摘要
螺旋桨运转于舰艇艉后不均匀流场中,不均匀的流场对螺旋桨的空泡、噪声、振动以及水动力性能产生重要影响。而船舶螺旋桨适伴流理论设计及参数优化设计的目的就是在精确预报船舶艉后伴流场的条件下,合理地设计螺旋桨,使设计桨适合于所在伴流场下的运转。将伴流谐调分析法、螺旋桨侧斜及纵倾选择原则、升力线程序、升力面程序和非定常面元法程序、螺旋桨参数优化设计程序相结合,建立了螺旋桨适伴流理论设计及参数优化设计的系统,对大侧斜螺旋桨(highly skewed propeller,HSP)再设计为例,验证该系统的有效性。该系统为实现对潜艇螺旋桨的量身定制提供了理论支持。
The propeller is operated in the uneven flow field after the naval vessel, and the non-uniform flow field has an important influence on the vacuolization, noise, vibration and hydrodynamic performance of the propeller. The purpose of wake-adapted theory design and parameter optimization design of ship propeller is to reasonably design the propeller under the condition of accurately predicting the aft wake flow field, so that the designed propeller is suitable for operation under the accompanying flow field. In this paper, the system of the wake-adapted theory design and parameter optimization design of the propeller is established by combining the harmonic analysis method, the propeller side slope and the longitudinal inclination selection principle, the lift line program, the lift surface program, the unsteady surface element program and the propeller parameter optimization design program. Taking the redesign of highly-skewed propeller (HSP) propeller as an example, the effectiveness of the system is verified. The system provides theoretical support for tailoring the submarine propeller.
