Parametric design of turbine blades based on feature modeling
-
摘要: 针对航空发动机涡轮气冷叶片的结构特点,提出了叶片参数化建模的特征分类形式.然后,利用特征造型技术开发涡轮叶片的参数化设计系统;并以直背涡轮叶片为具体实例阐述了该参数化模块的开发过程,为航空发动机典型结构件的参数化奠定了基础.Abstract: Considering the geometric features of the air-cooled turbine bladesof the aircraft engines, the methods to sort the features in the parametric modeling of the blades were advanced. A parametric design system was developed with feature-based modeling technology. The development of the parametric module wasinstanced by the parametric design of a straight-back air-cooled turbine blade, which is the basis of the parameterization of the configuration accessory in the aircraft engines.
