Abstract:

Aerodynamic force and moment measurements were made on 0.05-scale models of the M-117GP and BLU-1CB bombs, the 300-gal fuel tank, and the AGM-62A Walleye missile in the carriage position on the A-7D and F-4C aircraft at Mach numbers from 0.5 to 2.0. The aircraft model angle of attack was varied from -4 to 12 deg and the yaw angle from -8 to 8 deg. Studies were made to evaluate the effects of store nose shape variation and store location on the multiple ejection rack and pylon on the measured aerodynamic coefficients. This report contains a description of the test along with information to identify test configurations and test conditions for all data obtained. Only a limited amount of data is presented to show the magnitude of the store aerodynamic loads and variations caused by changes in the aircraft configuration.
