Analysis of Hydrodynamic Characteristics of Water-drawing Efficiency for Seaplanes
In order to evaluate the water-drawing performance of a seaplane,a study on the water-drawing efficiency of a scaled model was carried out,and the variation law of the water-drawing efficiency was quantitatively analyzed.Under the condition of fixed attitude and considering free surface,the correlation between different scale models is studied,and the influence of scale ratio on the water-drawing efficiency is analyzed,and the actual water-drawing efficiency is calculated and analyzed.The water-drawing efficiency and flow field characteristics of the seaplane during swabbing and taxiing are obtained through numerical simulation and pool test.Compared with the numerical simulation results and pool test results,the variation trend with speed is basically the same,the flow field characteristics are basically the same,and most of the calculation errors of the water-drawing efficiency are within 10%,indicating that the numerical simulation accuracy is high,and it is feasible to use this method to predict the swabbing efficiency.The research results have certain guiding significance for the study of the water-drawing performance of seaplanes.
