Abstract

Perkembangan Unmanned Aerial Vehicle (UAV) untuk kebutuhan pemantauan, misi taktis, dan operasi pada area terbatas mendorong pengembangan desain yang lebih portabel dan efisien, salah satunya melalui konfigurasi folded wing yang memungkinkan sayap dilipat untuk meningkatkan kemudahan transportasi dan peluncuran. Namun, mekanisme lipatan memerlukan desain struktur yang ringan, kuat, serta tetap mampu mempertahankan performa aerodinamika dan kestabilan terbang. Penelitian ini bertujuan merancang dan membangun airframe folded wing UAV menggunakan metode 3D printing berbasis Fused Deposition Modeling (FDM) dengan material termoplastik PLA+, serta mengevaluasi karakteristik aerodinamika dan strukturalnya. Metode penelitian meliputi pemodelan Computer Aided Design (CAD), analisis aerodinamika menggunakan Computational Fluid Dynamics (CFD), analisis statis struktural berbasis Finite Element Method (FEM), proses manufaktur menggunakan 3D printing material PLA+, integrasi sistem avionik, serta pengujian performa. Hasil penelitian menunjukkan bahwa desain folded wing UAV mampu menghasilkan karakteristik aerodinamika yang mendukung pembentukan gaya angkat dan kestabilan terbang, dengan distribusi tekanan dan pola aliran udara yang masih berada pada batas operasional desain, sementara hasil analisis struktural menunjukkan bahwa tegangan dan deformasi yang terjadi masih berada dalam batas aman material PLA+. Implementasi metode 3D printing juga terbukti mampu menghasilkan geometri kompleks secara presisi serta mempercepat iterasi desain dan proses manufaktur. Dengan demikian, rancangan airframe folded wing UAV berbasis 3D printing menggunakan material termoplastik PLA+ dinilai layak untuk mendukung kebutuhan UAV portabel yang ringan, mudah diproduksi, dan memiliki performa struktural serta aerodinamika yang memadai.

The increasing utilization of Unmanned Aerial Vehicles (UAVs) for surveillance, tactical missions, and operations in confined areas has encouraged the development of more portable and efficient designs, one of which is the folded wing configuration that enables the wings to be folded to improve transportation and deployment efficiency. However, the wing folding mechanism requires a lightweight and robust structural design while maintaining aerodynamic performance and flight stability. This study aims to design and develop a folded wing UAV airframe using the 3D printing method based on Fused Deposition Modeling (FDM) with PLA+ thermoplastic material, as well as to evaluate its aerodynamic and structural characteristics. The research methodology includes Computer-Aided Design (CAD) modeling, aerodynamic analysis using Computational Fluid Dynamics (CFD), static structural analysis based on the Finite Element Method (FEM), manufacturing through 3D printing using PLA+ material, avionics system integration, and performance testing. The results indicate that the folded wing UAV design is capable of generating aerodynamic characteristics that support lift generation and flight stability, with pressure distribution and airflow patterns remaining within the intended operational range. Furthermore, the structural analysis demonstrates that the resulting stress and deformation remain within the safe limits of PLA+ material. The implementation of 3D printing technology also proves effective in producing complex geometries with high precision while accelerating design iterations and manufacturing processes. Therefore, the proposed folded wing UAV airframe manufactured using 3D printing and PLA+ thermoplastic material is considered feasible to support the development of lightweight, portable UAVs with adequate structural and aerodynamic performance.
