Abstract:

An investigation of the aerodynamic characteristics of a family of ring tail strut-body configurations was conducted at Mach numbers from 0.80 to 4.5. Rings varying from 1.25 to 2.50 calibers in diameter and from 0.60 to 1.50 calibers in length were tested. They were tested at various longitudinal positions and with internal expansion angles from 0 to 6 degrees. The effect of changing from circular section support struts to streamlined struts was also investigated. This report presents the zero-lift foredrag and base drag results and compares them, wherever possible, with theoretical estimates.
