“…There are two types of airfoils, namely symmetrical and asymmetrical airfoils, symmetrical airfoils are types where the top and bottom of the airfoil are the same shape, while asymmetric airfoils have different shapes at the top and bottom. [5]…”

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

An airfoil is a geometry shape of an aircraft wing designed to produce high lift force and low drag forces. Study on the air flow and pressure around of the airfoil was important step to analysis lift force and drag force. Factor affecting the lift force and drag force airfoil are the geometry and dimensions of the airfoil. This study to discus about the modification airfoil NACA 1408 was performed by adding round tip in leading edge to obtain simulate air flow by varying the angle of attack. The result showed that coefficient of lift (Cl) and coefficient of drag (Cd) was calculated from the simulations, data the highest Cl and Cd were 0.00277 and 0.00025 for the standard airfoil and for modification airfoil were 0.00343 and 0.00064. Based on the test result, the modified airfoil can produce better lift force than the standard shapes for test speed of 20 m/s. Airfoil merupakan bentuk geometri sayap pesawat terbang yang dirancang untuk menghasilkan lift force tinggi dan drag force rendah. Studi tentang aliran udara dan tekanan di sekitar airfoil adalah langkah penting untuk menganalisis lift force dan drag force. Faktor yang mempengaruhi lift force dan drag force airfoil adalah geometri dan dimensi airfoil tersebut. Penelitian ini membahas tentang modifikasi dilakukan pada airfoil NACA 1408 dengan menambahkan ujung bulat pada leading edge dan mendapatkan simulasi aliran udara dengan memvariasikan angle of attack. Hasil penelitian menunjukkan bahwa coefficient of lift dan coefficient of drag dihitung dari simulasi, data coefficient of lift dan coefficient of drag tertinggi adalah 0.00277 dan 0.00025 untuk airfoil standar dan untuk airfoil modifikasi adalah 0.00343 dan 0.00064. Berdasarkan hasil pengujian, airfoil modifikasi dapat menghasilkan lift force lebih baik daripada bentuk standar untuk kecepatan uji 20 m/s.
