摘要
Abstract
The box‐wing layout with canard could significantly improve the whole vehicle’s longitudinal pitching moment properties .For the box‐wing layout of UAV ,the canard’s influence on the aerodynamic performance of box‐wing layout ,and the influence of the canard installation angle ,canard longitudinal position along the body axis ,and canard area on the aerodynamic performance of box‐wing layout under cruising flight are studied through numerical simulation .Results show that :canard can increase the box‐wing layout’s maximum lift coef‐ficient and the stall angle of attack ,and can effectively regulate the longitudinal pitching moment ,but will slightly reduce the maximum lift‐to‐drag ratio ;under cruising angle of attack of 3° and cruising speed of 50 m/s ,the installation angle and area of canard will have a great influence on the aerodynamic performance of box‐wing layout while the canard longitudinal position will affect less on the box‐wing layout .Above all ,it can be concluded that the canard can significantly improve aerodynamic performance of the box‐wing layout with the comprehensive consideration of these parameters of canard .关键词
