- BINARY ENERGY MANAGEMENT Program (BEM), SOL BAA05-19 Addendum 5, Due: June 23, 2005 POC: Dr. Rosemarie Szostak, DARPA/DSO, Ph: 571-218-4588, Email: BAA05-19@darpa.mil; Website Submission: http://www.sainc.com/dso0519. PROGRAM GOALS: This BAA request proposals for enabling technologies for high explosive systems such that the system can be switched from a state that is completely unreactive (will not detonate) to a fully sensitive energetic system. The scheme used to facilitate the mechanism of transition cannot be compromised, i.e. the scheme by which the system is switched requires an external action without which the system will remain inert. It is also important that the amount of energy that the energetic system can release is not diluted to achieve the inert state. The ability to achieve a continuum of performance between an inert and a sensitive state is desirable but not required. It is not the intent of the DARPA Program to develop high explosive warheads through this BAA. Rather, this program will demonstrate enabling technologies required for ultimate development of such systems. Therefore, solutions proposed in response to this BAA must be consistent with size/weight/volume requirements of existing warheads. BACKGROUND: Sensitivity of energetic materials to unexpected impact, friction, shock waves, and thermal loading is a critical military issue. This concern has led to the formulation of new safety requirements for munitions and the desire for the development of insensitive munitions (IM). The requirements for safety are described in Title 10 US Code, Chapter 14, Section 2389 and in DoD Directive 5000.1. Present IM development has focused on a combination of less sensitive energetic fill formulations, mitigation techniques and packaging. Though more insensitive then their predecessors, the present energetic fill formulations fall far short of the goal of being totally insensitive. These less sensitive formulations also lack the properties of the prior sensitive energetic material [total energy content, pressure pulse, and detonation velocity]. The present approach to achieve insensitivity of fill formulations relies on dilution of the energetic component relative to the binding resulting in less desirable total energy content, pressure and detonation velocity upon initiation. PROGRAM OBJECTIVES: The objective of this two phase program will be to develop a system containing an energetic fill and a control scheme that can demonstrate a mechanism by which the energetic fill can be switched between completely insensitive mode and full energy release. This control scheme cannot be compromised and the output of energy when the system is detonated cannot be diluted to obtain insensitivity. An ideal system for this program is defined as having a detonation effectiveness equivalent to or exceeding CL-20 (Edet = 317 kcal/cc, Pcj = 420 kbar) In Phase I (not to exceed 12 months) performers will demonstrate at the laboratory bread-board level the end states of their system that is 1) the insensitive mode (state) and 2) full energy release mode and the mechanism by which these modes can be switched. Energy release in Phase I need not be optimized but should constitute at least 70 percent release of the total energy (Edet and Pcj). In Phase II the performers will integrate the scheme used to achieve the switching mechanism with the fill and optimize energy release for maximum energy output (Edet and Pcj). Performers will also demonstrate that the system (fill and switching scheme) cannot be compromised under the requirements for insensitive munitions, i.e., the system will not detonate under the specific assaults of cook-off, penetration, and sympathetic detonation. Phase I Program Requirements—Laboratory bread-board demonstration of principle. The insensitivity and energy content of the fill and the mechanism for switching or dialing between insensitive to sensitive will be demonsthing in their implications, innovative, and ambitious in their goals and implementation. We encourage the submission of white papers and proposals that provide solutions to one or both of the challenge problem variations. It is anticipated that to provide these solutions, research efforts will have to address one or more of the following areas: 1. New mathematical methods that will enable the development of nonlinear multiscale spatiotemporal models of physical systems that exhibit nonlinear dynamics. We are specifically encouraging efforts that provide a methodology for the design of experiments in coupled nonlinear systems to support the development of models and which can characterize the effects of unmodeled dynamics upon the outputs of the model. We strongly discourage methods that do not exhibit linear scaling with the number of parameters in the model. 2. New methods that reduce the computational complexity of nonlinear models resulting in a nonlinear model with less complex dynamics and for which the impact of reducing the model can be quantified by guaranteeing the performance of the system as well as providing bounds on the performance of the system as a result of simplifying the model. 3. We are also interested in computational strategies that will minimize the computational costs associated with the evaluation of a nonlinear model while maintaining an appropriate precision in control or optimization applications. 4. Analysis methods and computational techniques that enable the propagation of uncertainty through coupled nonlinear systems. In particular these new methods must be capable of accounting for branching in the dynamics, accounting for non-Gaussian probability distributions associated with parameters of the models, sensor noise, and initial conditions. 5. New numerical methods for the estimate of the probability distribution function for the outputs of coupled nonlinear dynamical systems on multiple spatiotemporal scales that are faster and more computationally efficient than Monte-Carlo simulation or particle filter methods for a given non-Gaussian distribution of input parameters, model uncertainty, and reduction of the dynamics. 6. Methods to control and, if required, optimize the performance of large federated nonlinear systems with dynamics on multiple spatiotemporal scales. We strongly discourage white papers and proposals that rely on methods that attempt to linearize the dynamics and then apply established methods such as a Kalman Filter. We are also discouraging white papers and proposals that attempt to solve the challenge problems by application of known nonlinear control methods and that do not involve the development of new mathematical methods. RUM is envisioned as a three-phase program that leads to the solution of the challenge problem by developing new methods for the solution of coupled nonlinear dynamical systems in the face of uncertainty. Each phase of RUM will consist of a twelve-month period of performance. In the first twelve-month phase of RUM, the focus will be the development of new methods focused upon the challenge problem variants. At the conclusion of the first phase we expect to test the new methods by simplifying the challenge problem to a large coupled system that has linear dynamics and Gaussian distributions associated with the probability distribution functions of all uncertainties. At the conclusion of Phase 1 the efficacy of the new methods will be verified by comparing their predicted results against standard techniques for these problems. The second twelve-month phase may include a down-select of Phase 1 efforts. The down-selection criteria may include success in the verification process described above. The focus of Phase 2 will be in refining and demonstrating that the new methods developed for the challenge problem can be applied to the special case of a large linear system with non-Gaussian distributions of input parameters and produce results that are consistent with Monte Carlo or particle filtering methods but at reduced computational costs. The final phase will consist of 12 months and may include another down-select based partially upon success in verifying performance at the conclusion of Phase 2. During the third phase, the methods developed will be applied to the challenge problems leading to a design with performance guarantees in the presence of uncertainty, demonstration of design of experiments to produce complex nonlinear models, and the application of the design of experiments methodology to produce reduced complexity models whose effect upon the design can be assessed in the face of sensor errors and uncertainty in initial conditions. Authors of white papers and proposals may include an optional task in which the system design can be tested experimentally. WHITE PAPER REQUIREMENTS. White papers must lead to a solution of either variant of the challenge problem and the solution must be based upon the development and application of new mathematics. We strongly discourage white papers that focus on the design of new sensors, data collection efforts, linearization of the system, or application of known nonlinear control methodologies to address the challenge problem. We are also strongly discouraging white papers and proposals that focus on experimentally determining conditions that lead to a solution of the challenge problem. We encourage the formation of interdisciplinary teams integrated toward solutions to these challenge problems. It is essential that the preparation of white papers include the following areas: 1. A clear statement of the envisioned utility of the proposed research and development. We are looking for revolutionary applications and goals that could be enabled if the proposed work is completed successfully. The vision for the program should be long term and may exceed the period of performance while the goals and deliverables should reflect the actual period of performance; 2. A concise statement of the research challenges, approach, and potential anticipated solutions to the challenges that will be addressed. This should include explicit timelines for which progress toward the goals can be determined and measured. Intermediate milestones of approximately 12-month periods with demonstrable metrics of performance must be included for the proposed work; 3. A cost estimation for resources required for the proposed timeline; and 4. The white paper should consider phases of development as the challenges are met. White papers must be received by 1600 ET March 22, 2005. Please put the phrase “Robust Uncertainty Management” in the title of the white paper. If the authors of white papers choose not to submit electronically, U.S. mail may be used. White papers will not be accepted by way of facsimile transmissions. Authors of white papers will be notified by April 22, 2005, if a full proposal will be requested. Full proposals must be submitted no later than 1600 ET May 23, 2005.
