ON CONCAVE BODIES IN FREE MOLECULAR FLOW,

Abstract

Data on drag of concave surfaces are represented. 'Unshielded' concave surfaces are considered, for which the entire surface is exposed to the incident free molecule flow. The effect on free molecule drag of shielding a portion of the concave surface from the incident flow is illustrated. From a practical point of view, free molecule flow over concave bodies is of interest for possible applications including parachute-like drogue devices, high altitude air collectors or induction systems for propulsion systems, pressure probes, etc.
