Separation Trajectories for the SUU-51B/B Store from the F-4C Aircraft
Abstract
Separation trajectory data were obtained to investigate some possible ways to reduce the nose-down pitch of the SUU-51B/B store during separation from the Triple Ejection Rack (TER) on the F-4C aircraft. Data were obtained to assess the influence on the store separation characteristics resulting from (1) changing the store mass properties (ballasting), (2) modifying the TER geometry to represent removal of the nose fairing, (3) changing the store carriage location on the TER, (4) modifying the store nose geometry, and (5) applying dual ejector forces to the store during separation. Separation trajectories were obtained for release from the TER on the inboard pylon at Mach numbers from 0.66 to 1.1 for level flight at 5000-ft altitude. In addition to the trajectory data, force and moment data were obtained on the SUU-51B/B to assess the influence on store loads of (1) changes in store position relative to the rack, and (2) the modified nose geometry. Results of the test show that the dual ejector forces were most effective in reducing the store nose-down pitch. Separation of the ballasted store from the modified TER produced the best results of all combinations using the single ejector.
