Abstract

Full-scale flight base pressure coefficients obtained from the XB-70 propulsion package are compared with predicted values based on a combination of cold jet flow wind-tunnel models and data from a two-engine side-by-side jet, full-scale aircraft. At cruise Mach numbers the base pressures on the full-scale aircraft were higher than predicted, resulting in a favorable increment of about 2 percent in terms of lift-drag ratio.
