潜水面舰艇（SSS）是一种利用机翼向下升力并保持剩余浮力以安全避开汹涌海面的新型概念舰艇。提出了一种由船体、一对主机翼和一对水平尾翼组成的SSS原型，其中主船体和桥甲板的形式用数学公式表示。圆周运动试验阐明了作用在SSS原型模型上的水动力和力矩在垂直和横向运动中的特性。坦克试验揭示了主翼和尾翼角度如何影响总水动力和力矩，以及它们的性能如何相互作用。试验数据还反映了不同淹没深度和不同桥面纵向位置的水动力特性变化。将估计的线性水动力导数与试验数据分析结果进行了比较，验证了估计方法的有效性。建立了一个数学模型来描述观察到的现象，即副翼角在横向运动中诱导垂直力和俯仰力矩，从而导致原型SSS的垂直和横向耦合运动。
The submersible surface ship (SSS) is a new concept ship that avoids rough seas by going underwater using downward lift of wings and keeping residual buoyancy for safety. A prototype of SSS consisting of a hull, a pair of main wings, and a pair of horizontal tail wings is proposed, where mathematical formulae represent the forms of main hull and bridge deck. The circular motion test clarified the characteristics of hydrodynamic forces and moments acting on a model of the prototype SSS in vertical and lateral motions. The tank tests revealed how the main and the tail wing angles affect the total hydrodynamic forces and moments as well as how their performance interact each other. The test data also tell the variation of hydrodynamic characteristics of different submerged depth and different longitudinal position of the bridge deck. Comparisons of the estimated linear hydrodynamic derivatives with those obtained by the test data analysis validate the estimation method. A mathematical model is presented to describe the observed phenomenon that the aileron angle in lateral motion induces the vertical force and pitch moment, which leads a coupled vertical and lateral motion of the prototype SSS.
