Abstract/Summary Designing high-performance air intakes is of crucial importance for the successful operation of hypersonic scramjet propulsion. This paper investigates the flowfields and performance of axisymmetric intakes obtained by applying two shortening methods, namely, leading-edge truncation and stunting (longitudinal contraction), to the full Busemann intake. The aim is to balance viscous and shock losses so as to optimize performance and intake weight. The effects of intake shortening on performance are similar for the two methods for moderate (25%) decreases in intake length, conducing to considerable reduction in intake weight.
