Design of an Internal Osculating Wave-Rider 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.

This paper presents the design of an inward-turning high-speed three-dimensional streamline-traced intake using osculating axisymmetric theory. The design criteria includes a stitched Busemann diffuser and internal conical flow-A solution for efficient compression, high flow uniformity, and straight leading-edge shocks of equal strength. A novel method for constructing the inlet cowl is also introduced. The validation of the design method is done through computational fluid dynamic results of the two-dimensional parent flowfields and the full three-dimensional design.
