摘要

Variable-sweep wings are an important means to meet the flight characteristics of variable geometry missiles. In this paper, a variable-sweep wing structure for missiles was designed. First, a three-dimensional digital model of the wing structure was established. Then, based on the results of computational fluid dynamics simulations, an appropriate actuator was selected. Finally, computational fluid dynamics software was used to study missile models at various sweep angles, comparing and analyzing the aerodynamic characteristics at different speeds. The research summarized the patterns of the lift coefficient, drag coefficient, and lift-to-drag ratio as they change with sweep angle at different Mach numbers.
