The invention provides an underwater vehicle fin rudder optimization device based on steady active flow control, and relates to the technical field of underwater vehicles, the underwater vehicle fin rudder optimization device comprises an active flow control system and a plurality of injection and suction execution mechanisms, and the surface of a fin rudder is provided with a plurality of injection and suction ports. The spraying and sucking executing mechanism is arranged at the spraying and sucking opening and can spray fluid to the outside of the fin rudder through the spraying and sucking opening and suck external fluid into the fin rudder through the spraying and sucking opening, and the active flow control system controls the spraying and sucking executing mechanism to spray the fluid outwards or suck the fluid inwards. The jet-suction executing mechanisms are arranged at different parts of the fin rudder, and flow control targets of different parts of the fin rudder of the underwater vehicle under different flow control strategies are achieved in combination with the active flow control system. Finally, the optimization design of the fin rudder of the large underwater vehicle is realized, and the engineering practical problems of improving the rudder effect of the rudder sheet, delaying the failure of the rudder sheet, reducing the adverse effect of the large rudder angle of the rudder sheet and the like are solved through active flow control fit.

本发明提供一种基于定常主动流动控制的水下航行器鳍舵优化装置，涉及水下航行器技术领域，包括主动流动控制系统和多个喷吸执行机构，鳍舵表面设置有多个喷吸口，喷吸执行机构设置于喷吸口处并能够通过喷吸口向鳍舵外喷射流体，也能够通过喷吸口将外界的流体向鳍舵内吸流，主动流动控制系统控制喷吸执行机构向外喷流或向内吸流。本发明通过在鳍舵不同部位布置喷吸执行机构，结合主动流动控制系统实现不同流动控制策略下的水下航行器鳍舵不同部位的流动控制目标；最终实现水下大型航行器鳍舵的优化设计，通过主动流动控制契合解决提高舵片舵效、延迟舵片失效、降低舵片大舵角不利影响等工程实际问题。
