The Development of High Order Numerical Techniques for Reentry Simulation of Hypersonic Spacecraft [PDF]

open access: yes, 1991
The primary difficulty encountered when simulating hypersonic flow is that the flow normally includes strong nonlinear discontinuities. These discontinuities fall into three broad classes: shocks, slip-lines, and rarefaction waves.

Aerodynamic Characteristics at a Mach Number of 6.8 of Two Hypersonic Missile Configurations, One with Low-Aspect-Ratio Cruciform Fins and Trailing-Edge Flaps and One with a Flared Afterbody and All-Movable Controls [PDF]

open access: yes, 1958
An investigation has been made to determine the aerodynamic characteristics in pitch at a Mach number of 6.8 of hypersonic missile configurations with cruciform trailing-edge flaps and with all-movable control surfaces.

AFFTC overview of orbiter-reentry flight-test results [PDF]

open access: yes, 1983
The Air Force Flight Test Center (AFFTC) has been participating in the flight testing of the Space Shuttle since 1976. An independent assessment of the reentry and landing capabilities of the Orbiter was conducted with respect to Department of Defense ...

Implicit High-Order Flux Reconstruction Solver for High-Speed Compressible Flows

open access: yes, 2018
The present paper addresses the development and implementation of the first high-order Flux Reconstruction (FR) solver for high-speed flows within the open-source COOLFluiD (Computational Object-Oriented Libraries for Fluid Dynamics) platform.

Analysis of Aerothermal Environment Characteristics of Hypersonic Rudder Shaft Gaps

open access: yes气体物理
Rudder shaft gaps of hypersonic vehicles affect the flow structure and corresponding aerodynamic heating characteristics, resulting in local peak heating near the rudder shaft, which poses a safety risk to the local thermal protection system.

Prediction of forces and moments for flight vehicle control effectors: Workplan [PDF]

open access: yes
Two research activities directed at hypersonic vehicle configurations are currently underway. The first involves the validation of a number of classical local surface inclination methods commonly employed in preliminary design studies of hypersonic ...

Transition Delay in Hypervelocity Boundary Layers By Means of CO₂/Acoustic Instability Interaction [PDF]

open access: yes, 2014
The potential for hypervelocity boundary layer stabilization was investigated using the concept of damping Mack’s second mode disturbances by vibrational relaxation of carbon dioxide (CO₂) within the boundary layer.
