Numerical Simulation of Heat Transfer and Chemistry in the Wake behind a Hypersonic Slender Body at Angle of Attack

Aerospace, 2018
The effect of thermal and chemical boundary conditions on the structure and chemical composition of the wake behind a 3D Mach 7 sphere-cone at an angle of attack of 5 degrees and an altitude of roughly 30,000 m is explored.

Robust multi-disciplinary design and optimisation of a reusable launch vehicle

, 2014
For various technical reasons, no fully reusable launch vehicle has ever been successfully constructed or operated. Nonetheless, a range of reusable hypersonic vehicles is currently being considered as a viable alternative to the expensive but more ...

Effect of a Roughness Element on the Receptivity of a Hypersonic Boundary Layer over a Blunt Cone Due to Pulse Entropy Disturbance with a Single Frequency

Entropy, 2018
A high-order finite difference method was used to simulate the hypersonic flow field over a blunt cone with different height roughness elements. The unsteady flow field induced by pulse disturbances was analyzed and compared with that under continuous ...

Characterisation of the USQ hypersonic facility freestream

, 2019
Hypersonic ground testing can make significant contributions to the design process for hypersonic flight vehicles. However, experimentation in conventional hypersonic ground testing facilities is complicated by the high levels of freestream fluctuations ...

SHEFEX-2 - Development Status of the Vehicle and Sub-Systems for a Hypersonic Re-Entry Flight Experiment

, 2009
The SHarp Edge Flight EXperiment (SHEFEX) is a DLR program to investigate aerodynamic behaviour and thermal protection problems of re-entry vehicles at hypersonic velocities, using unconventional shapes comprising multi-facetted surfaces with sharp edges.

Investigation of the Inverse Magnus Effect on a Rotating Sphere in Hypersonic Rarefied Flow

Applied Sciences
Explorations involving long-endurance and maneuvering flights in the upper atmosphere, as well as research on atmospheric entries of space debris or asteroids, call for a full understanding of hypersonic rarefied flows.

Experimental study of slender vehicles at hypersonic speeds

, 1996
An experimental investigation of the hypersonic flow over (i) a wing-body configuration, (ii) a hemi-spherically blunted cone-cylinder body and (iii) a one-half- power-law body has been conducted for M,, = 8.2 and Re,, = 9.35x104
