Generate Quadcopter

The topology is optimised for the following scenarios impacting on an arm (which ended up looking more like a corner) of the frame: - flight (1.2N) - collision while climbing 5m/s (with a 250g payload that is a very ambitious climb rate) (24N) - frontal collision while flying at the full speed of 35mp/h (56.3km/h) (75N) - side collision while flying at the full speed of 35mp/h (56.3km/h) (75N) - diagonal collision while flying at the full speed of 35mp/h (56.3km/h) (75N) All of this is based on an educated guess (+counting frames of drone crash videos) of drone coming to a complete stop in 0.1s after colliding with an object. Hitting an object with a climb rate of 5m/s 480g = 0.48kg V = u + at 0 = 5 + a * 0.1 0.1a = -5 a = -5 / 0.1 a = -50 (m/s2) Force = mass * acceleration Force = 0.48 * -50 = -24N Hitting an object while flying at 56.3km/h 56.3km/h = 15.6m/s 480g = 0.48kg V = u + at 0 = 15.6 + a * 0.1 0.1a = -15.6 a = -15.6 / 0.1 a = -156 (m/s2) Force = 0.48 * -156 = -74.9N (approx. -75N) The mass of the frame ended up being 47 grams (instead of the intended 85g). All of the Generate credits were used up in one day :) The address of the optimised topology https://generate-de.frustum.com/#/workspace/594/scenario/1832 Thanks for the entertaining weekend Frustum! Mary Christmas and Happy New Year to everyone!
