带前置支撑导管桨导管脉动压力特性试验研究
|
摘要
应用微型脉动压力传感器对某带前置支撑导管桨航行器的导管脉动压力进行了测量,介绍了试验设备、试验方法和数据处理方法,并分析了导管脉动压力的频域特性,获得了脉动压力沿导管内壁周向和轴向的分布规律,以及水速、桨叶主参数对导管脉动压力的影响,可为推进器性能优化设计提供必要的数据支撑。结果表明:导管脉动压力线谱主要与桨叶叶频倍数相关,以一阶叶频为主;导管桨盘面处各周向测点脉动压力量值相当,无明显差异;轴向位置导管脉动压力在桨叶梢部弦长中点附近处最大,沿轴向随距离增加衰减迅速,且在导管出口段衰减比入口段更快;不同水速时导管脉动压力分布规律一致,随水速变大导管脉动压力迅速增加;桨叶直径与最大导管脉动压力之间线性关系显著。
Pressure fluctuation on the duct of a ducted propeller with pre-strut being behind a model ship was measured with micro dynamic pressure sensors. Experimental device, experimental method and the method of dealing with the data were described. Characters of fluctuating pressure on the inner face of the duct was analyzed in the frequency domain, and distributions along the circumferential direction and the axial direction were obtained. The influence of water speed and main parameters of the propeller on the fluctuating pressure was studied. The results show that the line-spectrum of fluctuating pressure is mainly related to the rotor's BPF, where the first BPF is a major component. Fluctuating pressures on all circumferential measuring points are well matched without significant differences. The fluctuating pressure on middle point of the blade chord is biggest and it decrease rapidly along the axial direction with the increase of distance from the propeller plane. The rate of decrease towards the outlet section is faster than that towards the inlet section. The distribution of fluctuating pressure in different water speed shows no difference, but the value of fluctuating pressure increases quickly with water speed. The linear relation between the propeller's diameter and the maximum fluctuating pressure on the duct is significant.
