Parametric Three-Dimensional Modeling for Torpedo Contra-Rotating Propeller Based on UG OPEN/API

Optimization design of contra-rotating propeller is an important part in torpedo shape design.This paper pre-sents a parametric three-dimensional modeling method for contra-rotating propeller based on UG's second deve-lopment tools OPEN/API,and a parametric model of torpedo contra-rotating propeller is hence established.The modeling method can simplify the analysis process of optimization design of contra-rotating propeller.
