| Abstract: | The current development of small unmanned aerial vehicles(SUAV) by the platform of fixed-wing is discussed.The aerodynamic characteristics of low Reynolds number,and the influence to laminar separation bubble and lift-drag ratio are analyzed.According to the design performance aim,we estimate the overall parameters and complete the shape design of two schemes.Normal and tailless layouts are respectively applied.Then we use different airfoil and wing with low Reynolds number and the aerodynamic analysis of t... |
