Computational Aerodynamics Study on Neo-Ptero Micro Unmanned Aerial Vehicle

Abstract

This work aims to characterize the lift (CL) and drag (CD) coefficient distributions on the current Neo-Ptero micro-UAV prototype. A CL analysis on Neo-Ptero shows that the model has a promising CL performance throughout the α increment. For every 2° angle of attack increment, the model can generate approximately 22% increment in CL magnitude. Neo-Ptero also has a decent magnitude in maximum lift coefficient and stall angle at 1.24 and 18°, respectively. CL comparison works reveal that Neo-Ptero performs better than the other micro-UAV model produce by Ming from National University of Singapore (NUS) and also Serindit (produced by UAV team from University Riau, Indonesia) particularly in terms of α range and CLmax magnitudes. However, Neo-Ptero suffers from severe CD generation by producing an average of 23.8% rise in CD magnitude for every 2° angle of attack increment. A CD comparison study in performance reveals that compared with other micro-UAV models, Neo-Ptero induces at least 13.2% and 5% larger CD magnitude and CD increment, respectively

Exploratory Study of Drone Data Stabilization with Implications in Vibration-based Structural Health Monitoring

“…Prior studies have explored drone parameters [33][34][35][36][37][38] such as their integrity, identification, and performance. Similar to a commercial airplane, the drone also maneuvers in three directions as shown in Figure 2.…”
