Abstract:

Tests were conducted in the Aerodynamic Wind Tunnel 4T using 0.05- scale models to investigate the separation characteristics of modular weapon configurations with different nose and tail geometries when released from various positions on the triple ejection rack at the wing inboard pylon location on the F-4C aircraft. Captive trajectory data were obtained for level flight at Mach numbers 0.6, 0.9, and 1.2 at a simulated altitude of 5000 ft. The parent aircraft angle of attack was varied from 0.1 to 2.4 deg, depending on Mach number. In general, for any nose and tail combination, the effect of increasing Mach number was to produce a more negative nose down initial pitch rate. For the configurations tested, and over the Mach number and trajectory intervals of this test, the modular weapon with a hemispherical nose and conical boattail appeared to be the most suitable store for separation without store-to-parent contact.
