Three-Dimensional Reconstruction And Aerodynamic Characteristic Analysis Of The Large Civil Aircraft B787

In decades, with the dramatic development of aeronautics and astronautics, CFD (Computational Fluid Dynamic) is widely used in the aerodynamic design of aircraft due to the efficiency and applicability. CFD as well as the wind tunnel, and the flight-test, becomes one of the most three significant methods in the aircraft design.This paper presented the 3-D model of Boeing 787 with outstanding streamed characteristic by utilizing the multi-angle reconstruction theory, a straight trailing-edge wing model was also designed based on the original model of Boeing 787 for the analysis of the streamed wing characteristic. Numerical simulation was employed in the two models above; the mechanism of the different flow behaviors of the two models can be analyzed by CFD. The study aimed to provide the valuable reference to the practical engineering. Increasingly, the Chinese government and industry organization investigate plenty of funds to the aeronautic industry especially the large civil aircraft which leads a precious opportunity to promote the national power. Therefore, through the 3-D reconstruction and aerodynamic analysis to study the mechanism of the dominate points of the classical large civil aircraft in the world is of great value.
