QUADCOPTER DESIGN ANALYSED

grabcad

This quadcopter design, an efficient tool for delivering essential items, boasts a precise arrangement of electronics, electronic speed controllers, motors, battery, and payload within its specified weight limit. The model's engineering specifications include a max airframe mass of 90g, 42g for electronics, 47g for the battery, 26g for motors and propellers, 25g for wires, and a 250g payload capacity. With a total permissible mass (excluding airframe) of 390g, each motor generates 1.17N force (equivalent to 120g), resulting in a combined force of 4.68N from the four motors. The selected material is Ultem 9085 with a density of 1.34g/cm³ and a part volume of 14cm³, weighing 18.8g. Mechanical values for FEM simulation include a material strength allowance of 4500 PSI, Young's Modulus of 325 KSI, and Poisson's Ratio of 0.41. The model is available in STEP (.stp) and STL (.stl) formats, supporting payloads up to 250g, making it a powerful quadcopter design.
