摘要
液体晃动会对飞行器动力学和控制系统造成影响,为了降低液体晃动带来的负面影响,本文从被动控制角度出发,对常见的Cassini贮箱提出几种防晃设计方案,并探索不同因素对贮箱防晃性能的影响.通过Flow3d商业流体软件对比分析环形挡板贮箱、扇叶挡板贮箱、环形浮板贮箱的性能后,给出了一种挡浮板复合结构贮箱,并通过对比验证了这种思路的可行性.
Liquid sloshing will affect dynamics and control of aircraft.In order to reduce the negative impact of liquid sloshing,this paper proposes several sloshing suppression design schemes for common Cassini tanks from the perspective of passive control,and explores influences of different factors on the sloshing suppression performance.After comparing and analyzing the performance of annular baffle tank,fan baffle tank and annular floating plate tank by FLOW3D,a compound structure tank with baffle plate is proposed,and the feasibility is verified by a comparative study.
