The program goal is to determine the applicability of novel energetic materials developed over the last few years, largely under funding by the Office of Naval Research, in electro-thermal chemical (plasma ignited) gun propellants. Particular interest lies in whether the new ingredients can achieve the desired ballistic response and energy goals for this system. A series of extensive thermochemical calculations on a wide range of potential formulations have been completed. A summary of the data generated has been prepared for distribution to an advisory team. Further activity has begun on procurement of critical materials that are essential for the additional tasks, including some initial formulation safety (compatibility) tests. The baseline study focused on sixteen different formulations, containing 24% binder as a representative level with a primary solid making up the bulk of the formulation. A secondary solid was added at five percentages: O,6,12,18, and 24 percent.

A new series of cool burning, high impetus, low molecular weight gun propellants has been identified. These propellants contain either cyclic or linear nitramines as crystalline oxidizers in the propellant matrix. Current development efforts are concentrating on lowering the inherently high pressure exponent of the linear burning rate associated with these high energy systems. When these advanced formulations become operational, thermal barrel erosion will be virtually eliminated, hypervelocity projectile firing from operational guns will become possible, and the potentiality for catastrophic failure resulting from the use of aluminum cartridges will be removed. To realize these benefits, the nitramine combustion anomaly must be obviated. (Author).

Recent requirements for hypervelocity projectile launch for strategic U.S. Army missions have led to the proposal of a variety of gun propulsion systems. Among these systems are those that utilize solid propellant along with electrothermal-chemical (ETC) augmentation. Advanced solid propellant systems with complex grain geometry and loading configuration are also being investigated. In response to this need, the U.S. Army Research Laboratory (ARL) has, for a number of years, engaged in the study of solid propellant ignition using a hot, low molecular-weight plasma generated by ETC means. In addition, ARL is developing an ETC modeling capability using the next-generation interior ballistics code, NGEN, and a series of experimental studies in a ballistic simulator to generate code validation data. The current report demonstrates progress for application of the NGEN code to solid propellant, direct-fire gun systems in which various propellant configurations (i.e., grains and disks) are combined into a single charge in order to obtain higher-loading densities. The charge is ignited using the efflux from an ETC plasma capillary made of polyethylene. Comparison with pressure data measured in a 25-mm ballistics simulator, filled with disks of JA2 propellant as the main charge and a small amount of inert grains as filler, provides validation of the NGEN model with respect to the representation of the plasma efflux from an ablation capillary, into the chamber, and around propellant disks.

The primary objective of this effort is to identify a suitable replacement for medium caliber ammunition propellants that is environmentally more acceptable, has good safety properties, provides an increased level of performance, and maintains a reasonably low cost. This program is designed to develop an ETPE based gun propellant that meets these criteria. This program will provide three deliverables: first, the manufacture of a down selected ETPE based propellant formulation and the manufacture of twelve rounds of each 25 mm and 30 mm ammunition employing this ETPE based propellant; second, test data: 25 mm gun firing performance in reference to M-793 ammunition and 30-mm gun firing performance in reference to GAU8A ammunition; and third, reports documenting refinement and analysis of two ETPE based gun propellants.

Advanced energetic materialsâ€"explosive fill and propellantsâ€"are a critical technology for national security. While several new promising concepts and formulations have emerged in recent years, the Department of Defense is concerned about the nation's ability to maintain and improve the knowledge base in this area. To assist in addressing these concerns, two offices within DOD asked the NRC to investigate and assess the scope and health of the U.S. R&D efforts in energetic materials. This report provides that assessment. It presents several findings about the current R&D effort and recommendations aimed at improving U.S. capabilities in developing new energetic materials technology. This study reviewed U.S. research and development in advanced energetics being conducted by DoD, the DoE national laboratories, industries, and academia, from a list provided by the sponsors. It also: (a) reviewed papers and technology assessments of non-U.S. work in advanced energetics, assessed important parameters, such as validity, viability, and the likelihood that each of these materials can be produced in quantity; (b) identified barriers to scale-up and production, and suggested technical approaches for addressing potential problems; and (c) suggested specific opportunities, strategies, and priorities for government sponsorship of technologies and manufacturing process development.

This book contains papers presented at the NATO Advanced Research Workshop titled "Application of Gun and Rocket Propellants in Commercial Explosives". (SST.ARW975981) The workshop was organized in collaboration with codirector Dr. Bronislav V. Matseevich (KNIIM) and held in Krasnoarmeisk, Moscow Region, Russia, October 18-21, 1999. About 70 participants from 11 different countries took part in the meeting (Russia, Belarus, Czech Republic, Germany, Belgium, China, USA, Spain, Israel, Ukraine and the Netherlands). The workshop was principally the continuation of a previous NATO workshop on Conversion Concepts for Commercial Application and Disposal Technologies of Energetic Systems" held at Moscow, Russia, May 17-19, 1994 in the specific area of the reuse of gun and rocket propellants as ingredients in commercial explosives.

A theoretical, thermochemical propellant-performance computer program has been used at the Air Force Armament Laboratory to evaluate potential ingredients for advanced gun propellants. The program provides a good first approximation to propellant parameters such as impetus, flame temperature, and gas molecular weight. The program was used to evaluate the thermodynamic properties of advanced propellants containing ingredients being considered for further development. Sixteen of these ingredients with different binders were investigated and theoretical computations obtained.

In recent years, substantial improvements in the performance of solid propellant guns have resulted from the development of higher energy propellants, higher loading density propellant charge configurations, and propellant geometries and concepts that have provided the progressively increasing gas generation rates required to efficiently use available increases in total energy. Unfortunately, these same features also typically lead to increases in ammunition vulnerability to enemy threats. Coupled with the current interest in much lighter fighting vehicles, the need for ammunition with reduced rather than increased sensitivity is obvious. This report describes the development of a new approach in the U.S. Army to address propellant energy/ performance and sensitivity/vulnerability as a single set of critical design requirements, to be addressed concurrently from the very beginning of the new energetic material research and development cycle. Some elements of this work were presented in abbreviated form at the 19th International Symposium on Ballistics in Interlaken, Switzerland in May 2001.
