摘要

A novel design method that is based on a local shape deformation technique is presented in this paper to extend the design space of waveriders. Moreover, an inviscid analysis based optimization study was carried out to research the effect of compression surface deformation on aerodynamic performances of waveriders by integrating the increment-based parameterization method, the computational fluid dynamic analysis, and the differential evolution algorithm. Afterwards, six selected waverider configurations were polished to blunt leading edges, and then their aerodynamic performances were evaluated by solving the Navier-Stokes equations. The results show that both the L/D and the relative pressure center coefficient of the waverider produce significant changes with the variation of compression surface shape. 漏 2017, American Institute of Aeronautics and Astronautics Inc, AIAA.
