N2 - Axisymmetric and streamtraced Busemann hypersonic inlets are studied in detail for Mach 10 flight at 30 km altitude conditions. Numerical simulations are performed to study the effects of truncation angle, leading edge bluntness, boundary layer growth, inlet crosssection, and leading edge shape on inlet performance parameters. Simulations of the axisymmetric Busemann inlet show that for Mach 10 flight, truncations angles should kept between 2° and 4°, leading edge radii should be kept small (∼1 mm), and boundary layer corrections should be based on 50% of the displacement thickness. Additionally, inlet frontal profile and leading edge shape are found to significantly impact inlet performance and efficiency.
