摘要

摘要: 操纵空化器转角是超空泡航行器姿态控制的常用手段之一, 为进一步研究空化器操纵过程中空泡和水动力特性, 文中通过精细计算和分析优化, 提出并建立了一种空化器操纵过程非定常水动力测量的水洞试验模型和方法。通过在试验模型内部紧凑布置直线电机、位移传感器、压力传感器、传动系统、通气系统以及测力天平, 实现了对空化器转角的操纵以及泡内压力和水动力测量功能, 静态工况空化器水动力测量结果与经验公式结果对比, 证明了该试验方法的有效性。

Abstract: Cavitator is one of the main devices for the attitude control of a supercavitation vehicle. By precise calculation and optimization, a water tunnel test model is designed and an unsteady measurement method of hydrodynamics in the water-tunnel is proposed for the cavitator control process. The control of the cavitator, as well as the measurement of pressure inside cavity and hydrodynamics, is realized in the condition of compact arrangement of the linear motor, displacement sensor, pressure sensor, transmission system, ventilation system and force balance inside the test model. The test method is verified by comparison between the results from test and empirical formula in static condition.
