摘要

从接触轴对称理论出发，提出了高速内旋三维流线进气道的设计。为了满足同步进气设计标准，采用缝合的Busemann扩压器和内部的锥形流- a解作为基本等熵压缩流线。这种新的轮廓提供了有效的压缩，高流动均匀性，并直接前缘冲击等强度。此外，还提出了一种新型的进气罩结构方法。这种组合工艺为高速进气设计提供了一种新的方法。建造了一个通用的形状转换入口，并将其命名为印第安纳入口，以纪念为该项目做出贡献的印第安纳大学。计算流体力学结果验证了二维母流场设计方法和全三维设计方法。

Design of an Internal Osculating Waverider Intake

The design of an inward-turning high-speed three-dimensional streamline-traced intake is presented from osculating axisymmetric theory. To satisfy the osculating intake design criteria, a stitched Busemann diffuser and internal conical flow-A solution are used as the basic isentropic compressive streamline. This new contour provides efficient compression, high flow uniformity, and straight leading-edge shocks of equal strength. Additionally, a novel method for constructing the inlet cowl is presented. The combined process leads to a new method of high-speed intake design. A generic shape-transitioned intake is constructed and named the Indiana inlet for the Indiana universities that contributed to the project. Computational fluid dynamic results are assessed to validate the design method for the two-dimensional parent flowfields and the full three-dimensional design.
