| 目的 适配发射过程无火药气体且弹丸不自旋的电磁发射技术，设计一种直接由空气作用的张开式尾翼。方法 该尾翼预制斜角，通过进气道气流在斜面上产生的压差，推动尾翼绕螺钉打开。采用动网格技术耦合流体控制方程、六自由度(6DOF)方程，对不同马赫数下尾翼张开过程进行仿真。结果 设计的空气作用张开式尾翼在流场作用下可以正常张开，来流流速为2、3、4马赫时，张开耗时分别为4.7、3.7、3.1 s。结论 该空气作用张开式尾翼方案设计有效。马赫数越高，张开过程耗时越短。迎风面积显著影响尾翼张开过程。 |

| The work aims to design a kind of open tail fin which is directly acted by air to adapt to the electromagnetic emission technology without gunpowder gas and projectile spin. The tail was prefabricated with a bevel angle. The pressure difference by inlet air flow on the bevel pushed the tail fin screw open. The process of tail opening under different Mach numbers was simulated by a coupling fluid control equation and a six degrees of freedom (6DOF) equation with dynamic mesh technology. The results showed that the air-acting open tail fin could open normally under the action of flow field. When the incoming flow rate was 2, 3 and 4 Ma, the opening time was 4.7, 3.7 and 3.1 s, respectively. The simulation results show that the scheme design is effective. Higher mach number means shorter opening time and the windward area significantly affects the opening process of tail fin. |
