Design of Hypersonic Inward-Turning Inlets

摘要

A family of dual-axis compression, high-contraction-ratio, inward- turning inlets has been designed to achieve a desired shock structure and aerodynamic performance at Mach 6. Computational simulations of the internal inlet flowfield were performed using the research code FDL3DI. These solutions are an integrated part of the inlet design methodology and offer insight into the fundamental fluid phenomenology. The effects of viscous/inviscid interactions, namely swept-shock/turbulent boundary layer interactions are discussed. Additionally, the importance of complementary computational fluid dynamics (CFD) to the experimental work as part of the integrated hypersonic inlet design process is also addressed.
