Abstract:

A test was conducted in the Aerodynamic Wind Tunnel 4T to investigate the separation characteristics of the ALE-38 chaff dispenser from the F-4C and F-4E aircraft. Captive-trajectory store-separation data were obtained for four aircraftweapons loading configurations with store separations from the right-wing inboard pylon of the F-4C and F-4E aircraft. Data were obtained at Mach numbers from 0.42 to 0.90 at a simulated altitude of 5000 ft. At each test Mach number, data were obtained for both full and empty simulated store-model weights. The data obtained show that separation without parent-to- store model contact was achieved at all test conditions.
