Firstly, a model of wing with the NACA4415 across area is considered under the effect of low speed air flow at different coming angles. The aerodynamic characteristics of this airfoil will be simulated, calculated and analyzed. Based on the analysis, the author proposes a new design of UAV airfoil in order to improve the aerodynamic performance of the wing. Several profiles of proposed design have been investigated in the similar airstream conditions with respect to the initial one by using the numerical simulation method on COMSOL software. The results show the good response of the new design. This research can apply for the design and construction tasks about unmanned aerial vehicle (UAV) in Vietnam. date: 2016-08 date_type: published publisher: Hanoi University of Industry full_text_status: public publication: Journal of Science and Technology volume: 35 pagerange: 35-38 refereed: FALSE issn: 1859-3585 citation: Nguyen, Ngoc Viet and Hoang, Van Manh and Nguyen, Ngoc Linh (2016) Research on improving aerodynamic performance of an UAV airfoil using numerical simulation method.
