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 ...

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 ...

NASA built an X-42A hydrogen-powered scramjet to reach speeds of Mach 9.6 for a brief moment in 2004. Therefore, this new unmanned aircraft would be more of an optimization and refitting of an ...

Today, it takes 15 hours to fly from Sydney to Los Angeles. But what if that time could be shortened? What if crossing half the planet only takes one hour? How would we view the world? That’s the ...

Hypersonic vehicles have become the latest military prestige technology, and the US seems to be lagging its rivals. That could change after the successful flight of an autonomous and reusable ...

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 ...

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 ...

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 ...

Hypersonic weapons are frequently described as having unique, game-changing capabilities because they combine hypersonic speeds (more than five times the speed of sound, or Mach 5) with long-distance ...

Key Points - Despite billions invested in programs like the Air Force's HACM, Army's LRHW "Dark Eagle," and Navy's CPS, the United States currently has no operational, full-scale production hypersonic ...
