Moreover, the rudder deflection angle matches reasonably with the balance angle of attack, so the ERGM has super glide ability.
舵偏角与平衡攻角匹配合理，有较高的滑翔增程能力；
Based on the built up rudder design principle, the paper proposes a practical optimal method for designing its balance coefficient.
基于船用组合舵的设计，本文提出了切实可行的平衡比优化设计方法，为选择合理的舵机功率提供了理论依据。
