In this article, a numerical investigation was performed on quadrotor UAV propeller with the aim of examining effects airspeed and rotational speed thrust coefficient, which is one most important parameters aerodynamic performance. that purpose, Computational Fluid Dynamics (CFD) analyses an 11-inch were carried out at different airspeeds speeds in vertical climbing flight condition. order to have optimum number mesh elements computational domain, independence also conducted. conclusion, results k-? SST turbulence model shown that, increase leaded higher turbulent kinetic energy. Furthermore, resulted differences between estimations experimental data, but found become more independent from airspeed.
