Generate Quadcopter Frame 40

grabcad

In my second attempt at The Generate Quadcopter Challenge (https://grabcad.com/challenges/the-generate-quadcopter-challenge), I made certain assumptions for frame optimization. These included forces such as electronics (42g, 0.412N), motor thrust (120g, 1.177N per motor), wires (25g, 0.245N), battery (47g, 0.461N), and payload (250g, 2.4525N). I distributed the wire weight between electronics and motors as 0.08175N each. The forces used in the simulation were electronics (with four speed controllers) at 0.57552N, motors (four units) at 0.33681N, motor thrust per motor at 1.177N, battery at 0.46107N, and payload at 2.4525N. To account for no payload and minimum thrust, I set the stand's force at 0.01N. For flight scenarios, I considered two load cases: Fly1 with surface payload mounting (including component weight and full thrust) and Fly2 with area thrust (only component weight). I attached electronics, battery, and payload using adhesive-backed Velcro or zip ties. Special thanks to Frustum for the software experience.
