Abstract

This research is based on obtaining the best possible aerodynamic performance for the Quickster Narasena Bengawan UV Team UAV aircraft wing design. One of the factors that greatly affects the flying performance of a UAV is the wing. The wing on the Quickster Narasena UAV aircraft uses an MH33 airfoil, because MH33 is specifically for high-speed UAV aircraft. This research will discuss the comparison of the performance of a wing without a vortex generator with a wing with a vortex generator. Variations in the positioning of the vortex generator on the wing of the Quickster Narasena UAV will also be discussed in this study. The method used in this research is the CFD (Computational Fluid Dynamics) method. The simulation process will use the ANSYS Fluent 19.0 application with the K-Omega SST method with the Reynolds-Averaged-Navier-Stokes (RANS) equation as the basis. The purpose of this study is to obtain the results of the coefficient of drag, lift, and the contour of the turbulence that will occur. The simulation results that have been done are the geometry of the wing with the addition of a vortex generator can reduce the drag coefficient and can increase the lift coefficient.

Highlights

Unmanned Aerial Vehicle (Unmanned Aerial Vehicle) is a flying vehicle that is controlled remotely by the pilot or is able to move automatically according to the parameters that have been entered in the control system [1]
Every year the Bengawan UV Team participates in the KRTI competition, besides that the Bengawan UV Team has been involved in the business of photo mapping and monitoring services in an area
In making the Quickster Narasena Bengawan UV Team UNS aircraft, an initial design was needed as a start and in order to support the success of winning the race

Summary

Introduction

Unmanned Aerial Vehicle (Unmanned Aerial Vehicle) is a flying vehicle that is controlled remotely by the pilot or is able to move automatically according to the parameters that have been entered in the control system [1]. The use of UAVs has been widely used in several fields to facilitate human work. In the field of education, UAV itself has begun to enter and develop among universities in the world, and it has even become a competition between universities [2]. Bengawan UV Team is an unmanned vehicle research team focused on UAVs and USVs at Sebelas Maret University which aims to research, design and build unmanned vehicles for any mission required. It is necessary to consider the initial design phase related to the emphasis on the aerodynamics of the drone that will be made [4].
