Data Report for a Test Program to Study Transonic Flow Fields About Wing-Body/Pylon/Store Combinations. Volume I. Summary Report, Tunnel-Empty Flow Survey Data, Wing-Body Force/Moment/Surface Pressure Data, and Pressure Store Force/Moment/Surface Pressure Data.
Abstract
Results are presented for transonic wind tunnel tests conducted in the 4T Wind Tunnel at Arnold Engineering and Development Center for various wing-body/pylon store model combinations. Experimental data were obtained at 0,2, and 5 degrees angle of attack of the model combinations and at Mach numbers of 0.925, 0.950, 1.05, and 1.10 in the transonic range. Pylon and store models were attached to a wing-body combination in two separate, systematic model build-up sequences. At each stage of the first sequence, flow velocities and static pressures were obtained in the vicinity of the store or those regions normally occupied by a store while force, moment, and surface pressure measurements were taken on the wing-body model. Also, flow velocities and static pressure were recorded on a cylindrical control surface far from the tunnel centerline to provide outer flow field conditions. The second model build-up sequence involved a special pressure-instrumented store that was mounted on the captive trajectory system for simulating a separating store. Detailed pressure distributions and loading were obtained on the store. (Author)
