Book excerpt: A combined theoretical and experimental research program has been carried out over the past four years to establish preliminary design criteria for estimating the aeroelastic stability and forced-response characteristics of thin-walled circular cylindrical shell structures. As a result of this study, several basic observations were made concerning the degree of sophistication required in the aerodynamic and structural modeling of this aeroelastic problem. It was found, for example, that small details in the description of the structural boundary conditions can strongly influence the aeroelastic stability of the shell. The most significant structural boundary condition effect was observed when the shell geometry and loading conditions were such that the edge disturbances were propagated well into the interior of the shell. On the other hand, when conditions were such that these edge disturbances were confined to a small boundary layer region near the ends of the shell no significant edge effects were noticed on the overall shell aeroelastic stability. Small initial deviations of the shell's surface from its idealized shape were also shown to drastically reduce its resistance to panel flutter even though the deviations were only on the order of one shell thickness. Panel flutter instabilities in the presence of a laminar boundary layer profile were also found to be much less destructive to the shell than those originating in the presence of a turbulent profile.

Available in PDF, EPUB and Kindle. Book excerpt: The Vietnam War—a conflict defined by an ever-evolving mixture of conventional and guerrilla warfare and mass politics—has often been called a “war without fronts.” In fact, Vietnam had a multitude of fronts, as insurgents and counterinsurgents wrestled for control throughout 44 provinces, 250 districts, and more than 11,000 hamlets. In The Control War, Martin G. Clemis focuses on South Vietnam, where a highly complex politico-military struggle fragmented the battlefield along countless divergent points of conflict as both sides sought spatial and political hegemony. Complicating the conventional view that the Vietnam War was about winning “hearts and minds,” Clemis argues that both sides were more interested in asserting control over the people—and resources—of the countryside. As in other revolutionary civil conflicts, the key to winning political power in South Vietnam was to control the physical world of territory, population, and resources, as well as the ideational world of political organization and long-term legitimacy. Despite their countervailing purposes, both insurgency and pacification provided the means to exert this control. Proponents of each approach pursued the same goals, relying on a blend of military force, political violence, and socioeconomic policy to achieve them. Revealing the unique spatiality of the Vietnam War, The Control War analyzes the ways that both sides of the conflict conceptualized and used geography and the environment to serve strategic, tactical, and political ends. Clemis shows us that the operational environment of Vietnam, both natural and human-made, was far more than a backdrop to two decades of war.
