A Numerical Evaluation of Hypersonic Inward-Turning Inlets at Off-Design Conditions
<p>The susceptibility of hypersonic, inward-turning inlets to performance losses at off-design conditions is explored. Axisymmetric, inward-turning inlets were designed for Mach 6, and the inlet performance was evaluated from computational fluid dynamics (CFD) simulations. These inlets were run at …
