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 ...

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 ...

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 ...

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 ...

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 ...

Stratolaunch has finally found a use for the world’s largest airplane. Twice in the last five months, the company launched a hypersonic vehicle over the Pacific Ocean, accelerated it to more than five ...
