A first order structural optimization problem is examined to evaluate the effects of structural geometry on blast energy transfer in a fully coupled fluid structure interaction problem. The fidelity of the fluid structure interaction simulation is shown to yield significant insights into the blast mitigation problem not captured in similar empirically based blast models. An emphasis is placed on the accuracy of simulating such fluid structure interactions and its implications on designing continuum level structures. Higher order design methodologies and algorithms are discussed for the application of such fully coupled simulations on vehicle level optimization problems.
Posturing Fire Supporters to Utilize Naval Surface Fire Support by MAJ John C. Goetz II, US Army, 52 pages. This monograph determines whether the US Army is sufficiently training, organizing, and equipping fire support elements to utilize naval surface fire support. Its scope is restricted to fire support elements in airborne, air assault and light infantry units. This study came as a result of the Marine Corps' decision to deactivate their ANGLICO units, which had habitually provided the expertise to Army forced and early entry units to utilize naval surface fire support. Without these units, the Army must rely on its organic fire supporters to request and control naval fires. To accomplish this, they must first be properly trained, organized, and equipped. This topic becomes increasingly important as the Army moves to a force projection structure. The Army has put enormous strain on its own helicopter lift as well as the Air Force's strategic lift assets. To preclude having to use these assets to initially transport artillery and ammunition to support early ground maneuver, the Army must prepare to use naval fire support when available. The Navy is currently developing a suite of systems to provide naval fire support to support Marine Corps Operational Maneuver from the Sea doctrine. The Army must plan now to utilize these systems in the future. The monograph studies the historical aspects of naval gunfire and the units that were created to request it. This leads into a study of training, organization, and equipment of both ANGLICO and Army fire support elements to determine critical variances between them that would limit the Army's ability to control naval surface fires. Major findings show that while the Army is organized properly to perform this mission if manned at 100 percent strength, current equipping and training of fire support elements is inadequate. Equipment shortfalls are being addressed in the near term by installation of SINCGARS on Navy ships. In the long term, the future fielding of the Joint Tactical Radio System will ensure joint communications compatibility well into the future. Training shortfalls can be addressed by effectively using existing Marine Corps Schools and Mobile Training Teams to train personnel in key positions such as JRTC and BCTP O/Cs. In addition the resident Marine Corps Detachment at Fort Sill must continue to be utilized to instruct Army fire supporters in career progression schools.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
