| description | The invention discloses a full-three-dimensional modeling method and device for a high-performance turbomachine blade and electronic equipment. The method comprises the steps that S1, according to an airflow angle along a meridian streamline obtained through calculation of an axisymmetric flow field and according to a thickness distribution rule given by experience, preliminary modeling is conducted on a meridian streamline rotation flow surface; s2, the speed parameter distribution rule of the suction surface and the pressure surface of the blade profile is calculated through a blade streaming calculation method, iteration is conducted on the speed parameter distribution rule and the initial model, and the optimal blade profile surface on each rotation flow surface is obtained; and S3, a Conus curved surface method in the differential equation is introduced to carry out splicing, total curvature inspection and curved surface fairing on the molded surfaces of all the blade profiles, it is guaranteed that the |
