Aircraft/store compatibility wind tunnel tests have been traditionally conducted without regard for the particular throttle-dependent inlet spillage condition which is simulated in the aircraft model. Tests were conducted in the AEDC 4-ft transonic wind tunnel Aerodynamic Wind Tunnel (4T) on a twin-engined, horizontal-ramped inlet fighter aircraft configured with air- to-air missiles and with provisions for simulating both maximum and cruise inlet spillage. The results indicate that for the missile carried nearest to the inlet, the carriage loads were as high as IOO% larger for the maximum spillage condition than for the cruise spillage condition. Jettison trajectories calculated for this missile indicate that the ejection forces dominate the early portion of the trajectory, and an significant difference was seen between maximum and cruise spillage conditions.
