DRAG CHARACTERISTICS OF SEVERAL TWO-BODY SYSTEMS AT TRANSONIC AND SUPERSONIC SPEEDS
Abstract
The drag coefficients as well as the stagnation and base pressures of systems using an ogive cylinder or skirted hemisphere as primary body and a flat plate, 45 degree half-angle cone, sphere, and hollow hemisphere as secondary body have been measured at transonic and supersonic speeds. The Mach number range was from 0.85 to 1.25 and 4.35. Secondary body size and body separation distance were selected parameters. This is the fourth report in a series of studies dealing with the free stream drag and wake phenomena of bodies of revolution. With a few exceptions in the transonic range, the system drag was less than the sum of the free stream drag of the fore and aft bodies.
