Wind-tunnel investigation at low subsonic speeds of the static and oscillatory stability characteristics of models of several space capsule configurations
A 1960 NASA Langley technical report by J. L. Johnson, Jr., reporting low-subsonic wind-tunnel tests of static and oscillatory stability for several space capsule and escape-tower configurations, written for aerodynamicists and spacecraft engineers. Line drawings show sting-mounted capsules with wind vectors, pitch axes and hatched flow regions, plus contour plots of oscillation traces, alongside photographs of white escape-tower models against black and a technician inside a tunnel throat; usable as diagram vocabulary, silhouettes and high-contrast photographic stock.
