A Numerical Evaluation of Hypersonic Inward-Turning Inlets at Off-Design Conditions
… 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 a …

Boundary layer ingesting inlet design for a silent aircraft
… offsets lower than 11%. Curvature ahead of the inlet should be avoided as well as bifurcations inside the duct. Inlet performance with an evolved version of the airframe decreased, mainly due to a thicker boundary layer. Although further tailoring of the geometry is needed, the above guidelines …

Flow analysis and control in a subsonic inlet
S-duct inlets are commonly used on subsonic cruise missiles, as they offer a good compromise between compactness, low observability and aerodynamic performance. Though currently used S-ducts exhibit good performance in terms of distortion and pressure recovery at the AIP, the situation can degrade …

Non-Intrusive Sensing and Feedback Control of Serpentine Inlet Flow Distortion
… distortion intensity found in serpentine inlet airflow was established using wall-pressure fluctuation measurements. This sensing technique was experimentally developed for aircraft with serpentine inlets in a symmetric, level flight condition. The turbulence carried by the secondary flow …
