局部气垫双体船阻力与航态性能试验研究
Experimental study on resistance and navigation state of partial air cushion support catamaran
摘要
Abstract
To verify the sailing performance of partial air cushion support catamaran (Pacscat ) ,the resistance characteristic and navigation state of the Pacscat were investigated .Based on model tests , the values of resistance ,heave and trim in different displacements and center of gravity locations were measured and then the change law of Pacscat′s resistance and navigation state was obtained .The re‐sults show that when the air cushion Froude number is less than 0 .8 ,hull resistance will decrease with inflatable flow of air cushion and the resistance peak will be reduced and appear advance mean‐while .On the contrary ,when the speed is larger ,hull resistance will decrease with inflatable flow of air cushion′s increasing .Meanwhile ,the Pacscat′s resistance performance will be improved by the in‐creasing of longitudinal center of gravity .In addition ,after crossing the peak ,the Pacscat can reach the planning condition immediately with better rapidity and longitudinal stability for the special plan‐ning surface .关键词
