摘要
为了研究多航态高速无人艇在不同吃水航态下的阻力性能以及运动特性,在半潜到水面航态范围内变换6个吃水状态进行模型阻力试验,试验速度涵盖排水航行到滑行状态范围,对每个吃水工况下的航行姿态、阻力性能进行分析研究。结果表明,该多航态高速无人艇在一定吃水范围内都有着较好的阻力性能以及良好的运动姿态,在中低速(Fr■<2.0)条件下,该模型在不同吃水下的运动姿态、阻力性能随航速的变化趋势一致,但在高速滑行(Fr■>3.0)条件下变化趋势有差异;剩余阻力占总阻力的比例Rr/Rt随着吃水的增加而不断增大,在相同吃水条件下Rr/Rt随着Fr■的增加呈现出先增大后减小的规律。
In order to study the resistance and motion characters of the multi-navigation high-speed craft under different draft conditions,a series of towing resistance model tests were conducted by changing draught conditions from semi-submerged state to surface-navigation,the test speed covers the drainage sailing state to high speed planing condition.The sailing state and resistance characters of different draft condition was studied.The results show that this craft has good resistance characters and good movement posture within a certain range of draught.With the Fr■<2.0 condition,the trend of movement attitude and resistance performance are the same under different draught conditions,though they show difference under the Fr■>3.0 condition.The ratio of residual resistance to the total resistance Rr/Rt increases with the draught.Under the same draught conditions,Rr/Rt shows a trend that increases first and then diminishes with the increase of Fr■.
