The study of hypersonic boundary layer transition and instability encompasses the complex processes by which a thin, near-wall flow region shifts from a smooth, laminar state to a highly chaotic, ...

Learning from an anomaly during the first BOLT-1A flight, the successful BOLT-1B follow-on flight experiment collected ...

Hypersonic boundary layer dynamics and stability form a critical research area with implications for the design and operation of high-speed aerospace vehicles. At speeds exceeding Mach 5, the ...

Abstract: An improved understanding of the interactions between fluid dynamics and thermal non- equilibrium (TNE) effects, which result from strong shocks, is critical in developing improved thermal ...

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 ...

Chris James receives funding from the University of Queensland, the Australian Research Council, and the U.S. Office of Naval Research.. The BOLT II hypersonic flight experiment will launch tonight ...

The BOLT II “In memory of Mike Holden” flight experiment, managed by the Air Force Research Laboratory/Air Force Office of Scientific Research, launched on the evening of March 21 from the National ...

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 ...

At hypersonic speeds, complexities occur when the gases interact with the surface of the vehicle such as boundary layers and shock waves. Researchers were able to observe new disturbances in ...

The U.S. Air Force's Arnold Engineering and Development Center (AEDC) is conducting tests of a hypersonic boundary layer transition (HyBOLT) rocket model in a wind tunnel at the von Karman Gas ...

The Missile Defense Agency (MDA) and Space Development Agency (SDA) are currently developing elements of a missile defense system that may be able to defend against hypersonic weapons and other ...

ORLANDO, Fla. – Preliminary findings of an investigation into the August 2008 loss of NASA’s HyBOLT (hypersonic boundary layer transition) rocket-boosted experimental project suggest a software fault ...
