摘要
以圆锥绕流流场为基础,运用锥导理论生成了不同的乘波机构型,并对乘波机进行了包括升力、粘性阻力、波阻、升阻比、乘波机长度、体积、容积效率等各主要性能指标在内的性能计算,初步确定出了锥导乘波机性能的变化规律及其决定性定型参数。计算结果表明:锥导乘波机构成方法简单且具有较高的升阻比和反设计性能,源流场圆锥半锥角、乘波机上表面型线曲率半径是影响锥导乘波机性能的决定性定型参数。
The hypersonic flow past a cone was calculated. Waverider configurations are generated by Cone-Derived. The primary performance of waverider including lift, friction drag, wave drag, lift-to-drag ratio, length, volume, volumetric efficiency etc, was calculated. Investigation shows that the Cone-Derived waverider have high lift-to-drag ratio and excellent inverse-design performance, semivertex angle and the flow capture curve's curvature radius are the two most important parameters which play important role on the Cone-Derived waverider performance.
