A wind-tunnel investigation was carried out on an oscillating model of the F-5 wing with and without an external store (AIM-9J missile). The store was mounted at the wing tip as well as at a pylon underneath the wing. Detailed steady and unsteady pressure distributions were measured over the wing, while on the store aerodynamic loads were obtained. In addition, wind-tunnel wall pressures were recorded. The tests covered the Mach number range between Ma = .6 and 1.35, and frequencies up to 40 Hz. This report gives an analysis of the results of the configuration with the store mounted at the wing tip. Emphasis is put on the influence of the store on the wing loading and further on the store loads. A comparison is presented of experimental data and theoretical results obtained with the unsteady NLRI and Doublet Lattice methods. (Author)
