Separation Characteristics of Six Stores from the A-7D Aircraft at Mach Numbers from 0.325 to 0.814

Abstract

Wind tunnel captive trajectory tests were conducted to investigate the separation characteristics of six stores from the wing pylons and racks of the A-7D aircraft. The stores tested represented possible combinations of munitions to be carried by the A-7D when performing search and rescue missions. Separation trajectory data were obtained for the loaded and expended SUU-23/A gun pod, CBU-12A/A, CBU-46/A LAU-3/A, LAU-68A/A, and the expended CBU-30/A. Trajectories were obtained at Mach numbers from 0.325 to 0.814 with aircraft angle of attack corresponding to level flight at 4000-ft altitude. For selected configurations, data were obtained to assess the influence of changes in the applied ejector forces during separation from the MAU-12B/A pylon rack. The stores separated without contacting the aircraft with only two exceptions.
