Near-Free Molecule Drag of Slender Cones.

D. R. Willis

Expert InsightsPublished 1970

A systematic theoretical and empirical framework for the study and correlation of aerodynamic drag information is an important application of the methodology of rarefied gas dynamics. This paper considers a flight regime for a slender pointed cone, where there appear the first effects on drag of intermolecular collisions between freestream molecules and gas molecules that have already struck a body surface. Thus, the phenomena discussed here correspond to hypersonic reentry into the upper atmosphere, where the first corrections to the traditional free-molecule drag coefficient are likely to be significant. 58 pp. Ref.
