摘要
针对水下目标壳体复合涂层减阻应用需求,分析水下目标壳体阻力计算方法,设计试验模型结构与安装形式,并仿真分析了粗糙度对阻力影响;提出5种壳体复合涂层试验方案和方法并开展复合涂层阻力试验,对比分析各复合涂层方案总阻力、阻力系数和减阻率。试验结果表明:PU+6%SiO_(2)复合涂层方案虽然表面粗糙度高于光体和光滑油漆方案,但其在水下目标试验航速小于9m/s时的减阻效果较好。
According to the drag reduction demands on composite coating of underwater targets shell,the drag calculation methods,the experimental model parameters,structure and installation form were analyzed.The influence of roughness on resistance is simulated.Five composite coating schemes,and experimental methods and steps of shell were put forward.The drag test of composite coatings were carried out,and the total drag,drag coefficient and drag reduction rate of each composite coating scheme were compared.The test results show that,although the surface roughness of PU+6% SiO_(2) composite coating scheme is higher than that of bare body and smooth paint scheme,its drag reduction effect is better when the underwater target experimental speed is less than 9 m/s.
