摘要

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 5degrees angle of attack of the model combinations and at Mach numbers of 0.925, 0.950, 1.05,and 1.10in 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)
