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 ...

Designing a thermal protection system to keep astronauts and cargo safe requires an understanding at the molecular level of the complicated physics going on in the gas that flows around the vehicle.

The boundary layer stability analysis with a concave wall is termed the Görtler instability. It has been shown in this study that, apart from the conventional wall-layer mode (mode W) there also ...

Hypersonic flow and shock wave dynamics represent a critical domain in aerospace science, where the physics of high-speed fluid motion are explored under extreme thermodynamic and chemical conditions.

Using data collected in a NASA Langley Mach 6 wind tunnel, researchers at the University of Illinois Urbana-Champaign replicated the hypersonic flow conditions of a compression ramp flow by means of ...

Abstract: At hypersonic speeds, vehicles experience extreme heating that drives ablation of thermal protection systems, where protective materials erode, releasing gases and particulates into the flow ...

A groundbreaking simulation study led by researchers at the University of Illinois Urbana-Champaign has uncovered never-before-seen flow instabilities around hypersonic vehicles traveling at Mach 16, ...

While studying the chemical reactions that occur in the flow of gases around a vehicle moving at hypersonic speeds, researchers use a less-is-more method to gain greater understanding of the role of ...
