The invention discloses a method and a device for analyzing aerodynamic characteristics of a remote tail control guide shell. The method comprises the following steps: carrying out physical modeling on a shell body of a shell to obtain a shell model; performing unstructured grid division on the shell model and setting boundary conditions; and based on the divided grids and the set boundary conditions, carrying out aerodynamic characteristic analysis on the shell model to obtain a change rule of the aerodynamic characteristics of the shell model along with the flight Mach number and the attack angle. The technical problem that the control difficulty is large due to the fact that the rotating speed of the high-spinning cannonball is high is solved. 本发明公开了一种远程尾控制导炮弹气动特性的分析方法及装置。其中，该方法包括：对炮弹的弹体进行物理建模，得到炮弹模型；对所述炮弹模型进行非结构化网格划分并设置边界条件；基于所划分的网格和所设置的边界条件，对所述炮弹模型进行气动特性分析，得到所述炮弹模型的气动特性随飞行马赫数和攻角的变化规律。本发明解决了由于高旋制炮弹转速高而导致的控制难度大的技术问题。
