波浪滑翔机弹性水翼性能模型试验

波浪滑翔机的推力是由一组可以随着机体自动翻转的水翼来获得的。通过波浪水池模型试验对波浪滑翔机弹性水翼性能进行了研究,制作了波浪滑翔机水下牵引机的1:2.5缩尺模型,利用自制的垂荡激励拖车连接水下牵引机模拟在不同波高条件,分析不同情况下弹性水翼的性能。试验表明,波浪滑翔机水翼弹簧刚度应该根据工作海域的海况选取,海况较恶劣的海域波浪滑翔机弹性水翼可以选择较大的弹簧刚度;反之,水翼刚度不宜过大。

Investigation on the Efficiency of Elastic Hydrofoils of Wave Glider through Model Experiment

The propulsion of the glider is obtained via several automatically pitching hydrofoils.It is believed that adding elastic restraint to the hydrofoil of the wave glider can improve the efficiency of wave energy conversion.In this paper,model experiments were conducted to investigate this problem.The model of the submarine glider of the wave glider was designed and manufactured in 1:2.5 scale ratio.A self-made flume-based tractor pulling the submarine glider was designed to test the performance under different conditions.The results show that the spring stiffness of the wave glider hydrofoil should be selected according to the sea conditions.The elastic hydrofoil of the wave glider in the worse sea area can choose a larger spring stiffness.Otherwise,the spring stiffness of the hydrofoil in the milder sea area should not be too large.The experimental results also provide an important reference for choosing the stiffness of elastic hydrofoil of wave glider working in specific sea conditions.
