The invention discloses a self-unfolding folding rudder without changing self fluid appearance and an assembling method, and belongs to the technical field of underwater unmanned equipments.The self-unfolding folding rudder is characterized in that a rudder shaft, a torsional spring mounting box and a torsional spring are all located in a rudder plate, the fluid appearance of the rudder plate is not changed, and a fixed rudder plate and a movable rudder plate are meshed through sawteeth, so that the rudder plate is fixed; when the self-unfolding folding rudder is in an unfolding state, almost no gap exists between the fixed rudder plate and the movable rudder plate, the movable rudder plate does not interfere with each other in the rotating process, the whole folding rudder does not generate gaps, protrusions or recesses due to a folding structure, the loss of hydrodynamic force is reduced, and the dynamic performance of an underwater navigation body is improved.

    本发明公开了一种不改变自身流体外形的自展开折叠舵及装配方法,属于水下无人装备技术领域,该自展开折叠舵的舵轴、扭簧安装盒、扭簧均位于舵板内部,不改变舵板流体外形,而且,固定舵板和活动舵板通过锯齿啮合,可以使该自展开折叠舵在展开状态下,固定舵板和活动舵板之间几乎没有间隙,并使活动舵板在转动过程中不发生干涉,整个折叠舵不会因为折叠结构产生间隙、凸起或凹陷等,减小了流体动力的损失,提高水下航行体的动力学性能。
