The invention discloses a combined elastic element for a folding rudder. The combined elastic element comprises a main torque piece, a first connector, a second connector and a torsional spring, wherein the first connector and the second connector are arranged at the two ends of the main torque piece; the main torque piece is a torsion piece set or a torsion bar. The combined type elastic element is simple in structure and low in cost, the combined type elastic element is embedded in the folding rudder surface, the aerodynamic shape is not affected, the folding rudder can be achieved without changing the shape structure of the folding rudder, the initial torque is greatly improved, and the initial kinetic energy is increased.

    本发明公开了一种用于折叠舵的组合式弹性元件,包括主扭矩件,设于主扭矩件两端的第一接头和第二接头,以及设于第一接头上的扭簧;所述主扭矩件为扭片组,或扭杆。该组合式弹性元件,结构简单、成本低,该组合式弹性元件内埋于折叠舵面,不影响气动外形,能够实现折叠舵不依靠改变其外形结构,实现大幅度提升初始扭矩,实现增大初始动能。
