沿海高速双体搜救艇水动力性能试验

摘要

In order to meet the request that the search and rescue ship arrive at the accident location in the first time when ships come across the accident near the coast, and complete the task like survey the scene or secure people from the accident, we design two types of catamaran. We select the type performance in better resistance and compare with a catamaran test date of seakeeping, predict the hydrodynamic through 1TTC wave spectrum, proved that this ship style adapt the condition of coastal sea and meet the daily tasks.%为了满足沿海船只发生海损时,搜救船舶应能第一时间到达事故发生位置,并且完成勘察现场、事故人员救助的任务,设计了2种线型的双体搜救艇.通过船模阻力试验选出阻力性能较优的一种,对其进行耐波性分析,与某双体船试验数据进行对比,并用ITTC双参数谱预报了实船耐波性,验证了该船型能满足沿海海况和日常任务的需求.
