- 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 demonstrated. 1. Insensitivity Testing and Requirements: Small scale (laboratory scale) Insensitive Munitions (IM) tests for cook-off, bullet/fragment penetration and shape charge impact will be used to determine insensitivity using the procedures described in NAVSEA INSTRUCTION 8020.5C, of 05 May 2000. Enclosure (3) of NAVSEA INSTRUCTION 8020.5C provides detailed procedures to be followed in laboratory testing for insensitivity. Requirements are (1) Fast and slow cook-off: No reaction more severe than controlled burning (i.e., the rate of combustion is constant). (2) Bullet/fragment penetration: Unreactive or no response more severe than controlled burning. (3) Shape charge impact: No reaction more severe than controlled burning. (4) Sympathetic detonation: No detonation from 25 grams of explosive system energetic material (as configured in the explosive system) at the same distance at which 25 grams of TATB is detonated by 25 grams of C-4 (initiator explosive). 2. Switching Mechanism: Successfully demonstrate in laboratory scale experiments a mechanism to transition or dial from insensitive state to state where energy release (detonation) is achieved. 3. Full Energy Release and Requirement: Demonstrate the end state of the system will result in detonation with at least the following characteristics: The explosive energetic system must demonstrate at least 70 percent of the detonation effectiveness of the calculated output. Phase II Program Requirements?Larger scale, integrated components system demonstration. The system for Phase II is defined as the optimization of the system components demonstrated in Phase I such that upon integration of the components the size, weight and volume of the system are commensurate with existing warheads while still meeting the specific metrics of Phase I. SUBMISSION OF WHITE PAPERS: We strongly encourage white papers in advance of full proposals. Each white paper will address concept technical issues and capabilities of the proposing organization. The white paper should clearly describe the core concept behind the binary energy management including switching mechanism and scheme to achieve switching mechanism for the system proposed and provide estimated or calculated energy content (kcal/cc and kcal/g) for the concept system. The white paper should discuss the rationale for why the proposed system cannot be compromised, and estimate the size of the final system. White papers should be a maximum length of 8 pages [11 or 12 font size] including graphics and drawings. No more than one concept is to be addressed in a single white paper. Multiple white papers from a single source are acceptable. White papers sent in response to this solicitation are due NO LATER THAN 1600 HOURS ET APRIL 26, 2005. DARPA recommendations and requests for a full proposal submission to include cost and schedule information for Phase I only will be made within approximately thirty (30) days of that date. Proposers will be given until June 23, 2005 to respond with submission of the full proposal. DARPA reserves the right to request full proposals from any specific sections of any white paper submission and/or to encourage teaming between proposers and/or other entities. To facilitate the submission of white papers, a website http://www.sainc.com/dso0519 has been set up. For more detailed instructions on submitting white papers, please refer to the instructions for BAA05-19 found at the website http://www.darpa.mil/baa/baa05-19. FORMAT AND CONTENT OF FULL PROPOSALS: Follow general guidelines for full proposal format and content provided at http://www.darpa.mil/baa/baa05-19. To receive consideration under this addendum, PROPOSALS ARE DUE AT DARPA NO LATER THAN 1600 ET June 23, 2005. Proposals received after that date will be considered under the open BAA only.
