摘要
To increase the ratio of lift to drag of guided bomb, a folding multi-surface wing was designed. Computational fluid dynamics (CFD) numerical simulation method and semi-empiric method was used to compare the aerodynamic characteristics of folding multi-surface wing to that of diamond back wing with the same airfoil, chord and surface area. The results indicate the following facts: the lift coefficient of folding multi-surface wing is close to the diamond back wing at small angle of attack, but, at large angle of attack, the lift coefficient of folding multi-surface wing is larger than that of diamond back wing. The folding multi-surface wing has largest ratio of lift to drag. In addition, the rolling damping of folding wing is smaller than that of diamond back wing.
