الملخص:A parametric study of low altitude small Unmanned Autonomous Vehicle (UAV) conceptual design was performed. The purpose was to estimate constraint diagram propulsive efficiency of propeller-Brushless Direct Current (BLDC) motor propulsion system at two different flight conditions with the consideration of Atmospheric Boundary Layer (ABL) turbulent effect. The lift slope and drag polar of the small UAV was obtained by simulating the airframe in FluentTM 6.3 using SST k-ω turbulence model at stall, cruise and maximum speeds.
