Hydrodynamic Performance Analysis of NACA0015 Flap Rudder at the Tail of Underwater Vehicle

水动力参数是水下航行器操纵性设计的重要参数。针对一款水下航行器使用的襟翼舵展开水动力性能分析。首先利用流体力学(CFD)对襟翼舵在不同工况下的水动力性能进行有限元分析,得到了襟翼舵的升力和阻力特性参数。然后通过对这些参数的比较分析,得到襟翼舵在不同工况下的最佳效率角度及最大升力角度。这些性能参数可为后续的水下航行器襟翼舵最佳控制策略提供重要的参考依据。

Hydrodynamic parameters are important parameters for the maneuverability design of the underwater vehicles.The finite element analysis is conducted on the hydrodynamic performance of a flap rudder used in an underwater vehicle under different operating conditions by using the computational fluid dynamics(CFD),and the lift and drag characteristics parameters of the flap rudder are obtained.By comparing and analyzing these parameters,the optimal efficiency angle and maximum lift angle of the flap rudder under different operating conditions are obtained.It provides important reference basis for the optimal control strategy of the flap rudder for subsequent underwater vehicles.
