High Energy Components
Abstract
Abstract The goal of this work is to enhance the capabilities of the U. S. Navy in meeting the challenges presented by the ever increasing sophistication of the weapon systems of other nations. In order to move toward this goal, our objective will be to design, synthesize and characterize new high energy components with appropriate properties while concomitantly educating and training members of the work force of tomorrow. Theoretical or empirical calculations which will allow prediction of the likelihood and desirability of synthetic methodologies to reach the proposed materials based on density, heat of formation and detonation properties will aid markedly in guiding the selection of competitive compounds to be synthesized. The development and characterization of new energetic materials is an exciting and challenging area of chemistry from both fundamental as well as applied aspects. Considering the many applications of nonnuclear energetic materials as explosives or oxidizers, it is vital to discover new compositions with significant advantages over compounds currently used not only for military but also for civilian purposes. A new generation energetic material must meet a variety of standards in order to become widely accepted. In addition to performance properties, the desired criteria are a) insensitivity towards destructive stimuli such as electrostatic discharge, heat, friction, and impact in order to ensure safe handling procedures and enhance controllability of kinetic energy release; b) low solubility in water and hydrolytic stability for environmental concerns, and c) high thermal stability as well as longevity and compatibility questions and other criteria addressing high-priority ecological toxicity requirements. In the attempt to make major improvements in the properties of known energetic components or producing entirely new energetics, work will proceed along several lines which include at least the following: a) Modify nearly competitive compounds obtained earlier (N00014-12-1-0536) to bring them into the useful range (usually enhancing insensitivity by introducing new functionalities). b) Develop new N?oxide heterocycles. c) Develop new bridged ethylene compounds. d) Develop new linked oxadiazoles. e) Systematize new compound development through synthesis by design. f) Develop new structural goals guided by experimental results and based on preliminary calculations and continuing literature search. Preliminary calculations on the range of compounds from each of these groups are very encouraging with respect to predicted high density, and good detonation properties which leads to optimism about the value of the outcome of this research. This work will be supported and driven throughout the project by theoretical calculations and the literature will be monitored constantly for new methodologies and compound structures.
