Supra setup Mark Drela 15 Aug 05 =========== Decalage -------- With -2 camber setting (full reflex), the nearly-flat rear bottom of wing and the stab are parallel. CG position ----------- 3.6" (91.5mm) behind center LE Tow ring position ----------------- 3.8" (96.5mm) behind center LE (on a line perpendicular to wing bottom) Note: This is a fairly far aft hook position, which will probably require adding a touch of down elevator for the throw to prevent a stall at the top of the initial rotation. Once the glider settles down in the climb, the down-trim can be removed. I add the launch down-trim via an easy to reach slider (slider E on my Royal Evo). A switch would also work. Supra control throws ==================== All control throws measured at TE of the moving surface at the largest-chord location. Positive throw is TE down. Negative throw is TE up. Flight mode summary ------------------- 1) Normal 2) Launch mode - Enables 100% aileron differential - Enables additional aileron->rudder mixing Aileron throws ( 55mm between hingeline and TE, 1mm = 1.05 degrees ) -------------- +14mm aileron stick -14mm aileron stick + 0mm aileron stick | Launch mode (100% differential) -14mm aileron stick | 0mm -2 camber +2mm 0 camber +5mm +3 camber +9mm launch camber 0mm zero crow stick +3mm half crow stick (max CL for crawling) -10mm full crow stick (max CD for braking ) -2mm down-elevator stick +3mm up-elevator stick Flap throws ( 62mm between hingeline and TE, 1mm = 0.92 degrees ) ----------- +12mm aileron stick -12mm aileron stick + 0mm aileron stick | Launch mode (100% differential) -12mm aileron stick | 0mm -2 camber (baseline) +2mm 0 camber +5mm +3 camber +11mm launch camber 0mm zero crow stick +22mm half crow stick (max CL for crawling) +54mm full crow stick (max CD for braking ) NOTE: The larger the max flap crow deflection, the better. The +54mm deflection should be increased as much as possible. -2mm down-elevator stick +3mm up-elevator stick Elevator throws ( 82mm between hingeline and TE, 1mm = 0.70 degrees ) --------------- +11mm down-elevator stick -14mm up-elevator stick 0mm compensation with -2 wing camber (baseline) +1mm compensation with +3 wing camber +4mm compensation with half crow +9mm compensation with full crow +1mm compensation with launch camber Rudder throws ( 117mm between hingeline and TE, 1mm = 0.49 degrees ) ------------- +/-62mm rudder stick +/-15mm aileron stick +/-30mm aileron stick | when crow is more than half deployed +/-38mm aileron stick | Launch mode
