边条式前翼的制导航弹气动特性

Pneumatic Characteristic of Guided Bomb for Trim Rectangular Front Wing

针对四片边条式矩形前翼与弹翼、尾舵形成的"×-×-×"和"+-×-×"配置的2种气动布局的制导航弹,应用数值方法对绕流流场进行了模拟,并依据数值计算结果从升阻特性和纵向静稳定性两方进行初步探讨,得出了"×-×-×"和"+-×-×"2种气动布局下制导航弹的气动差异。

Aimed at the configuration of four trim rectangular front wing,wing and rudder,the paper formed ＂×-×-×＂ and ＂＋-×-×＂ aerodynamic layout of the two guided bombs.By means of numerical computing method,it simulated the wound flow field,and tentatively explored the lift-drag characteristics and longitudinal static stability.Finally it obtains the aerodynamic differences of guided bombs under the two air distribution system of both ＂＋-×-×＂ and ＂×-×-×＂ aerodynamic layout.
