Manufacture of UAV Skywalker 1900 Flying Vehicles Made of Composites

Abstract

The purpose of this research is to make a flying vehicle with the SKYWALKER 1900 UAV model for mapping missions with fiber glass reinforced composite materials on the wings and carbon fiber on the fuselage and tail. With composite materials, it is hoped that the structure of the UAV SKYWALKER 1900 will be stronger than previous materials using styrofoam. The method for making flying vehicles in this study uses 3D printing, to print UAV parts such as wings, fuselag and tail. then molding for components is made, and the final stage is manufacturing parts with composites using glass fiber and carbon fiber reinforcement using the vacuum bagging method. the analysis of weight deviation on the fuselag has a value of 70% and the weight deviation on the wings is 52%, the size deviation on the fuselag and wings weight occurs due to the putty process during finishing. the results of the aerodynamic analysis on the fuselag using solid work software, the UAV flight limit is 20 m/s to get the best flight results when flying

Testing the Bending Strength of Carbon Fiber Composites using the vacuum infusion and vacuum bagging method on the UAV Skywalker 1900 Fuselage Material

“…Then, resin is injected after the space inside the plastic bag is put under low pressure, and the process continues until the entire fiber is impregnated with resin. On the other hand, in the vacuum bagging process, dry fibers are placed between the fix mold, and resin is manually applied evenly using a brush onto the fiber surface [10]. The specimen manufacturing process utilizes the vacuum infusion method.…”

“…Drone technology has been instrumental in territory mapping in Indonesia, an archipelagic nation [7]. A vehicle's wing development is a multi-stage process that includes wing profile selection, geometric calculations, structural design, material maintenance, numerical analysis, and manufacturing [10], [11]. One of the most challenging difficulties in aviation is determining how to progress.…”

“…This technique involves vacuum infusion and vacuum bagging to create composites, which is relatively straightforward. Manufacturing composite materials using vacuum infusion involves pressing matrix, fiber, and other layers into the mold while utilizing an airtight bag, merging the layers into a composite material [10], [17], [20]- [29].…”
