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 CLanalysis on Neo-Ptero shows that the model has a promising CLperformance throughout the α increment. For every 2° angle of attack increment, the model can generate approximately 22% increment in CLmagnitude. Neo-Ptero also has a decent magnitude in maximum lift coefficient and stall angle at 1.24 and 18°, respectively. CLcomparison 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 CLmaxmagnitudes. However, Neo-Ptero suffers from severe CDgeneration by producing an average of 23.8% rise in CDmagnitude for every 2° angle of attack increment. A CDcomparison study in performance reveals that compared with other micro-UAV models, Neo-Ptero induces at least 13.2% and 5% larger CDmagnitude and CDincrement, respectively.
