为寻求一种具有良好稳定性和气动效率的翼型，进而提高潜艇指挥台围壳和尾翼的稳定性和气动性能，受到座头鲸和猫头鹰独特翼型结构的启发，首先设计两类锯齿状仿生翼型，通过数值求解非定常Navier-Stokes方程，揭示相同雷诺数条件和相同攻角下不同锯齿尺寸的仿生锯齿翼型的气动特性与流场特性，并与NACA0012翼型性能进行比较。研究结果表明，升阻比有所提高，流场品质有所提升，有利于气动效率的提高，为潜艇性能提升打下良好基础。
In order to seek an airfoil with good stability and aerodynamic efficiency, and to improve the stability and aerodynamic performance of the submarine command podium shell and stern wing, inspired by the unique airfoil structure of humpback whales and owls, two types were first designed, the zigzag bionic airfoil, by numerically solving the unsteady Navier-Stokes equation, reveals the aerodynamic characteristics and flow field characteristics of the bionic zigzag airfoil with different serrated sizes under the same Reynolds number condition and the same angle of attack, and compared with NACA0012 airfoil performance for comparison. The research results show that the lift-to-drag ratio and the quality of the flow field have been improved, which is conducive to the improvement of aerodynamic efficiency and lays a good foundation for the improvement of submarine performance.
