摘　　要：开发了用非均匀有理B样条对叶轮机械叶片进行参数化三维重构的建模方法,成功实现了透平叶片、压气机叶片和风扇叶片的统一三维重构,并把该模块集成到了基于商业软件iSIGHT的气动优化平台中。在该气动优化平台上通过选择不同的优化策略,对一透平叶片分别进行了“基迭方式气动优化”和“全三维气动优化”,结果证明优化效果显著。A three-dimensional reconstruction system for turbomachine blades using non-uniform rational B-spline has been developed and demonstrated on a gas turbine blade, a compressor blade and a fan blade successfully. The three-dimensional reconstruction system has been integrated into the iSIGHT optimization system. Different kinds of optimization techniques in the optimization system were selected to achieve two types of turbine blade design experiments, stacking aerodynamic optimization experiment and three-dimensional optimization experiment. The result shows the optimization system effectable.
