698289-3D-gedruckte-Vorfl%C3%BCgel-f%C3%BCr-Horten-Stiletto\r\n\r\nThe short carbon tubes are intended to glue mounts 2 and 3 exactly in line with each other.\r\n\r\nPrint Settings\r\n\r\nAll wing parts were printed in spiral vase mode \r\nextrusion width = 0.6 \r\nlayer height = 0.2 \r\nno bottom/top solid layers.\r\n\r\nmounts 1 – 3 and spacers\r\nextrusion width = 0.3 \r\nlayer height = 0.2 \r\nperimeters = 3\r\nbottom solid layers = 2\r\ntop solid layers = 3\r\nfill density = 30%\r\n\r\nmount 4\r\nextrusion width = 0.3 \r\nlayer height = 0.2 \r\nperimeters = 2\r\nbottom solid layers = 2\r\ntop solid layers = 3\r\nfill density = 30%
