Abstract

In order to explore the methods of morphing aircraft variable-sweep and their aerodynamic characteristics, numerical simulation of the flow fields of a rotating variable-sweep wing-body and a shearing variable-sweep wing-body was conducted, and the aerodynamic characteristics and its mechanism were analyzed. Numerical simulation method of viscous compressible flow and hybrid grid of prism-hexahedron were used. The results demonstrate that: shearing variable-sweep has better characteristics than rotating variable-sweep in that the former has better lift-to-drag ratio and drag when flying at a speed in the range from M∞, 0.3 to M∞ 0.8, and the main reason is distinct flow field structure caused by the different variable-sweep methods.
