摘要
为了设计出高效节能的对转桨,采用螺旋桨的旋涡理论分别对前桨和后桨进行设计,前桨和后桨之间的相互影响通过诱导速度来考虑,并用面元法分别进行水动力性能预报.通过实例设计分析发现:在设计进速条件下,该方法设计的对转桨与设计的单桨相比效率可提高10.24%;在一定进速范围内,进速系数越大对转桨节能效果越佳.
In order to obtain comprehensive design and investigation of the contra-rotating propeller, the propeller vortex theory was adopted to design the forward and the aft propeller respectively.The interaction between the forward propeller and the aft propeller was considered through the induced ve-locities and the surface panel method was used to predict the hydrodynamic performance off the sys-tem.The analysis of an instance shows that at design advance speed,the contra-rotating propeller de-signed through this method can raise the efficiency by 10.24% compared with the single propeller de-signed through the same method.After further analysis of the designed contra-rotating propeller,it is known that the energy saving effect is better at higher advance speed within a specific range.
