This is the final report of a series investigating the stability and drag characteristics of sounding rocket payloads. The purpose is to study the factors which will allow slowing the vehicle sufficiently to facilitate an air snatch recovery. Geometry is one of the parameters varied by considering truncation of the cylindrical portion of the payload along its longitudinal axis. The present report gives a summary of previous experimental and theoretical work in the series. In addition, simple relations are developed using a modified Newtonian theory to enable prediction of drag in hypersonic flows including those in a rarefied atmosphere.
