实船快速性能预估方法及试验验证

Fast Performance Prediction Method for Full-scale Ship and Test Verification

为了能在设计阶段准确地预估实船快速性能,以某船型为具体研究对象,先后开展阻力试验、螺旋桨敞水试验和自航试验。根据船模试验结果,按照1978 ITTC单桨船实船性能预估方法分别计算实船阻力、螺旋桨敞水性征曲线、自航因子以及各种推进效率成分,并绘制航速功率关系曲线图。通过实船试航试验对计算结果进行验证,结果表明:应用1978 ITTC方法预估的实船航速结果和实船试航试验结果较为一致。

In order to accurately predict the fast performance of the real ship in the design stage,taking a ship type as the specific research object,resistance test,propeller open water test and self navigation test have been carried out successively.According to the results of ship model test,the real ship resistance,propeller open water characteristic curve,self navigation factor and various propulsion efficiency components are calculated according to the 1978 ITTC single propeller ship real ship performance prediction method,and the speed power relationship curve is drawn.The calculation results are verified by the real ship trial test.The results show that the real ship speed predicted by the 1978 ITTC method is consistent with the real ship trial test results.
