Tests were conducted in the Aerodynamic Wind Tunnel (4T) using 0.05-scale models to investigate the separation characteristics of the M-117 retarded bomb, finned BLU-1C/B bomb, and SUU-42/A dispenser when released from various wing pylon locations on the A-7D aircraft. Captive trajectory data were obtained at Mach numbers from 0.33 to 0.95 at simulated pressure altitudes from 4000 to 7000 ft. The parent-aircraft angle of attack was varied from 1.8 to 12.3 depending on Mach number, climb angle, and simulated altitude. At selected test conditions, parent climb angles of -70 deg were simulated. In general, for the trajectory intervals of the test, most of the stores separated from the parent aircraft without store-to-parent contact. (Author)
