Summary Of Hypersonic Boundary-layer Transition Experiments On Blunt Bodies With Roughness

摘要

Laminar-turbulent transition on the Crew Exploration Vehicle (or Orion) is likely to be dominated by the effects of ablation and the laminar-ablated roughness, both isolated and distributed. Although no single ground experiment can simultaneously duplicate all aspects of this complex process, many experiments have been carried out using roughness applied to nonporous models without blowing. The present paper reviews these data for the effect of roughness on hypersonic blunt-body transition.
