The Development of Rapid Predictive Methods for Three-Dimensional Transonic Flow Fields About Fighter Bomber Aircraft. Part I.
Abstract
This report presents an overall account of the progress made on an essential component of the transonic store trajectory problem: the predicton of transonic flow fields about wing-body/pylon combinations representative of modern fighter-bomber aircraft. The emphasis here is on the development of predictive techniques which are sufficiently economical from the standpoint of computer cost to enable an aircraft designer to employ the techniques over a wide range of Mach number, angle of attack, and geometric parameters. The report presents several candidate transonic predictive methods and evaluates them by comparing their predictions of various flow field quantities with experimental data. The experimental data are taken from a parallel wind-tunnel test phase of the project, designed specifically for evaluating the predictive methods. The experimental data have been documented and archived in several test reports. The extensive comparisons of the theoretical predictions from the various predictive methods with the data comprise the major portion of this report.
