摘　　要：为进一步提升水下航行体操纵性能,在传统水下航行体操纵面上引入吹吸射流装置。采用正交设计方法对射流的流量、吸流口位置和吹流口位置进行优化设计,获得最佳参数组合。用RANS求解器评估安装了吹吸射流装置的水下航行体的水动力性能,并将其与传统水下航行体相比,验证了该装置在提升操纵性能方面的作用。在典型工况下通过舵剖面涡流场结构、流线和压力分布云图对吹吸射流的水动力机理进行了深入分析,研究成果可为吹吸射流装置在水下航行体的工程应用提供理论依据。To improve the maneuverability of underwater vehicles the blow suction combined jet(BSCJ)device is adopted into the design of traditional controlling surfaces.The orthogonal design method was adopted to optimize the jet flow rate,and the suction/blow point and optimal combination parameters were obtained.The RANS solver was utilized to evaluate the hydrodynamic performance of an underwater vehicle with the BSCJ device.The effect of the BSCJ device on improving maneuverability was verified by comparing it with the traditional underwater vehicle.The internal flow mechanism was analyzed from vortex structures and pressure/velocity contour maps.The research results can provide theoretical guidance for applying the BSCJ method to underwater vehicles.
