| dc.description.abstractEn | The paper presents the results of an experimental study of the hydroelastic response of flexible lightweight hydrofoils undergoing various flow conditions including unsteady partial cavitating flow. It is based on the analysis of the static deformation, the vibrations, the strains and the stresses of cantilevered hydrofoils, at Reynolds number ranging from 3.10<sup>5</sup> to 6.10<sup>5</sup> in a hydrodynamic tunnel. A specific distance measurement laser device was used to measure the static deformation of the hydrofoil for bending and twisting. The vibration response was measured by means of two laser vibrometers in order to identify the modal response, mainly the first bending and twisting modes. The strains and stresses were obtained from integrated strain gauges imbedded in the foil close to the root section. A high speed camera was used in order to analyze unsteady features of the cavitating flow in some cases. The paper presents the experimental setup and the main results are discussed. | |
