THE DRAG OF CONES, PLATES, AND HEMISPHERES IN THE WAKE OF A FOREBODY IN SUBSONIC FLOW

Abstract

The drag of a number of bodies having some resemblance to aerodynamic deceleration devices was measured in free stream and in the wake of an ogival cylinder. The diameter ratio of the wake producing and the deceleration devices as well as the distance between the two bodies was varied. With the exception of the sphere, the drag of the deceleration device located in the wake is less than its free stream drag.
