在具有余摆线叶片运动的摆线型螺旋桨模型上进行了开阔水面实验。该螺旋桨有三个叶片，纵横比为10。这些实验包括在一定的前进比范围内测量螺旋桨的推力和扭矩。试验进行了正向和反向操作，并在零速度（系船柱拉力条件）。这些试验的结果被提出和比较：螺旋桨性能的多流管理论预测;和螺旋桨的单个叶片的性能的预测，在升沉和俯仰中振荡，使用非定常小振幅水翼理论，并对有限振幅运动、有限翼展和摩擦阻力进行校正
Open-water experiments were done on a model of a cycloidal-type propeller with a trochoidal blade motion. This propeller had three blades with an aspect ratio of 10. These experiments included the measurement of thrust and torque of the propeller over a range of advance ratios. Tests were done for forward and reverse operation, and at zero speed (the bollard pull condition). Results from these tests are presented and compared with: a multiple stream-tube theoretical prediction of the performance of the propeller; and a prediction of the performance of a single blade of the propeller, oscillating in heave and pitch, using unsteady small-amplitude hydrofoil theory with corrections for finite amplitude motion, finite span, and frictional drag
