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

Investigation of Stability and Control Shortcomings of the North American X-15

Aerospace
There is growing interest in the design of maneuvering high-speed aircraft to fly within or at the edge of the atmosphere. We identify and develop novel quasi-static vehicle screening methodologies, suitable for use during preliminary design, to better ...

A surrogate-based flow-field prediction and optimization strategy for hypersonic thrust nozzle

AIP Advances
The thrust nozzle is a component that directly generates thrust, which is of great importance in the design of a hypersonic propulsion system. In this study, a surrogate-based flow-field prediction and optimization strategy for hypersonic thrust nozzles ...
