摘　　要：零航速减摇鳍具有双重工作模式,不同生力机理使其流体动力特性存在本质差异,从而导致二者对鳍型参数要求截然不同,为满足零航速模式需求,零航速减摇鳍大多选用小展弦比鳍型,但亦给常规减摇模式带来诸多不利影响。通过分析展弦比、翼梢形状等因素,从双模式对鳍型参数的实际要求出发,应用线性系统理论、对抗控制原理,提出适用于零航速减摇鳍的尺寸参数估算及综合评定方法,得出不可收放式零航速减摇鳍的最佳展弦比范围,为工程化设计提供了必要的理论依据。The different force generation mechanisms employed by zero-speed fin stabilizers under two working modes result in the essential differences existing in their hydrodynamics, and it .induces the absolutely opposite requirements of fin sizes for each other. To damp the rolling motion effectively under the zero-speed mode, fins with the low aspect ratio are always used and however this also has several adverse influences on the conventional mode. With analysis of reasons such as the aspect ratio and wing tip, a method on fin size estimation and integrated evaluation for zero-speed fin stabilizers is proposed using the linear systems theory and opposed-control principle according to the detail requirements for the two modes. The optimal range of aspect ratio for non-retractable fins is obtained and the necessary theoretical basis for engineering design is provided.
