Experimental Quadcopter Airframe · 模型 239261
A Quadcopter Airframe, principially designed for experimental use. In place of velco strips you can use o-rings or rubber bands, for an alternative fastening of the four speed controllers, electronics and the battery. The improvement of this design is still in progress and updates will come after time to time, just right before ending of submission. This design - not really attractive, but may be with functional significance - will be my one and only entry for this amazing challenge.

Many thanks to him for sharing! Engineering specifications, just as a reminder: Max. permissible mass of airframe: 90 g Mass of electronics: 42 g Mass of batterie: 47 g Total mass of motors and propellers: 26 g Mass of wires: 25 g Mass of payload: 250 g Total permissible mass (without airframe): 390 g Force of each motor: 1,17 N (120 g) Total force of the four motors: 4,68 N (480 g) Properties of my model: Selected material: Ultem 9085 Density of material: 1,34 g/cm^3 Volume of part: 14 cm^3 Mass of part: 18,8 g Mechanical values for FEM-Simulation: Material Strength Allowable: 4500 PSI Young's Modulus: 325 KSI Poissons Ratio: 0,41 Load in Z-direction: 0,45 kg-f Results of FEM-Analysis ( see also uploaded » Application-Snaps « ) : Max. displacement after deformation: 0,103 mm Max. "Stress von Mises" : 4354,3 psi The model is available in STEP (.stp)- and (.stl)-format.
