Hypersonic flight, with speeds exceeding Mach 5, pushes the boundaries of engineering. But as vehicles slice through the atmosphere at these incredible velocities, complex interactions occur between ...

The study of hypersonic inlet aerodynamics and flow dynamics encompasses a diverse field where extreme speeds, intense thermal loads and complex shock–boundary layer interactions coalesce to define ...

Hypersonic flow testing and measurement techniques form a critical component in advancing our understanding of high-speed aerothermodynamics. Researchers utilise a variety of specialised ...

Contours of normalized temperature perturbations of optimal responses inside the boundary layer and the entropy layer, and these optimal responses may shift to another type as a change of specific ...

A close look at air flow around high-speed shapes reveals surprising turbulence, according to a new study. The findings, published March 7 in the journal Physical Review Fluids, could inform the ...

A promising technique for tracking boost-glide hypersonic vehicles involves detecting radio waves emitted by plasma in the wake. Passive detection would be a valuable capability, since existing ...

The Boundary Layer Transition 1B (BOLT-1B) experiment, a joint research project of the U.S. Air Force Research Laboratory (AFRL), the Johns Hopkins Applied Physics Laboratory (APL), and the German ...

February 13 2025, the Defense Advanced Research Projects Agency (DARPA) announced its secretive Aerospace Projects Office (APO) is developing a large hypersonic bomber prototype as part of the Next ...

Speed is paramount in designing missiles, so engineers have worked for years to improve how fast a missile can fly. The goal is to strike a target without warning, so the faster an object, the harder ...
