| 摘 要： | 为了减小赛艇航行中所受摩擦阻力,以改善其水动力学性能,提高运动员比赛成绩,提出了一种符合国际艇联规定的新型减阻技术.采用高压空气喷涂工艺,将涂料喷涂到赛艇表面,涂料固化后形成聚合物涂层.在深水拖曳水池中,分别对常规水力学光滑的赛艇和涂敷聚合物涂层的赛艇进行了阻力测试.测试结果表明,与常规水力学光滑的赛艇相比,涂敷聚合物涂层的赛艇所受摩擦阻力有所下降;随航速提高,摩擦阻力下降的绝对值呈增长趋势,聚合物涂层的减阻效果更加明显。

| Abstract: | In order to enhance the dynamics performance of rowing shell,a kind of polymer coating was proposed for skin friction drag reduction.The rowing shell was coated with a mixture through self-developed spray-painting system,and micro-structured polymer coating formed spontaneously on rowing shell surface after the mixture solidified.To evaluate the drag reduction property of polymer coating,comparison experiments between coated rowing shell and smooth rowing shell were performed in a deep towing tank,respectiv... |
