Analisis Gaya Aerodinamika terhadap Penambahan Tiptank pada Wingtip Pesawat N219 Nurtanio Menggunakan Software ANSYS

Abstract

This research analyzes the aerodynamic effects of adding an external fuel tank (EFT) on the N219 Nurtanio aircraft wingtip using Computational Fluid Dynamics (CFD) simulation in ANSYS Fluent. The study compares lift coefficient (CL) and drag coefficient (CD) for wings with and without EFT under four angles of attack (0°, 4°, 5°, 6°) at a cruise speed of 310 km/h. The N219 wing uses the NACA 63A-418 profile. Results show that the configuration with EFT provides a slightly lower CL (0.028) but improves aerodynamic efficiency with a higher CL/CD ratio (19.316 vs. 18.9768), indicating better cruise performance. The findings confirm that the addition of EFT on the N219 wingtip enhances aerodynamic efficiency, supporting extended flight range for potential maritime or long-range missions.
