Manufaktur Pesawat Tanpa Awak Jenis Flying Wing dengan Metode Fused Deposition Modelling Menggunakan 3D Printer

Abstract

Unmanned Aerial Vehicle is a flying vehicles that are controlled by the pilot using remote control and can be controlled by the pilot through a program that has been designed. The UAV manufacturing process is a very important factor to produce an excellent product. In this final project, a unmanned aerial vehicle type flying wing is manufactured using the FDM (Fused Deposition Modeling) method using a 3D printer. Starting with design adjustments to get the lifting force parameter above 12.72 N. These parameters are determined to achieve the weight of the component which is estimated to have a mass of 2360 grams. With this value, a design adjustment by increasing the scale to 1:1.3 was carried out to increase the wing area and span length. Followed by manufacturing planning using the Creality Ender 3 Pro 3D Printer. Design adjustments as objects to be printed through FDM 3D print fabrication were prepared using the Solidworks 2018 software and Ultimaker Cura so that the printed object could enter the printer work area of 220 x 220 x 250mm. The resulting parts of the 3D printed object are assembled through an assembly process using special glue as an adhesive and carbon tube as a spar or structural reinforcement of the vehicle.

The result of this final project is that the weight of the vehicle is 2060gram where the weight is lighter than the weight calculation performed using the Ultimaker Cura software of 2321gram. This vehicle also has a structural strength with a maximum stress of 41,42MPa, a maximum displacement of 5,3mm, and a maximum strain of 4,033Pa. The data was obtained through simulation using Solidworks software using the tensile test results as a parameter of the characteristics of the PLA material with an infill density of 2% and a gyroid pattern.
