In order to quickly determine the aerodynamic characteristics of the target aircraft,an efficient numerical analysis method based on 3D reconstruction technology is proposed.3D reconstruction in-tegrates the information of the three sided drawing extracts feature points and lines,and uses NURBS method to construct the surface.The rapid evaluation of aerodynamic characteristics is based on Euler e-quations,combined with GPU parallel technology,which can greatly improve computational efficiency.The accuracy of the numerical method is verified by the standard mode from subsonic to supersonic.Based on a certain triplane,reverse reconstruction and aerodynamic characteristics analysis were carried out.The results showed that the 3D reconstruction effect was good,and the numerical analysis method was effi-cient,which verified the good engineering practicality of the rapid analysis system established in this pa-per.
