Abstract
The article describes experimental studies of hydrodynamic qualities of surface-piercing propellers (SPP). The experimental studies require the application of specific cavitation basins or cavitation tunnels with free surface in the working area. The article describes the modernization of the existing cavitation tunnel to meet the requirements to free surface and to perform SPP tests. The modernization includes the installation of the stand specifically designed with a plate guiding the flow. Eventually, it helps create free surface in the working area. The modernization offered will allow to perform SPP testing. The application of the stand in cavitation tunnel installed in St. Petersburg State Marine Technical University has confirmed the possibility of such modernization..
Keywords: surface-piercing propellers, stand, experimental investigation.
