This paper examines the recent assignment of U.S. Air Force civil engineers to joint missions, across the range of military operations, in order to forecast the feasibility and suitability of continuing this practice in the future. Air Force engineers have been extremely effective in joint combat support roles, since their substantial joint combat use beginning in 2004. Based on this success, their demand has grown and will likely grow beyond ...
Analytical and experimental studies of ablative material performance for solid rocket nozzle applications were performed. Large scale computer codes were employed to calculate the ablation, thermal, and structural responses of the 260-SL-3 nozzle as a design check and as a basis for post- fire analysis. The calculated performance included consideration of surface chemical reactions, melt removal, particle deposition, char swelling, in-depth kinetic decomposition, and anisotropic mechanical and thermal Properties. Laboratory ...
